ESA has done a lot of good for public benefit with the Sentinel-1/2 missions. I happen to work with remote sensing and Sentinel data has been my entry point to the field.
I hope that ESA keeps pushing forward even more. I am afraid that although Sentinel missions are great, ESA projects are a bit demo-like and limited in scope. Europe should focus on scaling up and applying the tech, not just proving that ambitious projects are possible for their own sake.
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.

I am kind of confused by that statement, what more would you expect from the Copernicus Programme? Isn't it a technical improvements over NASA's LANDSAT programme?
Don't forget about Euclid, giving us by far the most in-depth view of our universe!
