NASA and the U.S. Dept. of Energy have come together to solicit design proposals for a nuclear reactor that will power Lunar and Martian exploration!


Over the next fifteen years, multiple space agencies and their commercial partners intend to mount crewed missions to the Moon and Mars. In addition to placing “footprints and flags” on these celestial bodies, there are plans to establish the infrastructure to allow for a long-term human presence. To meet these mission requirements and ensure astronaut safety, several technologies are currently being researched and developed.

At their core, these technologies are all about achieving self-sufficiency in terms of resources, materials, and energy. To ensure that these missions have all the energy they need to conduct operations, NASA is developing a Fission Surface Power (FSP) system that will provide a safe, efficient, and reliable electricity supply. In conjunction with solar cells, batteries, and fuel cells, this technology will allow for long-term missions to the Moon and Mars in the near future.

For NASA, having fission reactors for lunar surface operations is a vital part of the Artemis Program, which aims to create a program of “sustained lunar exploration.” This means infrastructure is required, like the Lunar Gateway (where spacecraft will dock and resupply) and the Artemis Base Camp on the surface, where astronauts will eat, exercise, and sleep when not conducting extravehicular activities (EVAs) – i.e., surface operations.

On Christmas Eve, three days after its launch, Apollo 8 reached its destination, successfully carrying humans closer to the Moon than ever before. Finally, the US had beaten the Soviets to a major lunar milestone.

It would have been possible for the crew to simply loop around the Moon and come straight back to Earth. But since the mission was running smoothly (bar a case of space sickness on the part of Commander Frank Borman), the order was given to enter lunar orbit.

The crew now had to fire the service module’s engine for exactly the right amount of time.

Scientists in California tried to study Alzheimer’s disease from a different perspective and the results may have led them to the cause of the disease.

Researchers at the University of California-Riverside (UCR) recently published results from a study that looked at a protein called tau. By studying the different forms tau proteins take, researchers discovered the difference between people who developed dementia and those who didn’t.

The tau protein was critical for researchers because they wanted to understand what the protein could reveal about the mechanism behind plaques and tangles, two critical indicators doctors look for when diagnosing people with Alzheimer’s.

Elon Musk thinks SpaceX needs to ramp up production of its next-generation Raptor engine soon or face potentially dire consequences, according to media reports.

Raptors will power Starship, the huge, fully reusable vehicle that SpaceX is developing to take people and cargo to the moon, Mars and other distant destinations. Each Starship will need a lot of Raptors — 33 for the giant first-stage booster, called Super Heavy, and six for the upper-stage spacecraft, known as Starship.

An asteroid the size of the Eiffel Tower is heading towards Earth this month and it’s considered an especially unique piece of rock by scientists.

The asteroid 4,660 Nereus is classified as a “potentially hazardous” piece of rock because of its proximity to Earth. On Dec. 11, NASA expects it to be at its closest point to Earth over a 20-year period. The asteroid was discovered back in 1982.

The race to find medical treatments for Covid-19—and future pandemics—is on, driving renewed investments by the healthcare and pharmaceutical industries in Real-World Data (RWD) and Real-World Evidence (RWE). A new report on AI and the real-world studies industry, from Deep Pharma Intelligence (DPI), Evomics Medical and The Yuan (an online forum focused on AI in healthcare, for which I am a contributor), provides fresh insights into this rapidly evolving patient-centric approach to increasing R&D efficiency, accelerating the introduction of new drugs, and improving health outcomes.

Qualcomm kicked off its annual Snapdragon Technology Summit with its new premium smartphone SoC dubbed the Snapdragon Series 8 Gen 1. As expected, the new SoC improves performance and efficiency in every aspect of the chip, but enhancements in AI and image processing are especially important for the next generation of premium smartphones.

The new Series 8 Gen 1 SoC follows the previous Snapdragon 888 generation as Qualcomm’s premium smartphone SoC. And yes, there is a new naming convention with this generation. Rather than continuing to count up until the company runs out of numbers for new products, Qualcomm changed the naming convention to that basic series number (Series, 8, 7, 6, and 4) followed by a generational number, similar to what the company began doing with its Snapdragon 8CX SoCs for PCs. Since this is the first generation of smartphone SoCs to use the new nomenclature, the new family of devices will be “Gen 1”. For now, however, the company only announced the premium chip — the Series 8 Gen 1.

Mexican biologist Ingrid Fetter-Pruneda is studying the longevity and fertility in ants in the hope of helping to develop strategies to avoid, slow down or reverse female reproductive aging in other animals or in humans.

Fetter-Pruneda, an Assistant Professor at the Universidad Nacional Autónoma de México (UNAM), says most animals show a trade-off between longevity and fertility, but one of the most striking features of ants is that the queens are simultaneously very long lived and very fertile, while the workers are short lived and sterile.

“I am trying to figure out the cellular and molecular mechanisms that allow queens to remain fertile throughout their relatively long lives,” Fetter-Pruneda says, “Many molecular pathways are conserved across many species, and new discoveries in ants could help direct research in other organisms.”
