On our quest to find life beyond Earth, scientists first must have to ask themselves: what signs would be the most compelling evidence?This self-portrait of NASA's Curiosity Mars rover shows the vehicle at the "Big Sky" site, where its drill collected the mission's fifth taste of Mount Sharp. Four antennas of the Atacama Large Millimeter/submillimeter Array (ALMA) gaze up at the star-filled night sky.The scientific search underway for life beyond Earth requires input from many disciplines and fields. Strategies forward have to hear and take in what scientists in those many fields have to say.There are a plethora of journals publishing scientific results relevant to astrobiology. It is important to seek advice from your advisors and colleagues so that you can make an educated choice when publishing your data.

NASA MISSIONSExploring the Red Planet

The rovers and spacecraft we’ve sent to Mars have found evidence the planet was warmer in the past, with lakes and rivers. Was there life there? Future exploration may find evidence for that as well.

The facts and figures —37%

The gravity on Mars is only 37 percent of Earth’s gravity. Not only could you leap three times higher on Mars, but this lower gravity is one reason why Olympus Mons became the biggest volcano in the solar system.
