NASA researchers use balloon flights to do scientific experiments or test out equipment for future space missions. At 21 to 25 miles (34 to 40 kilometers) in the air, where these balloons fly, Earth's atmosphere is extremely thin. This means equipment on board the balloon can get a clear view of outer space.
"The super-pressure balloon technology is a real game-changer for conducting cutting-edge science at the end of space," says Debbie Fairbrother. She heads NASA's Balloon Program Office in Virginia.
These scientific balloons are made of a thin plastic film that's just 0.0008 inches (0.02 millimeters) thick. Called polyethylene, it's similar to sandwich wrap. But that flimsy-looking skin stretches around an enormous volume of air. The most common balloons flown by NASA are 40 million cubic feet in volume-equal to 195 Goodyear blimps. These balloons are about 40 stories tall. NASA also launches balloons that are smaller than this, or even larger.

Who's Your Cousin?
The great apes are among the most popular animals in most zoos. Their actions, facial expressions, and family life remind us so much of ourselves. Have you ever wondered, though, how we might look to them?
Is it possible to die of boredom?
To figure out if we can die of boredom, we first have to understand what boredom is. For help, we called James Danckert, a psychologist who studies boredom at the University of Waterloo in Canada.
THE PROBLEM WITH PALM OIL
Palm oil is all around you. It’s in sugary snacks like cookies and candy bars. It’s in lipstick and shampoo and pet food.

HUMANS AREN’T THE ONLY PRIMATES THAT USE MEDICATION.
THE LEFT OVERS
A lot has happened for modern humans to get to this point. We lost most of our hair, learned how to make tools, established civilizations, sent a person to the Moon, and invented artificial intelligence. Whew! With all of these changes, our bodies have changed, too. It’s only taken us about six million years.
SO, WHAT IS A PRIMATE?
What do you have in common with the aye-aye, sifaka, siamang, and potto? If you said your collarbone, you re probably a primatologist—a person who studies primates. If you’re not, read on.
