Nasa aims to make a second attempt to launch its giant next-generation moon rocket on Saturday, Sept. 3, five days after a pair of technical issues foiled an initial try at getting the spacecraft off the ground for the first time, agency officials said on Tuesday.
But prospects for success on Saturday appeared clouded by weather reports predicting just a 40% chance of favorable conditions that day, while the U.S. space agency acknowledged some outstanding technical issues remain to be solved.
At a media briefing a day after Monday’s first countdown ended with the flight scrubbed, Nasa officials said Monday’s experience was useful in trouble-shooting some problems and that additional difficulties could be worked through in the midst of a second launch try.
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 2:17 p.
