WALLOPS ISLAND, Va. - NASA is reviewing data from a rocket launch that tested a new sub-payload deployment method for suborbital rockets.

NASA says a Black Brant IX suborbital rocket was launched at 5 a.m. Thursday from the agency's Wallops Island Flight Facility on Virginia's Eastern Shore.

The new deployment method uses small rocket motors to eject sub-payloads from a rocket's main payload. Thursday's test included releasing vapour traces in space.

The NASA Sounding Rocket Program Office is reviewing data on the test's performance.
