The location of L 1 is the solution to the following equation, gravitation providing the centripetal force: = (+) + where r is the distance of the L 1 point from the smaller object, R is the distance between the two main objects, and M 1 and M 2 are the masses of the large and small object, respectively.
Aditya-L1 was successfully launched on 2 September 2023 and entered the halo orbit around the lagrange point on 6 January 2024. [6] It's a Solar observation mission by ISRO . It will study solar atmosphere, solar magnetic storms , and their impact on the environment around the Earth.
Aditya-L1, following a flight duration of 63 minutes and 20 seconds, achieved a successful injection into an elliptical orbit around the Earth at 12:54 IST. [32] Aditya-L1 underwent a series of four Earth-bound orbital maneuvres prior to its injection to a transfer orbit towards the Lagrange point (L1). It reached its designated orbit at the L1 ...
Along with Aditya-L1, Wind, Advanced Composition Explorer (ACE), and Deep Space Climate Observatory (DSCOVR), SOHO is one of five spacecraft in the vicinity of the Earth–Sun L1 point, a point of gravitational balance located approximately 0.99 astronomical unit (AU) from the Sun and 0.01 AU from the Earth.
Space Weather Follow On-Lagrange 1 (SWFO-L1) is a future spacecraft mission planned to monitor signs of solar storms, which may pose harm to Earth's telecommunication network. The spacecraft will be operated by the National Oceanic and Atmospheric Administration (NOAA), with launch scheduled for no earlier than September 2025. [ 1 ]
DSCOVR takes full-Earth pictures about every two hours and is able to process them faster than other Earth observation satellites. [23] The spacecraft is in a looping halo orbit around the Sun-Earth Lagrange point L1 in a six-month period, with a spacecraft–Earth–Sun angle varying from 4° to 15°. [24] [25]

India's space agency ISRO launched Aditya-L1 to study the sun from a halo orbit around L 1 point. [11] On 6 January 2024, Aditya-L1 spacecraft, India's first solar mission, has successfully entered its final orbit with a period of approximately 180 days around the first Sun-Earth Lagrangian point (L1), approximately 1.5 million kilometers from ...
