First impression: Spirits, what a blasted hellhole of a wasteland. Nothing grew; nothing lived—nothing seemed to ever have lived here. Just barren rock—rough, scattered scree slopes. Cinder cones. Outwellings of solidified magma. Precipitous slopes, vertical cliffs ... klicks upon klicks of lunar landscape. For an instant I didn't know where the image of the lunar surface had come from, but then I remembered. Back almost a century ago, when NASA was trying out their Lunar Rover designs, they'd picked the Haleakala crater for the tests, because it was the closest to the rugged emptiness of the moon that could be found on this planet.
