With the Gateway programme, NASA is returning to the Moon, which has long been argued as a favoured spot for large, ground-based telescopes. The lack of atmosphere provides all the advantages Hubble had, and the low gravity means telescope mirrors (which these days are made from fragments anyway, and not in a single piece) can be made larger. In addition, an orbit at a large distance from the Moon would provide good conditions for image stability without those pesky satellites. | With the Gateway programme, NASA is returning to the Moon, which has long been argued as a favoured spot for large, ground-based telescopes.

- | If the weather (clouds) become too much of a problem, or satellites begin to disrupt ground-based astronomy, the move into orbit around the Earth, Moon or Sun is always on the table, as is a move to the Lunar surface itself. But all this comes at a huge cost. It will be a long time before a general move beyond Earth will happen. | + | If the weather (clouds, high winds) become too much of a problem, or satellites begin to disrupt ground-based astronomy, the move into orbit around the Earth, Moon or Sun is always on the table, as is a move to the Lunar surface itself.
