Sources of Interplanetary Dust
The sources of interplanetary dust particles (IDPs) include at least: asteroid collisions, cometary activity and collisions in the inner solar system, Kuiper Belt collisions, and interstellar medium grains (Backman, D., 1997). Indeed, one of the longest-standing controversies debated in the interplanetary dust community revolves around the relative contributions to the interplanetary dust cloud from asteroid collisions and cometary activity.

“The American grips himself, at the very sources of his consciousness, in a grip of care: and then, to so much of the rest of life, is indifferent. Whereas, the European hasnt got so much care in him, so he cares much more for life and living.”
—D.H. (David Herbert)
“Even healthy families need outside sources of moral guidance to keep those tensions from implodingand this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.”
—Barbara Ehrenreich (20th century)
“We met. But all
We did that day was mingle great and small
Footprints in summer dust as if we drew
The figure of our being less than two
But more than one as yet.”
—Robert Frost (18741963)
