Wang Yunfei, a naval expert, told the South China Morning Post that China will have four nuclear-powered aircraft carriers with electromagnetic launchers by 2035. Those carriers are expected to be comparable in size and launch capability to US aircraft carriers. China would have two smaller diesel powered aircraft carriers. In 2018, China started building another …
Elon Musk described various aspects of the SpaceX Super Heavy booster. The Superheavy booster will land tail first. The stainless body will not need any extra heat shielding. Rocket booster temperatures won’t go much above 600 Kelvin on hottest parts of main body & maybe around 1200K on base, which uncooled steel can handle. Starship …
Newly released NASA images contain important scientific information about the shape of Ultima Thule double asteroid. Above – Scientists’ understanding of Ultima Thule has changed as they review additional data. The “old view” in this illustration is based on images taken within a day of New Horizons’ closest approach to the Kuiper Belt object on …
Next year the world will have its first ExaFlop Supercomputer. This supercomputer will likely be built in China. The USA will follow about 12 months after with the A21 ExaFlop supercomputer in 2021. Ten researchers from China’s National University of Defense Technology (NUDT) recently published a paper that describes pushing current technologies to 1000 times …
IBM will invest $2 billion to develop artificial intelligence hardware and boost AI performance by 1000 times over the next ten years. IBM is partnering with State University of New York to develop an AI Hardware Center at SUNY Polytechnic Institute in Albany. New York will also provide a subsidy of $300 million. The IBM …

There is a 24-page 2019 Missile Defense Review Summary. There will be a comprehensive approach to prevent and defeat adversary missile attacks through a combination of deterrence; active …
The first Exaflop supercomputers are just scaling up with energy efficient modifications the technologies that have enabled the 100-200 petaFlop supercomputers. Super Cool Technologies Beyond the Exaflop Supercomputer DownUnder GeoSolutions (DUG) has started making petaflop supercomputers that are much more energy efficient by switching to dielectric liquids for cooling. They are cutting energy usage and …
Space startup Orbex has revealed the world’s largest 3D printed rocket engine. The Orbex prototype of the Stage 2 rocket is made from a specially-formulated lightweight carbon fiber and aluminium composite. It includes the world’s largest 3-D printed rocket engine. Orbex Prime launchers are up to 30% lighter and 20% more efficient than any other …
People freak out when they discover that computers and MRI can already read our minds. Columbia University researchers just announced the ability of computers and MRI to read brain signals and convert them into clear spoken words.
The SpaceX Super Heavy booster and Starship need the raptor engine to have at least 170 tons of thrust and tests have now proved more that level of thrust. This power level was achieved with warm fuel. An actual launch will freeze the fuel to cryogenic temperatures which will increase the thrust by 10 to …
NASA is targeting March 2 for launch of SpaceX’s Crew Dragon on its uncrewed Demo-1 test flight. Boeing’s uncrewed Orbital Flight Test is targeted for launch no earlier than April. Extra time was needed to complete hardware testing, data verification, remaining NASA and provider reviews, and training of flight controllers and mission managers. In January, …
