Summary

This month, engineers from the Chinese Academy of Sciences' National Astronomical Observatories will drill into a limestone valley in a remote corner of Guizhou Province for a final round of geoengineering studies before breaking ground later this year on the 500-meter Aperture Spherical Radio Telescope (FAST), a massive instrument that the government hopes will thrust China to the forefront of radio astronomy. When FAST sees first light in 2014, it will measure more than five football fields in diameter, making it the largest single-dish radio telescope in the world.
