Qualcomm’s Snapdragon X Elite will eventually face competition in the ARM-based AI chipset space from MediaTek and NVIDIA, who have reportedly joined forces to co-develop a new SoC whose design is said to be finalized in the third quarter of this year. The upcoming silicon is said to support advanced technologies, including being mass produced on TSMC’s 3nm process, with the new entrant possibly competing with Apple’s M4 when comparing lithography.

The unnamed chipset from MediaTek and NVIDIA is rumored to fetch a price of $300 per unit, likely due to leveraging advanced nodes and packaging technologies

With the AI PC segment estimated to grow massively by 2027, MediaTek and NVIDIA want to pounce on this opportunity, giving this category a healthy dose of competition. The Taiwanese fabless semiconductor manufacturer has already received praise from Morgan Stanley analysts for its Dimensity 9,300, so there is no question that the company’s chip-making prowess has a gold-standard label. Add NVIDIA to the mix, and we could see an SoC that overtakes the competition in graphics performance, though Economic News Daily has not mentioned this.

How will liquids boil under reduced gravity, specifically on the Moon and Mars? This is what a recent project hopes to address as a team of researchers led by the Southwest Research Institute (SwRI) and working with Texas A&M University investigated the behavior of boiling liquids under reduced gravity using parabolic flights that are designed to simulate reduced gravity conditions. This project holds the potential to help researchers and future astronauts better understand how to manage boiling liquids during long-term space missions to the Moon and Mars where the gravity is one-sixth and one-third of the Earth’s, respectively.

“We have so little data about how boiling works in reduced gravity,” said Kevin Supak, who is a program manager at SwRI and the project lead. “Our experiment studies boiling in conditions that simulate lunar and Martian gravity levels using four different surfaces to examine how bubbles initiate and detach.”

NASA’s Office of Technology, Policy, and Strategy (OTPS) is asking members of the lunar community to respond to a new Lunar Non-Interference Questionnaire that will inform the development of a framework for further work on non-interference of lunar activities. There is no funding or solicitation expected to follow.

OTPS was created in November 2021 within the Office of the NASA Administrator to work transparently in collaboration across NASA and with the broader space community to provide NASA leadership with a trade space of data-and evidence-driven options to develop and shape NASA policy, strategy, and technology.

As dozens of countries and private sector companies have expressed interest in establishing lunar operations by the end of the decade, including many in the South Pole region, it will be critical to determine how to minimize interference and contamination in lunar activities. Deconfliction has been identified as an area of further work in Section 11 of the Artemis Accords and will be an area of increasing importance as the number of commercial and international actors operating on the lunar surface grows.

SpaceX’s Starship is coming to the Kennedy Space Center in Florida – and its plan to use the launch facility means the Federal Aviation Administration will probe the potential environmental impact of Elon Musk’s most powerful rockets blasting off the US East Coast.

NASA’s Environmental Assessment (EA) for the whole affair was completed in September 2019. The potential environmental impact of constructing and operating the site for Starship Super Heavy vehicles was considered, and a Finding Of No Significant Impact (FONSI) was made.

However, that was for approximately 24 Starship Super Heavy launches per year. According to the FAA, SpaceX’s latest proposal would involve constructing the necessary infrastructure to support up to 44 launches per year.
