Today I am proud to be a human. The Philae lander of the ESA's Rosetta spacecraft has been landed on comet 67P/Churyumov-Gerasimenko, after a voyage of 10 years. This morning at 8:04PM Philae Tweeted: "Touchdown! My new address: 67P! #CometLanding". Just typing that gives me chills.
Can't wait to see what we learn from this mission, but we've already created something important: a sense of inspiration. Few of us work on things which truly have universal impact, but this was one of them. Awesome!
