They forgot to put some information on the Pioneer plaques. In case you don’t remember, the Pioneer plaques are a pair of gold-anodized aluminium plaques which were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft. The plaques feature a pictorial message, thought to be useful in case the vessels are intercepted by extraterrestrial life. They show the nude figures of a human male and female along with several symbols that are designed to provide information about the origin of the spacecraft. 40 years after take-off, the spacecraft and their plaques are now twice as far from the Sun as Pluto and heading to Taurus.
However, the defining feature of humanity, in my view at least, is missing from the plaques: what are human rights? Hence I’ve made some revisions. If someone wants to send them to ET, feel free. I’m sure he’ll understand. Perhaps some terrestrials could also benefit. I’m looking at you, Assad.
