Off to a flying start

Now that we have the Sentinel-1B safely in the ‘high bay’ at Europe’s Spaceport near Kourou in French Guiana, or Centre Spatial Guyanais, CGS, as it’s known locally, the campaign to prepare the satellite for liftoff on...

Sentinel-1B launch campaign starts

With Sentinel-1A now in orbit around Earth since April 2014, it is time for its identical sister satellite, Sentinel-1B, to make up the two-satellite constellation. The pair of satellites will orbit 180° apart to optimise revisit times...

A night shift like never before

One might think One might think that after being able to bring the launch date forward from 15 to 3 April (since when do launch dates come forward?), that after successfully achieving the shortest launch campaign in...
