Before the end of this decade, NASA plans to return astronauts to the Moon for the first time since the Apollo Era. But this time, through the Artemis Program, it won’t be a “footprints and flags” affair. With other space agencies and commercial partners, the long-term aim is to create the infrastructure that will allow for a “sustained program of lunar exploration and development.” If all goes according to plan, multiple space agencies will have established bases around the South Pole-Aitken Basin, which will pave the way for lunar industries and tourism.

For humans to live, work, and conduct various activities on the Moon, strategies are needed to deal with all the hazards – not the least of which is lunar regolith (or “moondust”). As the Apollo astronauts learned, moondust is jagged, sticks to everything, and can cause significant wear on astronaut suits, equipment, vehicles, and health. In a new study by a team of Texas A&M engineers, the regolith motion was found to be significantly altered due to inter-particle collisions. Given the many spacecraft and landers that will be delivering crews and cargo to the Moon in the near future, this is one hazard that merits close attention!

Intuitive Machines says it’s putting its Odysseus moon lander to bed for a long lunar night, with hopes of reviving it once the sun rises again near the moon’s south pole.

The Houston-based company and NASA recapped Odysseus’s six days of operation on the lunar surface, shared pictures showing its off-kilter configuration, and looked ahead to the mission’s next phase during a briefing today at Johnson Space Center in Texas.

The original plan called for the solar-powered spacecraft to be turned off when the sun fell below the lunar horizon, but Intuitive Machines CEO Steve Altemus said mission controllers would instead put the Odysseus into hibernation and try restoring contact in three weeks’ time. “We are going to leave the computers and the power system in a place where we can wake it up and do this development test objective, to actually try to ping it with an antenna and see if we can’t wake it up once it gets power again,” he told reporters.

Electrodes in Spacesuits Could Protect Astronauts from Harmful Dust on Mars

To quote NASA associate administrator Jim Reuter, sending crewed missions to Mars by 2040 is an “audacious goal.” The challenges include the distance involved, which can take up to six months to traverse using conventional propulsion methods. Then there’s the hazard posed by radiation, which includes increased exposure to solar particles, flares, and galactic cosmic rays (GCRs). And then there’s the time the crews will spend in microgravity during transits, which can take a serious toll on human health, physiology, and psychology.

But what about the challenges of living and working on Mars for several months at a time? While elevated radiation and lower gravity are a concern, so is Martian regolith. Like lunar regolith, dust on Mars will adhere to astronauts’ spacesuits and inflict wear on their equipment. However, it also contains harmful particles that must be removed to prevent contaminating habitats. In a recent study, a team of aerospace engineers tested a new electrostatic system for removing Martian regolith from spacesuits that could potentially remove harmful dust with up to 98% efficiency.

Odysseus Moon Lander Sends More Pictures — and We Know Where It Is

Four days after Intuitive Machines’ Odysseus lander made an off-kilter touchdown on the moon, the mission team is releasing snapshots that were taken during its descent.

The ultra-wide-angle images confirm that the lander is continuing to communicate with flight controllers, even though it’s lying in an awkward angle that limits how much data its antennas can transmit.

Meanwhile, images from NASA’s Lunar Reconnaissance Orbiter have identified Odysseus’ landing spot, within a mile (1.5 kilometers) of its intended target near a crater called Malapert A in the moon’s south polar region. The bad news is that the solar-powered lander may have to go dark sooner than anticipated.

Surprise! Japan’s SLIM Moon Lander Wakes Up After a Freezing Night

Japan’s space agency didn’t expect its wrong-side-up SLIM moon lander to revive itself after powering down for a circuit-chilling lunar night on Feb. 1. But that’s exactly what happened.

“Last night, a command was sent to SLIM and a response received, confirming that the spacecraft has made it through the lunar night and maintained communication capabilities!” the SLIM mission team reported today in a posting to X / Twitter.

Odysseus Moon Lander Is Tipped Over But Still Sending Data

The bad news is that Intuitive Machines’ Odysseus lander is tipped on its side after getting tripped up during its touchdown near the south pole of the moon. The good news? The plucky robotic spacecraft is nevertheless able to send back data.

Mission managers at the Houston-based company and at NASA, which is paying $118 million to support Odysseus’ space odyssey, are working on ways to maximize the scientific payback over the next nine or 10 days. “The vehicle is stable, near or at our intended landing site,” Intuitive Machines CEO Steve Altemus said today during a post-landing briefing at NASA’s Johnson Space Center. “We do have communications with the lander … so that’s phenomenal to begin with.”

Just by surviving the descent a day earlier, Odysseus made it into the history books as the first commercial lander to arrive safely on the moon — and the first U.S.-built spacecraft to do so since the Apollo 17 mission in 1972.

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.

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.

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.

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.
