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 1510: Artemis III – A Different Mission?
Sunday Aug 20, 2023
Sunday Aug 20, 2023
ESA’s Aeolus earth observation satellite, launched in August 2018, ended its primary mission on July 28, 2023. It still had one final mission: a safe, fiery, controlled reentry into Earth’s atmosphere conducted by the European Space Agency flight controllers. Larry Herrin provides details of the importance of this maneuver.
August 8, 2023 was Artemis II media day at NASA’s Kennedy Space Center. NASA Administrator Bill Nelson, Associate Administrator for Exploration Systems Development Jim Free, and the Crew of the Artemis II mission, provided an update on the upcoming lunar reconnaissance mission. Jim Free was also asked about the status of the Human Landing System and how its progress may impact the Artemis III lunar landing attempt. Gene Mikulka reports. The link to the press conference on the NASA YouTube page can be found here.
In a separate press telecon on August 7, Boeing Space and NASA gave updates on the progress of the Starliner capsule that will be used to transport crew to the international space station. Boeing’s Mark Nappi indicated that the capsule will be ready for the long-delayed Crewed Test Flight (CST) in March of 2024, pending the completion of remediation steps for the P-13 tape, which was found to be flammable and a required modification to the main reentry parachutes being made by partner company Airborne Systems.

So you’re a farmer seeking computer programs to help with drought or looking to track storms that might impact your crops? Perhaps you’re a researcher looking for modeling software or trying to figure out how to predict lightning strikes. As Mark Ratterman reports, NASA has an app for that! There are about more than 1,000 free programs and algorithms free for the taking at software.nasa.gov.
We provide an update on the SpaceX Boca Chica lawsuit and other developments that we’ve been following: CNBC’s Lora Kolodny reports that the company still has yet to apply for an Industrial Wastewater Permit but, according to the report, still went ahead with a full pressure test of the flame deflector for the Starship launch pad (and used it for the Booster 9 static test) despite not having the required permit for such a discharge. The team discusses these developments and will continue to watch and report. UPDATE: According to PayloadSpace.com on Tuesday, August 15, 2023, SpaceX submitted its long-awaited Mishap Investigation Report to the FAA for review.
So whatever became of the American flag planted on the Moon by Apollo 11? Larry Herrin discusses a PhysOrg article about the history of the last-minute scramble to include it in the mission, the fate of the artifact and what might be its current state.
And speaking of the Moon, once the astronauts of NASA’s Artemis program arrive on the lunar surface, they’ll need power systems for essential systems, transportation, and conducting experiments. Mark Ratterman explores two companies – Blue Origin and Zeno Power Systems – and describes their proposals to deliver energy to lunar explorers. Here is the Zeno Power Systems press release.

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 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 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 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 1003: Creepy Face in Space
Monday Mar 12, 2018
Monday Mar 12, 2018
50 Falcons, falling stations, private ISS, the dreaded NASA budget and a lot of hate mail...all in one episode!
On this episode of Talking Space, we begin with our launch round-up including GOES-S, the 50th Falcon 9 launch, and the return of three crewmembers from the ISS and the preparations for the next launch later this month. Then it's onto a creepy talking head that'll be soon heading to the ISS, as well as another space station, Tiangong-1, that could fall pretty much anywhere as professionals track it and amateurs buy umbrellas. Next it's the dreaded NASA budget review, including a meeting with NASA Acting Administrator Robert Lightfoot and congressional budget officials. In this is the discussion of potentially privatizing the ISS, getting NASA out of low earth orbit, and dealing with NASA's "leaning tower of KSC".
We finish up with the Areceibo Radio Telescope getting new owners, a chance to get your name on the Parker Solar Probe, and a much-needed clarification segment. In this segment, we discuss and clarify all of our points regarding Falcon Heavy after some heated feedback on our last episode. Also be sure to stay past the outro music for a fun surprise.

Episode 1002: Falcon Heavy Finally Flies
Monday Feb 19, 2018
Monday Feb 19, 2018
7 years...5 blocks...27 engines...2 booster landings...one spectacular Falcon Heavy launch. All that in this episode of Talking Space.
On this very special episode of Talking Space, we discuss the successful demonstration flight of SpaceX's Falcon Heavy rocket. The launch took off February 6th, 2018 at 3:45pm ET followed by the two side boosters landing a short time after. The core stage attempted to land on a barge but failed, and we'll explain why.
Our own Sawyer Rosenstein was there, so be ready to immerse yourself in the sounds of 27 engines firing at once, and be prepared to get startled by six simultaneous sonic booms.
In addition to that, we discuss our thoughts on the payload, Elon Musk's Tesla Roadster car with a dummy named "Starman" inside aimed for a mars orbital insertion distance without the insertion. You'll get our honest opinions on why some of us like the payload and others don't. In addition, Sawyer goes into everything that happened from L-1 until after the liftoff. Hear what it's like to go inside the pad, see more media at the press site than in at least 3 years if not more. You'll also hear both the good and bad of how the media was handled.
Lastly, we break down the numbers compared to other launch vehicles and see how powerful Heavy really is, and how those numbers led to a war of words on Twitter amongsome major private space companies.
In the show we discuss the comparison between its announcement and its launch. To hear our initial reactions from 2011 right after it was announced, check out a special blog post with a segment from our very own show back in Season 3 by visiting the blog page on our website or clicking here.

Episode 917: Houston, We Have a Special: Part 2
Monday Jan 08, 2018
Monday Jan 08, 2018
The final part of our exciting two-part special has us sitting in front of an Orion mock-up chatting with astronauts and project leads.
On this episode of Talking Space, we go into Building 9 at the Johnson Space Center in Houston, Texas. While there we talk with NASA astronaut Steve Bowen in front of a full-scale mock-up of the Orion capsule that astronauts like Steve use to train everyday. We talk about how the astronaut corps has changed since the end of shuttle. Plus, hear how he used the full-scale mock-ups in the building such as the full International Space Station, a space shuttle trainer, and more.
Next we hear from Jimmy Spivey, the Assistant Director for Orion in the Flight Operations Directorate at Johnson. We get an insight into the progress of the Orion program, how delays from ESA affect the training. We also go into what it takes to train the crew and to coordinate between mutliple NASA centers and countries. We also hear about how Orion and SLS integration is being tested. Most importantly, we hear what he has to say to the nay-sayers who think Orion and SLS will never fly.
We also discuss many of the other cool things in the building, including a full-scale BEAM module, s SARJ, and how Sawyer and Robin entered a fish bowl. All this in the final episode of Season 9. Later this motnh, stay tuned for the debut of Season 10!
Talking Space would like to thanks Brandi Dean and the team at NASA Johnson Space Center's Office of Communications for their assistance with both parts of this special.

Episode 915: Flying Through the Ashes
Sunday Dec 10, 2017
Sunday Dec 10, 2017
Our launch roundup turns into a lack-of-launch roundup and we actually break news for the first time in the show's history. All that and more on our penultimate Season 9 show.
We being this episode discussing the indefinite delay of the classified Zuma mission aboard a Falcon 9 rocket. We also discuss CRS-13, the first mission to fly from SLC-40 since a failure last year. That mission, flying a previously-flown booster and capsule, also delayed. To round out the SpaceX pushes, we discuss another delay in Falcon Heavy to sometime in 2018. We also talk about another Russian rocket failure and the dumb reason why it failed, that along with a look at their less than stellar 2017 record.
We then reflect on three years since EFT-1 and reminisce on the day and look towards the future. We then get an update on DreamChaser after their most recent drop test. Lastly, we venture out of the solar system as Voyager 1 tests out one of its systems for the first time in decades.
