Task: Put together a 20 minute presentation based on Planet Pluto. Special Notes: This was a group project consisting of Alice Vuong and John Bravo.Here is a list of links to various aspects of our project including Powerpoint Presentation as well as various Word Documents:Powerpoint PresentationOur HandoutsNew Horizons CostPluto: A Brief HistoryThe Drama1781: Uranus is officially discovered. Irregularities are noticed in it’s orbit. A search for the cause yielded the discovery of Neptune, a planet large enough to account for its odd orbit.1846: Neptune discoveredNeptune’s orbit is considered ostensibly irregular1905: Lowell theorizes a 9th planet is affecting the orbit of Neptune A search for “Planet-X” continues off and on.1916: Lowell dies. A understudy by the name of Clyde Tombaugh continues search for the theorized planet. Pluto’s Discovery1930: Discovered by Clyde Tombaugh at the Lowell Observatory in Arizona using a blink comparatorBlink Comparator: Compares two or more pictures of the same area over a specified time period. Computer programs have largely taken the place of this instrument.Oddities and CuriositiesThe name Pluto was intended to be reminiscent of the initials of Percival Lowell. Named After: Roman God of the Underworld, Percival LowellPluto is featured in Futurama as a habitat for penguinsTerrestrial PlanetsSmaller size and massHigher densityMade mostly of rock and metalSolid surfaceFew (if any) moons and no ringsCloser to the Sun (& closer together), with warmer surfaces.Jovian PlanetsLarger size and massLower densityMade mostly of gases (ergo “gas giants”)No solid surfaceRings and many moonsFarther from the Sun (& farther apart), with cool temps at cloud tops.Kuiper Belt ObjectsComets (ice and dust composition)Smaller size and massOrbit between Neptune and about 100 AU from the SunOrbit in the same direction and nearly the same plane as the planets.My Retriever RexComponent: REX (Radio Experiment)Primary Function: Communications ComponentSecondary Functions: Radiometry ModeTasks: Send/Receive information and instructions. Measure Pluto’s nightNew Horizons CostEstimated Cost: $650,000,000Launch Date: January 11th 2006Has a total of 7 instrumentsAlice the InvestigatorComponent: AlicePrimary Function: Spectrometer (“Like a prism, only better.)Tasks: Gather information about Pluto’s Atmosphere and search for an Atmosphere on Charon and other various Kuiper Belt objects. In Memory of RalphJuly 4th, 1998, my dog Ralph dies. Component: RalphPrimary Function: Mapmaker / TelescopeTasks: “Obtain high resolution color maps and surface composition maps of the surfaces of Pluto and Charon.” Other ComponentsPEPSSI: Plasma SensorSWAP: Wind AnalyzerLORRI: Camera, telescopeSDC: Dust counterPower SourcePowered by an RTG (Radioisotope Thermoelectric Generator.)What Happens: Radioactive material is placed inside a container surrounded by thermocouples that transfer heat to heat sinks and this generates electricityNuclear Reactors vs. RTGsNuclear Reactors produce far more power than an RTGNuclear Reactors can cause huge explosions!RTGs can't produce chain reactions potentially resulting in a nuclear explosionEnvironmental ConcernsRTG’s pose risk of nuclear contaminationThere is no danger of fatalities in case the container holding the nuclear material were to be destroyed during liftoffNew Horizons must have permission from the U.S. department of energy to use radioactive material to power New HorizonsIt is impossible for an RTG to have a meltodwnHOW TO MAKE PLUTO-POPS*BE THE ENVY OF THE BLOCK, WITH YOUR VERY OWN PLANET IN THE PALM OF YOUR HAND!Materials/Ingredients needed:1 box of Blue Raspberry Kool Aid Jammers ™*(*substitute with Blue Tropical Punch if above is unavailable).2 standard ice cube trays1 package of craft sticks (available from Michaels Crafts)6” of clear plastic wrap (2 sheets)1 very sharp paring/steak knifescotch tapeDirections:1.
