Gallery: Antares rocket explodes

A Northrop Grumman Cygnus supply ship arrived at the International Space Station on Monday with more than 8,000 pounds of cargo, including new astronaut sleeping quarters, parts for the station’s toilet, and numerous biomedical and technology experiments.

With investigators zeroing in on a decades-old rocket engine as the cause of a catastrophic launch mishap, Orbital Sciences officials said the company plans to use other launchers to send cargo to the International Space Station while modifying its Antares rocket with a new propulsion system.

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.
