To follow knowledge like a sinking star

For reals, this time: Voyager 1 has entered interstellar space. In another 300 years it should reach the inner edge of the Oort cloud, assuming there is an Oort cloud; but all instruments will have gone silent by only 2025. Still, ten years of data from the interstellar medium, even at 160 baud, is a lot.

.. but every hour is saved
From that eternal silence, something more,
A bringer of new things; and vile it were
For some three suns to store and hoard myself,
And this grey spirit yearning in desire
To follow knowledge like a sinking star,
Beyond the utmost bound of human thought.

The lights begin to twinkle from the rocks:
The long day wanes: the slow moon climbs: the deep
Moans round with many voices. Come, my friends,
‘Tis not too late to seek a newer world.
Push off, and sitting well in order smite
The sounding furrows; for my purpose holds
To sail beyond the sunset, and the baths
Of all the western stars, until I die.

-Tennyson, “Ulysses”
