CAPE CANAVERAL, Fla. — NASA’s new period of deep space exploration has begun.
With a mighty roar, essentially the most highly effective NASA rocket ever constructed — the Space Launch System (SLS) — soared into the Florida early morning sky on the Artemis 1 mission, a dangerous and long-delayed check flight to ship a next-generation space capsule to the moon and again. Liftoff occurred at the moment (Nov. 16) at 1:47 a.m. EST (0647 GMT) from NASA’s Pad 39B right here at Kennedy Area Heart (KSC) in Florida.
Artemis 1 is sending NASA’s new Orion spacecraft on an uncrewed check flight across the moon. This shakedown mission, NASA’s first flight of a crew-capable moon ship in practically 50 years, serves because the proving floor to see if SLS and Orion are prepared to assist return astronauts to the lunar floor by 2025 below NASA’s Artemis program.
“Liftoff of Artemis 1!” NASA commentator Derrol Nail stated throughout the webcast of this morning’s launch. “We rise collectively, again to the moon and past.”
A couple of minutes later, Artemis launch director Charlie Blackwell-Thompson addressed her workforce at mission management.
“That is your second,” she stated. “We’re all a part of one thing extremely particular: The primary launch of Artemis, step one in returning our nation to the moon and on to Mars. What you’ve got accomplished at the moment will encourage generations to return.”

As in earlier makes an attempt, this morning’s attempt noticed its share of setbacks. Whereas the SLS higher stage fueling course of was underway roughly three hours previous to launch, an intermittent leak was detected within the liquid hydrogen replenishment valve on Artemis 1’s cell launch tower. NASA despatched a specialised “Pink Crew” to the tower to tighten packing nuts to cease the leak, a course of that took roughly an hour.
Following that repair, a separate concern with an ethernet change at a radar website on the U.S. Area Power Japanese Vary brought on additional uncertainty, prompting a “no-go” on the vary till a substitute was discovered. The ethernet concern was mounted whereas the launch countdown was on the deliberate T-10 minutes maintain.
This was the third launch try for Artemis 1. An preliminary try on Aug. 29 was scrubbed as a consequence of a glitch in the cooling process that one of many rocket’s 4 essential engines skilled. A second try on Sept. 3 was additionally scrubbed when a hydrogen leak was detected throughout the rocket’s prolonged fueling course of. SLS was then rolled again to KSC’s Automobile Meeting Constructing for repairs and to shelter it from Hurricane Ian, which slammed into Florida’s Area Coast in late September.
Most not too long ago, the amended goal date of Nov. 12 was delayed to at the moment due to Hurricane Nicole (which was rapidly downgraded to a tropical storm following landfall). Excessive winds produced by the storm tore a piece of insulative caulking away from the skin of the Orion spacecraft, prompting Artemis mission groups to check the problem and decide if a Nov. 16 launch was inside security parameters.
Groups right here at KSC quickly assessed the harm within the days following the storm and reached the conclusion that SLS and Orion had been nonetheless good for this morning’s launch. “I really feel good headed into this try on the sixteenth,” Mike Sarafin, Artemis mission supervisor at NASA headquarters in Washington, stated throughout a press briefing on Sunday night (Nov. 13).
Jeremy Parsons, deputy supervisor of NASA’s Exploration Floor Techniques program at KSC, stated throughout a teleconference on Monday (Nov. 14) that the work the Artemis mission workforce has carried out with a purpose to get SLS off the bottom following the storm has been unbelievable. “Should you had been to ask me a few weeks in the past, would we undergo a storm like Hurricane Nicole after which be capable of flip round and have cleared the car and be in fine condition, I might have stated, hey, likelihood is in all probability low. However this workforce has actually simply been firing on all cylinders,” Parsons stated.
Eight minutes after liftoff this morning, the SLS rocket’s higher stage reached orbit with Orion, with the spacecraft beginning to unfurl its 4 solar arrays from its service module shortly thereafter. A spacesuit-clad Snoopy plush toy is aboard to drift round in weightlesness along with a Shaun the Sheep doll from NASA’s Orion accomplice the European Area Company, which offered the service module.
If all goes nicely, the SLS higher stage ought to hearth its single engine to boost its orbit just below an hour after launch, then hearth up once more 98 minutes after liftoff to place Orion on the right track for the moon. Whereas NASA hopes for achievement, Artemis 1’s check flight nature means one thing may all the time go fallacious.
“It’s a new creation. It’s a new rocket and a brand new spacecraft,” NASA’s Artemis 1 mission supervisor Mike Sarafin stated earlier than launch. “That is one thing that has not been accomplished in over 50 years and is extremely troublesome.”
NASA engineers could also be on pins and needles for the mission, however Artemis 1 seems to have captured the general public’s creativeness.

