e. The Artemis program is a Moon exploration program led by the United States' National Aeronautics and Space Administration (NASA), formally established in 2017 via Space Policy Directive 1. It is intended to reestablish a human presence on the Moon for the first time since the Apollo 17 mission in 1972. The program's stated long-term goal is ...
The effects of spaceflight on the human body are complex and largely harmful over both short and long term. [ 1 ] Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia). [ 2 ] Other significant effects include a slowing of cardiovascular system functions ...
Artemis II →. Artemis I, formerly Exploration Mission-1 (EM-1), [ 9 ] was an uncrewed Moon-orbiting mission that was launched in November 2022. As the first major spaceflight of NASA 's Artemis program, Artemis I marked the agency's return to lunar exploration after the conclusion of the Apollo program five decades earlier.

The Moon is Earth's only natural satellite.It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
Gene Cernan on the Moon in the Apollo 17 lander with lunar dust stuck on his suit. Lunar dust is highly abrasive and can cause damage to human lungs, nervous, and cardiovascular systems. [1] Lunar habitation is any human habitation on the Moon. [2] Lunar habitation is provided by surface habitats, possibly as part of a moonbase.
It is the moon with the highest volcanic activity in the Solar System, as a result of the tidal forces from the planet and its oval orbit around it. Even so, the surface is still cold: -143 Cº. The atmosphere is 200 times lighter than Earth's atmosphere, the proximity of Jupiter gives a lot of radiation, and it is completely devoid of water.
