Back from Baltimore. The AMSAT meeting was interesting, and some of the hardware-oriented PTP people would have had a great time there. These were almost all radio amateurs, almost all east coast, who build metal boxes, circuit boards, and antennas, and launch the suckers, piggybacked as ballast on larger launches. Some of these devices are "cubesats", 10cm unit cubes that fit in a little spring powered box called a P-Pod that deploys 3 cubesats from the launch bus. A group of Naval Academy cadets are working on 1.5 unit cubesats (two per P-Pod) with a plug-in compartment for scientific experiments. When the experiment is over, the cubesat stays in orbit as an amateur radio repeater. There are a couple of groups working on Interorbital "tubesats", which are somewhat smaller, cylindrical, for $8K a pop (assuming they work). Combined with an electrodynamic tether for raising the orbit, I may use one of these for Server Sky testing. > 2) I can present Server Sky to PTP at next month's Monthly if you > folks are interested.

My talk at AMSAT went well. I am not a radio amateur (almost everyone else had call signs), but I told them I worked the unlicensed low power 12 cm band with PTP, and the 193 nanometer band, transmitting terapixel images through semiconductor photolithographic steppers. Photomask to chip distance is about the same number of wavelengths as an L Band amateur satellite to ground station . I would like to give a longer version of the Server Sky presentation (more explanation of space stuff) at the October 28th monthly meeting, and invite more folks from other groups. If this works for people, let me know.
