Orbiting above Earth attached to the Delta IV second stage, Orion’s telemetry shows all systems working well on NASA’s newest spacecraft designed for astronauts. The next major stages in the flight test will begin with the re-ignition of the second stage engine. That 4 1/2-minute burn will send Orion out of low Earth orbit and on a path to fly 3,600 miles high before returning to Earth. The flight test is scheduled to end with Orion splashing down in the Pacific Ocean at about 11:29 a.m. EST.
The Orion spacecraft and attached second stage of the Delta IV Heavy are working as planned and the combination has been placed in a slow roll to keep temperatures balanced as Orion moves through orbit.
The second stage engine completed its first burn and Orion is in orbit now, on a path that is about 560 miles by 120 miles above Earth. There will be another burn by the Delta IV second stage to lift its orbit and then push it out 3,600 miles from Earth. For now, though, Orion begins a coast phase of about 97 minutes. The second stage will reignite at the 1 hour, 55 minute, 26 second point of the mission. The coast phase will allow flight controllers to continue evaluating telemetry coming down from the spacecraft and make sure Orion is healthy thus far in its mission.
Orion is soaring over Earth at 15,000 mph on its way to its preliminary orbit. The second stage engine will cut off in about four minutes.
