Countdown For Cassini, Plumes on Enceladus, And The Pale Blue Dot

The Countdown for Cassini nears its end - only a few days now to its 'Grand Finale' , following an epic twenty years of exploration in the Saturnian system, and some truly amazing finds-
as well as releasing the furthest ever man- made probe to land on another world (when Huygens landed on Titan), Cassini has also relayed a treasure trove of new knowledge about the mysterious gas giant and its moons - eye opening stuff, like the amazing plumes of water on Enceladus - tantalising and interesting enough to have sparked further exploration
The proposed Enceladus Life Finder- ELF mission is a possible contender in 2020 - the other being LIFE, which is intended to bring samples back to Earth - but we all know how that plays out......

Cassini dived through the water plumes on Enceladus in 2015

Not to be out done (by themselves), NASA simultaneously released the news that the Hubble telescope had seen water plumes on Jupiters moon Europa.
The legacy of Cassini will be covered in its final moments, more thoroughly than I can, so I will restrain myself from further outpourings - but I am proud and humbled to see such wonders in the heavens - proof of what can be achieved when humanity sets aside the petty politics and squabbles that consume so much energy.
The final 'swan-song' dive will furnish us with further science, and for that, I am grateful.

It's forty years for the two Voyager craft in space, and with Voyager1 now travellimg outside our solar system (40,000 yrs until the next star) , it's up to New Horizons to clinch the next rendezvous as it fast approaches the mysterious object MU69 - ok, so fast is relative with MU69 penciled in for a flyby in 2019, but in space terms, that's soon.
It also promises to be the closest flypast yet.

The journey of the Voyagers has blazed a trail, forcing us to upgrade our listening capabilities as they get further away, and let's not forget that the Voyager craft also produced the first images of planets in our solar system that were more than fuzzy blobs - and also the famous image of Earth known as the 'pale blue dot', taken by Voyager One in 1990:
