Briefly about… mechanics in space projects

Mechanical side of the success

Designing devices that are supposed to work in space is a series of responsible and wide-ranging activities. Before the finished element is integrated with the rocket, the engineering teams test its operation in various conditions. Which one is the most important? How and if you can check if everything works properly?


What is important in the mechanical aspect of the satellite design? What to focus on? What to look for? What is most important in mechanics in space projects?

The mechanical design of the telescope must meet several requirements. From the basic, allowing the satellite to survive unscathed travel to space and further stages of the mission, to advanced ones, which define the safety of the mission and its trouble-free course.

What requirements should a satellite have?

Characteristic requirements for the reliability of the satellites can be divided into functional and durability.


Functional aspects – these that allow correct operation of the imaging system. These include, among others, mechanical structure – which must be designed so that the themal deformation of the optical system does not affect the quality of imaging.


Durability aspects – to adequately protect the satellite from the effects of rocket launch – loads, accelerations and vibrations. Other mechanical components not related to imaging must also pass these tests.

Integration with rocket

Satellite always must be compatible with rocket, which means that it must fulfil some requirements regarding integration process, dimensions and mass distribution. Structure of the satellite is also very important, because it is not only a place to which all subsystems are attached, but it is also an important part of the thermal design of the whole satellite. It is necessary to design satellite in such way, that single components will not exceed their working temperature ranges.

Let’s check it!

Even though it is very hard to simulate full space conditions, there are tests which allow to check the quality and durability of the designed satellite. Tests in shakers, thermal chamber, vacuum chamber, and also series of EMC tests can confirm if the components/subsystems/whole satellite is ready to work in space. Positive results of such tests opens the final part of the mission preparation – the last integration process. We hope that everybody will achieve that step sooner or later! This is the stage that will verify if you’re capable of developing mechanics in space projects!
