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 1506: Shocking Answers to Your Starship Lawsuit Questions
Sunday Jul 02, 2023
Sunday Jul 02, 2023
Talk all you want about the delays caused by repairs/mods to the launch pad and re-certifying the Autonomous Flight Termination System, the real issue that is grounding Starship at Boca Chica is this one thing: The Lawsuit.
You know … the one filed by a consortium of environmental groups and Indigenous tribes against the FAA alleging (based on the observable environmental damage wrought by the April test launch) FAA’s inadequate oversight and review of SpaceX’s plans and operations at Boca Chica.
This time around, Larry Herrin and Gene Mikulka are joined by the guy who accurately predicted that the Starship test launch last April 20th would cause more damage than SpaceX or the FAA’s own calculations predicted in its worst-case scenario. His name is Eric Roesch, and he goes by the Twitter handle @ESGHound.
Turns out, Eric has experience working both the consulting and regulatory sides of the fence in shepherding Programmatic Environmental Assessment (PEA) and Environmental Impact Statement (EIS) documents through the process; knows quite a bit about the related issues; and has some well-reasoned answers to questions like:
- Eric, how do you know so much about this stuff?
- Why did SpaceX want to join the FAA as a co-defendant in the lawsuit?
- What are some of the strategies the Plaintiffs may use to try to win it all (or at least wrangle some additional mitigations that SpaceX will have to implement)?
- How much longer will we have to wait for a decision?
- What is the most likely outcome? Will it be:
- The Plaintiffs win it all, and SpaceX must go back to the drawing board for years while a new Environmental Impact Statement is prepared, reviewed, and revised again and again?
- The Plaintiffs manage to wrangle some concessions, and FAA adds some additional mitigations to the existing National Environmental Policy Act (NEPA) document with which SpaceX must comply?
- Defendants prevail and it’s business as usual under the existing launch license?
The answers may surprise you!
All will be revealed in this episode of Talking Space.

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 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.

In this special edition of Talking Space, we talk to the man who was for many years was the voice of Shuttle Launch Control at the Kennedy Space Center, Mr. Hugh Harris.
Born in December of 1932 he served as an information specialist with the US Army from 1952 until 1954 and graduated from Western Reserve University in Ohio in 1956. Mr. Harris worked as a reporter for a metropolitan daily newspaper, a magazine writer for Standard Oil, and a radio personality at WMTR in Morristown, NJ.
According to his NASA bio, He started his NASA career in 1963 as an information officer at what was then the Lewis Research Center, in Cleveland Ohio ( Now the John H. Glenn Research Center). He was promoted to Chief Public Affairs Officer in 1968 and was transferred to the Kennedy Space Center (KSC) in 1975. ten years later he assumed the role of Deputy Director of the KSC Public Affairs Office.
Harris Earned NASA’s Equal Opportunity Medal in 1979 and was awarded Exceptional Service Medals in 1985 and 1988. He’s also earned a Distinguished Service Award. form the SPacecoast Chapter of Federally Employed Women for 1978-79
Harris retired from NASA in April of 1998 but still volunteers on occasion at the Public Affairs Office. He is the author of the e-book: Challenger an American Tragedy where he recounts his observations of that fateful day in January 1986, and the events thereafter.

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 1004: 'InSight' into NEAF
Saturday May 12, 2018
Saturday May 12, 2018
What do you get after one month away? A boat load of news and some amazing interviews for our return from spring break.
We begin looking at the launches of the last month from all corners of the globe. We check out many of the major launch providers and their most recent missions. We also discuss the recent improvements in the quality of their webcasts and our thoughts on what that means for outreach.
We also discuss the announcement of two new NASA managers. First, NASA's new head of science and of course, the recently confirmed NASA Administrator Jim Bridenstine. We discuss our opinions so far on both of them and what we hope for the future.
Of course we discuss NASA's next Mars lander which is now on its way, Mars InSight, however we get some "insight" from one of the people who worked on it at this year's Northeast Astronomy Forum, or NEAF.
At NEAF, we also hear from the authors of "Bringing Columbia Home" about the recovery efforts after the 2003 Columbia disaster. Plus we bring you an amazing story of a young girl from Cosovo who's taking the US by storm promoting astronomy outreach.
We also have to give a special shout-out to the ESA team working the Bepi Colombo Twitter account, @ESA_Bepi, on taking our wacky suggestion of needing a cute mascot. Make sure to check it out and tweet them if you love it.

Episode 1001: New Season for New Space
Tuesday Jan 23, 2018
Tuesday Jan 23, 2018
Talking Space is turning 10 seasons old...yet most of the topics involve new space surprisingly!
We begin focusing on SpaceX first with the return of CRS-13 and a look-ahead to the Falcon Heavy static fire test. Of course, we address the mystery behind the secret Zuma payload. Did it safely make it to orbit, did it come crashing back to earth, or is there something we're not being told? We get an ISS update including a preview of two spacewalks.
Next in our launch round-up, it's ULA with their NROL-47 mission and SBIRS GEO 4. Then it's over to India for a successful return of the PSLV plus a look at whether India could disrupt the international launch game. We also check out some smaller companies and their big impacts like RocketLab's Electron.
Then it's over to China whose rocket didn't blow up but still sent pieces crashing into the ground near crowded villages. Can the US partner with a country that just throws away rockets near people? We weigh in.
Lastly we remember two amazing astronauts in Bruce McCandless III and John Young who recently passed away.

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.

Episode 914: The Long-Awaited Launch Vehicles
Monday Nov 13, 2017
Monday Nov 13, 2017
Falcon Heavy gets a launch date for very soon, and SLS gets an even further away launch date, along with more in this jam packed Talking Space! On this episode we have a busy launch round-up featuring the Vega rocket, SpaceX, a new Minotaur-C, China bouncing back from failure, and more. We also have the upcoming penultimate flight of the Delta II, a classified SpaceX payload, a first launch from SLC-40 since the AMOS-6 failure last year, and AMOS returning back to SpaceX with a new satellite. We discuss all of this, along with the newly announced launch date for the long-anticipated SpaceX Falcon Heavy launch from LC-39A. However, they also had a bit of a setback with a Merlin engine exploding on the test stand in McGregor, Texas.
We then go into the first hearing for NASA administrator candidate Jim Bridenstine and some of the bizarre questions asked of the controversial candidate. We then go into NASA pushing the launch of SLS most likely to mid-2020, and a report by the NASA OIG on how even that might be unreasonable. Then it's onto names on Mars and a KBO that needs a name. We also must sadly mention the passing of Gemini XI and Apollo XII veteran Richard "Dick" Gordon at age 88. We reminisce on our memories of one of the last of his kind.
