Assuming the last-ever space-shuttle launch goes off as scheduled tomorrow morning, here are two unique, local ways to experience it: West Seattle’s NASA Solar System Ambassador Alice Enevoldsen will comment and discuss via Twitter – she explains on her Alice’s Astro Info site how that will work. Not far from West Seattle, you can also join a free viewing party at the Museum of Flight, which will open early for the occasion. The launch is scheduled at 8:26 am our time; the museum will open at 8 am, and you can watch in their big-screen theater. (If you want to see the rest of the museum afterward, that’ll still cost you.)
