Grumman’s LongShot drone can search & destroy
Posted by Raphael Ramos in categories: drones, military, robotics/AI
Instead of firing missiles, planes may carry and launch unmanned drones that will be able to shoot their own missiles to search and destroy targets.
Aerospace giant Northrop Grumman is wasting no time in this competition.
Just two days after DARPA named it as one of three competitors for the LongShot contract, the company released an image of its concept for an air-launched unmanned aircraft system (UAS), Aviation Week reported.

Cruelty-Free Wallets From Banana Tree Waste
Posted by Raphael Ramos in category: sustainability
So you like a leather wallet? Check out this sustainable alternative made from banana tree waste! After banana trees are harvested, they’re chopped down to make way for younger fruiting trees, and their waste can become SO MUCH STUFF! Cruelty-free and super cool, what’s not to love?
Neil Tyson is a man to listen to!!
Astrophysicist that I have learned much from.

How Solar Sails Are Remaking Space Exploration
Posted by Derick Lee in categories: business, robotics/AI, space
Using the pressure of the sun’s rays to propel spacecraft, solar sails will allow future unmanned missions to be longer and cheaper while reaching the outer solar system—and possibly beyond.

Lab team uses giant lasers to compress iron oxide, revealing the secret interior of rocky exoplanets
Posted by Saúl Morales Rodriguéz in categories: space, sustainability
Advances in astronomical observations have resulted in the discovery of an extraordinary number of extrasolar planets, some of which are believed to have a rocky composition similar to Earth. Learning more about their interior structure could provide important clues about their potential habitability.
Led by Lawrence Livermore National Laboratory (LLNL), a team of researchers aims to unlock some of these secrets by understanding the properties of iron oxide —one of the constituents of Earth’s mantle—at the extreme pressures and temperatures that are likely found in the interiors of these large rocky extrasolar planets. The results of their experiments were published today in Nature Geoscience.
“Because of the limited amount of data available, the majority of interior structure models for rocky exoplanets assume a scaled-up version of the Earth, consisting of an iron core, surrounded by a mantle dominated by silicates and oxides. However, this approach largely neglects the different properties the constituent materials may have at pressures exceeding those existing inside the Earth,” said Federica Coppari, LLNL physicist and lead author on the study. “With the ever-increasing number of confirmed exoplanets, including those believed to be rocky in nature, it is critical to gain a better understanding of how their planetary building blocks behave deep inside such bodies.”
