A SpaceX Dragon freighter, on its third flight, today successfully docked with ISS, bringing with it several tons of supplies and several medical and engineering experiments.
It will remain at the station for about a month, during which astronauts will unload its supplies and experiments and load it with cargo and research results for safe return to Earth.
Virgin Orbit today paused all operations for at least a week, putting almost its entire staff on furlough as it seeks new financing.
Chief Executive Dan Hart told staff that the furlough would buy Virgin Orbit time to finalise a new investment plan, a source who attended the event told Reuters news agency. It was not clear how long the furlough would last, but Mr Hart said employees would be given more information by the middle of next week.
If Virgin Orbit dies, its death will be because a British government agency killed it. The company had planned on launching from Cornwall in the early fall of 2022, at the latest, and then do several other launches in 2022, all of which would have earned it revenue. Instead, the UK’s Civil Aviation Authority (CAA) delayed issuing the launch license until January 2023, about a half a year later, preventing Virgin Orbit from launching for that time and literally cutting it off from any ability to make money. The result was that it ran out of funds.
Obviously the launch failure that followed the CAA’s approval did not help. Nor did the company’s decision to rely on only one 747 to launch its satellites. Nonetheless, the fault of this company’s death can mostly be attributed to a government bureaucracy that failed in its job so badly that it destroyed a private company.
China yesterday used its Long March 11 solid-fueled four-stage rocket to launch a classified Earth observation satellite into orbit.
The launch was from an interior spaceport, so the rocket’s lower stages crashed somewhere in China or Mongolia. No word on if they landed near habitable areas.
The 2023 launch race:
17 SpaceX
10 China
4 Russia
1 Rocket Lab
1 Japan
1 India
American private enterprise still leads China 18 to 10 in the national rankings, and the entire world combined 18 to 16. SpaceX alone is now tied with entire world, including the rest of the U.S., 17 to 17.
Scientists have uncovered geological evidence of a past glacier in westernmost end of the giant Martian canyon Valles Marineris, right at the point where it transitions into the complex chaos region dubbed Noctis Labyrinthus. The white dot on the map to the right indicates the location.
The surface feature identified as a “relict glacier” is one of many light-toned deposits (LTDs) found in the region. Typically, LTDs consist mainly of light-colored sulfate salts, but this deposit also shows many of the features of a glacier, including crevasse fields and moraine bands. The glacier is estimated to be 6 kilometers long and up to 4 kilometers wide, with a surface elevation ranging from +1.3 to +1.7 kilometers. This discovery suggests that Mars’ recent history may have been more watery than previously thought, which could have implications for understanding the planet’s habitability.
“What we’ve found is not ice, but a salt deposit with the detailed morphologic features of a glacier. What we think happened here is that salt formed on top of a glacier while preserving the shape of the ice below, down to details like crevasse fields and moraine bands,” said Dr. Pascal Lee, a planetary scientist with the SETI Institute and the Mars Institute, and the lead author of the study. [emphasis mine]
You can read the paper here [pdf]. The research specifically suggests that near surface water ice in the dry equatorial regions of Mars could have been there much more recently that previously believed. It also suggests, by the rarity of this discovery, that there is likely almost no near surface ice in the equatorial regions, at present.

