NEXT MISSION: As NASA’s Mars Science Laboratory rover prepares for its first moves, the agency is looking ahead to its next mission on the surface of the red planet. To launch in 2016, InSight will place instruments on the Martian surface to investigate whether the planet has a solid or liquid core, and why the planet’s crust is not divided into tectonic plates, like that of the Earth. The French and German space agencies are contributing instruments to InSight, which will land in September 2016 to begin a two-year mission.
U.S. and French scientists plan to test the Chemistry and Camera (ChemCam) instrument on NASA’s Curiosity rover by “zapping” a nearby rock with “several megawatts” of laser power in the next few days and analyzing the resulting spectra to determine the target’s composition.
HUNTSVILLE, Ala. — The U.S. Army is exploring whether a short-range missile defense target, designed to be one-third the price of using Patriot missiles in such a role, can feasibly be added to its arsenal to reduce the cost of flight testing. The Economical Target makes use of surplus rocket motors, coupled with a rudimentary rocket body to effectively form a sounding rocket suitable for some missile defense tests, says Thomas Webber, acting director for rapid transition at Army Strategic Command.
Two demonstration Space Tracking and Surveillance System (STSS) satellites, built by Northrop Grumman, captured these infrared images of a ballistic missile intercept from their low Earth orbit. In 2009, the U.S. Missile Defense Agency (MDA) lofted the two STSS satellites, developed under the then-Space-Based Infrared System-low program, to explore whether orbiting spacecraft could be used to track warheads in mid-flight.

Aviation Week's 2012 Workforce Study data come from respondents that collectively employ 80% of the A&D industry's workforce of 624,000. Newcomers to this year's study include Alenia Aermacchi North America and Acutec Precision Machining.
LOGAN, Utah — Additive Manufacturing (AM) technology used to make parts for high-performance race cars is being applied to the tricky problem of propulsion for cubesats and other small spacecraft that are typically launched as secondary payloads. Matthew Dushku, head of the Experiment Propulsion Lab here, has tested a hybrid rocket motor created with a 3-D printing technique from Windform XT 2.0, a picocarbon reinforced nylon material that can be laid up in layers as a powder and hardened with a laser scanner.
PASADENA, Calif. — Even as more senior staffers at the Jet Propulsion Laboratory here begin to explore Mars with the state-of-the-art Curiosity rover, a group of scientists, engineers and neophyte managers in their 20s is preparing to use whatever is at hand to validate space-to-ground laser communications.
LOGAN, Utah — A growing market in the developing world for small satellites and demand for more capable orbital spacecraft like Darpa’s planned Phoenix testbed are behind ATK’s recent decision to broaden its line of small satellites.
GREEN FUEL: NASA has picked Ball Aerospace & Technologies Corp. of Boulder, Colo., to lead an orbital demonstration of a “green” spacecraft propellant alternative to hydrazine. While an efficient and storable propellant, hydrazine is highly corrosive and toxic. The team will develop and fly a high-performance green propellant, demonstrating and proving the performance of the integrated propulsion system. The agency’s Green Propellant Infusion Mission is expected to fly in about three years.
RUSSIAN LOSSES: A botched Russian launch junked two multimillion-dollar satellites last week that were to provide Indonesia and Russia with telecommunication services, adding to a series of failures that have dogged its space industry. Reuters reported that Russia’s space agency acknowledged the Aug. 7 failure of the upper stage of the launcher atop its workhorse Proton rocket. The error after takeoff from the Russian-leased Baikonur launch pad in Kazakhstan replicates a mishap that scrapped the $265 million Express AM-4 satellite last summer.
LOS ANGELES — NASA is on track to move the Mars Science Laboratory (MSL) Curiosity rover for the first time on the red planet’s surface around the middle of next week, according to controllers at NASA’s Jet Propulsion Lab in California. Preparations for the move come midway through Sol 9 on Mars (Aug. 14), as the MSL team nears the halfway point in the lengthy process of checking out and commissioning the rover’s 10 major science instruments and other avionics and mechanical systems.
