ORB-3 “Deke Slayton” will not be reaching orbit. 😦 In the first failure for the Commercial Access To Space program that manages the two commercial cargo carriers to the ISS, the Antares rocket exploded above Wallops Island this evening, just fifteen seconds into the flight. The solid upper stage appears to catch fire in the conflagration, resulting in a quite spectacular accident. I very much doubt there will be much salvageable from the Cygnus spacecraft; it’s quite a big explosion. Very unfortunate for both NASA and the Orbital Sciences team.
