The Artemis II astronauts are already the champions of a fresh new era of lunar exploration. Now it's time to set a new distance record. Launched last week on humanity's first trip to the moon since 1972, the three Americans and one Canadian are chasing after Apollo 13's maximum range from Earth. That will make them our planet's farthest emissaries as they swing around the moon without stopping on Monday and then hightail it back home. Their roughly six-hour lunar flyby promises views of the moon's far side that were too dark or too difficult to see by the 24 Apollo astronauts who preceded them. A total solar eclipse also awaits them as the moon blocks the sun, exposing snippets of shimmering corona. "We'll get eyes on the moon, kind of map it out and then continue to go back in force," said flight director Judd Frieling. The goal is a moon base replete with landers, rovers, drones and habitats. A look at Artemis II's up-close and personal brush with another world - our constant ..
NASA cleared its moon rocket on Thursday for an April launch with four astronauts after completing the latest round of repairs. The 322-foot rocket will roll out of the hangar and back to the pad next week at Florida's Kennedy Space Center, leading to a launch attempt as early as April 1. It will mark humanity's first trip to the moon in more than 50 years. The Artemis II crew should have blasted off on a lunar flyaround earlier this year, but fuel leaks and other problems with the Space Launch System rocket interfered. Although NASA managed to plug the hydrogen fuel leaks at the pad in February, a helium-flow issue forced the space agency to return the rocket to the Vehicle Assembly Building for repairs, bumping the mission to April. The space agency has only a handful of days in early April to launch before standing down until April 30 into early May. Late last month NASA's new administrator, Jared Isaacman, announced a major overhaul of the Artemis programme. Dissatisfied wit
NASA's new moon rocket has suffered another setback, putting next month's planned launch with astronauts in jeopardy, the space agency announced Saturday. Officials revealed the latest problem just one day after targeting March 6 for humanity's first flight to the moon in more than half a century. Overnight, the flow of helium to the rocket's upper stage was interrupted, they noted. Solid helium flow is required for launch. NASA said it is reviewing all the data and preparing, if necessary, to return the Space Launch System rocket to the hangar for repairs at Florida's Kennedy Space Centre. It's possible the work could be done at the launch pad; the space agency said engineers are protecting for both options. "This will almost assuredly impact the March launch window," NASA said in a statement. Hydrogen fuel leaks had already delayed the Artemis II lunar fly-around by a month. A second fuelling test on Thursday revealed hardly any leaks, giving managers the confidence to aim for a
NASA took another crack at fuelling its giant moon rocket Thursday after leaks halted the initial dress rehearsal and delayed the first lunar trip by astronauts in more than half a century. For the second time this month, launch teams pumped more than 700,000 gallons (2.6 million liters) of supercold fuel into the rocket atop its launch pad. They counted all the way down to the half-minute mark as planned, then turned back the clocks to run through the final 10 minutes again. NASA completed the test late at night and said there was minimal hydrogen leakage, well within safety limits. It was the most critical and challenging part of the two-day practice countdown. Engineers were analysing the data, with the outcome determining whether a March launch is possible for the Artemis II moon mission with four astronauts. In a positive sign, the US-Canadian crew prepared to enter a two-week quarantine period Friday to provide what NASA called flexibility within the March launch window. Thre
The International Space Station returned to full strength with the arrival of four new astronauts to replace colleagues who bailed early because of health concerns. SpaceX delivered the US, French and Russian astronauts on Saturday, a day after launching them from Cape Canaveral. Last month's medical evacuation was NASA's first in 65 years of human spaceflight. One of four astronauts launched by SpaceX last summer suffered what officials described as a serious health issue, prompting their hasty return. That left only three crew members to keep the place running - one American and two Russians - prompting NASA to pause spacewalks and trim research. Moving in for eight to nine months are NASA's Jessica Meir and Jack Hathaway, France's Sophie Adenot and Russia's Andrei Fedyaev. Meir, a marine biologist, and Fedyaev, a former military pilot, have lived up there before. During her first station visit in 2019, Meir took part in the first all-female spacewalk. Adenot, a military helicopt
NASA ran into a leak while fueling its new moon rocket Monday in one final make-or-break test that will determine when astronauts can launch on a lunar fly-around. The launch team began loading the 322-foot (98-meter) rocket with super-cold hydrogen and oxygen at Kennedy Space Center at midday. More than 700,000 gallons (2.6 million liters) had to flow into the tanks and remain on board for several hours, mimicking the final stages of an actual countdown. But just a couple hours into the daylong operation, excessive hydrogen was detected near the bottom of the rocket. Hydrogen loading was temporarily halted, with just half of the core stage filled. The launch team scrambled to work around the problem using techniques developed during the only other Space Launch System rocket launch three years ago. That first test flight was plagued by hydrogen leaks before finally soaring. The crew, three Americans and one Canadian, monitored the critical dress rehearsal from nearly 1,000 miles ..
