My kitty, Keelor, is still going strong at 17 (knock on wood). He came from a litter of four, one of whom died when he was only a few months old. His sister was euthanized just last year at 16, but his other brother died at a relatively young age (around 10, if I remember correctly) from necrotizing pancreatitis.
X-band radio waves used by the rover to communicate. The rover communicates with the orbiters and the DSN through radio waves. They communicate with each other through X-band, which are radio waves at a much higher frequency than radio waves used for FM stations. Credit: NASA/JPL-Caltech.
