WASHINGTON — As small satellites become more powerful, manufacturers say they need better ways to manage excess heat generated by their electronics systems.  Small satellites are increasingly handling more data, be it collecting remote sensing imagery or routing traffic for ground-based sensors and smart devices. Planet’s optical-imaging cubesats increased in onboard memory from 16 gigabytes

WASHINGTON — The percentage of small satellites that successfully complete their missions has improved in recent years even as the number of such satellites has dramatically increased. The Aerospace Corporation study, presented at the 34th Annual Small Satellite Conference, found that 87% of smallsats launched between 2009 and 2018 that had completed their missions had
