Find a habitable planet and start a colony where the only creature are salamanders.

To accomplish this goal, I suggest we invent a rocket that could hold enough fuel to travel to Tau Ceti e, which is an unconfirmed planet 11.9 light-years away. If this suggestions doesn't work, we could travel 20.2 light-years to Gliese 581-d. This would have to be done in a reasonable time, otherwise the salamanders would perish on their journey. On this planet we could land the salamanders. I also suggest having an Astronaut along with them to care for them and release them onto the planet safely. The cost could be extremely high due to the research and actual build cost of the rocket needed for this expedition. If we wait a number of years, a rocket of this caliber would probably be created, and so this expedition would be little cost itself. I am open to suggestions for other animals.
