ملف:Meteoroid track through aerogel from EURECA mission.jpg

English: A 1.5 mm long impact track of a meteoroid captured in aerogel exposed to space by the European Retrievable Carrier (EURECA) spacecraft launched by STS-46 and recovered by STS-57. The wide end (open end) of the "carrot" is the location of hypervelocity entry into the 0.05 g/cc aerogel. As the particle is slowed by the aerogel the track narrows to a point. The 10 micron projectile is seen at the tip of the "carrot". See http://stardust.jpl.nasa.gov/science/sd-particle.html.
