If history has taught us one thing, it is that science fiction often gives way to science fact. Consider the Star Trek communicator and the rise of flip phones in the late 1990s and early 2000s, or how 2001: A Space Odyssey predicted orbiting space stations and reusable space planes – like the International Space Station (ISS) and the Space Shuttle. And who can forget Jules Verne’s classic, From the Earth to the Moon, and how it anticipated that humans would one day walk on the Moon? Almost a century later, this dream would be realized with the Apollo Program.

The latest comes from Cornell University, where a team of researchers has developed a novel in-suit urine collection and filtration system inspired by the suits the Fremen wore in Frank Herbert’s Dune. Once integrated into NASA’s standard spacesuit—the Extravehicular Mobility Unit (EMU)—this system has the potential to provide astronauts with additional water while reducing the risk of hygiene-related medical events. In short, the stillsuit technology has the potential to enable longer-duration missions on the surface of the Moon, Mars, and orbit.

NASA has big plans for the Moon. Through the Artemis Program, NASA plans to create a program of “sustained exploration and lunar development.” This will include the creation of the Lunar Gateway, an orbital habitat that will facilitate missions to and from the surface, and the Artemis Base Camp that will allow for extended stays. Through its Commercial Lunar Payload Services (CLPS) program, NASA has contracted with commercial partners like SpaceX and Blue Origin to deliver scientific experiments and crew to the lunar surface.

However, these efforts are expected to culminate in the creation of a permanent outpost and human presence on the Moon. This will require far more in the way of crew and payload services to ensure crews can be sustained in the long run. In a recent white paper, “Lunar Surface Cargo,” NASA researchers identified a significant gap between current cargo delivery capabilities and future demand. The paper indicates that this growing cargo demand can only be met by creating a “mixed cargo lander fleet.”

Does proton decay exist and how do we search for it? This is what a recently submitted study hopes to address as a team of international researchers investigate a concept of using samples from the Moon to search for evidence of proton decay, which remains a hypothetical type of particle decay that has yet to be observed and continues to elude particle physicists. This study holds the potential to help solve one of the longstanding mysteries in all of physics, as it could enable new studies into deep-level and the laws of nature, overall.

The Artemis Program represents NASA’s effort to return to the Moon. One of the goals of the project is to set up long-term exploration of the Earth’s only natural satellite. This will need much bulkier equipment than what the Apollo astronauts carried though, and this equipment needs to be transported to the Moon’s surface. Blue Origin and SpaceX, contracted by NASA to provide human landing systems, have begun developing vehicles that can safely deliver this equipment from space to the Moon’s surface.

Back in December, NASA officials, space industry experts, members of the academic community, and science communicators descended on Washington, D.C., for the Achieving Mars Workshop X (AM X). This workshop is hosted by Explore Mars Inc., a non-profit organization dedicated to bringing leading experts from disparate fields together to contribute to creating the first crewed missions to Mars. On May 17th, the results of this year’s workshop were summarized in a report titled “The Tenth Community Workshop for Achievability and Sustainability of Human Exploration of Mars.”

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!
