ULA launches the second set of Kuiper satellites into orbit

8:44 am

ULA this morning successfully placed 27 Kuiper satellites into orbit, its Atlas-5 rocket lifting off from Cape Canaveral in Florida.

This was the second set of Kuiper satellites launched for Amazon. It now has 54 satellites in orbit, with a requirement to launch about 1,600 by July of 2026.

As this was only the second launch in 2025 for ULA, both Atlas-5 launches of Kuiper satellites, the leader board in the 2025 launch race remains unchanged.

77 SpaceX
35 China
8 Rocket Lab
7 Russia

SpaceX still leads the rest of the world in successful launches, 77 to 58.

ULA had predicted it would do 20 launches in 2025. It appears the company will not only not reach that goal, it will not do so by a lot.

ULA scrubs 2nd Kuiper constellation launch due to technical issue

10:24 am

ULA today scrubbed its second Atlas-5 launch to place 27 more of Amazon’s Kuiper constellation satellites into orbit due to “an engineering observation of an elevated purge temperature within the booster engine.”

At the moment no new launch date has been scheduled.

So far Amazon has only placed 27 operational Kuiper satellites into orbit, on a single Atlas-5 launch in April. According to its FCC license, it must have 1,600 satellites in orbit by July 2026. Though it has contracts to launch these satellites 46 times on ULA rockets (8 on Atlas-5 and 36 on Vulcan), 27 times on Blue Origin’s New Glenn, 18 times on ArianeGroup’s Ariane-6, and 3 times on SpaceX’s Falcon-9, except for SpaceX all these companies have had problems getting off the ground.

Whether Amazon can meet the FAA licence requirement by next year is becoming increasingly questionable.

ULA launches Amazon’s first 27 Kuiper constellation satellites; SpaceX launches more Starlinks

4:17 pm

Two more launches today. First, SpaceX completed another Starlink launch, placing 27 satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California, with its first stage completing its 25th flight, landing on a drone ship in the Pacific.

Next, ULA successfully launched the first 27 Kuiper internet constellation satellites for Amazon, its Atlas-5 rocket lifting off from Cape Canaveral in Florida.

As of posting the Kuiper satellites have not yet been deployed. As this was ULA’s first launch this year, the company is not included in the leader board for the 2025 launch race.

49 SpaceX
22 China
5 Rocket Lab
5 Russia

SpaceX now leads the rest of the world in successful launches, 49 to 38. Two more launches are still scheduled for today, one by SpaceX placing more Starlinks into orbit, and a second a classified Angara launch out of its Plesetsk spaceport in northeastern Russia.

Watch Atlas-5 launch of Amazon’s first 27 Kuiper satellties

3:23 pm

I have embedded below the live stream of the launch today of ULA’s Atlas-5 rocket, carrying the first 27 satellites for Amazon’s planned 3,200 satellite Kuiper internet constellation designed to compete directly against SpaceX’s Starlink.

The first launch attempt several weeks ago was scrubbed due to weather. This is one of fifteen Atlas-5’s still in ULA’s inventory, eight of which are reserved for Kuiper launches, six of which are reserved for future missions of Boeing’s manned Starliner capsule, and one of which will place into geosynchronous orbit a communications satellite for Viasat.

After these launches ULA will rely entirely on its new Vulcan rocket.

ULA and Amazon schedule first Kuiper satellite launch for April 9, 2025

9:49 am

The launch of the first 27 satellites in Amazon’s 3,200-plus satellite Kuiper internet constellation has now been scheduled for April 9, 2025, using ULA’s Atlas-5 rocket lifting off from Cape Canaveral.

The Kuiper constellation, intended to compete directly with SpaceX’s Starlink constellation, was first conceived at about the same time as Starlink. Since then — while Amazon moved slowly launching only two test satellites — SpaceX launched thousands and signed up millions of customers, grabbing market share that it will be difficult for Kuiper to re-capture.

The launch will also be the first in 2025 for ULA, which had hoped to do as many as 25 launches this year with its old soon-to-be-retired Atlas-5 and new Vulcan rocket. The six-month delay in getting the Pentagon to finally certify Vulcan for commercial military launches has put a damper on that plan. Right now ULA will be lucky if it can complete half those launches.

