Project Helianthus - a Solar Sail Driven Geomagnetic Storm Tracker

Solar storms captured the imagination of much of the American public earlier this year when auroras were visible well south of their typical northern areas. As the Sun ramps into another solar cycle, those storms will become more and more common, and the dangers they present to Earth’s infrastructure will continue to increase. Currently, most … Continue reading "Project Helianthus – a Solar Sail Driven Geomagnetic Storm Tracker"

Swarming Satellites Could Autonomous Characterize an Asteroid

An asteroid’s size, shape, and rotational speed are clues to its internal properties and potential resources for mining operations. However, of the more than 20,000 near-Earth asteroids currently known, only a tiny fraction have been sufficiently characterized to estimate those three properties accurately. That is essentially a resource constraint – there aren’t enough dedicated telescopes … Continue reading "Swarming Satellites Could Autonomous Characterize an Asteroid"
