NASA’s Artemis I Orion capsule has now traveled farther past Earth than any spacecraft designed to hold astronauts.
The uncrewed Orion flew past the record-setting distance (opens in new tab) achieved by the Apollo 13 command module “Odyssey” at 248,655 miles from Earth (216,075 nautical miles or 400,171 kilometers) at about 8:40 a.m. EST (1340 GMT) on Saturday (Nov. 26).
The Apollo 13 spacecraft had beforehand set the document on April 14, 1970, at 7:21 p.m. EST (0021 GMT on April 15).
“It did not register [with] me then. We have been so busy with our heads down that we simply did not have time to consider it,” Gerry Griffin, former flight director who helped lead Mission Management throughout the Apollo 13 mission, mentioned in a NASA-led Twitter Spaces panel discussion (opens in new tab) on Tuesday (Nov. 12). “The truth is, till nearly a 12 months in the past, I had no thought we had gone the farthest from Earth on Apollo 13. I figured we would executed it on another mission.”

The unique flight plan for Apollo 13 didn’t have the spacecraft touring so far-off. As is now broadly recognized (having been depicted in a 1995 Hollywood film), the mission out of the blue switched from focusing on a moon touchdown to securely bringing the astronauts again to Earth after a mid-flight explosion tore via the automobile’s service module.
Apollo 13 reached the gap it did as a result of there was an emergency want to make use of the moon’s gravity to slingshot the spacecraft again to Earth as shortly and as safely as attainable.
Equally, the Artemis I flight profile was not designed particularly to interrupt the Apollo 13 document. It solely did so as a result of NASA despatched the Orion right into a lunar distant retrograde orbit.
“Artemis I used to be designed to emphasize the techniques of Orion and we settled on the distant retrograde orbit as a really great way to do this,” mentioned Jim Geffre, NASA’s Orion spacecraft integration supervisor. “It simply so occurred that with that basically massive orbit, excessive altitude above the moon, we have been capable of go the Apollo 13 document. However what was extra necessary although, was pushing the boundaries of exploration and sending spacecraft farther than we had ever executed earlier than.”
Orion didn’t cease on the Apollo 13 distance. NASA expects the Artemis I capsule to achieve a most distance from Earth of 268,553 miles (432,194 km) at 4:06 p.m. EST (2106 GMT) on Monday (Nov. 28). From there it is going to proceed touring midway across the moon till firing its orbital maneuvering system engine (opens in new tab) to go away the distant retrograde orbit, establishing its second close pass to the lunar surface (opens in new tab) on Dec. 5, adopted by its return to Earth on Dec. 11.

The Apollo 13 document just isn’t the one connection Artemis I has to the 1970 mission.
Though Orion doesn’t have a crew, it’s flying instrumented manikins to measure radiation publicity and the stresses a crew member would expertise on a flight to the moon and again. One of many stand-ins, the only-full physique instance, was named “Commander Moonikin Campos” (opens in new tab) after the late Arturo Campos, who throughout the Apollo 13 mission wrote the emergency procedures to switch energy from the Apollo lunar module batteries to the command module, enabling Odyssey to have sufficient electrical energy to reach a safe splashdown (opens in new tab).
Campos, who died in 2004, was {the electrical} energy subsystem supervisor for the lunar module, and his colleagues within the Mission Analysis Room and Mission Operations Management Room have been awarded the Presidential Medal of Freedom for his or her efforts.
As “Moonikin Campos” just isn’t an actual particular person, the Apollo 13 astronauts (opens in new tab) — James Lovell, Fred Haise and Jack Swigert — nonetheless hold the Guinness World Record (opens in new tab) for the “farthest distance from Earth reached by people” at 248,655 miles (400,171 km). That will change although when NASA launches its subsequent Artemis mission — the primary to hold astronauts — tentatively slated for 2024.
“We might or might not break Apollo 13’s human spaceflight distance document, however will not know till after we launch,” Laura Rochon, a NASA’s public affairs specialist, advised collectSPACE.com. “Artemis II is a excessive Earth orbit, adopted by a free return flyby of the moon. The Earth to moon distance is anyplace from 221,500 miles at perigee to 252,700 at apogee [356,500 to 407,700 km]; flyby altitudes vary from about 4,000 to 12,000 miles [6,400 to 19,000 km] on the far side of the moon, so the total may very well be anyplace from round 225,500 to 265,000 miles [363,000 to 426,500 km] relying on launch date.”
There’s a NASA spacecraft that when carried a crew and has since traveled effectively past the Apollo 13 distance from Earth, having entered a heliocentric orbit. The Apollo 10 lunar module (“Snoopy (opens in new tab)“) ascent stage can be the document holder right now if it had been designed to hold people to the Solar and its placement right into a disposal orbit had not been after its use by the Apollo 10 crew was over, in line with NASA.
