NASA and SpaceX successfully launched a long-awaited crew mission to the International Space Station (ISS), aiming to bring home U.S. astronauts Butch Wilmore and Suni Williams, who have been stranded on the orbital lab for nine months.

The duo, originally scheduled for a shorter stay, faced delays due to technical issues with their return vehicle. The new crew will also conduct scientific experiments and maintenance tasks aboard the ISS before facilitating Wilmore and Williams’ long-overdue journey back to Earth.
