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 1508: Starship, ULA & STEM news
Sunday Jul 23, 2023
Sunday Jul 23, 2023
The environmental lawsuit brought by a consortium of environmental and tribal groups against the FAA and SpaceX has shown no visible movement since July 5, 2023, but we have all the details on what did transpire on that date. Turns out that since our recording date, another filing in the case 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 in the timeframe of December 2023 or January of 2024, or maybe even later. More on this to come next time!
Believe it or not, there are a few other stories in the News Roundup:
- NASA selects Axiom Space and Collins Aerospace to further advance the capabilities of their respective spacesuits by pulling a switcheroo on them.
- A new robotic, scientific instrument package with a lovely new acronym – DIMPLE – has been selected for Artemis through NASA’s Commercial Lunar Payload Services (CLPS) to study volcanic terrain on the Moon.
- The asteroid sample-return mission known as OSIRIS Rex is making a number of course-correction burns this month to set it up for a precision landing in the Great Salt Lake Desert on September 24, 2023.
Next, the United Launch Alliance (ULA) says despite recent anomalies involving their Centaur V upper stage and the BE-4 engines built by Blue Origin, Vulcan should still fly this year, although behind schedule. We respectfully disagree.
Then, we bring you a discussion on a subject near and dear to everyone’s heart here on the Talking Space team: STEM education programs and their importance in securing the future competitiveness of the USA, the future of our children and the well-being of the planet. FYI, STEM represents science, technology, engineering and math. NASA has recently awarded millions in STEM research grants to schools all over the country. All this may sound corny, but you can’t argue with how it’s changed lives. Also, here’s a STEM center success story that is very personal to Sawyer.
Finally, a reminder from whence we came: This past week was the 54th anniversary of the Apollo 11 Moon mission, which carried Neil Armstrong and Buzz Aldrin to the lunar surface for the first-ever manned lunar landing on July 20, 1969. Meanwhile, Michael Collins piloted the Command Module, which then took all three astronauts back home.

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 1202: Suborbital, Orbital, and Interplanetary
Tuesday Jun 30, 2020
Tuesday Jun 30, 2020
The “band” is back together to review some breaking news on the launch date for NASA’s upcoming Mars 2020 Perseverance Rover. We talk about the activities on the International Space Station, where NASA Astronauts Chris Cassidy performed a 6-hour 7-minute spacewalk to replace a set of lithium-ion batteries on the facility’s S6 truss. Completing this work will leave the ISS in an exemplary power configuration for the remainder of its operational life.
Attention turns to a Pre-spacewalk briefing NASA’s Kenny Todd, and Steve Stich had good words on how well the SpaceX Crew Dragon is performing for its first-time on-orbit and information on when perhaps the Crew-1 mission could fly. Also included was a status on where Boeing was with remediation work on the CST-100 Starliner spacecraft.
There was an abrupt “changing of the guard” at NASA’s Human Exploration and Operations office. Kathy Lueders, the Director of the Commercial Crew Program, was promoted to Associate Administrator for the Human Operations and Exploration Directorate replacing Douglas Loverro. He resigned under a ‘dark cloud’ for what he called ‘a mistake’ in his final letter to the HEO organization. That “mistake” is now under the microscope of the NASA Inspector General’s office.
The NASA Headquarters Building in Washington DC has a new name; we tell you who it is and why that honor was bestowed, plus give you a little hint about another historical figure of note we’re going to discuss on a future show.
Our grand ‘pundit of podcasts’, Mark Ratterman has a NASA Podcast that you may wish to add to your diet of space news and information: NASA Johnson’s “Houston We Have a Podcast.”
Want all of the Earth Observation satellite data that NASA, Europe and Japan have gathered about how the COVID 19 pandemic has impacted socioeconomic activity all in one place? There’s now an appfor that! Introduced by all three space agencieson June 24th2020, it aggregates all of the data tracking air and water quality plus agricultural and economic activity all in one place.

Episode 1107: The Path to #LaunchAmerica - Demo-1
Tuesday May 26, 2020
Tuesday May 26, 2020
With astronauts set to return to space from U.S. soil for the first time in almost nine years, Talking Space is going back through the archives to bring you never-before-heard episodes on what it took to get to the historic Demo-2 launch in May 2020.
For this episode, we go back to March 2019 for the Demo-1 mission. This was the uncrewed version of the Demo-2 mission, instead with a "test dummy" onboard, even if SpaceX doesn't call it that.
Hear the sound of the launch, as well as hear of the significance of this mission from the heads of the Kennedy Space Center and Johnson Space Center.
We'll also hear from NASA Administrator Jim Bridenstine on why more innovation is happening now than during the entire Apollo program.

