With the precise deployment of the James Webb Space Telescope in its final orbit, the Lagrangian point 2 halo orbit is the last step in a month-long journey of this sophisticated and powerful scientific instrument. Success has been achieved to be ready to decipher the mysteries of the universe.
Now the journey of the James Webb Telescope is over, and this Space observatory has successfully taken another important step. After a month of challenging travel, the Web adjusted its precise final circuit as planned with the final stage of turning on the propulsion engines. The circuit is known as the halo or perimeter of Lagrangian point 2.
The last step in turning on the James Webb engine
to accurately position the Sun-Earth L2 halo orbit
L2 is one of the five points of gravitational equilibrium between the Sun and Earth In which the effect of the gravitational forces of the sun and the earth on the spacecraft is neutralized, and James Webb can be in a stable orbit without the need for general propulsion and with minimal fuel. This range also allows the sun, earth, and moon to line up behind the telescope, giving the scientific instrument an unobstructed view of the universe. A single path alternately moves around a point L2 in a set of paths. The Lagrangian Earth series and point 2 orbit the sun at the same rate.
- Where is the James Webb Space Telescope now?
James Webb, in its final state, is oriented toward the outside of the solar system, so the sunshade is facing the sun and perpendicular to it so that the mirrors and scientific instruments of the Web can cool in complete darkness and allow the faintest light in the universe to be observed.

of the James Webb Space Telescope
To enter the L2 halo orbit at a distance of about 1.5 million kilometers. During today's operation, the James Webb Telescope performed the "L2 Insertion Burn" (MCC2) or L2 Insertion Burn, the final step in the Web journey. The operation involved briefly turning on the spacecraft's propulsion engines so that it could accurately navigate the planned halo around point L2.
This process took place at 14:00 Eastern time (10:30 Tehran time). For about 5 minutes (297 seconds) it turned on its internal propulsion to make the final corrections on its route. This increased the speed of the spacecraft by only 1.6 meters per second, which was required to reach point L2.
At its best, James Webb needed less fuel to correct his steps. After separating the observatory from the missile, several partial propulsion steps were performed along the path, including intermediate propulsion 1 (MCC1) so that the observatory could accurately reach its operating circuit. Residual fuel is now used for normal web operations throughout its life, including adjustments to stay in good orbit and counteract the shock of solar radiation on the sun visor.
NASA Director Bill Nelson "Web, welcome home," he said of the end of the web journey. Congratulations to the mission team for all their efforts to ensure the secure entry of the Web to Lagrangian Point 2. "We are one step closer to discovering the mysteries of the universe, and I look forward to seeing the first new web views of the universe in the summer!" And open the human eye to the unknown.
