How The Instrument Works
A spectrometer inside the instrument measured the energy from two sources of space radiation: galactic cosmic rays (GCR) and solar energetic particles (SEP). As the spacecraft orbited the red planet, the spectrometer swept through the sky and measured the radiation field.
The instrument, with a 68-degree field of view, was designed to collect data continuously during Mars Odyssey's cruise from Earth to Mars. It stored large amounts of data for downlink, and operated throughout the entire science mission.

Famous quotes containing the words instrument and/or works:
“There is a hearty Puritanism in the view of human nature which pervades the instrument of 1787. It is the work of men who believed in original sin, and were resolved to leave open for transgressors no door which they could possibly shut.”
—James Bryce (1838–1922)
“Science is feasible when the variables are few and can be enumerated; when their combinations are distinct and clear. We are tending toward the condition of science and aspiring to do it. The artist works out his own formulas; the interest of science lies in the art of making science.”
—Paul Valéry (1871–1945)
