Recorded on Sunday 29 March, 2026:

Just days before the first human mission to the Moon in 53 years, Talking Space returns to discuss preflight activities and the changes within NASA’s Artemis lunar program. Mark Ratterman discusses his thoughts on the growth of activity in and around the Kennedy Space Center (KSC) since the days of the Space Shuttle program, and reflects on both the L- 3 launch press conference, the Artemis II Crew arrival at KSC for the launch and their question-and-answer session with the press from their quarantine quarters at KSC.

Since Jared Isaacman has taken the reigns at NASA, the Artemis Lunar Program architecture has undergone significant alterations. NASA has restructured the first few Artemis missions and has decided to put the Lunar Gateway on hold (not cancelling the program outright as some outlets have reported) in order to pursue the establishment of a permanent lunar base in three phases starting in 2027. We discuss the plan outlined in the NASA Ignition presentations last week, their features, cost, and the likelihood that NASA will land a human expedition on the Moon before the agency’s self-imposed deadline of 2028.

Talking Space will be watching closely the events of Artemis II and nest time will bring you reports and reflections surrounding the progress of the first human mission to the Moon since the Apollo 17 flight in December of 1972.

In 2012, following the end of the Space Transportation System program, NASA faced the monumental task of finding permanent homes for the three remaining Space Shuttle Orbiters—so that their incredible stories could be preserved and shared with the public.

After a lengthy and sometimes contentious selection process, the three operational orbiters—Discovery, Atlantis, and Endeavour—along with the prototype Enterprise, were officially retired and transported to their new homes amid much celebration. These irreplaceable artifacts of American space history now serve as centerpieces in four major museums across the country, inspiring millions of visitors each year.

One notable omission from the final list was Houston, Texas—home to NASA’s Johnson Space Center. While the city did not receive one of the orbiters, it was awarded a Shuttle Carrier Aircraft and a full-scale model orbiter, which allows visitors to explore a replica of the Shuttle's interior.

That should have been the end of the story—but it wasn’t.

In a surprising twist, Texas Senators John Cornyn and Ted Cruz inserted a provision into the recently passed Reconciliation Act, also known as “The Big Beautiful Bill Act" that calls for relocating Space Shuttle Discovery from its current home at the Smithsonian National Air and Space Museum’s Steven F. Udvar-Hazy Center in Chantilly, Virginia, to Houston.

Is this bold attempt at “Shuttle Rustling” even viable?

To find out, we spoke with Joe Stief, the founder of Keep the Shuttle, a grassroots campaign working to prevent Discovery’s relocation. We discuss his efforts, what’s at stake, and the broader implications this move could have for the future of artifacts held by national museums.

The OSIRIS-APEX mission, an extension of the wildly successful OSIRIS-REx mission, is set to rendezvous with Asteroid 99942 Apophis in April 2029. This mission takes full advantage of the OSIRIS-REx spacecraft, which still has plenty of fuel and is totally healthy after delivering samples from Asteroid Bennu to Earth on 24 September, 2023.

OSIRIS-APEX will closely observe Apophis as the asteroid makes a remarkably close flyby of Earth, coming within 32,000 kilometers (20,000 miles) – closer than some Earth-orbiting satellites. The mission's primary objectives are to study how Earth's gravitational pull affects the orbit of Apophis, its spin, and surface features.

However, the mission is in peril. The proposed Presidential Budget Request for Fiscal Year 2026 budget calls for the cancellation of OSIRIS-APEX, despite its low cost and the scientific value it offers as an extended mission using an already existing and proven spacecraft.

On this episode of Talking Space, we're joined by Dr. Dani Mendoza DellaGiustina, Principal Investigator for the OSIRIS-APEX mission and Assistant Professor at the University of Arizona's Lunar and Planetary Laboratory. We'll delve into the mission's goals, the reasons given behind its potential cancellation in the 2026 NASA Budget, and the options available should the 2026 budget be approved by Congress, a budget that cancels this ambitious mission.

