SpaceX’s manned Freedom capsule has undocked with ISS with its crew of four

12:39 am

SpaceX’s manned Freedom capsule tonight undocked with ISS, carrying with it the two astronauts that launched with it in September as well as the two astronauts that launched on Boeing’s Starliner capsule in June.

At 1:05 a.m. EDT Tuesday, NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore, along with Roscosmos cosmonaut Aleksandr Gorbunov undocked from the space-facing port of International Space Station’s Harmony module aboard the SpaceX Dragon spacecraft.

Splashdown is scheduled for 5:57 pm (Eastern) March 18, 2025 off the coast of Florida. I have embedded the NASA live stream below.

Normally the transfer of control of the station from the old crew to the new one takes about a week. In this case NASA cut that transfer time to only three days because of the political desire to get the Starliner astronauts home more quickly. The irony is that NASA decided to leave them up there for almost seven months more than planned in order to disturb its normal ISS launch and crew schedule as little as possible. This effort now to shorten their spaceflight by a few measly days seems quite trivial in comparison.

The next time someone tells you Mars lacks water, show them this picture

1:09 pm

Lots of near surface ice on Mars
Click for original image.

In the past decade orbital images from Mars have shown unequivocally that the Red Planet is not the dry desert imagined by sci-fi writers for many decades prior to the space age. Nor is it the dry desert that planetary scientists had first concluded based on the first few decades of planetary missions there.

No, what the orbiters Mars Reconnaissance Orbiter (MRO) and Mars Express have clearly shown is that, except for the planet’s equatorial regions below 30 degrees latitude, the Martian surface is almost entirely covered by water ice, though it is almost always buried by a thin layer of protective dust and debris. Getting to that ice will be somewhat trivial, however, as it is almost always near the surface.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, is a perfect example. It was taken on January 31, 2025 by the high resolution camera on MRO. At the top it shows part of a small glacial-filled crater surrounded by blobby ground clearly impregnated with ice. That crater in turn sits on the rim of a much larger very-eroded ancient 53-mile-wide crater whose floor, also filled with glacial debris, can be seen at the bottom of this picture. The wavy ridge line at the base of the rim appears to be a moraine formed by the ebb and flow of the glacial ice that fills this larger crater.

None of these glacial features is particularly unique on Mars. I have been documenting their presence now at Behind the Black for more than six years. Yet, I find still that most news organizations — including many in the space community — remain utterly unaware of these revelations. Any new NASA or university press release that mentions the near-surface ice that covers about two-thirds of the planet’s surface results in news stories claiming “Water has been found on Mars!”, as if this is a shocking new fact from a place where little water is found.

It is very shameful that so many reporters and news organizations are so far out of touch with the actual state of the research on Mars.

Webb captures infrared images of five exoplanets orbiting two different stars

10:17 am

Four gas giants in infrared
Click for original image.

Using the Webb Space Telescope, astronomers have taken two different direct false-color infrared images of exoplanets orbiting the stars HR 8799 (130 light years away) and 51 Eridani (97 light years away.

The image of the four gas giants orbiting HR 8799 is to the right, cropped, reduced, and slightly enhanced to post here. From the caption:

The closest planet to the star, HR 8799 e, orbits 1.5 billion miles from its star, which in our solar system would be located between the orbit of Saturn and Neptune. The furthest, HR 8799 b, orbits around 6.3 billion miles from the star, more than twice Neptune’s orbital distance. Colors are applied to filters from Webb’s NIRCam (Near-Infrared Camera), revealing their intrinsic differences. A star symbol marks the location of the host star HR 8799, whose light has been blocked by the coronagraph. In this image, the color blue is assigned to 4.1 micron light, green to 4.3 micron light, and red to the 4.6 micron light.

The Webb false color infrared picture taken of one of the exoplanets orbiting the star 51 Eridani is also at the link, showing “a cool, young exoplanet that orbits 890 million miles from its star, similar to Saturn’s orbit in our solar system.”

The data from the HR 8799 image suggests these gas giants have a lot of carbon dioxide gas, and thus might be growing by pulling in material from the star’s accretion disk.

Avio to begin testing its own Grasshopper prototype later this year

10:01 am

According to recent changes to its proposed plans, it appears that the Italian rocket company Avio hopes to begin tests of its own Grasshopper prototype vertical takeoff-and-landing stage later this year, with the hope of incorporating a reusable first stage in its upgraded Vega-Next rocket.

In the latest rendering shared in Avio’s 2024 full-year financial results presentation, control surfaces resembling those on a Falcon 9 booster are visible, seemingly confirming that the stage will be used to explore reusability.

In addition to the new rendering, Avio’s 2024 full-year financial results presentation included an update on the progress of the IFD1 mission. According to the company, integration of the demonstrator is ongoing, with an initial “firing test” expected in the third quarter of 2025. This test will likely be the final major milestone before the demonstrator is launched.

