The Goldstone Apple Valley Radio Telescope Program (GAVRT) is:

An educational program involving three partners, NASA, JPL, and the Lewis Center for Educational Research (LCER). A K-12 program enabling students to become active members of a real science team

  • - they study planets, galaxies, and distant quasars using radio

astronomy

  • -they connect via the Internet to the Mission Control Center at

LCER

  • -they remotely control a 34-meter radio telescope, once part
  • f NASA’s Deep Space Network;
  • - they collect and analyze science data then forward it to professional

scientists

  • - they communicate with scientists.

Why send a spacecraft to Jupiter?

Juno will improve our understanding of the solar system by helping us understand the origin and evolution of Jupiter: Origin: Measure the water and the ice/rock core, to better understand how Jupiter formed. I nterior: Map the magnetic and gravitational fileds to understand Jupiter’s internal structure. Atmosphere: Map Jupiter’s deep atmosphere to understand the roots of the structure we see at the top of the clouds Magnetosphere: Study the radiation belts, aurorae, and the rest of Jupiter’s huge magnetosphere.

The Spitzer Space Telescope is the third of NASA’s planned Great

  • Observatories. It was launched in 2003. GAVRT is working with Spitzer in

developing a multi‐wavelength approach to studying the universe at infrared and radio wavelengths. Teachers wrote a proposal that was accepted for live

  • bservation using the Spitzer Space Telescope.
