Next month's servicing mission marks the next-to-last planned visit to the Hubble Space Telescope, which NASA plans to turn off at the end of the decade. The Next Generation Space Telescope is slated to replace Hubble in 2009, but it will observe in the infrared range, leaving optical and ultraviolet astronomers without a major space-based instrument. To avoid being caught short, researchers this spring will start to tackle what scientific questions over the next 2 decades are best answered through space observations--and which technologies are needed to get the job done.
