So, what makes it so onerous to construct on the moon? Properly, to begin with, it is coated in mud — presumably as a result of it has been a very long time since somebody’s completed a radical cleansing up there. However if you happen to’re picturing the identical kind of substance that accumulates beneath your couch, you are in for some dangerous information. Lunar mud is worse. A lot, a lot worse. This wonderful granular materials has a consistency nearer to powdered glass shards, which, as one may think, is a critical ache to work with. It is also electromagnetically charged from the unshielded bombardment of photo voltaic radiation. The mixture of small dimension, jagged form, and electrical cost causes lunar mud to stay to every little thing, jamming tools and inflicting abrasive harm.
The moon can be topic to a variety of temperatures, from roughly -200°F to 250°F. And, considerably paradoxically, a single piece of kit on the moon might be topic to each ends of this temperature vary on the similar time. The dearth of environment creates excessive temperature variations between direct daylight and shade. Many supplies do not maintain up nicely to this type of differential and both freeze, soften, crack, or disintegrate.
Then there’s the infrastructure on the moon — or, the obtrusive lack thereof. There is no telescope manufacturing unit up there. Each nut and bolt, each mirror and cable, and each circuit and processor wanted for a lunar telescope would should be hauled up from Earth, and finally examine, this was nonetheless an costly endeavor.
