Today at 11:27 am CET the European Sentinel-5P satellite of the Copernicus program starts with a Rockot from Plesetsk Cosmodrome in northern Russia. In addition to the great fact that this launch is one of the few that takes place during the day and you do not have to stay up late or get up early, the mission of the Sentinel 5P is a remarkable one:
With its state-of-the-art Tropospheric Monitoring Instrument (Tropomi), it measures a variety of trace gases such as nitrogen dioxide, ozone, formaldehyde, sulfur dioxide, methane, carbon monoxide and aerosols. All of which affect our air in any way, influencing our health and our climate and making it so a very important mission for us and our planet.
In addition to the X-band subsystem, Tesat-Spaceom also provided several TTC transponders, which amongst other things take care of the correct positioning of the satellite in orbit.
