SpaceX wins competition to build Artemis manned lunar lander, using Starship

1:58 pm

December 2020

Capitalism in space: NASA has just announced that it has chosen SpaceX to build the Artemis manned lunar lander, using Starship.

The award, a $2.9 billion fixed price contract, also requires SpaceX to complete an unmanned demo lunar landing with Starship that also returns to Earth, before it lands NASA astronauts on the Moon. The contract also still retains the goal to get this to happen by 2024, though NASA official emphasized that they will only launch when ready.

After these flights the agency says it will open bidding again to the entire industry, which means that others are now being challenged to come up with something that can beat SpaceX in the future.

Nonetheless, the contract award was a surprise, as NASA originally intended to pick two teams to provide redundancy and encourage competition. Instead, the agency completely bypassed lunar landers proposed by Dynetics and a team led by Blue Origin that included Lockheed Martin and Draper.

Even more significantly, though NASA explained in the telecon that they still plan to use SLS and Orion to bring astronauts to Gateway, who will then be picked up by Starship for the landing, this decision is a major rejection of the Space Launch System (SLS), since Starship will not use it to get to the Moon, while the other two landers required it.

In fact, this decision practically makes SLS unnecessary in the Artemis program, as NASA has also awarded SpaceX the contract for supplying cargo to the Lunar Gateway station as well as launching its first two modules, using Dragon capsules and Falcon Heavy. SLS is still slated to launch Orion to Gateway, but Starship can replace Orion as well, since Starship is being designed to carry people from Earth to the Moon. This makes SLS and Orion essentially unneeded, easily abandoned once Starship starts flying.

NASA’s decision also means the Biden administration is willing to use its clout to push for Starship over SLS in Congress, which has favored SLS for years because of the pork it brings to their states and congressional districts. They apparently think that Congress is now ready to risk the end of SLS if it comes with a new program that actually accomplishes something. These developments firmly confirm my sense from February that the political winds are bending away from SLS.

This decision is also a major blow to Blue Origin and the older big space companies that Jeff Bezos’ company partnered with. Their dependence on the very costly and cumbersome SLS rocket meant that their ability to launch on a schedule and cost desired by NASA was severely limited. NASA looked at the numbers, and decided the time was right to go with a more radical system. As was noted by one NASA official during the press teleconference, “NASA is now more open to innovation.”

Based on the details announced during the announcement, NASA was especially drawn to Starship’s payload capability to bring a large payload to the Moon, at the same time it brings humans there as well. It also appears SpaceX’s recent track record of success also added weight to their bid.

SpaceX raises another $1.16 billion in private capital

9:25 am

Capitalism in space: In a regulatory filing yesterday SpaceX revealed that it raised another $1.16 billion in private investment capital in just the past two months.

This follows two other recent financing rounds since August of last year in which SpaceX raised almost $3 billion. That makes $4 billion raised in eight months. All told, I think this brings the total private investment capital SpaceX has raised in the past two years to approximately $6 billion, all for building both the Starlink satellite constellation and the Starship/Superheavy rocket.

Not only does this give SpaceX ample cash to build both, it signals the growing faith big money investors have in the company’s plans. They have bought into Elon Musk’s dreams because he has proven that his dreams deliver, not only in exciting space ventures but in profits.

This fund-raising success also tells us that even if Starship does not reach orbit before SLS, it will very soon eclipse it entirely. It has the money now to get built, and the way SpaceX builds things, it will get built fast.

SpaceX’s Falcon Heavy wins launch contract for VIPER lunar rover

9:39 am

Capitalism in space: Astrobotic, the company building the lander to place NASA’s VIPER lunar rover on the Moon, has picked SpaceX’s Falcon Heavy as the rocket to launch the package.

This mission is part of a fleet of landers being sent to the Moon in the next two years, as part of NASA’s Commercial Lunar Payload Services (CLPS) program to hire private companies to do this rather than NASA.

Intuitive Machines, which won CLPS task orders for two lander missions, will launch each on Falcon 9 vehicles late this year and in 2022. Masten Space Systems selected SpaceX to provide launch services for its XL-1 lander mission, which won a CLPS award for a late 2022 mission.

