It was originally scheduled to launch in 2007, but the launch was delayed for years due to issues, improvements, and updates. James Webb Space TelescopeIt was launched into space on December 25, 2021. Recently, the first color images of the telescope were also shared by NASA.

The James Webb Space Telescope took these photos. How did he send it to Earth? Telescope, taking pictures Where was it stored before it was shipped? Let’s take a look at the answers to these questions that may surprise many of you.

How is data sent?

• The James Webb Space Telescope, the L2 point and other Lagrangian points.

Contrary to your expectations, the James Webb Space Telescope is not state-of-the-art in all respects. Although of course the telescope contains the latest and even the first used technologies in some of its technologies, well-known technologies for long-term durability and reliability being heard.

The telescope, which is located 1.5 million kilometers from Earth, sends the pictures taken out into the world.ka band‘ frequencies. According to Michael Menzel, James Webb’s mission systems engineer, the telescope is shooting over the 25.9 gigahertz channel. It can transmit 28 megabytes of data per second.

In addition to this main frequency, the telescope provides data transmission from both channels in the S band. While one of these channels is 2.09 GHz, 16 kilobits per second of data transfer can be provided over the channel. The second channel, the 2.27 GHz channel, can transmit 40 kilobits of data per second. This channel is often used to monitor the operational status of the telescope and the health of the systems. to obtain information about the status of the telescope. is used.

Many vehicles such as the James Webb Space Telescope, the Parker Solar spacecraft, the Transiting Exoplanet Survey Antenna, and the Voyager spacecraft are attached to the ‘Deep Space Network (DSN – Deep Space Network)‘ is connected to the network. This network is kept alive with antennas placed in three locations around the world: Australia, Spain and California.

Of course, the telescope is not connected to Earth 24/7, but where does it store its data without sending it to Earth?

According to the information shared, James Webb surprises many of you, It only fits a 68 GB SSD. 3% of this storage is reserved for engineering and telemetry data. In addition, the total storage space is expected to decrease to 60 GB in the next 10 years due to radiation damage in space.

Of course, the data obtained from the depth of space does not stay in the 68 GB SSD for long. Because the storage area is large enough to store the obtained data in just 24 hours. The James Webb Space Telescope, on the other hand, transmits the data it acquires to Earth at certain intervals during the day and removes it from the storage area.

James Webb Space Telescope, 57 GB of data per day While you can get this value at Hubble It was only 2GB.
