Contamination of spacecraft by recontact of dumped liquids

摘要: Liquids partially freeze when dumped from spacecraft producing particles which are released into free space at various velocities. Recontact of these with the is possible for specific particle sizes and velocities and, therefore, can become contamination experiments within or as a result waste potable water Space Shuttle. An examination dump characteristics was conducted on STS-29 using both on-board video records ground based measurements. A preliminary analysis data this flight indicates in range 30 to 75 ft/sec recontact limited sizes.
