The development of spacecraft systems and sub-systems requires high level testing, which simulates the harsh environment of space, e.g. vacuum, extreme temperatures or temperature gradients to state the robustness of the material and design. In addition, thermal-balance tests are performed to verify the thermal model of the systems.
The investigation and reduction of molecular contamination of parts and material is necessary to avoid in-orbit contamination of for example optical instruments. Volatile particles can be emitted e.g. by CFRP structures.
At STI, we offer testing in accordance to ECSS standards in clean room or laboratory clean conditions. We deliver state of the art testing services and holistically support for your testing campaign.

STI test center

At SpaceTech's test center, we can perform important common as well as extraordinary space simulation testing methods.

  • Thermal-Vacuum Cycling
  • Thermal-Balance Test
  • Bakeouts
  • Outgassing measurements with TQCM system and RGA
  • Thermal-Ambient Cycling
  • Thermal Shock Tests
  • Thermal Life Cycle Tests
  • Solar Simulation

Six thermal vacuum and two ambient pressure test chambers are available at STI´s test center at the headquarters.

Next to each chamber, areas for preparation are available. These areas include clean laboratory tables, tools and standard material, i.e. tapes. If required, STI can provide internet connection via Wi-Fi or LAN ports.

Special testing

At STI, we set new standards in space simulation testing with the use of oustanding equipment, examples are::

  • Thermal-Quartz-Crystal-Microbalance (TQCM): State of the art TQCM system by CrystalTek USA to measure the mass of outgassed volatile particles - contamination control inside the vacuum chamber.
  • RGA of Pfeiffer Vacuum: Mass spectrometer with world wide acknowledgement to measure the types of atoms and molecules in the vacuum system and the partial pressure of molecules and the presence low density gas like Helium during leakage tests.
  • The neonsee solar simulator uses unique steady-state solar simulation technology that allows for thermal balance testing.
  • For performance measurements of multi-layer-insulation (MLI), STI has developed a test bench.
