Success so far means JWST has enough fuel to extend its science lifetime, NASA say
...away from our planet at a point known as L2. L2 is short hand for the second Lagrange point; one of five so-called areas... – small thruster burns to adjust JWST’s orbit; pointing the telescope toward science targets; and momentum management, which...

A US space strategy for 2050: shaping a domain on the cusp
... term, should develop infrastructure at the Earth-Moon Lagrange Points. The mind is the limiting factor in conceptualising future uses for these points, but, for now, the Earth-Moon Lagrange points are best suited to communications relay and SSA...

Saving Earth – time for a new cooperative framework
... launched once one’s shields are down! Conceptual model (top) of an artificial magneto-shield, which could be deployed at Lagrange Point L-1, developed by NASA Chief Scientist, Dr Jim Green and colleagues. Such a system could also help to prevent the...

LISA Pathfinder – paving the way for future studies of the gravitational universe
...in space. To achieve the required free-fall ‘purity’, an orbit around the Sun-Earth Lagrange point L1 (a virtual point in space known as the Sun-Earth Libration Point 1 - SEL#1) was selected as baseline. This orbit provided an eclipse-free, and hence...
