An amazing bit of long-term planning today's landing on Comet 67P/two complicated Russian names who first spotted the comet 45 years ago.
The science, engineering and mathematics are staggering including the Irish involvement - Captec and Maynooth.
Will they find complex hydrocarbons? The story seems to be comets brought molecules that are the foundation of life to Earth - but where did the comets get them from in the first place?
That piece of tech will sit on that comet perhaps for millions of years unless the comet burns up flying to close to the sun over the next year.
