Pitcher has confirmed that Orion shipminutes after disconnection due to its position behind Moonhas resumed signal with its deep space network At 7:59 am, followed by successfully firing the Orbital Maneuvering System engine at 7:44 am to accelerate the spacecraft to a speed of over 933 km/h.

At the time of power-up, Orion was 527 km above the Moon, traveling at over 8,000 km/h. Soon after, it passed 130 km above the Moon, traveling at a speed of 8,210 km/h. At the time of the lunar flyby, the spacecraft was more than 370,149 km away from Earth.

This departure is the first of two maneuvers required to enter flight. distant retrograde orbit around our satellite. The Artemis mission spacecraft, which lifted off on November 16, will perform its insertion burn into this orbit on Friday, November 25, using the European Service Module provided by ESA.

Orion will remain in that orbit for about a week to test the spacecraft’s systems. A distant retrograde orbit will take Orion 64,373 km from the Moon before returning to Earth. Orion’s greatest distance with respect to Earth will be more than 432,108 km on Monday, November 28, and more than 92,134 km with respect to our satellite on Friday, November 25.

Deep Space Network, managed by NASA Jet Propulsion Laboratory In Southern California, it handles Artemis I communications beyond low-Earth orbit.

This includes mission trajectory corrections, powered approach flights and remote retrograde orbit entry and departure, while the Near Space Network provides supplementary navigation data with the help of its constellation of tracking satellites and data transmission.

Orion took this high-resolution selfie in space from its wing-mounted camera of solar panels during the spacecraft’s routine external inspection on the third day of the Artemis I mission.

NASA Deep Space Network

The Deep Space Network consists of three bases around the world equidistant from each other (with a difference of about 120 degrees in longitude). These facilities are located in Goldstone (near Barstow, California in the US), Robledo de Chavela (near Madrid, in Spain) and Canberra (Australia).

The strategic location of these sites allows for continuous communication with spacecraft as our planet rotates. Before a remote spacecraft sinks below the horizon at one location, the other can receive the signal and continue to communicate.

Orion initially retrieved the signal with the Madrid ground station after the lunar flyby, and then it went to the Goldstone station in California.
