Stardust landing

Am I the only one who was reminded of "Andromeda Strain" upon seeing a
capsule that had travelled in outer space fall back on the ground in
remote area of USA ?


Out of curiosity, has NASA taken any steps to filly isolate/quarantine
the capsule ? From the video footage I saw, it didn't seem obvious at all.


Are the contents of the capsule still in vacuum, totally sealed from the
outside ? Or did it repressurise as the capsule re-entered our
atmosphere ?
