Episode 1609: Double Stars Rising
Monday Jun 17, 2024
Monday Jun 17, 2024
After years of development, testing, disappointment, and perseverance, NASA astronauts Butch Wilmore and Suni Willams took Boeing's CST 100 Starliner to the International Space Station for its first flight with a human crew. The team discusses all facets of the launch, rendezvous, docking (not without its moments of drama), and public reaction to the mission thus far.
Also this week, the fourth test flight of the SpaceX Starship Super-Heavy booster and a re-entry test of the Starship vehicle itself. The super-heavy vehicle is critical for NASA's Artemis lunar landing program, and a derivative of Starship was selected by NASA to be the human lunar lander used on Artemis III. The team puts the fourth Starship test into perspective.
Starship development was also critical for the SpaceX/ Yusaku Maezawa dearMoon program, which was to take Maezawa and eight invitees into orbit around the Moon. However, Maezawa announced that since a 2023 launch had become "unfeasible" and lacked a "clear schedule," he was canceling the program. The announcement drew some ire in the space community, and we examine the fallout.
One of The Hubble Space Telescope's three gyroscopes used to point the telescope to distant objects has failed. We look at a Media Telecon where NASA's astrophysics leader, Dr. Mark Clampen, indicated the agency will continue to utilize Hubble in a "one gyro mode" so the iconic telescope can still deliver good science with only a 20% loss of capability. The orbiting telescope is in overall good health and should continue to operate until 2035. At the same teleconference, Dr. Clampen announced that NASA has no intention of launching a Hubble servicing or re-boost mission in the foreseeable future. This news ends the SpaceX/Polaris plan to launch a possible servicing mission to the telescope. A May 2024 NPR article by Nell GreenfeldBoyce also reported NASA's concerns about the unsolicited proposal.
Sadly, the past few episodes have ended in obituaries, and that trend continues. The team takes a few moments to remember NASA Apollo 8 Astronaut William Anders, who died in a plane crash this past weekend.
All this and more in this edition of Talking Space!
UPDATE ONE: During the show, we reported that the new undock date for Starliner was on 22 June. After we published, NASA and Boeing decided to do some more analysis on the thruster issues experienced during last week's docking to the ISS. To understand the Starliner Service Module more, ( the service module does not return ) NASA and Boeing have now indicated that Starliner will undock from the ISS at 10:10 PM EDT on Tuesday, June 25th with a landing planned at the White Sands Space Harbor in New Mexico at 4:51 AM EDT on June 26th.
UPDATE TWO: In A Blog Post Today (21 June 2024) NASA and Boeing Space announced that they are waiving the return date of 26 June for Starliner, with a new date to be announced at a later time. To quote the NASA blog post: " The move off Wednesday, June 26, deconflicts Starliner’s undocking and landing from a series of planned International Space Station spacewalks while allowing mission teams time to review propulsion system data."
Steve Stitich, NASA's Commercial Crew Program manager said “We are strategically using the extra time to clear a path for some critical station activities while completing readiness for Butch and Suni’s return on Starliner and gaining valuable insight into the system upgrades we will want to make for post-certification missions.”
NASA Reports that Starliner remains healthy and that CFT Crew Members Butch Wilmore and Suni Williams continue to support the Expedition 71 Crew with their activities on the International Space Station.
Talking Space will continue to follow the story as it develops.

