In search of dark energy and dark matter

A European-built orbital satellite was launched into space on Saturday from Florida on a mission to shed new light on dark energy and dark matter, the mysterious cosmic forces scientists say account for 95% of the known universe.

Like the James Webb telescope, the Euclid will be positioned in a LaGrange point (L2, in this case), rather than in high Earth orbit.

If all goes well.

It’s interesting that the Guardian article says the telescope was “designed and built entirely by Esa,” although NASA supplied parts and its launching pad was made available and the telescope was launched using a SpaceX rocket. And ESA consists of nearly 2000 scientists from the US, Canada, and Japan as well as various European countries.

It’s a joint project. That’s how science should work in the first place.
