    Live coverage: Artemis 1 moon rocket to return to hangar as hurricane threatens Florida

    NASA has decided to roll the SLS moon rocket back to the Vehicle Assembly Building as Florida continues to be threatened by Hurricane Ian.

  • NASA completes cryogenic tanking test on Artemis 1 moon rocket

    Engineers filled up the Artemis 1 moon rocket with more than 750,000 gallons of super-cold propellants in a tanking test Wednesday at Kennedy Space Center after successfully troubleshooting another hydrogen leak. NASA's launch director said she was "extremely encouraged" by the test, but officials have not yet committed to another attempt to launch the uncrewed test flight to the moon at the next opportunity Sept. 27.

  • NASA astronaut launches to space station aboard Russian rocket

    Despite severely strained U.S.-Russian foreign relations, an American astronaut joined two Russian cosmonauts aboard a Soyuz spacecraft in Kazakhstan and rocketed into orbit Wednesday on a two-orbit flight to the International Space Station.

    Live coverage: NASA fully loads Artemis 1 moon rocket in cryogenic test

    NASA's launch team says they got a hydrogen leak under control in a fueling line near the bottom of the Artemis 1 moon rocket's core stage, allowing engineers to continue with a cryogenic tanking test on pad 39B at Kennedy Space Center on Wednesday. The leak temporarily halted operations to load more than 750,000 gallons of super-cold liquid hydrogen and liquid oxygen into the Space Launch System.

  • NASA preps for SLS fueling test Wednesday

    Engineers are ready to reload NASA's Artemis moon rocket with supercold fuel Wednesday to make sure a repaired liquid hydrogen quick-disconnect fitting is leak free, one of two requirements that must be met before the agency can make a third attempt to launch the huge booster September 27 on the program's maiden moonshot.

  • NASA delays SLS tanking test, next launch opportunity

    NASA said Monday it is now targeting Wednesday, Sept. 21, for a critical fueling test on the Space Launch System moon rocket, which could allow for another attempt to launch the unpiloted Artemis 1 lunar test flight as soon as Sept. 27, assuming engineers find no problems and the Space Force approves an extension for the rocket's range safety system. The updated schedule is a four-day delay for the SLS tanking test and next launch opportunity.

  • NASA officials evaluating late September launch dates for Artemis 1 moon mission

    NASA officials said Thursday they hope to try again to launch the Artemis 1 moon rocket from the Kennedy Space Center as soon as Sept. 23 or 27, but that schedule comes with two big caveats: A repair to a leaky liquid hydrogen fueling line must hold tight during a tanking test next weekend, and the Space Force's Eastern Range has to extend the certification of batteries on the moon rocket's flight safety system.

  • Hydrogen leak delays moonshot by at least several weeks

    NASA's star-crossed Space Launch System moon rocket was grounded for the second time in five days Saturday, this time by a large hydrogen leak in a fuel line quick-disconnect fitting that will delay the $4.1 billion booster's maiden flight by several weeks, likely into October.

    Live coverage: NASA to conduct Artemis 1 repair work at the launch pad

    NASA says it will carry out repairs and tests on the Artemis 1 rocket at the launch pad rather than immediately rolling back to the hangar. The agency needs the Space Force to extend the certification of flight termination batteries if it wants to make another launch attempt in September. Otherwise the rocket will have to return to the assembly building and face a lengthy delay.

  • Lunar demo mission to provide ‘stress test’ for NASA’s Artemis moon program

    The first unpiloted mission for NASA's Artemis lunar program aims to prove out the most powerful rocket to ever launch from U.S. soil, and test the function of a human-rated spacecraft traveling more than 40,000 miles beyond the far side of the moon before blazing back through Earth's atmosphere at nearly 25,000 mph.
