SpaceX unveils third drone ship for landing Falcon 9 boosters

9:34 am

Capitalism in space: SpaceX’s founder Elon Musk yesterday unveiled the completion of its third drone ship for landing Falcon 9 boosters in the ocean and returning them to port.

The new ship will be put in place in Florida to support Atlantic launches of Falcon Heavy and the flagship rocket of SpaceX, the Falcon 9, that regularly sends Starlink broadband satellites to orbit and NASA astronauts and cargo to the International Space Station, among other customer requests.

This will give the company two drone ships in Florida and one in California, allowing them to do launches at an even faster pace than the one launch every 2 weeks or so since the beginning of the year. The ship also is designed to be more efficient than the older ships, no longer requiring a tug to take it out into the Atlantic.

Superheavy passes first tank test

9:17 am

Superheavy after tank test, July 12, 2021
Screen capture from NASASpaceflight.com live stream,
shortly after tank test of Superheavy

Capitalism in space: SpaceX’s first fullscale complete Superheavy prototype, dubbed #3, passed its first tank test yesterday.

Booster 3 was likely filled with a few hundred tons of liquid nitrogen relative to the more than 3000 tons its tanks could easily hold and the fraction of that total capacity SpaceX’s suborbital launch site can actually supply. Teams have been working around the clock for months to outfit Starship’s first orbital launch site with enough propellant storage for at least one or two back to back orbital launches – on the order of 10,000 tons (~22M lb) – but the nascent tank farm is far from even partially operational. That’s left SpaceX with its ground testing and suborbital Starship launch facilities, which appear to be able to store around 1200 tons of propellant.

Assuming the suborbital pad’s main liquid oxygen and methane tanks can also both store and distribute liquid nitrogen, which isn’t guaranteed, SpaceX thus has the ability to fill approximately 30-40% of Super Heavy B3’s usable volume. Frost lines aren’t always a guaranteed sign of fill level but if they’re close, SpaceX likely filled Booster 3’s tanks just 5-10% of the way during the rocket’s first cryoproof.

While the company still says it is aiming for a July orbital launch, that seems highly unlikely. They still have to do a Superheavy tank test with full tanks, plus static fire tests. They also need to get the orbital launchpad finished, with a full tank farm.

Nonetheless, SpaceX is moving fast towards flight of this heavy lift reusable rocket. I still think the odds are 50-50 it will complete its first orbital flight before SLS, even though its development began more than a decade later and has cost a tenth of the money ($6 billion vs $60 billion).

The bell of freedom rings in space

12:31 pm

The Liberty Bell
“Proclaim liberty throughout all the land unto all
the inhabitants thereof.” Photo credit: William Zhang

Not surprisingly the mainstream press today was agog with hundreds of stories about Richard Branson’s suborbital space flight yesterday on Virgin Galactic’s VSS Unity spaceplane.

The excitement and joy over this success is certainly warranted. Back in 2004 Branson set himself the task of creating a reusable suborbital space plane he dubbed SpaceShipTwo, modeled after the suborbital plane that had won the Ansari X-Prize and intended to sell tickets so that private citizens would have the ability to go into space.

His flight yesterday completed that journey. The company he founded and is slowly selling off so that he is only a minority owner now has a vehicle that for a fee can take anyone up to heights ranging from 50 to 60 miles, well within the U.S. definition of space.

Nonetheless, if you rely on the media frenzy about this particular flight to inform you about the state of commercial space you end up having a very distorted picture of this new blossoming industry. Branson’s achievement, as great as it is, has come far too late. Had he done it a decade ago, as he had promised, he would have achieved something historic, proving what was then considered impossible, that private enterprise, using no government resources, could make space travel easy and common.

Now, however, he merely joins the many other private enterprises that are about to fly into space, with most doing it more frequently and with far greater skill and at a much grander scale than Virgin Galactic. His flight is no longer historic. It is merely one of many that is about to reshape space exploration forever.

Consider the upcoming schedule of already paid for commercial manned flights:

Northrop Grumman wins contract to build Lunar Gateway’s habitable module

10:03 am

Capitalism in space: NASA yesterday announced that it has awarded Northrop Grumman the construction contract for building HALO, (Habitation and Logistics Outpost), the module where astronauts will live and work on its Lunar Gateway space station.

Combined with earlier development contracts this contract, worth $935 million, brings the total fixed-price cost to about $1.1 billion.

[HALO], one of the first for the Gateway, will serve as a habitat for visiting astronauts and a command post for the lunar orbiting facility. It will have docking ports for Orion spacecraft, cargo vehicles like SpaceX’s Dragon XL and lunar landers, as well as for later modules to be added by international partners. HALO is based on the Cygnus spacecraft that Northrop Grumman uses to transport cargo to the International Space Station, but extensively modified with docking ports, enhanced life support and other new subsystems.

This module is not expected to launch before 2024. Moreover, it is supposed to work in conjunction with what NASA calls its Artemis 3 mission, the third launch of SLS and the first to dock with Gateway. SLS however is so far only funded through its first two flights, and has a schedule that is presently highly uncertain.

