IMAP currently is scheduled to launch in October 2024 to orbit a point between Earth and the Sun known as the first Lagrangian point
, or L1.
Themain idea behind the Lagrangian particle-based approach is to use a judiciously selected ensemble of Lagrangian point
particles, often called superdroplets or superparticles, to represent the enormous number of aerosol, cloud, and precipitation particles typically present inside the grid cell of a cloud model.
Once it launches, the 6.5-meter near-infrared telescope will orbit the Sun at the Lagrangian point
L2, 1.5 million km farther out than Earth.
The Earth-moon (https://en.wikipedia.org/wiki/Lagrangian_point) Lagrangian Point
1 (L1) is a point in space about 85 percent of the way from Earth to the moon, where the force of Earth's gravity would exactly equal the force of the moon's gravity pulling in the other direction.
Similar to GPS, a high-precision satellite navigation constellation which consists of libration point satellites in the Earth-Moon system is introduced to provide navigation information for deep space probes, which can be called, accordingly, the Lagrangian point
satellite navigation system.
Gaia will operate from a stable location 1.5 million kilometres from the Earth known as the L2 Lagrangian point
Gaia will map the stars from an orbit around the Sun, near a location some 1.5 million km beyond Earth's orbit known as the L2 Lagrangian point
Martin Connors of Athabasca University in Canada and colleagues Paul Wiegert and Christian Veillet used observations made in late April this year with the 3.6m Canada-France-Hawaii Telescope on Mauna Kea to identify 2010 [TK.sub.7] as a Trojan object, one which currently circulates around the [L.sub.4] Lagrangian point
, thereby leading the Earth in its orbit around the Sun.
Herschel, which relies on infrared light to peer into the universe, should reach its final orbit in November around a point in space known as the second Lagrangian point
, which astronomers generally refer to as L2.
Satellites, (located upstream at the L1 Lagrangian point
--where the Earth's and the sun's gravity cancel each other), monitoring the solar wind can yield predictions up to an hour in advance.
Michael Mann's film Ali explores the complexities of life in a Lagrangian point
, with forces pulling him between champion boxer and cultural icon.
