Photos: Delta 2 rocket blasts off with SMAP satellite

SpaceX is targeting Jan. 7 for launch of its first Crew Dragon commercial ferry ship on an unpiloted test flight to the International Space Station, NASA announced Wednesday, a major milestone in the agency’s drive to end its sole reliance on Russian Soyuz crew ships for carrying astronauts to orbit.

Leaving six crewmates behind in orbit, a Russian commander, his NASA co-pilot and a first-time flier from the United Arab Emirates undocked from the International Space Station early Thursday, executed a fiery plunge back to Earth and landed safely on the steppe of Kazakhstan.

United Launch Alliance called off a launch attempt Monday after hitting a snag during preparations to fill an Atlas 5 rocket with cryogenic propellants at Cape Canaveral, delaying the liftoff of a new U.S. Space Force infrared surveillance satellite until no earlier than Tuesday.