There is great irony here. HALO, based on the Cygnus cargo freighter, will be about that size. If the present schedule for SpaceX’s Starship continues as expected, it will be flying to the Moon at about the same time, and will have a cargo bay big enough to store several Cygnus freighters inside. And though no work has yet been done to make that cargo bay habitable, Starship’s cost per launch, about $2 million, is so far below the $1.1 billion cost for HALO that it will certainly cost much less than HALO to make it a habitable station. And it will be gigantic in comparison.

FAA initiates new prelaunch air space clearance system

9:33 am

FAA has now begun using a new prelaunch air space clearance system that is intended to shorten the time airplane travel is disturbed by the scheduled launch of a rocket.

[The FAA] developed the Space Data Integrator (SDI) tool to reduce how long ATO must close airspace around space launches and reentries. The system is voluntary. SpaceX, Blue Origin, Firefly, and the Alaska Aerospace Corporation are current partners. SDI was first used operationally for SpaceX’s Transporter-2 launch last week and is being used for the SpaceX-22 Cargo Dragon reentry today.

…Space operators now are voluntarily sharing telemetry data including vehicle position, altitude and speed, as well as data if the vehicle deviates from its expected flight path. Asked when additional companies might join, Monteith said he would have to defer to ATO to answer that question.

…Using the automated SDI system coupled with “time-based procedures and dynamic windows,” the FAA expects to be able to shorten airspace closures “from an average of more than four hours per launch to just more than two hours” and eventually less.

The article makes no mention whether this new system will allow the FAA to shrink the closure areas as well, which was Elon Musk’s main complaint after SpaceX’s Transporter-2 launch near the end of June was scrubbed seconds before launch when a helicopter slipped into that airspace. As Musk wrote in a tweet,

Unfortunately, launch is called off for today, as an aircraft entered the “keep out zone”, which is unreasonably gigantic. There is simply no way that humanity can become a spacefaring civilization without major regulatory reform. The current regulatory system is broken.

I suspect there is discussion to reduce the size of the closure areas, but I also suspect that the FAA is resisting industry calls to do so.

Problems with Blue Origin’s engine force more delays of ULA’s new Vulcan rocket

10:28 am

In a detailed and very informative review of the partnership between ULA and Blue Origin yesterday, Eric Berger at Ars Technica noted these unfolding facts:

For years, United Launch Alliance chief executive Tory Bruno had been saying the new Vulcan rocket, powered by two [Blue Origin] BE-4 engines, would launch in 2021. However, he recently told Aviation Week the first launch would slip into 2022. Bruno said this was due primarily to the mission’s customer, Astrobotic, whose Moon lander was not ready. Technically, Bruno said, Vulcan still had a chance to be ready for a 2021 launch.

This seems highly unlikely because it is already July, and United Launch Alliance (ULA) still does not have a pair of flight engines. After receiving the flight engines from Blue Origin, ULA needs to attach them to the Vulcan rocket, roll it to the launch pad, and conduct a lengthy series of tests before a hot-fire ignition. After this hot-fire test, the rocket will be rolled back to the hangar and prepared for an actual launch attempt. As of January, Bruno was saying this hot fire test with the flight engines would take place this summer. That will no longer happen.

In December both companies promised delivery of those flight engines by this summer, but so far nothing has arrived. Moreover, both companies have remained very tight-lipped about the cause of the most recent delays. In October 2020 Bruno said that an issue with the engine’s turbopumps had been identified and fixed, but if so why has the engine not arrived as promised?

A GAO report released last month had described issues with the engine’s “igniter and booster capabilities,” but Bruno himself has denied the igniter was a problem.

Regardless, Blue Origin’s inability to deliver this engine is causing problems at both companies. Both have been forced to delay the launch of their new orbital rockets. Both rockets were initially scheduled to launch in 2020, were delayed to 2021 about two years ago, and now are likely not to launch until 2022.

While ULA can still switch to its Atlas 5 rocket for some planned Vulcan launches (and has already done so), that rocket is more expensive and thus eats into the company’s profit margin. Using the more expensive Atlas 5 in bidding also makes it more difficult for ULA to compete with SpaceX in any head-to-head competition.

Blue Origin does not even have this option. Its proposed New Glenn rocket is grounded until it gets its engine operational.

All told, the failure of Blue Origin to deliver here is essentially grounding all of SpaceX’s potential American competition, a situation that is not healthy for the American rocket industry.

SpaceX drone ship arrives in California

9:14 am

Capitalism in space: One of SpaceX’s two drone ships used by its Falcon 9 first stages for ocean landings has arrived in California in preparation for frequent Starlink launches from Vandenberg Space Force Base.

The journey began on the East Coast two weeks ago and included passage through the Panama Canal. Once the drone ship gets offloaded, it will be based at Pier T, where it be part of recovery operations for the Starlink landings that potentially could occur in late July or early August.

These California launches will allow SpaceX to increase the global coverage of its Starlink constellation. It will also allow the company to begin frequent launches from both coasts.