Astrobotic will launch its first CLPS mission, a smaller lunar lander called Peregrine, on the inaugural launch of United Launch Alliance’s Vulcan Centaur currently scheduled for late this year. Firefly Aerospace, which won the most recent CLPS award in January, has not selected a launch provider yet for its Blue Ghost lander, but noted the lander is too large to launch on the company’s own Alpha rocket.

That’s five American lunar missions, all built and owned by private companies. Nor will these be the only unmanned lunar missions, when you include the UAE rover targeted for a ’22 launch, along with additional planned Indian, Chinese, and Russian missions. Almost all are aimed at the Moon’s south polar regions.

It is going to get both crowded and busy on the Moon in the next few years.

UAE hires Japanese company as partner for its ’22 lunar rover mission

9:34 am

Capitalism in space: The United Arab Emirates (UAE) has chosen the private Japanese company Ispace to provide the lander bringing its Rashid rover to the Moon in 2022.

ispace’s 240 kg lander is 2.3 meters tall and 2.6 meters wide. It will be launched by SpaceX, Elon Musk’s rocket company, on a Falcon 9 rocket. Once the iSpace lander is placed in the Earth’s orbit, it will travel to the moon on its own, land and unload the rover.

The lander will use solar panels for power, which will also allow the rover to communicate with Earth. It will also carry a solid-state battery made by NGK Spark Plug, which intends to examine its battery’s lunar performance.

This UAE project is similar but a step up from its Al-Amal Mars orbiter. In that case UAE used its money to have the orbiter mostly built by U.S. universities as they taught UAE’s students how to do it. In this case, UAE engineers appear to be building the rover itself, with the purchased help of others to provide the lander..

Starship #11 debris fuels environmentalist opposition

12:04 pm

They’re coming for you next: The debris that fell as far as five and a half miles away when SpaceX’s Starship #11 prototype exploded just before landing on March 30th has increased the already vocal opposition from various environmentalist activists of the space project.

Environmental organizations such as the Sierra Club, the Friends of Wildlife Corridor, and concerned citizens in the environmental research field have expressed their dissent about the SpaceX activities at Boca Chica.

Chris Sandoval, a science teacher in Brownsville with degrees in Wildlife and Fisheries and Ecotoxicology, has put forth a research paper explaining the possible effects of SpaceX activity in the surrounding natural habitats and economic consequences as a result of their expansion in the region.

Sandoval says research would show that contamination from rocket fluids would harm wildlife in the surrounding area. “Contaminants such as those of hydrocarbons are able to kill aquatic life, both vertebrate and invertebrate, at very low concentrations, especially when it’s in a semi-enclosed area as the Lagunas are,” explained Sandoval.

And yet, none of these claims seem to apply to the government-run spaceports in Florida and California, both of which are also surrounded by wildlife refuges. Why is that? Why do these environmentalists have a particular opposition to the spaceport of this private company, but none or little opposition to the government’s? Could it be that what they really oppose is private enterprise, and are using the environment as a tool to destroy it?

I should add, according to the U.S. Fish and Wildlife Service that manages this refuge, SpaceX has been working closely with them on mitigating the damage, which in the end I suspect will be quite minimal. The ecology is far stronger than these environmentalist like to portray it. What SpaceX did hardly compares to the damage a hurricane would cause, and that is not an unusual event at this Gulf coast location.

Whether this environmental opposition to SpaceX will result in any major delays or obstacles remains to be seen. Under a Trump administration I would not be too concerned. Under today’s Democratic Party Biden administration, who knows? The tendency of Democrats is to regulate, and to use their power to squeeze others. So far that has not yet happened aggressively in connection to SpaceX, though there have been signs that the Biden administration is interested in increasing the regulatory roadblocks SpaceX must face. We will only have to wait and see.

Above all this increases the urgency for SpaceX to shift as soon as possible its Starship and Super Heavy test flights to the two oil-rigs it purchased and are refitting as floating launch and landing platforms. Once the bulk of those test flights are far away, out in the ocean, the political clout of these protesters will be minimized.

Starship and Super Heavy update

10:09 am

Link here. The fifteenth Starship prototype has now been moved to its launchpad, which you can see here, while further work continues on Starship prototypes #16-20, the first Super Heavy prototypes, #1 and #2, and the orbital launchpad.