A dangerous check flight, with science, too
At its core, the Artemis 1 mission goals to indicate that the SLS rocket and Orion are able to fly astronauts to the moon as a part of a sustained program of lunar exploration that can finally allow crewed flights to Mars. NASA desires to make use of the automobiles to construct a Gateway space station across the moon, then ship crews there to make use of it as a house base for journeys to the lunar south pole and different unexplored realms.
NASA has stated that Artemis 1’s objectives are easy, however laborious. A giant precedence is to indicate that Orion’s warmth defend can survive the scorching-hot reentry temperatures (as much as 5,000 levels Fahrenheit, or 2,800 levels Celsius) attributable to returning residence from the moon at 25,000 mph (40,000 kph). NASA additionally desires Orion to display that it is able to preserve astronauts alive in lunar orbit. And the company goals to efficiently get better the capsule so it may be studied forward of Artemis 2, this system’s first crewed flight across the moon, which is slated to fly in 2024.
“This primary mission is our first check of our deep space transportation methods earlier than we put crew on them,” Jim Free, NASA’s affiliate administrator for exploration methods improvement, stated earlier than liftoff. “It’s foundational in that sense. We have to be taught concerning the automobiles earlier than we put crew on them.”
Orion ought to attain the moon round Nov. 22, when it is going to method inside 60 miles (96.6 km) throughout a flyby towards its last orbit. That path, referred to as a “distant retrograde orbit,” will take Orion on a protracted, looping route that extends 40,000 miles (64,000 km) past the moon at its farthest level, setting a brand new distance file for a crew-capable ship. Orion hits that milestone round day 10 and can spend two weeks in orbit earlier than making ready for the journey residence. The spacecraft will return to Earth on Dec. 11 with a splashdown within the Pacific Ocean off the coast of California.
There are science experiments aboard the Artemis 1 mission, too. Aboard the SLS rocket, 10 cubesats launched with Artemis 1 and will probably be deployed on the best way to the moon. Their missions range extensively, with some destined to orbit the moon and hunt down traces of water ice whereas others will check exploration applied sciences. One, referred to as NEA Scout, will use a solar sail to go to a tiny asteroid.
Inside Orion is a “Moonikin” manikin named Commander Campos, which is carrying a brand new, vivid orange launch and entry swimsuit NASA has designed for future astronauts. Two limbless manikins, nicknamed Helga and Zohar, will check a novel vest called AstroRad designed to guard astronauts from the dangerous radiation of deep space. Nonetheless extra experiments, like NASA’s Organic Experiment 1, will develop yeast, fungi and extra inside Orion to see how the deep space surroundings impacts genes and DNA.

From Apollo’s legacy, Artemis to the moon
NASA’s Artemis program is called for the dual sister of Apollo and goals to land the primary girl and first particular person of coloration on the moon throughout its first lunar touchdown on the Artemis 3 mission no sooner than 2025.
The SLS rockets and Orion spacecraft are a wierd mix of space historical past and future promise. Artemis 1 launched from the identical pad utilized by NASA’s Apollo 10 mission in 1969, which despatched three astronauts across the moon months earlier than the primary astronaut touchdown on Apollo 11. (NASA invited Apollo 10 commander Tom Stafford to at the moment’s launch.) The SLS rocket is powered by legacy space shuttle engines and stable rocket booster segments.
The 322-foot-tall (98 meters) SLS rocket is barely shorter than the large Saturn V rockets of Apollo, however the brand new car is extra highly effective, producing 8.8 million kilos of thrust at liftoff, most of it from its stable rocket boosters.
The Orion spacecraft, too, has developments. It is 30% bigger than an Apollo capsule and is designed to hold 4 astronauts, in comparison with Apollo’s three. Its 16.5-foot-wide (5 m) warmth defend is the largest of its type but to fly in space. Its service module, which offers its energy and propulsion, is constructed by Airbus and offered by the European Space Agency, which in flip will fly European astronauts on future Artemis flights.
To succeed in the moon, NASA has tapped non-public firms like SpaceX, Northrop Grumman, Maxar and extra to construct the crewed lunar landers, Gateway space station habitats and different parts for Artemis. That mannequin, which itself relies on NASA’s industrial space efforts on the Worldwide Area Station, will function a template for missions to Mars, too, NASA Administrator Invoice Nelson stated. Admittedly, he added, a NASA crewed flight to Mars is not possible till no less than the late 2030s.
“Our DNA, as an American individuals now joined by our worldwide companions, is to discover,” Nelson informed Area.com of the Artemis program’s aim. “We constructed this nation with a frontier, and that frontier is upward.”
