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.

Glacial tributaries draining south on Mars

2:10 pm

Glacial tributaries draining south on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on March 27, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as a “valley network”, what appears to be several tributaries flowing downhill from the northeast to come together into a larger single flow to the southwest. The elevation drop from the high to the low points in this picture is about 600 feet.

What formed the valleys? This location is at 35 degrees south latitude, so we are almost certainly looking at what appear to be shallow glaciers within those valleys, protected by a thin veneer of dust and debris. It also appears that the stippled surrounding plains might also contain a lot of near-surface ice, also protected by a thin layer of dust and debris. The stippling indicates some sublimation and erosion.

China’s Kuaizhou-11 rocket launches four satellites

9:37 am

China yesterday successfully placed four satellites into orbit, its solid-fueled Kuaizhou-11 rocket lifting off from its Jiuquan spaceport in northwest China.

The only information about the satellites released by China’s state-run press was that one was “an ultra-low orbit technology test satellite,” likely similar to the reconnaissance satellites that Redwire is producing here in the U.S.

The state-run press also made no mention on where the rocket’s lower stages crashed inside China.

The leaders in the 2024 launch race:

52 SpaceX
23 China
7 Russia
5 Rocket Lab

American private enterprise still leads the world combined in successful launches, 59 to 36, while SpaceX by itself still leads the entire world, including other American companies, 52 to 43.

Sierra Space’s Tenacity mini-shuttle arrives at the Cape

9:30 am

Capitalism in space: Sierra Space’s Tenacity Dream Chaser mini-shuttle has finally arrived at the Kennedy Space Center in Florida for its final testing and assembly onto ULA’s Vulcan rocket.

Upon arrival at Kennedy, teams moved Dream Chaser Tenacity to the high bay inside the Space Systems Processing Facility, where it will undergo final testing and prelaunch processing ahead of its launch scheduled for later this year.

…The remaining pre-flight activities at Kennedy include acoustic and electromagnetic interference and compatibility testing, completion of work on the spaceplane’s thermal protection system, and final payload integration.

If all goes right, Tenacity’s first mission will last 45 days, delivery about 7,800 pounds of cargo to ISS, and prove out the reusable mini-shuttle for up to seven more flights to ISS.

ESA narrows Ariane-6 launch date to first two weeks in July

9:24 am

In an announcement today, the European Space Agency (ESA) narrowed the launch window for the first launch of its new Ariane-6 rocket to the first two weeks in July.

It also stated that the final launch date will be revealed in the first week of June, during presentations at an air show in Berlin, Germany.

In the next month the rocket will undergo a full dress rehearsal countdown on the launchpad. It will then be “drained of fuel in preparation” for the actual launch.

This rocket is built and mostly owned by the private consortium ArianeGroup, made up of a partnership of Airbus and Safran, and working in conjunction with ESA. Though Arianespace, ESA’s long time commercial arm, is mentioned as ESA’s “launch service provider” for this launch, it is very clear that it is being pushed aside and will soon become irrelevant. The rocket is four years behind schedule and being entirely expendable it is too expensive to compete in the modern launch market. The member nations of ESA have rejected it, and so they are shifting to a capitalism in space model, whereby they no longer have a government commercial “launch service provider” like Arianespace, but instead buy launch services from competing private European rocket companies.

Europe’s problem is that it will take time to develop these private companies. In the interim it will be forced to use Ariane-6, but likely only for a few years. There are at least five new rocket companies in Europe, with three (Rocket Factory Augsburg, PLD, and Hyimpulse) having already completed their first launch tests.

Solar storms are simply no longer a threat

The sunspot cycle as of May 2024

Today’s Chicken Little Report: When NOAA predicted on May 9, 2024 that a powerful solar flare had erupted from the Sun and was aiming a major solar storm directly at the Earth, the scientists at the federal government’s Space Weather Prediction Center could not help underlining the disaster potential, and were ably aided by the mainstream press. This CNN report was typical:

“Geomagnetic storms can impact infrastructure in near-Earth orbit and on Earth’s surface, potentially disrupting communications, the electric power grid, navigation, radio and satellite operations,” according to the Space Weather Prediction Center. “(The center) has notified the operators of these systems so they can take protective action.”

The center has notified operators in these areas to take action to mitigate the potential for any impacts, which include the possibility of increased and more frequent voltage control problems. Other aspects operators will monitor include a chance of anomalies or impacts to satellite operations and frequent or longer periods of GPS degradation.

And as always, the news report has to end with this warning of doom:

Blue Origin resumes manned suborbital New Shepard flights

9:09 am

Blue Origin yesterday flew its first suborbital New Shepard flight since a failure during an unmanned flight in 2022, flying six passengers on a short ten-minute jump.

This suborbital flight got a lot of press yesterday and today, but I consider these suborbital tourist flights somewhat old news. Had they occurred two decades ago, in the 2000s as promised, they could have helped trigger the commercial space industry. Instead, both Blue Origin and Virgin Galactic took another two decades to get started, and by that time orbital tourist flights were taking place.

There might be money to be made in suborbital hops like this, but the future of space exploration lies elsewhere.

As for Blue Origin, this flight confirms that the company has fixed the nozzle issues that caused the September 2022 launch failure. During ascent just after launch the spacecraft’s abort system activated, sending the New Shepard capsule free from the first stage booster, which subsequently crashed. The capsule landed safely with parachutes.

The investigation then stretched out over more than two years. It remains unclear why it took so long, though the FAA’s regulatory burden appears to have been one factor, with Blue Origin’s own sluggish pace of operations another.

China launches four satellites

8:47 am

China early this morning successfully launched four satellites, its Long March 2D rocket lifting off from its Taiyuan spaceport in the northwest of China.

No further information about the satellites was released. Nor did China’s state-run press provide any information about where the rocket’s lower stages, using toxic hypergolic fuels, crashed within the country.

The leaders in the 2024 launch race:

52 SpaceX
22 China
7 Russia
5 Rocket Lab

American private enterprise still leads the world combined in successful launches, 59 to 35, while SpaceX by itself still leads the entire world, including other American companies, 52 to 42.

Piece from SpaceX Dragon service module falls on Canadian farm

9:12 am

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.

NLRB suspends case against SpaceX

9:04 am

The National Labor Relations Board (NLRB) has agreed to suspend one of its cases against SpaceX while the company’s lawsuit challenging the board’s constitutional authority proceeds.

SpaceX alleged that the NLRB’s in-house enforcement proceedings violate its constitutional right to a jury trial. It also said limits on the removal of the NLRB’s board members and administrative judges violates the Constitution. Amazon, Starbucks, and Trader Joe’s have asserted similar claims in recent months.

A second NLRB case has already been suspended by the federal 5th Court of Appeals, for the same reasons.

SpaceX launches another 23 Starlink satellites

10:50 pm

This bunny never stops. SpaceX today successfully launched 23 more Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage set a new record for reflights, completing its 21st flight after landing on a drone ship in the Atlantic. The company has said it is upgrading these stages to last for 40 launches instead of 20, and this launch clearly is the first step in that direction.

The leaders in the 2024 launch race:

52 SpaceX
21 China
7 Russia
5 Rocket Lab

American private enterprise now leads the world combined in successful launches, 59 to 34, while SpaceX by itself still leads the rest of the world, including other American companies, 52 to 41.

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.
