KOMPAS.com – Telescope James Webb’s outer space (JWST) has orbited the sun at a fairly close distance of nearly 1 million miles or 1.5 million km from Earth, at around 2 p.m. EST, Monday (24/1/2022).
James Webb Telescope this is designed to give the world a new perspective on the early stages of the creation of the universe.
JWST Observatory Manager at Goddard . Space Flight Center NASA (GSFC) in Greenbelt Maryland Keith Parris said ground operators will drive telescope perfecting the final orbital position of JWST.
For about five minutes, the team pushed the observatory into position without going beyond the goal or the second Lagrange point (L2).
For information, there are five Lagrange points around the earth and the sun.
The object at position L2 is in gravitational equilibrium, where the gravitational pull and centrifugal force of the object’s orbit puts itself in its position.
Launch Live Science, space telescope 10 billion US dollars was launched on December 25, 2021 and finally on January 24, telescope James Webb orbiting near the sun.

JWST Operations Project Scientist Jane Rigby explains, Space Telescope James Webb will make a close orbit of the sun at about L2 every six months, which is known as a halo orbit.
This orbit will keep the telescope in an equal position relative to the earth and the sun, and ensure that the sun will not be obstructed by the earth which could affect the thermal stability of the Webb instrument and hinder its access to solar power.
Rigby added that Webb’s operators will continue to change the telescope’s orbit around L2 by firing its thrusters every 21 days.
With this adjustment, fuel reserves should far exceed the 10 times the mission is performed.
“The Webb telescope may have enough fuel to last 20 years,” Parrish said.
With JWST positioned orbiting L2, the collaborative telescope NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA), will undergo more alignments over the next few months.
This adjustment is in preparation James Webb Space Telescope to carry out scientific observations that will target some of the faintest and most distant objects in the universe.

James Webb Space Telescope Achievements
The James Webb telescope managed to reach another important milestone earlier this month. The telescope opened up an enormous golden mirror, a critical component of keeping its instruments cool while searching for faint signals from the universe.
According to NASA, the giant golden mirror segment opened from its launch position on January 8, 2022.
Over the next three months, scientists will align the main mirror of the James Webb telescope by pointing its 18 mirror segments at a bright isolated star.
Next, align the mirror segment into about 1/5000 of human hair, so that, the mirror segment will act as a single monolithic mirror.
Its predecessor, the Hubble Space Telescope, entered its third decade of taking space pictures from its orbital path around Earth at a distance of about 340 miles or 547 km.
Hubble images continue to provide new insights into the cosmos, recently observing the dwarf galaxy Henize 2-10, which lies about 34 million light-years from Earth.

The results reveal clues that black holes may play a role in star formation.
However, Webb’s infrared apparatus and its much larger main mirror, 21.3 feet (6.5 meters) wide, are the largest ever sent into space.
It will offer an unprecedented view of cosmic objects during the mission.
The James Webb Space Telescope will use infrared to detect faint signals from the universe’s earliest stars and galaxies, and to penetrate the dense dust clouds that blanket star and planet formation.
“Everything we’re doing is setting up the observatory to do transformative science, from exploring the atmospheres of planets orbiting other stars to studying the darkest parts of the sky for signs of first-generation galaxies that formed more than 13.5 billion years ago,” Riby said.
“We’ve been a month and the baby hasn’t even opened his eyes yet, but that’s the science we’re looking forward to,” explains Riby.
