If you tried to start a car that’s been sitting in a garage for decades, you might not expect the engine to respond. But a set of thrusters aboard the Voyager 1 spacecraft successfully fired up Wednesday after 37 years without use. NASA announces: Voyager 1, NASA’s farthest and fastest spacecraft, is the only human-made object in interstellar space, the environment between the stars. The spacecraft, which has been flying for 40 years, relies on small devices called thrusters to orient itself so it can communicate with Earth. These thrusters fire in tiny pulses, or “puffs, ” lasting mere milliseconds, to subtly rotate the spacecraft so that its antenna points at our planet. Now, the Voyager team is able to use a set of four backup thrusters, dormant since 1980. “With these thrusters that are still functional after 37 years without use, we will be able to extend the life of the Voyager 1 spacecraft by two to three years, ” said Suzanne Dodd, project manager for Voyager at NASA’s Jet Propulsion Laboratory, Pasadena, California.

Voyager 1 Fires Up Thrusters After 37 Years
New submitter joshtops shares a report from Scientific American: As NASA makes plans to one day send humans to Mars, one of the key technical gaps the agency is working to fill is how to provide enough power on the Red Planet’s surface for fuel production, habitats and other equipment. One option: small nuclear fission reactors, which work by splitting uranium atoms to generate heat, which is then converted into electric power. NASA’s technology development branch has been funding a project called Kilopower for three years, with the aim of demonstrating the system at the Nevada National Security Site near Las Vegas. Testing is due to start in September and end in January 2018. The last time NASA tested a fission reactor was during the 1960s’ Systems for Nuclear Auxiliary Power, or SNAP, which developed two types of nuclear power systems. The first system — radioisotope thermoelectric generators, or RTGs — taps heat released from the natural decay of a radioactive element, such as plutonium. RTGs have powered dozens of space probes over the years, including the Curiosity rover currently exploring Mars. The second technology developed under SNAP was an atom-splitting fission reactor. SNAP-10A was the first — and so far, only — U.S. nuclear power plant to operate in space. Launched on April 3, 1965, SNAP-10A operated for 43 days, producing 500 watts of electrical power, before an unrelated equipment failure ended the demonstration. The spacecraft remains in Earth orbit. Read more of this story at Slashdot. 
New submitter omaha393 quotes a report from R&D Magazine: Toyota announced a new initiative on Wednesday aimed at advancing its work in vehicles powered by alternative energy sources. The automaker unveiled Project Portal, which is a novel hydrogen fuel cell system designed for heavy duty truck use at the Port of Los Angeles. A proof-of-concept truck powered by this fuel cell will be part of a feasibility study held at the Port this summer, with the goal of examining the potential of this technology in heavy-duty applications. The test vehicle will produce more than 670 horsepower and 1, 325 pound feet of torque from two of these novel fuel cell stacks along with a 12kWh battery. Overall, the combined weight capacity is 80, 000 pounds that will be carried over 200 miles. omaha393 adds: “While hydrogen fuel has been criticized due to high cost of production and safety concerns, recent advances in catalysis and solid storage systems have made the prospect of hydrogen fuel an attractive commercial prospect for the future.” Read more of this story at Slashdot. 
China will invest $361 billion in renewable power generation between 2016 and 2020, the National Energy Administration (NEA) said Thursday, as the world’s largest energy market pushes to shift away from coal power. From a report: The investment will create over 13 million jobs in the sector, the NEA said in a blueprint document that lays out its plan to develop the nation’s energy sector in a five-year period. The NEA repeated its goal to have 580 million tonnes of coal equivalent of renewable energy consumption by 2020, accounting for 15 percent of overall energy consumption.
