NASA Artemis I – Flight Day 20: Orion Spacecraft Conducts Return Powered Flyby

Orion will sprinkle down in the Pacific Ocean on Sunday, December 11. The objective management team surveyed and convened “go” to deploy healing assets off the coast of California ahead of Orions splashdown on December 11. The winch will pull Orion into a specifically created cradle inside the ships well deck and the other lines will manage the motion of the spacecraft. As soon as Orion is placed above the cradle assembly, the well deck will be drained and Orion will be protected on the cradle.
Recovery teams prepare for the splashdown of Orion on December 11, 2022, off the coast of San Diego, California.

Today the group achieved another special achievement, flying Orion simply 80 miles from the surface area of the Moon. “When Orion returns to Earths atmosphere in just a couple of days, it will come back hotter and much faster than ever before– the supreme test prior to we put astronauts on board.
A number of hours prior to the lunar flyby, the spacecraft performed a trajectory correction burn at 4:43 a.m. CST utilizing the response control system thrusters on the service module. The burn lasted 20.1 seconds and altered the velocity of the spacecraft by 1.39 miles per hour (2.04 feet per second) or 2.24 km/h (0.62 meters per second).
On the 20th day of the Artemis I mission, Orion completed the 3-minute, 27-second, return powered flyby burn, making its closest technique just 80 miles above the lunar surface area. Orion will splash down in the Pacific Ocean on Sunday, December 11. Credit: NASA
The objective management group convened and surveyed “go” to deploy healing assets off the coast of California ahead of Orions splashdown on December 11. As quickly as Orion splashes down, a team of divers, engineers, and professionals will leave the ship on small boats and arrive at the pill. When there, they will protect it and prepare to tow it into the back of the ship, understood as the well deck. The scuba divers will connect a cable to pull the spacecraft into the ship, called the winch line, and as much as four extra tending lines to attach points on the spacecraft. The winch will pull Orion into a specially developed cradle inside the ships well deck and the other lines will manage the movement of the spacecraft. As soon as Orion is positioned above the cradle assembly, the well deck will be drained pipes and Orion will be protected on the cradle.

” Last week, we finished our final practice session with the USS Portland, which will be our recovery ship for Artemis I,” said Melissa Jones, landing and recovery director, NASAs Kennedy Space Center. “We had an excellent three days working with them to fine-tune our procedures and integrate our groups so we can satisfy the objectives of recovering the Orion spacecraft.”
Orion has utilized approximately 8,050 pounds of propellant throughout Artemis I, which is 180 pounds less than anticipated prelaunch. There are 2,075 pounds of margin available over what was prepared for the objective, a 165-pound boost.
Since 5:29 p.m. CST on December 5, Orion was taking a trip 244,629 miles (393,692 km) from Earth and 16,581 miles (26,685 km) from the Moon, travelling at 668 miles per hour (1,075 km/h).
NASA Television and the agencys site will resume live coverage of Orions journey at 9 a.m. Tuesday.

NASAs Orion spacecraft is on course for its return to Earth on Sunday, December 11. On Flight Day 20 of the Artemis I objective, the spacecraft made its final and second close technique to the Moon at 10:43 a.m. CST Monday, December 5, simply prior to its return powered flyby burn, passing 80.6 miles (129.7 km) above the lunar surface.
The burn, which used the spacecrafts main engine on the European-built service module, lasted 3 minutes, 27 seconds, and altered the velocity of the spacecraft by about 655 mph (961 feet per second). It was the last significant engine maneuver of the flight test.
