advances with the successful test of the SLS rocket, aiming for a manned lunar mission by 2026.

NASA's Artemis program is a comprehensive and ambitious initiative designed to return humans to the Moon, with the ultimate goal of establishing a sustainable lunar presence and using it as a stepping stone for future missions to Mars.

The program's core objectives include landing the first woman and the first person of color on the Moon, thereby inspiring a new generation of explorers.

It aims to build a long-term base on the lunar surface and a small space station called Gateway in lunar orbit, which will enable continuous scientific research and technological development.

A key focus of the program is exploring the Moon's South Pole, a region believed to contain valuable water ice.

The Artemis program consists of a series of missions, starting with the successful uncrewed test flight of Artemis I in 2022.

This was followed by Artemis II, a planned crewed lunar flyby to test life support systems, and Artemis III, the mission that will see astronauts land on the lunar surface for the first time since the Apollo era.

Through a blend of international and commercial partnerships, the Artemis program is not only a symbol of space exploration but also a collaborative effort to shape the future of humanity's presence beyond Earth.
