NASA/JPL-Caltech This Oct. 4, 2017, illustration shows a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian’s Star or Tabby’s Star. The star has experienced unusual dips in brightness over a matter of days, as well as much subtler but longer-term dimming trends. Scientists proposed several explanations for this unexpected behavior, ranging [...]

This artist’s concept portrays SpaceX’s Starship Human Landing System (HLS) with two Raptor engines lit, performing a braking burn prior to its Moon landing. The burn will occur after Starship HLS departs low lunar orbit to reduce the lander’s velocity prior to final descent to the lunar surface. NASA is working with SpaceX to develop [...]
These artist’s concepts show SpaceX’s Starship Human Landing System (HLS) in operation on its journey to the Moon. Before astronauts launch in NASA’s Orion spacecraft atop the agency’s SLS (Space Launch System) rocket, SpaceX will launch a storage depot to Earth orbit. For Artemis III and Artemis IV, SpaceX plans to complete propellant loading operations [...]

These artist’s concepts show SpaceX’s Starship Human Landing System (HLS) on the Moon. NASA is working with SpaceX to develop Starship HLS to carry astronauts from lunar orbit to the Moon’s surface and back for Artemis III and Artemis IV as part of the agency’s Artemis campaign. At about 165 feet (50 m), Starship HLS [...]
