Aug. 27, 2020 —In a year defined by obstacles, a student rocket team persevered. Working together across five time zones, they successfully designed a hybrid rocket engine that uses paraffin and a novel nitrous ...
May 17, 2022 —Researchers assessed the potential impact of a rocket launch on atmospheric pollution by investigating the heat and mass transfer and rapid mixing of the combustion byproducts. The team modeled the ...
Aug. 18, 2020 —In smaller spacecraft such as CubeSat satellites, a salt-based monopropellant is showing promise. It can be used both in high-thrust chemical propulsion for fast time-sensitive maneuvers, and ...
Aug. 3, 2021 —Researchers found that power could be sent to a free-flying drone via a beam of microwave radiation. The team estimated the efficiency of this process and compared it with that for a fixed-position ...
Aug. 2, 2021 —A vital piece of gas engines, combustors -- the chambers in which the combustion powering the engine occurs -- have the problem of breaking down due to fatal high-frequency oscillations during the ...
Nov. 16, 2022 —Following a successful launch of NASA's Space Launch System (SLS), the most powerful rocket in the world, the agency's Orion spacecraft is on its way to the Moon as part of the Artemis ...
Aug. 12, 2020 —Researchers have sent perovskite and organic solar cells on a rocket into space. The solar cells withstood the extreme conditions in space, producing power from direct sunlight and reflective light ...
Apr. 25, 2023 —Researchers develop a model to describe the interaction between a rocket plume and the surface of a planetary body in near-vacuum conditions. The computational framework takes in information about ...
June 26, 2022 —A formidable space tourism industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new ...
June 10, 2021 —New research used a system for monitoring nuclear tests to track the infrasound from 1,001 rocket launches, identifying the distinctive sounds from seven different types of rockets. In some cases, ...
