Separation of Sentinel-1B

It has been four difficult days due to three launch aborts: two delays due to bad weather conditions and one because of an anomaly on the Soyuz rocket.  Finally Sentinel-1B has been placed into orbit. After months...

Sentinel-1B liftoff rescheduled for today

The technical anomaly with the launch that halted liftoff yesterday has been resolved. The aim is to launch today, 25 April at 23:02 CEST (21:02 GMT). The launch will be streamed live from Europe's Spaceport in French...

Sentinel-1B launch delayed due to anomaly

Following an anomaly observed during the countdown for the launch of Soyuz flight VS14 carrying Sentinel-1B, the countdown was halted. The launch vehicle and satellites have been switched into a completely safe standby mode. The new launch...

Our Soyuz gets a drink!

Just a few minutes ago, and following a GREEN weather report from Kourou, teams from Arianespace and CNES began fuelling the Soyuz rocket that will loft Sentinel-1B into orbit this evening. Arianespace have just issued this note:...

From encapsulation to roll out

Video showing the final steps before Sentinel-1B was rolled out to the launch pad. The Soyuz rocket also carries three CubeSats developed by teams of university students through the ESA's Eductation ‘Fly Your Satellite!’ programme.

PDGS is GO for launch

The Sentinel-1 Payload Data Ground Segment (PDGS) team had a pre-launch meeting at ESA's centre for Earth observation (ESRIN) on 15 April. During the briefing, each team member confirmed the status of their specific system or area...

On the pad

Yesterday, the team witnessed the roll out of the Soyuz launcher to the launch pad at Europe’s spaceport here in Kourou, French Guiana. It was an early start. Operations began with moving the mobile gantry away from...

Sentinel-1B joins Fregat. (ESA–Manuel Pedoussaut, 2016)

On Fregat upper stage and encapsulated

Last Friday, we had to say good-bye to our satellites as they were sealed from view within the Soyuz rocket fairing. The encapsulation process followed another critical milestone, that of mating the Sentinel-1B to the Fregat upper...

Piggyback missions integrated on launcher upper stage

The Soyuz rocket that is being used to launch Sentinel-1B will also carry other missions into orbit. Three CubeSats are taking advantage of the lift into space. These small satellites, each measuring just 10×10×10 cm, have been...

Fully fuelled and under pressure

Following the successful completion of the fuelling operation, the team continued with the next hazardous step: pressurizing the fuel tanks. This last step was completed and on Friday the spacecraft mated with the PAF, the interface adapter...
