LAUNCH ALERT!!!! 3rd LAUNCH IN 3 DAYS & 2nd HEAVY ROCKET IN TWO DAYS!!!
Thursday, August 29, 2013 at 2030 UTC (1630 EST) Arianespace will be launching the massive Ariane 5 ECA Rocket (designated Flight VA215) with a dual payload of satellites (EUTELSAT 25B/Es’Hail 1 satellite & GSAT-7) from Launch Site ELA-3 at the Arianespace Spaceport in Kourou, French Guiana.
Ariane 5 is a 2-stage expendable launch vehicle that carries payloads weighing more than 10 metric tons to geostationary transfer orbit (GTO) and over 20 metric tons into low-Earth orbit (LEO).
Ariane 5 ECA is the heavy-lift workhorse for missions to geostationary transfer orbit (GTO), and usually carries two satellite payloads. The Ariane 5 ES is tailored for low-Earth orbit missions with the Automated Transfer Vehicle – a resupply spacecraft for the International Space Station that weighs more than 19,000 kg. at liftoff. This Ariane 5 version also is capable of lofting satellites for Europe’s new Galileo space-based navigation system.
The primary difference from the Ariane 5 ECA configuration is the use of a storable propellant upper stage, which can perform multiple burns to deploy payloads into the desired orbit.
ARIANE 5 ECA CONFIGURATION EXPLAINED…….
ARIANE5 ECA = Heavy lift rocket that stands 53m (173.8ft) tall and is 5.4m (17.7ft) in diameter.
PAYLOAD FAIRING = The main payload fairing is a 2-shell fairing that’s 5.4m (17.7ft) in diameter and 17m (55.7ft) in length.
SECOND STAGE = Also called the Cryogenic Upper Stage or Etage Superieur Cryotechnique (ESC-A) is 5.4m (17.7ft) in diameter by 4.7m (15.4ft) in length. It’s powered by a single HM7B engine that burns liquid hydrogen and liquid oxygen (LOX/LH2) creating 14,000lb of thrust. Burn time for the second stage varies depending on the mission.
SOLID ROCKET BOOSTERS = 2 expendable SRBs known as Etage dAcceleration a Poudre or just (EAPs) are attached to the Ariane 5 and they provide about 90% of the thrust at liftoff. They each stand 31.6m (103.7ft) tall and are 3m (10ft) in diameter. They are each powered by a single engine that burns solid fuel (Ammonium Perchlorate, Aluminum Powder and Polybutadiene); burn time is 129 seconds.
MAIN CORE STAGE (1st Stage) = The Core Stage, known as Etage Principal Cryotechnique or (EPC-E) stands 23.8m (78ft) high and has a diameter of 5.4m (17.7ft). It’s powered by a single 1-Vulcan engine that burns liquid hydrogen and liquid oxygen (LOX/LH2) and burns for 650 seconds.
