For decades, the development of the HEXAGON reconnaissance satellites was cloaked in secrecy, a veil only recently lifted by the NRO. Dwayne Day examines a new book by one of the key people involved in the HEXAGON program that offers a behind-the-scenes account of designing the most complex mechanical device ever flown in space.
Much of the general public thinks NASA’s budget is much larger than it actually is, and as a result it shapes their willingness to support the space agency’s activities. Alan Steinberg describes research he performed to see if adjusting the public’s knowledge of NASA’s budget increases their support for the agency.
The last two decades have seen an avalanche of extrasolar planet discoveries, raising hopes that the discovery of a true Earth-like exoplanet is around the corner. Jeff Foust reviews a book that offers an eloquent overview of the state of research and the possibility these discoveries will come to a halt just as we’re on the verge of ending our cosmic solitude.