Episode 1701: Talking Space returns after a hiatus to discuss the landing attempts by the NASA Commercial Lunar Payload Services program. First a successful soft landing of the Firefly Aerospace Blue Ghost 1 mission on the plans of Mare Crisium. Then a much more perilous landing attempt for the Intuitive Machines "Athena" lander, trying to land its suite of science and technology demonstrations closer to the Lunar South Pole than any other mission to date, with some mixed results. We also mention that Japan's ispace is set to try a lunar landing on 6 June.

We then focused on the Expedition 72 / 73 handover at the International Space Station and took one more look at the Crew-9 Mission's saga in the mainstream press with a reminder: Butch Wilmore and Suni Williams were never "stuck" or "stranded" on the ISS, and never needed to be "rescued."

Our Mark Ratterman also reminds all that the NASA Spinoff catalog for 2025 is available for download.

If at first, you don't succeed... try, try again out at Boca Chica Texas for the SpaceX Starship with Integrated Flight Test 8. Alas, the same result as Mission 7 with debris scattering over the skies of Caribbean Islands and air traffic having to be diverted out of the area, quickly. We discuss the incident and the possible future of the program.

We end the program with a plea, especially for our friends in the United States. Due to current goings-on within the US government, both NASA's personnel and budget are poised to be cut drastically. A 50 % cut in the NASA science budget is not outside the realm of possibility. The impact would be catastrophic, causing long-established science investigations to shut down, and crippling the start of new missions.

Very rarely do we go into activist mode, but this is one of those times where it is required. If you care for your space program, tell your elected representatives. Don't know how to contact them? Here's a guide via Congress.gov

It was September 9, 2009; aka 09/09/09.

That was the easy-to-remember air date of the first episode of Talking Space. The Space Shuttle era was ending. As far as most of the public was concerned, that represented the death knell for the U.S. Space Program. But Gene, Mark and Sawyer knew better, and they were trying to figure out how to best spread the word that all was not lost.

Thus, Talking Space was born. And what a ride it’s been.

In Part 2 of this retrospective (Part 1 can be found here), the team reveals:

• The role of audience feedback – pros and cons, and the methods by which we receive it (and don’t, despite our best efforts);
• Our social media follies;
• The behind-the-scenes scrambles to cover launch anomalies;
• The proven importance of dissimilar redundancy, as well as interoperability;
• How we’ve dealt with the occasional bouts of podcast burnout over the last 15 years, because sometimes we just get tired, you know? And sometimes, Life just gets in the way. Those are the times we’re glad we’re not doing this podcasting stuff alone.

And we also talk about how much we value feedback from you, our listeners – even when you let us know you do not particularly agree with us.

Be sure to let us know your thoughts on the topics we discuss. You can always reach us at mailbag@TalkingSpaceOnline.com .

It was September 9, 2009; aka 09/09/09.

That was the easy-to-remember air date of the first episode of Talking Space. The Space Shuttle era was ending. For most casual observers, that represented the death knell for the U.S. Space Program. But Gene, Mark and Sawyer knew better, and they were trying to figure out how to best spread the word that all was not lost.

Back then, there were basically only three places to publish a podcast: iTunes, Yahoo and your own website (probably made with Wordpress). Apple didn’t launch its first standalone Apple Podcasts mobile app until 2012. The app was later pre-installed with iOS beginning October 2014.

Now, you can listen to Talking Space on any of what seems like dozens of available podcast aggregation apps.

So, as our gift to you, you get to hear us talk about ourselves for a change – like it or not. Yay!

This time around, our entire on-air team (as it existed when this episode was recorded on September 19, 2023) lets their collective hair down to celebrate and reminisce about how Talking Space got started back in those Wild West days of podcasting. We also discuss how each of us came to find a way to be a part of it. We’ll reveal the "challenging" episodes, the ones that caused us joy, the occasionally stressful times, and the often very rewarding times.

Listen in as we share behind-the-scenes stories of covering historic events, interviewing legendary astronauts, and navigating the ever-evolving world of space exploration.

