Circa 2017
NASA is beginning to design its next big astrophysics mission, a space telescope that will provide the largest picture of the universe ever seen with the same depth and clarity as the Hubble Space Telescope.
Scheduled to launch in the mid-2020s, the Wide Field Infrared Survey Telescope (WFIRST) will function as Hubble’s wide-eyed cousin. While just as sensitive as Hubble’s cameras, WFIRST’s 300-megapixel Wide Field Instrument will image a sky area 100 times larger. This means a single WFIRST image will hold the equivalent detail of 100 pictures from Hubble.
