https://www.smithsonianmag.com/smart-news/nasas-voyager-1-is-glitching-sending-nonsense-from-interstellar-space-180983448/ This spacecraft was launched when I was in Pre University 2 in Raffles Institution. It is a testimony to the engineering (frugal and with deliberate redundancy) that both Voyager spacecrafts are sending back data and now from outside the heliosphere. Did not realise that the Voyager's computers have only 70 kb of RAM!!!!