Starship #15 sports many changes in design from #11, and is expected to do its first test flight sometime in the coming weeks. As for the first Super Heavy prototype, it will be used to test some ground operations as well as the prototype itself, on the ground. Prototype #2 will hopefully make the first Super Heavy hop.

The construction of a full orbital launchpad lends great weight to SpaceX’s goal of making the first orbital flight before the end of the year.

Meanwhile, SpaceX has likely tightened security at this Boca Chica facility after a youtuber sneaked onto the site recently and posted video of himself wandering around the base of Starship #11, unmolested. He has since removed that video, but another youtuber grabbed it and has re-posted it for you to watch.

SpaceX successfully launches another sixty Starlink satellites

9:48 am

Falcon 9 today, with booster on 7th flight

SpaceX this morning successfully launched another 60 Starlink satellites, bringing the total number in orbit to more than 1,500.

The first stage, on its seventh flight, successfully landed on the drone ship. During SpaceX’s live stream they noted that every launch by the company this year has used a previously flown first stage. Both fairings on this flight were also reused.

The leaders in the 2021 launch race:

10 SpaceX
7 China
5 Russia
2 Rocket Lab

The U.S. now leads China 14 to 7 in the national rankings.

I have embedded SpaceX’s live stream below the fold. Because of the clear weather this was a particularly beautiful launch. The video during the landing of the first stage was especially spectacular, with the camera on the booster showing the entire landing.

SpaceX’s decision to build launchpad with Starship tanks proves the rocket will be cheapest ever built

10:10 am

Capitalism in space: The decision by SpaceX’s to build the tank farm for its Starship/Super Heavy launchpad at Boca Chica using Starship tanks, rather than inexpensive off-the-shelf storage tanks, strongly suggests that the company’s manufacturing facility for building those tanks makes them very inexpensive, and also suggests that the final rocket will be as cheap to launch as SpaceX has promised.

SpaceX is effectively taking identical rocket parts, slightly tweaking a handful of those parts, and turning what could have been a rocket into a propellant storage tank. This is significant because relative to all other rockets in history, even including SpaceX’s own Falcon 9 and Heavy, building storage tanks with unchanged rocket parts on a rocket assembly line would be roughly akin to hiring Vincent van Gogh to paint lane lines.

Ever since Elon Musk made the radical decision to switch from composite structures to stainless steel, Starship has always aimed to be radically different than any large rocket before it. Crucially, by using commodity steel, the CEO imagined SpaceX would be able to build Starships fairly easily and for pennies on the dollar next to even SpaceX’s exceptionally affordable Falcon 9. In the last 18 months, it’s become apparent that SpaceX has built a factory capable of churning out one or two massive steel rockets per month and is willing to consign at least four or five of those Starship prototypes to all-but-guaranteed failures for the sake of data-gathering and iterative improvement.

Technically, the most logical conclusion would be that Musk was right and that SpaceX has quickly developed the ability to build steel rockets larger than any other launch vehicle on Earth for perhaps just $5M or less apiece.

The analysis at the link is detailed and worth reading. If correct, this decision by SpaceX proves that Starship and Super Heavy will be the cheapest rocket ever flown, even though it will be the largest ever flown, and also completely reusable.

Methane tank leak caused Starship #11 failure

9:24 am

Capitalism in space: According to Elon Musk, a small leak of methane from one tank caused the failure of the eleventh Starship prototype. From Musk’s tweet:

Ascent phase, transition to horizontal & control during free fall were good.

A (relatively) small CH4 leak led to fire on engine 2 & fried part of avionics, causing hard start attempting landing burn in CH4 turbopump.

This is getting fixed 6 ways to Sunday.

Meanwhile, prototype #15 is getting prepped for rollout to the launchpad (Numbers 12-14 were scrapped), and the first prototype of first stage Super Heavy is being assembled to testing. It is presently unclear when either will take place, though the company still has a target date of July for its first orbital launch. According to Musk, the first orbital prototypes of Starship will be those numbered 20 or higher.

“Those ships will be orbit-capable with heat shield & stage separation system,” Musk tweeted. “Ascent success probability is high. However, SN20+ vehicles will probably need many flight attempts to survive Mach 25 entry heating & land intact.”

