What does Jason tell Tyler about the Martian ambassador, conditions on Mars and why he was sent?

Even though the Martian civilization had made great advances in terms of biotechnology, it was relying on the limited resources available on the planet. These resources were rapidly vanishing, so the Martians devised the replicators technology to scan the universe for more resources. However, they were unable to launch the replicators they designed, which is why Wun was sent to Earth.
