WebThe Earth moves at 30 km/s so from an orbit the same as Earth's you would need a 6 km/s impulse. But it takes 11 km/s to escape the Earth's gravitational pull from LEO, so you really need only sqrt (11 2 + 6 2 ) speed from LEO. That's 12.7 km/s, and since you're already going 7.8 km/s in LEO, you need a 4.9 km/s impulse.

Sun–Earth L 2 is a good spot for space-based observatories. Because an object around L 2 will maintain the same relative position with respect to the Sun and Earth, shielding and calibration are much simpler.

WebJan 21, 2024 · At Sun-Earth L2, the Sun and Earth (and Moon, too) are always on one side of space, allowing Webb to keep its telescope optics and instruments perpetually shaded. This enables them to get cold for infrared sensitivity, yet still access nearly half the sky at any given moment for observations. Sun–Earth L1 is suited for making observations of the Sun–Earth system. Objects here are never shadowed by Earth or the Moon and, if observing Earth, always view the sunlit hemisphere. The first mission of this type was the 1978 International Sun Earth Explorer 3 (ISEE-3) mission used as an interplanetary early warning storm monitor for solar disturbances.
