Too cool for words. Here is National Geographic‘s article about the time-lapse video of Earth taken over NOAA’s Deep Space Climate Observatory‘s (DSCOVR) first year in space. (SKIP THE SHORT VID at the top and go to the middle of the page.) The images were recorded from Lagrange point 1, a gravitational balance point (a Lissajous orbit) 1.5 million kilometers away. Jay Herman, EPIC Lead Scientist (what a cool title!), does a good job narrating.
There was an epic battle to get DSCOVR launched, and scientists waited seventeen years, from 1998, when then Vice President Al Gore proposed it, until early last year, to finally see the satellite’s launch. On July 6, 2015, they released their first image. It is the first image in the time-lapse that ended last month, at the end of the first year.
DSCOVR’s intent is to report on variable solar wind condition, warn us of coronal mass ejections, and monitor the things we and our planet do to impact the climate (hence, the link to Gore).
