Observation de la terre

Follow ESA's Earth observation missions as they are prepared for liftoff
  1. A look back at preparations for the 22 August liftoff of ESA’s Aeolus wind satellite from Europe’s Spaceport in French Guiana.  
  2. ESA’s Earth Explorer Aeolus satellite has been launched into polar orbit on a Vega rocket. Using revolutionary laser technology, Aeolus will measure winds around the globe and play a key role in our quest to better understand the workings of our atmosphere. Importantly, this novel mission will also improve weather forecasting. Carrying the 1360 kg Aeolus satellite, the Vega rocket lifted off from Europe’s Spaceport in Kourou, French Guiana, at 21:20 GMT (23:20 CEST, 18:20 local time) on 22 August. Some 55 minutes later, Vega’s upper stage delivered Aeolus into orbit and contact was established through the Troll ground station in Antarctica at 00:30 CEST on 23 August. Named after Aeolus, who in Greek mythology was appointed ‘keeper of the winds’ by the Gods, this novel mission is the fifth in the family of ESA’s Earth Explorers, which address the most urgent Earth-science questions of our time. “Aeolus epitomises the essence of an Earth Explorer. It will fill a gap in our knowledge of how the planet functions and demonstrate how cutting-edge technology can be used in space,” said Jan Wörner, ESA Director General. ESA’s Director of Earth Observation Programmes, Josef Aschbacher, added, “Aeolus carries the first instrument of its kind and uses a completely new approach to measuring the wind from space. Such pioneering technology has meant that it has been a demanding mission to develop, but thanks to all the teams involved we are thrilled that this extraordinary satellite is now in orbit. “We look forward to it living up to expectations!” Highlighted by the World Meteorological Organization, the lack of direct global wind measurements is one of the major deficits in the Global Observing System. By filling this gap, Aeolus will give scientists the information they need to understand how wind, pressure, temperature and humidity are interlinked. […]
  3. The Aeolus satellite lifted off on a Vega rocket from Europe’s Spaceport in Kourou, French Guiana, at 21:20 GMT (23:20 CEST, 18:20 local time) on 22 August 2018.
  4. Following 24-hour delay for the launch of Aeolus because of winds, everything looks good for the launch today at 23:20 CEST. With Aeolus ‘switched on’, teams at ESA’s European Spacecraft Operations Centre in Germany and teams at the launch site in Kourou are in position for liftoff.
  5. The launch of ESA’s wind mission Aeolus has been delayed 24 hours because of wind at Europe’s Spaceport in French Guiana. Read more from Ariancespace: 24-hour weather delay for Vega’s launch of the Aeolus satellite from French Guiana.