Progress docks with ISS

12:36 pm

As expected a Russian Progress freighter docked with ISS yesterday, on schedule and with no mishaps.

I report this non-news story simply because of the Russian claim yesterday that a SpaceX Starlink satellite and Falcon 9 upper stage threatened a collision with that freighter as it maneuvered in orbit prior to docking.

Not surprisingly, there was no collision. The Russians knew this, or they would never have launched as they did. They made a stink about it as a ploy to stain SpaceX, a company that has taken almost all their commercial launch business by offering cheaper and more reliable rockets.

Judge rules SpaceX must comply with Justice subpoena

9:22 am

A federal Judge has ruled that SpaceX must comply with Justice Department subpoena demanding its full hiring records in connection with an investigation by the agency’s Immigrant and Employee Rights Section about SpaceX’s decision to not to hire a non-citizen.

However, the DOJ unit is not only investigating the complaint, but also has said it “may explore whether [SpaceX] engages in any pattern or practice of discrimination” barred by federal law. Investigators in October issued a subpoena demanding that SpaceX provide information and documents related to its hiring and employment eligibility verification processes, to which SpaceX has not fully complied.
Hiring policies in place

SpaceX’s lawyers argued in court that the DOJ’s probe is overbearing given the original complaint. “No matter how generously ‘relevance’ is construed in the context of administrative subpoenas, neither the statutory and regulatory authority IER relies on, nor the Fourth Amendment to the U.S. Constitution, permits IER to rifle through SpaceX’s papers on a whim and absent reasonable justification,” SpaceX said. “And even if IER could somehow belatedly justify its current investigations, IER’s subpoena is excessively overbroad. IER’s application for an order to comply with the subpoena should be denied,” the company added.

There is another component that suggests this investigation is bogus and is intended as an attack by the government against SpaceX. The company makes rockets, and it must be extra careful about its hiring of any foreign national. So, on one hand the government forbids SpaceX from hiring foreigners, and on the other hand the government is condemning SpaceX for not doing so.

Moreover, it does appear that Justice is going on a fishing expedition in SpaceX’s files, something it is forbidden to do according the fourth amendment of the Constitution. A search such has this can only occur when there is evidence a specific crime has occurred. The search Justice wishes to do is broad and unreasonable, not based on any specific allegations but merely to “explore” SpaceX records to find a crime.

We have only just begun. The law and the Constitution means little to many in the Biden administration, in Washington, and in our government in general. What matters is power and the ability of these thugs to tell everyone else what to do. It looks like they increasingly have SpaceX in their sights.

Russia: Progress freighter and SpaceX rocket/satellite to have near miss

9:00 am

According to a Russia news outlet, their just launched Progress freighter will have a near miss today prior to its docking with ISS with two SpaceX objects, a Falcon 9 upper stage and a decommissioned Starlink satellite.

The Progress spacecraft, which carries about 3,600 lbs. (1,633 kilograms) of cargo including food, fuel and other supplies to the orbital outpost, launched from Roscomos’ Baikonur cosmodrome in Kazakhstan at 7:27 p.m. EDT (2327 GMT) on Tuesday (June 29). Progress 78 will approach the two objects about three and a half hours before its docking at the International Space Station, which is scheduled for 9:02 p.m. EDT on July 1 (0102 July 2 GMT).

The close approach, which triggered a potential collision alert, was detected by the Roscosmos TsNIIMash Main Information and Analytical Center of the Automated System for Warning of Hazardous Situations in Near-Earth Space (ASPOS OKP), Roscosmos said in the statement issued on the space agency’s website Wednesday (June 30) at 7:47 a.m. EDT (1147 GMT).

Based on preliminary calculations, the Starlink 1691 satellite will be just 0.9 miles (1.5 kilometers) away from Progress 78 on Thursday (July 1) at 5:32 p.m. EDT (2132 GMT). Three minutes later, a fragment of a Falcon 9 rocket booster left in orbit in 2020 is expected to approach the spaceship within 0.3 miles (500 meters).

Based on that timetable, the near miss has already occurred. No word yet on whether there were any issues.

What is interesting is that Russia should have known this prior to launch. It is routine procedure to consider known orbital objects in scheduling liftoffs. Either they knew and decided to purposely fly this close for political reasons (it allows them to slam SpaceX while also touting the dangers of space junk) or had not done their due diligence before launch.

SpaceX successfully launches 88 smallsats, marking a renaissance in rocketry in 2021

1:07 pm

null
First stage landing at Cape Canaveral today

Capitalism in space: SpaceX today successfully used its Falcon 9 rocket to place 88 smallsats into orbit, the third rocket launch today.

While Transporter-2 won’t beat the unprecedented number of satellites launched on on Transporter-1 [the first such smallsat launch by SpaceX earlier this year], SpaceX says it will still “launch 88 spacecraft to orbit” and – more importantly – carry more customer mass. In other words, Transporter-2 will carry roughly 50% fewer satellites, each of which will weigh substantially more on average.

