Webcast start is now at W-50:00 and counting.
Arianespace French voice checks were just started and expecting English voice checks to begin shortly.

Apparently due to high altitude winds...... (remember that it's a 1 sec window!)

Range weather (winds - same as Antares scrub 2).

An official announcement about and when want to retarget the launch should be on Arianespace website shortly.

CNES's Le Gall: Atmospheric balloon sent up 1 hr before Vega launch showed "very high" winds, which may not permit launch before Sunday.

If this is talking about local time..... this means a 48 hour turn-around.

Press Release

Arianespace Flight VV02: Vega – Proba-V, VNREDSat-1 and ESTCube-1; Launch postponed
Kourou, May 3, 2013

The weather conditions being unfavourable over the Guiana Space Center in Kourou, the European Space Agency (ESA) and Arianespace have decided to postpone VV02. VV02 will place into orbit the Proba-V, VNREDSat-1 and ESTCube-1 satellites.

Another launch date will be decided depending on the evolution of the weather conditions in Kourou.

Unfavorable high-altitude winds postpone Vega’s mission from the Spaceport with a trio of satellites
 
May 3, 2013 – Vega Flight VV02


High-altitude winds over the Spaceport in French Guiana have resulted in the decision by Arianespace and the European Space Agency to postpone tonight’s Vega mission with three satellite payloads.
 
This postponement was based on strict safety conditions applied for Arianespace launch operations.  The Vega vehicle and its three spacecraft passengers – Proba-V, VNREDSat-1 and ESTCube-1 – remain in a safe, standby mode at the Spaceport’s SLV launch site.
 
A new launch date will be decided based on the evolution of the weather conditions.
 
The Proba-V passenger for this mission is a 160-kg. European Space Agency spacecraft, designed to map land cover and vegetation growth across the Earth every two days.  Produced by prime contractor QinetiQ Space Belgium, it carries an advanced version of the Vegetation instrument.
 
VNREDSat-1 is a 120-kg. optical satellite for Vietnam, designed to support the country’s creation of an infrastructure to enable better studies of climate change effects, improving predictions for natural disasters and optimizing natural resource management.  It was built by Astrium on behalf of the Vietnam Academy of Science and Technology (VAST).
 
Joining these two payloads is Estonia’s ESTCube-1 student nanosatellite, which will test electric solar wind sail technologies and help establish the basis infrastructure for future Estonian space projects.  The 1.3-kg. cubesat was produced in a collaboration of students from the Estonian Aviation Academy, Tallinn University of Technology, Tartu University and the University of Life Sciences – and developed in conjunction with the Finnish Meteorological Institute and the German Space Center (DLR).

Strange that unlike previous Kourou weather scrubs that I have seen (usually quickly determining a 24 hour turn-around), it has been >14 hours since the scrub and still no new launch date updates from Arianespace/CNES/ESA. All local sources at CSG are saying that the earliest time the weather can clear is on the night of May 5/6 (e.g. https://twitter.com/StefanBarensky/status/330648400347422720), i.e. 48 hours delay, yet no official sources have reported that information......

So are they trying another attempt in 10 hours time (even if the weather forecast are pessimistic)?  ???

It is sounding more and more like NET Monday night because officials at ESA have said on twitter that Arianespace says it want's the area's strong winds downrange to settle further from this weeks recent cool front high, which passed through on the end of the weekend Sunday into Monday morning. An unofficial tweet from an hour ago indicated that Arianespace is likely going to defer setting a new launch date today for reasons about crew rest requirements in addition to the upper level winds.

Also, here is the accompanying image from yesterdays attempt that is located in the updated (expanded) press release shown above.

Looks very likely that the launch is now on Tuesday GMT: https://twitter.com/StefanBarensky/status/330916089473163264
