http://www.arianespace.com/mission-update/vega-flight-vv12-delay/

The liftoff of Arianespace’s Flight VV12 with Europe’s Aeolus satellite has been delayed by 24 hours due to winds at altitude over the Spaceport in French Guiana...With this one-day postponement, the liftoff of Flight VV12 is now set for August 22 at exactly 6:20:08 p.m., local time in French Guiana – pending an improvement of the wind conditions at altitude.

A mission to measure winds is delayed by strong winds. Oh... the irony... ;)

The delay is apparently related to VA241.

Its related the wind direction/speed in relation to the possible debris, these have been reevaluated after VA241.

However, the PR doesnt state if its linked to upper level winds or linked to safety....

Since the orbit altitude is 320 km, I wonder how much fuel Aeolus is carrying for reboosts?

ESA's facts and figures page for Aeolus has it as having 266 kg of fuel onboard.

Article by Jonathan Amos.

Aeolus space laser set to map Earth's winds

Quote
Aeolus is just a one-off demonstration mission, which raises the question of what happens when it inevitably reaches the end of its working life.
If it delivers on its promise, forecasters will be loath to lose the advantage. But it would not be Esa's role to produce a second spacecraft.
The agency is in the business of R&D, of trialling new concepts. It would be down to others to fund follow-on missions.
In Europe, this would fall either to Eumetsat, the intergovernmental organisation that runs Europe's operational weather satellites, or the European Commission through its own Earth observation programme, known as Copernicus.
It is conceivable also that international partners, such as the US and China, would be interested in lofting a constellation of satellites.

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.

In #Kourou the huge mobile gantry that surrounds and protects the #Vega rocket🚀 is starting to retract away from the launch pad. The mobile gantry is 50m tall and weighs over 1 million kg! It has protected #Aelous🛰🌬 and #Vega during preparation

What is the URL for the webcast?  I can't seem to find it on the Arianespace web site.
