Ariel: Contract signed to build European planet telescope
Airbus will lead the construction of the Ariel observatory which will study 1,000 distant worlds. …
“We will build the telescope out of aluminium, out of the same material, so that when it goes from room temperature to something that’s very cold – it should all shrink at the same rate; all the surfaces should deform together. If it’s perfectly aligned when warm, it should stay perfectly aligned when cool,” explained Paul Eccleston, the chief engineer at RAL Space.
