SpaceX successfully launches commercial radio satellite

1:32 pm

Capitalism in space: SpaceX today successfully launched a new commercial radio satellite for Siruis.

The first stage was making its seventh flight, the fifth in 2020. It successfully landed on the drone ship. The fairings were also both previously flown.

The leaders in the 2020 launch race:

33 China
24 SpaceX
13 Russia
6 ULA
5 Rocket Lab
5 Europe (Arianespace)

The U.S. now leads China 38 to 33 in the national rankings. The U.S. has also completed the most launches in a single year since 1968. Unlike 1968, all the launches this year were flown by private companies, either for commercial customers or for the government, with rockets owned by the companies. In 1968 almost all the launches were for the government, and the rockets were controlled by the government, even if built by private companies.

Note that this very successful year occurred during a year when many businesses were forced to shutdown due to the Wuhan panic. It appears many rocket companies decided this was not a reason to cease operations.

Indonesia & SpaceX considering launchsite there

8:26 am

Capitalism in space: Indonesia has been in discussions with SpaceX and Elon Musk about establishing a SpaceX launch site in that country.

President Joko Widodo discussed the idea with SpaceX founder Elon Musk during a phone call on Friday, the Coordinating Ministry for Maritime and Investment Affairs said in the statement. Musk intends to send a team to Indonesia in January to study partnership opportunities, it said.

Makes sense for Musk to consider such a move, especially if the U.S. and Texas governments start to turn the screws on his Boca Chica launch site. Furthermore, it is his intention to eventually launch Starship/Super Heavy from a floating launch platform. Establishing arrangements with other foreign nations for putting it in their waters gives the company more flexibility.

People always migrate toward freedom. For two hundred and fifty years, that meant they moved to the United States. This now is changing, as the U.S. culture is signaling its increased hostility to this most important founding principle. Expect more stories like this in the coming decades.

Breaking: Starship prototype #9 tips over inside assembly building

12:43 pm

It appears from the 24-hour live stream provided by LabPadre that the ninth Starship prototype tipped over inside the assembly building to rest against one wall. You can see it happen at about 8 seconds into the video below:

No word on whether anyone was hurt, nor any information about the cause. My guess is that it occurred during the operations to move this prototype to the launchpad.

UPDATE: It appears no one was hurt, but there is damage to the fins, which might also mean damage to the hull. This in turn might make it unsafe to fly this prototype, as the hull forms the walls of the methane/oxygen tanks.

The day has not been good for SpaceX. Earlier they had to scrub the launch of a commercial communications satellite at T-30 seconds for reasons that they did not provide. High altitude winds had delayed the launch an hour or so, but it appears this was not the reason. According to SpaceX’s website, “SpaceX is standing down from Friday’s launch attempt of the SXM-7 mission to perform additional ground system checkouts.” They are targeting Sunday for the next launch attempt.

Starship: Old-fashioned American know-how

11:39 am

Starship about 2 minutes into its flight

Yesterday’s truly epic first flight of SpaceX’s giant Starship rocket illustrated several truths that bear repeating, in clear and forceful language.

SpaceX succeeded because its company philosophy is open-minded, fearless, and thus free.

The open-mindedness culture comes from Elon Musk’s insistence that they never settle on any design if they can find a better way to do it. It is this approach that drives the company’s developmental process. The first Falcon 1 rocket made orbit, but despite that triumph Musk quickly abandoned it for the Falcon 9 when it was clear that it wasn’t powerful enough to garner enough satellite business.

The Falcon 9 that first launched in 2008 was a very different rocket from the Falcon 9 that launches today, as shown by the two pictures below. In the 2008 Falcon 9 the engines were configured differently and it had no legs. The modern Falcon 9 has landing legs, a different engine arrangement, and much of the innards have been redesigned to give the rocket more oomph.

Starship flies!

4:31 pm

Starship about 2 minutes into its flight

Capitalism in space: In a spectacular achievement, SpaceX’s eighth Starship prototype today completed 6:42 minute flight that appeared to go practically perfectly, until landing.

At that point it appeared the spacecraft’s last landing burn was insufficient to slow it down enough for landing, and it crashed. However, it crashed on its landing pad, meaning it had maneuvered its way back through the atmosphere exactly as planned.

Below the fold are screen captures from the flight, in sequence.

