This time, the Webb Space Telescope deployed a universal joint antenna assembly, including a high data rate butterfly antenna, to Telescope observations of the early universe were transmitted back to earth < p > figure: NASA announced the successful deployment of the antenna for the Weber space telescope. The circle in the figure is the antenna assembly of the telescope < / P > < p > NASA officials said that this antenna will be used to send scientific data from the observatory, at least 28.6gb each time, twice a day. "The mission team has now launched and tested the movement of the antenna assembly. The whole process took about an hour." < p > the $10 billion Weber space telescope is the largest and most powerful space telescope in history. It aims to study the earliest stars in the universe and other cosmic mysteries < p > in order to successfully carry out the deep space observation mission, it takes a month to make full preparations before and after the launch of the Weber space telescope. The Weber space telescope is currently on a 29 day space trip to L2 Lagrange point 1.6 million kilometers from the earth < p > according to the latest news from NASA, in addition to antenna deployment and testing, the flight controller of Weber space telescope also starts the temperature sensor and strain gauge of the telescope for the first time. These instruments will allow flight controllers to monitor the temperature and structural system status of the Weber space telescope in the coming days < p > for scientists and engineers on mission, accurately detecting the temperature and structural load of Weber telescope is the key, because the most challenging task for this new space telescope is how to unfold the huge sunshade < p > as an infrared Observatory, the prerequisite for the normal operation of Weber space telescope is to maintain a low temperature. To do this, the Weber space telescope will deploy a multi-layer shade the size of a tennis court eight days before launch. The first step in deploying the sunshade is expected to begin on December 28, US Eastern time < p > the next step of the Weber space telescope is to correct the ignition in the middle of the second engine, in order to adjust the maneuvering direction of the telescope towards the L2 Lagrange point. This is the second of the three planned engine ignition, which is expected to be completed later on December 27 Eastern time. (Chen Chen) < / P > < p >
