Gallery: Antares rocket explodes

United Launch Alliance has granted “flight clearance” for its workhorse Atlas 5 rocket to resume satellite deployments after linking an errant valve with the fuel usage crunch on its most recent mission and tweaking subsequent vehicles.

A Northrop Grumman Cygnus supply ship — named the S.S. Katherine Johnson for the trailblazing NASA mathematician portrayed in “Hidden Figures” — was loaded with time-sensitive cargo Friday at a launch pad in Virginia for a midday blastoff Saturday toward the International Space Station.

The International Space Station received more than 2.5 tons of fresh supplies and experiments Sunday with the arrival of a commercial Cygnus cargo vessel after an automated laser-guided rendezvous.