During Ingenuity’s 47th flight on Mars on March 9, 2023, one of Perseverance’s high resolution camera’s took rapid-fire images of the helicopter’s take-off and initial flight, from which the science team created a movie.
The overview map to the right provides the context for that movie at the link. The blue dot marks Perserverance’s location, with the yellow lines indicating the approximate area seen in the movie. The smaller green dot and line indicates Ingenuity’s take-off point and part of its flight seen in the movie, with the larger green dot its landing spot. From the press release:
This video shows the dust initially kicked up by the helicopter’s spinning rotors, as well as Ingenuity taking off, hovering, and beginning its 1,444-foot (440-meter) journey to the southwest.
At take-off Ingenuity was 394 feet away from Perseverance.
Capitalism in space: Firefly announced today that it has won a $112 million NASA contract to use its Blue Ghost lunar lander to bring three instruments to the Moon, one into orbit and two on the ground on the far side of the Moon.
Before landing on the Moon, the company’s Blue Ghost transfer vehicle will deploy the European Space Agency’s Lunar Pathfinder satellite into lunar orbit to provide communications for future spacecraft, robots, and human explorers. After touching down on the far side of the Moon, the Blue Ghost lunar lander will deliver and operate NASA’s S-Band User Terminal, ensuring uninterrupted communications for lunar exploration, and a research-focused payload that measures radio emissions to provide insight into the origins of the universe.
The NASA press release provides more details about the three payloads.
This is Firefly’s second NASA lunar lander contract. The first is scheduled to land in 2024 and deliver ten NASA science instruments to Mare Crisium, the large mare region in the eastern side of the Moon’s visible hemisphere. This second flight is tentatively scheduled to launch in 2026.
NASA today announced that it has given Axiom the go-ahead for its third planned commercial passenger mission to ISS, now tentatively scheduled for November 2023.
Axiom Mission 3 (Ax-3) is expected to spend 14 days docked to the space station. A specific launch date is dependent on spacecraft traffic to the space station and in-orbit activity planning and constraints. NASA and Axiom Space mission planners will coordinate in-orbit activities for the private astronauts to conduct in coordination with space station crew members and flight controllers on the ground.
As NASA did in announcing its agreement to Axiom’s previous flight, the agency’s press release makes believe it “selected” Axiom for this flight, as if it had the power and right to do so. Hogwash. Axiom has purchased the flight from SpaceX, and wishes to rent space on ISS for two weeks for its customers. All NASA has done is agree to the deal, while also charging Axiom very large fees for that rental.
Capitalism in space: SpaceX tonight successfully used its Falcon 9 rocket to put a cargo Dragon capsule into orbit and on its way to ISS.
The first stage successfully completed its seventh flight, landing on a drone ship in the Atlantic. The Dragon freighter is making its third flight, and will dock with ISS on the morning of March 16th.
The 2023 launch race:

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on January 2, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It is once again a terrain sample image, taken not for any specific research but to fill a gap in the schedule so as to maintain the camera’s proper temperature.
What this picture shows is that even though Mars has a thin atmosphere that produces dust devils, the propagation of dust devils is not uniform across the red planet’s surface. In this picture there are a lot of devil tracks, going in many different directions. Yet few of the many cool images I post from MRO show this number of tracks. In many cases the ground might not be agreeable to leaving tracks, but that cannot be the entire explanation.

The panorama above was released today by the Lunar Reconnaissance Orbiter (LRO) science team, and shows one of the candidate landing sites (arrow) where Starship could land as part of the Artemis-3 mission to the Moon.
The map of the south pole to the right, created from LRO images and annotated by me, gives the context. The yellow lines indicate the approximate area covered by the panorama. The terrain here is rugged, to put it mildly. As the science team notes,
Imagine the view from the summit; it rises more than 5000 meters (16,400 feet) above its base. Off in the distance, you could see a 3500 meter (11,480 feet) tall cliff. One could argue that the sheer grandeur of this region makes it a prime candidate. But then again, a landing here might be too exciting?
That 11,480-foot-high cliff is the crater wall to the right of the arrow. Make sure you go to the link to view the original image. This will be a spectacular place to visit. Whether the astronauts however will be able to find out anything about ice in the shadowed crater floor thousands of feet below them remains questionable.
Artemis-3 is presently scheduled for 2025 but no one should be surprised if it is delayed.
LeoLabs, a private commercial company aiming to provide orbital tracking of all space objects as small as two centimeters, has announced plans to establish its seventh global radar facility in Argentina.
The S-band radar, scheduled to be completed by the end of the year, will be located on the archipelago of Tierra del Fuego. “The Southern Hemisphere has not been well covered for space safety and space domain awareness,” LeoLabs CEO Dan Ceperley told SpaceNews. “There are a lot of conjunctions close to the North Pole and the South Pole. This radar will make a very meaningful improvement in the tracking of those conjunctions.”
Currently, LeoLabs tracks objects in low-Earth orbit with phased array radars in Alaska, Australia, Portugal’s Azores archipelago, New Zealand, Texas and Costa Rica.
The company essentially competes with the Space Force in tracking object in orbit, and has raised more than $100 million in private investment capital to build its ground stations.

Cool image time! The picture to the right, cropped and sharpened to post here, was taken on February 3, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a number of crater splats of varying sizes. If you look at the full image, you will find several even bigger splats to the north of the one in the picture to the right. You will also see many more similar-sized crater splats to the south.
I cannot provide any confident explanation about what caused these splats, other than to assume that most here are secondary impacts from ejecta thrown out by a larger impact somewhere nearby. I also assume all these small impacts occurred at the same time because they all appear to have hit the ground when it had the same thick liquid consistency, a condition that was probably temporary. Note for example how many of the other craters in the full image do not have this same splattered look.
