ROCKET TEST: Engineers at NASA’s Glenn Research Center have tested a rocket engine injector made with additive manufacturing (AM), the 3D printing process that allows complex shapes to be crafted at a fraction of the time and cost of traditional machining. Aerojet Rocketdyne produced the injector assembly, which fired liquid oxygen and gaseous hydrogen in the test series, using high-energy lasers to melt metallic powder in a buildup process.
HOUSTON — Ad Astra Rocket Co., developer of the Variable Specific Impulse Magnetoplasma Rocket (Vasimr), is moving forward with modifications to the company’s 200-kw. VX-200 ground test article intended to allow characterization of the engine’s thermal steady state.
NEW MOON: An astronomer using the Hubble Space Telescope has discovered a tiny moon orbiting Neptune, bringing to 14 the number of known satellites orbiting the blue-green gas giant. Designated S/2004 N 1, the moon measures an estimated 12 mi. across and completes an orbit every 23 hr. at an altitude of about 65,400 mi. above the planet’s clouds. Mark Showalter of the SETI Institute found the new moon between the orbits of Larissa and Proteus while trying to track fast-moving ring segments around Neptune.
NEW CREW: U.S., Japanese and Russian astronauts Kjell Lindgren, Kimiya Yui and Oleg Kononenko will launch to the International Space Station in June 2015, where they will join American commander Scott Kelly and cosmonaut Mikhail Kornienko, who are scheduled to be three months into the station’s first year-long stay. Lindgren, a former NASA flight surgeon, and Yui, a retired Japanese military officer, are rookies. Kononenko logged 393 days on two previous ISS missions. They’ll spend about six months in orbit, the ISS partnership announced July 10.
PARIS — Sweden launched an enormous, helium-filled balloon from its Esrange Space Center on July 12, carrying the PoGOLite (Polarised Gamma-ray Observer) telescope dangling beneath it.

PARIS — Thales Alenia Space of France and Italy expects to complete a new turnkey satellite integration and test center for the Turkish military this fall, with final acceptance of the new facility, including all test systems, slated for May 2014.
Walking through the Paris air show last month, I was struck by the large number of companies exhibiting under one regional or cluster umbrella. There were, to mention a few, Aerospace Valley, Rockford Area Aerospace Network, Monterrey Aerocluster Mexico, Isle of Man Aerospace Cluster, Aero Montreal, Skywin Wallonie and Northwest Aerospace Alliance. Such groupings have a basic economic rationale: They allow small suppliers to be present at a show without bearing the full costs of renting their own stands in an exhibit hall.
In the 1960s, NASA had a couple of ways to get to the surface of the Moon. They came together in this famous November 1969 photo of Apollo 12 Commander Pete Conrad examining the Surveyor 3 robotic lander, with the lunar module Intrepid that brought him to the Moon parked on the horizon. Those days are long gone now, but the U.S. space agency still wants to go to the Moon—for science and for exploration experiments.

PARIS — Turkey advanced plans for developing a new launch vehicle July 11, signing an agreement with national missile-maker Roketsan for the pre-conceptual design phase of the new launcher, according to Turkey’s defense ministry.
In a sign that NASA’s Texas footprint is still changing two years after the shuttle program’s retirement, Johnson Space Center Deputy Director Steve Altemus will retire this month to lead Houston-based startup Intuitive Machines, which will offer NASA-honed engineering expertise to the global energy and health care sectors as well as commercial aerospace.
NASA and the Center for the Advancement of Science in Space (Casis) must strive harder to make full use of the International Space Station (ISS) if taxpayers are to recoup returns on its substantial assembly and annual operating costs, according to NASA Inspector General Paul Martin.
PARIS — The European Space Agency (ESA) has settled on the basic design of the Ariane 6, the next-generation launch vehicle that will succeed Europe’s heavy-lift Ariane 5. Known as the “Multi P Linear” concept, the launch vehicle will comprise four solid-fueled boosters that make up the rocket’s first and second stages, topped by a cryogenic third stage based on the Vinci engine, which is being developed by the Snecma motors division of France’s Safran as part of a midlife upgrade to the current Ariane 5, known as Ariane 5ME.
HOUSTON — Astronauts Chris Cassidy and Luca Parmitano extended power cabling across the outside of the International Space Station’s U.S. segment for a future Russian lab, pre-staged utility lines and hardware to deal with potential cooling and power system failures and retrieved external science experiments during a NASA-sponsored July 9 spacewalk.
PARIS — Arianespace will loft the Eutelsat 25B and Indian G-Sat 7 satellites together on an Ariane 5 by the end of August, following the launch of Europe’s Alphasat I-XL and India’s Insat 3D atop the heavy-lift rocket July 25. The missions will mark the third and fourth of a planned five Ariane 5 launches in 2013, says Arianespace CEO Stephane Israel, who took the helm of the European launch consortium in April.
NEW DELHI — The Indian space agency’s Mars Orbiter Mission is on target to lift off in the third week of October. “The Mars mission is getting ready at our Satellite Centre in Bengaluru [in southern India],” says Indian Space Research Organization (ISRO) Chairman K. Radhakrishnan. “We are planning to start stacking [the launch vehicle] from July 29, and the launch will be any day from Oct. 21 from the spaceport at Sriharikota.” Following the launch, the mission is expected to take eight months to reach Mars.
