Blue Origin completes first static fire test of New Glenn upper stage

9:23 am

Blue Origin yesterday successfully conducted a 15 second static fire test of the upper stage of its orbital New Glenn rocket.

The hotfire lasted 15 seconds and marked the first time we operated the vehicle as an integrated system. The purpose of the hotfire test was to validate interactions between the subsystems on the second stage, its two BE-3U engines, and the ground control systems.

Additionally, we demonstrated its three key systems, including: the tank pressurization control system, which uses helium to pressurize the liquid hydrogen and liquid oxygen tanks during flight; the thrust vector control system, which gimbals the engines and steers the rocket during flight; and validated the start-up and shut-down sequences for the BE-3U systems, which can be restarted up to three times during a mission.

In addition to testing our flight hardware, this hotfire test was also an opportunity for the launch operations team to practice launch day procedures on console and verify timing for a number of critical operations.

An actual launch date has not been announced. Previously New Glenn was to carry two Mars orbiters for NASA and launch by October 21, 2024 at the latest. Because of doubts the company could meet that data, NASA pulled the satellites from the rocket.

Prior to launch the company still has to do a full static fire test of the rocket’s first stage. Though company officials have said this would happen “very soon,” no date has been announced for the test.

China launches eight satellites from offshore barge

9:16 am

China's spaceports

China today successfully launched eight satellites, its Smart Dragon-3 rocket lifting off from an offshore barge off the northeast coast of China.

The reports from China’s state-run press provided no information on the satellites themselves. The rocket has four stages that are all solid-fueled. This was its fourth launch from the off-shore barge. It was also thirteenth total offshore launch for China, involving four different rockets.

The leaders in the 2024 launch race:

93 SpaceX
42 China
11 Russia
11 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 109 to 64, while SpaceX by itself now leads the entire world, including American companies, 93 to 80.

More deterioration to Curiosity’s worst wheel

12:13 pm

Comparison of changing damage from Feb to Sept 2024
For original images go here, here, and here.

The science team for the Curiosity Mars rover on September 22, 2024 did another survey of its damaged wheels using the close-up camera on the end of the rover’s arm, and though most of the pictures appear to show the situation remains stable, the one wheel that has consistently shown the worst damage now shows some additional deterioration since February 2024.

To the right are comparison pictures, with the February 2024 picture on top and two new September 22, 2024 images showing the same damaged area, though from a different angle, on the bottom. (The technical captions for the bottom images can be found here and here.) I have labeled the treads, dubbed growsers, to make it easier to understand how the pictures all line up.

Previous images have looked down at the large damaged area from growsers 1 to 4, and since it was first spotted in 2022 showed it to be growing, but very slowly. The new pictures show that same damaged area from the side, which reveals that the zig-zag divider between growser #3 and growser #4 has now collapsed, so that this whole damaged area is now a major depression, as indicated by the two arrows.

Overall, the rover’s wheels appear to surviving the rough terrain of the foothills of Mount Sharp, though it is clear that care must continue to be taken to extend their life for as long as possible. That the rover has six wheels gives it a lot of redundancy, so that even if this one wheel eventually fails the rover will likely be able to continue to rove, but with some limitations. This wheel is the left middle wheel, which is helpful, as it is less necessary than the four corner wheels. [Update: According to a rover update today, this wheel is the right middle wheel, which contradicts an earlier report which described this as the left middle wheel. I note this contradiction for accuracy.]

Isar begins static fire tests of its Spectrum rocket

9:44 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

Isar Aerospace, one of three German rocket startups vying to the be first to complete an orbital launch, has now revealed that it has begun static fire tests of its Spectrum rocket at its launch facility at the Andoya spaceport in Norway.

In response to questioning from European Spaceflight, Isar confirmed that all components of the Spectrum rocket that will be utilized for its inaugural flight had arrived in Andøya and that testing of the first and second stages had begun.

“All components of our launch vehicle Spectrum have arrived in Andøya and the final preparations for the first test flight of Spectrum are in full swing,” an Isar Aerospace spokesperson said. “We are currently performing hot fire tests of the first and second stages. These tests will determine whether the systems meet all the necessary requirements for the first test flight.”

The company has a 20-year lease at Andoya, and though it has not announced a launch date, these ground tests suggest that launch could occur quite soon. If so, Isar will have beaten Rocket Factory Augsburg and Hyimpulse to space. Rocket Factory had apparently been in the lead until a fire during a full static fire test of its RFA-1 rocket’s first stage in August destroyed the rocket.

This race is also between the spaceports surrounding the Norwegian Sea. Rocket Factory is launching from Saxavord in the Shetland Islands, a spaceport that has been under development the longest, since before 2020, and has been plagued with the red tape problems that appear systemic in the United Kingdom. Andoya however is a latecomer in this race. Though it has been used for suborbital tests for decades, it only started its effort to become a commercial spaceport for orbital flights in November 2023, less than eleven months ago.

New Russian missile explodes during test

9:29 am

According to orbital imagery, it appears that a new Russian missile that has been under development for more than a dozen years but has not yet completed a full test flight, exploded sometime between September 20th and September 21st during a test launch.

Satellite images from Planet Labs of the Sarmat’s Yubileinaya launch silo in Plesetsk posted on Sept. 21, 2024, showed a major crater left by an apparent rocket explosion, along with multiple fires just east of the site. The fires were also confirmed by NASA’s satellite-based Fire Information for Resource Management System, FIRMS, within 24 hours of Sept. 21, 2024. At least four fire engines speeding to the facility were also discernable on satellite images, confirming that these pictures had been taken immediately after the incident on September 21.

