Talking Space

This episode is packed full of news and insights. Let’s get to it!

In the News Roundup:

NASA selects the second lunar lander partnership for the Artemis moon missions
Rocket Lab scoops up a bargain with purchase of lease for Virgin Orbit’s Long Beach, CA headquarters and the usual “certain other assets”
Virgin Galactic’s Unity 25 successful test flight with a full test-crew complement – next comes paying customers
Spain joins the Artemis Accords
The Axiom Ax2 Mission is accomplished , spending eight days aboard the ISS and returning to Earth safely on May 30, 2023
Join the Europa Clipper mission and have your name engraved on NASA’s spacecraft as it prepares to leave for Europa

Next, Larry brings us a story about Elon Musk’s companies (SpaceX and The Boring Company) making messes seemingly everywhere they go in Texas . Regulatory agencies can hardly keep up with the citations and Notices of Violation for environmental and public safety concerns. Regarding our coverage of an environmentalist group’s lawsuit against the FAA: while we did report that SpaceX also responded to the lawsuit with its own filing with the court a request to be included as a defendant in the lawsuit, we did not mention in the episode that SpaceX’s filing outlines the potential consequences for the company if the environmentalists prevail in the lawsuit. These consequences include negative outcomes for its business as well as damage to the “substantial national interest.” SpaceX also asserted that the scientific knowledge facilitated by Starship would suffer as a result. These are all valid concerns, and it’s likely there are ways to satisfy both sides of this issue without undue delay or unjustified expense. We’ll be following this issue closely.

Finally, Gene and Sawyer provide detailed insights to the news that the first-ever crewed launch of the Boeing Starliner astronaut capsule has been delayed once again due to safety issues with the spacecraft’s parachutes and electrical wiring harness tape that were discovered in late May.

Talk about risky! This time around, the two cousins are being left alone to see what mischief they can get up to. Good thing there’ll be an adult in the room.

Mark Ratterman and Larry Herrin are joined by our guest, NASA’s Dr. Mary K. Kaiser, to discuss the omnipresent issue of space debris. We are “flexing” once again from our usual format to bring you a wide-ranging discussion that will cover how scientists objectively calculate risk versus subjective risk perception; dealing with Low-Probability/High-Consequence Risks; and the realities of basic human nature. How does all this relate to the issue of space debris and the world’s willingness to do something about it? We’re about to find out!

As mentioned, our guest for this discussion is Dr. Mary K. Kaiser. Dr. Kaiser spent 30 years as a research psychologist in the Human Systems Integration Division at NASA Ames Research Center. She now serves as a consultant to the Human Factors Technical Discipline Team at the NASA Engineering and Safety Center (NESC). This fascinating scientist spends her days worrying about things as diverse as subjective risk perception and innovative spacecraft instrument display technologies. She has authored or co-authored dozens of scientific papers, holds two patents, and is the self-published author of a novel, “The Muse of Kill Devil Hills,” available now on Amazon .
Then, see and hear Dr. Kaiser’s NASA NESC Academy presentation on “Miserable Risk Estimation: "Managing" Low-Probability, High-Consequence Risks" here.

If you want to hear even more about Dr. Kaiser’s very interesting career, keep listening after the main podcast for a big Easter egg’s worth of conversation we left there for you!

Gene Mikulka, Sawyer Rosenstein and Dr. Kat Robison will be back.

In this installment, we welcome Larry Herrin, a former 10-year-old Apollo astronaut, as the newest pundit on the Talking Space podcasting team. We forgot to mention in the show that Larry is also Mark Ratterman’s cousin!

As his inaugural contribution, Larry tells us about a relatively new, reusable, rocket-powered spaceplane designed and built by New Zealand-based Dawn Aerospace. You can find out more at Dawn Aerospace’s website .

Then Gene, Mark, and Larry take on the story of the week: The first launch of the SpaceX Starship on the morning of April 20. The team discusses the launch itself, the ramifications of the launch (citing “The Next 30 Trips ” blog and the" ESG Hound " blog ), the fallout from residents , the mishap investigation which has grounded the Starship program, and what may happen in the months ahead.

NOTE: Since this recording, several conservation groups have brought legal action against the Federal Aviation Administration (FAA) for granting the Starship launch license to SpaceX. This will be a story we will be following.

Sawyer Rosenstein and Dr. Kat Robison will be back.

