I went down to Cocoa Beach / Cape Canaveral, FL, for the New Horizons launch.
Launch was scheduled for January 17, with arrival at Pluto in July 2015. My
first introduction to Pluto was as an summer-research student in Flagstaff in
1993; I then spent the next summer at JPL, working on the Pluto Fast Flyby
(cancelled soon after). At SWRI, I've been involved for the last two years in
testing and science-planning for New Horizon's imaging spectrometer, named
Ralph. Now that the mission is in flight, its up-to-date location can be found
from APL's trajectory
page.
2021 Update: Happy Anniversary New Horizons! It's been 15 years since
launch, and I have been so lucky to be involved for most of that!
