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 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 1301: Three Cheers for Mars
Tuesday Mar 23, 2021
Tuesday Mar 23, 2021
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?

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 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 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 1009: To the Moon, Elon!
Friday Oct 05, 2018
Friday Oct 05, 2018
On this episodes we may be mentioning routine launches but it's anything but routine as we return for a news round-up.
On this episode we begin our launch round-up with some past and present SpaceX launches, including the Telstar-18V launch and the upcoming first RTLS mission from Vandenberg Air Force Base in California. We also check in on our rover friends on Mars, Opportunity and Curiosity. One remains silent while the other deals with a data glitch.
We then move on to the ISS to discuss the recent Japanese cargo vehicle launch, the HTV, aboard an H-IIA rocket. This HTV vehicle, however, has a unique return capability. Hear all about it in the episode. Then, it's what we're calling "hole-gate". A look at the history behind the hole discovered on a Soyuz, how NASA and Russia handled it, and who really could be behind it. We also congratulate Japan on their first successful landing on an asteroid, and why members of the OSIRIS-REx team are watching closely.
Then we get into the big announcement from SpaceX of design changes to the BFR as well as the first private citizen to pay to fly aboard it. Elon Musk is saying 2023 but is that realistic or is it just "Elon Time"? We give our opinions and our thoughts on where the program should go.
Lastly it's a story you'll only hear on Talking Space, about NASA 502. The research plane flying in and out of the airport in Gainesville, Florida, where our own Mark Ratterman works. Find out why a NASA plane from California is in Florida and studying Hurricane Florence and why it has an odd disk underneath it.

Episode 1005: #SaveOppy?
Wednesday Jun 20, 2018
Wednesday Jun 20, 2018
From launch rates to renamings and of course two major announcements from the red planet, it's another jam-packed Talking Space.
We begin with our launch round-up, including China, Japan, and two manned missions. We discuss the return of Expedition 55 and the launch of Expedition 56 and what will make that mission unique. Then we look at SpaceX's recent launches, including their first ever Block 5 launch and what that means. We also look at their future launch plans including launch sites and a staggering number being put out for a launch rate.
We discuss what's going up on SpaceX's CRS-15 mission including more about our favorite creepy face, as well as the OA-9 launch from Orbital ATK, who is getting a new name. Orbital ATK has been acquired by Northrop Grumman to become Northrop Grumman Innovation Systems, and what's behind that deal.
Then we travel to Mars, where we look at the Opportunity rover, or try to as its blanketed by a massive dust storm. Is it dead? Not just yet. Hear from some of the scientists working on the MER program and what they're saying about this unprecedented storm. Plus while staying on Mars, did Curiosity find life? Not exactly, but we discuss a major find from the Mars Science Laboratory.
We finish with a congrats to the Juno team and two fond farewells.

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.
