  1. Kaiya and Avery Spitzer space telescope

  2. Expectations • 1990’s- $2.2 billion • With new infrared detecting technology and research into cryogenic systems and orbits, currently costs 1/3 of original estimate to maintain • Mission estimated to last 2.5-5+ years (until liquid helium/cryogen wears out).

  3. Spitzer • Liquid helium depleted in 2009. The two shortest wavelength cameras still function today (Spitzer Warm Mission). • Launched from Cape Canaveral, FL on Monday, August 25, 2003. 3824 days since launch. 191,617,259 km from Earth. • 1990’s: infrared telescopes were around, but it was difficult to observe due to long exposure times and Earth’s Atmosphere.

  4. Expectations • Originally, it was proposed to go up for short duration 30 day flights (with launchings occurring every week). • By 1983, expected to be long duration. One of the first times a satellite was proposed to be far away from Earth and not trailing Earth’s orbit (protects it from heat and reduces amount of necessary coolant).

  5. Results • First telescope to capture light from extrasolar planets (“hot Jupiters”) • Gave new insight as to how planets are formed • More of a bar structure to the Milky Way Galaxy than earlier thought. • Double helix (80 light year long) nebula.

  6. Spitzer Basics • Infrared • 13 feet tall • 2,000 lbs. • Maps weather patterns • Launched August 25, 2003 • Lyman Spitzer died before it launched.

  7. Engineering • Has to stay hot and cold • CTA • Thermal radiation • IRS • IRAC • MIPS • Star tracker • Orbits behind earth • 85 cm mirror diameter • Ritchey Chrétlen design
