High resolution images, but they decided to disable zoom on mobile. I don't understand why anyone does that.

I was curious what instruments this use, looks like a special form of radar? Does this mean it effectively gives us very accurate height maps regardless of cloud coverage, and is able to differentiate between what surface material it's seeing?

> Radar instruments can image Earth’s surface through clouds, precipitation, regardless of sunlight, making them particularly well suited for monitoring polar regions. The Sentinel-1C and -1D satellites also carry an Automatic Identification System (AIS) instrument – improving the mission capacity to detect ships and sea pollution. The Sentinel-1D AIS was also activated as the satellite passed over Antarctica capturing the presence of ships in these extreme areas.

I used to enjoy clicking through to the ESA Sentinel images, but then they kinda dried up for a while, or it was very hit and miss for updates. It would be nice to have regular daily or weekly upload. Our planet is so beautiful, as many of these Sentinel images show.

It’s honestly thrilling to see the E.U. step up in space research and the Earth sciences after King Pedophile shattered NASA and put the USA out of contention for a generation.

The EU tends to do very well in earth observations compared to the U.S. as some would say they are overall better. A lot of earth science and climate related fields tend to do better in the EU as well. For example, hurricane models tend to outperform their U.S. counterparts.

While we're talking about cool ESA achievements, the view of our universe Euclid gives us is incredible.

Check out this video they made if you want your mind blown: https://www.youtube.com/watch?v=rXCBFlIpvfQ
