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. | ||||||||

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 | ||||||||
