No go: Falcon 9 aborted its launch tonight at 4:55 am (Eastern) at T minus zero seconds.

Just after ignition there was a shutdown. They were able to make the vehicle safe, and are trying to figure out what happened. It appears there was a high pressure reading in one engine.

The next opportunity to launch is three days hence, though whether they will go for it then depends on whether they can figure out what caused the shutdown.

Update: More details here.

Pitiful: Only 65% of the political class and only 61% of Democrats are aware that federal spending has gone up in the past ten years.

Interestingly, 85% of the general public knows this basic fact, which might explain why the intellectual elites of our country — from both parties — are continually being blindsided by the rise of the tea party movement and its continued success in elections.

Based on further analysis of the data from WISE, the infrared space telescope, astronomers have now made a better estimate of the population of potentially hazardous asteroids.

Potentially hazardous asteroids, or PHAs, are a subset of the larger group of near-Earth asteroids. The PHAs have the closest orbits to Earth’s, coming within five million miles (about eight million kilometers), and they are big enough to survive passing through Earth’s atmosphere and cause damage on a regional, or greater, scale.

The new results come from the asteroid-hunting portion of the WISE mission, called NEOWISE. The project sampled 107 PHAs to make predictions about the entire population as a whole. Findings indicate there are roughly 4,700 PHAs, plus or minus 1,500, with diameters larger than 330 feet (about 100 meters). So far, an estimated 20 to 30 percent of these objects have been found.

Senator Bill Nelson (D-Florida) on Monday attacked the House version of NASA’s budget that required the agency to make a quick decision on its commercial manned launch company.

Senator Bill Nelson (D-Florida) on Monday attacked the House version of NASA’s budget that required the agency to make a quick decision on its commercial manned launch company.

Nelson faces a difficult election campaign from the right. Thus, I suspect he has realized that he is better off promoting free enterprise than local pork. It is unfortunate that the Republicans in the House haven’t yet realized this.
