In that way, the launch exercise was serving essentially as a real-time dress rehearsal that hopefully would conclude with an actual, successful liftoff.
For now, NASA officials said, plans call for keeping the 32-story-tall Space Launch System (SLS) rocket and its Orion astronaut capsule on its launch pad to avoid having to roll the massive spacecraft back into its assembly building for a more extensive round of tests and repairs.
If all goes as hoped, the SLS will blast off from the Kennedy Space Center in Cape Canaveral, Florida, on Saturday afternoon, during a two-hour launch window that opens at 2.17pm, sending the Orion on an uncrewed, six-week test flight around the moon and back.
The long-awaited voyage would kick off NASA’s moon-to-Mars Artemis program, the successor to the Apollo lunar project of the 1960s and ’70s before US human spaceflight efforts shifted to low-Earth orbit with space shuttles and the International Space Station.