Discover how Talking Space has grown and adapted over the years, embracing new formats and audiences while staying true to its mission of delivering in-depth analysis and commentary. Whether you're a long-time listener or new to the podcast, this episode offers a unique glimpse into the passion and dedication that drives the Talking Space team.

Don't miss Part 1 of this engaging and nostalgic look back at the past 14 years of Talking Space.

And then, stay tuned for Part 2, coming soon, where the conversation continues!

Environmental regulators are beginning to clamp down on Starbase. The big question is: Do these enforcement actions have enough significance to force the FAA to delay launch activities at Boca Chica?

Some troubling headlines appeared on CNBC.com on Monday, August 12, 2024 concerning SpaceX’s alleged issues regarding compliance with environmental regulations that govern their activities at the Starbase facility in Boca Chica, Texas.

The story by Lora Kolodny alleges that “Elon Musk’s SpaceX violated environmental regulations by repeatedly releasing pollutants into or near bodies of water in Texas, a state agency said in a notice of violation focused on the company’s water deluge system at its Starbase launch facility.

“The notice from the Texas Commission on Environmental Quality (TCEQ) last week came five months after the Environmental Protection Agency Region 6 office, which covers Texas and surrounding states, had also informed SpaceX that it violated the Clean Water Act with the same type of activity.”

SpaceX finally submitted an application for an Industrial Wastewater Individual Permit on July 1, 2024. It was later revised, and the revised application was submitted August 14, 2024.

Beginning at 45:20 of this episode we discuss the following: SpaceX posted a response on X in the afternoon of August 12. It dubbed the CNBC story “factually inaccurate,” and revealed additional interesting information that was previously unknown to us.

We’re devoting this looonng episode (sorry!) to an analysis of these developments, and Eric Roesch is back with us to help give it all the once-over. And you know that wherever Eric is, a controversial, SpaceX-related environmental issue can’t be far behind. Among the topics we’ll discuss:

• What exactly happened here?
• The classic question: What did SpaceX know, and when did they know it?
• Do these enforcement actions have enough significance to force the FAA to delay launch activities at Boca Chica?
• How much worse can SpaceX make it by continuing to use the water deluge system before a permit is issued?
• What are the potential consequences for these violations? Could anyone actually go to jail?
• In SpaceX’s response post on X, why don’t some of SpaceX’s assertions make sense?
• Why did the FAA on Monday (the same day the CNBC story broke) cancel previously scheduled public hearings on the new draft Environmental Assessment for Boca Chica which requests a higher launch cadence and use of a bigger, more powerful and louder version of Starship than is currently in use?

Boca Chica OLM water deluge system test on July 27, 2023: SpaceX/X

NASA has tried to get Extra Vehicular Activity Number Ninety underway since June 13th. The first attempt was thwarted by a space suit comfort issue, the second by a water leak that created a blizzard of ice inside the Quest airlock. Are the Shuttle-Era Extra Vehicular Mobility Units (EMU) or space suits finally showing their age? Also, what about Collins Aerospace and their recent withdrawal from their NASA contract to build the next generation of space suits for the ISS and the Artemis Lunar Program when they indicated back in February that all was going well? We discuss.

On June 17th, the FAA held a virtual public hearing to receive comments concerning SpaceX’s plans to use Launch Complex 39-A and NASA’s Kennedy Space Center to support Starship Super Heavy Launches. We discuss what occurred during the session and the fallout from statements put into the record by both Blue Origin and United Launch Alliance.

Talking Space continues our Boeing Space CST-100 Starliner Crewed Flight Test coverage. The team continues to examine the “Starliner is Stuck at the ISS” misconceptions and asks what NASA & Boeing Space could have done to alleviate such headlines. We also look at a detailed explanation posted on Twitter from Jim May, a Boeing Engineer who was part of the NASA-TV coverage, of why “Calypso” remains on the ISS. The basis of his discussion comes from the actual NASA flight certification plan. Heather Smith mentions the observations of a NASA flight director and his assessment of how Starliner performed during its first actual safe-haven exercise.

All this and more in this edition of Talking Space!
