This week’s image is from the James Webb Space Telescope (JWST). It shows a face-on view of spiral galaxy NGC 1300, which is 69 million light-years away.

Here is more about the image from NASA:

Webb’s image of NGC 1300 shows a face-on barred spiral galaxy anchored by its central region, which is circular and shows a bright white point at the center with a light yellow circle around it. The central core is tiny compared to the rest of the galaxy. The core extends into the galaxy’s prominent diagonal bar structure, which is filled with a blue haze of stars. Orange dust filaments cross the bar, extending diagonally to the top and bottom, connecting the yellow circle in the central core to the galaxy’s spiral arms. There are two distinct orange spiral arms made of stars, gas, and dust that start at the edges of the bar and rotate counterclockwise. Together, the arm and bars form a backward S shape. The spiral arms are largely orange, ranging from dark to bright orange. Scattered across the packed scene are very few bright blue pinpoints of light. There are vast areas between where the orange spiral arms wrap that appear black. The top left and bottom right edges are dark black and there are some larger red and blue points of light, some that appear like disks seen from the side.

Another Crew Departing for the ISS

Later today, a SpaceX rocket with carry another crew to the International Space Station (ISS) after a few delays. The crew, shown above, consists of Alexander Grebenkin (Roscosmos), Michael Barratt (NASA), Matthew Dominick (NASA), Jeanette Epps (NASA).

The new crew will be approaching a space station already containing seven crew members as well as a module in need of repair. The Russian components of the space station have sprung a number of leaks over the past several years. The most recent appears to be a recurring oxygen leak.

To date, NASA is playing it cool, though I expect everyone on board would be happy to experience at leakless station as soon as possible. We know the ISS will not last forever, but until the day it is decommissioned it should be a safe vessel for the astronauts and cosmonauts aboard.

Update: The SpaceX launch went off without a hitch Sunday evening. The new crew on the Dragon spacecraft is expected to reach the ISS Tuesday morning.

Space Quote: The End of NASA’s OSAM-1 Project

“Following an in-depth, independent project review, NASA has decided to discontinue the On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1) project due to continued technical, cost, and schedule challenges, and a broader community evolution away from refueling unprepared spacecraft, which has led to a lack of a committed partner. Following Congressional notification processes, project management plans to complete an orderly shutdown, including the disposition of sensitive hardware, pursuing potential partnerships or alternative hardware uses, and licensing of applicable technological developments. NASA leadership also is reviewing how to mitigate the impact of the cancellation on the workforce at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.”

-Statement by NASA in recent communications. The project has been in development since 2015. About 450 NASA employees and contractors working on the OSAM-1 project. In an earlier report by the Government Accountability Office, the auditors noted, “OSAM-1 cost growth and schedule delays are exacerbated by poor contractor performance and continued technical challenges.”

Pic of the Week: A Rough Moon Landing

This week’s image shows the Odysseus lunar lander as it is about to touch the Moon’s surface. It tipped over upon landing.

Here is the statement about the image from Initiative Machines:

This image retrieved from the lander on February 27 captures Odysseus’ landing strut during landing on February 22nd performing its primary task, absorbing first contact with the lunar surface. Meanwhile, the lander’s liquid methane and liquid oxygen engine is still throttling, which provided stability. The Company believes the two insights captured in this image enabled Odysseus to gently lean into the lunar surface, preserving the ability to return scientific data.

NASA tried to put its best spin on the science coming out of the tilted lander, which suffered solar array and communication issues related to its tilted position, stating:

Mission challenges and successes were discussed during the briefing including more than 350 megabits of science data downloaded ready for analysis. During transit, all powered NASA payloads operated and received data. During descent and landing, guidance and navigation data was collected that will help improve landing precision in the future, and all three payloads that were designed to operate on the surface have received data.

What is left unsaid is whether the data received during this landing was close to what was anticipated and necessary for future safe missions. Saying some data was received does not tell us much. Only complete and useful data really matters here. I expect more information will be shared shortly.

I have not read too much about the fate of the other commercial cargoes. I doubt they fared much better.

Fortunately, the lunar lander communicated with Earth until early this morning, outlasting earlier expectations.

Could it come alive again like the Japanese lander? We shall see. As Intuitive Machines said earlier today, “Goodnight, Odie. We hope to hear from you again.”

Space Stories: DART Damage, India Plans for Orbiting Crew, and SLIM Awakes on the Moon

A recent study suggests NASA’s DART mission, designed to test asteroid deflection methods, may have revealed more than planned. While successfully altering the target asteroid’s trajectory, scientists now believe the impact also significantly changed its shape, hinting at a surprising composition. Previously thought to be a solid rock, Dimorphos, the impacted asteroid, may actually be a loose collection of debris. This conclusion stems from the unexpected level of deformation observed after the collision. Unlike a typical crater, the impact appears to have caused a broader, flatter dent, resembling an M&M candy.

India on Tuesday introduced four crew members for its maiden ‘Gaganyaan’ space voyage, as it aims to become the world’s fourth country to send a crewed mission into space just months after a historic landing on the south pole of the moon. Gaganyaan, or “sky craft” in Hindi, is the first mission of its kind for India and will cost about 90.23 billion rupees ($1.1 billion). It involves the launch of a habitable space capsule over the next year to an orbit of 400 km (250 miles) and its return via a landing in the Indian Ocean.

Japan’s space agency made contact with its SLIM moon lander Sunday, despite the spacecraft not being expected to function after lunar night. Contact with the Smart Lander for Investigating Moon (SLIM) spacecraft was reestablished on Sunday, Feb. 25, the Japan Aerospace Exploration Agency (JAXA) announced via its dedicated SLIM account on X, formerly known as Twitter, early Feb. 26.
