The reaction control thrusters used are located on the sides of the service module and can be fired individually as needed to move the spacecraft in different directions or rotate it into any position. Each of these engines provides about 50 pounds of thrust.
A few key milestones for Orion remain, including the entry system checkouts and propulsion system leak checks on mission days 24 and 25, respectively. Orion will travel at around 25,000 mph while reentering Earth’s atmosphere, testing the world’s largest ablative heat shield by reaching temperatures up to 5,000 degrees – approximately half the temperature of the surface of the sun. The heat shield is located at the bottom of the Orion capsule, measuring 16.5 feet in diameter, and sheds intense heat away from the crew module as Orion returns to Earth.
On Thursday, December 8 at 5 p.m. EST, NASA will host a briefing to preview Orion’s return scheduled for Sunday, December 11 and to discuss how the recovery teams are preparing for entry and splashdown. The briefing will be live on NASA TV, the