The flight left several impressions. First, this design is viable. Though we are still looking at a prototype, it is one that works.

Second, the ship appeared to lumber into space, almost slowly. This was partly an illusion because of its size. Nonetheless, it reminded me of the 747, which always flew magnificently but with what seemed like a measured attitude. Starship appeared similar.

Third, the systems for controlling the ship on its return through the atmosphere appeared to work as intended. Though SpaceX obviously has a lot more work to do to achieve an orbital return, they have made a magnificent start.

And they have gotten this far in only two years, for less than $2 billion. Compare that to NASA and Boeing and their SLS, which is half a decade behind schedule and will likely cost $30 billion once launched.

We should expect the ninth prototype to be on the launchpad within days, and the next test flight in no more than few weeks.

Original post:
——————-
Capitalism in space: SpaceX’s live stream is on, with a liftoff in six minutes. I have embedded below the fold the live stream for this first high altitude flight of SpaceX’s Starship.

The LabPadre live stream, to the right, shows that they have already proceeded through most of preliminary stages prior to liftoff.

If all goes right, this eighth prototype of Starship will go about 40,000 feet in the air, turn over and attempt to control its return belly side down, and then upright itself just before landing so it can complete a vertical landing like a Falcon 9 first stage. The company gives themselves a one in three chance of landing the spacecraft. SpaceX has also made it clear that their primary engineering goal on this flight is to test that return through the atmosphere, so that is the part of the flight they most need to succeed. Failing to land afterward but getting that data will make this test a complete success.

No matter what happens, the company has prototypes 9 through 15 waiting in the wings.

UPDATE: This post will remain at the top of the page until the flight occurs, or is scrubbed. Scroll down for new stories.

Starlink dark coating reduces reflectivity by half

9:23 am

Astronomers in Japan have now confirmed that the dark coating SpaceX has been putting on its more recent Starlink satellites has successfully reduced their reflectivity by half.

They looked at the satellites across a range of wavelengths.

Observations conducted from April to June 2020 revealed for the first time in the world that artificial satellites, whether coated or not, are more visible at longer wavelengths, and that the black coating can halve the level of surface reflectivity of satellites. Such surface treatment is expected to reduce the negative impacts on astronomical observations.

Knowing this detail will allow commercial satellite companies such as SpaceX to further refine their coatings to better hide their satellites from ground-based telescopes.

While good news, it doesn’t change the fundamental lesson that astronomers need to learn. They must move their telescopes off the Earth and into space. In the long run ground-based astronomy is a dead-end.

Musk confirms he has left California for Texas

11:43 pm

SpaceX founder Elon Musk today confirmed that he is selling his homes in California and is moving permanently to Texas.

Musk did not reveal whereabouts in the Lone Star State he has moved to. It’s also unclear whether he will purchase any property there, given that he stated earlier this year that he wants to rid himself of possessions and is only interesting in renting.

Over the summer, the Musk Foundation officially consolidated its headquarters in Austin – a city that also houses a Tesla assembly plant. However, Musk is also known to spend time in Boca Chica, on the southeast coast of the state, where there is a SpaceX facility.

For the time being, both Tesla and SpaceX remain headquartered in California. It is unclear whether Musk will officially move both businesses to Texas at a later date.

I expect that both Tesla and SpaceX in California will soon be leaving as well. Musk is shrewd however. He has been shifting both slowly from California in the past two years as he has found it increasingly impossible to deal with government officials there. Witness Starship for example. Two years ago it was to be built in the Port of Los Angeles. Now, with little fanfare all operations have moved to Texas.

Musk will leave slowly, so as to not stir a political hornet’s nest among the fascist legislators of California. They consider everything everyone owns as belonging really to them, and will not take kindly to any attempt of Musk to escape.

Launch abort for Starship high altitude flight

4:03 pm

Starship at T-1 second on launch pad
Screen capture from SpaceX live feed at T-1 second.
Click for LabPadre live stream.

The attempt today by SpaceX to fly its eighth prototype of Starship to 40,000 feet aborted at T-1 second, apparently because the rocket’s computers sensed something wrong and shut things down.

They have stood down for the day. At the moment there is no word on when they will try again, though they have a back up launch window for tomorrow, and SpaceX’s policy generally is to move forward quickly. The decision will likely depend on the reasons for the abort. I will bet they will try again tomorrow.

