Gallery: Antares rocket explodes

The first launch of Orbital ATK’s redesigned Antares rocket since an engine failure doomed a mission in 2014 will likely be delayed more than one month until August to complete analysis of data acquired during a first stage hotfire test, officials said.

An Atlas 5 rocket successfully launched another Cygnus cargo freighter for Orbital ATK Tuesday night, fulfilling the booster’s role of reestablishing America’s resupply link to the International Space Station.

Northrop Grumman’s Cygnus supply ship set for liftoff Saturday will deliver to the International Space Station the final hardware for a series of ambitious spacewalks later this month to install a new coolant system on the Alpha Magnetic Spectrometer, a $2 billion particle physics experiment seeking the cosmic signatures of dark matter and antimatter.
