Way, way back in the days when men wore beards and wide-lapelled suits in exotic colors, only NASA had access to photovoltaics and ‘solar’ meant solar thermal. In those days of appropriate technology, it was thought that the ultimate in thermal mass was a phase-change material– a salt or wax that in melting and re-freezing

Four astronauts will have to wait a little longer before launching on their historic mission to the moon. Their rocket, the Space Launch System (SLS), rolled back from Launch Complex-39B (LC-39B) to the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center (KSC) in Florida today (Feb. 25). It’s now safely tucked inside the VAB’s

NSF–DOE Vera C. Rubin Observatory, jointly funded by the U.S. National Science Foundation (NSF) and the U.S. Department of Energy’s Office of Science (DOE/SC), has released its first alerts documenting astronomical events spotted by the observatory. Rubin issued 800,000 alerts the night of 24 February. These alerts called scientists’ attention to new asteroids, exploding stars,

NASA hauled its Artemis II moon rocket off its seaside pad Wednesday for a slow trip back to a processing facility to track down and fix a helium pressurization problem that delayed launch of four astronauts on a flight around the moon from this month to at least April 1. A 6.6-million-pound Apollo-era crawler-transporter rolled
The Voyager 1 satellite is one of the fastest human-made objects, beating anything else made on Earth by a considerable margin – but it’s hard to put that speed into perspective. It’s also the most distant human-made object from our planet. At the time of writing, it is traveling through the galaxy around 15 billion miles
Researchers have finally determined the shape of the heliosphere, the magnetic bubble that protects our Solar System from galactic radiation. Unlike previous models, this zone, generated by solar wind, is neither perfectly spherical nor oval, but adopts an unprecedented shape that resembles a “deflated crescent.” The heliosphere, an invisible shield that stretches far beyond the
Chinese astronauts have described what happened when they were nearly stranded in space last year after a suspected piece of space junk struck their return capsule. Chen Dong, Chen Zhongrui and Wang Jie, the crew of the ill-fated Shenzhou-20 mission, were preparing to leave China‘s Tiangong space station and return to Earth on Nov. 5,
