Media invitation: Last chance to see Arctic Weather Satellite in Europe

On 4 April, media representatives will have the opportunity to see the Arctic Weather Satellite up close in the cleanroom at OHB Sweden facilities in Stockholm, before the spacecraft is packed up and shipped to California, US, for a launch scheduled in June.

ESA’s Arctic Weather Satellite is a prototype mission that aims to improve weather forecasts in the Arctic - a region that currently lacks data for accurate short-term forecasts.

The satellite will build on existing Arctic monitoring satellites and will provide precise, short-term weather forecasts for the Arctic region. It is equipped with a 19-channel cross-track scanning microwave radiometer which will provide high-resolution humidity and temperature soundings of the atmosphere in all weather conditions.

The Arctic Weather Satellite is the forerunner of a potential constellation of satellites, called EPS-Sterna, that ESA would build for Eumetsat if the first prototype Arctic Weather Satellite performs well.

The constellation would supply an almost constant stream of temperature and humidity data from every location on Earth. This would, for the first time, allow for very short-range weather forecasting, or ’nowcasting’, in the Arctic. Meteorologists would use the mission to improve weather forecasts around the world.

The Arctic Weather Satellite mission will support research into climate change. Climate change is occurring at a faster pace in the Arctic compared to other parts of the world and these rapid changes are affecting the Earth system as a whole.

Embracing the concept of New Space, the Arctic Weather Satellite was developed and built on a very tight schedule. It took just 36 months from ESA awarding the industrial prime contract to OHB in Sweden to the satellite being completed.

From OHB’s premises in Sweden, the satellite will be shipped to SpaceX’s launch site in Vandenberg, California, in April. The satellite is scheduled to launch on a rideshare mission no earlier than June 2024.
