The international space station is revolving around the Earth just 400km above its surface, which means it is spinning in low orbit (Figure 1). The station hovers in the atmospheric layer called the thermosphere, which surprisingly, is not completely devoid of atmospheric molecules. Satellites supporting global positioning systems on the surface of the Earth hover much higher and their successful operation relies on being able to function in the high vacuum of outer space.

Space Simulation Systems
Engineers and scientists who design and develop the systems that are utilized at different distances beyond the Earth’s surface require a means to test the system while it lies on the surface of the globe. Researchers and engineers developing space-destined technology, or those exploring how low pressure environment conditions affect matter, can benefit from using Angstrom Engineering’s space simulation systems (Figure 2).

These systems give the required environmental condition to effectively test and finish the task. Both engineers and scientists can obtain precise data on the way their components will operate under varied temperatures and pressures. However, it is necessary to ensure that all the components deployed in outer space and the upper atmosphere are subjected to stringent testing to make sure that they can withstand the strain of these adverse conditions.
Pressure and Temperature Controls
In order to replicate the environment beyond the atmosphere, sophisticated temperature and pressure controls are required. To obtain pressure control, vacuum engineers at Angstrom have developed a unique pressure vessel that can reach high vacuum by means of turbo-molecular or cryogenic pumps in tandem with a mechanical roughing pump.
The temperature control system involves a combination of actively heated and cooled surfaces along with the use of solar selective coatings to absorb excess radiation and remove it from the system. Angstrom was able to achieve excellent temperature ramping and at the same time effectively maintained temperature stability within the user-defined parameters. The platen’s temperature range relies on the technique of heating and cooling, including LN2 that cools down to -60°C and heating that raises temperature to as high as 150°C.
Angstrom’s engineers have designed a space simulation equipment using the right pressure and temperature controls. Using the preferred pumping system, data monitoring and thermal control options, the company’s system is touted to be one of the most sophisticated space simulation solutions available in the market today.
The entire components utilized for producing space simulation equipment have been tested and shown to be reliable. Angstrom’s space 3-1fluid circulating systems, pumping systems, and vacuum vessels have undergone stringent testing. The company’s space simulation system allows engineers to test components in high vacuum conditions using different options available for pressure and temperature controls, while ensuring reduced operations costs.
Angstrom Engineering provides the optimum design and deployment of space simulation equipment in the field. The company’s engineers can work with various sizes for specific simulations and can easily moderate all pressure controls according to customers’ unique application needs. Powered systems can be utilized in the simulator, and other environmental tests can also be carried out, such as light spectrum emitters, x-rays, and devices that emit different frequencies of electromagnetic radiation.
According to partners who utilize Angstrom’s space simulation systems, the systems are affordably priced and are better in almost every way when compared to other simulators available on the market. Angstrom is proud that its space simulation systems are used for testing the equipment that is currently being used in space.
