Ariel Tweto is a self-proclaimed adrenaline junkie, but getting her blood pumping isn’t the only reason she flies. Last month, Tweto flew for a purpose — to raise awareness about aviation — as she participated in her first air race, the Air Race Classic.

At the end of the NASA Cassini spacecraft's 13-year mission, National Air and Space Museum scientists and educators are reflecting on what this mission has meant to them.

I think it surprises a lot of people that a mission as successful as the Cassini-Huygens Mission would be terminated on purpose. Not just shutting the spacecraft off, but terminated with such style by sending it on a destructive dive into Saturn’s atmosphere. Cassini will burn up and be destroyed in a similar way that a meteorite is broken up in Earth’s atmosphere.

Can you imagine your teacher being chosen to be a NASA astronaut? Students in Joe Acaba’s secondary math and science classes in Florida can. Acaba was one of 11 candidates selected for the 2004 astronaut class. The process to become an astronaut is one of the most competitive and highly selective processes in the world. Do you think you have what it takes?

Gallipoli sets a classic tale of innocence lost in war during the World War I (WWI) Gallipoli Campaign against the Ottoman Empire (modern-day Turkey). One of the few Hollywood movies to illustrate that WWI took place not only on the Western Front in France, Gallipoli tells the story of this major campaign through the experience of several Australian young men who travel halfway around the globe to fight for their country.

“The Millionaires’ Unit” was a moniker given by the New York press to group of wealthy Yale students who formed a private air militia in 1916 to learn to fly in preparation for the United States entering World War I. Author and historian Marc Wortman wrote a book about them in 2006, and a college friend of mine, Ron King, saw his grandfather’s face on the book’s cover. The archival material seemed rich, and we decided to make a documentary.

You’ve probably heard a lot about the upcoming solar eclipse on August 21, 2017. You may have also heard that solar eclipses are a rare phenomenon. Total solar eclipses (when the Moon completely covers the Sun) occur approximately once every year and a half—that works out to two to three eclipses of all kinds each year and only two total solar eclipses every three years. This might not sound so rare to you, but the shadow the Moon casts on the Earth is, at most, 274 kilometers (170 miles) across. That shadow covers roughly 37,015 square kilometers (23,000 square miles) at any one time: only 0.01% of the total surface area of Earth! At most, a total eclipse can last about 7 minutes in one place, so the chances of a total solar eclipse coming to you during your lifetime are pretty low. For instance, the last total solar eclipse that passed through Washington, D.C. was in 1478, and the next one is not coming until 2444!

Here we are, less than one week until a total solar eclipse crosses the United States. For the past three years, my excitement has been building, and all of my eclipse-chaser friends have been saying, “You HAVE to go see totality!” The path of totality (the narrow region where the Sun will appear totally blocked) is relatively convenient for North Americans, but many people won’t be able to travel and witness the total phase of the eclipse.
