2013 NSF GRFP awardee Lujendra Ojha led a study that suggests there is liquid water on Mars.
A new study led by scientists at the Georgia Institute of Technology provides the strongest evidence yet that there is intermittent flowing liquid water on modern Mars. Using instruments on board NASA’s Mars Reconnaissance Orbiter (MRO), researchers measured spectral signatures of hydrated minerals on slopes where mysterious, possibly water-related streaks are found on the red planet. These streaks, known as recurring slope lineae (RSL), form and snake down the planet’s steep slopes during warm seasons when temperatures exceed -10 degrees Fahrenheit (-23 degrees Celsius). They disappear at colder times during the Martian year.
