2+ day, 9+ hour ago   (591+ words) Researchers at Dalian University of Technology in China have tested a spacecraft protection structure made from water-filled aluminium eggshells, with the design reducing the velocity of an impact projectile by nearly 65 per cent. The research, published in the Journal of…...

3+ day, 14+ hour ago   (985+ words) Scientists have demonstrated a new method to produce methane fuel from Martian carbon dioxide using an advanced copper catalyst. Researchers at the University of Mississippi have developed a method that could help future Mars missions produce rocket fuel directly from…...

4+ day, 30+ min ago   (594+ words) Project West Ford tested a sparse ring of copper dipoles as a passive radio relay. Only part of its 480-million-needle payload dispersed individually, leaving a complicated legacy....

4+ day, 13+ hour ago   (400+ words) Space debris is one of the most pressing challenges in modern spaceflight; nearly a million fragments larger than a centimeter whirl around Earth at orbital speeds, each capable of puncturing or crippling a spacecraft. Against this backdrop, researchers at Dalian…...

4+ day, 14+ hour ago   (178+ words) 3D-printed aluminum eggshell arrays filled with water proved more effective at impact resistance. Another popular demonstration is the classic egg-drop challenge, in which students must figure out how best to protect a single egg from breaking when dropped from a…...

3+ week, 1+ day ago   (562+ words) Human urine could have an unlikely second life as a raw material for making hydrazine, an energy-rich chemical used in rocket propulsion and being explored for emerging energy systems. Researchers at the University of Adelaide have developed an electrochemical process…...
