The cause of the issue, according to NASA, was with a timing system.
Bridenstine said the mission elapsed timing system had an anomaly, so the vehicle thought it was a different time when it was supposed to fire the engines.
NASA officials said they were eventually able to get the engines burning and the spacecraft is in orbit and doing well.
Doing so well that it won't rendezvous with the ISS and will be returning early. Sounds like NASA officials are taking over the role of the Boeing smoke and mirrors department.