Knowing those first orbital ships will likely not land properly raises the question as to where they will be aimed to come down. SpaceX now owns two retired floating oil platforms, and is preparing them for use by Starship/Super Heavy. It could very well be that test flights of prototype #20+ will take place to and from those pads, out in the ocean, so as to minimize any risk to populated areas. Doing so will also allow SpaceX to hone its procedures for moving these big spaceships to and from the platforms.

Resilience successfully moves from one ISS docking port to another

4:29 am

With four astronauts on board the Dragon capsule Resilience tonight successfully undocked from one docking port on ISS and redocked to a different port.

This was the first time an American spacecraft had accomplished this task. It was necessary to clear the docking port that the next Dragon capsule, Endeavour, will use to bring its crew to ISS, presently set for launch on April 22nd.

Russian astronauts have piloted Soyuz spacecraft between different ports numerous times, both on ISS and on Russia’s earlier space stations. Tonight’s transfer by Resilience however was done entirely on autopilot. The American astronauts could have taken over manually at any time, but the spacecraft did the entire maneuver on its own.

There is a certain irony in how the Russians have always done this maneuver, manually, and how Resilience did this, without any human intervention. From the 1960s through the entire space shuttle program Americans and all its astronauts strongly demanded that their spacecraft be piloted, by the humans on board, rather than being controlled by software or ground control. The Russians instead insisted, at least initially, that while their astronauts had the capability of doing all maneuvers manually, their software or mission control should run things. This difference seemed to nicely symbolize the down-up nature of America versus the top-down culture of Russia.

Things are now reversed. I wonder if that tells us anything about the two cultures today.

Falcon 9 upper stage debris lands on Washington farm

9:57 am

Falcon 9 helium pressure tank
Click for full image.

When a Falcon 9 upper stage broke up over the Pacific northwest last week apparently one of its interior helium pressure tanks, used to help push the fuel or oxidizer from the larger tank during launch, fell on a Washington farm and has since been recovered.

The image to the right is that tank, in what appears to be remarkable shape. From the article:

Composite-overwrapped pressure vessels, or COPVs, are standard components in Falcon 9 rockets. They’re designed to hold the helium gas that’s used to pressurize propellant tanks. COPVs are likely candidates to survive re-entry because they’re relatively lightweight and heat-resistant.

The tank has been returned to SpaceX, which I am sure is going to be very interested in studying its condition very thoroughly.

Industry group representing big tech demands Starlink be blocked in India

9:08 am

They’re coming for you next: An industry group representing a number of big tech companies like Amazon and Google has written India’s governmental agencies that regulate broadband and space and demanded that they block SpaceX’s Starlink internet service in India.

An industry body representing the likes of Amazon, Hughes, Google, Microsoft and Facebook has written to the Telecom Regulatory Authority of India (Trai) and the Indian Space Research Organisation (Isro) asking them to stop SpaceX from pre-selling the beta version of its Starlink satellite internet services in India. It claimed SpaceX didn’t have licence or authorisation from the government to offer such services in the country. “We request you to urgently intervene to protect fair competition and adherence to existing policy and regulatory norms,” Broadband India Forum president TV Ramachandran said in the letters, seen by ET.

I could have filed this story under my series, “Today’s Blacklisted Americans”. These big tech companies have made it very clear in numerous earlier stories that they do not believe in competition or free speech. They are now demonstrating it again in India. Both Amazon and Hughes are direct competitors with Starlink. Neither also has a product that can compete with it (Amazon appears years from deploying its system and Hughes’ system has latency issues that make it much slower than Starlink). So, they team up with their leftist buddies Google, Microsoft, and Facebook to demand the Indian government do their dirty work for them, shutting down their competition.

It is unlikely that India’s Modi government, which is very much in favor of private enterprise, will do what these thugs want, but you never know. Politicians are like whores, they do what you pay them. If India does move to block SpaceX however I also expect there to be an outcry in that country, as it has many rural areas that can only be served by the kind of service Starlink is offering.

FAA says it will “lead” investigation into Starship #11 crash yesterday

9:44 am

They’re coming for you next: The Federal Aviation Administration (FAA) announced today that it will “oversee” the investigation into the crash at landing yesterday by SpaceX’s eleventh Starship prototype.

