- Tory Bruno, CEO of ULA, explains why Vulcan uses Centaur-4 instead of Centaur-3 for upper stage
He mentions ULA spent $200 million to manufacture Centaur-4. Yet, he still can’t launch the Vulcan rocket without the first stage, and the first stage depends not on his engines, but on Blue Origin’s long delayed and not yet flightworthy BE-4 engine.
- UK bureaucracy questions Viasat’s takeover of Inmarsat
I covered this in August, but now the UK’s Competition and Markets Authority (CMA) is setting a deadline, October 13, for the companies to explain why their merger won’t destroy Starlink. Otherwise it will initiate a full probe, blocking the merger.
Typical government stupidity. There is no way this merged company will destroy Starlink. If anything, these companies are merging to survive the competition from Starlink.
- China’s second lunar sample return mission, Chang’e-6, targeting a mid-2024 launch
It plans to collect samples from the Moon’s far side.
- Russians are targeting October 12, 2022 for Proton rocket launch
This will be the first Proton launch since December ’21.
- SpaceX scrubs commercial launch today, reschedules for tomorrow
The decision was made about 30 minutes before launch, and is attributed to a desire to provide time to do more checkouts of the rocket.
Thick flow exiting dramatic canyon on Mars
Click for full image.
Cool image time! The photo to the right, cropped and reduced to post here, was taken on July 24, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as a “viscous flow” that has apparently carved the wide curving canyon as it slowly flows into open country to the south.
I would estimate the height of that canyon wall to be around 3,000 feet, though this is a very rough guess. I also image a trail switchbacking up the nose of that canyon wall would make for a truly stupendous hiking experience.
The flow filling the canyon floor appears very glacial, which is not surprising as this canyon is at 37 degrees north latitude, in the mid-latitude band where many glacial features are found. The overview map below provides some more detailed context.

China’s Long March 11 launches from floating sea platform
China today successfully launched two “navigation satellites” from a floating sea platform in the Yellow Sea, using its Long March 11 rocket.
The platform was only about two miles off shore at launch, so the view from the beach drew a large crowd. Video at the first link.
The leaders in the 2022 launch race:
45 SpaceX
42 China
12 Russia
8 Rocket Lab
7 ULA
American private enterprise still leads China 65 to 42 in the national rankings, and the entire globe combined 65 to 62. These numbers will change again later today, with a SpaceX commercial launch scheduled for 4:06 pm (Pacific).
Today’s blacklisted American: Black playwright blackballed because he honestly told the story of racism in the Jim Crow south
Carlyle Brown, censored for writing truthfully
The modern dark age: Close-minded students at the black student association at Texas Wesleyan University have forced the cancellation of a play celebrating the civil rights movement in Mississippi in the 1960s — written by black author Carlyle Brown — because it included realistic dialogue of the time, including the word “nigger”.
Students objected to the use of the n-word in a play that tries to capture the environment of hate and racism of the period. Texas Wesleyan’s Black Student Association declared the reference to be harmful and “triggering.” Calling for a boycott, the Association declared that allowing the play to be heard would “further hurt Black students and possibly students from other marginalized communities.”
The Rambler student newspaper reported that school and theater officials killed the production after a 90-minute campus discussion: “The main concern the students voiced was the ‘triggering’ effect of using the racially explicit word, which is repeated 11 separate times throughout the play, and how it can cause trauma to the black students in the audience.”
The play, Down in Mississippi, can be read here [pdf]. From the play’s summary:

Rocket Lab successfully launches NOAA satellite
Capitalism in space: Rocket Lab today successfully used its Electron rocket to place a NOAA satellite into orbit, designed to gather data from ground-based sensors.
This was the company’s eighth successful launch in 2022, the most it has achieved in any single year. No attempt was made to recover the first stage on this launch.
The leaders in the 2022 launch race:
45 SpaceX
41 China
12 Russia
8 Rocket Lab
7 ULA
American private enterprise now leads China 65 to 41 in the national rankings, and the entire globe combined 65 to 61. The 65 successful launches so far this year is now the second most successful American year in rocketry, exceeded only by the 70 launches in 1966. With almost three months left to go in the year, 2022 looks like it will top that record, by a lot.
SpaceX meanwhile has a launch scheduled for later today, after getting scrubbed yesterday at T-30 seconds because of detected minor helium leak.
Endurance docks at ISS
Like clockwork SpaceX’s Endurance capsule successfully docked at ISS yesterday, delivering four astronauts to the station for a six month mission.
The most interesting aspect of this launch and crew is Russian Anna Kikina.
Kikina is the first Russian to fly aboard a U.S. spacecraft in nearly 20 years. She and Rubio were launched under a new agreement between NASA and Roscosmos, the Russian space agency, that ensures at least one astronaut or cosmonaut is always aboard the space station even if a Crew Dragon or Soyuz is forced to depart early, taking its crew with it.
Without the seat-swap arrangement, a medical emergency or some other major problem could leave an all-Russian or all-NASA crew aboard without the expertise to operate the other nation’s systems.
The agreement had been stalled almost entirely by the former head of Roscosmos, Dmitry Rogozin. He is now gone however, sent by Putin to take over the fake occupation government in parts of the Ukraine. It appears his bellicose manner, that caused the loss of a billion dollars in launch contracts with OneWeb, was more than even Putin could handle.
With him gone, the new head of Roscosmos, Yuri Borisov, quickly finalized this astronaut barter deal. He has also publicly acted to try to ease tensions between the U.S. and Russian space agencies.
Startup smallsat rocket company signs spaceport deal with Brazil
The new colonial movement: A Canadian startup smallsat rocket company, C6 Launch Systems, has not only signed a spaceport deal with Brazil to build its own launchpad at that country’s Alcantara Space Center, it has also won its first launch customer.
First, the launchpad is for C6’s rocket, which is unnamed and designed to launch cubesats. The company webpage says they are aiming for suborbital flights in 2021 and orbital flights in 2022, but it is unclear if it has launched anything at this point.
Nonetheless, Brazil is very clearly teaming up with C6. The Brazilian air force hired it to build a launch pad, a Brazilian company, Concert Technologies, has awarded it a launch contract.
Concert Technologies S.A. who are developing a new small satellite constellation have signed a a non-exclusive letter of intent to launch three small satellites with C6 Launch. The broad agreement allows for Concert Technologies to schedule more launches to maintain and expand their high-resolution Earth Observation (EO) constellation.
It appears Concert’s satellites will be targeting both the Earth imagery market as well as communications services in the “internet of things.”

- ISRO’s commercial arm, NSIL, to launch 36 OneWeb satellites on GSLV-MK3 rocket second half of October 2022
This will be NSIL’s first commercial launch of India’s GSLV-MK3 rocket, its largest. It will also be the first in OneWeb’s effort to replace the Russia Soyuz-2. SpaceX had signed the first contract with OneWeb after the Ukraine War started, but apparently OneWeb wants to fly first on India’s rocket.
- Second Long March 6A rocket delivered to launch site
This rocket is designed to only need two weeks to prep for flight, so the launch could happen this month.
Martian crater and mesa sculpted by ancient flow
Click for full image.
Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken on June 15, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a crater whose ejecta has been sculpted to the east into a teardrop-shaped mesa by some ancient flow, coming from the west.
The crater itself is located in one of several outflow canyons draining out from the volcanic Tharsis Bulge into the northern lowland plain of Chryse Planitia, the biggest of which is Valles Marineris. This particular canyon is one of the smaller and is dubbed Ravi Vallis.
The overview map below illustrates why many scientists think the flow that shaped this mesa came from a catastrophic flood of liquid water, billions of years ago.
