There’s a helpful concept we use to help understand what distance from a given star you might expect to find planets with liquid water on their surface – liquid water being essential for life as we know it. It’s called the habitable zone. Every star has a habitable zone, but where that zone lies is

We’re doing science at 17,500 miles per hour! The International Space Station is a state-of-the-art microgravity laboratory that is unlocking discoveries not possible on Earth, and helping us push farther into deep space. We’re testing technologies that are critical to our return to the Moon and great leap to Mars. Station research has contributed to
