NASA researchers are creating a spot colder than the vacuum of space inside the International Space Station. In 2018, a new atomic refrigerator will blast off for the space station. It’s called the Cold Atom Lab (CAL), and it can refrigerate matter to one ten billionth of a degree above... Read More

It has been known for some time that time in space affects astronauts’ vision. Post-flight vision changes have been reported by many astronauts after they spend time on the International Space Station. Many, but not all. But why are only certain people affected by spaceflight in this manner?’

If your favorite astronaut returns from space wearing horn-rim glasses and funny stockings, don’t be too disappointed. It’s all part of the job. And there’s a logical explanation. Among the challenges astronauts face during their stints on the International Space Station, farsightedness is fairly... Read More