I have revised the the live feed post, removing references to today’s launch abort, since this information is now contained in this post. The live feed post however will remain at the top of the page.

SpaceX’s Starlink constellation wins $885 million in federal subsidies

8:44 am

Capitalism in space: In awarding $9.2 billion in subsidies to providers of rural high-speed internet to rural customers, the FCC gave $885 million of this allocation to SpaceX’s Starlink constellation.

SpaceX was not the biggest beneficiary, however.

Most of the RDOF Phase I subsidies are going to terrestrial broadband service providers, led by LTD Broadband with an award of $1.32 billion. CCO Holdings, a subsidiary of Charter Communications, is due to serve 1.05 million sites around the country, leading the list for that metric.

The FCC said 85% of the 5.2 million sites to be served would get gigabit-speed broadband. SpaceX is due to serve nearly 643,000 sites with download speeds of 100 megabits per second or more.

Regardless of its good intentions, this distribution of federal cash sickens me. These companies don’t need it to do what they are doing, and are all sure to make plenty of profit without it. The federal government meanwhile is trillions in debt. It has to print money to give this away, something that is not going to go well in the long run.

Weather delays Starship hop to December 8th; Musk arrives in Boca Chica

9:38 am

Starship on launch pad
Click for LabPadre live stream from which this still was captured.

Capitalism in space: Weather issues have delayed the first big hop of the eighth Starship prototype so that it is now scheduled for no earlier than tomorrow, December 8th.

That Elon Musk arrived in Boca Chica late on December 5th strongly suggests however the hop will finally happen this week, after several weeks of delays.

With Musk himself now on the ground in Texas to (presumably) oversee Starship SN8’s debut, the odds of launch later this week are arguably much better. Having now spent more than 10 weeks at the launch pad, at least twice as long as any Starship preceding it, there’s no small chance that SN8 – the first prototype of its kind – is starting to be more of a nuisance than an asset. By all appearances, Starship SN9 – essentially a “refined” copy of SN8 – is practically ready for launch with SN10 perhaps just a week or two behind it.

It also appears they have lowered the top planned altitude of the hop from 50,000 feet to about 40,000 feet.

Musk had tweeted earlier that SpaceX planned to live stream the event, which would be spectacular as they almost certainly have cameras on the spacecraft. If they don’t the LabPadre live stream above will also be an option.

Falcon 9 launches Dragon freighter to ISS

Capitalism in space: SpaceX today successfully launched for the first time its upgraded Dragon freighter to ISS.

The first stage was flying its fourth flight, and successfully landed on the drone ship in the ocean. This was also SpaceX’s 100th successful launch of its Falcon 9 rocket, with about two-thirds of those flights using a used first stage.

In the cargo was also the first privately built equipment airlock, built by Nanoracks for its use in launching private payloads. This will supplement the Japanese equipment airlock on its Kibo module, both used to move equipment (not people) in and out ISS. Dragon will dock with ISS tomorrow.

NASA considering commercial communications satellites for Mars

9:10 am

Capitalism in space: NASA officials have revealed that they are considering hiring commercial communications companies to build and launch a communications network of satellites to support its Mars science missions.

In recent presentations to advisory committees, NASA officials have discussed the possibility of working with industry to place several satellites into orbit around Mars that would serve as relays for other missions, notably the proposed Mars Ice Mapper. Such satellites, they said, could greatly increase the amount of data missions can return to Earth and end reliance on aging science missions that also serve as data relays.

One proposal presented at those meetings features three satellites in equatorial orbits at altitudes of 6,000 kilometers. The satellites would be equipped with radio links for communicating with other spacecraft in orbit and on the surface as well as to and from Earth. The satellites may also include laser intersatellite links to allow them to communicate with each other.

Based on the number of missions ongoing and planned for Mars, the agency has recognized it needs to establish a dedicated system for communicating with those missions, rather than depending on the science orbiters they have in orbit. That they are looking to commercial companies to build this for them, with NASA acting merely as a customer, as an excellent sign that the agency has now completely accept this approach, as I recommended in Capitalism in Space, rather than acting as the big boss that controls everything.

Starship 9-mile-high flight now set for no earlier than December 4th

9:13 am

Starship on launch pad
Click for LabPadre live stream from which this still was captured.

