Sentinel-2A good for launch tonight

With fuelling of the launcher’s AVUM upper stage completed on Thursday and the launch rehearsed on Friday, all is ready for liftoff tonight set for 03:52 CEST (22:52 local time on 22 June). The men and women...

Sentinel-2 launch timeline

About 55 minutes after lift-off, Sentinel-2A will separate from Vega's AVUM upper stage and soar free into orbit, marking the start of the critical Launch and Early Orbit Phase.

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...

Sentinel-1A launch timeline

Find below a detailed timeline for the launch of Sentinel-1A on 3 April 2014. Lift off is set for 21:02:31 GMT (23:02:31 CEST) on board Soyuz ST flight VS07 from Europe’s Spaceport in Kourou, French Guyana. This...

Swarm goes into commissioning

Following Friday’s successful launch, the next critical milestone has been reached – the launch and early orbit phase, LEOP, is complete and the mission is now being commissioned. Immediately following separation, the three satellites started transmitting their...

ESA hands over control of the Metop-B weather satellite...

Yesterday, at 18:30 local time EUMETSAT took control of Metop-B operations, following the three-day Launch and Early Orbit Phase (LEOP) conducted by the European Space Operations Centre (ESOC) of the European Space Agency (ESA). The handover follows the launch of Metop-B on 17 September. Since Monday evening, teams at ESA’s European Space Operations Centre in Darmstadt, Germany, have been busy day and night during the Launch and Early Orbit Phase. As planned, they checked all of Metop-B’s systems and ensured that its solar array was deployed and oriented towards the Sun to provide crucial power to run the satellite and its 11 scientific instruments. On Day One, the ESA Flight Operations teams...

Metop-B to be handed over

Handover to Eumetsat is set to take place at 18:00 CEST today. At 14:45 today, the extended mission operations 'team of teams' at ESA gathered in the Main Control Room to witness the addition of the successful launch and LEOP for Metop-B to the history board running across the top of the back wall. A great tradition. Sweet!

H-Day: Metop-B handover to Eumetsat

Today around 18:00 CEST, 72 hrs after launch, ESA's Operations teams will hand over a very healthy Metop-B for routine operations to our colleagues at Eumetsat. ESA's Deputy Flight Director Andreas Rudolph just reported from ESOC's Main Control Room: All systems are on green. During LEOP, our jobs on the ESA side were: one orbit manoeuvre, routine hand-over activities, preparation of the memory system and uplink routine commands to ensure spacecraft autonomy (as of now). Our colleagues from Eumetsat will be happy to receive a spacecraft in great shape and on a precise orbit.

Today: orbit correction thruster burn

All goes well with the critical Launch and Early Orbit Phase (LEOP) activities at ESA's European Space Operations Centre in Darmstadt! Today, the mission operations team are focussed on completing the OCMs – orbit correction manoeuvres – that will gently nudge Metop-B into its final orbital position. There are thruster burn slots available at 20:46 CEST today and early tomorrow morning. In fact, Metop-B was delivered into an almost perfect orbit, so the manoeuvres need only be done within the plane of the orbit. From this morning's mission operations report (06:28 CEST): Metop-B has now completed almost 21 orbits and is continuing to perform excellently Orbit is nearly circular at about 801 km altitude,...

Update from ESA team in ESOC’s Main Control Room

The latest on Metop-B from the Main Control Room at ESA's Operations Centre in Darmstadt. We spoke earlier today with Deputy Flight Director Andreas Rudolph: All our systems are green! The ongoing post-launch tests & check-outs are proceding as planned. The Soyuz-Fregat launcher did a fantastic job, injecting Metop-B into its orbit at a precision of 3km and within 2 millidegrees of planned inclination.  Currently, Metop-B is at around 790 km altitude, moving toward the 817 km routine polar orbit. As planned, we have been checking spacecraft attitude, data handling, telecom links, software, back-up systems, solar array operation, power and temperatures. All look very well and, thus, 'nominal'. We will do further...
