NASA will build its lunar base camp on the moon’s south pole

When NASA sends astronauts to the moon for its Artemis program, it isn’t just planning to send them for brief visits. The plan is to set up a long-term moon base, where astronauts could stay for weeks or months at a time. The agency has been considering locations for this base and has narrowed down the options to focus on the moon’s south pole.

The pole is an appealing option because it is close to many of the dark craters which are thought to contain water ice. But there is also a need to pick a spot that receives sunlight so it can power the solar panels which will provide power for the base. So the location needs to have a balance of dark and illuminated areas.

“One idea is to set up camp in an illuminated zone and traverse into these craters, which are exceptionally cold,” said NASA Goddard planetary scientist Daniel P. Moriarty, who’s involved with NASA’s South Pole site analysis and planning team, in a statement.

The south pole is a good option for this as sunlight hits it at a low angle, meaning there are still craters that remain in shadow even when there is sunlight in the area.

The other consideration when picking a location for a base camp is how easy it is to land there. Landing on the moon is still challenging, 50 years after it was first achieved, because lunar terrain is uneven which makes it unsuited for landings. Ideally, it would be best to land on a flat region. “You want to land in the flattest area possible, since you don’t want the landing vehicle to tip over,” Moriarty said.

Finally, another issue is how to space out the habitat for the astronauts from other parts of the base camp like the landing area and solar panels. “You want to take advantage of the landforms, such as hills, that can act as barriers to minimize the impact of contamination,” said Ruthan Lewis, a biomechanical and industrial engineer, architect, and a leader on NASA’s South Pole site analysis and planning team. “So, we’re looking at distances, elevations, and slopes in our planning.”

For now, scientists and engineers at NASA will continue honing in on the exact location for a future moon base.

NASA’s axed moon rover could be resurrected by Intuitive Machines

An illustration of NASA's Volatiles Investigating Polar Exploration Rover (VIPER) on the lunar surface.

Lunar scientists were shocked and dismayed last month when NASA announced that it was canceling work on its moon rover, VIPER. The Volatiles Investigating Polar Exploration Rover was intended to search the moon's south pole for evidence of water there, but NASA said that it had to ax the project due to increasing costs.

This week, an open letter to Congress called the cancellation of the mission "unprecedented and indefensible," and questioned NASA's assertion that the cancellation of the mission would not affect plans to send humans to the moon. Scientists argued that the mission was fundamental to understanding the presence of water on the moon, which is a key resource for human exploration, as well as an issue of scientific interest.

NASA’s mega moon rocket has just begun a 900-mile journey

The core stage of NASA's SLS rocket.

NASA’s powerful Space Launch System (SLS) rocket is set to blast four astronauts to space next year on the epic Artemis II mission that will come within about 80 miles of the lunar surface.

In preparation for the mission, the rocket’s 213-foot-tall (65 meters) core stage has just embarked on a rather more leisurely journey -- on a barge heading for the Kennedy Space Center in Florida.

NASA axes its moon rover project VIPER

NASA has announced it is scrapping its plans to send a rover to the moon. The Volatiles Investigating Polar Exploration Rover, or VIPER, project was intended to search the moon's polar regions for water, but will now be shelved due to budget issues. Originally slated to land on the moon in December 2022, the project had been delayed several times, and the most recent update was that it would not be ready until September 2025.
