SpaceX launches twice last night, with one launch using first stage for record 28th time

8:41 am

SpaceX last night successfully placed more than fifty Starlink satellites into orbit, launching Falcon 9 rockets from opposite coasts with one using first stage for record 28th time.

First the company placed 26 Starlink satellites into orbit from Vandenberg Space Force Base in California, the first stage completing its sixth flight by landing softly on a drone ship in the Pacific.

Four hours later the company placed 28 Starlink satellites into orbit from the Kennedy Space Center in Florida, the first stage completing its 28th flight by landing safely on a drone ship in the Atlantic. Not only did this set a new record for reflights by a Falcon 9 first stage, it matched the number of flights of the space shuttle Columbia (the last of which ended in its destruction). Columbia took 22 years to complete those flights. This booster took less than four years to do the same. And it is still viable and has the chance (along with several other Falcon 9 first stages) of eventually beating the flight records of the shuttles Discover (39 flights) and Atlantis (33).

The leaders in the 2025 launch race:

57 SpaceX
24 China
5 Rocket Lab
5 Russia

SpaceX now leads the rest of the world in successful launches, 57 to 41.

Poland completes suborbital test launch

8:36 am

A consortium of Polish private and public institutions announced on May 9, 2025 that it had successfully completed a suborbital rocket launch on April 15, 2025, testing the first stage of a planned three-stage suborbital rocket.

According to a separate release from ZPS Gamrat [one of the consortium partners], the rocket exceeded an altitude of 10 kilometres before being destroyed by its onboard flight termination system, as planned. The goal of the test was to validate the rocket’s navigation and control systems, engine performance under flight conditions, flight termination system, telemetry systems, and aerodynamic characteristics. According to the WITU release, teams are currently analysing the data collected during the flight.

The next flight will add the second stage, and is targeting a launch this summer. If successful, the third launch using all three stages will take place before the end of the year.

This solid-fueled rocket is essentially a re-invention of the Scout suborbital rockets that NASA (and its predecessor the N.A.C.A) tested and flew many times out of Wallops Island in the 1950s and 1960s. Those test flights tested many basic components used in orbital rockets today, while also doing short suborbital science research each flight. It appears Poland aims to do the same thing now.

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.
