After three attempts to complete a critical fueling test of the Space Launch System rocket, NASA has decided to take a break.
On Saturday night the space agency announced plans to roll the large SLS rocket from the launch pad at Kennedy Space Center to the Vehicle Assembly Building in the coming days. This marks a notable step back for the program, which has tried since April 1 to complete a “wet dress rehearsal” test, during which the rocket is fueled and brought to within 10 seconds of launch.
The decision comes after three tries during the last two weeks. Each fueling attempt was scuttled by one or more technicals issue with the rocket, its mobile launch tower, or ground systems that supply propellants and gases.
