Orion’s homecoming got here 50 years to the day after the Apollo 17 spacecraft touchdown on the lunar floor in 1972 on the Taurus-Littrow valley, the final human mission to the moon. And it heralded, the area company mentioned, a sequence of upcoming missions which can be to be piloted by a brand new era of NASA astronauts as a part of the Artemis program.
The flight was delayed repeatedly by technical issues with the large Space Launch System rocket and the spacecraft. But the 26-day, 1.4 million-mile mission went “exceedingly well,” NASA officers mentioned, from the launch on Nov. 16 to flybys that introduced Orion inside about 80 miles of the lunar floor and instantly over the Apollo 11 touchdown website at Tranquility Base.
“From Tranquility Base to Taurus-Littrow to the tranquil waters of the Pacific, the latest chapter of NASA’s journey to the moon comes to a close. Orion, back on Earth,” NASA’s Rob Navias mentioned through the company’s dwell broadcast of the occasion.
NASA Administrator Bill Nelson mentioned it was “historic because we are now going back to space, to deep space, with a new generation.” The profitable mission augurs a brand new period, he added, “one that marks new technology, a whole new breed of astronauts, and a vision of the future.”
“This is what mission success looks like, folks,” mentioned Mike Sarafin, NASA’s Artemis I mission supervisor, at a day information convention. “This was a challenging mission. … We now have a foundational deep space transportation system. And while we haven’t looked at all the data that we’ve acquired, we will do that over the coming days and weeks.”
Now that the spacecraft is safely dwelling, NASA will instantly start to evaluate the info gathered on the flight and put together for the Artemis II mission — which might put a crew of astronauts on the spacecraft for one more journey in orbit across the moon. NASA hopes that mission would come as early as 2024, with a lunar touchdown to return as early as 2025 or 2026. That could be the primary time folks stroll on the moon because the final of the Apollo missions.
NASA has but to call the crews assigned to these flights — that might are available early 2023, Vanessa Wyche, the director of NASA’s Johnson Space Center mentioned. But its astronaut corps has already shifted its coaching to concentrate on Orion and lunar flights, after spending a long time focusing solely on missions to the International Space Station.
One of essentially the most important exams for the Orion spacecraft got here Sunday morning when it hit Earth’s environment touring at practically 25,000 mph, 32 instances the pace of sound. The friction generated excessive temperatures — 5,000 levels Fahrenheit — that pressured the capsule’s warmth defend. A sequence of parachutes then deployed, delivering the spacecraft to the ocean at underneath 20 mph, the place a Navy restoration ship, the USS Portland, and a number of other small boats and helicopters had been ready to greet it.
Nelson mentioned the warmth defend carried out “beautifully,” and Navias mentioned the touchdown was “textbook.”
The profitable mission offers NASA some momentum after years of stagnation in its human spaceflight program. After it retired the area shuttle fleet in 2011, NASA was compelled to depend on Russia to ship its astronauts to the area station. SpaceX lastly began human spaceflight missions for NASA in 2020, and Boeing, the opposite firm contracted for flights to the ISS, hopes to ship its first crew there subsequent yr.
But now, for the primary time in a long time, NASA has one other vacation spot for its astronauts — the moon — and a program, Artemis, that has survived subsequent presidential administrations, to get them there.
The program, which vows to land the primary lady and particular person of coloration on the moon, was born underneath the Trump administration and carried on by the Biden White House. That continuity stands in stark distinction to a long time of presidential administrations pointing NASA’s human area exploration directorate to totally different objectives within the photo voltaic system, from the moon, to Mars, an asteroid, and again to the moon once more.
The query now could be: Can NASA preserve this system’s momentum and preserve Congress funding it? Support for spaceflight applications may be fickle — even the Apollo missions rapidly started to lose assist from Congress and the general public’s curiosity. And whereas NASA is likely to be celebrating the Artemis I as a triumph immediately, that enthusiasm may simply fade by the point Artemis II is able to fly in 2024.
In the post-flight information convention, Nelson, a former U.S. Senator from Florida, mentioned he’s assured the joy would proceed to construct with the general public, significantly as NASA names the crew for the subsequent mission. Congress can be invested in this system, he mentioned. “I am not worried about the support from the Congress,” he mentioned. “That support is enduring.”
While that is still to be seen, NASA was celebrating step one towards returning astronauts to the moon and fulfilling the pledge of Eugene Cernan, the final man to stroll on the moon, who vowed, as he departed the moon for Earth, “We shall return.”
Robert Cabana, NASA’s affiliate administrator and a former astronaut, mentioned that he wished Cernan “were alive and could have seen this mission. It would have meant a lot to him.”
