Lunar liquid mirror telescope. Artwork of a giant liquid mirror telescope (centre left) on the surface of the Moon. The Earth is at upper right. This possible future telescope is 1 kilometre wide and 1 kilometre tall, here in a crater near the Moon's south pole. A lunar base is in the foreground, with landing pads (centre right) for rocket transports (one seen ascending below the Earth). A liquid mirror telescope uses a reflecting liquid as the primary mirror. The Moon's low gravity and lack of distorting atmosphere makes it an ideal location for such a telescope, which would use low-temperature ionic liquids, and be used for infrared observations.
