We’re hard at work on Season 5 (launching this September!) but before then, we’re giving you a second bite at a topic we spent a long time thinking about this year: what’s in a name? Earlier this season we explored how planetary bodies and their geological features get named. We also recorded an explainer on how NASA names their spacecraft, but we just didn’t have time for it in the original episode. So, what do Snoopy, Spider, and Gumdrop have in common? Find out in this bonus episode!

A brief treatise on the historic tools used in the construction and restoration of the National Air and Space Museum’s Standard J-1 aircraft.

Earl Swift sought out the full story of the LRV’s origins, development, and traverses  in his new book “Across the Airless Wilds.” In this interview, he tells us he believes the LRV changed everything about the Apollo program.

The 1900 Olympic Games, held in Paris as part of the Exposition Universelle (World’s Fair), was the only year in which ballooning was an official event.

Every rock can tell us a story, once we know how to read it. The sample designated 15016 tells a story of how two visitors from another world happened to collect it.

We have a flair for the dramatic here at AirSpace (Who… US?!). And we’d be lying if we told you we don’t occasionally daydream about the end of the world. But, like, scientifically speaking. We’ve seen plenty of sci-fi depictions of what the end might look like, but what will actually happen when the Sun engulfs the Earth? And what does the “end of the universe” even mean? To dissect these grim questions, we’re diving into a sci-fi series that offers a lot of hopeful examples of humanity’s perseverance: "Doctor Who."

Space history curator Michael Neufeld tells the story of Gus Grissom's suborbital flight in July 1961 and the blown hatch that resulted in the sinking of his Mercury capsule.

Wally Funk is finally going to space. After being the youngest of the female pilots tested by Dr. Lovelace, Funk will become the oldest person to fly into space at age 82.

Welding and fabrication specialist Meghann Girard takes us through the way she combined contemporary technology with traditional metalworking techniques to fabricate missing parts from our Lincoln-Standard H.S.

Earth’s twin or Earth’s evil twin? It depends on who you ask. And no, we’re NOT talking about Mars (take a break from the news cycle, Ingenuity). We’re talking about the beautiful, enigmatic, and hot (VERY hot) VENUS. Not one but TWO NASA spacecraft are heading to Venus later this decade.
