From their Kickstarter page:
We’re sending a TARDIS into space!
November 23, 2013 is the 50th anniversary of Doctor Who, and we’re extremely excited. So excited, in fact, that we almost don’t know what to do… almost. Actually, we know exactly what to do: We’ve built a replica TARDIS and we’re sending it into orbit. Yes, really! We’re not talking about sticking a little, plastic TARDIS on top of a model rocket and shooting it really high into the sky (although that would be wicked cool). And we’re not going to tie a TARDIS to a weather balloon (which, by the way would also be pretty flippin’ awesome). No, we’re putting a TARDIS into the payload bay of a real, actual, honest-to-goodness, rocket, and launching it into a Low Earth Orbit.
Low Earth Orbit is where satellites need to be to actually “orbit” the Earth, not just fall back down. So, we’re talking about sending this thing, really, really, high… space high. The international space station is in Low Earth Orbit. Seriously. The guys on the International Space Station will be able to look out their windows and say: “Check out that police call box floating by.”
