The astronauts are suited up and arrived at launch pad 39B for the Artemis II mission. NASA’s planned lunar fly-around by four astronauts would be the first moon trip in 53 years.
Waving to family, colleagues and news photographers, the crew boarded the so-called astrovan for the 9-mile ride to the launch pad and their awaiting SLS rocket.
NASA's launch team has loaded more than 700,000 gallons of fuel into the 32-story Space Launch System rocket early
Wednesday, setting the stage for the Artemis II mission.
The Space Launch System rocket is poised to blast off Wednesday evening with a two-hour launch window beginning at 6:24 p.m. EDT at Kennedy Space Center in Florida.
Artemis astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen will be on board. They’ll hurtle several thousand miles beyond the moon, hang a U-turn and then come straight back. No circling around the moon, no stopping for a moonwalk — just a quick out-and-back lasting less than 10 days. NASA promises more boot prints in the gray lunar dust, but not before a couple practice missions.
Unlike the Apollo missions that sent astronauts to the moonfrom 1968 through 1972, Artemis’ debut crew includes a woman, a person of color and a Canadian citizen.
Artemis II is the opening shot of NASA’s grand plans for a permanent moon base. The space program is aiming for a moon landing near the lunar south pole in 2028.
The Latest:
The Canadian fighter pilot and physicist is making his space debut and serving as his country’s first emissary to the moon.
“Maybe I’m naive, but I don’t feel a lot of personal pressure.”
Hansen, 50, grew up on a farm near London, Ontario, before moving to Ingersoll and pursuing a flying career.
He realizes only now how much effort it took to send men to the moon during Apollo.
“When I walk out and I look at the moon now, it looks and feels a little bit farther than it used to be,” he said.
Dangers still loom — something he’s shared with his college-aged son and twin daughters. “The most likely outcome is that we will come back safe. There’s a chance we won’t, and you will be able to move through life even if that happens,” he assured them.
The SLS rocket stands 322 feet (98 meters), shorter than the Apollo program’s Saturn V rocket. But it’s but more powerful at liftoff thanks to a pair of strap-on boosters.
Atop the rocket is the Orion capsule carrying the Artemis II crew.
The solid rocket boosters are bigger versions of the rocket motors on the space shuttles that carried up most of the parts of the International Space Station, as well as the astronaut construction crews.
The SLS uses the same fuel — liquid hydrogen — as the shuttle did.
Hydrogen leaks repeatedly grounded the shuttles as well as the SLS during testing in 2022 and again earlier this year, bumping Artemis II into April.
The last time Koch blasted into space, she was gone almost a year so she’s not sweating a quick trip to the moon and back.
The 47-year-old electrical engineer from Jacksonville, North Carolina, holds the record for the longest single spaceflight by a woman — 328 days. She took part in the first all-female spacewalk during her lengthy stay at the space station in 2019.
Before she got called up by NASA, Koch spent a year at a South Pole research station. Between that and her space stint, she feels she’s “inoculated” most of her family and friends.
“So far, I haven’t gotten too many nerves from folks. Maybe my dog, but I’ve reassured her that it’s only 10 days. It’s not going to be as long as last time.”
Her and her husband’s rescue pooch is named Sadie Lou.
As one of NASA’s few Black astronauts, Glover sees his presence on the mission as “a force for good.”
The 49-year-old Navy captain and former combat pilot from Pomona, California, makes it a habit to listen to Gil Scott-Heron’s “Whitey on the Moon” and Marvin Gaye’s “Make Me Wanna Holler” from the white-dominated Apollo era.
“I listen to those for perspective,” he said. “It captures what we did well, what we did poorly.”
The ability for him now to offer hope to others is “an amazing blessing and a privilege.”
He’s hyper-focused on running “our best race so that we can hand the baton off to the next leg” — a 2027 practice docking mission in orbit around Earth between an Orion crew capsule and one or two lunar landers.
Wiseman, Glover, Koch and Hansen have left the Neil Armstrong Operations and Checkout Building and are on their way to launch pad 39B.
Waving to family, colleagues and news photographers, the crew boarded the so-called astrovan for the 9-mile ride to the launch pad and their awaiting SLS rocket.
Before their highly anticipated walkout, commander Reid Wiseman and his crew played a quick card game with NASA’s chief astronaut Scott Tingle. It’s a preflight tradition since the space shuttle era.
Losing is good: It means the astronaut has gotten rid of all bad luck before launching.
The four thanked the suit techs and posed for photos, keeping a safe distance from many of the bystanders to avoid germs. They then went down the elevator at the Neil Armstrong Operations & Checkout Building and walk out to a barrage of cameras and cheers.
They’ll take a custom-designed astrovan for the ride to the launch pad
House Speaker Mike Johnson posted on the social media site X ahead of the planned Artemis II launch.
“Praying for the safety and success of the Artemis II crew and @NASA as they undertake a mission that will carry humanity farther into space than we have gone in over half a century. I had the privilege of hosting these courageous pioneers at the State of the Union earlier this year. Americans are watching proudly as our Golden Age reaches new heights!” Johnson wrote.
Wiseman, 50, a retired Navy captain from Baltimore, was serving as NASA’s chief astronaut when asked three years ago to lead humanity’s first lunar trip since 1972.
His wife Carroll’s death from cancer in 2020 gave him pause.
