A permanent lunar base will require structures resilient enough to withstand everything from cosmic radiation and micro-meteorites to moonquakes. There are plenty of building materials to choose from on Earth, but they all come with a catch: transportation storage aboard spacecraft is limited, and each additional pound of cargo will quickly ramp up costs. Engineers
The LISA (Laser Interferometer Space Antenna) observatory, now in development, will detect gravitational waves, the tiny ripples in space-time caused by orbiting masses. Now two studies led by NASA astrophysicists show in new detail how LISA could reveal a new and unique population of exoplanets — worlds beyond our solar system — throughout our galaxy.
Launched nearly 50 years ago in 1977, NASA’s Voyager 1 on Wednesday, Nov. 18 will have traveled one light-day from Earth, which is more than 16 billion miles (25.9 billion kilometers). Voyager 1 is the most distant human-made object, and any light from Earth would take 24 hours to reach the spacecraft. NASA will highlight
NASA will welcome home the Expedition 74 crew during a public event at Space Center Houston following their return from a long-duration mission aboard the International Space Station. NASA astronauts Jessica Meir, Jack Hathaway, and Chris Williams; ESA (European Space Agency) astronaut Sophie Adenot; and Roscosmos cosmonauts Sergey Kud‑Sverchkov and Sergei Mikaev will share mission
A 28-year-old man got a little bit more than he bargained for after a life-saving brain surgery. Karl (last name withheld for privacy) sees features of his grey tabby cat, Luna, on the human faces he encounters throughout the day. He’ll see Luna’s almond-shaped eye sockets, enlarged pupils, or stripes on humans, if her face
The Crew Health and Performance Exploration Analog (CHAPEA) Mission 2 crew arranged photos around a boot print in the simulated Martian sand outside their habitat on Aug. 31, 2026. The crew recently exited their habitat on Saturday, Oct. 31, after 378 days of isolation in a facility at the agency’s Johnson Space Center in Houston. Health
