Liquid Helium
Spitzer gets a much clearer view of the wavelengths that are blocked by the Earth's atmoshere
because it was so cool and everyone like it
As of today (13 Feb '14), the Hubble Space Telescope has been in space forthe past 8,696 days. It'll polish off a cool 24 yearson April 24, 2014 .
The Spitzer Space Telescope, launched in 2003, was equipped to observe in the infrared, at wavelengths of 3 to 180 micrometers (3,000 to 180,000 nanometers). The liquid helium that it carried, to cool its cryogenic detectors, was exhausted sometime in 2009, so the band of wavelengths is probably less now.
The fluid that keeps the body cool is sweat.
it keeps cool in the day maybe.
in a rocket or by space shuttles that land on planets and take photos also by telescope special ones that tell distances and take photos cool
space marines cool because they hot before now they cool.
theyre cool
it keeps the refridgerator cool
keeps it cool
It keeps stuff cool
