Washington Post: The National Reconnaissance Office (NRO), one of 16 US intelligence agencies, is giving NASA two telescopes, each as big and powerful as the Hubble Space Telescope.

Although NASA does not currently have money in the budget to use them, the telescopes could reduce the cost and shorten the timeline of a future mission. The gift was welcome news for the agency as it prepares for the planned demise of the Hubble, which will be decommissioned within the next few years.
