The NASA Space Launch System (SLS) is a powerful rocket designed to carry astronauts and cargo beyond low Earth orbit. It is a key component of NASA's Artemis program, which aims to return humans to the Moon and eventually send them to Mars. The SLS features a modular design, allowing for different configurations to support various missions. The SLS is built to be the most powerful rocket ever constructed, with the capability to lift heavy payloads into space. Its first flight, known as Artemis I, was an uncrewed mission that tested the rocket's systems and paved the way for future crewed missions to the Moon.
