Sentinel-5P: satellite in excellent health
Paris (ESA) Oct 17, 2017
Launched last week, Europe's Sentinel-5P satellite - the first Copernicus mission dedicated to monitoring the air we breathe - is in excellent health. The 820 kg satellite was lofted into orbit from the Plesetsk Cosmodrome in northern Russia last Friday on a Rockot. The satellite will use its state-of-the-art Tropomi instrument to monitor our atmosphere, mapping a multitude of gases that affect the air we breathe, our climate and human health. After separating from the upper stage at a ... read more
