People who came to Wallops Island, Virginia, to watch the launch walk away after the unmanned rocket, owned by Orbital Sciences Corp., exploded. 
The rocket and spacecraft -- which together cost more than $200 million, according to Frank Culbertson, the general manager of Orbital's Advanced Programs Group -- are gone. 
The rocket had been set to go up Monday, only to be scrubbed "because of a boat downrange in the trajectory Antares would have flown had it lifted off," according to NASA. Coast Guard spokesman David Weydert said the boat that triggered the postponement was 40 miles offshore. Tuesday, by contrast, seemed perfect. Just before liftoff, NASA reported "100% favorable" weather and "no technical concerns with the rocket or spacecraft being worked." 
An aerial view of the Wallops Island facility is seen October 29 after the failed launch. 
The Antares rocket, with the Cygnus spacecraft on board, is seen on Launch Pad-0A after the launch attempt was scrubbed on October 27. 
The Orb-3 mission's payload fairing (essentially the casing around the spacecraft) was installed on the Antares on October 23. 
The payload fairing goes onto the spacecraft. Orbital will lead the investigation of the accident, along with the FAA, with NASA assisting. Among other things, they'll try to collect and examine any debris that can be recovered, review data from the spacecraft before its destruction and look at videos around the launch time.
