The Virtual Field Trip, a desktop virtual reality tool developed in partnership between NASA and Macquarie University, enables users to join a group of thirty international scientists interested in viewing and interpreting what may be the earliest well-preserved evidence of life on Earth. Understanding our own origins is key to searching for life, past or present, on other worlds - in particular Mars.

The Virtual Field Trip tool links to other tools in the suite, including Virtual Lab, which allows you to examine a stromatolite with a virtual microscope, and a comparative tool called What's the Difference?, which allows comparisons to be made between modern and ancient environments on Earth and Mars.
