For Arianespace’s fifth launch of the year, and the first in 2018 with Vega, the company will orbit the Aeolus satellite – the world’s first space mission to acquire profiles of the Earth’s wind on a global scale, on behalf of the European Space Agency (ESA).
This will be the 12th mission of the Vega launcher, which once again is to demonstrate its versatility and perfect adaptation to European missions dedicated to Earth observation.
The liftoff will be from the Vega Launch Complex (SLV) in Kourou, French Guiana (South America).
DATE AND TIME
Liftoff is scheduled for Tuesday, August 21, 2018, at exactly:
-05:20:09 p.m., Washington D.C. time
-06:20:09 p.m., local time in French Guiana
-21:20:09, Universal Time (UTC)
-11:20:09 p.m., Paris time.
The nominal mission duration (from liftoff to separation of the satellite) is:
54 minutes, 57 seconds
TARGETED ORBIT FOR THE AEOLUS SATELLITE Sun-synchronous orbit (SSO)
The Launch Readiness Review (LRR) will take place on Monday, August 20, 2018 in Kourou, to authorize the start of operations for the final countdown.
ESA’s Aeolus satellite will be equipped with a single instrument: a Doppler wind LIDAR called Aladin (Atmospheric LAser Doppler INstrument) - an advanced laser system designed to timely and accurately measure global wind-profiles from space. Aeolus will probe the atmosphere with pioneering ultraviolet laser pulses, which will enhance the understanding of tropical dynamics and processes relevant to climate variability.
The Aeolus mission will provide much-needed data to improve the quality of weather forecasting, contributing to long-term climate research.
Flight VV12 is the embodiment of a long-standing, fruitful relationship between ESA and Arianespace. Indeed, it will be the 50th mission launched by Arianespace for the European Space Agency, guaranteeing independent and reliable access to space for Europe, and benefitting the world’s citizens through investments in space technologies.
Airbus Defence and Space is the Aeolus satellite’s manufacturer.
