If it were up to Lujendra "Luju" Ojha, he might be killing it on guitar in his old Death Metal Band today. Instead, he was in France for a fellowship when he called in to a much-hyped NASA press conference to share his historic finding of flowing liquid salt water on Mars. If you get Ojha's voice mail, the recording tells you in a comic drawl that he might call you back, "or maybe not." Ojha is perhaps the latest in a growing list of young space scientists like Bobak "NASA Mohawk Guy" Ferdowsi who are breaking the mold of your grandpa's stereotypical buttoned-down, clean-shaven, pocket protector-wearing scientists. When Ojha returns my call shortly after I leave a message on his cell phone, he's quick to clarify that he doesn't consider himself an astrobiologist or a planetary scientist. That's not just because he's only 25 years old and still technically in graduate school, pursuing a Ph.D. at Georgia Tech, but because he sees himself more as a "jack of all trades" as far as science goes. He also spends a lot of time studying earthquakes on our own planet, for example. He walks me through how he devised a new technique to analyze photos from the Mars Reconnaissance Orbiter (MRO) and wound up finding evidence of water mixing with salts. After that, I can't help asking about a photo on his personal website -- it shows Ojha in long hair, guitar in hand, microphone in front of his mouth, belting it out with his old death metal band.
