Reporters reported that Page NARIT National Astronomical Research Institute Published an article by Dr. Tiphon Tangmatitham – Academician of Astronomy. National Astronomical Research Institute stated that on January 25, 2022 at 2:05 am Thailand time James Webb Space Telescope (JWST) has successfully entered orbit at point L2 This is the last step and the end of the installation process.space telescopeThis is the beginning of the process of testing the device before going live in the next 5 months.
James Webb Space Telescope classified asspace telescopebiggest and the most modern today Traveled into space on December 25, 2021 ago.[2] After being in the development process for more than two decades. With the demand for observation in the infrared spectrum, the camera is loaded with technology that is extreme in many ways.
since the control systemtemperature[3] New material for over 6.5 meters of gold-plated beryllium glass.[4] folding and unfolding these devices[5] The mission is to go through 344 complex steps, of which 307 (87%) are classified as single-point failure, where even one mistake will render the entire mission unusable. next
telescopewith sensitivity to light and heat of this size It will not be able to stay in Earth’s orbit where the light from the Earth, Moon and Sun will interfere with observation. Therefore, an orbit is required at point L2, where the centrifugal force is exactly offset by the gravity of the Earth and the Sun.[6] But getting to this point is quite complicated. Because it is a point that is 1.5 million kilometers away in the shadow of the Earth. which is more than four times the distance that any human has ever traveled
before getting to this point JWST It must be sent from the Ariane 5 launch pad to an elliptical orbit from Earth at L2, then three times through the mid-course correction burn. which with the accuracy of the launch of the Ariane 5 rocket into orbit makes JWST Uses less fuel than expected Therefore, there may be enough fuel to extend the total lifespan by more than 20 years (10 years more than previously anticipated).[7]
and when JWST It is at this distance at point L2 that the engine on the JWST will have to run again. By igniting fuel for a total of 5 minutes to change the orbital velocity to 1.6 meters per second. until it changes from an elliptical orbit to an orbit around L2, ending the last mid-course correction burn.
after JWST has been in the target position After this, the next 5 months will be the activation and testing process of the device. And it is expected that we will soon see the first images of the latest tools that will bring humanity together to solve many of the mysteries of the universe. still waiting to be discovered