Episode 1105: Apollo 4 - Paving the Way to the Lunar Surface
Saturday Nov 09, 2019
Saturday Nov 09, 2019
In this special edition of Talking Space, we look back into the NASA audio archives and discover a hidden gem that might get lost in United States space flight history.
On November 9, 1967, months after the United States lost three intrepid explorers duing a spacecraft test, The Apollo Progam arose like the mythical phoenix and launched the most powerfull launch vehicle the world had ever seen, the 364-foot tall Apollo Saturn V Rocket.
Apollo 4 set sail from a brand new port, NASA’s Kennedy Space Center from a brand new launch complex, Launch Complex 39, and with the sucesssfull conclusion of the mission some 8 hours 36 minutes and 59 seconds later, restored confidence in the US Human Spaceflight Program.
What is to follow is the post flight press conference for Apollo 4. In attendaence were space flight giants, with names like Robert Seamans, George Muller, Kurt Debus, George Low, and Werner von Braun.
Its a time capsule of sorts, a moment that paved the way for the human exploration of the lunar surface for the first time, but also may give a hint of future events in NASA’s Artemis program.

Episode 1104: Mars Done?
Thursday Feb 21, 2019
Thursday Feb 21, 2019
After examining the current launch log book and going over some significant breaking news with the Mars Exploration Rover Mission and NASA's current lunar aspirations, the team discusses the latest findings from the New Horizons mission. We then celebrate the naming of the European Space Agency's Exomars mission rover. The ExoMars set for a 2020 launch attempt will be called the Rosalind Franklin after the British chemist who helped discover the true nature of the structure of Deoxyribonucleic acid or DNA. Is the Mars One colonization effort finished after its bankruptcy filing or is it simply attempting to respawn? The team does its best to find out. In the final segment, Mark Ratterman observes the passing of one of the Apollo Program's unsung heroes and we ask help in seeking out anyone who may have had an impact on Apollo's success to tell their story on the program. We also mark the untimely passing of space flight historian and good friend, Kate Doolan.

Episode 1102: Apollo 1
Sunday Jan 27, 2019
Sunday Jan 27, 2019
In this special edition of Talking Space, we observe the anniversary of Apollo 1 allowing the crew to tell their own story and talk to us through courtesy of the NASA Internet Audio Archive.
While launch preparations for Apollo 1 were underway, NASA had held a press conference with the prime crew of what was then called Apollo-Saturn 204
Command Pilot: Virgil I. Grissom
Senior Pilot: Edward H. White II
and Pilot: Roger B. Chaffee
The newly announced back-up crew was also in attendance:
Back-up Command Pilot: Walter M. Schirra,
Back-up Senior Pilot: Donn F. Eisele
Back-up Pilot: R. Walter Cunningham,
Chief of the US Astronaut Corps Donald K. "Deke" Slayton was also made available to the press for this conference.
The purpose of the press event was to introduce the new back-up crew for the flight and to highlight training for the upcoming mission of the then new 3 person spacecraft that would be the lynchpin to get the United States to the Moon.
Rather than recount the doleful events from January 27, 1967, we decided to take a different approach and allow people who may not have been alive or were too young to hear from the astronauts and remember these courageous individuals as they prepared for what was to be the first piloted mission for the Apollo program.

Episode 1011 : Apollo 8 - A Christmas Card From 1968
Monday Dec 24, 2018
Monday Dec 24, 2018
What would Talking Space sound like if it were able to reach across the gulf of time to 1968 fifty years ago and cover the Apollo 8 mission: humanity’s first piloted spacecraft to successful orbit the Moon and return home to Earth?
That is what this episode tries to answer bringing to you some of the historic moments from the Apollo 8 mission, the first to carry humans beyond Earth’s gravity well into deep space to explore the Moon with human eyes and close up photography. This installment makes extensive use of NASA's audio archive from that time period, and we thank the space agency for making these moments in history available for use. It also includes the historic Christmas Message that the flight will be long remembered for. This installment is a tribute of sorts to the individuals known and unknown who made the voyage of Apollo 8 possible 50 years ago.
