Technical Research on ISS Russian Segment

Vynoslivost Experiment


Objective:

Identification of the effect of space environment factors (SEF) on strain, strength and fatigue characteristics of the sampling materials exposed in loaded and unloaded configurations..

Tasks:

  • Mounting of panels with samples at the external surface of MRM2 Poisk during EVA;
  • Long-term exposure of material samples in loaded and unloaded configurations under the effect of SEF on MRM2 Poisk surface;
  • Dismounting of panels with samples from MRM2 Poisk external surface during EVA in a year (No. 2) and in three years (No. 1) and their return to the ground for the experiment results processing.

Science Hardware Used:

Sample exposure unit (SEU) consisting of:

  • Panels with samples No.No. 1, 2;
  • Transportation kit;
  • Kits for samples to be returned to the ground (2 pcs.).

Expected Results:

Development of recommendations for the updated assessment of life strength of the ISS RS pressure body structural elements and selection of durable structural materials.

Experiment Results:

Upon exposure the structural material samples returned to the ground.
