The spacecraft will spend two 13.70-day orbits observing each sector, mapping the southern hemisphere of sky in its first year of operation and the northern hemisphere in its second year. [37] The cameras actually take images every 2 seconds, but all the raw images would represent much more data volume than can be stored or downlinked.
“NASA is a strong organization today, but it has underfunded the future NASA,” Augustine said. Read more:Pete Theisinger, who led Mars rover missions for JPL, dies at 78.
The mission was planned to create infrared images of 99% of the sky, with at least eight images made of each position on the sky in order to increase accuracy. The spacecraft was placed in a 525 km (326 mi), circular, polar, Sun-synchronous orbit for its ten-month mission, during which it has taken 1.5 million images, one every 11 seconds. [ 19 ]
The Infrared Science Archive (IRSA) is the primary archive for the infrared and submillimeter astronomical projects of NASA, the space agency of the United States.IRSA curates the science products of over 15 missions, including the Spitzer Space Telescope, the Wide-field Infrared Survey Explorer (WISE), the Infrared Astronomical Satellite (IRAS), and the Two Micron All-Sky Survey (2MASS).
The video above shows a particularly frightening episode of this phenomena recorded in Germany as a child stands in the street bewildered by what he's hearing. Now NASA is stepping in to provide ...
Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare".It is caused by the reflection toward the Earth below of sunlight incident on satellite surfaces such as solar panels and antennas (e.g., synthetic aperture radar).

Both spectra and images are available in this way, and interfaces are made very easy to use so that, for example, a full-color image of any region of the sky covered by an SDSS data release can be obtained just by providing the coordinates. The data are available for non-commercial use only, without written permission.