ULA pinpoints reason a nozzle fell off a Vulcan rocket side booster during last launch

9:11 am

During a press briefing earlier this week, ULA’s CEO Tory Bruno noted that a manufacturing defect was the reason a nozzle fell off one of the two solid-fueled strap-on boosters during the second launch of the company’s new Vulcan rocket.

In a March 12 media roundtable, Tory Bruno, president and chief executive of ULA, said the anomaly was traced to a “manufacturing defect” in one of the internal parts of the nozzle, an insulator. Specific details, he said, remained proprietary. “We have isolated the root cause and made appropriate corrective actions,” he said, which were confirmed in a static-fire test of a motor at a Northrop test site in Utah in February. “So we are back continuing to fabricate hardware and, at least initially, screening for what that root cause was.”

The company however still awaits approval by the Pentagon to begin Vulcan commercial military launches. That delay has forced it to shift its first launch in 2025 from Vulcan to an Atlas-5 launch of Amazon’s first set of operational Kuiper satellites. Bruno also revealed during the press briefing that the company has scaled down the number of launches it hopes to complete in 2025 from 20 to 12, with the reduction caused almost entirely by fewer Vulcan launches.

ULA swapping Vulcan for Atlas-5 for first 2025 launch

11:18 am

ULA has decided to destack the Vulcan rocket it had planned as its first launch in 2025 (launching a military payload) and is now replacing it with one of its remaining Atlas-5 rockets to put the first batch of satellites for Amazon’s Kuiper internet constellation.

It appears the military is not ready to certify this launch after the second Vulcan launch in October 2024 experienced a problem with one of its strap-on boosters. The payload got to its proper orbit, but the loss of that booster’s nozzle appears to be an issue the military remains concerned about.

Rather than wait, ULA decided to switch to the Kuiper launch. The company wants to complete up to 20 launches in 2025, many of which are for Amazon using its last ten or so Atlas-5 rockets. When it can start commercial launches of Vulcan remains somewhat uncertain. The military has indicated it will make a final decision of certification in the spring, and has also said that first operational flight will follow soon after.

ULA’s big plans for 2025

12:31 pm

As ULA prepares for the second launch of its new Vulcan rocket, presently scheduled for launch tomorrow at 6 am (Eastern), it held a press briefing on October 2, 2024 to provide an update on the rocket’s present and future status.

The key takeaways, assuming this launch succeeds as planned, as noted in a tweet by reporter Jeff Foust from Space News:

  • ULA still plans on completing two national security Vulcan flights before the end of the year
  • It is targeting 20 launches in 2025, half with Vulcan and half with Atlas-5
  • The first Atlas-5 launch of Amazon’s Kuiper satellites won’t happen until 2025
  • When Sierra Space says Dream Chaser is ready, ULA will launch it

Completing three Vulcan launches in the next three months will almost match the four launches the company has so far completed in the first nine months of the year. Furthermore, considering that ULA’s previous record for launches in a single year is 16, set in 2009, and that the company has not completed more than ten launches in a year since 2016, these plans are very ambitious indeed.

If it succeeds however in just getting close to these numbers, ULA will be doing very well indeed.

ULA completes its 4th launch this year and last Atlas-5 launch for the Space Force

9:10 am

Though ULA’s Atlas-5 rocket still has a number of launches on its manifest before it is retired, early this morning the company successfully completed the last Atlas-5 launch for the Space Force, the rocket lifting off from Cape Canaveral in Florida.

This was ULA’s fourth launch in 2024, the most in a year for the company since 2022. The leader board for this year’s launch race remains unchanged:

74 SpaceX
31 China
8 Rocket Lab
8 Russia

American private enterprise however now leads the rest of the world combined in successful launches 87 to 47, while SpaceX by itself still leads the entire world combined, including American companies, 74 to 60.

Note: A Rocket Lab that had been scheduled for today has been delayed two days.

ULA’s Atlas-5 launches Boeing’s Starliner capsule on its first manned mission

9:17 am

After many delays and scrubs involving both the rocket and the capsule, ULA’s Atlas-5 rocket today successfully launched Boeing’s Starliner capsule on its first manned mission, carrying NASA astronauts Butch Wilmore and Suni Williams.

