According to the agency.
NASA’s Space Launch System (SLS) will return to launch pad 39B in early June to reattempt its wet dress rehearsal,
The SLS has seen a
handful of delays as a result of two failed wet dress rehearsal attempts, which included various hardware issues.
The moon rocket rolled out
to launch pad 39B in late March, but returned to the Vehicle Assembly Building (VAB) on April 26, because of a faulty upper stage check valve and a small leak.
“Engineers successfully completed
work on a number of items observed during the previous wet dress rehearsal test,” NASA’s statement read.
The rocket also
encountered a temperature limit issue, which paused the first rehearsal attempt for several hours.
The rocket’s propellant
, liquid oxygen, must be maintained at minus 297 degrees Fahrenheit.
