More from Conference on Small Satellites

On Day 3 of the 20th annual conference, papers were presented on a variety of technologies, not all strictly related to small satellites, and on university satellites programs. The university group is very impressive: science projects have come a long way from dissecting frogs. University of Central Florida, for example, is equipping a microsat with a new kind of telescoping gravity-gradient boom which will stabilize the satellite precisely enough to allow for imaging.
ESA Director General Jean-Jacques Dordain rejected the idea of basing "small" on mass alone and outlined what he called a "light satellite" approach, based on flexibility of requirements, constrained cost, and acceptance of risk, which will sometimes, though not always, lead to a smaller spacecraft. He cited ESA's SMART-1 lunar probe as an example.
Overall, this year's conference included a greater variety of papers than ever, everything from broad examinations of what a small satellite is good for to extremely technical topics like a thermal control switch design and even a DARPA-funded project to allow accurate navigation anywhere in the solar system by using X-ray pulsars as reference points. Launch and launch opportunities remained a central concern, and in some cases a very sore point for experimenters who had depended for decades on Space Shuttle "GAS Can" opportunities. The "smallsat community" showed it was a vibrant, growing assembly of entrepreneurs, professors, students, large corporations, governments, and even international associations.
Happy 20th Birthday!