I have embedded the live stream below, cued to just before liftoff. The spacecraft will dock with ISS tomorrow, where Wilmore and Williams will spend a week checking out the capsule’s operations before undocking and returning to Earth.

As this was only the third launch this year for ULA, the leader board for the 2024 launch race doesn’t change:

59 SpaceX
26 China
8 Russia
7 Rocket Lab

American private enterprise now leads the world combined in successful launches, 69 to 40, while SpaceX by itself leads the entire world, including other American companies, 59 to 50.

NASA confirms June 5th as new launch date for Starliner

8:33 am

NASA yesterday evening confirmed that the agency, ULA, and Boeing are now targeting June 5, 2024 at 10:52 am (Eastern) for the launch of the first manned launch of Boeing’s Starliner capsule carrying two astronauts to ISS for a two week checkout mission.

Technicians and engineers with ULA (United Launch Alliance) worked overnight and on Sunday to assess the ground support equipment at the launch pad that encountered issues during the countdown and scrubbed the June 1 launch attempt. The ULA team identified an issue with a single ground power supply within one of the three redundant chassis that provides power to a subset of computer cards controlling various system functions, including the card responsible for the stable replenishment topping valves for the Centaur upper stage. All three of these chassis are required to enter the terminal phase of the launch countdown to ensure crew safety.

On Sunday, the chassis containing the faulty ground power unit was removed, visually inspected, and replaced with a spare chassis. No signs of physical damage were observed. A full failure analysis of the power unit will be performed to better understand root cause. Meanwhile, ULA has completed functional checkouts of the new chassis and the cards, and all hardware is performing normally.

These kinds of technical issues happen too often on ULA launches. Company engineers always fix them, but it never appears they fix them permanently. Too often on launches they pop up again, causing more scrubs.

The goal should be to fix them so they never pop up again, and your launches can begin to launch reliably, on time. And we know it can be done, because SpaceX has done it.

Boeing Starliner launch scrubbed at T-3:50

10:10 am

UPDATE: The launch is now scheduled for June 5, 2024 at 10:52 am (Eastern).

For reasons that appeared related to the ground system’s of ULA’s Atlas-5 rocket, the first manned launch of Boeing’s Starliner’s capsule was scrubbed today at T-3:50.

It appears they want to try again tomorrow at 12:03 pm (Eastern), assuming ULA can figure out what happened.

The repeated scrubs and delays that have so far prevented this launch are beginning to remind my of my childhood watching the early NASA launch attempts during the Mercury program. Then, they hadn’t done this before, and were being very careful about everything.

Now, it seems that NASA, ULA, and Boeing are acting the same way, and that is probably because they are very nervous about Starliner and don’t want anything to go wrong.

I had intended to embed the live stream, but slept late (it IS the weekend, y’know). Sorry.

Watching the first manned launch of Boeing’s Starliner capsule

9:31 am

NASA has now announced the broadcast schedule for tomorrow’s 12:35 pm (Eastern) launch of Boeing’s Starliner capsule on its first manned mission to ISS.

NASA will provide live coverage of prelaunch and launch activities for the agency’s Boeing Crew Flight Test, which will carry NASA astronauts Butch Wilmore and Suni Williams to and from the International Space Station.

Launch of the ULA (United Launch Alliance) Atlas V rocket and Boeing Starliner spacecraft is targeted for 12:25 p.m. EDT Saturday, June 1, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Starliner will dock to the forward-facing port of the station’s Harmony module at approximately 1:50 p.m., Sunday, June 2.

The live stream will begin on NASA TV at 8:15 am (Eastern). I will embed that live stream here tomorrow. As this start time is more than four hours before launch, expect there to be endless NASA propaganda for most of that time. My advice is to tune in at around noon.

Let us all pray that all goes well on this flight. Boeing’s recent track record has generally be horrible. We can only hope its engineers have gotten all of the kinks out of this capsule.

NASA/Boeing/ULA confirm new June 1st launch date for Starliner

9:36 am

In a press briefing this morning officials from NASA, Boeing, and ULA confirmed the new June 1, 12:25 pm (Eastern) launch date for the first manned flight of Boeing’s Starliner manned capsule.