His two teenage daughters, especially the older one, had “zero interest” in him launching again after a 2014 trip to the International Space Station.
“We talked about it and I said, ’Look, of all the people on planet Earth right now, there are four people that are in a position to go fly around the moon,” he said. “I cannot say no to that opportunity.”
The next day, homemade moon cupcakes awaited him, along with his daughters’ support.
Artemis is the twin sister of Apollo in Greek mythology. They are the children of Zeus and Leto. Artemis has long been associated with the moon.
While the Artemis name builds on the Apollo program and pays homage to it, “there is no way we could be that same mission or ever hope to even be,” said NASA astronaut Christina Koch, part of the Artemis II crew.
The Apollo program was all about beating the Russians to the moon and planting the U.S. flag. NASA sent 24 astronauts to the moon between 1968 and 1972, including 12 moonwalkers. Now China is the competition.
NASA is striving for a long-term lunar presence under Artemis, with Mars to follow.
The Artemis II astronauts are now in their orange Orion spacesuits that they will wear for launch and reentry. Testing these new suits is one of the main goals of the mission.
The four are expected to emerge for their trip to the pad sometime before 2pm.
NASA created bright orange custom spacesuits for launch and reentry. Astronauts will also use them in case of a depressurization or some other emergency.
They can survive up to six days in the suits, inserting a straw into the helmet to sip water or protein shakes and relying on undergarment bags and bladders as a built-in toilet.
Future Artemis crews to the lunar surface will wear white moonwalking suits designed by Axiom Space.
During the Apollo era, astronauts wore the same white bulky spacesuits for launch and return as well as for moonwalks because there wasn’t enough storage on board for different outfits.
“We should have done Artemis 50 years ago,” said John Tribe, a propulsion engineer during the Apollo era.
The launch team has loaded more than 700,000 gallons of fuel into the 32-story Space Launch System rocket, setting the stage for the Artemis II crew to board.
The wind is picking up at Cape Canaveral, more clouds are appearing and rain is expected in about two hours. But there is no lightning threat, NASA says, and there’s still an 80% chance the weather will be good enough to launch.
L-minus tracks the overall time to liftoff, counting down the days, hours and minutes away before the planned blastoff. It doesn’t include built-in holds, or pauses — that’s T-minus time.
The T-minus countdown in the final 10 minutes is where nerves tense up and hearts start pounding. Automated software kicks off a series of highly choreographed milestones. During this period, the clock can be stopped if a problem is spotted and restarted if it’s fixed in time.
T-0 is the moment of liftoff — zero — when the boosters ignite and the rocket begins its journey.
NASA has a narrow time frame each month to fly to the moon.
The Earth and moon must be aligned just so to achieve the proper trajectory for the mission. In any given month, there’s only about a week when Artemis II astronauts can lift off.
The Orion capsule needs to get a check of its life-support and other systems in near-Earth orbit. If that goes well, Orion will fire its main engine to hurtle toward the moon, taking advantage of the moon and Earth’s gravity to get there and back in a slingshot maneuver that requires little if any fuel.
Orion also needs sunlight for power and can’t be in darkness for more than 90 minutes at a time. Plus NASA wants to minimize heating during reentry at flight’s end.
The latest launch window runs through April 6. The next opportunity opens on April 30.
The hydrogen tank of the rocket’s core stage is 100% filled. NASA said no significant leaks have been observed so far in fueling. It was hydrogen leaks that prevented the rocket from flying in February.
The alarm clocks just went off in Kennedy Space Center’s crew quarters.
That means it’s rise and shine for the three Americans and one Canadian who are about to become the first lunar visitors in more than 53 years.
They have a long day ahead of them, whether they launch or not.
After breakfast, they’ll start suiting up. NASA’s launch window opens at 6:24 p.m. and lasts a full two hours.
Launch director Charlie Blackwell-Thompson is wearing green as are many of the controllers alongside her in the firing room.
Green represents “go” for NASA, a color symbolizing good luck.
The team is monitoring the fueling of the 322-foot moon rocket, set to blast off Wednesday evening.
A plush toy named Rise will ride with the Artemis II astronauts around the moon, carrying the names of more than 5.6 million people.
Rise is what’s known as a zero gravity indicator, which gives the astronauts a visual cue of when they reach space.
The design was inspired by the iconic “Earthrise” photo during Apollo 8, showing the planet as a shadowed blue marble from space in 1968.
Rise was selected from more than 2,600 contest submissions. It was designed by Lucas Ye of California.
Commander Reid Wiseman and his crew tucked a small memory card into Rise before the toy was loaded into the Orion capsule. The card bears the names of all those who signed up with NASA to vicariously tag along on the nearly 10-day journey.
“Zipping that little pocket on the bottom of Rise was kind of the moment that put it all together for me,” Wiseman said. “We are going for all and by all. It’s time to fly.”
NASA is fueling the new rocket that will send four astronauts to the moon.
Launch teams have begun pumping more than 700,000 gallons (2.6 million liters) of liquid hydrogen and liquid oxygen into the Space Launch System rocket at Kennedy Space Center in Florida.
It’s the latest milestone in the two-day countdown that kicked off on Monday when launch controllers reported to duty.
It will take at least four hours to fully load the rocket before astronauts climb aboard for humanity’s first flight to the moon since Apollo 17 in 1972.
The two-hour launch window opens at 6:24 p.m. EDT.
