Live coverage: SpaceX Falcon Heavy launches NASA’s Psyche on mission to a metal asteroid

Sara Seager is an astrophysicist and planetary scientist at MIT, and she serves as deputy science director on NASA’s Transiting Exoplanet Survey Satellite, which aims to find planets around stars relatively close to the sun, searching for worlds that are ideal follow-up targets for missions like the James Webb Space Telescope.

SpaceX fired up a Falcon 9 rocket at Cape Canaveral Wednesday in a pre-flight test for a Starlink satellite launch Sunday, moving closer to the company’s final mission before sending two NASA astronauts into orbit for the first time May 27.

Stormy weather near NASA’s Kennedy Space Center kept SpaceX’s Falcon 9 rocket on the ground Thursday, delaying liftoff of a commercial supply ship with equipment and experiments for the International Space Station until Saturday.
