For this mission, ISRO is going to spend over Rs 400 crores. If that number seems high, rest assured, that’s not the case — after all, ISRO has a knack of completing its space missions at an abnormally low cost. But why is ISRO placing an observatory at L1 or Lagrange Point 1 in the first place? What is a Lagrange Point There are several points in our solar system, where the gravity of the sun, is equal to the gravity of a planet. These are called Lagrange Points. In total, there are 5 such...
