China launches classified satellites for military remote sensing

10:27 pm

China today successfully launched a set of classified satellites (number classified) for doing military remote sensing, its Long March 6 rocket lifting off from its Taiyuan spaceport in north China.

As usual, China’s state-run press released little information about the satellites, the launch, or where the rocket’s core stage and four strap-on boosters crashed inside China. The report did state the Long March 6 was “modified,” but did not detail how. One wonders if China has done something to improve the rocket’s upper stage, which reaches orbit and has had a tendency to break up shortly thereafter, creating large clouds of space junk.

The leaders in the 2025 launch race:

55 SpaceX
24 China
5 Rocket Lab
5 Russia

SpaceX still leads the rest of the world in successful launches, 55 to 41.

Crash prediction for Venera failed lander now reduced to four hours

8:24 am

Venera reentry prediction
Click for original image.

UPDATE: According to several reports today such as this one, the spacecraft ended up burning up over the Indian Ocean west of Indonesia at 2:24 am (Eastern) on May 10, 2025. It remains unclear whether it can be salvaged in any way.
————————-

The Aerospace Corporation’s prediction for the final uncontrolled re-entry of the Soviet Union’s 1972 failed Venus lander Venera has now been reduced to four hours, centered above the Indian Ocean near Indonesia, as shown on the map to the right, at around 1:29 pm Eastern.

This prediction however has great uncertainty, and will change in the next few hours. However, based on the orbits depicted, there is a good chance the lander will come down over either Europe or Asia.

As it was designed to survive the very thick and very hot atmosphere of Venus, there is also a good chance it will survive its uncontrolled re-entry through Earth’s atmosphere. Since Russia inherited all the assets of the Soviet Union, it will be responsible for any damage the lander does, as per the Outer Space Treaty.

SpaceX completes two launches today

11:36 pm

SpaceX successfully completed two Starlink launches today.

First, it placed 26 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its fourteenth flight, landing on a drone ship in the Pacific.

Next, it launched another 28 Starlink satellites from Cape Canaveral in Florida. The Falcon 9 first stage completed its eleventh flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

55 SpaceX
23 China
5 Rocket Lab
5 Russia

SpaceX now leads the rest of the world in successful launches, 55 to 40.

Academics in space community scheme to continue their racist DEI policies

1:41 pm

USRA logo

A letter sent out yesterday by the Universities Space Research Association (USRA) clearly illustrated the bigoted desire of our modern Marxist academic community to continue its racist Diversity, Equity, and Inclusion (DEI) policies in hiring by hiding or renaming them so that the Trump administration might not notice.

USRA is one of several university consortiums that manage a variety of space, science, and astronomical operations for the government. In USRA’s case, it manages the Lunar Planetary Institute (LPI) for NASA.

The letter purported to announce how the organization was complying with Trump’s executive orders banning such race-based programs, but instead revealed its desire to continue them, but to do so under the table where no one could monitor them.

China hints that it is moving forward with expansion of Tiangong-3 space station

12:39 pm

According to a statement by one Chinese official, China will use its Long March 5B rocket to soon launch more modules to its Tiangong-3 space station, expanding the station’s size considerably.

“According to the plan, the Long March 5B rocket will also carry out the future launches of additional modules for the crewed space station,” Wang Jue from China Aerospace Science and Technology Corporation (CASC) told China Central Television (CCTV) April 30. No official timeline has been released for the missions, but the comments appear to confirm plans to add modules to Tiangong, a T-shaped, three-module orbital outpost constructed across 2021-2022.

In 2022 China had hinted on this same plan, but it is three years later and nothing has yet happened. It could be this statement was an attempt at lobbying by this official, trying to convince the government to finance the new modules. Or it could be the first new module, a hub with six docking ports that will allow the additional fullsize modules to be attached, is nearing completion and launch.

Who knows? One must take all such proclamations from China with a grain of salt.

The article also notes the revisions to the Long March 5B rocket so that its core stage no longer reaches orbit to subsequently crash uncontrolled somewhere on Earth. Instead, the upper stage has been upgraded so that it gets the payload into orbit and the core stage shuts down earlier and thus falls into the ocean immediately after launch.

Rocket Lab’s as-yet unlaunched new Neutron rocket gets military contract

10:01 am

Capitalism in space: Rocket Lab has won a contract from the Air Force to test the use of its new Neutron rocket for tranporting cargo quickly across the globe, despite the fact that the rocket won’t make its first launch until later this year, at the earliest.

The mission, slated for no earlier than 2026, will fall under the Air Force Research Laboratory’s (AFRL) “rocket cargo” program, which explores how commercial launch vehicles might one day deliver materiel to any point on Earth within hours—a vision akin to airlift logistics via spaceflight.

…The cargo test would be a “survivability experiment.” Neutron is expected to carry a payload that will re-enter Earth’s atmosphere, demonstrating the rocket’s ability to safely transport and deploy cargo.

Neutron is designed to bring its first stage back to a vertical landing on Earth for re-use, similar to what SpaceX does with its Falcon 9. Unlike the Falcon 9, however, Neutron’s fairings remain attached to the rocket, opening and closing like alligator jaws to deploy its satellite payloads. Since it brings the fairing back attached to the rocket and closed after satellite deployment, the plan will be to see if it can carry within this enclosed fairing this Air Force test payload and bring it back unscathed.

This contract suggests the military is very confident that Neutron will fly as planned, and will succeed in its early launches.

Crash prediction for Soviet-era Venus probe narrows

9:36 am

May 9, 2025 morning prediction
Click for original image.

The prediction for when and where a 1972 Soviet-era failed Venus lander will crash back on Earth has now narrowed to an eight hour period on May 10, 2025, centered at 1:54 pm (Eastern).

The map to the right, from the Aerospace Corporation, shows the orbital path of the lander for the Venera lander, covering its last six orbits. Though the center of the prediction would have the lander come down over the Atlantic, that orbit has it crossing parts of South America, all of Europe, much of Asia and India, and Australia.

The lander failed to leave Earth orbit when it was launched in 1972, and has been circling the Earth since. As it was designed to survive the very thick and hot atmosphere of Venus, it is likely to survive re-entry through Earth’s more benign atmosphere.

This prediction will narrow continuously for the rest of the day. I will post an update this evening.

This is late because I was stuck in a doctor’s office for an extra two hours because the idiots misplaced my file. (Ain’t it great how Obamacare digitized all medical records so they would never get lost?)
