Update: No, it's this rock — enhanced by an added black border, I see:
You have to wonder about the mental age of his audience, who apparently didn't stop to think a) How Hoagland knew it was a Nike, or b) WTF a sneaker of any kind would be doing on Mars, where they don't play basketball or even tennis.
However, the primary sujet du jour was not sports footwear, but methane.
If only he'd stopped there, we could all have gone back to sleep a little wiser. But no, he had to spoil it in the second hour by proposing a third possible methane theory—namely, that the gas was periodically oozing out of the long-buried rotting remains of the Great Martian Civilization that built the Face at Owen Mesa before being obliterated by a planet-busting impact 65 million years ago. That, of course, has no chance whatever of being the correct explanation because if there were such a civilization, there would be plentiful other remnants of it to examine. And I don't mean Nike sneakers.
The man's mind simply doesn't work like yours and mine. He says that NASA statements at press conferences are coded—"You have to know how to read between the lines"2 (in other words, the statements can mean whatever he wishes they meant.) Last night's runaway prize-winner for zaniness was "We're dealing here with two separate missions, one all about the usual geology and the other about the technology of the ancient civilization" (not a verbatim quote but close). The image of a duplicate "mission control" full of Hoagland clones gasping as the next Nike sneaker comes into view had me guffawing into my pillow.
2] He didn't say that last night. He said it about a JPL press conference on Vesta, which I blogged about at the time.
