Unformatted text preview: Plan for Oct. 17 Jovian planets Sail on Voyager Asteroids are cratered & irregularly shaped. ' Galileo probe ﬂew by Gaspra & Ida (Dacty1)(1991 8; 1993); Craters! 0 NEAR probe ﬂew by Mathilde (1997); orbited Eros (2000), landed (2001) Eros is a near-Earth asteroid Orbit brings it close to Earth Compare the intensity of sunlight at Earth to Jupiter ‘ I a [M2 ' Jupiter’s semimajor axis is about 5 AU ‘ Assume an intensity of l for Earth ‘ So at Jupiter, I u 1/(5)2 = 1/ (5 x 5) = 1/25 ‘ Intensity of sunlight at Jupiter is 1/25 what is received at Earth COLD! Movie: Total Recall ' Good scene with pressure differential ' Depicts what it would be like if you were placed on martian surface - Low pressure - C02 atmosphere ' Terraforming Mars—10.000 year project (Robinson’s books: Red Mars, Green Mars, Blue Mars Inverse Square Law ’ Like gravity, the intensity of light seen at different distances from a source behaves according to an inverse square law. v This means that I on l/dz {intensity depends on (is proportional to) the inverse ofthe distance squared} Very different conditions are found in outer Solar System ' Much, much colder ° Gas giant planets rather than small rocky planets like Earth * Satellites of giant planets do have solid surfaces ‘ Voyagers 1 & 2 ﬂybys (1977—1989); both will escape from the Solar System "SAIL ON VOYAGER" & OUTER SOLAR SYSTEM WHILE VIEWING THE VIDEO IN CLASS ANSWER THE FOLLOWING QUESTIONS: 1. What special event made the exploration of the 4 jovian planets possible by Voyager? How rare is this occurrence? 2. What problems occurred early in this mission? 3. What major discoveries were made during the Jupiter flyby? 4_ How was volcanic activity discovered on 10? Why is 10 geologically active? 5. Comment on the appearance of the rings of Saturn. 6, How did Saturn's moon Titan appear? Why was Carl Sagan 'disappointed? 7. What preparations were made during Voyager 2's flight to Uranus? 8. What discoveries were made during the Uranus flyby? 9. Comment on the surface appearance of Miranda and give a possible explanation. 10. What discoveries were made during the Neptune flyby? 11. Comment on the surface appearance of Triton. 12. What message does Voyager carry to the stars? ...