Ordering directly through SpaceX, [the price] begins at $1 million for up to 200 kg (~440 lb). … A majority of small satellites weigh significantly less than 200 kilograms but if a customer manages to use all of their allotment, the total cost of a SpaceX rideshare launch could be as low as $5000 per kilogram – incredibly cheap relative to almost any other option. For a [comparable] launch … on a Rocket Lab Electron or Astra Rocket 3.0 rocket using every last gram of available performance, the same customer would end up paying a minimum of $25,000 to $37,500 per kilogram to orbit.

The launch also included a handful of Starlink satellites, adding to SpaceX’s constellation. I have embedded SpaceX’s live stream below the fold. As I write this the satellites have not yet been deployed from the second stage, but that should happen shortly.

The first stage landed successfully, the eighth time this booster has done so. The fairings were also reused, completing their third flight. All told, this was SpaceX’s 20th launch in 2021, 18 of which used reused boosters.

SpaceX launch scrubbed because airplane strayed into what Musk calls “an unreasonably gigantic” launch zone.

9:33 am

Capitalism in space: Yesterday a SpaceX Falcon 9 launch was scrubbed mere seconds before launch because an airplane had been detected inside the government’s keep-out zone.

The scrub was called by the range officer at T-11 seconds. SpaceX will attempt the launch again today.

Musk immediately blasted the size of that keep-out zone, which was established decades ago at the very beginnings of the space race and has not been adjusted as launch technology has improved.

“Unfortunately, launch is called off for today, as an aircraft entered the ‘keep out zone,’ which is unreasonably gigantic,” Musk tweeted Tuesday afternoon. “There is simply no way that humanity can become a spacefaring civilization without major regulatory reform. The current regulatory system is broken.”

Musk has successfully forced the range to accept new technology that simplifies launches, makes it possible for them to occur faster with less time in-between, and requires fewer range officials monitoring the launch. He is now pushing them to rethink the size of the range, which is likely much larger than now necessary, as Musk claims, because not only are rockets more reliable, their programming is more precise.

The article at the link also notes as an aside at the end another Musk tweet, that SpaceX’s Starlink network now has 70,000 customers and hopes to have 500,000 within a year. More on that story here.

First orbital Raptor engine delivered to Boca Chica

10:59 am

Capitalism in space: SpaceX has delivered to its Boca Chica launch site the first Raptor vacuum engine optimized for orbital operation.

The Starship prototype that will use this engine, as well as fly on the first orbital test flight, is #20.

While most of S20’s upgrades are a mystery, the ship’s thrust dome – spotted in work at Boca Chica earlier this month – has already confirmed that the prototype will be the first with the necessary hardware for Raptor Vacuum engine installation. That likely means that S20 will also be the first Starship to attempt to static fire six Raptor engines*, potentially producing more thrust than a Falcon 9 booster. On June 27th, one such vacuum-optimized Raptor (RVac) arrived in Boca Chica for the first time ever, making it clear that the comparatively brand new engine may already be ready to start integrated Starship testing.

*Update: SpaceX CEO Elon Musk says that the Raptor Vacuum delivered to Boca Chica on June 27th is, in fact, meant for Starship S20, seemingly confirming that the prototype will fly with a full six Raptor engines.

While this delivery as well as statements by both Musk and Gwynn Shotwell, SpaceX CEO, all point to an intended orbital test flight in July, the article at the link outlines the many tasks still undone that must be completed before that flight, all of which suggest that it will be August at the earliest before that flight can happen.

Nonetheless, SpaceX is barreling forward toward that first orbital flight, with clearly a goal to beat SLS’s first orbital flight, presently scheduled for November.

OneWeb signs deal with BT, Britain’s biggest telecommunications company

9:08 am

Capitalism in space: OneWeb has signed a deal with BT (formerly British Telecom) where BT will test the use of OneWeb’s satellites to provide internet to remote regions in Great Britain.

The tie-up with Oneweb will come as a major boost to BT as it ramps up its efforts to roll out full-fibre broadband across the country. The telecoms giant recently hiked its target to 25m premises by the end of 2026. However, BT has previously warned that regulatory hurdles and geographic challenges could slow down the project. The companies said they would explore how a partnership could boost capacity, mobile resilience, backhaul and coverage in remote locations.

This means that OneWeb and SpaceX’s Starlink are now in direct competition for customers in the rural areas of Great Britain. While a Starlink customer uses their own dish to communicate directly to the SpaceX satellite constellation, OneWeb is designed to have many nearby customers first link via a ground network to a much larger single dish, in this case something that BT would provide, which will then send the data to the satellite constellation.

I have no idea which design is better. For customers however the existence of two options is great, and will guarantee better service and lower prices.

Many of Mars’ geological mysteries, all in one photo

1:06 pm

Knobs, streaks, and lava channels on Mars
Click for full image.

Today’s cool image is fun because it contains a plethora of Martian mysteries, all packed into a very small space. The photo to the right was taken on April 29, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). I have rotated, cropped, and reduced it to post here.

