Arianespace announced this week it is organizing a contest open to startups, labs, and universities for a free launch of a nanosatellite on a future rideshare mission, likely on an Ariane 6 or Vega rocket.

A U.S. military satellite that will fortify the “anytime, anywhere” communications infrastructure used by soldiers, ships, aircraft and drones was launched into orbit Thursday to improve the global connectivity that encompasses the planet.

SpaceX is gearing up for the first commercial launch of its powerful Falcon Heavy rocket as soon as early April with a communications satellite for Arabsat, and the U.S. Air Force hopes the two side boosters from the Arabsat mission can be safely landed and reused for the military’s first Falcon Heavy mission this summer, an exercise officials said will help certify previously-flown hardware for future national security launches.
