Musk: Biden delayed the return of Starliner’s astronauts “for political reasons”

During a television interview with President Trump, Elon Musk suggested that the reason the two Starliner astronauts have been forced to remain on ISS for months was because of a political decision by the Biden administration last year.

The billionaire SpaceX CEO said his company was “accelerating the return of the astronauts” as per Trump’s instructions. Musk then appeared to take a shot at the Biden administration, saying the move was “postponed kind of to a ridiculous degree,” before the president chimed in saying “they got left in space.”

When Hannity pointed out the astronauts have been on the ISS for almost 300 days instead of the planned 8 days, Trump simply said “Biden,” before Musk claimed they were “left up there for political reasons, which is not good.”

While the decision to return Starliner unmanned certainly had a political component (a desire to avoid a disaster in the final year of Biden’s term), Musk’s claim is greatly exaggerated. Worse, Musk is papering over his own company’s contribution to the delays. Had SpaceX and NASA chosen in December to use an already existing Dragon capsule instead of a brand new capsule to launch the next crew to ISS, the astronauts would be home already. Instead, they decided to get that new capsule ready, requiring an almost two month delay in their return.

When it became obvious last month that even this extra time was insufficient to get the new capsule ready, only then did SpaceX and NASA choose to switch capsules. That switch allowed them to move up the return date by about a week.

In reporting Musk’s words here, our ignorant press has generally left these details out, allowing both Musk and Trump to make it appear as they are saviors for these poor astronauts. This is simply not true. SpaceX is certainly making it possible to bring them home (something Boeing was unable to do), but it also contributed to the delay in doing so.

Cargo Dragon docked to ISS boosts station

For the first time a cargo Dragon capsule used its Draco attitude thrusters to test their ability to adjust or raise ISS’s orbit.

NASA and SpaceX monitored operations as the company’s Dragon spacecraft performed its first demonstration of reboost capabilities for the International Space Station at 12:50 p.m. EST on Friday. The spacecraft’s Draco thrusters adjusted the station’s orbit through a reboost of altitude by 7/100 of a mile at apogee and 7/10 of a mile at perigee, lasting approximately 12 minutes and 30 seconds.

This posting is late because of my Grand Canyon trip, but I’m posting this now to make sure it is on the webpage. The goal of the test was to prove another American method for adjusting ISS’s orbit, in order to replace the Russian Progress capsules which now do the job. This test proved Dragon’s thrusters can be used for small orbital adjustments, but whether it can do major orbital corrections remains unclear. A previous test using Cygnus had already showed it could do the job.

Resilience splashes down safely, ending Polaris Dawn commercial manned orbital mission

SpaceX’s Resilience capsule has just splashed down safely in the Gulf of Mexico, ending the five-day Polaris Dawn private manned orbital mission, commanded by billionaire and jet pilot Jared Isaacman.

As of posting the capsule is still in the water with divers and boats on the way.

This completes the first mission in Isaacman’s planned three mission Polaris program. It was a complete success, doing a great deal of medical research on the effects of high orbit radiation on the human body as well as the first private spacewalk using SpaceX’s first EVA spacesuits. For Isaacman’s next mission he has already proposed doing a Hubble repair mission. NASA has had mixed feelings about this idea, but after this success it will be interesting if that attitude changes.

I must comment that the coverage by SpaceX employees on this mission was somewhat annoying. For the first time, they spent a lot of time giggling and focusing on PR and how “cool” and “incredible” and “wonderful” everything was, from amusing new decals in the capsule to the spacewalk to Sarah Gillis’ violin performance.

All of this was as great as they kept saying, which is why they didn’t need to say it, over and over and over and over and over again. It would have been better if they had done what SpaceX has generally done on previous broadcasts and missions, focused on describing the technical aspects and then staying silent otherwise. Gushing like this is more like a NASA or Blue Origin broadcast, and does not do SpaceX credit.

Sarah Gillis – Rey’s Theme

An evening pause: The music is by John Williams. The lead violinist is space-walking Sarah Gillis, playing from the Resilience capsule in orbit right now.

