The Hubble Space Telescope has been in orbit for years now and has made some major discoveries during its life. Hubble is set to be replaced by the James Webb Space Telescope and NASA is looking past the James Webb to the more distant future. NASA is set to kick off a new mission called the Wide-Field Infrared Survey Telescope or WFIRST. WFIRST will take a much larger view of the universe than Hubble was capable of; NASA says that WFIRST will have a view 100 times as large as Hubble. According to NASA the wider view will help scientists to unravel mysteries of dark energy, dark matter, and to explore the cosmos.
