I’m on the surface but my harpoons did not fire. My team is hard at work now trying to determine why. #CometLanding<script src="//platform.twitter.com/widgets.js" async="" charset="utf-8"></script>If you arent familiar with this, the ESA probe Rosetta was designed to study comet 67P/Churyumov-Gerasimenko up close and personal, and Philae is the lander that just set down on this monster of a rock. It's amazing news that I have been following and hope you all are as excited as me.
