Intuitive Machines’ Odysseus Lander Sends Faint Signal From the Moon

Intuitive Machines‘ Odysseus lander made space history today — becoming the first commercial spacecraft to survive a descent to the moon, and the first U.S.-built spacecraft to do so since the Apollo 17 mission in 1972. But it wasn’t a trouble-free landing.

Ground controllers had a hard time establishing contact with the robotic lander just after the scheduled touchdown time of 6:23 p.m. ET (2323 UTC). Several minutes passed, and then Intuitive Machines mission director Tim Crain reported that there was a faint signal coming from Odysseus’ high-gain antenna.

“We’re not dead yet,” he said.

Odysseus Moon Lander Sends Back Selfies With Earth in the Picture

Intuitive Machines’ Odysseus lander has beamed back a series of snapshots that were captured as it headed out from the Earth toward the moon, and one of the pictures features Australia front and center. The shots also show the second stage of the SpaceX Falcon 9 rocket that launched the spacecraft, floating away as Odysseus pushed onward.

Now it’s Intuitive Machines’ turn to try making history with a robotic moon landing.

Today’s launch of the Houston-based company’s Odysseus lander marks the first step in an eight-day journey that could lead to the first-ever soft landing of a commercial spacecraft on the moon. Odysseus would also be the first U.S.-built spacecraft to touch down safely on the lunar surface since Apollo 17’s mission in 1972.

The lander — which is as big as an old-fashioned British phone booth, or the Tardis time portal from the “Doctor Who” TV series — was sent spaceward from Launch Complex 39A at NASA’s Kennedy Space Center atop a SpaceX Falcon 9 rocket at 1:05 a.m. ET (0605 UTC).

Engineers Design Habitats for the Moon Inspired by Terminite Mounds

Through the Artemis Program, NASA intends to send astronauts back to the Moon for the first time since the Apollo Era. But this time, they intend to stay and establish a lunar base and other infrastructure by the end of the decade that will allow for a “sustained program of lunar exploration and development.” To accomplish this, NASA is enlisting the help of fellow space agencies, commercial partners, and academic institutions to create the necessary mission elements – these range from the launch systems, spacecraft, and human landing systems to the delivery of payloads.

With NASA funding, a team of engineers from the University of Arizona College of Engineering (UA-CE) is developing autonomous robot networks to build sandbag shelters for NASA astronauts on the Moon. The designs are inspired by cathedral termite mounds, which are native to Africa and northern Australia’s desert regions. Their work was the subject of a paper presented at the American Astronautical Society Guidance, Navigation, and Control (AAS GNC) Conference, which took place from February 1st to 7th in Littleton and Breckinridge, Colorado.

Chickpeas Grown in Lunar Regolith Are Stressed but Reach Maturity

A recent preprint investigates how chickpeas have been successfully grown in lunar regolith simulants (LRS), marking the first time such a guideline has been established not only for chickpeas, but also for growing food for long-term human space missions. This study was conducted by researchers from Texas A&M University and Brown University and holds the potential to develop more efficient methods in growing foods using extraterrestrial resources, specifically with NASA’s Artemis program slated to return humans to the lunar surface in the next few years.

NASA is One Step Closer to Deploying Fission Reactors on the Moon

What’s the most important thing you need to live and work on the Moon? Power. For NASA’s upcoming Artemis program, getting power to lunar bases is a top priority. That’s why the agency created its Fission Surface Power Project. The idea is to develop concepts for a small nuclear fission reactor to generate electricity on the lunar surface.

Japan Moon Lander Sleeps After Sending Science — Will It Wake Up Again?

After a few days of wakefulness, Japan’s SLIM moon lander has gone dormant once more at the start of a 14-day-long lunar night. The upended robot sent back a stream of data and imagery while its solar cells were in position to soak up sunlight, and its handlers hope they can get SLIM to wake up again and resume its work after lunar sunrise in mid-February.

NASA Wants to Put a Massive Telescope on the Moon

As part of the Artemis Program, NASA intends to establish all the necessary infrastructure to create a “sustained program of lunar exploration and development.” This includes the Lunar Gateway, an orbiting habitat that will enable regular trips to and from the surface, and the Artemis Base Camp, which will permit astronauts to remain there for up to two months. Multiple space agencies are also planning on creating facilities that will take advantage of the “quiet nature” of the lunar environment, which includes high-resolution telescopes.

As part of this year’s NASA Innovative Advance Concepts (NIAC) Program, a team from NASA’s Goddard Space Flight Center has proposed a design for a lunar Long-Baseline Optical Imaging Interferometer (LBI) for imaging at visible and ultraviolet wavelengths. Known as the Artemis-enabled Stellar Imager (AeSI), this proposed array of multiple telescopes was selected for Phase I development. With a little luck, the AeSI array could be operating on the far side of the Moon, taking detailed images of stellar surfaces and their environments.

The Moon is Still Shrinking, Explaining Why it Still Has Landslides

Although our Moon formed 4.5 billion years ago, it’s still evolving. The interior continues to cool and its orbit is slowly changing. As a result, the Moon has lost 150 feet of its circumference. That shrinkage contributes to near-constant moonquakes, and those trigger landslides and other surface changes. The Moon is currently uninhabited, but all that activity threatens future Artemis landing sites and missions at the South Pole.

Japan’s Moon Lander Is Lying On Its Side After Hitting Its Target

Now we know why Japan’s lunar lander wasn’t able to recharge its batteries after touching down on the moon last week: The spacecraft appears to have tumbled onto its side, with its solar cells facing away from the sun.

The good news is that the Smart Lander for Investigating Moon, or SLIM, achieved its primary mission of setting down within 100 meters (330 feet) of its target point — and that the mission’s two mini-probes, which were ejected during SLIM’s descent, are working as intended.

Scores of images were taken before and after landing. One of the pictures. captured by a camera on the ball-shaped LEV-2 mini-probe, shows the lander sitting at an odd angle with its thrusters facing upward and its solar cells facing westward.

To conserve battery power, mission managers at the Japan Aerospace Exploration Agency shut down SLIM after the probes transmitted the imagery they collected. But there’s still a chance that the sun’s shifting rays could provide enough power to allow for further operations in the week ahead.