The uncaptioned picture was labeled “Small Channel Winding between Knobs in Tartarus Colles.” The knobs, which can be seen on either side of the thin channel within the canyon, are actually a major Martian puzzle. Tartarus Colles has a lot of them, and planetary geologists are not really sure how they formed. One 2009 paper [pdf] suggested that the cones were formed by the violent interaction of lava and ice. This earlier paper [pdf] hypothesized that both water and lava had to be flowing over the surface at the same time, producing the steam and the energy that popped the lava cones, kind of like the small convection bubbles seen when tomato sauce simmers.

The scientific literature however is not deep, and there appears to be much uncertainty about this conclusion.

The photo however contains other major Martian puzzles.

SpaceX confirms it is shifting to Starship orbital test flights

10:24 am

Capitalism in space: By shifting both the 15th and 16th Starship prototypes to its garden at Boca Chica of retired spacecraft, SpaceX has essentially confirmed that it has shifted operations there from short test hops to Starship orbital test flights.

Built as the first of several planned backups to Starship SN15, which debuted a number of significant upgrades in April and May, it appears that Starship serial number 16 (SN16) has been retired to a display stand after its only sibling became the first full-size prototype to successfully survive a launch and landing on May 5th. SN16 actually reached its full height before SN15 lifted off and was more or less complete by May 10th. Since then, the prototype has remaining more or less untouched, seemingly waiting for SpaceX to decide its fate in lieu of Starship SN15’s major success.

Ultimately, with SN16 now sitting side by side with SN15 at what will likely become a sort of open-air SpaceX museum, it appears that the company has made up its mind.

In other words, prototype #16, though built and ready to fly, will likely never do so. Instead, the company is focusing its operations on preparing for the first orbital test flights using Starship prototype #20 stacked on top of a Superheavy, with the first flight planned to circle three-quarters of the globe to land in the Pacific northeast of Hawaii.

Since neither #20 nor its Superheavy are fully assembled, that flight will likely not occur in July, as SpaceX had initially suggested as its targeted launch date. However, with all work now focused on that orbital test flight, it is almost certain they will attempt it before the year is out.

The big question is whether Starship’s first orbital flight will beat out SLS’s first orbital flight, presently scheduled for November but expected to be delayed.

SpaceX successfully launches GPS satellite for Space Force

9:40 am

Capitalism in space: SpaceX today successfully launched a new GPS satellite for the Space Force.

As I post this the second stage has not yet deployed the satellite, though it is in orbit. UPDATE: As expected the satellite has been successfully deployed into its proper orbit.

This was the first Space Force launch using a reused Falcon 9 first stage. The stage, making its second flight, successfully landed on the drone ship, broadcasting the absolutely best video ever of such a landing, with the cameras on both the stage and the drone ship working without distortion throughout the landing to touchdown. The live stream is embedded below the fold, with that landing at 8:34 minutes after launch.

The two fairing halves are new but their pick up method for reuse has been streamlined:

For this mission, a new vessel has joined SpaceX’s oceangoing recovery fleet. HOS Briarwood will attempt to recover Falcon 9’s payload fairing halves after they splash down in the Atlantic Ocean. Similar in size to Shelia Bordelon, the previous temporary fairing recovery vessel, HOS Briarwood can be booked as a “flotel” and features an enormous crane, along with seemingly just enough deck space to support two recovered fairing halves.

Apparently, allowing the halves to land directly on the ocean surface and act as floating boat hulls until the ship can pick them up on a single ship, using a crane, is now the recovery method. There is also the hint that SpaceX might also be planning to sell tickets on this ship for people who wish a vacation watching that fairing recovery operation.

The leaders in the 2021 launch race:

19 SpaceX
17 China
8 Russia
3 Northrop Grumman

The U.S. now leads China 27 to 17 in the national rankings. Note: The average number of American launches per year during the 21st century (from 2000 to 2020) was 22. The U.S. has now topped that average by five launches, and the year is not even half over.

FAA, local Texas DA, and environmental group out to get SpaceX and Starship

10:16 am

Two news articles today suggest that a number of government officials, environmental groups, and some news media are beginning to team up to damage SpaceX and hinder its ability to succeed.

First we have this Verge article, aimed at suggesting that SpaceX violated its launch license and ignored FAA warnings not to launch during a December 9th test flight of the eighth Starship prototype.

Minutes before liftoff, Elon Musk’s SpaceX ignored at least two warnings from the Federal Aviation Administration that launching its first high-altitude Starship prototype last December would violate the company’s launch license, confidential documents and letters obtained by The Verge show. And while SpaceX was under investigation, it told the FAA that the agency’s software was a “source of frustration” that has been “shown to be inaccurate at times or overly conservative,” according to the documents.

The article generally takes the side of the FAA, suggesting that SpaceX was lax and nonchalant about the risks relating to weather and launch conditions, and proceeded with its launch even though FAA officials thought it unsafe. It also quotes Wayne Monteith, the head of the FAA’s space division, blasting SpaceX for showing “a concerning lack of operational control and process discipline that is inconsistent with a strong safety culture,” claiming that FAA software showed a risk to nearby buildings and homes should the rocket explode in the air.

