We've seen that missions to the Moon have very short lifespans. As soon as the two-week-long lunar night sets in, temperatures drop so low rovers and landers can't keep their batteries warm, ending their missions. A new paper proposes that a spacecraft in a halo orbit on the far side of the Moon could stay in perpetual sunlight and then beam power wirelessly to rovers and landers, helping them survive the lunar night and communicate from the far side.