Two astronauts on commercial Polaris Dawn manned mission complete spacewalk

Jared Isaacman during his spacewalk
Jared Isaacman during his spacewalk

Jared Isaacman and Sarah Gillis this morning each successfully completed short spacewalks outside their Resilience capsule, exiting about halfway into space but floating free except for a umbilical tether.

It was very evident that the goal of both EVAs was to check out the engineering upgrades created by SpaceX to make this spacewalk possible. Both astronauts worked very carefully to vent the capsule’s atmosphere, open the hatch, exit, then close the hatch, though Isaacman (who exited first) opened the hatch and Gillis closed the hatch. All in all it took a little less then two hours to complete both spacewalks, with Isaacman outside for about ten minutes, and Gillis for a little less.

Though the actual EVAs were relatively unambitious, they were very comparable to the first government spacewalks by America’s Ed White and Russia’s Alexei Leonov in the 1960s. The engineering data that SpaceX obtained from this spacewalk will allow it to refine its spacesuits, its capsule, and make later commercial spacewalks more complex.

This new SpaceX capability is now something the company can market to other future customers. It not only gives this American private enterprise another skill, it makes SpaceX’s commercial capabilities more valuable.

Jared Isaacman’s private spacewalk manned mission launches on Falcon 9

Early this morning SpaceX successfully launched its Resilience Dragon capsule carrying four passengers on Jared Isaacman’s mission to do the first entirely private spacewalk. The Falcon 9 rocket lifted off from the Kennedy Space Center in Florida.

Resilience is flying its third flight. The first stage completed its fourth flight, landing on a drone ship in the Atlantic.

The spacewalk will take place on September 12, 2024. In between the crew will spend the next two days preparing for that, while flying in an orbit with a apogee of 870 miles, the highest any person has flown from Earth since Apollo. That orbit will be lowered slightly for the spacewalk itself.

The leaders in the 2024 launch race:

89 SpaceX
38 China
10 Rocket Lab
9 Russia

American private enterprise now leads the rest of the world combined in successful launches 104 to 57, while SpaceX by itself leads the entire world, including American companies, 89 to 72.

NASA names revised crew for next manned Dragon mission to ISS

NASA today named the two astronauts who will fly on the next manned Dragon mission to ISS, to be launched on September 24, 2024 for a six month mission, where they will be joined by the two astronauts who launched on Boeing’s Starliner in June but now will return with them when their Freedom capsule returns in February 2025.

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov will launch no earlier than Tuesday, Sept. 24, on the agency’s SpaceX Crew-9 mission to the International Space Station. NASA astronauts Zena Cardman and Stephanie Wilson, previously announced as crewmates, are eligible for reassignment on a future mission. Hague and Gorbunov will fly to the space station as commander and mission specialist, respectively, as part of a two-crew member flight aboard a SpaceX Dragon.

The updated crew complement follows NASA’s decision to return the agency’s Boeing Crew Flight Test uncrewed and launch Crew-9 with two unoccupied seats. NASA astronauts Butch Wilmore and Suni Williams, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025.

With Starliner now scheduled to return on September 6th and Freedom not arriving until around September 24th, there will be an eighteen day period when Wilmore and Williams will have a limited and more risky lifeboat option on ISS. If an incident should occur that requires station evacuation there is room to squeeze them inside SpaceX’s Endeavour Dragon capsule presently docked there, but they will return without flight suits. Their Dragon flight suits will not arrive until September 24th, on the next Dragon. The suits they used on Starliner will not work on Dragon.

To guarantee no capsule debris hits inhabited areas, SpaceX to move its manned splashdowns to Pacific

As part of the changes SpaceX is instituting to the de-orbit procedures of its Dragon capsules in order to end any chance parts of the service module will fall in inhabited areas (as has happened several times in the past few years) the company will be shifting all manned splashdowns to the Pacific Ocean.

