SpaceX Launches Super-Accurate Next-Gen GPS Satellite for US Air Force

The United States’ venerable Global Positioning System (GPS) is about to get a shot in the arm.
The first advanced, next-generation “GPS III” satellite soared into space today (Dec. 23) atop a two-stage SpaceX Falcon 9 rocket, which launched from Cape Canaveral Air Force Station in Florida at 8:51 a.m. EST (1351 GMT) after nearly a week of delays. The spacecraft, dubbed “Vespucci,” was deployed into medium Earth orbit about 2 hours after liftoff.

SpaceX has launched payloads for the U.S. military before, but Vespucci is the company’s first official “National Security Space” mission — a designation reserved for liftoffs deemed critical to national defense. [See Photos of SpaceX’s GPS III Satellite Launch!]

SpaceX usually attempts to land Falcon 9 first stages shortly after liftoff for future reuse, but that didn’t happen today. The rocket flew in an expendable configuration, without any landing legs, at the request of SpaceX’s customer, the U.S. Air Force.

“There simply was not a performance reserve to meet our requirements and allow for this mission to bring the first stage back,” Walter Lauderdale, mission director at the Air Force’s Space and Missile Systems Center (SMC) Launch Enterprise Systems Directorate, said during a prelaunch call with reporters on Dec. 14.

Rare albino porcupine filmed in Maine woodland


The porcupine was partially camouflaged against the snow.
Hunter and fisherman Greg Strand captured footage of the colorless animal in the woods earlier this month.

The veteran outdoorsman had been walking through the Windham woods just before sundown when he heard an animal approaching and quickly ducked out of sight.

He watched as an adult porcupine emerged from the bushes followed by a juvenile albino.

“I knew it was special,” he said.

“Porcupines usually get a pretty bad rap, we hear about how dogs get into them, but to actually see them in the wild, peaceful and as cute as they are, was really interesting.”

Albinism is quite rare in the animal kingdom and occurs due to a congenital absence of pigmentation.

Since appearing online, the footage has managed to rack up almost one million views.

Half a Century in the Making: Tree ‘Crop Circles’ Emerge in Japan

Two peculiar ‘crop circles’ have recently been spotted in Japan’s Miyazaki Prefecture. Viewable only from above, they were formed by sugi (Japanese cedar) trees.

Conspiracy theorists will be disappointed to learn that there is a very practical explanation for how these shapes emerged: science. Specifically, it was the result of a scientific experiment that spanned close to 50 years.

According to documentation (PDF) we obtained from Japan’s Ministry of Agriculture, Forestry and Fisheries, in 1973 an area of land near Nichinan City was designated as “experimental forestry” and one of the experiments was to try and measure the effect of tree spacing on growth. The experiment was carried out by planting trees in 10 degree radial increments forming10 concentric circles of varying diameters.

Part of what makes the crop circles so alluring are their concave shape, which was an unexpected result of the experiment that would suggest tree density does indeed affect growth. The trees are due to be harvested in about 5 years but officials are now considering preserving the crop circles.

Below is an image from Google Earth, which is unfortunately a bit dark.
