Webb detects carbon dioxide in exoplanet atmosphere
The NASA/ESA/CSA James Webb Space Telescope has found definitive evidence for carbon dioxide in the atmosphere of a gas giant planet orbiting a Sun-like star 700 light-years away. The result provides important insights into the composition and formation of the planet, and is indicative of Webb’s ability to also detect and measure carbon dioxide in the thinner atmospheres of smaller rocky planets.

Want to Live on Mars? Here's Where the Water is
When crewed missions begin to travel to Mars for the first time, they will need to be as self-sufficient as possible. Even when Mars and Earth are at the closest points in their orbits to each other every 26 months (known as “Opposition“), it can take six to nine months for a spacecraft to travel there. This makes resupply missions painfully impractical and means astronauts must pack plenty of supplies for the journey. They will also need to grow some of their food and leverage local resources to meet their needs, a process known as In-Situ Resource Utilization (ISRU).
