  As far as we currently know, the only life or intelligence in the universe is all located on Earth.  
  Would be nice to see some headed far away.  However, we don't really have the tech to do that now.
  I am exploring the idea of sending some machines with AI (no biological life) on a mission to land 
  on an interestellar asteroid that was passing through our solar system.   
  There have been 2 interstellar asteroids that we know of that pass through our solar system in the last decade.
  As we get better telescopes I expect we will see interstellar asteroids even more often. 
  The idea is that it could start out with technology not much more advanced than current levels so
  we could launch reasonably soon and have more advanced tech over time with communications from Earth.  
  
  They could start out with some 3D printers and
  some ability to mine the asteroid with power coming from an RTG.   They could set up a big antenna
  to get higher speed communications back to Earth.   There is plenty of mass on the 
  asteroid to make a very well shielded home in the asteroid so that radiation did not damage them too much.   
  
  They would start out with some spare parts for things that they could not make from the 
  asteroid material to begin with, like computer chips.  But over time as tech advanced they 
  would eventually be able to make all the parts for any of the machines.  So they could 
  keep on building an replacing parts.
  With power, data scrubbing, and spare parts, the machines could survice for thousands of years.