The company is targeting a 2032 first orbital launch of Vega-Next. Right now Avio owns the Vega-C rocket, and is the only private rocket company in Europe launching its own rocket. The only other operational European rocket, the larger Ariane-6, is operated by the European Space Agency. Another half-dozen-plus new private rockets are under development by other European rocket startups, but non have so far launched.

Norway awards the German rocket startup Isar Aerospace a two-satellite contract

9:48 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

In what appears to be a concerted effort by Norway to cement the establishment of its Andoya spaceport on its northwest coast, last week it awarded a two-satellite launch contract to the German rocket startup Isar Aerospace, launching from that spaceport.

The launch is scheduled until 2028 and will take place from Andøya Spaceport, Europe’s first operational spaceport on the mainland. The agreement between the Norwegian Space Agency and Isar Aerospace involves launching two Norwegian satellites as part of the AOS program, a national maritime surveillance system.

Isar is now gearing up for the very first orbital test launch of its Spectrum rocket, which will also be the very first from Andoya, and the very first from the four proposed spaceports in Europe. Regulatory filings from Norway suggest it will occur during a ten-day launch window beginning on March 20, 2025, but Isar has not yet confirmed this.

Unlike the two UK spaceports, which have been delayed years due to government red tape, Norway’s government has apparently worked hard to cut red tape and help Isar get off the ground quickly. It also appears that Norway’s government is acting to stymie Sweden’s Esrange spaceport, releasing a report last week that suggested it will not give permission for launches over its territory from Esrange.

Varda’s third capsule begins orbital operations

9:37 am

Varda's space capsule, on the ground in Utah
Varda’s first capsule on the ground in Utah.

The in-space commercial company Varda on March 15, 2025 confirmed that its third capsule has successfully begun orbital operations after its launch on a Falcon 9 rocket, carrying an Air Force payload that will test measuring the capsule’s re-entry speeds in connection with military hypersonic research.

W-3’s payload is an advanced navigation system called an Inertial Measurement Unit (IMU) developed by the US Air Force and Innovative Scientific Solutions Incorporated (ISSI). This payload will be tested at reentry speeds it was designed to withstand but has never encountered before.

This payload is part of a $48 million Air Force contract awarded to Varda in December. The company also notes in the press release that it is aiming for a monthly launch rate for its capsules, which provide customers an opportunity to do all kinds of in-space testing and manufacturing. Since this launch took place only fifteen days after the landing of its second capsule, it appears Varda is moving swiftly in that direction, thus providing more business for American rocket startups.

The capsule includes a service module built by Rocket Lab, and will stay in orbit several weeks before it returns to Earth, landing at the Koonibba Test Range in South Australia, operated by the Australian commercial spaceport startup Southern Launch.

Firefly’s Blue Ghost ends its mission, having achieved all its mission goals

9:23 am

Blue Ghost's shadow on the Moon, with the Earth in the background
Blue Ghost’s shadow on the Moon shortly
after landing, with the Earth in the background.

Five hours after lunar sunset Firefly yesterday shut down its Blue Ghost lander, ending its mission after successfully completing all its assigned tasks in carrying ten NASA research payloads to the Moon and softly placing them on the lunar surface.

Firefly also captured imagery of the lunar sunset on March 16, providing NASA with data on whether lunar dust levitates due to solar influences and creates a lunar horizon glow that was hypothesized and observed by Eugene Cernan on Apollo 17. Following the sunset, Blue Ghost operated for 5 hours into the lunar night and continued to capture imagery that measures how dust behavior changes after sunset.

“Whether lunar dust levitates” is one of the biggest scientific mysteries about the Moon. Only one person, astronaut Harrison Schmidt, has observed the phenomenon during the last Apollo mission to the Moon, and numerous attempts since to confirm and better understand it have all failed for one reason or the other. The preliminary results of Blue Ghost observations will be announced at a press conference tomorrow.

Firefly is now gearing up for annual Blue Ghost lunar missions. The next is targeting a launch next year, and will also deliver payloads for NASA, the European Space Agency, and Australia.

Chinese pseudo-company launches 8 satellites

9:09 am

The Chinese pseudo-company Galactic Energy today successfully placed eight remote-sensing satellites into orbit, its solid-fueled Ceres-1 rocket lifting off from the Jiuquan spaceport in northwest China.

No word on where the rocket’s lower stages crashed inside China.

This was Ceres-1’s eighteenth launch, making Galactic Energy the most successful rocket pseudo-company so far in China. That its rocket uses solid-fueled shows us however that it is strongly tied to China’s military, and likely controlled tightly by it.

The leaders in the 2025 launch race:

31 SpaceX
13 China
4 Russia
3 Rocket Lab

SpaceX still leads the rest of the world in successfully launches, 31 to 23.
