Earth and Space for Educators

This FREE features Inspiration4 astronaut Chris Sembroski and educator Erin Duncan-Sembroski, along with your hosts, planetary scientist Dr. Kirby Runyon and space educator Dr. Mark Wagner. The high-energy one-hour session is focused on providing an overview of the three-day Earth and Space Experience coming up on November 7–9, 2025. Register now to learn about the geology at specific locations in Southern New Mexico, and how these sites are analogs for the Moon, Mars, and elsewhere in the solar system. Time is also allocated for a Q&A opportunity with all four speakers… come ready with questions! Participation in this also includes access to free space education resources that you can take back to share with your students or others in your community.

Note: This is appropriate for educators, industry professionals, and space enthusiasts from all walks of life. Space education is for everyone!

Chris “Hanks” Sembroski is a commercial astronaut, U.S. Air Force veteran, and passionate advocate for space exploration and STEM education. Best known for his role as Mission Specialist on the historic Inspiration4 mission in 2021, Sembroski spent three days in space, completing 47 orbits as part of the first all-civilian crew. With degrees in aeronautics and a career dedicated to advancing aerospace innovation, he has contributed to groundbreaking projects like Blue Origin’s New Glenn program and teaches as an adjunct faculty member at Embry-Riddle Aeronautical University. Chris’s journey reflects a lifelong passion for human spaceflight, from launching model rockets in college, leading teams through simulated missions at U.S. Space Camp, to advocating for space policy in Washington, D.C. He continues to inspire the next generation through his work as a speaker, educator, and industry leader, embodying the spirit of generosity and exploration.

PAPO: Perception-Aware Policy Optimization for Multimodal Reasoning

Suppose you’re trying to solve a puzzle that includes both words and pictures — like reading a comic strip and figuring out what happens next. That’s the kind of challenge today’s AI faces in “multimodal reasoning,” where it must understand both text and images to think and respond accurately.

Rivian CEO Exposes Legacy Automaker EV Lies

Rivian CEO RJ Scaringe claims that legacy automakers are intentionally slowing down electric vehicle adoption and hindering competition to protect their profits from gas-powered vehicles, which could threaten their survival and allow newer EV makers like Rivian and Tesla to dominate the market ## ## Questions to inspire discussion.

Legacy Automakers and EVs.

🚗 Q: Why are legacy automakers resistant to selling EVs? A: Legacy automakers don’t want to sell EVs because they make good margins on low-efficiency gas cars and can sell them at a premium price, preferring to see the EV market disappear.

🏛️ Q: How are legacy automakers fighting against EV policies? A: Legacy automakers are the biggest adversaries of EV policies, spending the most energy fighting against them in DC, reflecting their desire for the EV market to vanish. Rivian’s Challenges and Strategy.

💰 Q: What financial challenge does Rivian face? A: Rivian has a massive $23 billion debt, making it more indebted than any startup has ever been, requiring 10–20 years to become cash flow positive.

🛻 Q: How is Rivian addressing its product pricing? A: Rivian’s R2 electric truck, launching in 2025, will target a **$45,000 starting price, a strategic move to make their products more accessible.

AI and biophysics unite to forecast high-risk viral variants before outbreaks

When the first reports of a new COVID-19 variant emerge, scientists worldwide scramble to answer a critical question: Will this new strain be more contagious or more severe than its predecessors? By the time answers arrive, it’s frequently too late to inform immediate public policy decisions or adjust vaccine strategies, costing public health officials valuable time, effort, and resources.

In a pair of recent publications in Proceedings of the National Academy of Sciences, a research team in the Department of Chemistry and Chemical Biology combined biophysics with artificial intelligence to identify high-risk viral variants in record time—offering a transformative approach for handling pandemics. Their goal: to get ahead of a virus by forecasting its evolutionary leaps before it threatens public health.

“As a society, we are often very unprepared for the emergence of new viruses and pandemics, so our lab has been working on ways to be more proactive,” said senior author Eugene Shakhnovich, Roy G. Gordon Professor of Chemistry. “We used fundamental principles of physics and chemistry to develop a multiscale model to predict the course of evolution of a particular variant and to predict which variants will become dominant in populations.”

Ocean model simulations shed light on long-term tritium distribution in released Fukushima water

Operators have pumped water to cool the nuclear reactors at the Fukushima Daiichi Nuclear Power Plant (FDNPP) since the accident in 2011 and treated this cooling water with the Advanced Liquid Processing System (ALPS), which is a state-of-the-art purification system that removes radioactive materials, except tritium.

As part of the water molecule, tritium radionuclide, with a half-life of 12.32 years, is very costly and difficult to remove. The ALPS-treated water was accumulating and stored at the FDNPP site and there is limited space to store this water. Therefore, in 2021, the Government of Japan announced a policy that included discharging the ALPS-treated water via an approximately one-kilometer-long tunnel into the ocean. Planned releases of the ALPS-treated water diluted with began in August 2023 and will be completed by 2050.

In a new numerical modeling study, researchers have revealed that the simulated increase in tritium concentration in the Pacific Ocean due to the tritium originating from the ALPS-treated water is about 0.1% or less than the tritium background concentration of 0.03−0.2 Bq/L in the vicinity of the site (within 25 km) and beyond.

Building Markets to Scale Carbon Management Solutions

Amid growing policy momentum, Carbon Management Solutions (CMS), including Carbon Capture, Utilization and Storage (CCUS), clean hydrogen, and emerging carbon markets, are gaining critical support. This report examines the evolving landscape of CMS, highlighting emerging value chains integration and novel business models.
