Funding breakdown for three lunar landing contracts

3:47 pm

Capitalism in space: The contracts awarded by NASA yesterday to build manned lunar landers totaled almost a billion dollars, distributed as follows:

  • Blue Origin: $579 million
  • Dynetics: $253 million
  • SpaceX: $135 million

That Blue Origin got the biggest amount might have to do with the bid’s subcontractors, Lockheed Martin and Northrop Grumman. This gives these traditional big space partners, who normally rely on these kinds of government contracts and have little ability to make money outside them, some financing. This will also please their political backers in Congress.

For SpaceX, this is the first time they have taken any government money in connection with Starship. It also appears that NASA is going to stay back and generally let SpaceX develop it without undue interference.

Starlink satellites, not aliens, are those strings of lights in the night sky

1:12 pm

Apparently many people have been seeing the reflected strings of SpaceX’s new Starlink satellites in the night sky, and are calling news organizations asking about them.

Some viewers have noticed the “lights” in the sky will go dark, one by one. This is due to the reflection of light from the moon and Earth and how the position of the satellites change.

Elon Musk, the founder and CEO of SpaceX, detailed a plan this week to “mitigate the impact of their Starlink satellite constellation on night sky observation,” according to an article on Tech Crunch.

In that Tech Crunch article, Musk describes how they are installing sun visors on the satellites to prevent the reflections and make them hopefully invisible to the Earthbound observers.

This will make the astronomy crowd happy, which wants its new big ground-based telescopes to be useful. I think they should instead be focusing their effort in building more space-based telescopes.

NASA contract award for manned lunar landers rejects SLS

12:12 pm

Capitalism in space: NASA today announced the award of contracts to three different private companies to develop manned lunar landers for the 2024 Artemis Moon mission, all of which will not use the SLS rocket to get to the Moon.

The press release described the awards as follows:

  • Blue Origin of Kent, Washington, is developing the Integrated Lander Vehicle (ILV) – a three-stage lander to be launched on its own New Glenn Rocket System and ULA Vulcan launch system.
  • Dynetics (a Leidos company) of Huntsville, Alabama, is developing the Dynetics Human Landing System (DHLS) – a single structure providing the ascent and descent capabilities that will launch on the ULA Vulcan launch system.
  • SpaceX of Hawthorne, California, is developing the Starship – a fully integrated lander that will use the SpaceX Super Heavy rocket.

All, including NASA and the Trump administration, are aiming to get these landers built and launched by the Trump administration’s 2024 deadline.

The first thing that stands out like a beacon is the exclusion of SLS as the rocket to launch any of these landers. Instead, the aim is to use the cheaper privately built rockets of either SpaceX, ULA, or Blue Origin.

The second thing that stands out is the commitment by SpaceX to use its Super Heavy/Starship rocket, not its Falcon Heavy. This means they are directly telling the world that they expect this rocket to be in operation much sooner than most expect. It also suggests that they hope this rocket will supplant SLS as the main rocket to get to the Moon. The award also means that NASA is agreeable to this.

The third thing that stands out is the exclusion of Boeing, which submitted a bid but did not win. Not only does this exclusion reinforce the sense gotten from an earlier report that NASA was very dissatisfied with Boeing and was thus going to rank it very low in future bidding considerations, it also indicates once again that NASA is seriously looking at other options to SLS. Boeing’s rejected bid was apparently the only one linked to SLS, and was rejected.

In fact, that SLS was not mentioned as the rocket for any of these landers strongly indicates that NASA and the Trump administration is finally abandoning SLS as the rocket to get Americans to the Moon.

Which immediately raises the question: Why the hell are we spending any money building it? It no longer has any purpose at all.

4th Starship prototype passes tank pressure test

8:41 am

Capitlism in space: SpaceX’s fourth Starship prototype has successfully passed a tank pressure test, the first to do so, allowing engine testing to now begin.

