Lockheed Martin invests in new solid-fueled rocket startup

9:36 am

In its most recent fund-raising round, the solid-fueled rocket startup X-Bow (pronounced “crossbow”) raised $35 million in private investment capital, with Lockheed Martin being the largest investor.

Lockheed Martin’s involvement marks a deepening interest in securing alternative sources for solid rocket motors, components that are increasingly vital to a wide range of U.S. missile systems, including hypersonic weapons. The investment comes three years after Lockheed’s attempt to acquire Aerojet Rocketdyne was blocked by the Federal Trade Commission on antitrust grounds. Aerojet was later bought by L3Harris Technologies, leaving Lockheed without a vertically integrated propulsion supplier.

Nor is this the first time that Lockheed Martin has invested in a rocket startup. It had previously invested in ABL and Orbex, both liquid-fueled but struggling or failing, as well as the much more successful Rocket Lab. It has also invested in the orbital tug startup Orbit Fab, the orbital capsule company Inversion Space, and the satellite startup Terran Orbital, which it ended up buying entirely.

All in all, Lockheed Martin appears determined to join the new wave of space startups, if not by doing it itself but by buying into the successes of new startups. So far this has not entirely paid off, but it does appear to be, in the long term, a viable strategy to keep Lockheed Martin competitive and in the game.

NASA engineers end second super pressure balloon flight early

Flight path of second super pressure balloon test
Flight path of second super pressure balloon test

Due to an issue with its power system, NASA engineers today decided to end its second super pressure balloon flight this year after only nine days, when the balloon crossed over South America and thus allowing them to recover it safely.

Although the balloon performed well and the mission successfully met its minimum requirements toward qualification of the balloon system, an issue with the power system aboard the balloon gondola prompted the team to terminate the mission early as a precaution. The team had been monitoring a power failure in one of the redundant charging systems since May 8.  “Despite the loss of one of the redundant charging systems, the remaining power system was performing very well and still able to sustain the batteries and electrical equipment over the course of the mission,” said Hamilton. “However, to be cautious, the team opted to end the flight early to get the equipment back, so we can do a full failure analysis.” 

After identifying a safe area and coordinating with Argentinian officials, the flight was safely terminated. Recovery of the balloon and payload is in progress. 

The first flight flew for seventeen days, circling the globe at the high southern latitudes. In that case issues with the balloon caused the flight to be terminated while it was over the ocean, preventing recovery. As the goal with both flights was to fly for 100 days, neither came close to that target.

NASA releases thermal image of Mars taken by Europa Clipper

9:11 am

Click for original image.

NASA yesterday released a thermal image of Mars taken by during Europa Clipper’s March 1, 2025 fly-by of the red planet on its way to Jupiter. From the caption:

This picture of Mars is a composite of several images captured by Europa Clipper’s thermal imager on March 1. Bright regions are relatively warm, with temperatures of about 32 degrees Fahrenheit (0 degrees Celsius). Darker areas are colder. The darkest region at the top is the northern polar cap and is about minus 190 F (minus 125 C).

The press release doesn’t identify the bullseye feature on the left. I think the bright area inside the bullseye might be the shield volcano Syrtis Major, with the dark area to the right Isidis Basin, which means this is also a snapshot of Perseverance, sitting on the basin’s western perimeter. The dark feature on the right edge of the image might be the giant volcano Elysium Mons. These however are total guesses and likely wrong.

The mission team used this fly-by to test the spacecraft’s science instruments, and have so far found all to be working as expected.

Europa Clipper will do one more fly-by of Earth in December 2026, allowing it to reach Jupiter in April 2030.

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.

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.

Bright material on the high points of a Martian mountain

12:29 pm

Bright material on top of a Martian mountain
Click for original image.

Today’s cool image is mostly an example of the present unknowns of Mars. The picture to the right, cropped, reduced, and sharpened to post here, was taken on April 2, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team quite rightly labels this vaguely as “bright materials,” referring to the bright rim of that crater as well as the scattered bright patches on the surrounding plain. This vagueness tells us that the scientists don’t have enough data yet to definitively identify this stuff, though they know it is distinctly unique because of its inexplicable bright albedo compared to everything around it.

That the crater rim (as well as all the crater rims in the full picture) exhibit this same brightness suggests this material was excavated from below when the impacts hit. The surrounding patches suggest that erosion has exposed this buried material at these points.