We start this week off with a roundup of news from NASA with the announcement of the Artemis II crew , its Mars Habitat , the second independent review of the Mars Sample Return , and a celebration of two missions hitting 50 - 50 orbits for Juno and 50 flights for Ingenuity (and you can even an audio recording of the Mars helicopter here ). We then chatted about Blue Origin’s Club for Future and the FAA licensing of Starship’s launch attempt.

The first of our main stories was a discussion of the successful launch of ESA’s JUICE mission to study the icy moons of the Jovian system, including taking some selfies as it began its journey. We wrapped up with a report from the recent NASA student launch competitions, which you can see for yourself on MSFC’s YouTube .

Talking Space returns for its fifteenth season with a new format!

First up, we have a brief roundup of news, including Kathy Lueders retirement from NASA, with Ken Bowsersox set to take over Space Operations on May 1st, the cessation of Virgin Orbit’s operations, more delays with Starliner, Soyuz’s uncrewed return to Earth, and a special report on one of our favorite non-rocket vehicles at KSC from Mark.

We then head down under as Kat provides an update on Australian space news, including AUKUS in space, NASA’s visit to Canberra and Adelaide, including their announcement of a new Indigenous internship at JPL, and the first woman to be trained under the Australia Flag, Katherine Bennell-Pegg – who also happens to be the Director of Space Technology at the Australian Space Agency. Mark continues our show with a discussion of the next Artemis RS-25 , and shares some facts about the engines from Aerojet Rocketdyne that were even new to us on the show.

Gene rounds the show off with a discussion of the complicated funding and politics of the VERITAS mission to Venus, which has encountered delays and setbacks (and what amounts to a “soft cancellation ”), despite being on budget and time and the exciting announcement of volcanic activity on Venus.

We dedicate this show to the memory of Helene Smith . Please be sure to let us know what you think of the new format and let us know your thoughts on the topics of the show.

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.

On this episode of Talking Space with Mark Ratterman and Dr Kat Robison we have an excellent interview from Mark with Kennedy Space Center’s Dr Kristin Smith and Kathy Rice, both of whom are in KSC's weather office. Special thanks to KSC’s public affairs team, especially Mary MacLaughlin, who make it possible to bring interviews like this to our listeners. Mark talks with Kristin and Kathy about NASA’s Tropospheric Doppler Radar Wind Profiler (TDRWP) which monitors weather in the upper atmosphere like upper level winds (which we all know are very important on launch days). Kathy and Kristin explain how users, from NASA to SpaceX, utilize this important data and how it differs from other tools, such as weather balloons. The data from TDRWP is publicly available . Also, check out this link for info on how it was tested with ham radio operators and this site for more info on the whole system at KSC.

Mark and Kat also have a brief chat (and please forgive her technical difficulties!) about a few space news topics before the interview. Kat shares about a history making series of launches in Australia at the Arnhem Space Centre (ASC) in the Northern Territory. The series of three sounding rocket launches to study astrophysics were the first NASA launches from a fully commercial spaceport and were undertaken in partnership with Equatorial Launch Australia . She and Mark also discuss the first deep field image from JWST, which includes light from one galaxy which traveled 13.1 billion years to JWST’s mirrors. Find out more and see the rest of JWST’s first images here .

This episode we take a unique look at the historic Axiom-1 mission to the ISS from multiple perspectives.

That includes our own Sawyer Rosenstein who was at the press site for the launch and our own Mark Ratterman who viewed the launch from offsite. There was a unique oddity to the audio from this launch which you'll have to hear for yourself.

We compare how this mission differs from other SpaceX missions to the ISS, typically carrying astronauts for NASA and ESA, including some pre-launch quirks. Plus, what a private mission like this does to scheduling aboard the International Space Station, especially as a long-duration crew depart and return within weeks of this all-private mission.

Plus, this isn't just a tourist mission. We look at the experiments being done onboard this first all-private mission to the orbiting laboratory.

In addition we also take a look at the ongoing effects of Russia's war with Ukraine on relations aboard the ISS.

Finally it's a look at the Artemis program's latest concerns and announcements. That includes the roll back of the massive SLS rocket set to launch the first uncrewed test mission around the moon sometime this year after some issues appeared during a "wet dress rehearsal". Also a look at what vehicles will likely be taking astronauts to the launch pad before they depart for the moon.

