NASA Orion Spacecraft Completes Lunar Flyby – Clarksville Online

By November 22, 2022Sports events

washington d.c. – NASA’s Orion spacecraft picked up the signal with the deep space network, at 6:59h VSJ after successfully completing the outgoing powered flyby at 6:44 CT with a shot from the orbital maneuvering system engine for 2 minutes and 30 seconds to accelerate the spacecraft to a rate of over 580 mph.

At the time of the burn, Orion was 328 miles above the Moon, traveling at 5,023 mph. Shortly after the burn, Orion passed 81 miles above the Moon, traveling at 5,102 mph. At the time of the lunar flyby, Orion was over 230,000 miles from Earth.

The exiting powered hover is the first of two maneuvers required to enter the far retrograde orbit around the Moon. The spacecraft will perform the remote retrograde orbit insertion burn on Friday, Nov. 25, using the European Service Module.

Orion will stay in this orbit for about a week to test the spacecraft systems. The distant retrograde will take Orion 40,000 miles beyond the Moon before returning to Earth. Orion’s greatest distance from Earth will be Monday, Nov. 28 at 3:05 p.m. CT at over 268,500 miles. Orion’s greatest distance to the Moon will be Friday, November 25 at 3:53 p.m. CT at over 57,250 miles.

The Deep Space Network, operated by NASA’s Jet Propulsion Laboratory in Southern California, manages Artemis I’s communications beyond low Earth orbit. This includes mission path corrections, powered hover burns, and remote retrograde orbit insertion and departure, while the near space array provides additional navigation data with the help of the Near Space Network’s constellation of tracking and data relay satellites.

The Deep Space Network consists of three facilities equidistant from each other –? about 120 degrees longitude distance?- around the world. These sites are at?gold stone, near Barstow, Calif.; near?Madrid, Spain; and nearby?Canberra, Australia.

The strategic location of these sites allows for constant communication with spacecraft as our planet rotates – before a distant spacecraft sinks below the horizon at one site, another site can pick up the signal and continue to communicate. Orion first regained the signal with the Madrid ground station after the lunar flyby, then the transition signal to the gold stone station.

NASA television coverage of the insertion burn in remote retrograde orbit will begin at 3:30 p.m. CT Friday, with the burn scheduled to take place at 3:52 p.m.
