LOS ANGELES - NASA has secured the area around the Wallops Flight Facility in Virginia to begin its investigation into why an Orbital Sciences Antares rocket blew up just seconds after liftoff on its way to deliver a Cygnus cargo spacecraft to the International Space Station (ISS).
The vehicle, which is powered at launch by two refurbished AJ-26 rocket engines, suffered a “catastrophic anomaly shortly after lift-off,” the agency says. The mission was to have been the third Orbital resupply flight to the ISS. It carried 5,000 lb. of NASA cargo, and had been delayed from a previous attempt on Oct. 27 because of a boat straying into the range safety zone southwest of the launch pad.
Investigations are expected to focus initially on potential failure mechanisms involving the AJ-26, a liquid oxygen/kerosene-powered engine originally developed for the Russian space program as the NK-33. An AJ-26 slated to power an Antares on a mission to the ISS in 2015 experienced a failure during a hot-fire test at NASA’s Stennis Space Center in Mississippi on May 22.
The failure occurred around 10 sec. after liftoff at 6:22 pm. EDT, resulting in an explosion very close to the launch facility itself. Images of the site show burning debris littering the pad area and the adjacent beach on the Atlantic coast. NASA says the range confirms launch officials are “working to secure the area and data from their consoles to use in the coming investigations. All personnel are accounted for and there have been no injuries.”