Episode 1605: Getting the NAC of Things
Monday Apr 08, 2024
Monday Apr 08, 2024
Is the NASA Advisory Council (NAC) system becoming unglued? During the NAC Science Committee meeting on March 21st, there were significant questions about the Primary NAC and its ability to deliver recommendations to NASA's leadership expeditiously so they can be acted upon by NASA Leadership. That wasn't the only thing on the minds of NASA's scientists and advisors. The Hubble Space Telescope and the Chandra X-Ray Observatory are profoundly impacted by NASA's austere FY 24 and FY 25 budget constraints, and one of the two missions may face cancellation. Also, the significant demands placed on NASA's Deep Space Network were of major concern. We report on what was said and offer analysis.
The Intuitive Machines IM-1 mission was officially declared completed when, as predicted, the robotic Odysseus lunar lander did not respond to a "wake-up" call on March 23rd. Larry Herrin and Mark Ratterman talked with Chantelle Baier, CEO of 4Space, who facilitated one of the commercial payloads on the IM-1 mission, to wrap up her experiences on the flight and discuss future endeavors. See Jeff Koons Moon Phases web site to explore the details of his art, exploring themes of connectivity and acceptance.
NASA extended its call for new astronaut applications through April 16th and Mark Ratterman highlights what the US Army is doing to encourage applicants in its ranks.
After the joint Boeing Space/NASA press conferences last week highlighting the upcoming first crewed flight test of the CST 100 Starliner, some words were put out on social media by some prominent individuals in space advocacy berating Boeing Space. In a commentary, Gene Mikulka poses a question: Can't we wish Butch Wilmore and Sunni Williams well and forget about wearing our corporate t-shirts for a little while?
Finally, Space exploration lost two giants this past week, and we look back on the lives and contributions of former astronaut General Thomas P. Stafford and former Johnson Spaceflight Center Director George W.S. Abbey.

Episode 1512: Pretty Plasma Trail, But Not from Starship Anytime Soon?
Sunday Sep 17, 2023
Sunday Sep 17, 2023
This episode brings lots of Space news from around the globe, as well as from our own back yards. Literally.
First off: both Sawyer and Mark witnessed the plasma trail from the latest Crew Dragon reentry from their own back yards. A photo that looks … kind of like what they saw (taken by NASA) … is shown here.
Next, we have plenty of news in the roundup, including:
- How LeoLabs worked with the European Space Agency (ESA) to support Aeolus satellite’s controlled reentry
- ULA's 98th launch for NRO and 157th launch with 100 percent mission success was SILENTBARKER/ NROL 107 on 10 Sept, 2023
- How and why the majority of NASA’s buildings are in need of serious maintenance – or demolition
- The ongoing New Horizons Mission saga
- Virgin Galactic flies a group of “Founder” astronauts in its fourth flight
- NASA’s Frank Rubio breaks the US space endurance record
- NASA and Axiom announce the Axiom 3 crew
- The GAO says NASA’s Space Launch System needs more cost transparency
Then, the team discusses the 36-page report of the NASA Unidentified Anomalous Phenomena (UAP) Independent Study Team. NASA formed this external, 16-member independent study team of experts in July 2022 to find a way we can use our open-source data and resources to help shed light on the nature of future UAP. The report is a summary of the proposed ways NASA can do that using mostly existing resources, as well as new, inexpensive crowdsourced methods to collect future UAP data in a scientifically rigorous manner. You can find a copy of the report here.
Finally, we can’t let an episode go by without an update to the goings-on in the world of SpaceX and Starship:
- First, no new developments as of our recording date were publicly documented since July 26, 2023 in the lawsuit brought by the Center for Biological Diversity, et al against the FAA and SpaceX.
- On September 10, 2023, an apparently redacted/rephrased list of 63 corrective actions was published by Elon Musk on X. None of these addressed the requirements of the Clean Water Act in terms of procuring an Industrial Wastewater Permit for the new deluge system.
- On September 13, 2023, acting FAA Administrator Polly Trottenberg told reporters on the sidelines of a conference that “We’re working well with them (SpaceX) and I think we’re optimistic sometime next month,” whatever that means.
- Trottenberg also mentioned that SpaceX would also need a separate environmental approval from the U.S. Fish and Wildlife Service before a launch. She didn’t say how long that might take.
- Late Friday afternoon on September 15, 2023, the day after this show was recorded, came news via emailed news release that the FAA was performing a Written Reevaluation (WR) of the 2022 Programmatic Environmental Assessment (PEA). The WR will evaluate all the new environmental data collected as a result of the April 20, 2023 initial test launch of Starship, and an Endangered Species Act consultation with the U.S. Fish and Wildlife Service. This news could have a huge and potentially devastating effect on the timeline for the Flight 2 Starship launch. More details can be found here. We’ll keep you informed as events unfold.

