The 608-day trip included a ride to Mars on a space shuttle, travel to the research site, and a recreational day to "float around."
Just in case anyone was apt to fall for such a prank, EarthWatch did give away few tell-tale signs that the expedition wasn't what it seemed. The price tag ($1,250,000) alone should have been a red flag, not to mention the lead researcher listed in the description was "Dr. Marvin Martin of the Intergalactic Science Coalition."
This trip might have been a joke but EarthWatch does offer plenty of legit worldwide journeys that let volunteers engage in scientific field research and education to promote a sustainable environment. For more information, visit http://earthwatch.org.
