Sensor (astronomy)

Sensor (astronomy)

It is a technical device that, in a way, serves to extend people's senses in space.

In practice, a space sensor, mounted on a space probe or on an spaceship, has the power to determine the presence of natural objects, or built by humans, capturing the energy they emit. This energy can obviously be found in various forms: nuclear, electromagnetic (the latter can include both the visible portion of the spectrum and the invisible), chemical, biological, mechanical, thermal, etc.

In addition to their scientific research function, the sensors play an important role as guidance bodies for spacecraft. In this case, its function is to search and fix with a special eye the light of a star or a planet, in this way an orientation system is achieved that the space vehicle can use on its trip.
