SpaceX’s Falcon 9 rocket sent dozens of satellites into orbit today with a launch that featured an unusual on-the-ground touchdown for its first-stage booster.
Eighty-eight spacecraft were packed aboard the rocket, which took off from Cape Canaveral Space Force Station in Florida heading for a pole-to-pole orbit. That sun-synchronous orbit is typically preferred for Earth observation satellites, of which there were plenty.
Two of the spacecraft were Sherpa orbital transfer vehicles built by Seattle-based Spaceflight Inc. One of the Sherpas used a electric propulsion system to maneuver in space and deploy satellites into different orbits. The other was a free-flier.
