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 1515: What Do Aussies Think About Space?
Wednesday Dec 27, 2023
Wednesday Dec 27, 2023
First off, apologies are in order for our extended absence from your podcast-hungry ears. We try our best to record on a consistent basis, but sometimes there’s a perfect storm of Life Events getting in the way for the Talking Space team when it comes down to getting an episode in the can. We DID even record an episode with Gene and Larry that we could not air because Larry’s audio track for the recording was not usable due to, of all things, an intermittently malfunctioning microphone. Sometimes the Universe just plain conspires against us.
In the News Roundup:
First: Be encouraged and inspired. Watch an interview with former astronaut Jose Hernandez on This Week in Space, as well as his new biopic, A Million Miles Away. Here’s a link to the trailer. His daughter interviews him here.
Next, we have an update on the Center for Biological Diversity, et al’s Starship lawsuit against the FAA, SpaceX, and a new defendant added recently: the U.S. Fish and Wildlife Service. Also, what’s happening now to qualify SpaceX for its IFT-3 launch license? We have all the latest.
Also, a final reminder: Send your name to Europa aboard the Europa Clipper spacecraft - check in at https://europa.nasa.gov/message-in-a-bottle/check-in/ or sign on at https://europa.nasa.gov/message-in-a-bottle/sign-on/ . The opportunity closes Dec. 31, 2023.
Finally: Want a picture of yourself on Mars? At JPL? In the Mars Rover Mission Control room? Check out the Mars Perseverance Photo Booth here.
Wrap-up and Impressions from ASCEND
As promised last time, Kat provides a wrap-up overview and her impressions from the ASCEND conference, including the probable extension of the commercial spaceflight regulatory “learning period” and news on lunar communications regulations.
What do Aussies Think About Space?
The Australian Centre for Space Governance (ACSG) has sponsored a study designed to measure Australian attitudes and opinions about space. We’re proud that Talking Space’s own Dr. Kat Robison Hasani helped design the study in her role as a Senior Research Fellow at ACSG. She brings us up to speed on the survey’s findings.
SpaceX 2023 Launch Count as of December 19, 2023: 92
SpaceX 2023 Projected Final Launch Count: 97 (almost made it to 100!)
More Website Woes
Yes, it’s true. Talking Space’s website – and email – are down again. And again, we’re “working the problem,” and will have things working again ASAP. The podcast itself has always been available wherever else you get your podcasts, as you know if you’re reading this.
Please be sure to let us know your thoughts on the topics we discuss. You can always reach us at mailbag@TalkingSpaceOnline.com.

Episode 1406: Launchapalooza
Sunday Aug 21, 2022
Sunday Aug 21, 2022
August 4th, 2022, was one of the most active launch days in recent memory. The Talking Space Team attempts to check all the boxes bringing a little insight into each one, including some launch audio from the Mighty AtalsV that carried the SIBRSGEO 6 into orbit and the scream of the Falcon 9 as it took South Korea’s KPLO probe to the Moon.
We briefly discuss some debris left from a Chinese rocket that showered down on the Philippines and some flotsam from the SpaceX Crew-1 Trunk that impacted an Australian sheep paddock.
The war in Ukraine has impacted everything for the worse. The repercussions have been felt far and wide, and the space sector has not been immune. The Northrup Grumman Antares 230 launch vehicle is another victim of the war; the fabrication shop for its core stage located in Ukraine was destroyed. With only enough parts to assemble two more rockets, Northrup Grumman has a plan for a domestic version of Antares, which will take an unusual alliance of a bold new corporate venture and an old lion ready to learn new tricks.
Speaking of Russia, is Roscosmos leaving the International Space Station Partnership like the mainstream media is saying? We provide real context around the story.
Artemis -1, the first launch of a new program to return humans to the Moon, create a sustainable presence there, and move on to Mars, is set for an August 29th launch attempt. We discuss the mission objectives for this first flight, the non-human crew, and the implications for this test flight.
Dr. Kat Robeson brings a NASA JPL article to our attention concerning the Antarctic Ice Shelf and the loss of mass it may have experienced. We also mention that on the day we recorded ( August 11th ), operational control of the Landsat 9 Earth Observation Satellite was turned over to the US Geological Survey from NASA. We end the show reminding all that while exploring the heavens is a vital part of space, looking down at our planet is just as critical.

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?

Episode 1207: Farewell 2020
Tuesday Feb 23, 2021
Tuesday Feb 23, 2021
Better late than never, so here's an episode full of launch and landing audio!
We begin with the launches Talking Space was fortunate to be at, including the first launch of the upgraded SpaceX Cargo Dragon, the much delayed Delta IV Heavy carrying NROL-44, and a launch and Return to Launch Site (RTLS) landing of a Falcon 9 booster from NROL-108.
We also discuss the recent launch and landing attempt for SpaceX's Starhopper SN-8 mission, and why ending in an explosion isn't necessarily a bad thing. They're not the only ones doing tests. Virgin Galactic is as well, and we've got the latest on their tests to get back into flight.
Finally we take a look at the NASA Authorization Bill, which looks at where the money will go for NASA's budget...and it definitely leaves a little to be desired...or does it? Listen to find out all the details.

Episode 1206: All For One, Crew-1 For All
Saturday Dec 05, 2020
Saturday Dec 05, 2020
From the Earth to the Space Station to the Moon, Talking Space is proud to be a part of history!
On this episode of Talking Space, we discuss the successful launch of the Crew-1 mission, sending four astronauts to the International Space Station.
We discuss all of the major historical achievements made during this mission. We also discuss what the atmosphere is like at the press site for a crew launch, in particular during a pandemic, and if the fan fare and unique feeling of a crew launch still exist.
We also end up discussion fashion and whether the public was really interested in this launch.
Next we discuss Rocket Lab's foray into reusability, and discuss the one thing we wish we knew to determine if reusability, especially from a company like SpaceX, is feasible.
We also discuss China's successful landing on the moon and the scientific and cultural significance of this mission.
Finally we say farewell to the Arecibo Radio Telescope, which has collapsed since this was recorded. We look into the main factors that led to the crash, since we believe it wasn't just storms or wear-and-tear behind the damage.

Episode 1205: "Scrubtember" Leads to "Grabtober"
Monday Nov 02, 2020
Monday Nov 02, 2020
On this episode of Talking Space, we go from the high-highs of space exploration to the low-lows of launch scrubs.
We begin with the announcement of water being found on the light side of the moon. We talk about the unique way it was actually discovered...and what we need to know before we can mine it and use it during future missions.
Then it's onto the continuing story of OSIRIS-REx, which successfully captured its sample from asteroid Bennu. We'll look at the unexpected issue it encountered and why every sample won't be studied when it returns to earth.
Then it's a review of "Scrubtember" and "Scrubtober" which saw an entire month without a U.S. launch, and Talking Space was there for many of them. Hear what it's like to scrub with an engine fire...then scrub again...then scrub another time as the press grows anxious and frustrated, and what it took to finally break the bad luck streak.
Next new crewmembers are now aboard the ISS, including the historic way they got to the station...and why the next crew will also make history.
After that, do you know how many different groups or organizations need to get clearance before a rocket can launch from the U.S.? Mark Ratterman takes us inside licensing for rocket launches and landings.
Finally, we go in-depth into the Artemis Accords, the follow-up to the Outer Space Treaty, and the one article in particular that could cause problems as private companies begin mining the moon, Mars, and asteroids.
