2013 winner of the Robert J. Collier Trophy

In a completely unsurprising choice, the X-47B won the Robert J. Collier Trophy for 2013 for “developing and demonstrating the first unmanned, autonomous air system operating from an aircraft carrier.”

Stephen Pope of Flying notes that this year’s award confirms the ascendancy of unmanned programs at the cutting edge of aerospace technology.

Piper Archer gets a diesel engine

One of my favorite airplanes has received a factory STC for a diesel engine. With increasing difficulty in obtaining aviation gasoline outside the United States, this is an important development to maintain general aviation on a global basis.

Ocean discovered on Enceladus

Using data from the Cassini spacecraft, scientists have discovered an ocean on Saturn’s moon Enceladus. The existence of liquid water makes Enceladus a high-priority target in the search for extraterrestrial life.

Researchers theorized the presence of an interior reservoir of water in 2005 when Cassini discovered water vapor and ice spewing from vents near the moon’s south pole. The new data provide the first geophysical measurements of the internal structure of Enceladus, consistent with the existence of a hidden ocean inside the moon. Findings from the gravity measurements are in the Friday, April 4 edition of the journal Science.
