Watch our interview with two International Space Station astronauts

A United Launch Alliance Atlas 5 rocket blasted off from Cape Canaveral at 11:05 p.m. EDT (0305 GMT) tonight to send Orbital ATK’s commercial Cygnus cargo freighter to the International Space Station. Follow the mission in our live journal.

Astra officials said Saturday a software fix will likely resolve a guidance system problem that caused the company’s first orbital-class rocket to begin drifting off course soon after liftoff from Alaska Friday night, prompting a range safety officer to terminate the mission.

The Starlink 12-17 mission carried 13 Starlink V2 Mini satellites that feature Direct to Cell capabilities. Liftoff from pad 39A at NASA’s Kennedy Space Center happened Saturday, April 12, at 8:53 p.m. EDT (1253 UTC).
