HOUSTON — Robonaut 2, a NASA and General Motors collaboration to develop an astronaut-friendly humanoid, is due a pair of legs and a battery backpack later this year to give it more mobility inside and eventually outside the International Space Station. The two-armed, camera and force-sensor-laced torso launched to the station aboard a February 2011 space shuttle mission. It has been restrained to a stanchion in the station’s U.S. Destiny laboratory since it was awakened electronically for the first time late the following August.
SPACE LEGISLATION: Congress on Jan. 2 extended for one year an indemnification program allowing the government to share the cost with industry against injuries or property damage suffered by the public in a commercial space launch. The House sought a two-year extension, but the Senate shortened the timeline. The bill also provides a waiver through 2020 allowing U.S. astronauts to fly aboard Russian spacecraft to gain access to the International Space Station.
HOUSTON — Astronauts assigned to multi-month or multi-year missions to near-Earth asteroids and Mars may face an accelerated onset of Alzheimer’s-like symptoms from cosmic radiation exposure, according to a NASA-funded study by researchers at the University of Rochester Medical Center (URMC) that used mice as subjects.
Hurricane Sandy came and went in late 2012, as did many of the startup issues at Virginia’s Mid-Atlantic Regional Spaceport (MARS), elevating the prospects that Orbital Sciences Corp. will complete its NASA Commercial Orbital Transportation Systems program milestones in the new year and begin lucrative cargo deliveries to the International Space Station.
Advances in rocket engine technology do not come along often, so it was noteworthy in October 2012 when Orbital Technologies flew a sounding rocket powered by its “vortex” engine, which injects fuel and liquid oxygen so the burning mixture does not touch the walls of the combustion chamber, allowing it to be thinner, lighter and cheaper. Oxidizer is injected at an angle that sets up a pair of coaxial vortices. Combustion occurs in the innermost swirl, the outer vortex protecting the chamber walls from the heat of combustion.
The Pentagon continues to set the standard for research and development spending on missile defense, though purchases from allies are increasingly setting the production pace for regional defense systems. This trend is likely to continue in 2013, as Iran threatens Israel and other U.S. allies in the region.
European government bickering scuttled a mega-merger of EADS and BAE Systems, and the Pentagon continues to hold firm against further consolidation among its top contractors. But consolidation amid second- and third-tier contractors is likely to accelerate as defense spending heads down in the U.S. and Europe.
Could optionally piloted vehicles (OPV) be the next wave in cost-effective special-mission aircraft, able to fly in civil airspace with pilot and sensor operator on board but also capable of flying unmanned for far longer duration at lower cost than the Beechcraft King Airs so favored today? Aurora Flight Sciences and Northrop Grumman would answer yes. Aurora is developing the $4.5 million Centaur OPV, and its first buyer is Switzerland's Arma-suisse, which will use it as a flying testbed for unmanned-aircraft airspace integration.
Unmanned vessels are about to take a leap in capability, on the surface and beneath. The desire for persistent sensing is driving the need to develop fully autonomous, long-duration vehicles that can covertly patrol coastal waters or overtly follow submerged submarines. The U.S. Office of Naval Research plans to build prototypes of the Large-Displacement Unmanned Underwater Vehicle (LDUUV) to address the autonomy, sensing and energy challenges of a vessel able to operate independently for months.
NASA Space Launch System (SLS) advocate Sen. Kay Bailey Hutchison (R-Texas) is leaving Capitol Hill, but the program should get a boost by meeting an early test. An engineering board has cleared the first element of the heavy-lift rocket for preliminary manufacturing, keeping the program on track for a first flight with the Orion multipurpose crew vehicle in 2017.
Displays are getting personal. As soldiers join the network they need displays, and today's ruggedized laptops are heavy, power-hungry and breakable. The push is on to field lightweight, flexible displays that can be worn on the wrist or integrated into clothing or protective eyewear. The U.S. Army is testing wrist displays, and the U.S. Air Force kneepad touchscreens, produced by L-3 Display Systems using unbreakable plastic-backed organic light-emitting diode (OLED) technology from Universal Displays. These displays are small—only 4.3-in.
While privacy concerns bedevil efforts to integrate unmanned aircraft into U.S. national airspace, police departments across the country are pushing ahead with plans to field small unmanned aircraft systems (SUAS) operating under existing rules. The vehicle of choice appears to be a miniature rotorcraft, providing the ease of operation that comes with vertical-takeoff-and-landing and the ability to hover and stare. Canada's Draganfly Innovations has led development of the public-safety market with its 4.5-lb.
North Korea's successful launch of a satellite in December after 14 years of attempts put the hermit kingdom one step closer toward deploying an intercontinental ballistic missile. And Iran's nuclear weapons program—and the threat of an Israeli attack to cripple it—will keep tensions simmering in the Middle East.
NASA wants $800 million in fiscal 2013 for its program to outsource the transport of crews to and from space, and says if it does not get the funding first commercial flights to the International Space Station will slip to 2018. With station funding set to expire in 2020, that could be a problem.
When I began writing this column eight years ago, airlines were reeling as oil prices soared above $50 a barrel. Lockheed Martin was hoping to ramp up production of the Joint Strike Fighter in 2009, and Wall Street analysts were beginning to question whether a run-up in defense stocks had much steam left. Airbus was preparing to launch development of the A350 in response to Boeing's 7E7 (now 787), and the business jet market was embarking on a sales surge that would end in a spectacular crash.
As the U.S. military pulls out of Afghanistan and “resets” for the Pacific theater, will there be an accompanying shift in the Defense Department's intelligence, surveillance and reconnaissance forces? The year should see the beginning of a shift away from lower-tech systems geared to detect improvised explosive devices and toward future high-tech sensors.
After its unveiling of the J-20 and J-31 stealth fighters, it is not unimaginable that Beijing could pull off another technological surprise in 2013. Could it up the superpower stakes by testing an unmanned combat air vehicle, an air-launched strike weapon or even a mini-spaceplane? Speculation abounds.
The bifurcation of the business jet market is expected to continue in 2013, with strong demand for larger and pricier jets and sluggish sales of small and mid-sized aircraft. A Chinese company's failed bid in 2012 to acquire bankrupt Hawker Beechcraft is unlikely to slow Beijing's bid to become a significant player in the market.
Dozens of women are filling senior management positions across aerospace and defense, changing the face of an industry not known for diversity. Another glass ceiling will shatter on Jan. 1, when Marillyn Hewson (right) becomes CEO of Lockheed Martin and Phebe Novakovic fills the top spot at General Dynamics.
