During the Apollo Era, astronauts conducted vital science operations on the Moon, which included bringing samples of lunar rocks back to Earth for study. Thanks to the examination of these rocks, scientists were able to learn a great deal about the formation and evolution of the Moon and even found evidence of lunar water. In the coming years, when NASA sends astronauts back as part of Project Artemis, more samples will be returned.
Recently, NASA put out the call for science white papers to help them design a framework for the kind of science operations the Artemis astronauts will conduct. According to one proposal, the Artemis astronauts should not only bring back samples of lunar regolith or rocks but lunar ice as well. By examining them here on Earth, scientists may finally be able to resolve the mystery of where the Moon’s water came from.

As part of Project Artemis, NASA intends to send the first woman and the next man to the Moon by 2024, in what will be the first crewed mission to the lunar since the Apollo Era. By the end of the decade, NASA also hopes to have all the infrastructure in place to create a program for “sustainable lunar exploration,” which will include the Lunar Gateway (a habitat in orbit) and the Artemis Base Camp (a habitat on the surface).
Part of this commitment entails the recovery and use of resources that are harvested locally, including regolith to create building materials and ice to create everything from drinking water to rocket fuel. To this end, NASA has asked its commercial partners to collect samples of lunar soil or rocks as part of a proof-of-concept demonstration of how they will scout and harvest natural resources and conduct commercial operations on the Moon.

It takes oxygen to make iron rust. So when scientists discovered hematite spread widely through lunar high latitudes, they were surprised. How did that happen?
A new study suggests that oxygen from Earth could be playing a role in rusting the Moon.

When astronauts return to the Moon in the next few years (as part of Project Artemis) they will be scouting locations and resources around the South Pole-Aitken Basin that will eventually help them to stay there. In this cratered, permanently-shadowed region, water ice has been found in abundance, which could one-day be harvested for drinking water, irrigation, and the creation of oxygen gas and rocket fuels.
A critical aspect to planning for all or this is to consider how future missions may affect the local environment. Based on new research from a team of planetary scientists and engineers, a major risk comes in the form of contamination by lunar landers. In short, exhaust from these vehicles could spread around the Moon and contaminate the very ices the astronauts hope to study.

Could lava tubes on the Moon and Mars play a role in establishing a human presence on those worlds? Possibly, according to a team of researchers. Their new study shows that lunar and Martian lava tubes might be enormous, and easily large enough to accommodate a base.

No matter where you are, where you’ve been and where you’re going, it’s always good to see home. And we all love seeing pictures of our home planet, as seen from space.

For many of us, gardening has been a therapeutic distraction during this time of pandemic quarantine. But some researchers from the Jet Propulsion Lab have been gardening at home with a specific goal in mind: growing food on the Moon.

In the coming years, multiple space agencies will be sending missions (including astronauts) to the Moon’s southern polar region to conduct vital research. In addition to scouting resources in the area (in preparation for the construction of a lunar base) these missions will also investigate the possibility of conducting various scientific investigations on the far side of the Moon.
However, two prominent scientists (Dr. Karan Jani and Prof. Abraham Loeb) recently published a paper where they argue that another kind of astronomy could be conducted on the far side of the Moon – Gravitational Wave astronomy! As part of NASA’s Project Artemis, they explain how a Gravitational-wave Lunar Observatory for Cosmology (GLOC) would be ideal for exploring GW in the richest and most challenging frequencies.

Natural processes here on Earth continually re-shape the planet’s surface. Craters from ancient asteroid strikes are erased in a short period of time, in geological terms. So how can researchers understand Earth’s history, and how thoroughly it may have been pummeled by asteroid strikes?
Scientists can turn their attention to our ancient companion, the Moon.

According to the Giant Impact Hypothesis, the Moon formed when a Mars-sized object (named Theia) collided with Earth billion years ago, at a time when the Earth was still a ball of magma. This event not only led to the Earth-Moon system we recognize today, it is also beleived to have led to the differentiation of the Earth’s core region into an molten Outer Core and a solid Inner Core.
However, there has been an ongoing debate as to the timing of this impact and how long the subsequent formation of the Moon took place. According to a new study by a team of German researchers, the Moon formed from a magma ocean that took up to 200 million years to solidify. This means that the Moon finished forming about 4.425 billion years ago, or 100 million years later than previously thought.