The rocket’s development — which claims will be far more capable than its present missiles — appears to have been plagued with problems and delays. It is also a strange missile, in that it is liquid-fueled, something that western militaries abandoned for missiles more than a half century ago. Solid-fueled missiles are simpler and can be stored ready-to-launch for long periods. Fueling and launching a liquid-fueled rocket quickly is not really practical during a wartime emergency.

SpaceX conducting salvage operations to recover a Superheavy booster in the Gulf of Mexico

9:19 am

SpaceX has apparently conducted salvage operations in the Gulf of Mexico to recover the Superheavy booster that had successfully completed a soft vertical splashdown during the fourth Starship/Superheavy test flight on June 6, 2024.

Confirmation of the recovery project came from a group of young, independent filmmakers who caught wind of the operation and chartered a boat for the 15-mile trip to the Ridgewind to see for themselves what was going on.

…After a two-and-a-half-hour cruise they were about a half mile from the Ridgewind when a drone buzzed toward them. It hovered for a moment before a voice announced through a loudspeaker: “There is a one mile exclusion zone in this area, please depart one mile away from vessel.”

The filmmakers retreated as requested, but then remained there for awhile, observing operations from a distance. They later contacted SpaceX.

The Interstellar Gateway crew reached out to SpaceX, which Leal said quickly confirmed it had contracted with Hornbeck to recover the giant booster. It asked the filmmakers to refrain from announcing the find until after the Ridgewind completed its work and began steaming to port. That happened Sunday.

The filmmakers are one of the number of independent live stream groups that record launches, and made it clear it announcing the salvage work that they respected SpaceX’s request because they knew it was entirely reasonable — to avoid safety problems that could be caused by others boating over — and that they had no desire to hinder SpaceX’s effort.

The article, from a mainstream Democratic Party propaganda source, however tried to slam SpaceX for its “secretive nature,” something that is so untrue only a Democrat shill could write it with a straight face. It also spent a lot of time criticizing the company for creating that one-mile safety exclusion zone around its salvage operations, questioning SpaceX’s “authority” to do so.

Chinese pseudo-company almost succeeds in vertically landing test rocket

9:00 am

The Chinese pseudo-company Deep Blue Aerospace this weekend almost succeeded in vertically landing a grasshopper-type test rocket, its engines cutting off just before landing so that when the rocket hit the ground the impact was too much for its landing legs.

I have embedded video of the flight and crash landing below. The footage has a AI feel to it, for several reasons. First the camera is a fisheye lens, creating distortion. Second, this test grasshopper-type rocket is quite small, much smaller than the company wants you to realize, thus allowing the drone to fly around during its flight it in a somewhat spectacular manner.

The company stated that the test completed 10 of 11 engineering goals. It will have to rebuild a new test lander however to achieve that last and most important goal, landing without damage to allow immediate reflight. Regardless, this test means that China is finally getting close to achieving rocket reusablity, something it promised in 2018 it would achieve by 2020.

Note also that though this pseudo-company will likely not release its data to the other Chinese pseudo-companies, if China’s government wants to expropriate it for its own government rockets it will do so, and in fact likely has.

China and Rocket Lab complete launches

3:11 pm

Yesterday there were two more launches. First China’s Long March 2D rocket in the very early morning hours lifted off from its Taiyuan spaceport in northern China, placing six satellites in orbit.

The satellites are part of a constellation for doing high resolution Earth observations. No word on where the rocket’s lower stages, using very toxic hypergolic fuel, crashed inside China.

Next Rocket Lab successfully launched five satellites for the French satellite company Kinéis. This was the second of five planned launches by Rocket Lab to put the entire 25 satellite internet-of-things constellation into orbit. It was also the second attempt to launch, with the first experiencing a launch abort at T-0 seconds due to a ground-system issue.

The launch pace is beginning to heat up. There were four launches yesterday, two from China, one from SpaceX and one from Rocket Lab. The leaders in the 2024 launch race:

93 SpaceX
41 China
11 Russia
11 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 109 to 63, while SpaceX by itself now leads the entire world, including American companies, 93 to 79.

Boeing replaces the head of its defense/space/security division

4:24 pm

Ted Colbert
Ted Colbert

Boeing today announced that the head of its defense/space/security division, Ted Colbert, has been removed, effective immediately.

New Boeing CEO Kelly Ortberg in his first significant move since taking over in August, said Ted Colbert would be leaving and Steve Parker, the unit’s chief operating officer, would assume Colbert’s responsibilities until a replacement is named at a later date.

One project that Colbert was in charge of was Starliner, a program that has cost the company at least $1.6 billion in overruns because of numerous faulty engineering problems.

Colbert might not be to blame for the endless problems at Starliner, but the fish stinks from the head. He also might be very qualified, but sadly, as his picture shows, he is a minority, and since Boeing went all in on DEI racist hiring quotas a few years ago, which makes the skin color and gender of an applicant a major qualification in hiring, one can’t help wondering if he was a DEI (Didn’t Earn It) hire. At Boeing that policy created a goal to increase black staffing by 20%. Its full report [pdf] makes it very clear it no longer made talent, experience, or skill the primary qualification for getting hired, but skin color and sex took precedence.

As I said, one cannot help wondering if Colbert was hired not because of his great management and engineering knowledge, but because he happened to born with a dark skin color. If so, that might help explain the failures in this paricular division.

China’s solid-fueled Kuaizhou-1A rocket launches four satellites

4:05 pm

China this afternoon launched four satellites using its solid-fueled Kuaizhou-1A rocket, lifting off from its Xichang spaceport in the southwest of China.

It is unclear what the satellites purpose are, though there are hints they are part of a constellation providing communications for the internet of things. No word was also released where the rocket’s lower stages crashed in China.

The leaders in the 2024 launch race:

93 SpaceX
40 China
11 Russia
10 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 108 to 62, while SpaceX by itself now leads the entire world, including American companies, 93 to 77.
