Flown piece of solar array from the Dragon C109 spacecraft, which launched from Cape Canaveral as part of the SpaceX CRS-7 mission on June 28, 2015. The fragment measures 1.25″ x 1.25″ and is encased in a Lucite display measuring 2.25″ in diameter. In fine condition.
The spacecraft for the SpaceX CRS-7 mission disintegrated just 139 seconds after launching from Cape Canaveral, just before the first stage was to separate from the second stage. It was the ninth flight for SpaceX's uncrewed Dragon cargo spacecraft and the seventh SpaceX operational mission contracted to NASA under a Commercial Resupply Services contract.
