A unique class 100 cleanroom was built to maintain the returned comet and interstellar samples in clean comfort, and to permit dissection and allocation of samples for analysis. ...
Because the samples are both microscopic and fragile, and distributed along impact tracks ranging from tens of micrometers to millimeters in size, it has proven to be a significant challenge to reliably ...