Repeated issues with large chunks of debris from Dragon — “trunks” where the fuel and electrical supplies are held — have repeatedly crashed down in areas ranging from Australia to North Carolina. One measure to fix that will be tasking future spacecraft after Crew-9, perhaps as soon as Crew-10, to splash down on the U.S. Pacific coast, SpaceX said during a press conference today (July 26).

“What we’ll do is we’ll implement a software change to complete the deorbit burn before jettisoning the trunk, like we did with Dragon-1, and then the trunk will intentionally land […] in an unpopulated area of the ocean,” Sarah Walker, SpaceX’s director of Dragon mission management, said in the livestreamed briefing. “So to make this change possible, we’ll move a Dragon recovery vessel to the Pacific sometime next year.”

Crew-9 is now scheduled to launch to ISS on August 18th on a six month mission, landing sometime in February 2025. Crew-10 would launch about that time and land sometime in August, 2025.

Side note: The announcement yesterday of August 18th for the launch of the next Dragon manned mission suggests NASA is now confident it can determine a date prior to that for returning Starliner. This reinforces the fact that the astronauts and Starliner are not “stranded” on the station, and any news source that states or even implies such a thing indicates it is a place where you are likely getting junk news, on all its stories.

Isaacman’s Polaris Dawn mission to launch July 31, 2024

Jared Isaacman
Jared Isaacman

According to a short notice on the Polaris Dawn webpage, Jared Isaacman’s manned orbital mission where he will do the first spacewalk by a private citizen is now targeting a launch date of July 31, 2024.

The four-person mission is planned to spend five days in orbit in SpaceX’s Resilience Dragon capsule, during which it will fly to as high as 870 miles, the highest orbit flown since Gemini 11 in 1966, and the farthest any human has flown from Earth since the Apollo lunar missions. That orbit will make possible some new radiation research:

[T]his is high enough to penetrate the inner band of the radioactive Van Allen Belts that encircle the Earth. This isn’t good for the crew consisting of Mission Commander Jared Isaacman, Mission Pilot Scott Poteet, Mission Specialist Sarah Gillis, and Mission Specialist and Medical Officer Anna Menon, but their initial orbit will be highly elliptical with a lower altitude of 120 miles (190 km), so their exposure will be minimal.

The purpose of this radiological game of chicken is to conduct 38 science experiments to study the effects of spaceflight and space radiation on human health. When these are completed, the altitude for the remainder of the five days in orbit will be reduced to 430 miles (700 km).

Isaacman will then attempt his spacewalk, opening a hatch on Resilience that replaced its docking port. While Isaacman will be the only one to exit the capsule, all four crew members will be in comparable spacesuits, since the capsule has no airlock and thus its entire atmosphere will escape during these activities.

If this mission is successful, I expect Isaacman will renew his push at NASA for making the goal of his next Polaris mission to replace the gyros on the Hubble Space Telescope. At the moment agency officials have expressed skepticism and seem uninterested. That might change however.

SpaceX studying changes to de-orbit procedures for Dragon service module

Because it appears the trunk section of the service module of SpaceX’s Dragon capsules actually survives re-entry, the company is now studying changes to its de-orbit procedures so that it can guarantee that trunk will not crash on land, as has happened now three times in the past two years.

The solution [a NASA official] said NASA and SpaceX are looking at involves changing deorbiting procedures. Currently, the trunk is released before the capsule performs its orbit burn. That means the trunk can remain in orbit for months before making an uncontrolled reentry.

Instead, [that NASA official] said engineers are examining doing the deorbit burn and then releasing the trunk. That would provide more control of where the trunk reenters, ensuring that any debris that survives reentry lands in unpopulated regions.

To make this new procedure work they need to recalculate the fuel requirements for doing the de-orbit burn. It also requires them to figure out when to detach the trunk after the burn. I expect SpaceX to successfully implement these changes before the next Dragon launch, whether manned or unmanned.

SpaceX retrieves its Dragon debris that fell in Canada in February

SpaceX yesterday sent a crew and a U-Haul truck to five different farms in Saskatchewan, Canada, to retrieve eight pieces of debris that came from the service module trunk of a Dragon cargo capsule when the trunk was de-orbited to burn up in the atmosphere in February.

