First, a little bit of Blue Origin Kremlinology: They are advertising for a crew systems engineer. There are rumors that they are working on a manned suborbital ship but then again there are also rumors that they are working on a transdimensional intergalactic warp drive. Either way, it looks like they want to put humans on it.

Clark Lindsey has an interesting item on the development of GPS, with lessons for RLV development.

…and Derek Lyons starts strong out of the gate with a piece on the business practicalities of space access.

Update a few hours later: Check out Dr. Day’s detailed comment on GPS, which is meatier than either my post or the one I linked to. Good Stuff.
