October 3rd-8th was Space Week.
Dónal Nolan visited our school on Thursday 6th October . Dónal works for a company called Moog. Here are some interesting facts which he told us:
E.S.A. is the European Space Agency. It launches the Ariane 5 rocket 6-8 times a year. This rocket brings 2 satellites into space.Satellites are used by TV channels, G.P.S, mobile phones, communications and weather. Ariane 5 is launched from French Guiana near the Equator in South America. It is an unmanned rocket. Ariane 5 is powered by a vulcain engine. Moog which makes parts for the Vulcain engine.
The engine is built with Inconel 718 which withstands high temperatures. It is assembled in Vernon in France.
The rocket is fuelled by liquid oxygen and hydrogen.
The rocket is 54m high and weighs 800 tonnes.(about 400 cars)
When launched it reaches 3500kmph.
In 1996 an Ariane 5 rocket exploded on launch.
Parts of the rocket rained down on the nearby area.Dónal brought a piece of the rocket engine which had been found in a swamp.
There have been 74 accident free launches since then.
Each rocket costs about €100,000,000 and each satellite costs between €50,000,000 and €100,000,000.
The students found it very interesting.