I am certain SpaceX engineers want to find out why this debris survived its fall through the atmosphere, so as to better predict what will happen on future de-orbits. If they determine that more of Dragon’s service module survives re-entry than previously predicted, it will require a rethinking on where such de-orbits are planned, making sure they always occur over the ocean.

It also appears that an academic who doesn’t know much about space engineering showed up during this retrieval to talk to the press and attack SpaceX.

Samantha Lawler, a University of Regina astronomy professor, was at the farm when SpaceX employees arrived on Tuesday. She said SpaceX needs to be transparent about how its operations are affecting the atmosphere, and how incidents like this are dealt with.

Lawler was quoted more fully (and more embarrassingly) in this other news report:

“SpaceX has over 6,000 Starlink satellites in orbit that they claim will burn up completely when they re-enter. That comes to 23 re-entries per-day when they are at full capacity. If those re-entries are all making it to the ground, dropping hundred pound pieces of garbage, that will kill lots of people,” Lawler explained.

To claim that any Starlink satellites are threat to hit the ground proves Lawler knowns nothing about space engineering and is acting merely as a anti-SpaceX “Karen” who wants to harass the company. Starlink satellites are too small to pose a threat. Moreover, SpaceX from day one has acted responsibly to de-orbit them under a controlled manner.

Nonetheless, this incident in Canada suggests that more material from larger orbiting objects can reach the ground, and requires a rethinking as to where to de-orbit them.

Piece from SpaceX Dragon service module falls on Canadian farm

Though not yet confirmed a 90-pound piece of burned debris that crashed on a Canadian farm and found in late April appears to be a section from the trunk section of a SpaceX Dragon service module.

Jonathan McDowell, who tracks space launches and re-entries, posted on X (formerly Twitter) that the trunk from the private Axiom Space Ax-3 mission fell over Saskatchewan on Feb. 26.

This incident, along with several others over the last few years, tells us that not everything engineers thought would burn up upon re-entry does so. A major rethinking of how objects are de-orbited could be necessary.

ISS crew splashes down safely

SpaceX’s Endurance manned capsule yesterday safely splashed down in the Gulf of Mexico, bringing home a crew of four astronauts from ISS after completing a six month mission.

NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov, returned to Earth splashing down at 5:47 a.m. EDT. Teams aboard SpaceX recovery vessels retrieved the spacecraft and its crew. After returning to shore, the crew will fly to NASA’s Johnson Space Center in Houston.

…Moghbeli, Mogensen, Furukawa, and Borisov traveled 84,434,094 miles during their mission, spent 197 days aboard the space station, and completed 3,184 orbits around Earth. The Crew-7 mission was the first spaceflight for Moghbeli and Borisov. Mogensen has logged 209 days in space over his two flights, and Furukawa has logged 366 days in space over his two flights.

This was the third flight of Endurance. As always, it is important to note that though the passengers were government employees from the U.S., Europe, Japan, and Russia, the entire splashdown crew and capsule were private employees of SpaceX. This was a private mission, purchased by those governments.

Update on Jared Isaacman’s upcoming Polaris Dawn manned mission

Link here. Bottom line is that they still hope to launch on a five day orbital mission in SpaceX’s Resilience Dragon capsule later this year, during which they will do the first privately funded non-government spacewalk.

Developing new spacworthy spacesuits remains the biggest task before the mission can fly.

In a series of social media updates on Friday and Saturday, Isaacman answered some questions from the public about the progression of the suit development and the mission overall. He stated that over the past week, they “spent a lot of time pressurized in the EVA suits working contingencies.”

Isaacman clarified as well that, unlike missions to the International Space Station chartered by either NASA or Axiom Space, the crew members of the Polaris Dawn mission won’t launch and land while wearing IVA suits. He said because they are limited with space on this flight, they will only have their EVA suits.

No launch date has yet been set.