The Federal Aviation Administration, which had an inspector at SpaceX’s facilities to observe the test flight, said in a statement that the FAA will oversee the company’s investigation into the “prototype mishap.” The FAA has conducted similar mishap investigations after previous Starship test flights. “The [Starship] vehicle experienced an anomaly during the landing phase of the flight resulting in loss of the vehicle,” an FAA spokesperson said. “The FAA will approve the final mishap investigation report and any corrective actions SpaceX must take before return to flight is authorized.”

The FAA noted that it will also work with SpaceX to identify reports of light debris in the area, saying that there have yet to be any reported injuries or damaged to public property.

What will really go on here is that an FAA official will observe closely as SpaceX conducts the investigation. That official might have some background in space engineering, but he or she will be completely unprepared to actually lead the investigation. Thus in the end the FAA will really only be able to rubber stamp SpaceX’s conclusions, though it might as all governments do, demand its own pound of flesh before issuing that stamp.

Up to now the FAA has tried very hard to work with the new commercial space companies, especially SpaceX, doing as little as it can to impede their progress. There are strong signs however that this might now change with the Democrats in control of the White House and Congress. If so, expect the FAA to cause SpaceX some grief during this investigation, grief that could significantly delay further test flights.

Last two passengers on 1st entirely private manned spaceflight revealed

9:17 am

Capitalism in space: The last two passengers for the first entirely private commercial manned spaceflight, dubbed Inspiration4 and paid for by businessman Jared Isaacman, were announced yesterday, along with a launch date no earlier than September 15, 2021.

Isaacman bought the mission partly to fly in space, but also to raise money for St. Judes Children’s Research Hospital. Both Isaacman and Haley Arceneaux, a former St. Judes cancer patient, will fly. Their two new crew members are both experienced in aviation or spaceflight operations, though neither is a professional astronaut with any training in that field.

[Sian] Proctor describes herself as a scientist turned artist and an “analog astronaut” where people live in environments to simulate long-duration spaceflight. She has done four analog missions including NASA’s Hawai’i Space Exploration Analog and Simulation (HI-SEAS) Habitat to simulate a trip to Mars. She is a pilot, scuba diver, “and loves geoexploring our world.” Born in Guam while her father was working at a NASA tracking station there during the Apollo program, she has a B.S. in environmental science, an M.S. in geology, and a Ph.D. in Curriculum and Instruction: Science Education. She was a finalist in NASA’s 2009 astronaut selection.

While a U.S. Space Camp counselor, [Chris] Sembroski conducted simulated space shuttle missions and supported STEM-based education. He served in the Air Force maintaining a fleet of Minuteman III ICBMs and served in Iraq. After leaving the Air Force in 2007, he earned a B.S. in Professional Aeronautics from Embry-Riddle Aeronautical University. He now works for the aerospace industry in Seattle, although he did not specify what company.

Their spacecraft will be Resilience, the Dragon capsule that flew the first operational manned commercial crew to ISS, and is presently docked to the station. For the Inspiration4 flight however SpaceX is going to install a large domed window at the capsule’s nose, replacing the docking port that will not be needed.

Congress taking aim at SpaceX and Starship testing

9:55 am

They’re coming for you next: The Democratic Party leaders on the House committee that normally does not overseer the FAA’s commercial space office have now raised their concerns about the recent test flights of SpaceX’s new rocket, Starship, in particular demanding an investigation into the flight of prototype #8, which the FAA claims had occurred despite one FAA issue.

The latest version of SpaceX’s FAA launch license for the Starship suborbital test flight program, issued March 12, allows those test flights to take place “only when an FAA Safety Inspector is present at SpaceX’s Boca Chica launch and landing site.”

The change stemmed from an investigation into SpaceX’s violation of that launch license during the SN8 test flight in December. SpaceX proceeded with the flight despite the FAA determining that the flight profile exceeded the maximum allowed risk to the uninvolved public for “far field blast overpressure” in the event of an explosion. While the SN8 vehicle exploded upon landing, there were no reports of damage outside of the SpaceX test site.

FAA directed SpaceX to investigate the incident, delaying the flight of the next Starship prototype, SN9. That investigation included “a comprehensive review of the company’s safety culture, operational decision-making and process discipline,” the FAA said in a Feb. 2 statement.