In the end, SN4 passed the cryogenic proof test – hitting 4.9 bar. SpaceX CEO Elon Musk admitted in a tweet that this was “kind of a soft ball…” However, “that’s enough to fly,” he added. It is now expected to move on to engine testing within the coming days.

Currently, SpaceX has three flight-ready Raptor engines waiting for the opportunity to participate in the testing. One of these engines will be installed on SN4. A Raptor engine is not installed until after the cryogenic proof test, as that test uses hydraulic pistons to simulate the forces created by Raptors during flight.

After SpaceX performs the Raptor installation on SN4, teams will need to conduct checkouts of the engine on the vehicle. These will include gimbal, ignitor, and fuel pre-burner tests, among others. Only then will SpaceX be ready to attempt a static fire. April 29 was originally the target for a static fire test, but a one day delay with the cryogenic proof test means that the static fire is now likely targeting no earlier than April 30

All in all, the company’s target of doing a hop with this prototype this summer appears increasingly likely.

NASA’s safety panel rubberstamps May 27 manned Dragon launch

11:03 am

NASA’s safety panel has apparently reluctantly given its “okay” for the launch of the first manned Dragon launch on May 27th.

NASA’s Aerospace Safety Advisory Panel (ASAP), meeting by teleconference April 23, said it was unable to talk with NASA’s commercial crew program during its quarterly meeting, which was held virtually because of the coronavirus pandemic. The panel’s chair, Patricia Sanders, said that scheduling issues prevented a meeting, but that her committee planned to hold a “part 2” of their quarterly meeting in early May to discuss commercial crew and other topics not taken up this week.

Sanders said the panel has been kept up to date by NASA about commercial crew activities, including plans for SpaceX’s Demo-2 crewed test flight scheduled for May 27. “We are aware of a few technical items that remain to be more fully understood,” she said, “but the path forward appears feasible.”

In other words, it appears that NASA’s management might have taken advantage of the Wuhan panic to cut the panel off from the decision-making process, possibly because this panel has acted now for years to slow progress and in fact discourage any American manned launches at all, out of an almost irrational fear of any failure.

Their recommendations have sometimes verged on the ludicrous, such as an insistence that no manned launch be scheduled until a lot of paperwork was filled out.

It could also be that the panel has recognized at last (or maybe NASA management told them in no uncertain words) that we now have to proceed with American manned missions, since with the expiration of our contract with the Russians we have no other options.

SpaceX rolls out next Starship prototype

9:59 am

Capitalism in space: SpaceX has completed construction of its next Starship prototype and has moved it to its test stand in preparation for further tests.

This is the fourth prototype. If the tank pressure tests go well, they hope to add engines and do a twelve mile hop with this prototype, landing vertically. If not, they will try again with later prototypes. Regardless, the goal is to do that hop this year.

Swarm and Momentus team up to launch and position satellites

9:37 am

Capitalism in space: Swarm, builder of the tiny cubesats dubbed SpaceBees, has teamed up with Momentus to use that company’s Vigoride cubesat upper stage to position its satellites in different orbits after launch.

Under an agreement announced April 22, Momentus will arrange rides for 12 Swarm SpaceBee satellites on a SpaceX Falcon 9 rideshare mission in December 2020 with additional SpaceBee launches scheduled in 2021 and 2022.

To offer global coverage for customers seeking to relay messages through the internet, Swarm satellites must be stationed in different orbital planes and spread out within those orbital planes like a string of pearls, Sara Spangelo, Swarm co-founder and CEO, told SpaceNews.

For the Falcon 9 launch in December, Momentus will not move Swarm SpaceBees to a new orbital plane. In the future, Momentus’ Vigoride in-space shuttle will offer Swarm the option of moving SpaceBees from the rocket’s drop-off point to different locations, Negar Feher, Momentus vice president of product and business development, said by email.

Both companies have raised significant investment capital.

SpaceX successfully launches 60 more Starlink satellites

1:28 pm

Capitalism in space: SpaceX today successfully launched 60 more Starlink satellites.