Russia and NASA agree to extend ISS astronaut exchanges on each other’s spacecraft through 2025

Russia and NASA have agreed to extend their barter deal through 2025, whereby each nation sends astronauts to ISS periodically on the other nation’s rockets and capsules.

This is a barter deal, with no exchange of money. The fundamental idea is to make sure astronauts on board ISS understand how the capsules from each nation operate in case of emergency. Russia had initially resisted signing such a deal after SpaceX began providing NASA its Dragon capsules and Falcon 9 rocket to get astronauts to ISS. It said this was because it did not trust SpaceX’s technology, but I suspect Roscosmos was also hoping to squeeze some cash from NASA as it was no longer being paid to fly U.S. astronauts on its Soyuz rocket and capsule. That attempt was futile. For numerous political reasons there was no way NASA was going to pay Russia anything in this barter deal.

Russia then signed on, and will keep extending this agreement until the day ISS is retired, or it finally launches its own station (something that is becoming increasingly unlikely).

The Polaris Dawn private space mission now targeting an April ’24 launch

The Polaris Dawn private space mission, the first of a three-mission private manned program being financed by billionaire Jared Isaacman, is now targeting an April 2024 launch.

In social media posts Dec. 9, Jared Isaacman, the billionaire backing the Polaris program and who is commanding the initial mission, said the launch of Polaris Dawn is now scheduled for April 2024. “April is the goal to launch & the pace of training is accelerating,” he wrote, stating that he was at SpaceX that day for testing of extravehicular activity (EVA) spacesuits that will be used on the mission.

Conducting a spacewalk is one of the major goals of Polaris Dawn, requiring both development of an EVA suit as well as modifications to the Crew Dragon, which lacks an airlock. Both of those have been challenges, he suggested in a subsequent post. There is a “big difference,” he wrote, between the pressure suits worn by Crew Dragon astronauts and an EVA suit “engineered from the start to be exposed to vacuum outside the spaceship.” The lack of an airlock also requires changes to Crew Dragon software and hardware to enable depressurization of the cabin before the start of the spacewalk and repressurization afterwards.

The mission’s launch has been delayed several times from its first launch target in 2022. This first flight of Isaacman’s Polaris program will, as noted, attempt the first spacewalk by a private citizen. The second would also fly on a Dragon capsule, but its mission remains unclear. Both NASA and Isaacman’s Polaris team have been studying the possibility of a repair mission to Hubble. The third mission would be on Starship, once it begins flying operationally.

Isaacman previously paid for and flew on SpaceX’s first commercial manned flight, Inspiration4, in September 2021.

SpaceX successfully launches a cargo Dragon to ISS

Using a Falcon 9 rocket lifting off from Cape Canaveral, SpaceX tonight successfully launched a cargo Dragon carrying supplies to ISS.

This Dragon capsule is making its second flight. The first stage also completed its second flight, landing back at Cape Canaveral. The capsule itself will dock with ISS early Saturday morning.

The leaders in the 2023 launch race:

81 SpaceX
51 China
14 Russia
7 Rocket Lab
7 India

American private enterprise now leads China 93 to 51 in successful launches, and the entire world combined 93 to 80. SpaceX by itself is once again leading the rest of the world (excluding American companies) 81 to 80.

Axiom signs deal with the United Kingdom to fly all British mission

The space agency of the United Kingdom today announced that it has signed a deal with Axiom to fly an manned mission in space, with four astronauts spending up to two weeks in space (likely in a SpaceX Dragon capsule).

The flight, estimated to cost around £200 million, is being organized in cooperation with the European Space Agency (ESA), though all the astronauts will be British. The announced commander, Tim Peake, spent six months on ISS in 2015, and has come out of retirement to do the flight.

It is also unclear at this moment whether it will fly to ISS, or simply remain in orbit. In fact, few specific details have yet been released.

The bottom line however is that the new American space industry is going to make money from Britain’s desire to be a space power. Seems like a good deal to me.

SpaceX launches four astronauts to ISS

Using its Falcon 9 rocket lifting off from Cape Canaveral, SpaceX early this morning put four astronauts into orbit for a six month mission to ISS.

