Kepler is back in operation after a ten day rest to safe the mission.

Kepler is back in operation after a ten day rest to save the mission.

When Kepler launched in March 2009, it had four reaction wheels — three for immediate use, and one spare. But one wheel (known as number two) failed in July 2012, so a major problem with the currently glitchy wheel (called number four) could spell the end of the $600 million Kepler mission. It’s unknown at the moment if the 10-day rest period will bring wheel number four back into line. “Over the next month, the engineering team will review the performance of reaction wheel #4 before, during and after the safe mode to determine the efficacy of the rest operation,” Hunter wrote.

Norwegian scientists admit that the climate has shown no warming since 2000.

Norwegian scientists admit that the climate has shown no warming since 2000.

They then spend a lot of time trying to explain this — and failing — in the context of the theory of global warming. The bottom line remains, however. All the predictions and models of the global warming advocates have been shown to be wrong. Carbon dioxide in the atmosphere has continued to rise, without causing any increase in global climate temperature.

Or to put it plainly: We don’t know what’s going on.

An appeals court has unanimously decided that Barack Obama violated the Constitution when he tried to make appointments to the NLRB when the Senate was not in recess.

The law is such an inconvenient thing: An appeals court has unanimously decided that Barack Obama violated the Constitution when he tried to make appointments to the NLRB when the Senate was not in recess.

The Constitution is very clear on this issue (see article I, section 5). It is up to the Senate to decide when it is in recess, not the President. Obama’s attempt to ignore the clear words of the Constitution here is an ugly example of his willingness to place himself above the law, something no American citizen of either party should take lightly.

The seasons change on Mars.

The seasons change on Mars.

With three years of data in hand the researchers report on the sequence and variety of changes that take place over the spring, including outbursts of gas carrying sand, polygonal cracking of the ice on the dunes, sandfalls down the slipface of the dunes, and dark fans of sand propelled out onto the ice. Gas escaping from under the seasonal layer of dry ice erodes channels in the dunes, reminiscent of the erosion that carves more permanent “spider” channels in the southern hemisphere polar region.
