MARS MYSTERY SOLVED, says NASA.

No further details are available on the nature of the mystery. However, the lineup for the Monday press conference sports top agency authorities, including NASA director of planetary science Jim Green and lead scientist for the Mars Exploration Program Michael Meyer.

The other guests, relatively unknown researchers from American universities, led the science and tech publication Inverse to speculate.

“Our best guess: flowing water, and the potential for alien life,” the publication wrote late Thursday.

That’s because on of NASA’s featured Monday speakers, Georgia Tech grad student Lujendra Ojha, doesn’t quite match the high profile of the NASA leadership hosting the conference. But, Inverse notes, Ojha was responsible in 2011 for the discovery of “possible flows of salt water on Mars.”

According to a 2011 CNN report, native Nepali Ojha used a computer algorithm to remove visual distortions from satellite images of Mars, and notices slim snaky features that moved over time. All he could guess is that they were water.

“There’s going to be years of research put into this to even prove that this is definitely proof of water. And from that, we can move on: OK if this is water, what are the chances that life could be in these kinds of surroundings?” he told CNN.

Most scientists already agree that the canyons and gullies that cover the Martian surface were once carved by water that flowed across the planet’s now-desolate surface. Now the plant’s poles also sport massive caps of frozen water. But one mystery persists: what happened?

Well, perhaps we’ll find out. Related: Why I Hope There’s No Life On Mars.
