The Federal Communications Commission (FCC) has issued a license to Swarm Technologies to operate a non-voice communications satellite constellation composed of 150 satellites smaller than an 1U CubeSat.

“Over 20 entities filed letters in support of granting Swarm’s application. These entities plan to utilize Swarm’s network to provide a variety of communications services in support of agribusiness, transportation, and academic and scientific research,” the FCC said in its memorandum approving the application.

Rocket Lab’s Electron booster successfully launched the “Make it Rain” rideshare mission for Seattle-based Spaceflight from New Zealand’s Mahia Peninsula on Saturday.

The mission lofted seven satellites, including: BlackSky’s Global-3 imaging microsat; two U.S. Special Operations Command (SOCOM) Prometheus reconnaissance CubeSats; two Swarm SpaceBEE satellites; Melbourne Space Program’s ACRUX-1 CubeSat; and one spacecraft from an undisclosed customer. The payloads weighed 80 kg (176.4 lb).

The BlackSky Global-3 imaging satellite was developed, designed and manufactured by BlackSky of the United States. The company is a provider of geospatial intelligence, satellite imaging and global monitoring services.

It was the sixth successful Electron launch in a row out of seven attempts and the third flight of 2019.  Rocket Lab has now orbited 35 satellites on its six successful missions.

The mission’s name was drawn from the high volume of rainfall in Seattle where Spaceflight is headquartered and at the Mahia Peninsula where Electron from which Electron is launched.











Swarm Reveals Why Satellites Lose Track

PARIS (ESA PR) — Satellite engineers have been puzzling over why GPS navigation systems on low-orbiting satellites like ESA’s Swarm sometimes black out when they fly over the equator between Africa and South America. Thanks to Swarm, it appears ‘thunderstorms’ in the ionosphere are to blame.
