On track for launch from Cape Canaveral in July, NASA’s Perseverance rover has been secured to its rocket-powered descent stage and back shell, part of the protective shield that will safeguard the robot when it arrives at Mars next year.

Astronaut Scott Kelly, 143 days into a planned 341-day stay aboard the International Space Station, urged lawmakers Monday to restore full funding to NASA’s commercial crew program to avoid expected launch delays and continued sole reliance on Russia for transportation to and from the International Space Station.

The SpaceX Crew Dragon spacecraft that carried four astronauts to the International Space Station in November broke the record Sunday for the longest spaceflight by a U.S. crew vehicle, surpassing the 84-day mark set by an Apollo capsule on the final flight to the Skylab space station in 1974.
