For instance, Lo has shown that the manifolds surrounding the libration points of the outer planets all intersect.
NASA now has four space missions in the works that will use the gravitational weirdness of libration points for everything from mapping the whisper of radiation left over from the Big Bang to photographing Earth 24 hours a day.
As the moon rotates around Earth, and Earth around the sun, these libration points rotate with them.
While studying at Stanford with John Breakwell, a legendary aeronautical engineer, Farquhar started working out the dynamics of libration points and «halo» orbits — three - dimensional loops around the points — so named because from Earth the orbit would look like a halo around the libration point.
He and his Caltech collaborators have taken to calculating libration points, halo orbits, and their attendant manifolds for all the planets in the solar system.

For instance, a spacecraft nudged off a libration point in one direction might float into space, following the curve of the manifold, while if it went off in another direction, it would float right back to the libration point.
Put a satellite at a libration point and it would appear motionless from Earth, hanging in space as though the laws of gravity had been suspended.

The spacecraft was sent to a halo orbit around a sun — Earth libration point, L1, which sits nearly a million miles into space on a line from Earth toward the sun.
There is nothing visible at a libration point.
Recently, the availability of solar wind parameters and interplanetary magnetic field (IMF) measured outside the magnetosphere (for example, ACE satellite at L1 libration point) made them appropriate for short - term drivers, due to the fact that the travel time from the L1 point (1.5 million km from the Earth) to the magnetosphere is around half an hour.
