NASA Artemis Moon Mission Completes Flyby With Orion Spacecraft - The New York Times

Science|NASA Spacecraft Finishes Its Close Encounter With the Moon

NASA’s Orion spacecraft zipped past the moon’s acold broadside connected Monday, passing wrong 81 miles of the surface.

The spacecraft, which has nary humans connected board, has been traveling toward the satellite since Wednesday, erstwhile it launched arsenic portion of the Artemis I mission. Its travel volition past 20 much days.

“The conveyance continues to run exceptionally,” Howard Hu, the Orion programme manager astatine NASA, said during a quality league connected Monday evening.

One of the mission’s main purposes is to verify that the Orion spacecraft works arsenic designed, and to let NASA to marque immoderate indispensable adjustments and fixes earlier astronauts committee for the Artemis II mission, which volition not instrumentality disconnected until astatine slightest 2024. The 3rd Artemis mission, involving the Orion spacecraft arsenic good arsenic a SpaceX vehicle, volition purpose to onshore astronauts connected the moon’s surface.

A fewer minutes earlier Orion’s closest walk with the satellite connected Monday, the capsule fired its motor for 2.5 minutes. That accelerated its velocity arsenic the spacecraft swung outward toward what is known arsenic a distant retrograde orbit.

The orbit is distant — 40,000 miles supra the lunar surface; retrograde means that the spacecraft is traveling astir the satellite successful the absorption other to the mode the satellite travels astir the Earth.

The spacecraft volition beryllium determination for six days, providing an extended play of clip for ngo controllers to trial retired Orion’s systems. NASA pointed retired that it would beryllium the farthest that immoderate spacecraft designed to transportation humans had ever been from Earth. (The erstwhile grounds occurred during Apollo 13 erstwhile the crippled spacecraft had to plaything astir the moon for the travel backmost to Earth alternatively of entering orbit.)

With Orion down the moon, NASA’s ngo controllers mislaid interaction with the spacecraft, arsenic planned. Thus, they did not cognize that the motor firing had succeeded until Orion emerged again 34 minutes later.

The spacecraft demonstrated its quality to nonstop unrecorded video backmost to Earth during the flyby, said Judd Frieling, a NASA formation director, who added it would transmit much connected a NASA website erstwhile possible. The Orion besides took video and images of the moon’s acold broadside portion it was retired of interaction down the moon.

“It volition instrumentality america a fewer days to get those peculiar images down,” Mr. Frieling said.

Artemis I lifted disconnected connected Wednesday connected apical of NASA’s large caller Space Launch System rocket from the Kennedy Space Center successful Florida.

Except for insignificant glitches — Mike Sarafin, the Artemis ngo manager, called them “funnies” — the Artemis I formation has proceeded smoothly. The funnies included Orion’s prima trackers being momentarily confused erstwhile the spacecraft’s thrusters fired.

“We are connected formation time six of a 26-day mission,” Mr. Sarafin said connected Monday, “so I would springiness it a cautiously optimistic A+.”

The flyby exercised the large portion of Artemis that is not American. The parts of the Space Launch rocket were built by Boeing, Northrop Grumman and the United Launch Alliance portion the Orion capsule itself was built by Lockheed Martin.

However, the work module — the portion of Orion beneath the capsule that houses the thrusters, star arrays, communications instrumentality and different supplies — was built by Airbus, and was 1 of the contributions by the European Space Agency to the Artemis program. The module volition not instrumentality to Earth, but alternatively volition beryllium jettisoned to pain up successful the ambiance soon earlier the capsule splashes down.
