It will be positioned near the second Lagrange point
(L2) of the Earth-Sun system.
These structures would hover around Earth at the Lagrange point
- the altitude at which the Moon and Earth exert equal-but-opposite gravitational forces.
Then finally, on Saturday the Russian space agency successfully launched it out of Earth's orbit and onto the (https://solarsystem.nasa.gov/resources/754/what-is-a-lagrange-point/) L2 Lagrange point
Roscosmos said the telescope, named Spektr-RG, was delivered into a parking orbit before a final burn Saturday that kicked the spacecraft out of Earth's orbit and on to its final destination: the L2 Lagrange point
, according to the Associated Press (AP).
Spektr-RG will next navigate to a stable orbit in space called a Lagrange point
(specifically, L2), where the gravitational forces of two large objects -- in this case, the sun and the Earth -- balance each other out.
As per the observatory's schedule, Spektr-RG will cruise to the Lagrange Point
2 located 1.5 million kilometres from Earth before beginning a 4-year all sky survey.
The SPICA Observatory will be launched on an H3 rocket for a nominal mission of 3 years orbiting the second Lagrange point
of the SunEarth system (SEL2).
The story begins at L1 Lagrange Point
, the 'neutral gravity point' where the pull of the sun equals that of our planet.
The so-called Lagrange Point
, also known as L1 appears to be the best.
NASA Planetary Science Division director Jim Green stated that a powerful magnetic bipole placed at Mars' L1 Lagrange Point
could deflect solar winds.
DSCOVR recently reached its station about a million miles away between the Earth and the sun at a Lagrange point
, where gravitational fields of Earth and Sun cancel out.
DSCOVR will travel to the so-called Lagrange point
, or L1, a spot 1 million miles from Earth and 92 million miles from the sun, where the gravity fields are neutralized.
