The European Space Agency (ESA) is hoping to finally gets its Sentinel-1B Earth-watching satellite off the ground tonight, following three cancelled launches.
Sentinel-1B was scheduled to depart the launchpad at Kourou, French Guiana, atop a Soyuz lifter on Friday. Unfavourable weather scuppered the attempt.
ESA says the offending unit has been replaced, and pending a technical review, Sentinel-1B will be on its way tonight at 21:02 GMT. The agency will have live coverage here.