Capitalism in space: SpaceX has now scheduled the first 9-mile-high flight of its 8th Starship prototype for either December 4th, 5th, or 6th.

On Wednesday, the Federal Aviation Administration issued a temporary flight restriction for SpaceX to conduct a Starship launch from its facility near Boca Chica Beach in South Texas. The notification allows the company to attempt a Starship hop on Friday, Saturday, or Sunday, between the hours of 9am EST (14:00 UTC) and 6pm EST (23:00 UTC) daily. SpaceX must still obtain a launch license from the FAA for this flight.

The company’s founder and chief engineer, Elon Musk, has said SpaceX will attempt to fly Starship to an altitude of 15km to demonstrate the performance of three Raptor engines over the course of several minutes. The company’s previous flights to about 150 meters, in August and September, used a single Raptor engine.

This higher flight profile will take Starship above nearly 90 percent of Earth’s atmosphere, which will allow the company to do several new tests: assess the performance of body flaps on Starship, transition from using propellant from the main fuel tanks to smaller ones used for landing burns, and test the vehicle’s ability to reorient itself for returning to the launch site.

Look closely at the screen capture of Starship above. Note how there is no launch tower at all, and that the launchpad is simply a platform on which the ship sits. This lack indicates two things. First, the ship’s large diameter gives it a much lower center of gravity compared to all other rockets. It doesn’t need the launch tower for support. This is why SpaceX can move it back and forth from the assembly building on the equivalent of a large flatbed truck.

Second, the lack illustrates SpaceX’s lean and mean engineering style. When this spacecraft finally launches to orbit on top of a Super Heavy first stage, it will certainly need a launch tower, not so much for support but to fuel it and allow access to and from while on the launchpad. None of this infrastructure however is needed now for the ongoing development work. Why waste money and time building it when they don’t yet know the exact specifications of the final rocket itself?

SpaceX is taking advantage of the first point to do the second, thus speeding development and lowering its cost.

Starship 50,000 ft hop now scheduled for Nov 30th

8:35 am

Capitalism in space: Having completed all preliminary static fire tests, SpaceX has now set November 30th as the target date for 50,000 foot high hop for its eighth Starship prototype.

SpaceX is understood to be conducting a Flight Readiness Review (FRR) for the test flight, with this final Static Fire test providing key data to the final go to proceed towards SN8’s big day.

Elon Musk has already calibrated public expectations on the expected outcome of SN8’s test, noting that “understanding exactly how the body flaps control pitch, yaw & roll during descent, such that the ship is positioned well to relight, flip & land, would be a big win.” As opposed to expecting SN8 to land feet first on the landing pad.

Musk’s point is important. The primary engineering goal for this first hop will be to find out whether they truly understand how to control and fly Starship. Their knowledge in this area is only computer based, and thus is very incomplete, and could very well be wrong, resulting in a failure that prevents a proper clean landing.

Such as failure however would actually be an engineering success, as it would give them the data needed to make later prototypes work. As for landing, they know how to do that already. Once they get the flying right, the landing should follow.

SpaceX has said it will live stream that hop. Should be a thrill to watch.

Regulators coming after SpaceX’s Boca Chica facility and Starship

9:05 am

Capitalism in space? New FAA documents suggest that government regulators are not happy with the rapid and spectacular development by SpaceX of its Super Heavy/Starship rocket at Boca Chica, Texas, and are eager to impose restrictions and delays.

The issue revolves around revisions to SpaceX’s original FAA approval for its work at Boca Chica because the company has switched from flying Falcon 9 and Falcon Heavy rockets to developing and flying Starship and Super Heavy. While the FAA has been cooperative in issuing the necessary revisions, other agencies have raised red flags.

But the most important document of the bunch is the written reevaluation signed by the FAA on May 22. The file spans 26 pages, was required for SpaceX to receive its suborbital launch license from the FAA on May 28, and incorporates concerns from state and federal environmental agencies.

In the reevaluation, the Texas Parks and Wildlife Department and the US Fish and Wildlife Service took issue with several aspects of SpaceX’s plans and ongoing activities. Those criticisms targeted the “fluid nature” of the company’s construction projects, excessive road closures to Boca Chica Beach (which Brownsville locals prize), around-the-clock work that may affect nocturnal threatened or endangered species, prototype explosions, and sprawling wildfires the company has triggered.

