Build Your Own G-Force Test Rig
May 18 2012
Rockets are powerful stuff, and satellites and astronauts experience tremendous G-forces pushing down on them during launch. For picosatellite work, it is necessary that your design be able to withstand forces equivalent to perhaps 10 times Earth gravity-- 10Gs. To test this, the easiest way is to build a centrifuge.Think… read moreOrbital Debris And Space Weather?
May 08 2012
I've some background in space weather-- the influence of solar activity on Earth and near-Earth orbits. My new job as a professor at Capitol College has brought me into contact with several bright students working on using picosatellites to test our orbital debris removal concepts. Further, the number of other… read moreApril 01 2012
We are fortune here at Science20 to have come across an early work by Gaston Leroux. This manuscript was dated to 1899, suggesting it was an early, discarded draft of the work that later came to be known as "The Phantom of the Opera". Current speculation is Gaston changed the… read moreKey Trades & Mission Scenarios

Calliope integration and testing is on hold until Spring break, possibly until Summer. This is driven by two factors: my new job has me short on time, and InterOrbital's deadlines have removed a strong time pressure. It's a good situation-- it's always better to have more time.One aspect of my… read moreState Of The Picosatellite Universe
February 12 2012
While I've been strangely silent, the space industry is surging ahead. I have, off the record, been told of small companies looking to invest $10s of millions into launchers, of new picosatellite designs (like Cubesat and Tubesat) being bandied about, of a possible new East Coast space port. NASA is… read moreAlso find Sandy on:
