We will play Take5 until the end of Spring !

=> The end of SPOT4 (Take5) experiment was initially planned the 28th of May, but CNES just decided to extend it until the end of Spring.  The last SPOT4 images should be acquired around June the 21st. In France, and in many other countries, June 21st is the « Music Day » : we will be playing Take5 ’til the Music Day. In France, this extra time will enable us to monitor the end of winter crops and the start of summer crops, we will also see the end of snow melt in the mountains, and we will have more data to validate our algorithms. The total duration of the experiment will be around 5 months Many thanks to our CNES colleagues !
