2.0 Mission Overview<br />
2.1 Mission Objectives<br />
The primary science goal of the STARDUST mission is to collect comet Wild-2 coma<br />
samples, plus bonus interstellar dust samples, in an aerogel medium, and return them to<br />
Earth. Additional science return is anticipated in the form of images of the comet coma<br />
and nucleus, Comet and Interstellar Dust Analyzer (CIDA) based dust particle analysis<br />
and dust flux monitoring.<br />
These science goals lead to the following objectives in the design of the STARDUST<br />
mission:<br />
• Provide a flyby of a comet of interest (Wild-2) at a sufficiently low velocity (less than<br />
6.5 km/s) such that non-destructive capture of comet dust is possible using an aerogel<br />
collector.<br />
• Facilitate the intercept of significant numbers of interstellar dust particles using the<br />
same collection medium, also at as low a velocity as possible.<br />
• Return as many high resolution images of the comet coma and nucleus as possible,<br />
subject to the cost constraints of the mission.<br />
More specific definition of the science objectives can be found in Section 2.4 Science<br />

2.2.1 Launch Vehicle<br />
The launch vehicle for STARDUST is a Boeing Delta II 7426. Given its four solid<br />
rocket motors and a Star 37FM upper stage without a Nutation Control System (NCS),<br />
thermal barrier or despin add-ons, it is capable of delivering 396 kgs at a C3 of 26 km 2 /s 2 .<br />

vehicle and Figure 2.2-1.b shows the launch vehicle itself.<br />
