NASA Announces CHAPEA Crew for Year-Long Mars Mission Simulation

Four research volunteers will soon participate in NASA’s year-long simulation of a Mars mission inside a habitat at the agency’s Johnson Space Center in Houston. This mission will provide NASA with foundational data to inform human exploration of the Moon, Mars, and beyond.

Ross Elder, Ellen Ellis, Matthew Montgomery, and James Spicer enter into the 1,700-square-foot Mars Dune Alpha habitat on Sunday, Oct. 19, to begin their mission. The team will live and work like astronauts for 378 days, concluding their mission on Oct. 31, 2026. Emily Phillips and Laura Marie serve as the mission’s alternate crew members.

Through a series of Earth-based missions called CHAPEA (Crew Health and Performance Exploration Analog), carried out in the 3D-printed habitat, NASA aims to evaluate certain human health and performance factors ahead of future Mars missions. The crew will undergo realistic resource limitations, equipment failures, communication delays, isolation and confinement, and other stressors, along with simulated high-tempo extravehicular activities. These scenarios allow NASA to make informed trades between risks and interventions for long-duration exploration missions.

An Apollo 8 Christmas Dinner Surprise: Turkey and Gravy Make Space History

On Christmas Day in 1968, the three-man Apollo 8 crew of Frank Borman, Jim Lovell, and Bill Anders found a surprise in their food locker: a specially packed Christmas dinner wrapped in foil and decorated with red and green ribbons. Something as simple as a “home-cooked meal,” or as close as NASA could get for a spaceflight at the time, greatly improved the crew’s morale and appetite. More importantly, the meal marked a turning point in space food history.

Rising deep-ocean oxygen levels likely opened up new marine habitats and spurred speciation

Some 390 million years ago in the ancient ocean, marine animals began colonizing depths previously uninhabited. New research indicates this underwater migration occurred in response to a permanent increase in deep-ocean oxygen, driven by the above-ground spread of woody plants—precursors to Earth’s first forests.

That rise in oxygen coincided with a period of remarkable diversification among fish with jaws—the ancestors of most vertebrates alive today. The finding suggests that oxygenation might have shaped evolutionary patterns among prehistoric species.

The study is published in the journal Proceedings of the National Academy of Sciences.

Did Elon Musk Just KILL the Model Y L in America?

Questions to inspire discussion.

🤖 Q: What is Tesla’s vision for autonomous vehicles? A: Tesla is prioritizing a robo taxi future with Cybercab and potentially Robovan, likely to focus on producing robo vehicles over traditional cars in the near future.

📊 Q: How does the Model Y L fit into Tesla’s robotaxi plans? A: The Model Y L would be a good fit for the robo taxi network, offering a bigger car with more versatility that people want, even if they don’t need the space, and would be a hot seller in the US market.

Tesla’s Full Self-Driving Progress.

🚀 Q: How close is Tesla to achieving full self-driving? A: With version 14 of FSD almost complete and version 15 likely to be the final needed version within a year, Tesla is expected to fully commit to the robo taxi future.

🏢 Q: How has Tesla’s leadership approached the robotaxi strategy? A: Tesla’s executives previously resisted Elon Musk’s push to bet the company on robo taxis, but are now likely to fully commit given the progress in FSD development.

SpaceX’s Mars Breakthrough — What No One’s Talking About!

SpaceX is making significant progress towards establishing a human presence on Mars, with a major contract, advancements in technology, and plans for infrastructure development, potentially giving them a lead over competitors and raising questions about the future of space exploration and ownership ##

## Questions to inspire discussion.

Mars Exploration and Infrastructure.

🚀 Q: What is SpaceX’s breakthrough in Mars exploration? A: SpaceX’s Starship secured its first paying customer for Mars payloads: the Italian Space Agency, in a deal worth hundreds of millions of dollars.

🔬 Q: What experiments will the Italian Space Agency conduct on Mars? A: The payload includes plant growth, radiation, and local climate monitoring experiments, collecting data during the 6-month flight and on Mars’ surface.

🤖 Q: How will robots assist in Mars exploration? A: SpaceX plans to send 1,000–2,000 Optimus robots to Mars to fix rovers, run experiments, maintain equipment, and scout locations for future missions.

First 3D-Printed Home Made Primarily From Soil is Built in Japan–Ditching Unsustainable Concrete

Collaborating with robotics engineers and Italian 3D printer manufacturers, a Japanese company is building “homes of earth” made primarily from soil.

Utilizing AI technology from design through construction, Lib Work, Ltd. completed their first 3D-printed earth home in Yamaga, Kumamoto on July 22, calling their creative process “uncharted territory where tradition and convention offered no guide”

While the automotive industry has undergone rapid transformation through technological advances, the housing industry has seen virtually no fundamental innovation in construction methods, materials, or structures for over 50 years.