Episode 1509: Starship Launch Delays – a Triple Whammy?
Sunday Jul 30, 2023
Sunday Jul 30, 2023
SpaceX’s effort to launch its second integrated test of Starship is likely facing a triple whammy of delays, including a new one that should really be of no surprise to the company. It certainly is no surprise to Eric Roesch, who joins us on this episode to discuss the latest developments in the saga.
First, there’s the well-known environmental lawsuit brought by a consortium of environmental and tribal groups against the FAA and SpaceX. This case showed a little movement on July 25, 2023, and all the details on what did transpire in court filings on that date can be found here.
Turns out that the latest filing in the case (as of this writing) would extend the deadline for proposing a briefing schedule as to summary judgment within 14 days of the Court’s resolution of Plaintiffs’ motion challenging the Administrative Record, if any is filed. And that resolution could come as late as December 2023 or January of 2024, or maybe even later. And all of this time may be used up just to get to the point where all sides agree on what the tools look like that they’re going to use to prosecute the case.
Second, the FAA just reminded everyone on July 26th that SpaceX has not yet submitted a Mishap Investigation Report for its review. This report would outline what SpaceX needs to do to demonstrate to FAA that Starship is safe enough for another launch attempt.
And the third element of the triple whammy? The new water deluge system freshly installed and tested beneath the Orbital Launch Mount (OLM) has no Industrial Wastewater Permit to go with it. Eric gives us a full rundown of all the wonky stuff, as well as the inside scoop as to how long a delay this could cause (spoiler alert: it’s a long time!). And not only has SpaceX not applied for the permit yet, but according to Eric, SpaceX knew they had to do it way back when they wrote the latest Programmatic Environmental Assessment (PEA) that governs the whole environmental shooting match. Is there something that SpaceX knows that we don’t, which will let them circumvent the Clean Water Act? How will SpaceX pull this off?

Episode 1507: A Secret Mission and … OceanGate’s Titan?
Friday Jul 14, 2023
Friday Jul 14, 2023
You may ask, “Why are we talking about the OceanGate Expeditions’ Titan submersible tragedy in a podcast dedicated to space-related stuff?” The commonality with undersea exploration is the lack of Human Commercial Spaceflight Safety Regulations. Do we need more regulation? The team muses about this issue in this episode of Talking Space.
But first, the News Roundup:
- Mark manages to both provide us interesting info as well as to humanize the launch he witnessed of a classified military payload -- the mission designated NROL-68.
- A classified military orbital mission notwithstanding, there’s still lots of news we CAN provide details about in this episode, including the ribbon-cutting ceremony for NASA’s Earth Resource Information Center in Washington, D.C.
- The final flight of the Ariane V, VA261, was postponed during rollout. After an additional weather delay on July 4, the final launch of the Ariane 5 rocket took place on Wednesday, July 5.
- Ecuador and India become the 26th and 27th signatories of the Artemis Accords.
- The Mars Sample Return mission’s cost has skyrocketed, according to a report in Ars Technica. Will it affect the budgets or existence of other planetary research missions? Gene has some insights.
- The Deep Space Food Challenge, an international competition sponsored by NASA to innovate food production for deep space missions, is heading into its final phase. Mark has details.

Episode 1401: Rockets and Future Visions
Sunday Feb 27, 2022
Sunday Feb 27, 2022
On a very SpaceX-centric edition of Talking Space to start 2022, The team looks at the SpaceX Polaris Program that hopes to test elements needed for operating the SpaceX Starship, including the first Extra-Vehicular Activity or Spacewalk for a private space mission.
We take a look at the SpaceX Starship update event held at the SpaceX Boca Chica, Texas, on February 11th, which was heavy on theater but light on news. There are also questions on the future status of the SpaceX Boca Chica location (AKA “Starbase”) due to environmental concerns, and the FAA has pushed back the decision on certifying the location for launching orbital flight missions due to the number of petitions filed. We explore the reasons for the controversy.
There has been a delay in the rollout of the Space Launch System rocket for the Artemis 1 mission, and we explore the reasons for the delay.
We wrap up with some good news on the International Space Station mission receiving an extension into the year 2030 and the progress being made on the commissioning of the James Webb Space Telescope.
All this on this first edition of Talking Space for 2022!

Episode 1306: Zero-G and I Feel Fine - Mission: Astro Access
Monday Nov 15, 2021
Monday Nov 15, 2021
On this very special episode of Talking Space, we discuss something very few people have ever experienced, Zero Gravity. However, 12 Zero-G flyers just made history.
12 ambassadors for "Mission: Astro Access" completed the first ever microgravity flight for people with disabilities. That includes people who are deaf/hard of hearing, blind/low vision, and have mobility disabilities. Among the flyers is our own host, Sawyer Rosenstein. He invited some of the participants onto the show to discuss the mission.
The flight itself involves 15 parabolas aboard a Zero Gravity Corporation plane with one Martian, two Lunar and 12 "Zero-G" parabolas.
That includes the selection process, the training before flight, and the objectives during the flight. We find out what worked, what didn't, and the simple modifications that can be made to make spaceflight accessible to so many more people. We also discuss the future, where we hope this program goes in the future, and the changes we all hope to see as a result of this historic first mission.

Episode 1305: Space is Open for Business
Wednesday Oct 06, 2021
Wednesday Oct 06, 2021
If it seemed like average people flying into space was something from the future, this episode is proof that the future is now...or is it?
In this episode of Talking Space, we start with the launch of the first all-civilian orbital mission, Inspiration 4. We report what it was like from the grounds of the press site (including some fantastic Falcon 9 launch audio) and the reception it received from the public. However it's not all cheers to a new era of spaceflight as some of our team members and the public say space isn't for everyone just yet.
We also discuss the upcoming private Axios mission to the International Space Station getting a launch date, and how the launch of a Russian actress is delaying important work to the newly-installed Nauka modules, which has had some issues from the moment it arrived at the station.
We then dive into the delays for the Human Landing System because of a lawsuit. The question remains, even without the lawsuit, is 2024 still viable to land on the moon?
We then also discuss the reorganization of NASA's Human Exploration and Operations Mission Directorate. It left a lot of questions about what that means for the agency, especially this far along with Artemis, which we hope to answer.
Finally, we've heard about unruly passengers on commercial flights, but our FAA expert Mark Ratterman looks into what might happen if you get an unruly passenger on a spaceflight.

Episode 1302: Turn it Up to SN-11
Monday Apr 12, 2021
Monday Apr 12, 2021
This episode is full of plenty of rockets and missions going up....and one that went down explosively.
On this episode, we begin with two crew launches. First the Soyuz MS-18 mission and why an American astronaut was added only a few months before launch. Plus a quick look ahead to Crew-2 aboard a Crew Dragon, and a possible new tradition started by the crew.
Next it's on to Mars, where the Ingenuity helicopter is set to take off. This isn't just significant for future Mars exploration. We go into the potential historical impact of a mini helicopter flying on another world.
Then it's onto the nominee for NASA's next administrator, former Senator Bill Nelson (D) Florida. Former administrator Jim Bridenstine thinks it's a good pick, but what does the panel think?
Then it's onto SpaceX. First, the farewell to Ms. Tree and Ms. Chief, the fairing recovery ships. What does this mean for reusability.
Last but no least, it's all about SN-11, the Starship test flight from Boca Chica (or Starbase depending on your preference) Texas. The mission went up under heavy fog before exploding before landing. What does this mean for the program? Can you still get enough data from just telemetry as opposed to visuals? What led to the decision to fly on that day and how is the FAA somehow involved? Also, is SpaceX learning from these test flights or is it just for show? We look at all these questions and more.

Episode 1301: Three Cheers for Mars
Tuesday Mar 23, 2021
Tuesday Mar 23, 2021
One week, three crafts, one planet. On this first episode of Season 13 we're aiming for Mars.
We discuss three successful missions arriving at the red planet within one week of each other, the "Hope" mission from the United Arab Emirates, China's Tianwen-1 Mission, and the most discussed mission of the three, NASA's Perseverance Rover. We go into all of the amazing firsts so far, and what the mission should accomplish during its time on the red planet. Also, find out why Mark doesn't like calling the rover "Percy".
Next, we discuss the future for RocketLab, including their CEO literally eating their hat as they announce the design of a new rocket.
Finally we discuss the Inspiration 4 mission, which will send ordinary people to space along with helping a good cause...but is it really giving anybody a chance to go, or is it favoring certain people more than others?
