Congratulations to ESA and everyone involved in the successful Sentinel-1 launch on 3 April 2014 . This new C-band SAR satellite is going to provide abundant new data to monitor the polar regions. The Polar View programme (www.polarview.aq) will be making extensive use of the images to provide timely information about sea ice in the Arctic and Antarctic. Data should start flowing in the next few months after the commissioning phase – we’ll keep you posted. But for now congratulations again to all involved and enjoy the launch video taken from onboard cameras.