However, buried far down in the article it also notes,

Another smallsat startup announces plans to build its own orbital space tug

9:34 am

Capitalism in space: The smallsat launch startup Launcher announced yesterday that it in addition to developing its own rocket, it plans to build an orbital space tug that can be used both by it and on other smallsat satellites.

Launcher, which announced a $11.7 million funding round June 2, said its Orbiter tug will be able to carry up to 150 kilograms of payload, either in the form of 90 units worth of cubesat deployers or larger satellites using standard smallsat separation systems. Orbiter can also accommodate hosted payloads with power, communications, and other capabilities. Orbiter is equipped with a chemical propulsion system using ethylene and nitrous oxide propellants. The vehicle will initially provide 500 meters per second of delta-v, or change in velocity, but that can be increased by adding more propellant tanks.

Orbiter is intended for use on Launcher Light, the small launch vehicle the company is developing, with a first launch projected in 2024. However, Orbiter is also capable of flying on other launch vehicles using an ESPA Grande adapter ring. Orbiter’s first mission is scheduled for October 2022, when it will fly on a SpaceX Falcon 9 rideshare mission.

That makes about four companies, Launcher, Momentus, Spaceflight, and D-Orbit, building space tugs for use on smallsats. Some will be on board a Falcon 9 launch set for later this month.

Some Starlink units shut down if weather gets too hot

9:27 am

Capitalism in space: Some users of SpaceX’s Starlink internet dishes have found that the units shut down if the local weather gets too hot.

The units presently being distributed to customers are beta units, designed to test the system before SpaceX rolls out full commercial availability, so finding such issues is not unexpected. According to one engineer quoted at the link,

Engineers could change Dishy’s mechanical design to achieve better heat rejection, change the dish’s electrical components to expand its thermal operating window, or develop a feature that allows Dishy’s components to operate at reduced power to create less heat. He noted the latter two options would likely be taller orders. “If changes to Dishy’s mechanical design are insufficient to reject heat at a rate exceeding its ability to produce it, software changes will be required to make the system more thermally efficient,” Keiter said. “But if speed limiting and system optimization can’t fix the issue, it will require a significant hardware revision for the commercial launch.”

“Since they’ve got a lot of custom silicon in there—likely the limiting factor—the turnaround time on this would be very slow,” he added. “They could resort to some form of active heat removal like fans or thermoelectric cooling, but then they burn a ton of power which would make Dishy even more power hungry than it already is.”

“This is a really tricky engineering problem with some insanely tight constraints,” Keiter said. “The good news is that the team is pretty sharp.”

SpaceX’s focus shifts from Starship hops to the first near-orbital flight

8:48 am

Capitalism in space: Work at SpaceX’s Boca Chica spaceport in Texas has now definitely shifted away from doing Starship short hops, focusing instead on the first near-orbital flight using both Starship and Superheavy.

Not only is almost all recent work at Boca Chica centered on building the orbital launchpad with its tower for Superheavy, the company has apparently decided to end development of Starship prototypes 15-19, designed for hops only.

The fate of Starship SN15, following its milestone success with a smooth test flight and landing last month, is still unknown. It is likely awaiting preparations to go on display at Starbase. It is already sitting on display stands.

SN16 continues to reside in the High Bay, all but ready for rollout to the suborbital pad. However, that appears increasingly unlikely, as SpaceX focuses on the upcoming orbital attempt from the launch site next door to where SN15 completed its momentous test.

SN17’s fate is known, with sections of what was to become that Starship now observed as being scrapped at the Production Site.

Meanwhile, SN20’s aft dome [intended for orbit] has also been spotted by Mary (@bocachicagal), sporting three mounts for RVacs, indicating SN20 may be the first Starship to fly with both sea level and vacuum optimized engines.

All signs continue to suggest that orbital test flight will occur before the end of the summer.

Bezos to fly on first manned New Shepard suborbital flight in July

8:52 am

Capitalism in space: Jeff Bezos announced today that he and his brother Mark will be passengers on the first manned commercial New Shepard suborbital flight, now scheduled to launch on July 20th.

“I want to go on this flight because it’s a thing I wanted to do all my life. It’s an adventure. It’s a big deal for me,” Bezos says in the brief video.

In that video, Bezos asks his younger brother Mark, to accompany him on the flight. “I think it would be meaning to have my brother there,” he said.

Mark Bezos accepted. “I wasn’t even expecting him to say that he was going to be on the first flight,” he said in the video. “And when he asked me to go along, I was just awe-struck.”

Right now the high bid in the auction for the other passenger seat remains stuck at $2.4 million. The bidding ends on June 12 with a live auction instead of an online one, but it appears that whoever bid that amount has no competitors and will be the passenger.

