James Web Space Telescope, which is now fully deployed and continues to progress in its final class as the team reads telescopes for science operations in a few months. This week, the telescope turned on its high-profit antenna, which enables telescope to send data to Earth and get command through NASA's Deep Space Network.
The diagram below shows the major components of the James web, now everything is deployed and the observatory is in its final configuration. The antenna is under binoculars here, the spacecraft is coming out of the bus which is home to essential systems such as electricity, height control and communication.
Along with other parts of the spacecraft, the antenna was tested extensively on the Earth before being ready to use in space. Antenna was released in December last year, exactly one day after the launch of the spacecraft, as part of the gimbal antenna assembly. As NASAThe antenna will be under much more use as it will require at least 28.6GB of science data to be sent twice per day from the web to Earth. The data will be sent via space and will be lifted by NASA's Deep Space Network, which has three places worldwide, so that there is always at least one place that can maintain contact with the web as the Earth's spin.
To send data efficient, webb will send data to a part of an electromagnetic spectrum called radio band. “The team also turned on the high-profit antenna, which enables the decline on Earth through the dark space network using the KA radio band,” NASA wrote This week. “The C-Band provides a much higher data rate than S-Band that the web is still using for communication. The band and high-profit antenna will eventually allow the observatory to send science images and data to the ground for astronomers around the world and to analyze and search the discoveries.”
NASA has also shared that the first target of the web will be Star HD 84406. It is a very bright star – in fact, it will be very bright for the web for studies after focusing on the telescope – but it makes it ideal to collect engineering data during the process of aligning the mirrors of the web.
