space telescope James Webb makes history 1.5 million kilometers from Earth, and does it with a much smaller hard drive than you might think: just SSD from 68 GB.
In accordance with IEEE Spectrum, the $10 billion telescope has little memory because its survival is more important than its capabilities.
James Webb’s SSD memory is smaller than your PC
Memory SSD the one chosen for the mission is special because it must operate in extreme conditions, such as temperatures close to absolute zero. For this reason, it retains special survival characteristics, in addition to radiation protection.
James Webb it can transmit data to Earth at 28 Mbps via the Ka band at 25.9 GHz, which operates with a planet-wide deep space network. Unlike Hubble, it can send more information to the planet.
The probe sends 28.6 GB of scientific data in two windows per day, so 68 GB of space is enough to collect 24 hours of images and send them without being stored in the telescope.
The communication of the probe with the Earth includes an acknowledgment protocol: only after James Webb receive confirmation that the file was successfully received, it will proceed and delete its copy of the data to free up space.
It will make it worse
POT It is estimated that only 60GB of storage will be available at the end of the device’s 10-year lifespan. James Webb due to wear and tear and radiation, and 3% of the drive is used to store engineering and telemetry data.
This will leave the telescope with very little room for urgency, which makes us wonder if its lifetime will be anywhere near that of Hubble, which will still be strong after 32 years.
