NASA's 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 depending on the mission requirements. The SLS is built to be the most powerful rocket ever constructed, with the capability to lift heavy payloads into space. Its first uncrewed flight, known as Artemis I, is intended to test the rocket's systems and pave the way for future crewed missions, including those involving the Orion spacecraft.
