Due to a scheduled maintenance, access to the On-The-Fly (OTF) Online Dissemination System (OADS) for the ERS and Envisat (A)SAR data will be unavailable during the following time frame:

• Thursday, 26 April 2018 from 8:30 to 14:30 CEST

The launch of Sentinel-3B will complete the Sentinel-3 constellation and represents the culmination of months of training to fly Europe's latest Copernicus satellite.

The EOHelp service will be unavailable on Wednesday 25 April 2018, due to the ESA-ESRIN holiday closure.

ESA through its Earthnet Third Party Mission (TPM) programme is launching an ad-hoc call for  R&D applications with high resolution Digital Surface Model (DSM) products based on CartoSat-1 data.

The call for proposals is now open and will close on 25 May 2018.

The next Sentinel satellite for Europe's environmental monitoring Copernicus programme is poised for liftoff from the Plesetsk cosmodrome in northern Russia.

An orbit collision avoidance manoeuvre was performed on Swarm Bravo on 16 April 2018 at 16:10 UTC for a duration of 96 secomds equivalent to a Delta V = 2 cm/s.

The European Space Agency is organising 'EO4Alps' - The Alps from Space Workshop, which will take place from 27 to 29 June 2018 at the Villa Blanka Conference Center, in Innsbruck, Austria.

Users interested in participating still have until the 30 April 2018 to submit an abstract.

Due to an anomaly that occurred on the VFM (Vector Field Magnetometer) on board Swarm Charlie, the VFM science data (at 50 Hz rate) was not received from 13/04/2018 19:18 UTC to 16/04/2018 09:21 UTC.

From 16 April to 30 June 2018, public or private organisations involved in developing innovative applications based on Earth Observations (EO) and located in European GEO member countries are invited to come forward with voluntary Expressions of Intent for networking along the value chain.

Getting a satellite ready to be launched involves a long list of jobs, but with the Copernicus Sentinel-3B satellite now fuelled, this particular 'to do' list is significantly shorter. And, importantly, all is on track for lift-off on 25 April.