The officials provided a more detailed explanation of the helium leak in a valve that effects the capsule’s service module attitude thruster system, noting that it is not a design flaw but some specific issue in this particular valve. Because of this, they are confident the system can function safely even with the leak, which is relatively small.

However, the officials also noted that during their reviews in the past two weeks they discovered a new software issue in the spacecraft’s de-orbit engines that — under very unusual and unlikely circumstances — could actually cause those engines to fail to operate. They have figured out a work-around, whereby they fire the engines at a lower thrust in two stages rather than once.

Should the launch on June 1st be scrubbed for weather, they have back up dates on the next few days, though by June 4th ULA might have to swap out batteries on its Atlas-5 rocket that will require a longer stand down of several additional days.

Boeing/NASA now targeting a June 1, 2024 launch of Starliner

9:28 am

In a brief update posted today by NASA, the agency announced that Boeing, NASA, and ULA have a new 12:25 pm (Eastern) June 1, 2024 launch date for the first manned flight of Boeing’s Starliner capsule.

The announcement was incredibly obscure about what the issues are that have caused this additional week delay:

Work continues to assess Starliner performance and redundancy following the discovery of a small helium leak in the spacecraft’s service module. As part of this work, and unrelated to the current leak which remains stable, teams are in the process of completing a follow-on propulsion system assessment to understand potential helium system impacts on some Starliner return scenarios. NASA also will conduct a Delta-Agency Flight Test Readiness Review to discuss the work that was performed since the last CFT launch attempt on May 6, and to evaluate issue closure and flight rationale ahead of the next attempt, as part of NASA’s process for assessing readiness. The date of the upcoming Flight Test Readiness Review is under consideration and will be announced once selected.

It appears that engineers are worried the leak — which is linked to one of the attitude thrusters in the capsule’s service module — might impact the ability of Starliner to return to Earth safely. It also appears there is concern about the spacecraft sitting on the launchpad for more than a month, and an evaluation is on-going on whether this might be an issue as well.

I am guessing however. A more detailed explanation might be forth-coming after press update scheduled for 11 am (Eastern) tomorrow.

Starliner manned launch delayed again; no new launch announced

9:33 am

In a very terse statement that apparently was only sent out by email to some sources, NASA and Boeing announced last night that the May 25, 2024 launch of the first manned Starliner mission on ULA’s Atlas-5 rocket had been postponed, with no new launch date set.

NASA, Boeing, and ULA are foregoing the Saturday, May 25 launch attempt for NASA’s Boeing Crew Flight Test. The team has been in meetings for two consecutive days, assessing flight rationale, system performance, and redundancy. There is still forward work in these areas, and the next possible launch opportunity is still being discussed.

NASA will share more details once we have a clearer path forward,

The first launch scrub prior to the first launch date of May 6th was due to a valve issue on the Atlas-5 rocket. ULA quickly replaced that valve and the launch was rescheduled for May 17th. Then Boeing engineers detected a helium leak related to one of the attitude thrusters in the capsule’s service module. The launch was first delayed until May 21st, then delayed again until May 25th. Now it is delayed indefinitely.

Whether that helium leak remains the cause of this new delay remains unknown. That no new launch date has been proposed suggests the need to bring the rocket and capsule back to the assembly building to destack it in order to fix the problem. That NASA, Boeing, and ULA are being so coy about revealing any details suggests however that some additional issue might have been uncovered.

Regardless, this new extended delay is very bad publicity for Boeing. While the comparison is somewhat unfair, it continues to make Starliner look like an American version of a Yugo, not the kind of vehicle one would nonchalantly climb into for a flight into space.

Starliner launch delayed again, to May 25, 2024

3:36 pm

Boeing, ULA, and NASA have decided to delay the first manned flight of Boeing’s Starliner capsule another four days to 3:09 pm (Eastern) on May 25, 2024.

The additional time allows teams to further assess a small helium leak in the Boeing Starliner spacecraft’s service module traced to a flange on a single reaction control system thruster. Pressure testing performed on May 15 on the spacecraft’s helium system showed the leak in the flange is stable and would not pose a risk at that level during the flight. The testing also indicated the rest of the thruster system is sealed effectively across the entire service module. Boeing teams are working to develop operational procedures to ensure the system retains sufficient performance capability and appropriate redundancy during the flight.

