The Artemis II mission, which will return US astronauts to lunar space, has run into problems that have critics demanding NASA remove the crew from the flight for safety reasons. The bigger question is, why do we have astronauts at all?

One of the big challenges in building a space rover is ensuring it doesn't break down out there. Aerospace engineers have designed a flexible wheel for rovers that doesn't require an air-filled tube, can change its size, and can take a real beating.

As if hard vacuum, intense cosmic radiation, corrosive dust, meteors, and temperatures whiplashing hundreds of degrees between night and day weren't enough, personnel at future Moon bases will be at significant peril from moonquakes.

Radio astronomers like a bit of peace and quiet, so they're sending an historic first radio telescope to the Moon. To block out Earthside radio signals, the Lunar Surface Electromagnetics Experiment (LuSEE-Night) will set up shop on the far side of the Moon.

A US startup is looking to our closest satellite to fill a resources gap here on Earth. Interlune and partner Vermeer have revealed a full-scale excavator prototype that forms a key component of its lunar resource Harvester.

The release of NASA's latest budget reveals the Orion spacecraft and Lunar Gateway space station are getting the chop. The US$18.8-billion total figure decreases spending by $6 billion, or 24%, as the space agency increases funding for crewed Moon and Mars missions.

NASA has successfully tested an electric force field on the Moon that protects spacecraft from destructive lunar dust. The Electrodynamic Dust Shield (EDS) was carried aboard Firefly Aerospace’s Blue Ghost Mission 1, whose mission ended on March 16.

The Artemis II and III missions slated to return US astronauts to the Moon have been set back. At a press conference, NASA officials said that problems with the heat shield and life support systems would delay the launches until 2026 and 2027.

Our solar system might still bear the scars from an extremely close shave with an alien star. Such an encounter – the closest pass we know of – would have shaken up objects on the outskirts and might even mean there’s no Planet Nine after all.

Honeybee Robotics has outlined a plan to build a kind of power grid on the Moon, with a network of Statue of Liberty-sized towers containing solar panels and batteries that provide power and communications, and even act as streetlights.

When you live on the Moon, your only option for commuting back to Earth or on to Mars will be some kind of rocket. But each launch will kick up a hellstorm of debris. Building walls to contain the mess could be a perfect job for autonomous rovers.

If you've wondered where future Moon explorers will live, it may be in natural caves deep beneath the lunar crust. Radar data from NASA's Lunar Reconnaissance Orbiter confirms that giant lava tubes lead to tunnels large enough to house entire bases.
