Antarctica is estimated to contain as much as a quarter of Earth’s marine methane, and scientists have now revealed the first leak of the gas from the seabed, prompting major concerns about the impact on the global climate crisis.Methane is a particularly powerful greenhouse gas due to its ability to absorb heat. Over a 20-year period, a kilogram of methane warms the planet as much as 80 times...
Spaceflight and Tethers Unlimited team up on deorbiting system for satellite carrier
Seattle-based Spaceflight Inc. says it'll use a notebook-sized deorbiting system developed by another Seattle-area company to deal with the disposal of its Sherpa-FX orbital transfer vehicle. The NanoSat Terminator Tape Deorbit System, built by Bothell, Wash.-based Tethers Unlimited, is designed to take advantage of orbital drag on a 230-foot-long strip of conductive tape to hasten the fiery...
