The US Navy has still not fixed the major problems with the USS Ford aircraft carrier. In 2019, four of the eleven weapons elevators were broken. There were supposed to be eleven weapons elevators. In May, 2021, the US Navy confirmed four lower-stage advanced weapons elevators will not be certified until later in 2021. This …
SpaceX will launch four orbital tourists before Virgin Galactic or Blue Origin launch their first sub-orbital tourists. Inspiration4 is a planned SpaceX Crew Dragon mission to low Earth orbit operated by SpaceX on behalf of Jared Isaacman. The flight is scheduled to launch on 15 September 2021. The mission is expected to launch in September …
SpaceX has filed its first Super Heavy Starship orbital flight plan. The Super Heavy Booster will return and land in Texas. The Starship will go to orbit and then land in Hawaii (Kauai) about 90 minutes after taking off. The Starship Orbital test flight will originate from Starbase, TX. The Booster stage will separate approximately …
Tesla Expansion of the Shanghai factory is progressing. Tesla construction workers told the Global Times that expansion of Tesla’s factory is progressing and is expected to be completed in the near future. Workers were seen busily working on a construction site on a plot of land across the road from the plant. This is contrary …
Elon Musk is working with Doge devs to improve system transaction efficiency. He says it is potentially promising. Dogecoin uses around 0.1 kWh per transaction compared to the over 1000 kWh per Bitcoin transaction. XRP and Dogecoin are among the most energy-efficient cryptocurrencies. Working with Doge devs to improve system transaction efficiency. Potentially promising. — …
Reservoir computing is an approach to make machine learning algorithms run faster. The word reservoir refers to a dynamical system. The reservoir consists of a bunch of recurrently connected units that are connected randomly. The main forms of reservoir computing use a recurrent neural network, and instead of updating all parameters of the network, it …
Researchers at the University of Nottingham have developed an ultrasonic imaging system, which can be deployed on the tip of a hair-thin optical fibre, and will be insertable into the human body to visualise cell abnormalities in 3D. The new technology produces microscopic and nanoscopic resolution images that will one day help clinicians to examine …
Magnetic helicity dynamics are important in solar flares and coronal mass ejections. Magnetic helicity is present in the solar wind. Its conservation is very important in dynamo processes. It also plays a role in fusion research, for example in reversed field pinch experiments. There is now work to create plasma guns and systems that leverage …
There is a new gene-editing tool called Retron Library Recombineering (RLR) that makes this task easier that has been developed by George Church and his team. RLR generates up to millions of mutations simultaneously, and “barcodes” mutant cells so that the entire pool can be screened at once, enabling massive amounts of data to be …
Philip Lubin and his team are continuing to make progress toward laser pushed sails. This is a way to achieve significant fractions of the speed of light for interstellar missions and a way to beam power for movement within the solar system at high speeds. One of the key aspects to this work is phase …
The Limitless Space Institute had a report from its Interstellar Initiative Grant recipients. One of the presenters is from the University of Albama who are working on a sub-kilowatt system to generate nuclear fusion pulses for propulsion. Dr. Jason Cassibry, an associate professor of mechanical and aerospace engineering and an assistant research professor at the …
