The satellites must maintain that distance with an accuracy down to a single millimeter to pull off the mission.
ESAs Frederic Teston said in astatement.
But that would have required a larger budget; Proba-3 is considered a low-cost mission, according to ESA.
Why do we study the Suns corona?
The corona is a million times fainter than the Sun.
What are the Proba missions?
The low-cost, small satellite missions seek to test new technologies and concepts in spaceflight.
ESA has launched three other Proba missions thus far, with one currently observing the Sun.
Similarly, Proba-3 has an expected lifespan of two years.
For a technology demonstration mission, the team has high hopes for the pair of tiny spacecraft.
But the real-life design will truly deliver excellent science.
