In a recent contest, teams of researchers competed to see who could train an AI model to best pilot a spaceship. The results suggest that an era of autonomous space exploration may be closer than we think.

Elon Just Made Tesla Unstoppable
Questions to inspire discussion.
đ Q: How might Elon Muskâs diverse projects contribute to Teslaâs value? A: Muskâs involvement in AI, energy, transportation, and communication through projects like Tesla, SpaceX, and Neuralink demonstrates his capacity to make progress on multiple fronts, potentially creating significant value for Tesla.
Political Involvement and Economic Strategy.
đïž Q: Why is Elon Musk getting involved in politics? A: Muskâs political involvement aims to create a better political system on Earth, addressing the unsustainability of US government spending and debt to avoid a fiscal doom loop.
đ Q: What is Muskâs strategy to improve the US economy? A: Musk plans to accelerate GDP growth through AI-driven growth, humanoid bots, and reducing government spending and waste, potentially breaking free from the constant 7% growth line of the US stock market.
đ° Q: How could reducing government spending benefit the economy? A: By cutting wasteful spending and implementing a balanced budget requirement, the US could potentially grow its economy faster than its spending, reducing interest costs and freeing up money for other investments.

Mining the Moon begins: US firmâs robot to extract rare helium-3 and launch payloads back to Earth for futuristic energy use
In a bold move that could transform the future of clean energy and quantum computing, a Seattle-based startup, Interlune, is taking the first steps toward mining the Moon for a rare isotope called helium-3. This new venture has the potential to challenge the boundaries of technology, as well as the frameworks for space exploration and international resource management.
âWeâre Finally Fast Enoughâ: Nuclear Propulsion and Solar Sails Could Blast a Spacecraft to Sedna in Just 7 Years
IN A NUTSHELL đ Scientists are developing two experimental propulsion methodsânuclear fusion and solar sailsâto reach Sedna. đ Sedna, named after the Inuit goddess of the ocean, offers a rare chance to explore the outer solar system. đŹ Exploring Sedna could unlock insights into the early solar system and the formation of celestial bodies. đ
Extraterrestrial Habitats: Bioplastics for Life Beyond Earth
If humans are ever going to live beyond Earth, theyâll need to construct habitats. But transporting enough industrial material to create livable spaces would be incredibly challenging and expensive. Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) think thereâs a better way, through biology.
An international team of researchers led by Robin Wordsworth, the Gordon McKay Professor of Environmental Science and Engineering and Professor of Earth and Planetary Sciences, have demonstrated that they can grow green algae inside shelters made out of bioplastics in Mars-like conditions. The experiments are a first step toward designing sustainable habitats in space that wonât require bringing materials from Earth.
In lab experiments that recreated the thin atmosphere of Mars, Wordsworthâs team grew a common type of green algae called Dunaliella tertiolecta. The algae thrived inside a 3D-printed growth chamber made from a bioplastic called polylactic acid, which was able to block UV radiation while transmitting enough light to allow the algae to photosynthesize.
The algae was kept under a Mars-like 600 Pascals of atmospheric pressure â over 100 times lower than Earthâs â and in a carbon dioxide-rich environment, as opposed to mostly nitrogen and oxygen like on Earth. Liquid water cannot exist at such low pressures, but the bioplastic chamber created a pressure gradient that stabilized water within it. The experiments point to bioplastics as potentially key to creating renewable systems for maintaining life in a lifeless environment.
The concept the researchers demonstrated is closer to how organisms grow naturally on Earth, and it contrasts with an industrial approach using materials that are costly to manufacture and recycle.