As for Bezos’ flight, his announcement means he will beat out Richard Branson for this honor. Bezos’ victory is especially embarrassing to Branson, who had been promising everyone that he would be the first suborbital passenger on his Virgin Galactic SpaceShipTwo suborbital spacecraft for almost twenty years. Those promises were bunkum. Bezos meanwhile made no such promises, and will deliver.

If you had to choose between these two car salesmen, who would you pick?

I however would choose neither. These suborbital car salesmen are fighting over the honors to launch what is equivalent to a rowboat. Elon Musk’s SpaceX is meanwhile building the equivalent of an ocean liner (Starshp) even as it is about to launch the equivalent of the first passenger steam ship (Falcon 9 with paying civilian passengers). I pick Musk.

SpaceX launches commercial radio satellite with reused Falcon 9

9:58 pm

Capitalism in space: SpaceX tonight successfully launched a Sirius-XM commercial radio satellite using its Falcon 9 rocket.

The first stage, making its third flight, successfully landed on the drone ship in the Atlantic. Note too that this launch took place only three days after SpaceX’s previous launch. Watching it take place, I was struck by how completely routine everything seemed. While rocketry will never be easy, SpaceX now makes it look so, and they do so because, unlike all other rocket companies, they did not stop upgrading and improving their rocket once it became somewhat reliable. Instead, they focused on making it more reliable than any rocket ever by making it reusable. That effort has now paid off, giving them a rocket that works like clockwork, practically every time.

The leaders in the 2021 launch race:

18 SpaceX
15 China
8 Russia
2 Rocket Lab
2 ULA

The U.S. now leads China 24 to 15 in the national rankings.

SpaceX successfully launches cargo Dragon to ISS

10:52 am

Capitalism in space: SpaceX today successfully launched a cargo Dragon to ISS.

The first stage booster successfully landed on its drone ship in the Atlantic Ocean.

This Falcon 9 rocket and Dragon capsule were entirely new, making their first flights. This was the first new Falcon 9 to fly since November 2020, with sixteen launches during that period using reused boosters exclusively.

In fact, since November 2020 SpaceX has completed a total of 21 launches, all done in less than seven months. Moreover, the company has scheduled 34 (!) more launches through the rest of the year. If they achieve this ambitious schedule, they will complete 51 launches in ’21, more than doubling their previous annual record of 25 set last year. With all other American companies added in, there will be a good chance the United States launch total could exceed 70, breaking the country’s own annual launch record set in 1966 at the height of the first space race.

The leaders in the 2021 launch race:

17 SpaceX
15 China
8 Russia
2 Rocket Lab
2 ULA

The U.S. now leads China 23 to 15 in the national rankings.

Axiom strikes tourist deal with SpaceX for three more flights

9:48 am

Capitalism in space: Axiom today announced that it had signed a deal with SpaceX to use its Dragon capsule and Falcon 9 rocket to launch three more manned tourist missions following the first now scheduled for January.

Ax-1, Axiom’s historic first private ISS mission, has already been approved by NASA and targeted for launch to the ISS no earlier than Jan. 2022, also aboard Dragon as a result of a deal the companies signed in March 2020. Axiom last week revealed legendary astronaut Peggy Whitson and champion GT racer John Shoffner would serve as commander and pilot on its proposed Ax-2 mission – now confirmed to be a Dragon flight.

So, too, are Ax-3 and Ax-4.

Other than Whitson and Shoffner, the company has not revealed who will fly on those three additional flights. That it made this deal however strongly suggests that it has ample demand for seats and will fill those capsules with no problem.

The press release also reiterates the company’s space station plans. They will begin attaching their own modules to ISS in ’24, with the goal of detaching from the station in ’28 and operating as an independent entirely private station thereafter.

Pentagon getting serious of hauling cargo with Starship

9:13 am

Capitalism in space: In the budget proposal submitted by the Biden administration the Pentagon included a request for $47.9 million to help develop the infrastructure it will need to use SpaceX’s Starship rocket as a method for transporting cargo point-to-point on Earth.

“The Department of the Air Force seeks to leverage the current multi-billion dollar commercial investment to develop the largest rockets ever, and with full reusability to develop and test the capability to leverage a commercial rocket to deliver AF cargo anywhere on the Earth in less than one hour, with a 100-ton capacity,” the document states.

Although this does not refer to Starship by name, this is the only vehicle under development in the world with this kind of capability. The Air Force does not intend to invest directly into the vehicle’s development, the document says. However, it proposes to fund science and technology needed to interface with the Starship vehicle so that the Air Force might leverage its capabilities.

Clearly, some Air Force officials are intrigued by the possibility of launching 100 tons of cargo from the United States and having the ability to land it anywhere in the world about an hour later.

The proposal is calling for a fourfold increase in funding for this work, as the Air Force is already spending slightly less than $10 million this year on this work.

The bottom line is that it appears SpaceX already has at least one real customer for its giant rocket. And if the military is that interested now, it likely means many more private customers are beginning to line up.

