NASA selects proposals for smallsats built to study deep space
NASA is expanding plans to use small satellites (aka smallsats) to explore the Solar System. The agency has picked two proposals for smallsat technology that would improve observations in deep space, where they could help improve models that predict space weather. One, Science-Enabling Technologies for Heliophysics (SETH), would demo both optical communications as well as a detector that can spot fast-moving chargeless atoms emanating from the Sun. Solar Cruiser, meanwhile, would include both a giant 18,000 square foot solar sail as well as a coronagraph that could study both the Sun's magnetic field as well as the velocity of coronal mass ejections.
