Where does space begin? Well, it depends. There’s no sharp boundary that marks the end of atmosphere and beginning of space. But no matter where you draw the line in the sand — or the air — Earth’s atmosphere is full of all kinds of interesting stuff. That’s why scientists like Doug Rowland are studying its many layers: https://climate.nasa.gov/news/2919/ea... Link to download this video: https://images.nasa.gov/details/Where...

Thanks to a global effort to regulate ozone-depleting substances, the ozone hole is showing signs of recovery and is projected to return to a healthy level by mid-century. However, at NASA, scientists continue to monitor its progress. @NASAGoddard's Qing Liang explains more.

How do planets get their names? With the exception of Earth, the planets in our solar system were named after Greek or Roman gods. Today, the job of naming things in space falls to the International Astronomical Union (IAU), the internationally recognized authority for naming celestial bodies and their surface features. NASA scientist Dr. Henry Throop explains more. Link to download this video: https://go.nasa.gov/3Qc2qMI

We know the Moon contains water, but, could future astronauts access and make use of it? That’s the goal. At NASA, we’re actively trying to answer that question. Once it lands at the lunar south pole, our PRIME-1 — Polar Resources Ice Mining Experiment-1 – will robotically sample and analyze ice from beneath the lunar surface, contributing to our search for water on the Moon: https://go.nasa.gov/2QygCmF

When it comes to space, humans and robots go way back. We rely heavily on our mechanical friends to perform tasks that are too dangerous, difficult, or out of reach for us humans. We’re even working on a new generation of robots that will help us explore in advanced and novel ways. Learn more about the CADRE—Cooperative Autonomous Distributed Robotic Exploration—project and how this new network of mini rovers could enable future self-guided robotic exploration of the Moon, Mars, and beyond. https://go.nasa.gov/3k5EuZx Link to download this video: https://images.nasa.gov/details/Do%20...
