The light-weight of Arianespace/ESA's launch vehicles, Vega, is gearing up for its second flight that is planned to occur on April 20, 2013. Vega made its first mission in February 2012 delivering the LARES Satellite and multiple secondary payloads to orbit. Its second flight, VV02, will also deliver multiple satellites to orbit, ESA's Proba V satellite, VNREDSat for Vietnam and EstCube 1, a Cubesat from Estonia.

Preparations for the mission started at the ZLV Launch Site at the Guiana Space Center, Kourou, French Guiana, in February when the first stage of the Vega launcher was installed on its launch table inside the Vehicle Integration Facility. The P80 solid-fueled first stage was processed inside the Regulus facilities of the spaceport where it received its 88,400 Kilograms of HTBP bound propellant. Later, it was integrated with its nozzle and pyrotechnic initiators and the electrical harness and thrust vector control system was added. P80 delivers a total thrust of 2,261 Kilonewtons during its 107-second burn.

Once the first stage was in place atop the launch table and checkouts were complete, the 25,800 Kilogram second stage was installed on the vehicle after being processed itself. The second stage features a Zefiro 23 solid rocket motor that provides 1,196 Kilonewtons of thrust when making its 72-second burn.


The second stage was installed in late February to set the stage for the arrival of the third stage which was lifted atop the launcher early in March. The 11,000-Kilogram third stage is also solid-fueled featuring a Zefiro 9 motor that provides 225 Kilonewtons of thrust over the course of a 110-second burn.

A few days later, the fourth stage of the vehicle, called AVUM - Altitude and Vernier Upper Module, was attached to the launch vehicle. AVUM is a 1,000kg bi-propellant upper stage that can perform multiple engine burns using its RD-869 engine that provides 2.45 Kilonewtons of thrust. AVUM also contains the flight control system that sends commands to the lower stages.

With Vega fully integrated and waiting for its payloads, teams began final launch vehicle tests while the payloads were delivered to the Spaceport. Proba-V and VNREDSat-1A were delivered via a Boeing 747 aircraft touching down at the Félix Eboué Airport near the space center. The satellites will undergo final processing before being installed atop the Vega launcher.

    Key steps in integrating the Vega payload “stack” are shown in these photos. At left, the P2 Plate – on which VNREDSat-1 is mounted along with ESTCube-1 – is lowered into the Vespa dispenser. Vespa’s top-off with its cover (center photo) was followed by the placement of Proba-V atop the dispenser (photo at right), readying the stack for encapsulation in Vega's payload fairing – visible in the background.​

We're the 23 of April and the original post was quoting the 20 of April as the launch date, so what's the current launch schedule ?

Arianespace VV02 – Proba-V, VNREDSat-1 and ESTCube-1: Launch postponed by 24 hours

Evry, April 25, 2013

To carry out additional checks on the mobile gantry system used on the Vega launch complex (SLV), the European Space Agency (ESA) and Arianespace have decided to postpone the Vega launch VV02 for 24 hours. It was originally scheduled for the night of May 2 to 3.

Liftoff is scheduled for the night of May 3 to 4, 2013, at exactly:

11:06:31 pm (local time in French Guiana, on May 3, 2013)
10:06:31 pm (Washington, DC)
02:06:31 (UTC) on May 4, 2013
4:06:31 am (Paris)
9:06:31 am (Hanoi)​
 
So, there don't allowing to delay the launch to launch the Vega 3 hours later? I don't think that I can do a very early wake-up for see this launch :P
 
Spaceflight Now says so at least:
Spaceflight Now said:
SATURDAY, MAY 4, 2013
0140 GMT (9:40 p.m. EDT Fri.)
SRUB. Tonight's Vega launch has been postponed due to unfavorable high-altitude winds at the launch site. We're waiting on word on when Arianespace will make another launch attempt.
 
Arianespace 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.​



Arianespace: Unfavorable high-altitude winds postpone Vega’s mission from the Spaceport with a trio of satellites
 
For some reason no updates were given, but all sources at CSG are now reporting the earliest time another try will be done is on Tuesday morning GMT (i.e. just under 2 days from now).
 
Spaceflight Now: Vega rocket set for launch tonight after weather delay

Arianespace says there will be another attempt to launch Europe's second Vega rocket tonight after a three-day delay to wait out unfavorable winds aloft. Liftoff from French Guiana is set for 0206 GMT Tuesday (10:06 p.m. EDT Monday).

An Arianespace spokesperson says there will be another Vega launch attempt this evening after the flight was delayed from Friday to wait out brisk easterly high-altitude winds.

The winds have died down enough for officials to conclude there is a chance the conditions will be favorable at launch time tonight, which is set for 0206:31 GMT Tuesday (10:06:31 p.m. EDT Monday).
