New Horizons Mission to Pluto

Juno next year for Jupiter.
Yep - should be interesting, but just a shame it's mission profile is so limited (focussed almost entirely on Jupiter itself). Jupiter's moons are so varied and potentially game changing (with regards to life elsewhere in the universe). It would be nice to have a Cassini style mission to Jupiter.

ESA has one planned, although won't get there until 2030, so probably best not to wait up!Jupiter's moons are so varied and potentially game changing (with regards to life elsewhere in the universe). It would be nice to have a Cassini style mission to Jupiter.

I could almost cry when I see what brilliance man is capable of and compare it to the horrors he can also inflict.
How poetic. Very well written.I read that Horizons, once into Interstellar space, will effectively last forever? There isnt anything which can decay/erode/damage it out there so it will likely outlast us and even things like the Earth itself? Staggering to think of if true.
Like the two much older Voyagers before it and a number of other space probes and rovers, New Horizons is powered by a nuclear Radioisotope Thermoelectric Generator (RTG). This uses the heat released by the decay of Plutonium to generate electricity. RTGs can supply power for decades. Voyagers 1 and 2 are still working after 38 years in space.

Interestingly one of Cassini's back up RTG is used on New Horizons.
AFAIK That is because they aren't making those RTG's anymore.New Horizons eventual fate (along with Voyagers, Pioneers and various other bits, including the 3rd stages that sent all of the above en-route) will probably be the last existing bits of humanity. It seems improbably that we're work out how to become an interstellar civilisation before we either use up the Earth or the Sun swallows it... bit melancholy perhaps but I can visualise New Horizons sailing on silently for billions of years after the Sun blows our solar system to dust.
Perhaps if more people grasped the tenuous, temporary nature of our existence and the vastness into which NH and Voyager etc are dispatched into they might act with a bit more thought... no actually they wouldn't because people are generically selfish a*seholes :-)
