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
