Teaming up for Sentinel-5P

26 September 2017

In this special edition of the Earth from Space video programme, Nico van Putten from the Netherlands Space Office and Jonathan Banting from Airbus Defence and Space discuss Sentinel-5P's unique Tropomi instrument and the challenges in building the satellite to accommodate it.
Referring to the news published on 25 September, users are informed that the ground segment anomaly has been solved and nominal Sentinel-2B production has resumed today, 26 September.

An unplanned maintenance of the Sentinels data distribution infrastructure has been required starting on 26 September at 11:49 UTC, resulting in a downtime of the Data Hub Services.

The teams that will fly Sentinel-5P are training intensively for launch, ensuring that everyone knows their job and can react to any emergency.
Engineers have been at Russia's Plesetsk launch site for a month now, ticking off the jobs on the ‘to do' list so that the Copernicus Sentinel-5P satellite is fit and ready for liftoff on 13 October. With the satellite now fuelled, the team has passed another milestone.
As a result of a ground segment anomaly, the publication of Sentinel-2B products in the Sentinel-2B PreOps Hub has been temporarily interrupted since the evening of 22 September, starting for products acquired from approximately 22:00 UTC.

Nearly 100 young scientists from 30 countries recently gathered at the Szent István University in Hungary, to attend a training course on land applications using satellite data and tools.

In this special edition of the Earth from Space video programme, Pepijn Veefkind from the Royal Netherlands Meteorological Institute discusses the Tropomi instrument on the Sentinel-5P satellite, set for launch on 13 October.
