The teams responsible for flying the Aeolus satellite completed a pre-launch ‘dress rehearsal’ at ESA’s ESOC operations centre in Darmstadt today, the last major step in getting ready for next Tuesday’s liftoff.
Experts in mission operations, flight dynamics, ground stations and software systems worked together with counterparts in the Jupiter Control Room on the far side of the Atlantic at Europe’s Spaceport in Kourou, French Guiana, to practise the pre-launch and liftoff sequence.

24-hour weather delay for Vega’s launch of the Aeolus satellite from French Guiana

Is it a wind-up, or have they got the wind up?

Esa is happy, Aeolus has separated, and in its correct orbit.

Title Highlights of Aeolus launch
Released: 23/08/2018
Length 00:02:24
Language English
Footage Type Music Clip

Description
Lifted into orbit on a Vega rocket from Europe’s Spaceport in French Guiana on 22 August 2018, ESA’s Aeolus satellite 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. The Aeolus carries one of the most sophisticated instruments ever to be put into orbit. The first of its kind, Aladin includes revolutionary laser technology to generate pulses of ultraviolet light that are beamed down into the atmosphere to profile the world’s winds – a completely new approach to measuring the wind from space.
Prior to liftoff, the satellite had been at the spaceport for around six weeks being tested, fuelled, encased in the Vega rocket fairing, rolled out to the launch pad and hoisted into the launch tower. Vega lifted off at 21:20 GMT (23:20 CEST, 18:20 local time) on 22 August. Some 55 minutes later, the upper stage delivered Aeolus into orbit and contact was established through the Troll ground station in Antarctica at 00:30 CEST on 23 August. The satellite is being controlled from ESA’s European Space Operations Centre in Darmstadt, Germany. Controllers will spend the next few months carefully checking and calibrating the mission as part of its commissioning phase.

Having worked around the clock since the launch of Aeolus on Wednesday, teams at ESA’s control centre in Germany have declared today that the critical first phase for Europe’s wind mission is complete.

The Aeolus satellite was launched on a Vega rocket in the evening of 22 August from Europe’s Spaceport in Kourou, French Guiana. With a launch mass of 1360 kg, including 266 kg of fuel, Aeolus will be the first-ever satellite to directly measure Earth’s winds from space.

Following the launch of Aeolus on 22 August, this extraordinary satellite’s instrument has been turned on and is now emitting pulses of ultraviolet light from its laser, which is fundamental to measuring Earth’s wind. And, this remarkable mission has also already returned a tantalising glimpse of the data it will provide.

Just one week after ESA’s Aeolus satellite shone a light on our atmosphere and returned a taster of what’s in store, this ground-breaking mission has again exceeded all expectations by delivering its first data on wind – a truly remarkable feat so early in its life in space.

It passes over at us at local dawn or dusk: among the most ambitious lasers ever flown in space, shining down to map Earth’s otherwise unknown global wind field. ESA’s Aeolus mission took more than two decades to reach this point. The laser was a key technology: in testing, the intensity of its beam was actually destroying the laser’s optical elements – the mission could not fly until this problem was fixed.

ESA’s Aeolus satellite, which carries the world’s first space Doppler wind lidar, has been delivering high-quality global measurements of Earth’s wind since it was launched almost a year ago. However, part of the instrument, the laser transmitter, has been slowly losing energy. As a result, ESA decided to switch over to the instrument’s second laser – and the mission is now back on top form.

Its also a sign that some political action is needed: There are no rules yet for collision avoidance between active spacecraft.

ESA had been mailing SpaceX since the launch of the first Starlink satellites, this had been the first time SpaceX replied. ESA expected Starlink to evade, because Aeolus was earlier in its orbit than Starlink. But SpaceX refused to react on a 1:1000 collision risk. While SpaceX does not comment this, ESA assumes that the electric propulsion system on the Starlink satellites is simply not capable of quick reactions, contrary to the chemical thrusters of Aeolus.
