We knew it could happen because launching a rocket is a very complex thing. Yesterday afternoon, NASA, ESA and ULAlaunch confirmed the launch of Solar Orbiter will be delayed and adjusted to 7 Feb 23:15 EST (Florida Time) or 8 Feb 05:15 CET due to rescheduling of the Wet Dress Rehearsal. But there was also good news : the rocket accomplished its Wet Dress Rehearsal, a major milestone in preparation to launch Solar Orbiter.
For us, it means it will be all or nothing. 7 Feb is our last night in the USA to see the launch, let's hope everything goes well. Toi toi toi !!!!
