SLS cryogenic tanking test preps begin this weekend
Final preparations began this weekend at NASA's Stennis Space Center in Mississippi to load super-cold liquid hydrogen and liquid oxygen into the massive core stage of the Space Launch System heavy-lift rocket for the first time as soon as Monday.
Arecibo Observatory collapses as scientists lament loss of deep space radar
The 900-ton suspended platform of Puerto Rico's famed Arecibo Observatory collapsed Tuesday after cable failures, crashing into the radio telescope's iconic dish and shattering a research instrument used to study pulsars, galaxies, planets, and asteroids that might threaten Earth.
Photos: Falcon 9 launches and lands at Vandenberg Air Force Base

VideoLive coverage: Chinese sample return spacecraft completes docking in lunar orbit
After launching Nov. 23 and arriving in lunar orbit over the weekend, China's Chang'e 5 sample return mission landed on the moon Tuesday, targeting a volcanic region in the Oceanus Procellarum region. On Thursday, the craft's ascender vehicle took off to begin the trip back to Earth, followed by a successful docking with the mission's return vehicle in lunar orbit Saturday.
International satellite launches to extend measurements of sea level rise
A European-built satellite with the unusual shape of a house launched into orbit Saturday aboard a SpaceX Falcon 9 rocket from California's Central Coast, carrying a sophisticated radar altimeter to measure rising sea levels on our home planet.

Check out photos of the encapsulation of the Sentinel-6 Michael Freilich oceanography satellite inside the payload shroud of a SpaceX Falcon 9 rocket before its launch from Vandenberg Air Force Base, California.
VideoLive coverage: SpaceX launches oceanography satellite from California
A SpaceX Falcon 9 rocket lifted off from Space Launch Complex 4-East at Vandenberg Air Force Base in California at 12:17 p.m. EST (9:17 a.m. PST; 1717 GMT) Saturday with an oceanography satellite jointly developed by U.S. and European space and weather agencies. The rocket's first stage booster returned to a bullseye landing back at Vandenberg.
Crew-rated SpaceX booster returns to Cape Canaveral with a lean
The Falcon 9 booster that launched four astronauts toward orbit last weekend arrived back on Florida's Space Coast Thursday aboard a SpaceX drone ship, sailing into Port Canaveral with a lean but otherwise in seemingly good shape after it apparently slid across the ship's deck in high winds and rough seas. Assuming post-flight inspections reveal no major issues, SpaceX aims to reuse the booster to launch the next Crew Dragon mission in 2021.
