Our internal news board at work just had this item posted:
This is the first time JPL has ever had four spacecraft at Kennedy Space Center in Florida at the same time, getting ready for launches.
The JPL-managed Space Infrared Telescope Facility (SIRTF) is undergoing final preparations for launch at KSC aboard a Boeing Delta-II rocket. The second stage of the SIRTF expandable launch vehicle has been hoisted and installed atop the Delta-II first stage on a launch pad at the Cape Canaveral Air Force Station.
The two Mars Exploration Rovers are also at KSC, being prepared for launch.
I added the hyperlinks in the message. I’m not sure too many folks in the general public realize what a frenzy of design, build, and launch JPL has been going through lately.
