A problem with the main engine on Northrop Grumman’s Cygnus XL spacecraft will keep it from delivering 11,000 pounds of supplies and experiments to the International Space Station as scheduled on Wednesday.
In a statement released Tuesday afternoon, NASA said ground teams are evaluating backup plans that might still allow the Cygnus spacecraft to reach the space station, just not on schedule. The problem arose early Tuesday when the spacecraft’s main engine shut down earlier than expected during two burns to boost the ship’s orbit for its rendezvous with the ISS, according to NASA.
Officials didn’t release any other details about the engine problem, but all other systems on the Cygnus XL spacecraft are performing as designed, NASA said. The agency said a new arrival date and time at the space station is “under review.”
