More joys of the Astronomy Picture of the Day, a.k.a. APOD. I think this must be one of the best (and most cost effective) public relations efforts ever managed by NASA. I used to work at NASA Ames Research Center, and I remember how important PR was, given their steady diet of taxpayer’s cash. It’s a good arrangement… I want to see cool space pictures, and NASA wants to show them to me for free. Last week APOD featured this: Liftoff With the Space Shuttle, which led me to a bonanza of online video here: STS – 112 Video Index (which is to say, videos from space shuttle mission 112, the most recent one). I really must insist that you take the time to download the movie that shows the view looking down from the external fuel tank as the shuttle takes off. You get an unbroken visual record as the shuttle moves steadily from one world to the next. First there is the familiar view as from an airplane of grasslands, beach, and ocean. Then after only 90 seconds (17 miles high! 2800 miles per hour!) the scene has become a view from space, with tiny clotted splotches of cloud painted flat against a dim Florida coastline. The last frame seen from this camera shows the soft curvature of the earth clearly highlighted against the black void beyond.
Before I leave the topic of APOD, I have to mention another title that caught my eye: October 24 – Gullies on Mars. Since my last name is Gulley, you can imagine I looked long and hard for a peek at my Martian cousins, but to no avail. Still, if their house is somewhere in the picture, they must have a marvelous view from their back yard.
