Homework # 3 is due October 21. See syllabus for details. Lecture Summary (10/12 & 10/14) Landers, orbiters, and rovers have been exploring Mars over the last 4 decades. Views from the surface taken by the Martian rovers were shown. Asteroids lie mostly between the orbits of Mars and Jupiter, yet some have Earth-crossing orbits. Recently probes have flown past Halley's comet, and 4 asteroids, if you include Dactyl. The near-Earth asteroid, Eros, was studied during the NEAR mission. The extreme drop in the intensity of sunlight was highlighted before moving to planets of the outer solar system. Jupiter was used to introduce the jovian planets (Jupiter, Saturn, Uranus, Neptune). These planets are massive, large, have many moons, ring systems, and low densities. Jupiter’s Great Red Spot is an atmospheric feature. Saturn’s rings lie within the Roche Limit as do the other ring systems. Magnetic fields for jovian planets result from an interior region comprised of liquid metallic hydrogen. Inside each of these planets is a rocky core.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
