Photos: America’s 100th EELV blasts off

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Tuesday, heading due east over the Atlantic Ocean to deliver the Hispasat 30W-6 communications satellite into orbit around 33 minutes later.

Northrop Grumman called off the launch of an Antares rocket and a Cygnus space station cargo freighter Thursday night on Virginia’s Eastern Shore, the third aborted countdown in less than 24 hours for three different U.S. rockets.

Russian investigators believe a malfunction during separation of the Soyuz rocket’s four liquid-fueled first stage boosters two minutes after liftoff from Kazakhstan led to an emergency landing of a two-man crew heading for the International Space Station, officials said Friday.
