After the Red Planet reemerged from conjunction — a period when NASA doesn't communicate with spacecraft because Mars is behind the sun from Earth's point of view in space — scientists began planning a rare type of experiment for the Curiosity rover. The robot has only conducted it once before in the 13 years it has roamed Mars.

A new paper suggests that BARSOOM may have been alive on the planet, and was killed in the Viking experiments.

Nasa is using the SpaceX Crew-12 mission to find out if a pilot can still fly a multi-billion-pound spacecraft while feeling this level of motion sickness. To do this, they are using a high-tech experiment called Manual Piloting.

Artemis II astronauts will carry personal radiation sensors in their pockets, while detectors mounted throughout the cabin will track exposure levels. Additional monitors developed with the German Space Agency will measure high-energy particles believed to pose increased health risks.

Artemis II, the next mission in NASA’s Artemis program to explore the Moon, is scheduled to launch from Florida within the coming weeks. The mission will be the first crewed mission to the vicinity of the Moon since 1972, with the four-person crew expected to travel farther than any other human mission in spaceflight history.

NASA will launch two crewed missions in early February, sending astronauts to the ISS to prepare for Mars missions and another crew to orbit the moon.

NASA presents a plan to explore the interior of the Moon using robotic experiments, without the need for astronauts.

CAPE CANAVERAL, Florida -- April's total solar eclipse promises to be a scientific bonanza, thanks to new spacecraft and telescopes, and cosmic chance. The moon will be extra close to Earth, providing a long and intense period of darkness, and the sun ...

Unusual experiments with drug-influenced spiders revealed that caffeine distorted web-building more than any other substance, a finding later explored by NASA to measure toxicity.
