Astronaut Scott Kelly and cosmonaut Mikhail Kornienko are making final preparations for return to Earth Tuesday evening, closing out a record 340-day stay aboard the International Space Station where they served as medical test subjects to learn more about the long-term effects of weightlessness, space radiation and isolation.

For the third time in 10 days, SpaceX is readying a Falcon 9 rocket for launch Sunday from Florida’s Space Coast with another 60 Starlink internet satellites. This time, SpaceX aims to extend the record for reusing a Falcon 9 booster to nine flights.

SpaceX launched a Falcon 9 rocket from Vandenberg Space Force Base, California, with 51 small satellites, hosted payloads, and orbital transfer vehicles heading into polar orbit on the Transporter 7 mission. Liftoff occurred at 11:48 p.m. PDT Friday (2:48 a.m. EDT; 0648 UTC Saturday).
