The US Navy will place its first at-sea hypersonic missiles aboard one of the service’s three Zumwalt-class destroyers in four years (by 2025). These will likely be hypersonic warheads on regular vertically launched missiles. Hypersonic warheads can go faster and can move around more than regular warheads. Hypersonic weapons go at 5 times the speed …
TSMC evolutionary N4 process will enter risk production later in 2021 and will be used for mass production in 2022. 80% of TSMC’s $30 billion capital budget this year will be spent on expanding capacities for advanced technologies, such as 3nm, 4nm/5nm, and 6nm/7nm. N5 capacity will increase to 110,000 to 120,000 wafers per month. …
Taiwan Semiconductor will be mass-producing Apple’s new M2 chip in July for use in MacBooks for the second half of 2021. The M2 will eventually be used in other Mac and Apple devices beyond the MacBook. The new chipset is produced by key Apple supplier Taiwan Semiconductor Manufacturing Co., the world’s largest contract chipmaker, using …
SpaceX presented a version of a fully reusable two-stage Super Heavy rocket in 2016. It was the Interplanetary Transport System. China has now presented a video of a fully reusable two-stage super-heavy rocket. China’s video is more cartoonlike. China will have to upgrade its rendering for a more photorealistic video. You can compare the videos. …
The $2.9 billion NASA funding for the SpaceX Lunar Starship means that a Starship will get man-rated for four astronauts. This means getting the chance of loss of crew less than one in 500 for a lunar landing. SpaceX Lunar Starship will only initially support four astronauts because the launch will be performed by SLS …
SpaceX has launched another 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The Falcon 9 first stage rocket booster supporting this mission previously supported launch of GPS III Space Vehicle 03, Turksat 5A, and four Starlink missions. This was also the 81st successful recovery of a …
The 2020 US Department of Defense reports that China’s Navy has more vessels than the US Navy. The PRC has the largest navy in the world, with an overall battle force of approximately 350 ships and submarines including over 130 major surface combatants. In comparison, the U.S. Navy’s battle force is approximately 293 ships as …
Here is The 2021 battery technology roadmap from the Journal of Applied Physics. A roadmap presents an overview of the current state of various kinds of batteries, such as the Li/Na/Zn/Al/K-ion battery, Li–S battery, Li–O2 battery, and flow battery. Above- Ragone plot illustrating the performances of specific power vs specific energy for different electrical energy-storage …
In 2020, LG Energy Solution added the most passenger EV battery capacity deployed onto roads. It is supplying Tesla in China and VW, Renault and Mercedes in Europe. CATL added the second most battery production capacity in 2020. CATL wants to increase its production capacity between 2020 and 2025 in the following stages: 110 GWh …
The social distancing, specifically the Six-Foot Rule, a guideline that offers little protection from pathogen-bearing aerosol droplets sufficiently small to be continuously mixed through an indoor space. The importance of airborne transmission of COVID-19 is now widely recognized. While tools for risk assessment have recently been developed, no safety guideline has been proposed to protect …
The Interstellar Probe is a space mission to discover physical interactions shaping globally the boundary of our Sun`s heliosphere and its dynamics and for the first time directly sample the properties of the local interstellar medium (LISM). Interstellar Probe will go through the boundary of the heliosphere to the LISM enabling for the first time …
