Voice 1: NASA wanted the Stardust to cross paths with a particular comet named Comet Wild Two. However, the comet was moving very fast and it was very far away! But the scientists were prepared for that. By using mathematics they were able to time exactly when the Stardust and the comet would meet. Their plan was to have the Stardust orbit the sun three times. On its third time around the Stardust and Comet Wild Two would cross paths. The Stardust would then be travelling at the same speed as Comet Wild Two.
聲音1：美國航空航天局希望星塵號與“懷爾德2號”彗星相遇。但是，這顆彗星的移動速度非常快，而且距離非常遠！不過科學家為此做了充足的準備。通過數學運算，他們準確地測定了星塵號和該彗星相遇的時間。他們的計劃是讓星塵號繞太陽運轉三次。在第三次繞日運轉時，星塵號會和“懷爾德2號”彗星相遇。屆時星塵號將和“懷爾德2號”彗星以相同的速度移動。
Voice 2: The Stardust and the comet had to be travelling at the same speeds. If the comet had been travelling faster, the comet's particles would hit the Stardust. Small, fast-moving particles could have easily destroyed the Stardust. But if the Stardust had been travelling faster than the comet, it would have passed the comet by. It would not have been able to gather the materials the scientists wanted.
聲音2：星塵號和這顆彗星必須以相同的速度移動。如果彗星的移動速度更快，那它的顆粒就會撞上星塵號。小且移動速度快的顆粒可能會輕易地毀壞星塵號。但是如果星塵號的移動速度快于彗星，那它就會錯過彗星。星塵號就不能收集到科學家想要的材料了。
