The National Aeronautics and Space Administration (NASA) may be thumbing its nose at White House orders that agencies improve their scientific integrity policies. An Aug. 5, 2011, NASA memo says the agency's existing policies are so good they don't need improving.

This from the agency that told eminent climate scientist James Hansen he could not talk to reporters without clearance from a 24-year-old Bush campaign volunteer who had falsely claimed that he finished college.

The existing NASA scientific integrity policies do not offer any clear guarantee that reporters can talk to NASA scientists without permission and supervision from the public affairs office.
