UPSTARTS WELCOME: Sending a clear warning shot across the bows of established launch suppliers, Gen. William Shelton, commander of Air Force Space Command, says the service is increasingly interested in the potential of emergent space companies like Blue Origin and Space Exploration (SpaceX). Propulsion systems recently demonstrated by Blue Origin “might well be worth examining for our own unmanned purposes,” Shelton says.

WRITE IN: In addition to its lawsuit against the service, Hawker Beechcraft is hoping to build political pressure on lawmakers and the Defense Department to force the U.S. Air Force to revisit its decision to award the Light Air Support (LAS) contract to Sierra Nevada/Embraer. The company has launched a letter-writing campaign, asking customers and other supporters to contact their local congressmen and the Pentagon. As a result, close to 5,700 letters had been sent to Congress and the Pentagon by the afternoon of Jan. 6, according to the company.

BEIJING — Testing has proved the effectiveness of crucial landing technology for China’s third lunar exploration mission, due to be launched in 2013, says national space contractor CAST. The mission, to be called Chang’e 3, is aimed at making advances in a wide range of technologies, CAST says. It lists them as soft landing, surveying the surface by rover, “survival on the lunar surface,” communications for long-distance monitoring and control, and direct injection into a lunar transfer orbit.

WATCH THE SKIES: Satellite trackers predict Russia’s Phobos-Grunt Mars mission will reenter the Earth’s atmosphere on or about Jan. 15, with a more precise forecast possible as it winds down toward the atmosphere. Carrying a Chinese probe piggyback, the 13,200-kg (29,040-lb.) spacecraft was left stranded in low Earth orbit after its Nov. 8, 2011, launch on a Zenit 2-SB rocket. Most of the probe’s liftoff mass was hypergolic fuel that may be frozen, and it carried a sample-return capsule that may survive reentry and reach Earth’s surface.

BELL PICKED: Bell Helicopter has entered final negotiations for the sale of 15 429s to the Turkish National Police, the company reports. The 429 is a new entrant in the light twin-engine helicopter market, and the company sees Turkey’s selection “as a significant win in the European market.”

LUKEWARM WELCOME: Just in time to help carry out new defense priorities and changes that the White House and Pentagon announced last week, the four-star chief of the National Guard has taken his seat on the Joint Chiefs of Staff. The move marks the first significant change to the Joint Chiefs since the Goldwater-Nichols Act of 1986, and brings full and equal Joint Chiefs representation to a part-time element of the military that not only is not a free-standing armed service, but is also shared with state governors. The move caps a decade-long effort.
