[Abstract] Matter in the interplanetary missions is exposed to Galactic Cosmic Rays (GCR) enhanced by intermittent solar flare energetic matter. These impinging GCR on spaceship materials as well as astronaut’s body, leave a variable damaged volume. That can be indirectly visualized by PADC detectors. Passive matter has been employed advantageously for space dosimetry; in that, etched nuclear tracks provide information on the LET value, mass and energy of impinging radiation. Here we suggest employing the etched nuclear tracks observed on the PADC detector surface, to predict damages in space matter. Information is obtained from track´s geometrical shape such as pit aperture, track length, direction, and nuclear reaction product as well as the impinging beam intensity, energy and particle mass. The suggested method provides insight of permanent or temporal atomic and molecular alteration in matter structure, space electronics including quantum computing expected failure rate.
