  1. PLANETARY EXPLORATION!!! Logan Dougherty

  2. 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. • Pioneer 10 & 11 – Jupiter and Saturn flyby • Mariner 10 – Mercury flyby • Voyager 1 & 2 – Outer solar system • Pathfinder – Mars rover • Cassini Huygens – Saturn lander • New Horizons – Pluto and Kuiper belt • Curiosity Rover – Mars Rover

  3. Above: To the left is the Mariner 2 and to the right is the Voyager 1. Right: The New Horizons spacecraft.

  4. 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

  5. NASA’s Big Questions for Planetary Science • How did the sun's family of planets and minor bodies originate? • How did the solar system evolve to its current diverse state? • How did life begin and evolve on Earth, and has it evolved elsewhere in the Solar System? • What are the characteristics of the Solar System that lead to the origins of life?

  6. President’s FY13 In-Guide Budget • For FY13 Congress has passed a “Continuing Resolution” • Under the CR PSD’s FY13 budget is $1.19B • 21% decrease from FY12 level

  7. 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.

  8. What inspires Planetary Exploration?

  9. 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

  10. Where else should we search?

  11. 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

  12. What is the biggest difficulty in directly observing a planet?

  13. New Worlds • Blocks out the star’s 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 doesn’t 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 planet’s in the habitable zone of stars.

  14. “Space: the final frontier.”

  18. The Revolution in Planetary Science Planetary Decadal Reports from the National Academy of Science

  19. Planetary Science Objectives • NASA’s goal in Planetary Science is to “Ascertain the content, origin, and evolution of the solar system, and the potential for life elsewhere.” • Planetary Program seeks to answer fundamental science questions: • What is the inventory of solar system objects and what processes are active in and among them? • How did the Sun’s family of planets, satellites, and minor bodies originate and evolve? • What are the characteristics of the solar system that lead to habitable environments? • How and where could life begin and evolve in the solar system? • 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

  20. Planetary Decadal Recommendations Large Missions (“Flagship”-scale) “Recommended Program” (budget increase for JEO new start) “Cost Constrained Program” (based on FY11 Request) “Less favorable” budget picture than assumed(e.g., outyears in FY12 request) Mars Astrobiology Explorer-Cacher – descoped Jupiter Europa Orbiter (JEO) – descoped Uranus Orbiter & Probe (UOP) 4/5) Enceladus Orbiter & Venus Climate Mission Mars Astrobiology Explorer-Cacher – descoped Uranus Orbiter & Probe (UOP) Descope or delay Flagship mission Discovery $500M (FY15) cap per mission (exclusive of launch vehicle) and 24 month cadence for selection New Frontiers $1B (FY15) cap per mission (exclusive of launch vehicle) with two selections during 2013-22 Research & Analysis (5% above final FY11 amount then ~1.5%/yr) Technology Development (6-8%) Current Commitments (ie: Operating Missions)
