What if there are intelligent lifeforms elsewhere in the universe? And what if all we need to do to find them is to listen to the right radio frequency at the right time? That's what the scientists of SETI (Search for Extraterrestrial Intelligence) have been working on for decades. And that research got the Hollywood Glow-Up back in 1997 with Contact, starring Jodie Foster as SETI researcher Dr. Ellie Arroway. Because if we were alone in the Universe, wouldn't that be such a waste of space?

It's a bird? It's a plane? Its a guy pretending to be a bird?? We have a very odd aircraft in the collection. It's an ultralight. Small, highly maneuverable and based off the wings hang gliders use to jump off mountains, this particular ultralight was used to help birds migrate. And it starred in the movie in the '90s! When we heard that we were like, say more please.

Back in the 'Golden Age' of air travel in the 50s, 60s and 70s going on a trip in an airplane was an event. On those flights you would often get a little souvenir of your air travel; a deck of cards, a little toy, a trading card, captain's wings and a hat for your little tyke. It was a way for you to show off to your friends and for the airline to keep themselves top of mind for your next airline purchase. Like a lot of things from the era, deregulation came along in 1978 and completely changed the flight experience. Now that an airline can offer you a cheap ticket, they're not trying to get your business through tchotchkes. But! There are still some airlines giving out swag. Some of it you have to pony up for first class and some of it you have to ask for. We asked for it (because the AirSpace budget sadly doesn't include first class tickets).

Over six missions, the Apollo astronauts collected and brought back 842 pounds of Lunar samples. Most of those Moon rocks were put aside for science, but some were earmarked for things like touch rocks (like we have at NASM) or educational disks (which you might have seen if you had a particularly cool science teacher growing up) and to countries and states as diplomatic gifts. But who decides what rocks go where? And how in the heck did the National Cathedral get a rock to put in a stained glass window??

There are a lot of air and space celebrities; pilots, astronauts, engineers, etc etc. But there's another category of celebrities that are famous for other things but also have surprising ties to air or space. Today we're talking about three of those; a famous tv chef who also helped create a shark repellant for aviators and spacecraft, an actor from Hollywood's golden years who invented the basis for wifi, and an aerospace engineer who worked on Apollo and more--and also has a pretty famous kid. Stay tuned to the end for a special celebrity guest.

When the Chandra X-Ray Observatory launched 25 years ago, it showed us our universe in a whole new light (literally). From the remnants of exploded stars to Jupiter's auroras, Chandra has shown us so many beautiful and scientifically important sights. Even after a quarter decade this unique telescope is still giving us new data about black holes and whirling neutron stars and all the things out in space that give off x-rays.

The city of Roswell, New Mexico is kind of in the middle of nowhere. Out in the dessert west of Texas, this small oasis in the dessert was first home to indigenous peoples, then cowboys, ranching and farming and then the military before becoming the crash site of a possible UFO in 1947. That story took on a life of it's own and by the time the Army came out with an official explaination in 1997, the myths had stuck. Today, Roswell is still a farming and ranching community but 'the incident' as it's known bred a tourism economy based on aliens. From the flying saucer McDonalds, to the International UFO Museum and Research Center, and the annual UFO festival; Roswell is a unique space-y destination all its own.

We're joined by Dr. Emily Margolis, Curator of Contemporary Spaceflight