SpaceX barrelling like a juggernaut toward first Starship/Superheavy orbital flight this year

9:36 am

Starship #15 about to land
Starship prototype #15 about to land, May 5, 2021

A series of articles at Teslarati in the past two days suggest strongly that the next Starship flight will be on top of a Superheavy first stage, and will likely be the first near orbital flight from Texas around the globe to splashdown softly in the Pacific Ocean northeast of Hawaii.

And it will likely happen this year!

First there was the report from locals in the McGregor, Texas, area indicating that SpaceX has completed a full duration launch burn of a Raptor engine.

A local resident and unofficial SpaceX observer has reported hearing a test of one of Starship’s Raptor engines that lasted more than five minutes at the company’s McGregor, Texas development facilities.

If accurate, it could be the longest static fire of a Starship engine that SpaceX has ever completed in the two years since full-scale Raptor testing first began. Whether it was successful or not, a five or six-minute static fire would also confirm that SpaceX is well into the process of qualifying Raptor for Starship’s first orbital launch attempts.

This burn is somewhat longer than the engine burns during the Starship test hops, and approaches the burn time required for Superheavy during a launch.

Next there was the report describing the newest known engine configurations SpaceX is planning for Superheavy itself, with the first version possibly having 29 engines and a future more powerful version sporting 32.

China creates company to build mega-satellite constellation

9:12 am

The new colonial movement: Late last month China officially created a company to build its own mega-satellite constellation, consisting of 13,000 satellites to provide internet access globally, to compete with the commercial constellations being built by SpaceX, OneWeb, and (someday) Amazon.

Spectrum allocation filings submitted to the International Telecommunication Union (ITU) by China in September last year revealed plans to construct two similarly named “GW” [Guowang] low Earth orbit constellations totaling 12,992 satellites. The filings indicate plans for GW to consist of sub-constellations ranging from 500-1,145 kilometers in altitude with inclinations between 30-85 degrees. The satellites would operate across a range of frequency bands.

Currently no details have been released on the contractors to be involved in the constellation. Notably the China Satellite Network Group will exist independent from and parallel to China’s main space contractors, the China Aerospace Science and Technology Corp. (CASC), and the China Aerospace Science and Industry Corporation (CASIC).

The apparent independence of China Satellite Network Group from CASC and CASIC indicates that other actors, such as other state-owned enterprises and commercial sector space companies could be involved in the construction of the constellation.

Not only does the creation of this company suggest a power-struggle within China’s government, it illustrates the intensifying competition internationally over space. While commercial satellite constellations like SpaceX and OneWeb will be able to provide their services to China, they will also be outside the control of that nation’s dictatorship. If their citizens use them they will have free access to information, something that China’s leaders refuse to allow.

Thus, the political decision in China to build their own constellation. It will also give China the ability to exert its influence worldwide by offering an alternative to the commercial western constellations, one that other dictators can control as well.

Expect more whining from astronomers about how this constellation of satellites will add to their woes. Instead of whining, might they finally decide to at last consider building in-space telescopes, where there is no atmosphere to fog their view and no satellites blocking their vision?

Starship prototype #15 removed from launchpad; likely not to fly again

8:57 am

Capitalism in space: SpaceX engineers have removed Starship prototype #15, the first to successfully land after a test flight, from the launchpad and rolled back towards their assembly building.

They had already removed its three Raptor engines and landing legs for inspection, but taking the ship off the launchpad strongly suggests the company has decided to not fly it again.

The immediate assumption is that they will now fly prototype #16, built and ready for launch. The article however speculates something far more intriguing:

There’s a limited possibility that Starship SN16 – all but finished – could be sent to the launch site instead of heading straight to the scrapyard, but any testing would necessarily delay orbital pad construction and any flight activity would likely have to expend SN16 in the ocean rather than risk a land landing.

Ultimately, it’s looking more and more likely that SpaceX would rather go all-in on Starship’s inaugural orbital launch attempt, even if that means little to no ground or flight test availability for a few months.

Prototype #20 had been assigned that for that first near-orbital flight. Does this mean SpaceX has decided abandon #16 through #19 and to go straight to that orbital flight? To do this would also mean they have decided to forego any separate testing of Superheavy, and will instead fly it the first time with a Starship upper stage attached. It would also be the only possible way they could meet their July target date for that orbital flight.

If #16 does not move immediately to the launchpad and there are no Starship test flights for the next month or so, it will tell us that this is likely their plan.

SpaceX successfully launches another 60 Starlink satellites

12:15 pm

Capitalism in space: SpaceX today successfully used its Falcon 9 rocket to place another sixty Starlink satellites in orbit, bringing that constellation to over 1,700 in orbit.

The first stage was making its second flight, and landed successfully on the drone ship in the Atlantic. Both fairings were reused, with one making a record fifth flight. Though the rocket has not yet deployed the satellites as I write this, it is expected in about a half hour and based on past history, should proceed with no problems. If there is an issue I will report it immediately.

The leaders in the 2021 launch race:

16 SpaceX
13 China
7 Russia
2 Rocket Lab
2 ULA

The U.S. now leads China 22 to 13 in the national rankings.
