PLANETARY EXPLORATION!!! Logan Dougherty Quick Overview Mariner 2 First successful Venus flyby (USA) Mariner 4 First successful Mars flyby (USA) Venera 3 First Venus impact. Contact lost. (USSR) Venera 4 Venus atmospheric probe Claimed to reach the surface intact, but disproven shortly after by USA Mariner 5.

Right: The New Horizons spacecraft. Original Reasons for Planetary Exploration The Space Race Main memorable part of the Space Race is the Apollo mission Large competition in planetary exploration as well Between USA and USSR http://nssdc.gsfc.nasa.gov/planetary/chronology.html
As shown above, until the end of the Cold War, USA and USSR competed largely in their attempts to study the moon and the planets. Post Cold War, the USSR involvement declined heavily, leaving the USA to dominate the field NASA Space Science and Planetary Science Budget, 1959-2010 ($M, adj. to 2010) $7,000.000 $6,000.000 $5,000.000 $4,000.000 $3,000.000 $2,000.000 $1,000.000 $0.000 59 961 963 965 967 969 971 973 975 977 979 981 983 985 987 989 991 993 995 997 999 001 003 005 007 009

2 2 Space Science Planetary Science NASAs Big Questions for Planetary Science HOW DID THE SUN'S FAMILY OF PLANETS AND M INOR BODIES ORIGINATE? HOW DID THE SOLAR SYSTEM EVOLVE TO ITS CU RRENT DIVERSE STATE? HOW DID LIFE BEGIN AND EVOLVE ON EARTH, A ND HAS IT EVOLVED ELSEWHERE IN THE SOLAR S YSTEM? WHAT ARE THE CHARACTERISTICS OF THE SOLAR SYSTEM THAT LEAD TO THE ORIGINS OF LIFE? Presidents FY13 In-Guide Budget For FY13 Congress has passed a Continuing Resolution Under the CR PSDs FY13 budget is $1.19B
21% decrease from FY12 level Amazing Accomplishments Existence of bodies of water on Mars in the past. Atmospheric probes to help determine composition of other planets. Missions that help deduce the early evolution of planets and help to explain why our solar system formed how it did. Valuable samples of surfaces that offer insight into the formation of that planet. What inspires Planetary Exploration? Search for Life near Home Mars Signs of water, as discovered by rovers like Curiosity Venus People used to envision life existing there, but the harsh atmosphere makes it difficult to support life Titan Liquid lakes of ethane and methane
Colder than earth Atmosphere that consists of more than trace gases Where else should we search? Exoplanet Detection Kepler mission Uses transit method to detect dip in light curves Doppler Shift measurements Binary Movements Hundreds of planets have been discovered Planetary Detection is part of the Astrophysics sector of NASA as opposed to the Planetary Science, but offers useful information in the theory of how solar systems evolve. Exoplanets are popular The idea inspires people and the public is interested in the
possibility of finding planets with life What is the biggest difficulty in directly observing a planet? New Worlds Blocks out the stars light to gain a direct view of the planet. Can then study the spectra of the planet and gain knowledge of its atmosphere. Offers the possibility of finding planets capable of hosting life Reasons that policy makers may consider investing: While Kepler has produced results, the public keeps hearing about planets and it doesnt peak their interest. This would offer a more definitive statement on the possibility of life, and to see more detailed pictures of the planets, garnering more public support. Offers useful knowledge about planets in the habitable zone of stars. Space: the final frontier. Works Cited http://www.newscientist.com/data/images/archive/2542/25424001.jpg

Planetary Program seeks to answer fundamental science questions: 1. What is the inventory of solar system objects and what processes are active in and among them? 2. How did the Suns family of planets, satellites, and minor bodies originate and evolve? 3. What are the characteristics of the solar system that lead to habitable environments? 4. How and where could life begin and evolve in the solar system? 5. What are characteristics of small bodies and planetary environments that pose hazards and/or provide resources?
Planetary Science accomplishes these goals through a series of strategic-large, medium, small mission and supporting research 21 Planetary Decadal Recommendations Large Missions (Flagship-scale) Recommended Program Cost Constrained Program (budget increase for JEO new start) (based on FY11 Request) 1) Mars Astrobiology Explorer-Cacher descoped 2) Jupiter Europa Orbiter (JEO) descoped
