I'm seriously impressed as all get-out; GSO at 78:1
Fourth flight for biggest Ariane
Europe's most powerful rocket - the Ariane 5-ECA - has launched two
satellites from French Guiana.
It lifted off from Kourou spaceport at 1932 local time (2232 GMT),
carrying satellites for the Spanish defence ministry and a French
telecoms company.
The launch marked the Ariane 5's first flight this year and only the
fourth for the 780-tonne heavy-lift version.
The ECA has the power to push 10,000kg of payload towards geostationary-
orbit, 36,000km above the Earth.
To get the extra performance, the ECA's solid boosters carry more
propellant and the main Vulcain cryogenic engine has been modified to
improve its combustion of liquid oxygen and hydrogen.
The main difference compared with the generic vehicle, however, is the
introduction of a new upper stage based on tried and tested
technologies used on the much older, but now retired, Ariane 4
launcher.
Stephen Horgan,
How much tonnage to LL-1 if that task were given 29.5 days of taking
the fullest advantage of the sun and moon gravity?