The launch was significant in several ways. They reused the first stage for the fourth time, landing it successfully. They reused the fairing for the second time.

And with this launch, the Falcon 9 has now flown more than the Atlas 5, and has the most launches of any active American rocket.

This flight marks a major point in U.S. launch operations, as Falcon 9 reaches 84 flights to its name and officially takes the mantle from Atlas V as the most flown, currently operational U.S. rocket.

Atlas V began flying on 21 August 2002 and has 83 flights to its name after 18 years — for an annual rate of 4.6 launches. Falcon 9 began flying on 4 June 2010 and will reach 84 flights in just under 10 years with a flight rate of 8.4 launches per year.

That SpaceX overtook the Atlas 5 so quickly indicates exactly how successful SpaceX has been in grabbing market share from all its launch competitors.

I have embedded the video of the launch below the fold.

The leaders in the 2020 launch race:

6 China
6 SpaceX
5 Russia

The U.S. now leads China 10 to 6 in the national rankings.

Rock droplets hitting a Martian plain

12:42 pm

Depressions in Amazonis Planitia
Click for full image.

Cool image time! The photo the right, rotated, cropped, and reduced to post here, is not only cool, it contains a punchline. It was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on February 11, 2020 and shows one small area between two regions in the northern lowlands of Mars, dubbed Amazonia Planitia (to the south) and Arcadia Planitia (to the north) respectively.

This region is thought to have a lot of water ice just below the surface., so much in fact that Donna Viola of the University of Arizona has said, “I think you could dig anywhere to get your water ice.”

I think this image illustrates this fact nicely. Assuming the numerous depressions seen here were caused by impacts, either primary or secondary, it appears that when they hit the ground the heat of that impact was able to immediately melt a wide circular area. My guess is that an underwater ice table immediately turned to gas so that the dusty material mantling the surface then sagged, creating these wider circular depressions.

Of course, this is merely an off-the-cuff theory, and not to be taken too seriously. Other processes having nothing to do with impacts could explain what we see. For example, vents at the center of these craters might have allowed the underground ice to sublimate away, thus allowing the surface to sag.

So what’s the punchline?

Russians slash their launch prices by 39%

9:08 am

Capitalism in space: Having lost their entire commercial market share because of SpaceX’s lower prices, the Russians have finally decided to slash their launch prices by 39%.

As the article notes, the cost for a Proton rocket launch was once $100 million. Then SpaceX came along with a $60 million pricetag. At first the Russians poo-pooed this, and did nothing. When their customers started to vanish however they decided to finally compete, so a year ago they cut the Proton price to match SpaceX’s.

Because of SpaceX’s ability to reuse its first stages, however, that $60 million price no longer worked. SpaceX had a year earlier lowered its prices even more, to $50 million, for launches with used first stages.

This new price slash by Roscosmos probably brings their price down to about $36 million, and thus beats SpaceX.

We shall see whether it will attract new customers. It definitely is now cheaper, but it is also less reliable. Russia continues to have serious quality control problems at its manufacturing level.

That SpaceX’s arrival forced a drop in the price of a launch from $100 million to less than $40 million illustrates the beautiful value of freedom and competition. The change is even more spectacular when you consider that ULA, the dominant American launch company before SpaceX, had been charging between $200 to $400 million per launch. For decades the Russians, ULA, and Arianespace refused to compete, working instead as a cartel to keep costs high.

SpaceX has ended this corrupt practice. We now have a competitive launch industry, and the result is that the exploration of the solar system is finally becoming a real possibility.

Correction: I originally called ULA “the only American launch company before SpaceX.” This was not correct, as Orbital Sciences, now part of Northrop Grumman, was also launching satellites. It just was a very minor player, with little impact. It was also excluded from the military’s EELV program, and thus could not launch payloads for them after around 2005.

First manned Dragon flight scheduled for May 27th

10:30 am

Capitalism in space: NASA today officially announced May 27, 2020 as the scheduled launch date for the first manned Dragon flight to ISS, the first time American astronauts will fly from American soil on an American rocket in an American spacecraft since the shuttle was retired almost a decade ago.

