description Proba-3 Overview
Proba-3 is a European Space Agency technology demonstration mission consisting of two separate spacecraft. These satellites are designed to fly in precise formation to maintain a fixed distance from each other. The Occulter spacecraft blocks the Sun's disk, allowing the Coronagraph spacecraft to observe the solar corona by creating a continuous artificial eclipse.
help Proba-3 FAQ
What is the primary objective of the European Space Agency's Proba-3 mission?
Proba-3 is a technology demonstration mission designed to test precision formation flying in space. It consists of two separate spacecraft that will fly in tandem while maintaining a fixed distance from each other.
How does Proba-3 create an artificial solar eclipse?
The Occulter spacecraft in the mission will block the Sun's disk, allowing the Coronagraph spacecraft to observe the Sun's faint corona. This creates an artificial total solar eclipse lasting up to six hours per orbit.
When is the Proba-3 mission scheduled to launch?
The Proba-3 mission is scheduled to be launched in the mid-2020s aboard an Indian PSLV rocket. The launch has faced a few delays but is targeted to establish a new standard for orbital formation flying.
What orbit will the Proba-3 satellites operate in?
The two spacecraft will operate in a highly elliptical Earth orbit. This specific orbital path allows the satellites to perform their precise formation flying maneuvers in a highly stable, undisturbed environment.