The FAA cleared SpaceX to proceed with launches, with SN9 and SN10 launching and landing — and both exploding upon or shortly after landing — on Feb. 2 and March 3, respectively. Neither caused any damage outside of the SpaceX test site.

The FAA’s response to SpaceX’s launch license violation, including the lack of any penalties beyond the investigation, prompted criticism from two key members of Congress. In a March 25 letter to FAA Administrator Steve Dickson, Reps. Peter DeFazio (D-Ore.) and Rick Larsen (D-Wash.) sought to “register our concerns” with the incident. DeFazio is chair of the House Transportation Committee and Larsen the chair of its aviation subcommittee.

Much of these claims about the flight of prototype #8 however only appeared to become a significant concern after the Biden administration and the Democrats took power in January. Prior to that the FAA did not seem very troubled by that flight. In fact, the so called risk, “far field blast overpressure,” seems very contrived, especially since we have now had four Starship crashes on its landing pad, with no evident damage to even SpaceX’s own equipment nearby. Prior to January 20th the FAA was untroubled. After January 20th it suddenly became a deadly issue requiring stricter supervision by the government, though what that FAA inspector on sight can do or even know about the launch is baffling.

What these Democrats really don’t like is that someone is freely accomplishing something without their supervision or control. Like mobsters looking to exhort money, they are essentially telling SpaceX, “Nice business you got here. Sure would be a shame if something happened to it.”

With today’s fourth Starship crash, expect the Demorats in Congress now to swarm like flies over manure, all aimed at shutting down the most innovative new American space company in decades.

Starship prototype #11 crashes at landing

9:30 am

Capitalism in space: The fourth prototype of Starship to fly, #11, experienced another failure at landing early this morning, crashing onto its launchpad.

Below is SpaceX’s live feed, cued to begin at T-10 seconds. The video cuts out at T+5:49, just before landing. I have reviewed other live feeds and all that I can find so far were obscured by the cloudy conditions at landing.

Musk later tweeted the following:

‘At least the crater is in the right place!”

“Looks like engine 2 had issues on ascent & didn’t reach operating chamber pressure during landing burn, but, in theory, it wasn’t needed. Something significant happened shortly after landing burn start. Should know what it was once we can examine the bits later today.”

The next Starship prototype will be #15 (numbers 12-14 pulled when they decided to redesign based on the earlier flights).

SpaceX successfully launches another 60 Starlink satellites

8:51 am

SpaceX early today successfully used its Falcon 9 rocket to place another 60 Starlink satellites into orbit, bringing that constellation to over 1,300 satellites.

The first stage landed successfully, for the sixth time. Both fairing halves were also reused, and their recovery method has now been simplified:

SpaceX has recently appeared to adjust its fairing recovery strategy. The ships previously dedicated to fairing catch attempts, GO Ms. Chief and GO Ms. Tree, have been stripped of their nets and arms, a possible sign that dry fairing recoveries will no longer be attempted. Post-splashdown recovery has proven to be fairly successful, as recent missions frequently use fairing halves that have flown once if not multiple times before.

The leaders in the 2021 launch race:

9 SpaceX
6 China
4 Russia
2 Rocket Lab

Counting all launches, the U.S. now leads China 13 to 6 in the national rankings.

Another Starhip update: Static fire test today for #11

9:02 am

Link here. If the static fire goes well, the test flight for Starship prototype #11 should occur in the next few days, possibly as soon as tomorrow.

The article at the link also reviews the possible testing schedule for future prototypes. The next Starship prototype being prepared for flight, #15, will likely not fly next. Instead, it appears that SpaceX is gearing up to first begin tanking tests on its first Super Heavy prototype.

All could change of course depending on tests and flights and construction.

Update on SpaceX’s Super Heavy booster

9:55 am

Capitalism in space: According to this update on SpaceX’s Super Heavy booster, the first prototype is now stacked as two complete tank sections that only need to be welded together.

While a good amount of work still remains to weld the two halves together and connect their preinstalled plumbing and avionics runs, those tasks are largely marginal and will tweak the massive steel tower that’s now firmly in one piece. Comprised of 36 of the steel rings also used to assemble Starships, the first Super Heavy prototype – serial number BN1 – will stand roughly 67 meters (220 ft) tall from the top of its uppermost ring to the tail of its soon-to-be-installed Raptor engines.

