SpaceX is set to launch the European Space Agency's Hera spacecraft aboard its Falcon 9 rocket on Monday. The FAA cleared Falcon 9's return to flight following a grounding over a recent malfunction. Hera will study the asteroid Dimorphos following NASA's DART mission, contributing to planetary defense research. SpaceX has faced FAA scrutiny, including a proposed fine for rule violations. CEO Elon Musk criticized the FAA, calling for the resignation of its administrator, Mike Whitaker.
