Experiment MATI-75

Space experiment MATI-75 is dedicated to the 75th anniversary of MATI K.E.Tsiolkovsky Russian State Technological University and 150th anniversary of the founder of the theoretical space science Konstantin Eduardovich Tsiolkovsky.


  • To demonstrate the effect of shape and size recovery and stabilization when exposing to heating and cooling in zero gravity a plastic piece precompressed on the ground.
  • To give students and post-graduate students practical skills in staging a space experiment and conducting ground studies of foamed polymer material structure obtained in the ground and space environments.


To demonstrate and record on video the process of recovery under heating and stabilization under cooling of the shapes and dimensions of foamed polyurethane pieces.

Science Hardware Used:

  • Poroplast kit.

Flight Equipment Used:

  • HDV Sony HVR-Z1 video camera.


  • DVCAM video cassette.

Experiment Results:

  • Obtained samples: blocks (cubes, cylinders) and promotional materials (MATI-75 logo and K.E.Tsiolkovsky bas-relief);
  • Video records of the plastic foam size and shape recovery process.
