- Mission Lifetimes
All space missions end-- some with a whimper, some with a 'fwoosh' of reentry. For longevity, it's hard to surpass the twin Voyager probes. They have been flying steadily for almost 30 years (since 1977), have passed the heliopause's ...

- Geoid: What Earth Would Look Like Shaped Only By Gravity
Gravity does funny things. While the Earth looks rather round in pictures from space, the distortions that would have to occur in order to have uniform gravity everywhere would make it look more like...a potato, or a squashed basketball. ESA's GOCE ...

- Orbit Power Calculations
Fellow Tubesat pioneer Wesley Faler of Fluid&Reason has calculated power curves we can expect for our orbiting picosatellites. His summarized estimate is that 6-cell solar panel in a sun-synchronous polar orbit with perfect positioning can expect to p ...
