In Case You Missed It/Video: The Stakes Are High with Our Return to the Moon

With the recent glitches related to the two commercial Moon missions, an earlier NASA video on the Artemis program became all too relevant. In the video, “Farther and Faster: NASA’s Journey to the Moon with Artemis,” we hear that the stakes are high as we attempt to return to the Moon, and how we could be the generation that loses the Moon if we don’t get it right.

In addition to the risks, the video also highlights the great successes already with the Artemis I mission, as you may recall from back in 2022:

Over the course of 25.5 days, Orion performed two lunar flybys, coming within 80 miles (129 kilometers) of the lunar surface. At its farthest distance during the mission, Orion traveled nearly 270,000 miles (435,000 kilometers) from our home planet. On Dec. 11, 2022, NASA’s Orion spacecraft successfully completed a parachute-assisted splashdown in the Pacific Ocean at 9:40 a.m. PST (12:40 p.m. EST) as the final major milestone of the Artemis I mission.

Artemis I set new performance records, exceeded efficiency expectations, and established new safety baselines for humans in deep space. This is a prelude to what comes next—following the success of Artemis I, human beings will fly around the Moon on Artemis II.

It is worth pondering what we have ahead of us. NASA may be having a few issues with its commercial partners, but the main mission has done well. We cannot be discouraged with a few delays as long as we keep the course. We have done it before and there is no reason we cannot do it again. I say slow and steady.

Mars is the goal, but we need to prove ourselves with the Moon. Check out the video and determine for yourself if we have already made a fair amount of progress.

Pic of the Week: Spiral galaxy NGC 1300

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.”
