SSD Size of James Webb Space Telescope Announced

Have you ever thought about where the James Webb Space Telescope stores and sends data from space to Earth? Let’s explain the details.

It was originally planned to be launched in 2007, but its launch was delayed for years due to problems encountered, improvements and updates. James Webb Space TelescopeIt was launched into space on December 25, 2021. The first color images of the telescope were also shared by NASA recently.

Well, the James Webb Space Telescope took these photos. How did he send it to Earth? Telescope, taking photos Where did it store before shipping? Let’s look at the answers to these questions that have the potential to surprise many of you.

How is data sent?

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

Contrary to your expectations, the James Webb Space Telescope is not state-of-the-art in every sense. Although the telescope, of course, includes the latest and even the first used technologies in some of its technologies, Known-to-last technologies for long-term durability and reliability being heard.

The Telescope, which is 1.5 million kilometers away from the Earth, sends the photos it takes to the world.Ka band‘ frequencies. According to Michael Menzel, James Webb’s mission systems engineer, the telescope is blasting over the 25.9 gigahertz channel. It can send 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 data transfer can be provided over the channel. The second channel, the 2.27 GHz channel, can send 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 being 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 the Earth 24/7, but where does it store the data it obtains without sending it to Earth?

According to the shared information, James Webb, surprising many of you, It only accommodates a 68GB SSD. 3% of this storage is reserved for engineering and telemetry data. Apart from that, the total storage space is expected to decrease to 60 GB in the next 10 years due to the damage caused by radiation in space.

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

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