The FAA responded to each concern in the document, ultimately determining “there are no significant environmental changes, and that all pertinent conditions and requirements of the prior approval have been met or will be met” with SpaceX’s suborbital test-flight plans.

However, SpaceX does not yet have the FAA’s go-ahead to launch any Starships to orbit from Boca Chica.

In its replies to concerns noted by other agencies — some of which call for a new EIS [environmental impact statement], which could take years to complete (an eternity in Musk time) — the agency repeatedly noted it is working with SpaceX to draft an “environmental review” of those plans.

Should Joe Biden and the power-hungry and controlling Democrats take control of the executive branch of the federal government, expect the FAA’s desire to help SpaceX to quickly end.

The SpaceX fleet of Dragons

11:10 am

The first manned Dragon capsule on the launchpad
The first manned Dragon capsule, on the launchpad

Capitalism in space: During the post-launch press briefing after launch of its second manned Dragon mission on November 15, SpaceX CEO Gwynne Shotwell revealed the company’s plans to build and fly a fleet of Dragon cargo and crew capsules, and reuse them repeatedly over the coming years..

Specifically, Shotwell revealed that SpaceX intends to build three reusable Cargo Dragon 2 capsules, one of which is already completed and in Florida preparing for its December 2nd CRS-21 launch debut. On the crew side of things, SpaceX will build “three more” Crew Dragon capsules on top of the flight-proven Demo-2 and currently orbital Crew-1 capsules. It’s unclear if this means that the new Crew Dragon capsule flown on SpaceX’s January 2020 In-Flight Abort (IFA) test will be refurbished for additional flights.

Excluding IFA Crew Dragon capsule C205, SpaceX thus intends to operate a fleet of at least three Cargo Dragon 2 and five Crew Dragon capsules, representing eight reusable spacecraft each capable of at least five orbital missions.

She also hinted that the company has plans to fly its own missions, using these spacecraft, in addition to its contracted flights for NASA and the private company Axiom.

This private capability, which far exceeds anything ever built by NASA or any government worldwide, is entirely because Elon Musk had the freedom and the will to push for his particular vision. He had a bold idea, and with courage he pursued it.

Israeli fighter pilot to fly on Axiom’s first private Dragon launch in ’21

9:24 am

Capitalism in space: Axiom has revealed that an Israeli fighter pilot, Eytan Stibbe, will be the second passenger on on its first private Dragon launch to ISS in the fall of 2021.

Stibbe will be the second Israeli to fly in space, following Ilan Ramon, who died when the space shuttle Columbia broke up in 2003 during its return to Earth.

The Axiom AX-1 mission is scheduled to launch in the second half of 2021, which the company unveiled in a deal with SpaceX earlier this year. Astronaut Michael Lopez-Alegria, who previously worked for NASA and flew to space four times, will be the AX-1 mission commander, with Stibbe set to serve as a mission specialist.

AX-1 would be the first fully private mission to the International Space Station, with Lopez-Alegria and Stibbe flying with two other yet-to-be-named people.

The consistent rumors are that actor Tom Cruise and a movie director will be those other two passengers, but this is not confirmed.

It is important to emphasize that this space mission will be entirely private, with almost no involvement of the U.S. government other than providing coordination, the training of the astronauts, and the use of ISS. The rocket and spacecraft are SpaceX’s, purchased by the customer Axiom. Moreover, Axiom has plans to add its own private modules to ISS where future private space passengers will be housed, which will then reduce the government’s role and contribution even more.

And since this will be a private mission, it means the funds to fly it will come from its passengers, not the government. This also means that as long as there are customers, there will be no slow-down in future flights.

Resilience has docked with ISS

9:52 pm

SpaceX’s Resilience Dragon capsule successfully docked with ISS tonight.

They are in the process of checking the seal of the docking, and the opening of the hatch.

As much as I have been critical of Boeing in recent years, I truly hope they can get their management and engineering problems worked out so they can accomplish the same thing with their Starliner capsule. The competition with SpaceX will be healthy for both companies, the nation, and the future of the human race.

Falcon 9 launch on November 15, 2020 with four astronauts

Capitalism in space: SpaceX tonight successfully launched four astronauts to ISS on its Dragon capsule Resilience, using its Falcon 9 rocket.

