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 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.

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 1507: A Secret Mission and … OceanGate’s Titan?
Friday Jul 14, 2023
Friday Jul 14, 2023
You may ask, “Why are we talking about the OceanGate Expeditions’ Titan submersible tragedy in a podcast dedicated to space-related stuff?” The commonality with undersea exploration is the lack of Human Commercial Spaceflight Safety Regulations. Do we need more regulation? The team muses about this issue in this episode of Talking Space.
But first, the News Roundup:
- Mark manages to both provide us interesting info as well as to humanize the launch he witnessed of a classified military payload -- the mission designated NROL-68.
- A classified military orbital mission notwithstanding, there’s still lots of news we CAN provide details about in this episode, including the ribbon-cutting ceremony for NASA’s Earth Resource Information Center in Washington, D.C.
- The final flight of the Ariane V, VA261, was postponed during rollout. After an additional weather delay on July 4, the final launch of the Ariane 5 rocket took place on Wednesday, July 5.
- Ecuador and India become the 26th and 27th signatories of the Artemis Accords.
- The Mars Sample Return mission’s cost has skyrocketed, according to a report in Ars Technica. Will it affect the budgets or existence of other planetary research missions? Gene has some insights.
- The Deep Space Food Challenge, an international competition sponsored by NASA to innovate food production for deep space missions, is heading into its final phase. Mark has details.

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 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 1204: From Liftoff to Splashdown
Tuesday Aug 18, 2020
Tuesday Aug 18, 2020
On this episode of Talking Space, we tackle two major stories, the launch of Mars 2020 and the landing of Crew Dragon Endeavour.
We start with the launch of the Perseverance rover and the Ingenuity helicopter. We look at some of the unique items onboard, as well as listen to the launch audio we recorded from a few miles away. In addition to the mission, we talk about what it's like to cover a launch during a pandemic (with special thanks to the 45th Space Wing) and how a Mars spacecraft sterilizer is helping in the fight against COVID-19.
Then it's onto SpaceX and the successful return of the Crew Dragon capsule from the ISS. We look at the successes and some of the items they found need to be improved, including stray boats and possibly toxic hypergolic fuels.
Finally, we debate a tweet by President Donald Trump about the state of NASA. Mark and Gene get into an interesting debate over the state of the space program and who we can thank for where we are today.

Episode 1203: 3 Missions, 1 Planet
Tuesday Jul 28, 2020
Tuesday Jul 28, 2020
On this episode of Talking Space, the main focus is on Mars as three countries send missions to the red planet.
We discuss the United Arab Emirates first mission to the red planet and the implications it has for the country and that part of the world.
We then discuss China's mission which was also launched, their first solo mission to Mars, and discuss where their space program stands right now and if they could become a major player again in space.
Finally NASA is up with their Mars 2020 mission and the Perseverance rover.
We discuss some launch successes and one failure unfortunately for Rocket Labs of their Electron rocket and what it means for their future. We also discuss another delay of the James Webb Space Telescope and what you can do to see Comet NEOWISE before it disappears.
Kat Robison brings us a special piece on a space pioneer you may not have heard of, Ed Dwight. You can read the original article by clicking here.
Finally we remember U.S. Representative John Lewis and his surprising connection to the International Space Station.

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 1101: China Has Landed On the Moon, Whither America?
Sunday Jan 27, 2019
Sunday Jan 27, 2019
The Talking Space Team says hello to 2019 with a wrap up of 2018 launch activities and a very spirited discussion of what the future may bring in the area of commercial space launch here in the US with new major players coming on the field. How will they fair against the international commercial launch services companies long term for new business?
We’ll travel with New Horizons spacecraft to Ultima Thule and recap the flyby that occurred New Years Day 2019 and update about the mission’s progress. We also fly out to check on the progress of the OSIRIS-REx mission orbiting the Asteroid Bennu, and the Mars Insight mission.
We then review China’s and humanity’s first landing on the lunar far side and discuss the implications of this historic moment. However, does it mean that China is now the lead in space or is it an exaggeration? Also, we examine how China handled the coverage of the mission thus far.
All this and more in this first edition of Talking Space for 2019.
