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.
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.

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.
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.
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.
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.
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 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.
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.
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.
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.

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.
