The countdown for a planned launch of a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida automatically aborted in the last second before liftoff Sunday after an on-board computer detected unexpected data during an engine power check.

Rocket Lab’s first mission of 2020 lifted off from New Zealand’s North Island at 9:56 p.m. EST Thursday (0256 GMT; 3:56 p.m. New Zealand time Friday) with a secret payload for the National Reconnaissance Office, which owns the U.S. government’s fleet of intelligence-gathering spy satellites.

NASA and Northrop Grumman managers at the Kennedy Space Center decided Tuesday to press ahead with final preparations to launch a NASA scientific research satellite early Wednesday aboard an air-launched Pegasus XL rocket off Florida’s east coast.
