Dr. Henry Throop / University of Colorado Astronomy 1110 June 22, 2000 Lecture 13: NASA and the Operation of Science Announcements ------------- Pluto & comets : more next week Minute essays NASA budget ----------- Worksheet & project Operation of Science -------------------- Mars press conference This is first step As much as they'd like to, no one's saying that it is _proof_ of anything at all. In fact, they all say it's quite unexpected, and they don't have good explanations for it (e.g., water on north-facing slopes) Next step: let other people look at data Let them publish Someone looks at everything, or sees same features on Earth, which are not water It all gets revised Look at the data Publish (peer-review for technical accuracy) Look harder, broader Get more data Revise conclusions NB: this was a 'NASA press conference'. But really, NASA isn't in the business of doing science, just like NEA doesn't actually go out and make any sculptures themselves. NASA does give grants out to scientists, and also NASA does emply some scientists directly. Spacecraft missions ------------------- Voyager Galileo Magellan Viking Cassini Bunch of decisions: o Spacecraft or telescope? o Orbiter, Lander, Balloon, Flyby? o Big or small mission Budget Mass -- how long to get there o Where to send it? Venus -- has to endure heat if it's a lander o Sample return, in situ, or remote sensing Pluto -- o Can't do an `everything' mission! Or if you do, it's v. risky -- VG's: NASA budget, idl plots, pie charts, etc. Slides: shuttle, ISS, ground-based scopes Do: pick a target: mercury? Comet? Mars? Toys
