Comment Slow walking (Score -1, Troll) 59

Not surprising. Obama's activists at NASA have been slow walking (read sabotaging) the program for years. They'd rather be raining federal dollars on their crooked hero Elon MUsk. We need a new President who will make SLS a priority. Constellation was a great program and the leftists wrecked it. Now we are marooned for the next decade on a decrepit space station with our arch enemies, the Russians. Not a space program befitting America, but then again, neither is our leadership.

Comment For comparison (Score -1) 39

For comparison, fluvial landforms of the Atacama have been exposed for about ~23 million years. Channels on Mars have been exposed for 3.5 billion, a huge difference (150x by my count). Even a weak erosive force can accomplish a lot in that time. In that time wind erosion has almost entirely excavated Gale Crater to a depth of more than 5km, leaving Mount Sharp behind at a similar height.

Comment Glacial ice does not fill lava tubes (Score -1) 37

In addition, those western flanks show solid evidence of past glaciers

I know of no instance on earth where glacial ice fills lava tubes. Lava tubes are fragile. Glaciers are very destructive. What plausible process exists where ice will non-destructively fill lava tubes? Earth has thousands of volcanoes and lots of glaciation. Mars has neither. This is a ridiculous statement even for slashdot. The Indian Mars images are impressive, for 1970.
