; and (2) the Administrator should continue to develop the Wide-Field Infrared Survey Telescope with a development cost (as defined in section 30104 of title 51, United States Code) of no more than $3,200,000,000. (b) Requirements The Administrator shall continue to develop the Wide-Field Infrared Survey Telescope to meet the objectives outlined in the 2010 National Academies’ Astronomy and Astrophysics Decadal Survey in a way that maximizes the scientific productivity of meeting those objectives for the resources invested. 306. Sense of Congress regarding small satellite science It is the sense of Congress that— (1) small satellites are increasingly robust, effective, and affordable platforms for carrying out space science missions; (2) small satellites can work in tandem with or augment NASA’s larger spacecraft to support NASA’s high-priority science missions; (3) small satellites are cost-effective solutions that may allow NASA to continue collecting legacy observations while developing next generation science missions; and (4) NASA should continue to support small satellite research, development, technologies, and programs. 307. Study on satellite servicing for science missions (a) Feasibility study Not later than 1 year after the date of enactment of this Act, the Administrator shall— (1) study the feasibility of using in-space robotic refueling, repair, or refurbishment capabilities to extend the useful life of telescopes and other science missions currently operational or in development
