By the end of this decade, NASA, the Chinese National Space Agency (CNSA), Roscosmos, and other space agencies plan to establish a sustained human presence on the Moon. A crucial aspect of these plans is using local resources (particularly water) to lessen dependence on Earth, a process known as in-situ resource utilization (ISRU). Hence why NASA plans to establish a base of operations around the lunar south pole, a heavily cratered region where water ice exists in abundance in permanently shadowed regions (PSRs).

To harvest water ice and other resources successfully, NASA is investing in technologies that will enable cost-effective sample collection, in-situ testing (with or without astronaut oversight), and real-time data transmission to Earth. One such technology is the Lunar PlanetVac (LPV), a sample acquisition and delivery system designed to collect and transfer lunar regolith to sample containers without reliance on gravity. The LPV is one of 10 payloads that will be flown to the lunar surface as part of NASA’s Commercial Lunar Payload Services (CLPS) program.

On July 14th, 2015, the New Horizons probe made history by accomplishing the first flyby of Pluto and its largest satellite, Charon. The stunning images this mission took of these icy worlds have helped scientists address some of the key questions about Pluto and its massive moon, which have been shrouded in mystery for decades (owing to their great distance from Earth). One of the biggest mysteries that scientists have contemplated since Charon was first discovered in 1978 is how it came together with Pluto in the first place.

For decades, astronomers suspected that Pluto and Charon formed through a process similar to Earth and the Moon. This theory, known as the Giant Impact Hypothesis, states that roughly 4.5 billion years ago, primordial Earth was struck by a Mars-sized body named Theia. In a new study, a team of researchers from the University of Arizona challenged this assumption and offered an alternate theory known as “kiss and capture.” Their findings could help scientists better understand how planetary bodies in the outer Solar System form and evolve.

Between NASA, other space agencies, and the commercial space sector, there are some truly ambitious plans for humanity’s future in space. These plans envision the creation of permanent infrastructure on and around the Moon that will enable a permanent human presence there, complete with research, science, and commercial operations. They also call for the first crewed missions to Mars, followed by the creation of surface habitats that will allow for return visits. These plans present many challenges, ranging from logistical and technical issues to health and human safety.

Another challenge is coordinating operations across the lunar surface with those in orbit and back at Earth, which requires a system of standardized time. In a recent study, a team of NASA researchers developed a new system of lunar time for all lunar assets and those in cis-lunar space. They recommend that this system’s foundation be relativistic time transformations, known more generally as “time dilation.” Such a system will allow for coordination and effective timekeeping on the Moon by addressing discrepancies caused by gravitational potential differences and relative motion.

A New Mission Watches Meteoroids Hit the Far Side of the Moon

Sometimes, it’s hard to remember that Earth is constantly being bombarded by literally tons of space debris daily. The larger bits form what we know as shooting stars, and most burn up in the atmosphere. Still, throughout our planet’s history, giant versions have caused devastation unlike anything else seen on this planet. Tracking these types of objects is typically done from the Earth, but a new mission set out by researchers in Italy has a novel idea – why not try to learn more about potential impactors by watching them hit the far side of the Moon?

In the coming years, NASA and other space agencies will send humans back to the Moon for the first time since the Apollo Era—this time to stay! To maximize line-of-sight communication with Earth, solar visibility, and access to water ice, NASA, the ESA, and China have selected the Lunar South Pole (LSP) as the location for their future lunar bases. This will necessitate the creation of permanent infrastructure on the Moon and require that astronauts have the right equipment and training to deal with conditions around the lunar south pole.

This includes lighting conditions, which present a major challenge for science operations and extravehicular activity (EVA). Around the LSP, day and night last for two weeks at a time, and the Sun never rises more than a few degrees above the horizon. This creates harsh lighting conditions very different from what the Apollo astronauts or any previous mission have experienced. To address this, the NASA Engineering and Safety Council (NESC) has recommended developing a wide variety of physical and virtual techniques that can simulate the visual experiences of Artemis astronauts.

Through the Artemis Program, NASA will send the first astronauts to the Moon since the Apollo Era before 2030. They will be joined by multiple space agencies, like the ESA and China, who plan to send astronauts (and “taikonauts”) there for the first time. Beyond this, all plan to build permanent habitats in the South Pole-Aitken Basin and the necessary infrastructure that will lead to a permanent human presence. This presents many challenges, the most notable being those arising from the nature of the lunar environment.

Aside from the extremes in temperature, a 14-day diurnal cycle, and the airless environment, there’s the issue of lunar regolith (aka moondust). In addition to being coarse and jagged, lunar regolith sticks to everything because it is electrostatically charged. Because of how this dust plays havoc with astronaut health, equipment, and machinery, NASA is developing technologies to mitigate dust buildup. Seven of these experiments will be tested during a flight test using a Blue Origin New Shepard rocket to evaluate their ability to mitigate lunar dust.

Through the Artemis Program, NASA hopes to lay the foundations for a program of “sustained lunar exploration and development.” This will include regular missions to the surface, the creation of infrastructure and habitats, and a long-term human presence. To facilitate this, NASA is teaming up with industry and international partners to develop Human Landing Systems (HLS) that can transport crews to and from the lunar surface and landers that can deliver payloads of equipment, vehicles, and supplies to the lunar surface.

In a recent statement, NASA indicated that it intends to award Blue Origin and SpaceX additional work under their existing contracts to develop landers that will deliver equipment and infrastructure to the lunar surface. NASA also plans to assign demonstration missions to these companies, in addition to design certification reviews, which will validate their concepts. This decision builds on NASA’s earlier request, made in 2023, that the two companies develop cargo versions of their HLS concepts, which are currently in development for the Artemis III, Artemis IV, and Artemis V missions.

Before the decade is out, as part of the Artemis Program, NASA plans to send astronauts to the Moon for the first time since the Apollo Era. To realize this goal, they have contracted with commercial space industries to develop all the necessary components. This includes the Space Launch System (SLS) and the Orion spacecraft that will take the Artemis astronauts to the Moon. There’s also the Lunar Gateway and the Artemis Base Camp, the infrastructure that will facilitate regular missions to the Moon after 2028.

In between, NASA has also partnered with companies to develop the Human Landing Systems (HLS) that will transport the Artemis astronauts to the lunar surface and back. This includes the Starship HLS SpaceX is currently developing for NASA, which will rendezvous with the Orion spacecraft in lunar orbit and allow the Artemis III astronauts to land on the Moon (which will take place no sooner than September 2026). In a series of newly-updated images, SpaceX has provided artistic renders of what key moments in this mission will look like.

While new rockets and human missions to the Moon are in the press, NASA is quietly thinking through the nuts and bolts of a long-term presence on the Moon. They have already released two white papers about the lunar logistics they’ll require in the future and are now requesting proposals from companies to supply some serious cargo transportation. But this isn’t just for space transport; NASA is also looking for ground transportation on the Moon that can move cargo weighing as much as 2,000 to 6,000 kg (4,400 to 13,000 pounds.)

China’s space program has advanced considerably since the turn of the century. In addition to developing heavy-launch vehicles like the Long March 5 and building a modular space station in orbit, China has also embarked on an ambitious program of lunar exploration (Chang’e) – which has launched six robotic missions to explore the Moon’s surface since 2007. These missions are paving the way for crewed missions to the Moon by 2030 and creating a permanent habitat around the Moon’s southern polar region – the International Lunar Research Station (ILRS).

They also plan to send crewed missions to Mars by 2033, which will culminate in the creation of a permanent base there too. Earlier today, the Chinese Academy of Sciences (CAS), the China National Space Administration (CNSA), and the China Manned Space Agency (CMSE) jointly released the country’s first long-term scheme for space science and exploration. Titled “National Medium—and Long-Term Development Plan for Space Science (2024-2050),” this plan elaborated on the basic principles, development goals, and roadmap for the country’s space science and exploration through 2050.
