    Why Artemis II Was Scrubbed Until March (Now April) | NASA's Hydrogen Problem Explained

    This week on Today In Space...space nerds leave Florida disappointed as Artemis II is scrubbed until March (Now no earlier than April) — and cryogenic hydrogen does what it does best: leak. In this episode, we break down: Why liquid cryogenic hydrogen is both an incredible and deeply frustrating rocket fuel How Artemis I scrubbed three times in 2022 due to hydrogen leaks The forgotten history of the "Summer of Hydrogen" (1990) during the Space Shuttle era Why SLS inherits many of the same strengths — and weaknesses — as the Space Shuttle What this means for Artemis II launch timing in 2026 Hydrogen rockets are powerful, elegant, and environmentally cleaner — but they are also notoriously fickle. If you want to understand why scrubs are normal, why patience is required, and why Artemis II will eventually fly, this episode is for you. #Artemis2 #NASAArtemis #SpaceLaunchSystem #ArtemisScrub #TodayInSpace We'd like to thank our sponsors: AG3D Printing (go to ag3d-printing.com to learn more & start 3D printing today!)

    Crew 11 is Home, A New Hope for NASA and the US Space Program

    In episode 402 of Today In Space, Alex G Orphanos discusses the rapid return of NASA's Crew 11 due to a medical emergency, highlighting NASA's swift response.  The crew, including astronauts from NASA, JAXA, and Roscosmos, safely undocked from the International Space Station, Reentry plash down off the coast of San Diego. Alex also announces the launch of our Substack newsletter, offering updates on space exploration, 3D printing, Al, and technology.   We close the episode with clips from our live coverage of the Crew 11 undocking. #SpaceMedicine #NASA #SpaceSafety #HumanSpaceflight #TodayInSpace We'd like to thank our sponsors: AG3D Printing (go to ag3d-printing.com to learn more & start 3D printing today!)

    NASA Sending Crew 11 Home Early Jan 14th | Astronaut Med Alert Conference from LIVE Hangout Jan 8th

    This week has been BUSY with activity in Low Earth Orbit on the Space Station! This episode is a recap from our LIVE Hangout broadcast on social media during NASA's International Space Station Update. We hear from the new NASA Administrator (Jared Isaacman), the Associate Administrator (Amit Kshatriya), and the Chief Space Medical Officer (Dr. James D. Polk) as they answer questions from NASA HQ in Washington, D.C. as the ISS operation teams at JSC in Houston were prepping Crew 11 to come home.  Hear my thoughts at the start and close - this conference was really good and a sign of the kind of leadership Jared Isaacman is bringing to NASA. One major takeaway, aside from wishing the now stable Astronaut gets home safetly, is that NASA really has a good head on it's shoulders. There is a lot of work to do - but in this I feel confident there are good winds of change under NASA's wings. Looking forward to the rest of 2026! #SpaceMedicine #NASA #SpaceSafety #HumanSpaceflight #TodayInSpace Timestamps: 00:00 ISS Update and Initial Reactions 02:04 Background and Initial Information 08:04 NASA's Response and Transparency 08:28 Details of the Medical Incident 09:56 Q&A Session with NASA Officials 13:23 Further Questions and Clarifications 19:20 Crew's Training and Medical Capabilities 32:10 Impact on ISS Operations and Future Missions 50:19 Final Thoughts and Next Steps We'd like to thank our sponsors: AG3D Printing (go to ag3d-printing.com to learn more & start 3D printing today!)

  6. SpaceX is Finally Going Public?!? The Space Conundrum STRIKES BACK!

    SpaceX is Finally Going Public?!? The Space Conundrum STRIKES BACK!

    In this episode, Alex uses a scientific approach to combat the emotional rollercoaster this past week has been since Mr. Musk has confirmed SpaceX is going Public! The Space Conundrum strikes again - and it's leaving many to wonder: Why Now? Listen to this episode if you'd like to learn more and explore: What is Elon Musk Thinking, taking SpaceX from an independent private company and trading it on the US stock exchange? What does an IPO mean for SpaceX? Does this mean "SpaceX's Mission to Mars" is over? What are the upsides to SpaceX going public? We're going to give our answer to all of those questions and I'll share my thoughts on this major piece of news. Just another day in the Space Conundrum - but it definitely wasn't on my 2025 or 2026 space bingo card. By the end of the video - we want to hear from YOU! What do you think?? Are you excited? Scared?? Or Both??!! We'd love to hear what you think in the comments or by emailing us at todayinspacepodcast@gmail.com.

    The Road to NASA Administrator | Jared Isaacman Passes Senate Committee AGAIN

    Jared Isaacman, previously chosen as the President's pick for NASA Administrator in March 2025, faced the Senate committee hearing AGAIN to discuss his qualifications and potential conflicts of interest before leading the American Space Program. The past year of delay was due to political nonsense, leaving NASA without leadership that whole time. Mr. Isaacman is an entrepreneur, 2 mission astronaut commander, philanthropist, and father who has a unique leadership style. He returned to the Senate Committee sharper than ever! We listen in on the live Senate Committee meeting for some Q&A and talk about the state of NASA. Not to mention, how much NASA is in need of clear leadership and direction after almost a year of delay. Today In Space is PRO-Jared! Go get 'em Rook! As of December 9th, 2025 - Mr. Isaacman has passed the Senate Committee and is on to full Senate Vote! Enjoy this bit of LIVE hangout from the past week We'd love to hear what you think in the comments or by emailing us at todayinspacepodcast@gmail.com.

  8. NASA & Interstellar 3I-ATLAS | Recap w/ My Thoughts & Press Q&A

    25/11/2025

    NASA & Interstellar 3I-ATLAS | Recap w/ My Thoughts & Press Q&A

    We went live for the NASA broadcast of the release of images of the Interplanetary "comet" 3I-Atlas, which was delayed due to the government shutdown. As the cultural curiosity surrounding 3I-ATLAS went viral during the poorly timed government shutdown, it was a unique opportunity for NASA to do what it does best. Share data and spend a little more time with the actual experts to explore that curiosity and dig deeper into what we found.  Unfortunately, it feels as though the government shutdown and funding cuts proposed by the current President's cabinet was more of an influence on this 3I-ATLAS review than curiosity was. If you wanted to know how I feel about this you can rewatch it live.  Two major themes for me: - Don't be an intellectual bully. There are curious people out there who are not trolling you (NASA). Talk to those people without demeaning their curiosity - The definition of a "Comet" is vague and outdated. Just like Pluto needed to be reclassified as a dwarf planet, we need a better term for these icy objects.  Would love to know what you think!
