NASA Is Starting a U.S. Space Academy? Orbital Dogfighting and Starship Flight 14
Today In Space
This week, we're covering what's been trending in Space News for the last 5 days...and NASA HAS BEEN TASKED WITH BUILDING A U.S. SPACE ACADEMY! But how serious is this executive order and it's create a presidential commission? Could this be the start of our own Starfleet Academy or just the Presidents Legacy piece? We also get into the first U.S. military live-fly exercise in orbital dogfighting, and updates on where Starship Flight 14 stands. Gathered by our AI Assistant SKYE and reported by your human host Spaceman Alex! I'm Alex G. Orphanos, your space science podcast host and your favorite...

A German Commercial Rocket Reached Orbit From Norway | Swift's Rescue Failed, New Horizons Faces Cuts
Today In Space
This week, we're covering what's been trending in Space News for the last 8 days...and EUROPE FINALLY HAS ITS OWN RIDE TO ORBIT! A German company launched a commercial rocket to orbit from Norway — and almost nobody covered it, including SKYE on its first pass. We also get into NASA's failed rescue of the Swift telescope, and a nuclear-powered spacecraft at the edge of the solar system that's on the chopping block. Space News gathered by our AI Assistant SKYE and reported by your human host Spaceman Alex! I'm Alex G. Orphanos, your space science podcast host and your favorite mad...

There's Something Human About Stargazing | Bortle 1 Skies & Perspective | EP418
Today In Space
There's something human about stargazing. You don't even need to know what you're looking at. I just got back from Maine and about the most perfect dark skies you could ask for — a Bortle 1 or 2, against the Bortle 6 or 7 we get at Today In Space HQ outside Boston. Dark, clear skies like that makes you wonder what the night sky was to the early humans like the ancient Greeks & their Mythologies. These deep moments allow for some deep perspective. like what it's like a year since I was laid-off aka "terminated" and why the more AI work I do, the more I want to go do human things. Great...

Artemis Origin, Moon Flashes, and Artemis III! Space Talkers Artemis 2 RECAP PT2
Today In Space
The Space Talkers are back for part TWO, for a discussion about how Artemis was created, and some round-table talk about our favorite moments of Artemis II! We get into the space toilet that froze, the mental health protocols behind a crew locked in a capsule for days, the East Coast fireballs, why NASA canceled planned correction burns, and what all of it means for Artemis III. Along the way we talk telescopes, dark skies, Cherry Springs, and how this little community of space people found each other in the first place. Thank you to Matt, Caitlin, and Andrew for joining us live for this back...

Artemis, AI, and Stargazing | Space Talkers RETURN! Artemis 2 RECAP PT1
Today In Space
The Space Talkers joined forces again to breakdown the Artemis II mission. Anything Artemis Program-related means lots of excitement, and so naturally AI, Technology, and Stargazing come up as we unwrap this mission and what it means as we move towards the next Artemis mission (III) Today in Space brings the team together to recap Artemis II. This discussion is for anyone following NASA moon mission progress. We analyze the key milestones and what the upcoming flight path means for the future of lunar exploration, and what's happening here on Earth in the meantime. Thank you to Matt, Caitlin,...

I Wrote & Published a Book in 10 Months After Being Laid Off | The Return of Spaceman Alex
Today In Space
I got LAID OFF from my Engineering/Tech Day Job. 10 Months later, I've written and published my first book on 3D Printing. It's time to share that story... It's the Return of Spaceman Alex & Today in Space podcast! I share the process behind writing & publishing "The Book of Uncommon-Sense 3D Printing". If you are interested in how I managed to complete this project while navigating a major career change, this video is for you. Whether you follow my 3D printing advice or are just curious about my author journey, I hope this video provides some motivation. Writing a book taught me a lot...

NASA Moon Base Update & New Glenn Pad Anomaly for Blue Origin
Today In Space
NASA’s Moon Base plans just got a major update — and then Blue Origin had a serious New Glenn pad anomaly at LC-36 that could shake up the timeline for upcoming lunar missions. In this episode of Today In Space, we break down NASA’s latest Moon Base update, including new awards for lunar landers, terrain vehicles, lunar drones, and the next phase of Artemis-related infrastructure. We also react to the New Glenn pad anomaly during static-fire preparations, what it could mean for Blue Origin, the Artemis architecture, and the broader push to build a permanent human presence on the Moon....

info_outlineWe are joined by experts from Xometry, a company that many engineer's have grabbed instant quotes & custom parts on demand with CNC machining, 3D printing, and more. This week, we are joined by Mike Cavalieri and Greg Paulsen - both leaders at Xometry. Our guests are experts in rapid prototyping to full production and have helped big Space Companies like SpaceX, Blue Origin, NASA, and more when they need a reliable machine shop to make parts for space applications.
We discuss their origin stories, how 3D Printing can be helpful in Space applications, and what kinds of parts have been made for Aerospace. While they can't get too into the specifics, we get a great deep dive into how Xometry plays a big role in helping customers find unique advantages with 3D printing.
We also discuss big topics like Manufacturing in America, and how platforms like Xometry can help skilled machine shops in the US find customers using their powerful tools and data. When AI is combined with their skilled experts in many manufacturing methods, you get a powerful web of part makers and consumers that can help fill the gap on the feast or famine that is manufacturing.

Thank you to both Mike & Greg for joining us and sharing so much with us about what it takes to make parts for Aerospace in 3D printing but also many other traditional techniques.
