She gives us visions to set beside the stunning images we're receiving even now from the surface of Mars. What Smith finds is radiant, grave, and mysterious, reaching through space like the most powerful telescopes-into the past and future. No wonder: her father was one of the engineers of the Hubble telescope. And like the most sensitive of telescopes, Smith looks powerfully and precisely, scattering her collecting array across the globe and the surrounding space. Smith's Pulitzer Prize-winning volume Life on Mars explores some of the same big questions. They may learn more about how the first stars and galaxies formed, about dark matter and the nature of gravity. It will also be in two times at once, allowing scientists to peer through space into the past. The Square Kilometre Array, named for the size of its collecting area, will be 50 times more sensitive than any present telescope and will be located in both South Africa and Australia. On Thursday, experts chose the site for the largest and most powerful telescope ever built-and it will be in two places at once.