The Dragon capsule, Endurance, was making its third flight. The first stage, flying for the first time, landed successfully back at Cape Canaveral.

The leaders in the 2023 launch race:

58 SpaceX
37 China
12 Russia
7 Rocket Lab

In the national rankings, American private enterprise now leads China in successful launches 67 to 37. It also leads the entire world combined, 67 to 60, while SpaceX by itself now trails the rest of the world (excluding American companies) 58 to 60 in successful launches.

A Dragon cargo capsule had a valve issue at ISS in June

The Dragon cargo capsule that had been docked to ISS in June apparently had a faulty valve that impacted no operations but has required SpaceX to review similar valves on all manned and cargo Dragon capsules.

The valve — known as an isolation valve — is designed to come on in case of a thruster leak, Reed said during the press conference. Since no leak was happening at the time it was stuck open, the valve “didn’t have to serve any purpose.”

The affected spacecraft, known as CRS-28, otherwise returned to Earth normally on June 30 after 25 days in space. After checking into the valve on CRS-28, SpaceX looked at its entire spacecraft line. They found “corrosion among certain units,” Reed said, which SpaceX is looking into identifying and addressing.

Knowing SpaceX, it will now not only find out the root cause, but fix it so that the corrosion never appears again, thus making its Dragon spacecraft even more reliable.

SpaceX successfully launches cargo Dragon to ISS

Capitalism in space: SpaceX this morning successfully launched another cargo Dragon freighter to ISS, lifting off on a Falcon 9 rocket from Cape Canaveral.

This cargo capsule is on its fourth flight. The first stage completed its fifth flight, landing on a drone ship in the Atlantic. The capsule carries about 7, 000 pounds of supplies, including another set of new solar arrays for ISS, and will dock with ISS tomorrow.

The leaders in the 2023 launch race:

38 SpaceX
20 China
8 Russia
5 Rocket Lab

American private enterprise now leads China 43 to 20 in the national rankings, and the entire world combined 43 to 36. SpaceX by itself leads the world 38 to 36, but when you add other American companies it still trails everyone else combined 38 to 42.

AX-2 commercial passenger flight to ISS splashes down safely

Axiom’s second commercial passenger flight to ISS, dubbed AX-2, successfully splashed down in the Gulf of Mexico a little after 11 pm (Eastern) tonight after spending eight days in space.

Recovery efforts of the Freedom capsule are still underway by SpaceX crews. It is necessary again to emphasize that this is a private mission, launched by a private company in a privately owned capsule for a private company and private passengers. The only government involvement was when the capsule was docked to ISS and the crew was on the station.

SpaceX launches Axiom’s second commercial manned mission to ISS

SpaceX today successfully used its Falcon 9 rocket to launch its Freedom manned capsule on its second flight, carrying four passengers on Axiom’s second commercial manned mission to ISS.

The Axiom crew included three paying passengers, one from the U.S. and two from Saudi Arabia, with the fourth crew member former NASA astronaut Peggy Whitson, now acting as Axiom’s commander. They plan to spend eight days docked to ISS. Making this commercial flight even more interesting is that the station already has a Middle Eastern commercial astronaut, from the United Arab Emirates. The Arab space race is clearing heating up.

The first stage was making its first flight, and successfully landed back at Cape Canaveral.

Were you aware this was happening? With my readers I expect so, but I am willing to bet that we are a very small minority. SpaceX has now made American manned spaceflight so routine almost no one pays attention.

The leaders in the 2023 launch race:

34 SpaceX
18 China
6 Russia
4 Rocket Lab

American private enterprise now leads China 38 to 18 in the national rankings, and the entire world combined 38 to 30. SpaceX by itself is now tied in total launches with the rest of the world, including American companies.

NASA agrees to Axiom’s third planned commercial passenger mission to ISS

NASA today announced that it has given Axiom the go-ahead for its third planned commercial passenger mission to ISS, now tentatively scheduled for November 2023.

