* Lunar eclipses require a specific alignment: For a lunar eclipse to occur, the Sun, Earth, and Moon must be perfectly aligned, with Earth in the middle.
* Astronauts need sunlight: Astronauts on the Moon need sunlight to power their equipment and for visibility. A lunar eclipse means the Moon is in Earth's shadow, blocking out sunlight.
Therefore, it's physically impossible for astronauts to be on the Moon during a lunar eclipse.
