Why Study Rocks in Space?<br />

NASA’s new directi<strong>on</strong> includes a human<br />

missi<strong>on</strong> to a Near Earth Object (asteroid) by<br />

2025.<br />

A current hypothesis suggests the sporadic<br />

meteoroid background was produced by<br />

cometary breakups, rather than sublimati<strong>on</strong> <strong>of</strong><br />

ice <str<strong>on</strong>g>and</str<strong>on</strong>g> dust from comet surfaces.<br />

The sporadic meteoroid envir<strong>on</strong>ment<br />

c<strong>on</strong>sists <strong>of</strong> a diffuse background <strong>of</strong> meteoroids<br />

that represents a c<strong>on</strong>tinuous risk to spacecraft<br />

throughout the year. The Meteoroid<br />

Envir<strong>on</strong>ment Office (MEO) has developed the<br />

NASA MSFC Meteoroid Engineering Model<br />

(MEM) to define the sporadic meteoroid<br />

envir<strong>on</strong>ment for spacecraft in interplanetary<br />

space <str<strong>on</strong>g>and</str<strong>on</strong>g> Earth orbit.
