In Space
Geoffrey A. Landis proposed in 1989 that a mobile base or city on the moon could move to remain constantly in sunlight, allowing the use of solar power and avoiding the darkness and cold temperatures of the lunar night. He later suggested that the same concept could be used on the planet Mercury, where a mobile base or city could be used to avoid sunlight by staying in the temperate twilight region near the terminator, although this concept had previously been anticipated by the science fiction writer Kim Stanley Robinson in 1986.
On Mars and the moon, Robert Zubrin proposed that landing vehicles could be equipped with legs such that they could "walk" across the surface to link up to form larger habitat units.

Famous quotes containing the word space:
“The flattering, if arbitrary, label, First Lady of the Theatre, takes its toll. The demands are great, not only in energy but eventually in dramatic focus. It is difficult, if not impossible, for a star to occupy an inch of space without bursting seams, cramping everyone else’s style and unbalancing a play. No matter how self-effacing a famous player may be, he makes an entrance as a casual neighbor and the audience interest shifts to the house next door.”
—Helen Hayes (1900–1993)
“The merit of those who fill a space in the world’s history, who are borne forward, as it were, by the weight of thousands whom they lead, shed a perfume less sweet than do the sacrifices of private virtue.”
—Ralph Waldo Emerson (1803–1882)