Axiom Mission 3 (Ax-3) is expected to spend 14 days docked to the space station. A specific launch date is dependent on spacecraft traffic to the space station and in-orbit activity planning and constraints. NASA and Axiom Space mission planners will coordinate in-orbit activities for the private astronauts to conduct in coordination with space station crew members and flight controllers on the ground.

As NASA did in announcing its agreement to Axiom’s previous flight, the agency’s press release makes believe it “selected” Axiom for this flight, as if it had the power and right to do so. Hogwash. Axiom has purchased the flight from SpaceX, and wishes to rent space on ISS for two weeks for its customers. All NASA has done is agree to the deal, while also charging Axiom very large fees for that rental.

SpaceX launches cargo Dragon to ISS

Capitalism in space: SpaceX tonight successfully used its Falcon 9 rocket to put a cargo Dragon capsule into orbit and on its way to ISS.

The first stage successfully completed its seventh flight, landing on a drone ship in the Atlantic. The Dragon freighter is making its third flight, and will dock with ISS on the morning of March 16th.

The 2023 launch race:

17 SpaceX
9 China
4 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise now leads China 18 to 9 in the national rankings, and the entire world combined 18 to 15. SpaceX alone leads entire world, including the rest of the U.S., 17 to 16.

Endeavour docks with ISS

Endeavour tonight has successfully docked with ISS.

When the spacecraft got within about 70 feet of the station, there was a delay of a little more than an hour while ground controllers installed a software overide to a sensor for monitoring the position of one of the 12 hooks on Endeavour, used to lock it to ISS’s docking port. Though visual and other data showed the hook was working, the sensor could not, and without that software override Endeavour would automatically abort the docking.

This same sensor had caused a delay in the opening of the capsule’s nosecone yesterday shortly after launch.

As of posting the hatch had not yet been opened, something that should occur in about an hour or so. Though Endeavour is docked, more checks needed to be done beforehand.

SpaceX successfully launches its Endeavour capsule carrying four astronauts

Capitalism in space: SpaceX tonight used its Falcon 9 rocket to successfully launch its Endeavour capsule from Cape Canaveral, carrying four astronauts to ISS.

This was Endeavour’s fourth flight. It will dock with ISS in about 24 hours. The four-person crew included two Americans, one Russian (the second to fly on a Dragon capsule), and the first citizen of the United Arab Emirates to fly on an American spacecraft. He will stay on the station for six months.

The Falcon 9 first stage was making its first flight, and successfully landed on a drone ship in the Atlantic. This was only the fourth new first stage used by SpaceX since January 2022 (out of 75 launches), and the second launched this year.

The 2023 launch race:

14 SpaceX
7 China
3 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise now leads China 15 to 7 in the national rankings, and the entire world combined 15 to 12. SpaceX alone leads the entire world combined, including all other American companies, 14 to 13.

Manned Endeavour launch tonight on Falcon 9 scrubbed at T-2:12

UPDATE: New launch date, still tentative pending investigation into the technical issue that forced tonight’s scrub, is now March 2, 2023, at 12:32 am Eastern.

The fourth manned launch of SpaceX’s Endeavour Dragon capsule, carrying four astronauts, was scrubbed tonight at T-2:12 because of an issue with ground ignition system of the rocket. As of posting no additional details had been released, as the launch team was in the process of standing down, unloading the fuel from the rocket in preparation for getting the astronauts out of the capsule safely.

Assuming the issue can be fixed quickly, there is another launch opportunity tomorrow, February 28, at 1:22 am (Eastern). For SpaceX a launch scrub for technical reasons has become remarkably rare. In fact, the only other scrub since 2020 for technical reasons took place in July 2022. During that time the company successfully launched more than 100 times, thus getting off the ground as scheduled about 99% of the time, excluding weather delays.

While the Endeavour capsule will be making its fourth flight, when this launch finally takes place the rocket’s first stage is a new stage and will be making its first flight. This has also become a relatively rare event for SpaceX. In 2022, of the company’s 61 launches, only three used new first stages. So far this year this launch will be the second new stage to fly, out of the thirteen launches so far.