It appears they simply want to give themselves extra time to review their data thoroughly, with no rush, before lighting the rocket.

Atlas-5 launch of Starliner slips to May 21, 2024

1:25 pm

While ULA has successfully replaced the valve in the upper stage of the Atlas-5 rocket, the first manned launch of Boeing’s Starliner capsule has slipped another four days, to May 21, 2024, because a newly discovered helium leak in the capsule’s service module.

Starliner teams are working to resolve a small helium leak detected in the spacecraft’s service module traced to a flange on a single reaction control system thruster. Helium is used in spacecraft thruster systems to allow the thrusters to fire and is not combustible or toxic.

NASA and Boeing are developing spacecraft testing and operational solutions to address the issue. As a part of the testing, Boeing will bring the propulsion system up to flight pressurization just as it does prior to launch, and then allow the helium system to vent naturally to validate existing data and strengthen flight rationale.

The prevous launch scrub was entirely due to the ULA’s rocket, not anything related to Boeing. This delay however is a Boeing issue, and it only reinforces the general uneasiness everyone feels about Boeing’s quality control work.

Launch of first manned flight of Starliner rescheduled for May 17, 2024

9:31 am

Because ULA engineers have decided they need to replace the valve that forced a launch scrub on May 8th, the first manned launch of Boeing’s Starliner capsule to ISS has now been rescheduled to May 17, 2024.

The oscillating behavior of the valve during prelaunch operations, ultimately resulted in mission teams calling a launch scrub on May 6. After the ground crews and astronauts Butch Wilmore and Suni Williams safely exited from Space Launch Complex-41, the ULA team successfully commanded the valve closed and the oscillations were temporarily dampened. The oscillations then re-occurred twice during fuel removal operations. After evaluating the valve history, data signatures from the launch attempt, and assessing the risks relative to continued use, the ULA team determined the valve exceeded its qualification and mission managers agreed to remove and replace the valve.

Replacing the valve is a somewhat routine procedure, but it will take a few days, causing the two-week delay.

Starliner launch scrubbed due to valve issue

9:21 am

Yesterday’s Starliner launch was scrubbed before launch because ULA had detected an issue with a valve on the Atlas-5’s Centaur upper stage, causing that valve to flutter because it had not closed in the proper position.

At the press conference that followed, ULA’s CEO Tory Bruno explained that during an unmanned launch, engineers would have simply cycled the valve, which almost always works to get it to seat properly. ULA launch rules however forbids it from doing so on a manned launch, because that would be the equivalent of fueling the tank with people on board the rocket. The Atlas-5 was initially not built for manned flights, and though it has been upgraded to man-rate it, those upgrades did not permit ULA this capability, unlike SpaceX’s Falcon 9, which get fueled entirely after the crew boards Dragon.

They are reviewing the data to see if the valve will need to be replaced. If not, the launch could happen quickly. If it does, the launch will be delayed slightly longer, but not significantly. Right now ULA, NASA, and Boeing are targeting a May 10th launch.

It is worth listening to Tory Bruno’s explanation of the situation because of its clarity. I have embedded his comments below, time-stamped to when he began speaking.

NASA announces launch coverage for the first Starliner manned capsule launch on May 6, 2024

10:23 am

NASA today released the details for its public media coverage of the first manned launch at 10:34 pm (Eastern) on May 6, 2024 of Boeing’s Starliner capsule.

NASA will provide live coverage of prelaunch and launch activities for the agency’s Boeing Crew Flight Test, which will carry NASA astronauts Butch Wilmore and Suni Williams to and from the International Space Station.

Launch of the ULA (United Launch Alliance) Atlas V rocket and Boeing Starliner spacecraft is targeted for 10:34 p.m. EDT Monday, May 6, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. The flight test will carry Wilmore and Williams to the space station for about a week to test the Starliner spacecraft and its subsystems before NASA certifies the transportation system for rotational missions to the orbiting laboratory for the agency’s Commercial Crew Program.

Starliner will dock to the forward-facing port of the station’s Harmony module at 12:48 a.m., Wednesday, May 8.

Though that coverage includes several prelaunch and post launch press conferences, the key coverage of the launch itself will begin at 6:30 pm (Eastern) on May 6th, about four hours before the launch itself. It will also include the capsule’s docking with ISS on May 8th.

