Wayward plane blocks space station launch

The Orbital ATK Antares rocket on the pad at the Mid-Atlantic Regional Spaceport (MARS) at NASA's Wallops Island, Va., flight facility moments after a launch abort was declared.


The launch of an Orbital ATK Antares rocket carrying a Cygnus cargo ship bound for the International Space Station was scrubbed at the last minute Saturday when an aircraft strayed into the restricted launch danger zone.

The countdown was ticking smoothly toward zero at 7:37 a.m. EST (GMT-5) when a flight controller suddenly called out to the launch conductor, saying "LC, LC, we are red. We have an aircraft in the hazard area."

"Copy that," the launch conductor calmly replied. "Abort, abort, abort, this is LC on the countdown net, abort, abort, abort, proceed to the abort safing checklist."

Engineers immediately began backing out of the countdown at the Mid-Atlantic Regional Spaceport (MARS) at NASA's Wallops Island, Va., flight facility.

It was not immediately known whether the intruder was a private plane or a commercial aircraft. The FlightAware website showed several commercial jets in transit over the Atlantic Ocean east and southeast of the launch site, but it was not known if any of them were to blame.

In any case, flight rules for rocket launches forbid takeoff if there is any chance a malfunctioning booster could threaten life or property.

Orbital ATK will make another attempt to launch the company's eighth operational space station resupply mission at 7:14:52 a.m. Sunday. Forecasters are predicting cold but acceptable weather.

If all goes well, the Cygnus will reach the space station around 4:45 a.m. Tuesday, roughly the same time NASA and United Launch Alliance plan to launch a Delta 2 rocket from Vandenberg Air Force Base, Calif., to put a NOAA polar orbiting weather satellite into orbit.
