Firing a satellite into orbit doesn't sound like exciting news, but yesterday's launch of Sentinel-2B really is.
Sentinel-2B will work with another Sentinel satellite to completely map the Earth's surface every five days. The Sentinel family is giving us a level of detail we've never had before. The data can be used by anyone for all sorts of things, from monitoring how cities grow, to studying wildlife habitats.
I think it's essential to measure the effects we're having on our planet. How else can we work out ways to fix the damage we're doing?
Sentinel-3A, a sister satellite of 2B, is currently featured in our Antenna gallery.
