Mark Handley (UCL, University College London) has simulation showing the orbits of various SpaceX Starlink satellite constellations. There are simulations of 72, 264 and 11927 satellites. SpaceX is launching 60 satellites at a time. SpaceX has 60 production Starlink satellites in orbit now for testing.
Scientists from Lawrence Livermore National Laboratory (LLNL) used giant lasers to flash-freeze water into its exotic superionic phase and record X-ray diffraction patterns to identify its atomic structure for the very first time — all in just a few billionths of a second. Superionic ice is a mix of a solid lattice of oxygen and …
Argonne researchers use genetic algorithms to find better superconductors. Certain patterns of defects composed of metallic inclusions were found to maximize the critical current. researchers developed a computer algorithm that treated each defect like a biological gene. Different combinations of defects yielded superconductors able to carry different amounts of current. Once the algorithm identified a …
Superconductivity was achieved at a record high temperature of minus-23 degrees Celsius (minus-9 degrees Fahrenheit)—a jump of about 50 degrees compared to the previous confirmed record. This was done at high pressures that were 1.5 million times more than sea level atmosphere. Researchers at the Max Planck Institute for Chemistry in Germany teamed up with …
Kevin Kelly compare how much self-driving car data that Tesla has compared to Ford. Tesla has over 10 billion miles of self-driving car data but Ford has Zero miles of self-driving car data.
Researchers used high-frequency atmospheric observations from Gosan, South Korea, and Hateruma, Japan, and global monitoring data and atmospheric chemical transport model simulations to determine that manufacturers in northeastern China increased production of ozone-destroying CFCs by about 7000 tons per year from 2014 to 2017. Emissions from eastern mainland China are 7000 tons per year higher …
Tesla’s Shanghai Gigafactory 3 will produce electric cars for India and other Asian countries along with China. Tesla maybe able to saturate China and enter other markets such as India with electric vehicles that are immediately competitive in price. Reports indicate Tesla will target 3000 cars per week initially at GF3 and then scale to …
The leader of Italy’s right-wing League Party, Matteo Salvini, said populist and nationalist parties will control at least 150 seats in the new 751-seat European Parliament. ECFR (European Council on Foreign Relations) published results of surveys that show most Europeans believe the EU could fall apart within the next two decades. Salvini told RAI state …
The US Army has approved plans for high-powered microwave weapons, laser weapons and the development of hypersonic missiles. The Army will test a 50-kilowatt laser on an 8×8 Stryker armored vehicle by 2021 and then a 100-kW one on a heavy HEMTT truck. 100-KW lasers on an army truck Starting in 2021, the Army will …
The $80 million Special Ops TALOS exoskeleton failed to develop real-life Iron Man exoskeleton armor. The energy systems and other technology are not ready. However, a dozen components will be developed. Special Ops will spend $16 million to develop components like body armor, exoskeleton, internal battery pack, and vital systems monitoring technologies. These will make …
Elon Musk has tweeted that SpaceX will start construction of the booster stage of the Super Heavy Starship in three months. The first prototype will have 20 Raptor engines instead of 31 to lower the amount of hardware at risk. The rendering above was by Kimi Talivitie. Kimi is the original creator of a rendering …