Our Mark Ratterman was on hand at NASA's Kennedy Space Center for the rollout of America's new launch vehicle: NASA's Space Launch System (SLS) rocket with the Orion Spacecraft sitting atop the 322 foot stack. . It was the first time a large rocket set on its way to the launch pad from the Vehicle Assembly Building since the Space Shuttle. No longer on the drawing board or an artistic rendering, Mark was on hand to bring us his unique perspective on this moment of history, including a reminder that space travel isn't just technology, there's a very human side to it too.

The team discussed the upcoming preparations for the initial Wet Dress Rehearsal, a test of the rocket's ground support equipment, procedures, and the people who will be responsible for launching the SLS/Orion combination on the first leg of the journey to the Moon.

The team also examines further the impact of Russia's actions in Ukraine and the continued fallout there has been for the spaceflight community, and we end with a light side of space courtesy of the Canadian Space Agency.

The concept that space unites nations on Earth is tested like never before.

In a rare single topic installment of Talking Space, the team pauses its regular reports and observations of the space sphere and examines the impact of the current geopolitical circumstances and the short and long-term impact they may have on space exploration going forward.

Recorded on the evening of Saturday, March 5th, 2022, we look at the implications the Russian-Ukraine conflict will have on the International Space Station and its logistics chain, both transporting crew, and cargo. Also, what impacts are there to various other launch service providers, many of whom are already in a state of transition with their booster programs, and who may be most vulnerable to the situation?

Another area we place under our microscope: the status of the Russian space program going into this crisis, the damage caused by the conflict plus some wounds that the agency may have inflicted upon itself since the start of hostilities. We attempt to take on the big question of what the future hold for Roscosmos, the ISS partnership, and future cooperative efforts.

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!

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.

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.

This episode takes us all over the world from the U.S. to Russia, from public to private. It's a global and low earth orbit episode of Talking Space.

Has Russia's Roscosmos become a little more "Space-X" like in their launch coverage to the point where they have started to rival NASA's? The team looks at the possibility.

The orbiting homestead called the International Space Station underwent some renovations, installing a set of a new set of ISS Roll Up Solar Arrays or iROSA's. These not only will this power up the station for the next set of demands the platform will face in the coming years but the roll-up arrays are also a technical demonstration for NASA's upcoming Artemis Lunar Program.

NASA's Space Launch System core stage is in the Vehicle Assembly Building at the Kennedy Space Center in Florida and is being stacked for a launch attempt. This is just one more step for the first Artemis mission. The team discusses the SLS as a scientific exploration tool, to allow planetary spacecraft to reach destinations faster, so they can begin data collection and return expeditiously.

China has launched the first segment of its Tiangong space station and the crew has arrived to live on the platform for 90 days. It shows that China is indeed pursuing its own agenda in space but will it produce the same level of science that the International Space Station has and will it be as friendly to work with?

Blue Origin's Jeff Bezos announced that he is flying on the inaugural "New Shepard" sub-orbital flight for paying clients on 20 July. A few days later Richard Branson then announced that he intended to fly on Virgin Galactic's first commercial sub-orbital mission before Bezos. Does this sub-orbital one-upmanship signal the start of a new era, opening spaceflight for all, or is it just a case of two large egos? The team looks at the promise that both these spacecraft have as scientific and research platforms.

The era of US crew transitions onboard the International Space Station has resumed with the launch of the Crew 2 mission to the orbiting facility and the return of the Crew 1 astronauts via the Commercial Crew Space X Crew Dragon Capsule. The flight is also is a moment of history in both the United States, Europe, and Japan in their space program as well, and the team brings all into perspective. Also, Sawyer Rosenstein was on hand for the Crew-2 Launch and collected some great sounds of the SpaceX Falcon 9 as it reaches for the Space Station with its multinational crew on board.

China places the first segment of its space station to orbit, but it's not without consequences to those back on Earth. The core stage of the Long March 5B booster was not equipped to be disposed of properly while on orbit. We explore some of the implications of this with our own Dr. Kat Robison.

A new NASA Administrator has been installed, and it's someone who is no stranger to US space policy and politics. Former Senator Bill Nelson has been sworn in as NASA's 14th Administrator, and the team has no shortage of observations and opinions to share on how the new Administrator's tenure may unfold.

The Human Landing System decision was handed down in recent weeks, but the single provider decision is not without controversy. We debate the wisdom of the decision and why the two other providers under consideration have filed protests.

To close the show for this week, we make the passing of a true gentleman who has forever made a mark in human space history. NASA Astronaut Michael Collins passed away at the age of 90 after a battle with cancer. The team celebrates his life and his accomplishments.

All that and more on this installment of Talking Space.

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.

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?

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.

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.