They also recovered the first stage, landing it on its drone ship in the Atlantic. The routine manner in which SpaceX ran this launch is truly admirable. They make landing and reuse of the first stage so expected it is hard to believe that for fifty years rocket managers and engineers insisted it wasn’t doable.

They had one issue today, a failure of the capsule hatch to hold air pressure after closure. They calmly reopened the hatch, cleared the issue, added some lubricant, and closed the hatch, all in less than ten minutes.

Resilience will dock with ISS tomorrow evening.

Watch today’s launch of SpaceX’s Resilience manned capsule

10:06 am

According to a NASA report yesterday, the weather then stood at 50% for allowing a launch of four astronauts to ISS on SpaceX’s Resilience capsule tonight at 7:27 pm (Eastern).

That percentage was still reported this morning. Part of the issue is that SpaceX wants to recover the first stage, and the weather therefore not only has to be good in Florida, it has to be good in the Atlantic where the stage will come down.

NASA’s live coverage begins at 3:15 pm (Eastern). The link to that live stream is below the fold. As I write this at around noon (Eastern) it is simply NASA TV’s normal feed, which is essentially full time propaganda for NASA. After 3:15 pm it will switch to live coverage, which unfortunately will still be packed with pro-NASA propaganda, even though this launch is entirely being run by the private company SpaceX. NASA’s only part is that of a customer, with the ability to say “no” at any point. The rocket, the capsule, the launchpad, and the countdown, is operated completely by SpaceX and its employees.

I have also added the clean feed from NASA, which appears to carry little commentary or narration.

Most recent engine test on eighth Starship prototype had issues

8:52 am

Capitalism in space: The most recent engine test on November 12th of SpaceX’s eighth Starship prototype had a problem that will delay its planned 50,000 foot test hop.

The Starship SN8 vehicle performed its third brief “static fire” — a test in which engines are ignited while a rocket remains tethered to the ground — at SpaceX’s South Texas facility on Thursday, near the village of Boca Chica.

Shortly after the test, which several outside organizations webcast live, material could be seen apparently dripping from SN8’s base. This looked odd, and SpaceX founder and CEO Elon Musk soon confirmed that something off-nominal had happened. “We lost vehicle pneumatics. Reason unknown at present. Liquid oxygen header tank pressure is rising. Hopefully triggers burst disk to relieve pressure, otherwise it’s going to pop the cork,” Musk said via Twitter on Thursday night. (Burst disks are single-use devices that, like valves, seal off different sections or systems of a vehicle. They relieve pressure when they open, as Musk noted.)

The cause of the problem is unknown at the moment, Musk said in another Thursday tweet: “Maybe melted an engine preburner or fuel hot gas manifold. Whatever it is caused pneumatics loss. We need to design out this problem.”

The decision to pin down the cause and redesign things so it won’t happen again makes perfect sense, but it also means that the hop will not occur in the next week or so, as hoped for by the company. Expect a delay. Based on the pace that SpaceX works, that delay however should not be longer than one or two months.

Elon Musk gets contradictory COVID-19 test results

8:40 am

The uncertainty of science: Because SpaceX’s founder Elon Musk had had some minor cold-like symptoms, he decided to get tested for COVID-19, and discovered that after four tests, he still had no idea whether he had it or not.

The Tesla boss and fifth-richest man in the world had initially tweeted Thursday night that “Something extremely bogus is going on” regarding COVID-19 testing. “Two tests came back negative, two came back positive. Same machine, same test, same nurse.”

…Though Musk had initially tweeted that his symptoms were “nothing unusual” and those “of a typical cold,” he gave more detail Friday morning. “Mild sniffles & cough & slight fever past few days,” he told one Twitter user who asked how he was feeling. “Right now, no symptoms, although I did take NyQuil.”

First, the results tell us that the so-called surge going on in new coronavirus cases that is panicking our Democratic Party lords and masters might very well be bogus. At a minimum we should all be more skeptical of the numbers.

Second, assuming Musk does have COVID-19, his symptoms illustrate once again how relatively harmless the virus is to healthy people. In fact, no one seems to notice that of the numbers of people diagnosed with COVID-19 in the general populace, no one seems ever to die from it. Like the flu, they are sick for a week or so, and then recover.

Weather forces one day delay in launch of Resilience with four astronauts

9:26 pm

Because of high winds and ocean weather interfering with the recovery of the first stage, NASA and SpaceX today decided to delay the launch of SpaceX’s second manned Dragon mission, the capsule Resilience carrying four astronauts, to Sunday, November 15.

NASA and SpaceX are now targeting 7:27 p.m. EST Sunday, Nov. 15, for liftoff of the agency’s SpaceX Crew-1 mission to fly astronauts from Launch Complex 39A at NASA’s Kennedy Space Center in Florida to the International Space Station.

Teams moved the launch by one day because of onshore winds and to enable recovery of the first stage booster, which is planned to be reused to launch the Crew-2 mission next year. The booster is expected to land on the recovery ship about nine minutes after launch.

They now plan to dock with ISS at 11 am (eastern) on November 16th.

Update on continuing engine testing of Starship prototype #8

8:45 am

Link here. The article provides details on the on-going engine tests of SpaceX’s eighth prototype of its Starship reusuable upper stage.

As should be expected, the testing has not gone exactly as planned, though clear progress is being made, especially in the testing of the header tanks in the nosecone..

After several days of test windows come and gone and an aborted attempt on November 9th, Starship SN8 finally ignited one of its three Raptor engines, feeding the engine with liquid methane and oxygen stored in two separate header tanks. Oddly, a second or two after startup and ignition, Raptor’s usual exhaust plume was joined by a burst of shiny firework-like debris. A relatively normal five seconds later, the Raptor cut off, though the engine appeared to remain partially on fire for another ten or so seconds – also somewhat unusual.

It appears that fire was from nearby debris, not the engine itself.

Another engine test is likely later this week. The actual 50,000 foot hop will not happen until they have completed all these engine tests.

NASA officials gave approval Tuesday for SpaceX to begin regular crew rotation flights to the International Space Station with the launch of four astronauts set for Saturday from the Kennedy Space Center in Florida, signaling a transition from development to operations for the human-rated Dragon spacecraft.

Mission managers completed a two-day Flight Readiness Review Tuesday and issued a preliminary go-ahead for the launch of SpaceX’s Crew Dragon “Resilience” spacecraft Saturday at 7:49 p.m. EST (0049 GMT Sunday) with NASA commander Mike Hopkins, pilot Victor Glover, and mission specialists Shannon Walker and Soichi Noguchi, a veteran Japanese space flier.

The decision means that SpaceX will now be rotating crews for NASA at ISS every six months. It will also be reusing both the first stages and the capsules. Endeavour, the capsule used on the demo flight earlier this year, will be reused in the spring. Resilience, the capsule scheduled for launch on November 14th, will be reused next fall.

Since SpaceX also has a commercial manned flight planned for next fall, that will probably require a third capsule. With those three capsules they will have at least for the next few years a fleet will cover all their initial needs. Don’t be surprised if however the introduce an upgraded capsule or two along the way, based on what they learn on these initial flights.

The article had one other piece of new news concerning Boeing’s Starliner capsule. The second unmanned demo flight has now officially been delayed into the first quarter of next year, rather than late this year.

Canada’s government approves Starlink service

9:41 am

Capitalism in space: Canada’s government yesterday announced that it has given final approval to SpaceX’s Starlink internet service to offer those services in that country.

More here.

This final approval came from the Innovation, Science and Economic Development Canada (ISED) agency, which appears designed to protect Canadian businesses from foreign competition. It had appeared initially that they had been stalling giving their approval (maybe for political reasons). The delay however could simply have been the slowness of operation which is typical of such government bureaucracies. As noted at the first link above, however “Clearly, the government heard the demand from consumers to get this service approved.” And since there are no Canadian companies that can offer this service, it was absurd not to okay SpaceX’s operation.

This approval means that Starlink is now posed to begin commercial operations, actually selling its internet service to the public, and doing it ahead of its primary competitor, OneWeb. Considering that OneWeb had started development and satellite launching first, this achievement illustrates again SpaceX’s nimble and fast approach to business. The company does not waste time in anything it does. It might not meet all of its scheduling goals, but not for want of trying.

SpaceX has already been offering the service in its test market in the northern U.S. for the price of $99 per month plus an initial fee of $499 for equipment, with the initial user reports very positive.
