Q. With reference to Proba-3’s mission, seen in the news recently, consider the following statements:
1.The mission is being led by Russian Federal Space Agency (Roscosmos).
2.It aims to form a 144-m long solar coronagraph, which will create an artificial eclipse, revealing new views of the Sun’s faint corona.
3.It consists of two spacecraft flying in close formation, creating an artificial eclipse.
How many of the statements given above are correct?
Answer: B
Notes:
Explanation –
Statement 1 is incorrect. Proba-3’s mission is being led by European Space Agency (ESA).
Statements 2 and 3 are correct. Proba-3’s objective is to develop technology for precision formation flying and demonstrate the ability to create an artificial eclipse using two satellites. It aims to form a precise formation of two satellites flying in tandem, creating a “flying coronagraph” with a separation distance of 144 meters. The goal is to study the Sun’s corona, the outermost part of its atmosphere. Proba-3 consists of two small satellites, each carrying a set of sensors and instruments, flying in close formation to create an artificial eclipse and study the Sun’s corona.
