As our sun gets hotter and boils our oceans in roughly a billion years will Mars and outward bodies be in the perfect position to be in a new 'goldilocks' zone? The sun should still have 4 billion years of life which is enough for a planet to develop a life supporting atmosphere. Is Mars and the moons of outer planets simply too small to hold one?

Could Venus have been in a perfect position once before for water but the sun grew too hot and now it's Earth's turn?

Water is at least plentiful on some of the moons of Saturn and Jupiter.

As for Mars, absolutly yes. It's the only place in the Solar System that can sustain a human civilization with current technology.

 

The moons of Jupiter and Saturn are much more difficult to colonize in the near future.

If we are looking for evidence of past life, why aren't we launching more probes to study Venus? Mars has always been outside what is believed to be the habital zone. It's cold now but would have been much colder before when Venus would have been inside the habital zone. Mars's turn will come but not for another billion years.

I understand the extreme heat and sulphur makes sending anything out there a challenge but looking at the list of future missions there, it doesn't seem like past life is a priority.

Also, if the moons orbit is inching further away from Earth, can't we do anything to make Earths orbit inch away from the sun permanently? A one off event that slowly moves Earth away to keep it permanently in the Suns habital zone? So in 5 billion years we are where Neptune or Pluto is.

Also better to end the life of a planet as a rouge then turn to ashes inside a sun. That way, everything that ever lived is still 'around'.

Nope. During around a billion years, Mars had conditions similar to current Earth (in temperature and humidity). Even more, Mars achieved that conditions before Earth, so there is a real possibility that life on Earth came from Mars.
