The Hubble Space Telescope is currently being serviced for the last time. Although the Hubble is projected to function for another five or so years, it'll soon be replaced by the James Webb Telescope and eventually the AT-LAST telescope. In many ways, it's the end of an era. Hopefully Project Constellation and the like will inspire a new generation of scientists (as well as science fiction writers) the same way the space shuttle and images from Hubble have.
I mean it's not neuroimaging or anything, but taking pictures that prove the expansion of the universe is still pretty neat. Here's hoping NASA eventually needs a cognitive neuroscientist.
Mission specialist Michael Massimino is twittering about the Hubble mission during his spare time... from the space shuttle. He's as awestruck and excited about being in space as one would expect. Basically, he sounds like he's having the time of his life. Check it out here.
