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.

Not exact matches

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.

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.

As the moon rotates around Earth, and Earth around the sun, these libration points rotate with them.

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.

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.

This is why IPCC forecasts are wrong: They do not take changes in the Earth's orbit into account (only «eccentricity» (not the pendulum swing movements (see Wilipedia: Libration) The Libration forcing increased temps to their 2000 level and from this tipping point on, temps will stay flat for 3 more decades, which can easily and transparently for everyone interested be calculated.....
