The mission encountered many hurdles and delays due to the extraordinary challenges owing to the JWST&#8217;s enormous size and operating temperature.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">The Webb telescope started its journey away from the Earth to reach the orbit of the second Lagrange point (L2), approximately 1.5 million kilometers (1 million miles) away.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">L2 is a location in space where the gravitational forces of the Sun and Earth are balanced by the orbital motion required for a spacecraft to move with them. This position also reduces the fuel needed for a spacecraft to remain in position. In addition, orbiting in L2 will keep the telescope protected from the light and heat of the Sun and Earth (and Moon) and allows for continuous communications with Earth.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/polscienceweb.com\/wp-content\/uploads\/2021\/12\/Lagrange-L2-1.png\" alt=\"Lagrange L2\" class=\"wp-image-6832\" width=\"470\" height=\"411\" srcset=\"https:\/\/polscienceweb.com\/wp-content\/uploads\/2021\/12\/Lagrange-L2-1.png 549w, https:\/\/polscienceweb.com\/wp-content\/uploads\/2021\/12\/Lagrange-L2-1-300x262.png 300w\" sizes=\"(max-width: 470px) 100vw, 470px\" \/><figcaption>L2 position will allow the Webb telescope to stay in a fixed position relative to the Earth and sun<\/figcaption><\/figure><\/div>\n\n\n\n<div style=\"height:5px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">It will take Webb about a month to reach L2. During this time, it will undergo unfolding, telescope deployment, cooldown, instrument turn-on, and finally insertion into L2 orbit. In the following months, up to 6 months, it will undergo other system checks and calibrations after which it finally begin its scientific observations.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">Watch here to view the animation of The James Webb Space Telescope&#8217;s Orbit.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"epyt-video-wrapper\"><iframe  id=\"_ytid_99970\"  width=\"1170\" height=\"658\"  data-origwidth=\"1170\" data-origheight=\"658\"  data-relstop=\"1\" src=\"https:\/\/www.youtube.com\/embed\/6cUe4oMk69E?enablejsapi=1&#038;list=TLGG8tIphgpDAHkyNjEyMjAyMQ&#038;autoplay=0&#038;cc_load_policy=0&#038;cc_lang_pref=&#038;iv_load_policy=1&#038;loop=0&#038;rel=0&#038;fs=1&#038;playsinline=0&#038;autohide=2&#038;theme=dark&#038;color=red&#038;controls=1&#038;disablekb=0&#038;\" class=\"__youtube_prefs__  epyt-is-override  no-lazyload\" title=\"YouTube player\"  allow=\"fullscreen; accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen data-no-lazy=\"1\" data-skipgform_ajax_framebjll=\"\"><\/iframe><\/div>\n<\/div><\/figure>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">Webb is the scientific successor to Hubble.

Webb will capture images of the universe 13.5 billion years ago, a few million years after the big bang.
