"The American Astronomical Society (AAS) today expressed deep concern about the U.S. government's new restrictions on travel and conference attendance for federally funded scientists. Enacted in response to the budget sequestration that went into effect on March 1st, the policies severely limit the ability of many researchers to meet with collaborators and to present their latest results at professional meetings. The leadership of the AAS is especially worried about the restrictions' deleterious effects on scientific productivity and on scientists' and students' careers."
Keith's tnote: If you ask NASA how much they spend on travel in a given year they can't tell you. If you ask them how much these new travel restrictions to save they can't tell you that either. They are just making this up as they go.
