Voyagers 1 and 2 were, to put it simply, incredible. They were true explorers and unveiled many mysteries of the outer Solar System, revealing the outer planets in all their glory. Communication with Voyager 1 has until recently been possible, slow but possible. More recently however, it has been sending home garbled data rendering communication to all intents impossible although messages can still be sent.
Hubble’s new look at Saturn on 12 September 2021 shows rapid and extreme colour changes in the bands in the planet’s northern hemisphere, where it is now early autumn. The bands have varied throughout Hubble observations in both 2019 and 2020. Hubble’s Saturn image catches the planet following the southern hemisphere’s winter, evident in the lingering blue-ish hue of the south pole.
On the 1 March, the team issued a ‘poke’ command to Voyager which makes the FDS start to vary parameters and sequences in case of a corrupt section of code. The process was developed to safeguard against such occasions. The dump contained everything – hopefully – that the engineers needed to get to the bottom of the problem. It contained program code (which controls spacecraft operations, variables based on spacecraft commands or conditions along with scientific and engineering data too. The team are now focussing their attention on this code, meticulously comparing it with a dump from before the communication problems.