The launch is set for 4:32 pm (Eastern), and I am sure will be live streams by both NASA and SpaceX.

SpaceX reuses sections of damaged Starship prototype for next version

9:07 am

Capitalism in space: In building its fourth Starship prototype for testing, SpaceX has decided to reuse large sections of the previous Starship prototype, badly damaged during a pressure test several weeks ago.

On April 15th, eight days after Starship SN3’s [the damaged third prototype] remaining aft section was cut in half, the rearmost half – known as the skirt – was spotted stacked beneath a brand new engine section built for SN4. While confirming that a significant part of SN3 will be reused on SN4, it also indicates that only a less critical SN3 remnant was fit to join SpaceX’s next prototype.

Though they are not reusing the engines from that third prototype, I have full confidence they will, as they were part of the same bottom section of that prototype that was damaged during the test. This statement is incorrect. I had mistakenly assumed that because SpaceX had said it planned actual test hops eventually with this third prototype that three engines were already in place. They were not.

First manned Dragon mission slips to end of May

9:12 am

Capitalism in space: According to NASA administrator Jim Bridenstine, the first manned flight of SpaceX’s Dragon capsule will now occur at the end of May, not mid-May, and will last two or three months.

“I think we’re really good shape,” Bridenstine said in an interview Thursday. “I’m fairly confident that we can launch at the end of May. If we do slip, it’ll probably be into June. It won’t be much.”

The article at the link also reveals that the two astronauts will spend between two to three months on board ISS, not two weeks as originally planned.

Boeing’s fall from grace at NASA

9:26 am

Eric Berger at Ars Technica yesterday uncovered a NASA report that outlined its selection process for awarding a contract for providing cargo to the agency’s proposed Lunar Gateway space station — eventually won by SpaceX — that gave Boeing’s proposal a terrible ranking.

Of the four contenders, [Boeing] had the lowest overall technical and mission suitability scores. In addition, Boeing’s proposal was characterized as “inaccurate” and possessing no “significant strengths.” Boeing also was cited with a “significant weakness” in its proposal for pushing back on providing its software source code.

Due to its high price and ill-suited proposal for the lunar cargo contract, NASA didn’t even consider the proposal among the final bidders. In his assessment late last year, NASA’s acting chief of human spaceflight, Ken Bowersox, wrote, “Since Boeing’s proposal was the highest priced and the lowest rated under the Mission Suitability factor, while additionally providing a conditional fixed price, I have decided to eliminate Boeing from further award consideration.” [emphasis mine]

The highlighted words could possibly be a death sentence for Boeing. The company has numerous other serious problems, including its commercial 737-Max airplane, its KC-46 Pegasus tanker for the Air Force, and of course its SLS rocket for NASA. For NASA to say that it will no longer consider Boeing in future contract bidding, especially since NASA has been one of Boeing’s biggest customers for decades, cannot be good for the company’s already badly suffering bottom line.

Berger also notes how much NASA’s attitude toward Boeing has changed since the agency removed Bill Gerstenmaier as head of its manned space operations. Gerstenmaier had apparently given Boeing the highest marks routinely, and appeared to have lost his ability to look at the company objectively. Moreover, his (and NASA’s) kid-glove treatment of Boeing for decades probably contributed to that company’s sloppy bid on the Lunar Gateway cargo contract. They were likely not used to tough questioning, and didn’t put the proper effort into writing their bid.

For the taxpayer and the American space effort, however, this report is wonderful news. It appears that NASA is breaking its tight and blind partnership with the big space contractors that has for decades handicapped the nation’s ability to get things built in space. These contractors have not been able to deliver, but because of their powerful allies on Congress, NASA has for years kowtowed to them in contract awards.

Now however it appears NASA’s management has become quite willing to reject these powerful companies, despite Congressional backing, in order to get the best deal and the best product, for the nation.