I will embed NASA’s Youtube live stream here on Behind the Black on both dates, though as always I sugggest waiting until just before launch and docking to tune in. The four hours of streaming prior to launch is mostly going to be NASA propaganda, touting the agency and often misconstruing the facts to overstate its importance. This launch will be just like SpaceX’s Dragon launches, in that almost everything will be run by the two private companies involved, Boeing and ULA, and not NASA. NASA’s real involvement will only begin at the docking to ISS.

This first manned flight of Starliner is long past due. It was supposed to occur about four years ago, but numerous technological and management problems at Boeing forced many delays. Getting that capsule operational will finally give NASA two American companies capable of putting humans in space. It will also offer some competition to SpaceX, though this competition will be weak until Boeing can demonstrate Starliner’s reliability.

ULA begins stacking Atlas-5 rocket for launching the first manned mission of Starliner

9:26 am

ULA has begun to assemble the Atlas-5 rocket that will hopefully launch Boeing’s Starliner capsule on its first manned mission to ISS, presently targeting a late April lift-off.

The rocket’s main stage was transferred from the nearby Advanced Spaceflight Operations Center to the integration facility Wednesday, Feb. 21, where it will await integration with the rocket’s upper Centaur stage and Starliner. The spacecraft will carry NASA astronauts Suni Williams and Butch Wilmore to the orbiting laboratory for a short stay of about one to two weeks before returning to a landing site in the southwest United States.

The late April date appears to be a slight delay from previous announcements.

Amazon files to have shareholder lawsuit dismissed

9:15 am

On December 11, 2023 Amazon requested dismissal of a shareholder lawsuit against it for acting in bad faith by excluding SpaceX in its initial launch contracts with ULA, Arianespace, and Blue Origin to put its Kuiper constellation of satellites into orbit.

The lawsuit claimed that the board performed little diligence on the proposed contracts to launch the 3,236-satellite constellation with the Ariane 6, New Glenn and Vulcan Centaur rockets. The combined contracts were, it stated, the second largest capital expenditure in Amazon’s history at the time, trailing only its $13.7 billion acquisition of grocer Whole Foods.

The lawsuit stated that the board and its audit committee spent “barely an hour” reviewing those contracts, including those that would go to Blue Origin and ULA. Blue Origin is owned by Amazon founder and former chief executive Jeff Bezos, while ULA has a contract with Blue Origin to use BE-4 engines on its Vulcan rocket. The suit estimated that nearly 45% of the value of the contracts goes to Blue Origin either directly or through the BE-4 engine contract with ULA.

Amazon’s call for dismissal disputes these claims, stating that the board spent far more time on the issue, and then documents this. Interestingly, it makes no mention of the recent additional launch contract Amazon signed with SpaceX on December 3, 2023, but it is obvious that this filing was timed to occur afterward in order to strengthen Amazon’s case.

Amazon’s response (available at the link above) is heavily redacted, so some of the company’s claims are difficult to assess. For example, if the board did consider the issue of launch contractors properly, the subject of using SpaceX should have come up and been discussed at length. The redactions make it impossible to determine if this was so. If anything, what can be read suggests SpaceX was dismissed as an option far too quickly.

ULA’s Atlas-5 rocket launches first two Kuiper satellites

11:16 am

ULA’s Atlas-5 rocket today successfully launched the first two prototype satellites of Amazon’s proposed 3,200-satellite constellation to provide broadband globally in competition with Starlink and OneWeb.

As of posting, the satellites had not yet deployed, with the rocket’s upper stage still firing its engines to bring the rocket to its proper orbit. The live stream unfortunately ended early at this point.

Though the Atlas-5 is being retired, to be replaced by ULA’s still unlaunched Vulcan rocket, about seventeen rockets remain in the company’s launch manifest. All have payloads, so any additional ULA launch contracts must rely on Vulcan.

This was ULA’s third launch in 2023, so it does not change the leader board for the 2023 launch race. The company predicted it would complete ten launches in 2023, a prediction that with less than three months left in the year seems unlikely for it to achieve.

70 SpaceX
45 China
13 Russia
7 Rocket Lab
7 India

American private enterprise now leads China in successful launches 82 to 45, and leads the entire world combined 82 to 72. SpaceX by itself still trails the rest of the world, excluding American companies, 70 to 72.