At that height, Super Heavy BN1 is just 3 meters (~10 ft) shorter than an entire two-stage Falcon 9 or Falcon Heavy rocket – the second and third tallest operational rockets today. Of course, Super Heavy is just a booster and SpaceX says the rocket will stand at least 120m (~395 ft) tall with a Starship upper stage and spacecraft installed on top, easily making it the tallest (and likely heaviest) launch vehicle ever assembled.

The report also adds SpaceX’s confirmation that this prototype will never fly, but will be used solely for ground tests. It is the second prototype that will do the first short test hops, hopefully sometime this summer.

SpaceX & NASA agree to better coordinate their satellite constellations to avoid collisions

9:49 am

NASA announced yesterday that it has signed an agreement with SpaceX to better coordinate and share information about their their satellite constellations in order to avoid collisions and launch conflicts.

SpaceX has agreed its Starlink satellites will autonomously or manually maneuver to ensure the missions of NASA science satellites and other assets can operate uninterrupted from a collision avoidance perspective. Unless otherwise informed by SpaceX, NASA has agreed to not maneuver its assets in the event of a potential conjunction to ensure the parties do not inadvertently maneuver into one another.

Makes great sense. Not only will this help avoid damage to satellites from both entities, it commits NASA’s support of SpaceX’s Starlink.

SpaceX narrows Mars landing site for Starship to four prime locations

11:19 pm

The prime and secondary Martian landing sites for Starship

Capitalism in space: During this week’s 52nd Lunar and Planetary Science Conference, one poster [pdf] caught my eye as something significant. It was titled “SpaceX Starship Landing Sites on Mars.” The map to the right is figure 1 from that poster, annotated slightly by me based my earlier stories about SpaceX’s use of the high resolution camera on Mars Reconnaissance Orbiter (MRO) to research potential Martian landing sites for its Starship spacecraft. The stars indicate MRO images, most of which were described and linked to in my last major post about this SpaceX effort in November 2019.

The red spots covering some stars are the big story: SpaceX has narrowed its choice for its Starship landing site to four prime locations (indicated by the bright red spots) and three backup locations (indicated by the dark red spots). The images under the red spots numbered 2, 4, and 6 were linked to in my November 2019 post. The images under red spots marked by a “D” are earlier images taken by MRO when SpaceX was researching a potential Dragon landing site. The images under red spots labeled 1P and MRO are subsequent images taken by MRO since November 2019, with the 1P image previously linked to in a post in April 2020 entitled “The icy Phlegra Mountains: Mars’ future second city.”

The poster outlined why the prime candidate sites — PM1, EM16, AP1, and AP9 — were favored. For example, PM-1 in the Phlegra Mountains “…has the lowest latitude and elevation of the group, a clear association with LDAs [lobate debris aprons that resemble glacial features], well developed polygons, and has the highest SWIM [Subsurface Water Ice Mapping] score for geomorphic indicators of ice.”

EM 16 “…has a clear association with an LDA with nearby brain terrain and the strongest radar return for shallow ice and the highest combined SWIM score.”

AP1 “…appears to be the safest site and has a moderate combined SWIM score for ice.”

AP9 “…has the thickest ice from radar returns and geomorphology indicating shallow ice. It has the highest combined SWIM score for ice, but appears slightly rocky and rough.”

Below the fold are images, rotated, cropped, and reduced to post here, of the four primary landing sites, as well as links to the full images of all four plus the three back-up sites (AP8, EM15, and PM7).

Musk confirms goal of orbital Starship flight this year

Capitalism in space: Musk today confirmed the stories published earlier this week that SpaceX has a target goal of completing the first test orbital flight of Starship before the end of this year, possibly as early as July.

The only new news in the article is Musk’s confirmation. It does outline again the challenges SpaceX faces to meet this goal, recognizing that these dates are thus merely targets that almost certainly will not be met. It also recognizes that the targets tell us that development will continue to move forward swiftly, and that an orbital test flight is also likely not that far in the future.

Who wants to bet that a Starship/Super Heavy rocket reaches orbit before SLS? Right now the odds I’d say are about 50-50.

