Abstract

Particles emanating from comet 81P/Wild 2 collided with the Stardust spacecraft at 6.1 kilometers per second, producing hypervelocity impact features on the collector surfaces that were returned to Earth. The morphologies of these surprisingly diverse features were created by particles varying from dense mineral grains to loosely bound, polymineralic aggregates ranging from tens of nanometers to hundreds of micrometers in size. The cumulative size distribution of Wild 2 dust is shallower than that of comet Halley, yet steeper than that of comet Grigg-Skjellerup.

The impact velocities for these low Earth orbit instruments are basically unknown but mean velocities are 15 to 17 km s –1 and thus beyond light-gas gun capabilities. Impact angles are random in low Earth orbit but they were constant and normal to the collector surfaces for Stardust.

The collector-wide surveys are complete and included all craters with D c >20 μm ( n = 63) and all tracks of D t > 100 μm ( n = 256). All SEM observations combined refer to a cumulative foil surface of <2 cm 2 (<2% of the collector surface); all detailed track data (e.g. fig. S3) refer to about 20 aerogel tiles in part incomplete and thus ∼13% of the total aerogel collector surface.

All calibration experiments were conducted at 6.0 to 6.2 km s –1 andusedprojectiles 10 to 100 μmin sizeand Stardust “flight spare” Al foils and density-graded aerogel targets. Experiments by Kearsley et al . in ( 7 ) used spherical projectiles of soda lime-glass (2.4 g cm –3 ) whereas polymethylmethacrylate (1.1 g cm –3 ) and hollow glass spheres (0.4 g cm –3 ) were used by Kearsley et al . in ( 8 ). Least-squares fits through the measured crater diameters (lip-crest to lip-crest) yielded the empirical constants K in the general relationship of D c = KD p . Corresponding experiments into Stardust aerogel are ongoing and presently limited to glass beads that produce carrot-shaped type A tracks ( 23 ); bulbous tracks remain uncalibrated because they can be produced presently only by clods of fine-grained material of undefined size or mass.

The encounter of comet Wild 2 by Stardust was the fourth flight project of NASA's Discovery Mission Program. Numerous individuals in government academia and industry contributed to the design manufacture launch cruise fly-by and safe return of the payload to Earth. In addition the research reported here was generously supported by our home institutions and national funding agencies.

Experiments by Kearsley et al . in ( 7 ) used spherical projectiles of soda lime-glass (2.4 g cm \u20133 ) whereas polymethylmethacrylate (1.1 g cm \u20133 ) and hollow glass spheres (0.4 g cm \u20133 ) were used by Kearsley et al . in ( 8 ). Least-squares fits through the measured crater diameters (lip-crest to lip-crest) yielded the empirical constants K in the general relationship of D c = KD p . Corresponding experiments into Stardust aerogel are ongoing and presently limited to glass beads that produce carrot-shaped type A tracks ( 23 ); bulbous tracks remain uncalibrated because they can be produced presently only by clods of fine-grained material of undefined size or mass."