Two launches today, one by ULA and one by China

10:16 am

Today there were two successful launches. First China launched a remote sensing satellite using its Long March 6 rocket that lifted off from its Taiyuan spaceport in the south of China.

No word on where the rocket’s lower stages and four strap-on boosters crashed inside China.

Shortly thereafter, ULA used its Atlas-5 rocket to place a reconnaissance satellite into orbit for the National Reconnaissance Office (NRO), lifting off from Cape Canaveral.

For ULA, this was only its second launch in 2023. The leaders in the 2023 launch race are now as follows, with China’s total corrected:

63 SpaceX
42 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise now leads China in successful launches 73 to 42. It also now leads the entire world combined, 73 to 67, while SpaceX by itself now trails the rest of the world (excluding American companies) only 63 to 67.

CORRECTION: Hat tip to reader John Foley (see his comment below), who noted that China’s total appeared to be one short. I went back and discovered I had missed a March 22, 2023 launch of a Kuaizhou 1A rocket from the Jiujian spaceport, placing four weather satellites in orbit. I have now added that launch to China’s total, and corrected the other numbers.

Starliner’s first manned mission to ISS delayed again

9:36 am

According to a tweet by a NASA official, the first manned mission to ISS of Boeing’s Starliner capsule, carrying two NASA astronauts, has been delayed again, from the planned late April launch to sometime during the summer.

No reasons for the delay were given, as yet. The second link notes however that a schedule conflict at ULA, which is launching Starliner on its Atlas-5 rocket, might be part of the reason.

A launch in late April [of Starliner on the Atlas-5] would have put it in conflict with the inaugural launch of United Launch Alliance’s Vulcan Centaur rocket, currently scheduled for as soon as May 4. Vulcan and Atlas use the same launch pad at Cape Canaveral Space Force Station, and ULA has been conducting tests of the Vulcan rocket on that pad. It has not shared updates on the status of the Atlas 5 used for Starliner.

This conflict might also explain why Starliner itself has not yet been fueled, since Boeing officials have said they want to do this within 60 days of launch to avoid the same kind of valve leaks that delayed the second unmanned demo mission for almost a year.

Starliner itself is years behind schedule, a long delay that has cost Boeing an enormous amount of income. First, the problems during the first unmanned demo flight in December 2019 forced the company to do a second unmanned demo flight, on its own dime costing about $400 million. That second flight was then delayed because of those valve issues. All the delays next cost Boeing income from NASA, as the agency was forced to purchase many manned flights from SpaceX that it had intended to buy from Boeing.

ULA closing facility in Texas that makes parts for the retiring Atlas-5 rocket

3:42 pm

ULA has announced that it is shutting down its facility in Harlingen, Texas, that makes parts for the company’s soon-to-be retired Atlas-5 rocket.

The facility will shut down at the end of this year, with a loss of about 100 jobs.

This closure is actually a very positive sign for ULA. It indicates that it is streamlining its operations. For example, construction of the Vulcan rocket that replaces the Atlas-5 is all done in Alabama. One of the reasons Atlas-5 cost so much was the widespread distribution of its ULA facilities, probably done to satisfy congressional demands.

With Vulcan, ULA has instead been much more focused on making it less expensive so it can compete with SpaceX. Thus, it simplified its construction, putting everything in Alabama. (Choosing Alabama was likely to satisfy the most powerful senator at the time, porkmeister Richard Shelby (R-Alabama), who has now retired.)

Two die at Northrop Grumman facility that makes solid rocket boosters

2:21 pm

Two individuals died last night from an as-yet unknown cause at the Northrop Grumman Bacchus facility in Utah that makes solid rocket strap-on boosters for ULA’s rockets.

Further details about what exactly led to the deaths and who died were not made available.

The West Valley City Fire and Police Departments said they responded to the Bacchus facility after the two employees were found unconscious. Crews attempted life-saving measures and transported the two employees to the hospital, where they later died.

An investigation into the incident is ongoing by the Occupational Safety and Health Administration (OSHA).

Depending on circumstances, delivery of strap-on boosters for upcoming Atlas-5 and Vulcan launches could be impacted.
