Don't forget terrestrial observing from the ESO with ALMA, VLT, and the under construction ELT down in Chile.

Edit: If you watch the Euclid link above, please don't make the mistake I did and let the player auto select the crappy 720p50 version. Jump up to the 2160p version. It is more than worth it. But as advertised, if you are not impressed with Euclid's imagery after viewing the video, you must be dead.
