On the 40th anniversary of the launch of Voyager 2

"The present life of man upon earth, oh king, seems to me, in comparison with that time which is unknown to us, like to the swift flight of a sparrow through the house wherein you sit at supper in winter, with your ealdormen and thegns, while the fire blazes in the midst, and the hall is warmed, but the wintry storms of rain or snow are raging abroad. The sparrow, flying in at one door and immediately out at another, whilst he is within, is safe from the wintry tempest; but after a short space of fair weather, he immediately vanishes out of your sight, passing from winter into winter again. So this life of man appears for a little while, but of what is to follow or what went before, we know nothing at all."
– Bede, An Ecclesiastic History of the English Church and People (transl. AM Sellars)

On the occasion of the first Human spacecraft exiting the Solar System

Gavotte en Rondeau from BWV 1006, Partita No. 3 in E, one of Carl Sagan’s musical selections for the Voyager Golden Record

Much have I travell’d in the realms of gold, And many goodly states and kingdoms seen; Round many western islands have I been Which bards in fealty to Apollo hold. Oft of one wide expanse had I been told That deep-browed Homer ruled as his demesne; Yet did I never breathe its pure serene Till I heard Chapman speak out loud and bold: Then felt I like some watcher of the skies When a new planet swims into his ken; Or like stout Cortez when with eagle eyes He star’d at the Pacific – and all his men Look’d at each other with a wild surmise — Silent, upon a peak in Darien.

(John Keats)