Starship update: Prototype #11 could fly tomorrow

9:09 am

Capitalism in space: According to this Starship update, the 11th Starship prototype is scheduled for its static fire dress rehearsal countdown today, with the possibility of its first flight as early as tomorrow.

This paragraph about SpaceX’s overall Starship program however is more significant:

Following SN11’s flight, SpaceX will move on to SN15, 16, and 17, alongside testing with Super Heavy prototypes BN1 and BN2, before shooting for an orbital launch with SN20 and BN3. In typical SpaceX-style, that orbital launch has an astonishing – and unlikely – “by July 1” target. At the very least, this target portrays SpaceX’s Starship drive to push the vehicle into operation.

The reason they are going directly from prototype #11 to #15 is because they scrapped #s 12, 13, and 14 after the flights of #9 and #10. They had learned enough, and those scrapped prototypes would not have taught them anything. Instead, they incorporated the learned changes to #15 and will fly that next.

The July 1st launch date is certainly overly optimistic. It also signals the company’s determination to try to get that first orbital flight off this year. Based on their pace, it would be foolish to dismiss this as a possibility.

It also signals what I think is an internal unstated goal within SpaceX to have Starship beat SLS into orbit. Nor would anyone be wise to consider that impossible. In fact, I consider it quite likely.

SpaceX launches another 60 Starlink satellites

9:10 am

Capitalism in space: SpaceX early this morning successfully launched another 60 Starlink satellites into orbit using its Falcon 9 rocket.

The company also successfully used a first stage for a record ninth time, landing it on its drone ship in the Atlantic. The booster did all nine flights in just over two years.

The 2021 launch race:

8 SpaceX
6 China
3 Russia
1 Rocket Lab
1 Virgin Orbit
1 Northrop Grumman
1 India

The U.S. now leads China 11 to 6 in the national rankings.

Space Force awards launch contracts (two each) to ULA and SpaceX

10:08 am

Capitalism in space: On March 9th the Space Force announced that it has awarded four new launch contracts, two each to ULA and SpaceX, for a total cost of just under $400 million, all to launch in ’23.

Under the task orders issued March 9, ULA and SpaceX will each launch two missions. ULA was awarded $225 million to launch and integrate the USSF-112 and USSF-87 missions on its Vulcan Centaur rockets while SpaceX was awarded $160 million to launch and integrate USSF-36 and launch NROL-69 on its Falcon 9 rockets.

Based on these numbers it appears ULA is charging about $113 million per launch for its new Vulcan Centaur rocket, while SpaceX is charging about $80 million using its Falcon 9.

For ULA, that is less that what it would charge using its Atlas 5 rocket, but not by much. For SpaceX this price is high, probably because the military might be demanding the company use new boosters for its launches.

These high prices for both are to me a sign of how little our federal government cares about saving any money for the taxpayer. While the competition brought on by SpaceX’s arrival is saving the military money, the way these contract awards are structured, with both ULA and SpaceX guaranteed to win them, neither company has an incentive to reduce its prices. Instead, they can overcharge and the military can do nothing about it.

In a more sane world the military would use the competition in the launch market to get an ever better deal. Instead, our federal government sees its budget as a blank check, and they are using it.

SpaceX successfully launches 60 more Starlink satellites

8:59 am

Capitalism in space: SpaceX last night successfully launched another sixty Starlink satellites, raising the total launched to 1,265, with more than a thousand operating.

The company also landed the Falcon 9’s first stage for the sixth time while reusing both fairings.

The 2021 launch race:

7 SpaceX
4 China
3 Russia
1 Rocket Lab
1 Virgin Orbit
1 Northrop Grumman
1 India

The U.S. now leads China 10 to 4 in the national rankings. In fact, SpaceX alone has as many launches as China and Russia combined.

Starship #11 moves to launchpad

4:00 pm

Capitalism in space: Less than a week since the flight and destruction of Starship prototype #10 post flight, SpaceX has now moved Starship #11 to the launchpad.

There is no firm word on when they will attempt to fly this prototype, but based on past history, they will likely do at least one static fire test this week and schedule the flight for next week. All will depend of course on weather and on the results of the static fire test. For example, with #10 they found they needed to replace one engine after the first static fire test.
