RAW files and videos taken on a modest DSLR or mirrorless camera still take up quite a lot of space. So, how much storage space do you think James Webb Space Telescope needs? One would think that a ten-billion space telescope would need quite a lot of storage space for all those super-sharp and detailed photos it takes and sends back to Earth. If that’s what you think – you’re wrong.
The JWST uses memory that’s likely smaller than your smallest SSD, or even memory card – it has only 68 GB of space! But how? Why? NASA has explained how it works and why a telescope that powerful doesn’t need a lot of storage space at all.
