NASA’s James Webb Space Telescope has just reached its final destination, around a point in space with special gravitational properties known as the second Lagrange point, or L2. The $10 billion observatory could spend 20 years or more there, peering into deep space and gaining unprecedented insights into the Universe.
Instead, the James Webb Telescope faces away from the Sun and always has our star, Earth, and Moon behind it.
“L2 is great because the brightest objects – the Sun, Earth, and Moon – are on the same side of the spacecraft,” says Karen Richon, an engineer who leads the James Webb Telescope Flight Dynamics team at the Center for Astronomy.
