There are quite a few sites out there, such as this one for your Mars question https://en.wikipedia.org/wiki/Mars , that have the answers to your questions. I have found that doing the research myself is the best way to add to my Ken doll collection, I am sure you would find that it will add to your Ken doll collection, too.A job well done in any case.
when he does get to fly off to the moon or mars ,he can stop and grab his roadster ,and be the only guy in space with a car.bragging rights.
Then he's gonna look back and moon us all !
Am I in the right place?
this goes way beyond my Ken!
seriously though, I doubt anyone is going to mars,for anything more than another stop base like the one they will put on the moon, another blue planet much like our own will most likely be discovered in the mean time ,,that is just a theory, much like any other .but seems more realistic.
so much is known here about its atmosphere , you won't mind my asking if it spins on an axis like earth does , how fast,what sort of gravity does it have, can ya take some of that hydrogen, mix it with other gases and make breathable air or water.or Fuel,all of which will be a big necessity , to sustain life,
mind if I hitch a ride,drop me off on venus, if its not too far out of the way,I know a girl there...
As to your "another blue planet" being found assertion, I think that they have already found one. There is a problem with that, though. Into your favorite search engine type "how long would it take to get to the nearest star" and hit return. Please let us know your answer. For your research and a correct answer, you will get a "like" from me.
