Episode 1607: Staying Healthy in Space: Unpacking the GEARS Experiment
Monday May 06, 2024
Monday May 06, 2024
In this special episode of Talking Space, we delve into a rarely discussed, but crucial aspect of living in space: health and sickness. We're putting the spotlight on the unique challenges posed by bacterial and viral infections aboard the International Space Station (ISS) and future long-duration missions.
We're bringing you a deep dive into a groundbreaking experiment, GEARS (Genomic Enumeration of Antibiotic Resistance in Space), recently transported to the ISS. What is the aim of this experiment? How can analyzing the genetic makeup of antibiotic-resistant microbes in space help us on Earth?
Joining us for this insightful conversation are Dr. Sarah Wallace, a NASA microbiologist at the Johnson Space Center’s Biomedical research and Environmental Sciences Division Microbiology Laboratory, and Dr. Christopher Carr, co-director of the Georgia Tech Astrobiology Program. They'll shed light on the history of sickness on the ISS, the precautions in place, and the worst-case scenarios of illness or injury that have occurred.
How do astronauts maintain personal hygiene in space? What kind of medical supplies are available aboard the ISS? Tune in to find out.
We're also discussing the specifics of the GEARS experiment. What unique insights can we glean from the genetic makeup of bacteria in space? How will this knowledge shape the future of long-duration space missions?
With the advent of commercial LEO destinations, how is the space industry preparing for microbial challenges? What discussions are under way to make new stations more resistant to accumulating microbes?
Lastly, we tackle the ultimate Doomsday medical scenario: What would happen in case of a serious illness outbreak on the ISS or during a long-term flight to Mars? We'll discuss how scientists are trying to mitigate the potential dangers of bringing Earth germs to another planet and the risks of bringing something dangerous back to Earth.
Don't miss this episode of Talking Space as we navigate the intriguing world of health and sickness in space.

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.
All this and more, on this episode of Talking Space!

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 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 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.
