Galactic cosmic rays (GCRs) pose a particular challenge as they are not easily shielded and have dose rates as high as 0.5 mGy/day. Sustained irradiation to the central nervous system is a major concern, both for long-term astronaut health and overall mission success. Studies in rodents have...
Above, cosmic rays are highlighted with white circles, and appear red. Occasionally, a star will oversaturate pixels on a camera’s detector. As a result, when Webb takes additional images with the same filter, the star’s appearance persists across several frames. For example, in Webb’s ...
you are CORRECT. It is one reason why ECC memory has been developed. In the unlikely event that a Cosmic Ray hits a stick of RAM, it may flip some of the “1”s to “0”s and vice-versa. ECC Memory works sort of like RAID 5 so that a hash is created for each piece of memor...
