This is being sold on behalf of the Interstellar Store and can only be sold/shipped within the U.S. to U.S. citizens/organizations. No international buyers (sorry).The Challenger heat tile is 6"x 9"x 1.5" and was flown on STS-8 which was notable for carrying Guion Bluford, America's first african-american astronaut. Several chips and dings with one loose corner. Update: No longer available.

How often do flown tiles come off the orbiter with no damage? All of the ones I have come across have removal as well as flight damage. |

I'm really not sure, this isn't my usual field of expertise. I sold a Challenger tile a few days ago and it was pristine, so those two are all I have to go on. |

Many tiles removed from an orbiter, Chuck, do sustain some-type of damage. Others, though, can look to be in good condition from their surfaces. But it really all depends on a number of circumstances of why they're no longer installed and not of future flown status. |

I don't know the criteria other than visible damage for tile removal but I wonder if there is some sort of pull test performed and some tiles get removed purely due to inadequate adhesion. This would account for the less damaged tiles that turn up.Just an idea? |

Stress tests were mainly performed before any new tile could be installed on an orbiter.But during the shuttle program, usually anywhere between 30 to 100 tiles could be replaced before each mission. Some of them were damaged and lost during flight, while others were removed because workers needed to get access to support structures below them. A few, though, may had required a new engineering-type design requirement and were replaced with newer configurations.

That certainly does make for an interesting read, thanks Ken! |

Not sure if this has been posted before... a presentation discussing this topic, page 11 and 12 have detailed information for numbers of tiles removed per mission: Cost of Maintaining TPS |
