  2. 2.9 m (9.5 ft) long 270 kg (570 lbs.) Dish: 2.74 m diameter 46 cm deep Spin Stabilized (5 rpm) 6 Hydrazine Thrusters Velocity Attitude Spin-Rate Control Powered by 4 RTG Power Sources Carries 11 Different Instruments Starlight Sensor – Referenced position relative to Canopus 2 Sunlight Sensors – Referenced position relative to the Sun Spacecraft Description

  3. Mission Overview • Designed to observe Jupiter • Earth’s 1st space probe to encounter an outer planet • Experiment to see if Asteroid Belt could be passed • Paved way for outer solar system exploration • Total cost as of 2001 – $350 million

  4. Message in a Bottle • Aboard Pioneer 10 &11 • Plaque with message from mankind • Not everyone approved

  5. Launch • March 2, 1972 at Cape Kennedy • Atlas/Centaur/TE364 Launch Vehicle • 51,810 km/hr (32,400mph)

  6. Flight Path

  7. Asteroid Belt • Encountered on July 15, 1972 • Materials range from dust particles to the size of Alaska (20 km/hr) • Once safely passed, Pioneer 11 launched (April 5, 1973)

  8. December 3, 1973 Approached at 132,000 km/hr 130,354 km (81,000 miles) above cloud tops - Mapped radiation belts - Located magnetic field Discovered Jupiter was a predominately liquid planet Jupiter

  9. 1st Close-Up Images of Jupiter

  10. Outer Solar System • June 13, 1983 – became 1st artifact to “leave the solar system” • Studied energetic particles from solar wind • Cosmic rays entering Milky Way • Scientific Mission End: March 31, 1997 • DSN – advanced concept study of communication technology for future probes

  11. Heliosphere

  12. February 7, 2003 – Last attempt Power source degraded – No power for transmissions 27,380 mph Currently 7.8 billion miles away Most remote man-made object Last Signal
