Live coverage: Three-man crew docks with space station

Northrop Grumman’s Antares rocket will deliver a Cygnus supply ship into orbit Saturday to begin a two-day pursuit of the International Space Station.

These photos were taken on Wednesday, Dec. 2, approximately 24 hours before the scheduled liftoff of the United Launch Alliance Atlas 5 rocket from Cape Canaveral’s Complex 41 with Orbital ATK’s commercial Cygnus cargo ship bound for the International Space Station.

In another first on Mars, an instrument inside NASA’s Perseverance rover has made oxygen out of carbon dioxide sucked in from the planet’s atmosphere, officials said Wednesday. The technology could help future astronauts “live off the land” by generating their own rocket fuel and breathing air.
