The rocket received’t go away the bottom, however the rocket’s techniques are all powered on and this rehearsal checks that every little thing is prepared for when it does truly launch.
The primary check was scheduled for final weekend on Sunday, April 3, and went forward regardless of climate together with lightning that struck the towers across the rocket.

Nevertheless, now it says the rehearsal will go forward subsequent week and there will likely be some adjustments to the deliberate check. “NASA is planning to proceed with a modified moist costume rehearsal, primarily targeted on tanking the core stage, and minimal propellant operations on the interim cryogenic propulsion stage (ICPS) with the bottom techniques at Kennedy,” the company wrote in an replace. “Because of the adjustments in loading procedures required for the modified check, moist costume rehearsal testing is slated to renew with name to stations on Tuesday, April 12 and tanking on Thursday, April 14.”
NASA additionally shared that engineers have recognized a helium examine valve that isn’t working. The small piece of {hardware}, a couple of inches lengthy, works by solely letting helium circulation in a single route for security causes. It says it can share extra particulars concerning the concern and the brand new check plan subsequent week on Monday, April 11.
