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.

ROLL CALL: Signs Point Against Cummings Running for Senate.

Rep. Elijah E. Cummings, who has been considering entering the Democratic race for Maryland’s open U.S. Senate seat, said he will reveal his plans for 2016 during a three-stop tour that could come in “maybe less than two weeks.”

Cummings revealed his plans on Tuesday, just a few hours before Baltimore Rev. Jamal H. Bryant — who was seen by some as perhaps the toughest Democratic primary opponent in the 10-term lawmaker’s career — said he would drop his own campaign for the 7th District seat.

Martha McKenna, a Baltimore-based Democratic operative, said the “tea leaves” point toward Cummings staying out of the race to replace retiring Sen. Barbara A. Mikulski to focus instead on his own re-election and representing Baltimore.

“Bryant dropping out says a lot,” said Martha McKenna, a Baltimore-based Democratic operative.

Bryant, who leads a church of 12,000, told the Baltimore Sun on Tuesday night, “I believe the continued stewardship of my church is my highest calling.”

Another sign? Cummings told reporters in Baltimore he would make his intentions clear during stops in Baltimore City, Baltimore County and Howard County — all parts of the 7th District he represents.

When asked Tuesday what should be read into his those plans and whether they meant he had decided one way or the other on the Senate seat, Cummings — who has been coy about the subject for months now — hedged again: “You never know,” he said.

He’s bad in the House, he’d be bad in the Senate.

INSOMNIA THEATER (JARED POLIS EDITION): As devoted readers know, both Glenn and I posted a little while back about Colorado Rep. Jared Polis’ so-called “apology” for suggesting that college students accused of sexual assault should be expelled even if they are innocent.

Since then, Polis’ halfhearted mea culpa has only continued to generate criticism for its defense of dangerous ideas about students’ rights to due process. The Daily Camera, Polis’ hometown newspaper, published several responses to his apology, even devoting a whole page of its September 19 print edition to the topic.

FIRE’s Joe Cohn wrote his own retort in The Daily Camera, arguing that “By insisting that college administrators adjudicate serious felonies, Polis doubles down on a failed policy that threatens students nationwide.” And if you haven’t seen it already, or if you just want to reassure your memory that “someone really said that,” please watch the video of Polis’ now-infamous remarks and share with a friend.

JOHN PODHORETZ: Pope Francis is just another liberal political pundit.

Pope Francis is unquestionably a man of ­uncommon personal grace, the possessor of a genuinely beautiful soul. “On Heaven and Earth,” his book-length exchange with Rabbi Abraham Skorka first published in 2010, is a remarkable testament to the breadth of his perspective.

But that’s not exactly the guy who showed up Friday at the United Nations. That pope endorsed the Iran deal, the UN’s environmentalist goals and what amounts to a worldwide open-borders policy on refugees — and ­offered a very specific view of how to promote development in the Third World that’s straight out of a left-wing textbook.

I guess that’s why liberal political pundits love him.

KEN WHITE: A Few Comments on the UN Broadband Commission’s “Cyber Violence Against Women And Girls” Report.

I don’t trust the UN on free speech issues. You shouldn’t either. In a world where Iran wins a seat on the UN’s Commission on the Status of Women, people who care about women’s rights should also be skeptical. Pro-censorship forces continually pressure the UN for international laws and norms restricting speech — for instance by demanding laws outlawing blasphemy. Allow me some unabashed American exceptionalism: that’s a bad thing. The United States’ vigorous approach to protecting free speech and rejecting blasphemy laws is good, and foreign norms that encourage blasphemy laws often used to persecute religious and ethnic minorities are bad.

My take: “Cyber Violence” is not real violence. People who want you to conflate online misbehavior with physical attacks have an agenda, and it’s a bad one.
