Neutral Ion Coupling Explorer - Mission Definition

Mission Definition

NICE will discover how winds and composition of the upper atmosphere drive the electric fields and chemical reactions that control Earth's ionosphere. The mission will resolve competing theories about the low-latitude ionospheric dynamo, and will explain how large-scale waves from the lower atmosphere can couple to the ionosphere and upper atmosphere. Understanding neutral-ion coupling in Earth's atmosphere has applications for solar and planetary atmospheres including Mars and Jupiter. NICE will be the first mission to simultaneously measure all the key parameters that both characterize and drive the ionosphere. It will remotely measure the neutral wind, temperature, composition, atmospheric and ionospheric density distributions as well as make in situ measurements of the ion motion. NICE uses flight-tested science instruments in a low-inclination orbit where the geometry magnetically links the in situ and remote sensing measurements.

Famous quotes containing the words mission and/or definition:

    ... [a] girl one day flared out and told the principal “the only mission opening before a girl in his school was to marry one of those candidates [for the ministry].” He said he didn’t know but it was. And when at last that same girl announced her desire and intention to go to college it was received with about the same incredulity and dismay as if a brass button on one of those candidate’s coats had propounded a new method for squaring the circle or trisecting the arc.
    Anna Julia Cooper (1859–1964)

    Scientific method is the way to truth, but it affords, even in
    principle, no unique definition of truth. Any so-called pragmatic
    definition of truth is doomed to failure equally.
    Willard Van Orman Quine (b. 1908)