SpaceX moves forward on Starlink launch April 16

9:55 am

Capitalism in space: Despite the recent postponement by customers of two other planned launches because of the Wuhan panic, SpaceX appears to be moving ahead with plans to launch another sixty of its own Starlink satellites on April 16.

According to one unconfirmed news report, six SpaceX employees have tested positive for coronavirus. The company has not commented, however, either on this report or on its own internal policies for dealing with the Wuhan panic.

The Space Force meanwhile has not shut down its range operations in Florida, thus allowing launches from anyone to go forward.

Wuhan panic causes Space Force to delay launch

9:32 am

The Space Force yesterday announced that it is delaying the April launch by SpaceX of a GPS satellite until June, though they say in their announcement that they also still intend to get all three GPS launches off this year, as originally planned.

It seems they decided that since the in-orbit constellation is operating well, with lots of redundancy, they could afford to wait two months to launch this new upgraded GPS satellite.

Third Starship prototype collapses during tank pressure test

8:44 am

During the final part of a tank pressure test the third SpaceX Starship prototype apparently collapsed, its outer welded hull failing.

Video below the fold. The prototype is on the right, and it appears it fall inward along its hull welds.

The SN3 (Serial Number 3) vehicle incorporated lessons learned from previous vehicles and test articles, and took advantage of improved manufacturing techniques and expanded facilities at SpaceX’s South Texas launch facility.

The next round of testing began this week with cryogenic proof testing. These tests saw the vehicle filled with liquid nitrogen at cryogenic temperatures and flight pressures. Proof testing began in Thursday and continued through to Friday morning when SN3 failed during what appeared to be the end of the test.

With Elon Musk noting “we will see what data review says in the morning, but this may have been a test configuration mistake,” on Twitter and the first-look observations, the fault may have been related to detanking, rather than another failure under pressure.

I’m no engineer, so I wonder how detanking could cause such a failure.

SpaceX bans use of Zoom by employees

10:18 am

For security reasons, SpaceX has banned its employees from using Zoom for video conferencing or communications.

Elon Musk’s rocket company SpaceX has banned its employees from using video conferencing app Zoom, citing “significant privacy and security concerns,” according to a memo seen by Reuters, days after U.S. law enforcement warned users about the security of the popular app.

…The Federal Bureau of Investigation’s Boston office on Monday issued a warning about Zoom, telling users not to make meetings on the site public or share links widely after it received two reports of unidentified individuals invading school sessions, a phenomenon known as “zoombombing.”

Investigative news site The Intercept on Tuesday reported that Zoom video is not end-to-end encrypted between meeting participants, and that the company could view sessions.

It appears that Musk’s concern is that someone might use Zoom’s security weaknesses to do some industrial spying. Based on what I have read about Zoom, it seems to me that Musk’s concern is valid.

NASA selects full crew for first operational Dragon mission

10:23 am

Even though SpaceX’s first demonstration manned mission to ISS has not yet occurred, NASA yesterday announced the selection of the full four person crew for the second flight, set for later this year and intended as the first operational mission to ISS, lasting six months.

This announcement tells us several things, all good. First, it appears NASA has now definitely decided that the demo mission, presently scheduled for mid-May, will be a short-term mission. They had considered making it a six-month mission, but it now appears they have concluded doing so will delay the demo launch too much.

Second, that NASA is solidifying its plans for that operational flight, the second for Dragon, including a tentative launch date later in 2020, is further evidence that they intend to go through with the demo mission in mid-May.

Finally, it appears that NASA has decided that it will not buy more seats on Russian Soyuz capsules, something that they had previously hinted they needed to do because the agency was worried the American capsules would not be ready this year. The article describes the negotiations on-going with the Russians about the use of Dragon, as well as the future use by Americans of Soyuz. NASA wishes to have astronauts from both countries fly on both spacecraft (Starliner too, once operational), but Russia is as yet reluctant to fly its astronauts on Dragon. They want to see that spacecraft complete more missions successfully.

Regardless, future flights of Americans on Soyuz will cost NASA nothing, as the agency wishes to trade the seats on the U.S. capsules one-for-one for the seats on Soyuz. It also means that NASA has decided it doesn’t need to buy Soyuz flights anymore, as it now expects Dragon to become operational this year.

SpaceX prepares next Starship prototype; releases Starship user manual

9:58 am

From SpaceX's first user manual for Starship

Capitalism in space: Even as SpaceX has begun preparing its third Starship prototype for new testing, it has also released a first user manual for the rocket, outlining its proposed capabilities and potential uses by customers.

From the first link:

The next round of testing is anticipated to begin this week with cryogenic proof testing. These tests will see the vehicle filled with liquid nitrogen at cryogenic temperatures and flight pressures. Prior Starship test vehicles have had their campaigns cut short by failed cryogenic testing, including the last flight vehicle SpaceX rolled to the Boca Chica launch pad, Starship SN1.

If all goes right, they hope to begin short flight tests with this prototype, moving to longer and higher flights with the next.

The user manual [pdf] is mostly a short description of what they hope they will be able to accomplish with Starship. It notes that they will build both a cargo and manned variety, and that both will be available for point-to-point transportation on Earth. It also notes:

Starship has the capability to transport satellites, payloads, crew, and cargo to a variety of orbits and
Earth, Lunar, or Martian landing sites. Potential Starship customers can use this guide as a resource for preliminary payload accommodations information.This is the initial release of the Starship Users Guide and it will be updated frequently in response to customer feedback.

I guarantee that much of what is written and drawn here, such as the illustration above, will change significantly as development proceeds.

SpaceX commercial launch for Argentina postponed because of COVID-19

9:03 am

Because of travel restrictions imposed by the worldwide panic over the COVID-19 virus, Argentina’s space agency has postponed the planned March 30, 2020 launch by SpaceX of an Earth observation radar satellite.

“This decision (to postpone the launch) has been made considering the restrictions imposed by the COVID-19 pandemic and that could affect the availability of own resources and foreign third-party resources, necessary not only for a safe insertion into orbit, but also for further operation of the satellite,” CONAE said in a statement.

CONAE said the decision to postpone the launch, which was made in consultation with SpaceX, is the “best decision in these moments of uncertainty … that the whole world suffers because of COVID-19.”

Argentina has halted all flights to and from the United States, impacting the ability of Argentine personnel needed to support the planned launch to travel to the Florida spaceport.

The more I research the Wuhan flu, the more I am convinced that the world’s governments have gone crazy. More on this later today.

Dragon parachute test aborted

8:51 am

Because of the failure of the equipment unrelated to the parachutes, the helicopter pilot for a drop test of SpaceX’s crew Dragon parachutes on March 24, 2020 was forced to release the dummy capsule early, causing its loss.

“During a planned parachute drop test today, the test article suspended underneath the helicopter became unstable,” SpaceX said Tuesday in an emailed statement. “Out of an abundance of caution and to keep the helicopter crew safe, the pilot pulled the emergency release,” the statement added. “As the helicopter was not yet at target conditions, the test article was not armed, and as such, the parachute system did not initiate the parachute deployment sequence. While the test article was lost, this was not a failure of the parachute system, and most importantly, no one was injured. NASA and SpaceX are working together to determine the testing plan going forward in advance of Crew Dragon’s second demonstration mission.”

This issue, combined with the loss of a Falcon 9 first stage (on its fifth flight) during re-entry, because one engine failed to function properly, is making some news sources suggest that NASA will delay the planned May launch of Dragon’s first manned mission to ISS.

If NASA demands a delay of that May manned mission because of these two issues, it will demonstrate how truly insane our society has become. While the issue prevented the drop test, it involved the equipment that suspended the dummy capsule below the helicopter, not the parachute system. Furthermore, this test was one of the very last tests of the parachute system, following a test campaign during the past few months that has worked repeatedly on numerous tests.

As for the first stage loss, do I have to repeat again that it occurred on the stage’s fifth reuse, and after it had successfully launched its payload into orbit? SpaceX will be using a new first stage for the manned mission, and they have experienced no failures on a new first stage like this for literally years.

In a sane society, NASA would look at the overall context, and put aside these issues as irrelevant to their launch schedule. They, and SpaceX, will want to figure out what happened, but they should insist on proceeding on schedule for the May launch.

We are no longer sane however. I will not be surprised if they announce a further launch delay.

More Boca Chica residents move out, accepting SpaceX offers

More Boca Chica residents have accepted SpaceX purchase offers, and are finding other places to live.

While not all are thrilled with the circumstances, the article suggests that there is far more good will then unhappiness. It appears the excitement of what SpaceX is doing, and its willingness to give these residents special viewing privileges in the future, has done wonders to ease the pain for many of them for having to sell their homes.

It has also produced youtube channels providing 24 hour live streams of SpaceX operations.

SpaceX recovers both fairing halves from Starlink launch

10:15 am

Capitalism in space: The two reused fairing halves that SpaceX used in yesterday’s Falcon 9 Starlink launch were both successfully recovered.

Starlink V1 L5 is now the second time ever that SpaceX – or anyone, for that matter – has successfully reused an orbital-class launch vehicle payload fairing, while the mission also marked the first time that SpaceX managed to recover a reused Falcon fairing. The burn from booster issues certainly isn’t fully salved, as twin fairing catchers Ms. Tree and Ms. Chief both missed their fairing catch attempts, but both twice-flown fairing halves were still successfully scooped out of the Atlantic Ocean before they were torn apart.

The first reused fairing however was not recovered, making this recovery the first of used fairings. The company now has the ability to study them in order to better design future reusable fairings.

The article provides a lot of information about the difficulties of catching the fairings before they hit the water. It also notes that the reused fairings have all been fished out of the ocean, suggesting that in the end catching them in the ship’s nets will be unnecessary.

NASA confirms May target date for first manned Dragon flight

10:00 am

Capitalism in space: In announcing today it is beginning media accreditation for SpaceX’s first manned Dragon flight to ISS, the agency confirmed earlier reports from SpaceX that they are now aiming for a mid-to-late May launch.

Much can change before then. COVID-19 could get worse, shutting down all launches. The engine failure on yesterday’s successful Falcon 9 launch could require delays.

However, right now, things look good for May, which will be the first time since 2011 that Americans will launch from American soil on an American-built rocket, an almost ten year gap that has been downright disgraceful. Thank you Congress and presidents Bush and Obama! It was how you planned it, and is also another reason we got Trump.

SpaceX launches another sixty Starlink satellites

9:18 am

Capitalism in space: SpaceX today successfully launched another sixty Starlink satellites into orbit, using a reused first stage for the fifth time, the first time they have done this. They also for the first time reused the fairing, for the second time. All told, the cost for this launch was reduced by approximately 70% by these reuses.

However, during launch one 1st stage Merlin engine shut down prematurely, the first time since 2012. You can see the consequence of this during the re-entry burn. After the burn, the rocket seems far more unstable then normal. Soon after the video cut out, and they must have missed the drone ship upon landing, making it a failure. They intend to do a full investigation before their next launch.

The leaders in the 2020 launch race:

5 China
5 SpaceX
3 Russia
2 Arianespace (Europe)

The U.S. now leads China 8 to 5 in the national rankings.

One additional detail: At the beginning of their live stream, they touted Starship/Super Heavy, and put out a call for engineers to apply to work for SpaceX.

The launch is embedded below the fold.

Falcon 9 aborts automatically at T minus 0

10:23 am

A SpaceX launch attempt today to put sixty more Starlink satellites into orbit aborted at T minus Zero when the rocket’s computer software shut things down just after the engines began firing.

I have embedded the video below the fold. According to the broadcast, they had “a condition regarding engine power,” suggesting that one or more of the Merlin engines did not power up as expected and the computers reacted to shut the launch down because of this.

Not surprisingly, they have not yet announced a new launch date.

Manned Dragon mission targeted for May

10:18 am

Capitalism in space: According to one SpaceX official, they are now aiming for a May target date for their first manned Dragon mission to ISS, even as they will maintain a launch pace of one to two launches per month.

SpaceX president and chief operating officer Gwynne Shotwell [said] that she expects at least one to two launches per month in the near future, whether they be for customers or for SpaceX’s own internet-satellite constellation, Starlink. “And we are looking at a May timeframe to launch crew for the first time,” Shotwell continued. That launch, called Demo-2, will send NASA astronauts Bob Behnken and Doug Hurley to and from the International Space Station (ISS) aboard SpaceX’s Crew Dragon capsule.

At that pace SpaceX will complete between 12 to 24 launches for the year. They had predicted they would complete 21, so this is in line with that prediction.

The last cargo Dragon to berth with ISS using robot arm

9:31 am

Astronauts yesterday used the robot arm on ISS to berth SpaceX’s cargo Dragon freighter, the last time a Dragon capsule will be berthed to the station in this manner.

The successful supply deliver marked the 20th time a SpaceX Dragon cargo capsule has arrived at the space station since May 2012. The mission, known as CRS-20 or SpaceX-20, also the final flight of SpaceX’s first-generation Dragon spacecraft, which the company is retiring in favor of a new Dragon capsule designed to dock directly with the space station without needing to be captured by the robotic arm.

I could put this another way that is more embarrassing to NASA. After twenty flights, the agency has finally admitted that SpaceX can design a spacecraft that can do automatic dockings, and is now willing to allow it.

That of course is a gross simplification. Nonetheless, the successful unmanned demo flight last year of SpaceX’s crew Dragon, docking directly with ISS, has proven SpaceX can do it. And since that crew Dragon is essentially the same design for SpaceX’s future cargo Dragons, it makes sense to shift from robot-arm-berthing to direct docking for all future Dragon flights.

SpaceX raises $500 million for Starship, twice the amount planned

8:56 am

Capitalism in space: In a just completed fund-raising round, SpaceX raised twice the investment capital proposed, $500 million instead of $250 million.

These funds are in addition to the $1.33 billion raised previously. And according to the SpaceX official in charge of their Starlink satellite constellation, most of this money is not for Starlink:

While SpaceX expects it will cost about $10 billion or more to build the Starlink network, [vice president Jonathan] Hofeller said the company’s fundraising so far has largely not been directed to the Starlink division, as “we’ve been able to fund the development of Starlink primarily from our internal businesses.” He declared the company is in a “different position” in how it raises funds compared to other companies that are building satellite networks. “That’s why, in general, we’ve been very quiet about what we’re doing because we don’t need to go out and raise money for this particular venture,” Hofeller said.

This means the $1.83 billion raised is almost certainly all for developing Starship/Super Heavy.

Can SpaceX build this new heavy lift completely reusable rocket for that price? Considering that it cost them $500 million to develop Falcon Heavy, and that much of the engineering work from that will be applicable for the new rocket, I am willing to bet that they can.

My prediction is further reinforced by the company’s recent activities testing Starship’s tanks at Boca Chica, Texas. Only two weeks after a test to failure (resulting in some spectacular fireworks), the company has apparently successfully completed new tank tests on the next prototype.

In other words, they blew up a prototype, were able to clean up the mess, redesign what failed, and test it successfully, in only two weeks. To say such a pace would be impossible for NASA and its big space contractors like Boeing is probably the biggest understatement I’ve ever made.

This success should not make anyone think that the challenge of building Starship/Super Heavy will be easy or fast. This effort will be cutting edge engineering that in many ways will be beyond that edge. SpaceX is guaranteed to have further test failures along the way. Their pace, management approach, and track record however shows that the company knows how to deal with such issues, and will thus be able to proceed to completion.
