Nearly a month after nailing a landing a rocket landing at Cape Canaveral, SpaceX plans to steer the next flight of a Falcon 9 booster toward a recovery vessel in the Pacific Ocean after a Jan. 17 blastoff from Vandenberg Air Force Base in California.

Ground crews have mounted the fully-fueled Sentinel 2B spacecraft, the next mission in Europe’s multibillion-dollar Copernicus Earth observation satellite fleet, on top of a Vega rocket inside a protective gantry on its launch pad in French Guiana for blastoff next month.

Touching down after 340 days in orbit, astronaut Scott Kelly and cosmonaut Mikhail Kornienko have returned to Earth from the International Space Station aboard a Soyuz crew capsule commanded by Sergey Volkov. Landing in Kazakhstan occurred at 0426 GMT Wednesday (11:26 p.m. EST Tuesday).
