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.

A Chinese Booster (and Additional Secret Payload) Caused a Double Crater on the Moon

Last year, astronomers warned that a large piece of debris was on a collision course with the Moon. Initially, they speculated that it was a SpaceX booster but later zeroed in on a Chinese Long March 3C rocket booster that launched the Chang’e 5 mission. When it did impact on March 4, 2022, astronomers noted a strange double crater.

A new paper suggests that it couldn’t have been a single object breaking up since there’s no atmosphere on the Moon. Instead, the booster must have been carrying an additional, undisclosed payload.

Simulating How Moon Landings Will Kick Up Dust

When spacecraft land on the Moon, their exhaust strikes the powdery regolith on the lunar surface. The Moon has low gravity and no atmosphere, so the dust is thrown up in a huge plume. The dust cloud could possibly interfere with the navigation and science instruments or cause visual obstructions. Additionally, the dust could even be propelled into orbit, risking other spacecraft nearby.

In working to better understand the impact future landers might have on the lunar surface, NASA has developed a new supercomputer simulation. They used it to predict how Apollo 12’s lunar lander exhaust would interact with regolith, then compared this to the actual results of the landing.

The Lunar Swirl Mystery Deepens

For years, people noticed strange features on the Moon dubbed “Lunar Swirls.” They’re bright regions that appear to be concentrations of lighter-colored material on the surface. It turns out that interactions between the solar wind and magnetic regions on the Moon may play a role at two sites.

Plants Could Grow in Lunar Regolith Using Bacteria

In the next decade, NASA, China, and their international and commercial partners plan to establish habitats on the Moon. Through the Artemis Program, NASA will deploy the orbiting Lunar Gateway and the Artemis Base Camp on the lunar surface. Meanwhile, China (and its partner Roscosmos) will deploy the International Lunar Research Station (ILRS), consisting of an orbital and surface element. The creation of this infrastructure will enable a “sustained program of lunar exploration and development” that could lead to a permanent human presence there.

To ensure that humans can work and live sustainably beyond Earth, astronauts and crews will need to be able to harvest local resources to see to their needs – in-situ resource utilization (ISRU). This includes using lunar water ice and regolith to grow plants, providing astronauts with food and an additional source of oxygen and biomass. To test the potential for growing plants on the Moon, a Chinese research team conducted a series of experiments where they grew tobacco plants in simulated lunar soil with the help of bacteria.

NASA Wants to Learn to Live Off the Land on the Moon

In preparation for the upcoming Artemis missions to the lunar south pole, NASA recently solicited a Request for Information (RFI) from the lunar community to map out its future Lunar Infrastructure Foundational Technologies (LIFT-1) demonstration for developing In-situ Resource Utilization (ISRU) technologies as part of the agency’s ambitious Lunar Surface Innovation Initiative (LSII). The primary goal of LIFT-1, which is being driven by NASA’s Space Technology Mission Directorate (STMD), is to advance ISRU technologies for extracting oxygen from the lunar regolith, including manufacturing, harnessing, and storing the extracted oxygen for use by future astronauts on the lunar surface. Proposals for LIFT-1 became available to be submitted via NSPIRES on November 6, 2023, with a deadline of December 18, 2023.

ESA is Testing a Modular Multipurpose Rover that Could Be a Science Lab or a Tiny Bulldozer

Most rovers have been built for Mars, and each one of them is a complex machine designed with specific goals and terrains in mind. But the Moon is different than Mars. We’re not searching for life there; we’re trying to establish a presence.

In recognition of the difference, the ESA is developing modular rovers that can serve different needs with only small modifications.

Some of the Moon's Craters are From Interstellar Impacts. Can We Tell Which?

By discovering two interstellar objects (ISOs), we know that asteroids and comets from other star systems pass through the Solar System from time to time. By inference, some of these must have crashed into the Moon, creating impact craters. If we could study the impact sites, we might be able to learn about the star systems that they came from.

A new paper suggests there could be a way to determine which lunar craters came from interstellar object impacts. The authors say that young, small craters with high-melt volume near the Moon’s equator are likely the best candidates for ISO-generated craters on the lunar surface.

India Plans to Send Humans to the Moon by 2040

The Indian space program has been on a bit of a tear lately. Chadrayaan-3 was just the latest successful for the ISRO, India’s space agency, when it launched in July – especially juxtaposed with Luna-25, a Russian moon lander mission that launched around the same time and failed spectacularly by crashing into the Moon. Maybe in part due to the ISRO’s success, Indian Prime Minister Narendra Modi appears to have taken an increased interest in the program and recently chaired a meeting to review the Gaganyaan Mission, India’s first foray into crewed space flight. But while in the meeting, he suggested the country’s exploration goals should go further – much further.

Earth is Hiding Another Planet Deep Inside

Earth’s early history is marked by massive collisions with other objects, including planetesimals. One of the defining events in our planet’s history, the formation of the Moon, likely resulted from one of these catastrophic collisions when a Mars-sized protoplanet crashed into Earth. That’s the Giant Impact Hypothesis, and it explains how the collision produced a torus of debris rotating around the Earth that eventually coalesced into our only natural satellite.

New research strengthens the idea that Theia left some of its remains inside Earth.
