Some of the biggest names in aerospace — and the automotive industry — will play roles in putting NASA astronauts in the driver’s seat for roving around on the moon.

The space agency today selected three teams to develop the capabilities for a lunar terrain vehicle, or LTV, which astronauts could use during Artemis missions to the moon starting with Artemis 5. That mission is currently scheduled for 2029, three years after the projected date for Artemis’ first crewed lunar landing.

The teams’ leading companies may not yet be household names outside the space community: Intuitive Machines, Lunar Outpost and Venturi Astrolab. But each of those ventures has more established companies as their teammates.

On March 20th, China’s Queqiao-2 (“Magpie Bridge-2”) satellite launched from the Wenchang Space Launch Site LC-2 on the island of Hainan (in southern China) atop a Long March-8 Y3 carrier rocket. This mission is the second in a series of communications relay and radio astronomy satellites designed to support the fourth phase of the Chinese Lunar Exploration Program (Chang’e). On March 24th, after 119 hours in transit, the satellite reached the Moon and began a perilune braking maneuver at a distance of 440 km (~270 mi) from the lunar surface.

The maneuver lasted 19 minutes, after which the satellite entered lunar orbit, where it will soon relay communications from missions on the far side of the Moon around the South Pole region. This includes the Chang’e-4 lander and rover and will extend to the Chang’e-6 sample-return mission, which is scheduled to launch in May. It will also assist Chang’e-7 and -8 (scheduled for 2026 and 2028, respectively), consisting of an orbiter, rover, and lander mission, and a platform that will test technologies necessary for the construction of the International Lunar Research Station (ILRS).

On February 15th, Intuitive Machines (IM) launched its first Nova-C class spacecraft from Kennedy Space Center in Florida atop a SpaceX Falcon 9 rocket. On February 22nd, the spacecraft – codenamed Odysseus (or “Odie”) – became the first American-built vehicle to soft-land on the lunar surface since the Apollo 17 mission in 1972. While the landing was a bit bumpy (Odysseus fell on its side), the IM-1 mission successfully demonstrated technologies and systems that will assist NASA in establishing a “sustained program of lunar exploration and development.”

After seven days of operation on the lunar surface, Intuitive Machines announced on February 29th that the mission had ended with the onset of lunar night. While the lander was not intended to remain operational during the lunar night, flight controllers at Houston set Odysseus into a configuration that would “call home” if it made it through the two weeks of darkness. As of March 23rd, the company announced that their flight controllers’ predictions were correct and that Odie would not be making any more calls home.

Roughly two years and six months from now, as part of NASA’s Artemis III mission, astronauts will set foot on the lunar surface for the first time in over fifty years. Beyond this mission, NASA will deploy the elements of the Lunar Gateway, the Artemis Base Camp, and other infrastructure that will allow for a “sustained program of lunar exploration and development.” They will be joined by the European Space Agency (ESA), the China National Space Agency (CNSA), and Roscosmos, the latter two collaborating to build the International Lunar Research Station (ILRS).

Anticipating this process of lunar development (and looking to facilitate it), the Defense Advanced Research Projects Agency (DARPA) launched the 10-year Lunar Architecture (LunA-10) Capability Study in August last year. In recent news, the agency announced that it selected Northrop Grumman to develop a moon-based railroad network. This envisioned network could transport humans, supplies, and resources for space agencies and commercial ventures, facilitating exploration, scientific research, and the creation of a lunar economy.

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!

NASA Tests the New Starship Docking System

SpaceX and NASA recently performed full-scale qualification testing of the docking system that will connect SpaceX’s Starship Human Landing System (HLS) with Orion and later Gateway in lunar orbit during future crewed Artemis missions. Based on the flight-proven Dragon 2 active docking system, the Starship HLS docking system will be able to act as an active or passive system during docking. Image Credit: SpaceX

The Apollo Program delivered 12 American astronauts to the surface of the Moon. But that program ended in 1972, and since then, no human beings have visited. But Artemis will change that. And instead of just visiting the Moon, Artemis’ aim is to establish a longer-term presence on the Moon. That requires more complexity than Apollo did. Astronauts will need to transfer between vehicles.

All of that activity requires a reliable spacecraft docking system.

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.

As NASA continues to ramp up efforts for its Artemis program, which has the goal of landing the first woman and person of color on the lunar surface, two NASA astronauts recently conducted training with a replica of SpaceX’s Starship human landing system (HLS), albeit on a much smaller scale. Given that Starship is 50 meters (160 feet) tall, and the crew quarters are located near the top of Starship, the HLS will need an elevator with a basket to transport crew and supplies from the crew quarters down to the surface. The purpose of this training is to familiarize astronauts with all aspects of this system, including elevator and gate controls and latches, along with how the astronauts perform these tasks in their bulky astronaut suits, which both astronauts wore during the training.

For almost half a century, the term “Anthropocene” has been informally used to describe the current geological epoch. The term acknowledges how human agency has become the most significant factor when it comes to changes in Earth’s geology, landscape, ecosystems, and climate. According to a new study by a team of geologists and anthropologists, this same term should be extended to the Moon in recognition of humanity’s exploration (starting in the mid-20th century) and the growing impact our activities will have on the Moon’s geology and the landscape in the near future.

With NASA gearing up to send humans back to the Moon in the next few years with the Artemis missions with the goal of establishing a permanent outpost at the lunar south pole, nations are making efforts to contribute to Artemis and a permanent presence on our nearest celestial neighbor. Recently, the Italian Space Agency, formally known as Agenzia Spaziale Italiana (ASI), has taken steps to establish the first permanent outpost on the lunar surface, known simply as the Multi-Purpose Habitat (MPH). This endeavor was officially kicked by the ASI signing a contract with the French-based aerospace company, Thales Alenia Space, who specializes in space-based systems, including ground segments and satellites used for both Earth observation and space exploration.
