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.
