What Makes Lagrange Points Special Locations In Space -

Lagrange points are categorized by their level of stability, which dictates how much fuel a spacecraft needs to stay in place. The Unstable Points (L1, L2, L3)

At any given point in space near two massive bodies, an object is typically pulled toward one or the other. Lagrange points are the five specific locations where these competing pulls cancel each other out.

stationed at L1 and L2 (JWST, Gaia, DSCOVR)

These points are like the peak of a hill. A spacecraft can stay there, but any slight nudge will cause it to drift away. To remain in these locations, satellites perform "station-keeping" maneuvers, often orbiting the empty point in space (known as a Halo orbit). The Stable Points (L4, L5)

They allow satellites to stay in a fixed position relative to the Earth and Sun, simplifying communication and data collection.

Located directly between the two large masses. It offers an uninterrupted view of the Sun, making it ideal for solar observatories like SOHO.
