https://www.universetoday.com/102785/what-are-lagrange-points/

Of the 5 Lagrange points, only L4 and L5 are stable, i.e. dimples in the gravitational potential landscape, attractive in all three axes. L1, L2, and L3 are attractive in two axes and repulsive in the third, the direction of orbital motion. The gravitational potentials for L1, L2, and L3 are 3-dimensional saddle points.

Once it is at L2, the telescope has to be nudged back into the saddle every 21 days or it will drift away. It has about 10 years' supply of fuel onboard to do this.

I read that once they got parked and checked the tank, they have about 20 years corrective fuel left.
