WASHINGTON: NASA is preparing to launch next month the Kepler spacecraft with a new space telescope that for the first time will be capable of detecting Earth-like planets outside our solar system, project managers said.
Kepler is scheduled for launch atop a Delta II rocket from Cape Canaveral Air Force Station, in Florida, on March 5 at 10:48 pm (0348 GMT, March 6). It will be the National Aeronautics and Space Administration’s first mission in search of Earth-like planets orbiting suns similar to ours, at just the right distance and temperature for life-sustaining water to exist.
“Kepler will push back the boundaries of the unknown in our patch of the Milky Way galaxy. And its discoveries may fundamentally alter humanity’s view of itself,” Jon Morse, astrophysics division director at the US space agency’s Washington headquarters, told a press conference Thursday. “The planetary census Kepler takes will be very important for understanding the frequency of Earth-size planets in our galaxy and planning future missions that directly detect and characterize such worlds around nearby stars,” he added.
Equipped with the largest camera ever launched into space — a 95-megapixel array of charged couple devices, known as CCDs — the Kepler telescope is able to detect the faint, periodic dimming of stars that planets cause as they pass by. At a cost of close to 600 million dollars, the Kepler mission will last three years and examine more than 100,000 sun-like stars in the regions of the Swan and Lyre constellations in the Milky Way. William Borucki, Kepler’s principal investigator based at NASA’s Ames Research Center in California, said the project was about finding places, where conditions are perfect for sustaining life.
