The average distance to Mars is 1.5 AU. If you send a command using radio waves (a form of light!) to a rover on the Mars surface, how long will you have to wait before you receive the response? Assume the probe responds immediately after it receives the command.
Pure, solid water ice has an albedo A≈0.35. What is the minimum distance from the Sun at which a rapidly rotating ice cube would remain frozen? Between which two planets does this distance lie?
Several years ago, NASA conducted the Lunar CRater Observation and Sensing Satellite (LCROSS)mission to look for evidence of water deep in craters near the south pole of the Moon(www.nasa.gov/mission_pages/LCROSS/main/index.html). Preliminary analysis of the LCROSS data hasalready demonstrated that there are indeed signifcant quantities of water on the Moon—a useful thingto know if we ever decide to build a permanent base on the Moon. The LCROSS spacecraft waslaunched from Earth aboard at Atlas V rocket on 18 June 2009. It was then sent on its way to the Moonby a Centaur transfer stage rocket. On 9 October 2009, while being observed by the LCROSS spacecraft,the Centaur rocket crashed into a crater at the south pole of the Moon creating a huge plume of Lunardust. Instruments on the LCROSS spacecraft measured the spectroscopic properties of this dust andradioed this data back to Earth for analysis. Then, 4 minutes after the Centaur rocket impacted theMoon, the LCROSS spacecraft itself…
