Aerospace firms tout solar electric propulsion to Congress

A handful of private firms submitted testimony to Congress touting the potential uses of solar electric propulsion at a hearing on in-space propulsion held last week by the U.S. House of Representatives’ subcommittee on space. SEP systems could replace chemical propulsion for use in deep space exploration, but experts say the technology needs more improvement to become a viable propulsion option. “We are on the cusp of a giant leap

Lockheed Martin partners with NASA on telescope instruments to study dark energy, furthest reaches of space

Lockheed Martin is building tools to help NASA with  the hunt for data and more direct evidence of dark energy, the force physicists believe to be behind the universe’s accelerating expansion. The aerospace giant is developing a system of instruments that, if selected for production, will comprise the core tools installed on the Wide Field Infrared Survey Telescope (WFIRST), which aims not only to reveal hundreds of millions more stars, but to help study
