Lucy Spacecraft Healthy as NASA
Established in 1,958 the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. It’s vision is “To discover and expand knowledge for the benefit of humanity.”

Scientists Make Hardened Wooden Knife That’s 3x Sharper Than Stainless-Steel
Posted by Quinn Sena in categories: materials, sustainability
The sharpest knives available are made of either steel or ceramic, both of which are man-made materials that must be forged in furnaces under extreme temperatures. Now, researchers have developed a potentially more sustainable way to make sharp knives: using hardened wood. The method, presented October 20th, 2,021 in the journal Matter, makes wood 23 times harder, and a knife made from the material is nearly three times sharper than a stainless-steel dinner table knife.
“The knife cuts through a medium-well done steak easily, with similar performance to a dinner table knife,” says Teng Li, the senior author of the study and a materials scientist at the University of Maryland. Afterward, the hardened wood knife can be washed and reused, making it a promising alternative to steel, ceramic, and disposable plastic knives.
Li and his team also demonstrated that their material can be used to produce wooden nails as sharp as conventional steel nails. Unlike steel nails, the wooden nails the team developed are resistant to rusting. The researchers showed that these wooden nails could be used to hammer together three boards without any damage to the nail. In addition to knives and nails, Li hopes that, in the future, the material can also be used to make hardwood flooring that is more resistant to scratching and wear.

New Marine Corps Robot Will Provide ‘Eyes in the Water’ for Explosive Device Removal Technicians
Posted by Dan Kummer in categories: robotics/AI, transportation
The Marine Corps is expanding its mission set to include operating robots in shallow waters, a first for the service that comes as it prepares to operate on islands in the Indo-Pacific.
The Explosive Ordnance Disposal Remotely Operated Vehicle is a box-shaped robot that can navigate in shallow waters, where it will be able to identify and neutralize threats, according to a Marine Corps Systems Command news release issued Thursday.
The robot, also referred to as an ROV for remotely operated vehicle, has high-definition video capability and the ability to provide real-time feedback for explosive ordnance disposal divers, according to the release. It also uses sound navigation and ranging sensors.

The Navy Invented a Device to Prevent People From Talking
Posted by Omuterema Akhahenda in category: military
The U.S. Navy has invented a new device to prevent people from speaking, one that people with siblings will recognize instantly. The handheld acoustic hailing and disruption device records a person’s speech and spits it back out again, disrupting their concentration and discouraging them from speaking further. Although an interesting—and very familiar—concept it’s unlikely this tech will ever see use on the battlefield.
The handheld acoustic hailing and disruption (AHAD) was developed by engineers at Naval Surface Warfare, Crane Division, a Navy research and development facility in Indiana that develops handheld and crew-served weapons for the service. The patent, New Scientist reports, was issued in 2019.
