Episode 1804: On A Quesst

Épisode 329

vendredi 19 juin 2026 • Durée 01:12:40

When the Russian crew on board the ISS decided to perform an unusual procedure on the station’s Zvezda module, it caused quite an agreeable break in the routine of the day on board the orbiting laboratory. The crew on the US segment entered an emergency evacuation posture aboard their Crew Dragon, but all returned to normal after a few hours. The team discusses what happened and why.

The astronauts for the Artemis III mission were introduced to the world at NASA’s Johnson Space Center in Houston, TX, with much fanfare and some controversy: No female astronauts were named to the crew. Was this just a normal crew rotation, or was politics at play? The panel looks at the points of contention and weighs in on the Artemis III mission itself.

NASA’s X59 Quesst aircraft, built by Lockheed Martin, is an incredible experiment aimed at reducing a sonic boom to a barely audible thump. If successful, the project has far-reaching implications for the future of civil aviation. Our Mark Ratterman reports on this unique aircraft's first flight tests and its implications.

SpaceX launched something its CEO, Elon Musk, said he would never do: turn SpaceX into a public company and, in the process, turn Musk into the world’s first trillionaire. Heather Smith has been watching this story for us for a while now and delivers some insight into what happens next.

On the heels of the SpaceX IPO, environmental groups in and around Cameron County, Texas, are fighting a plan by the US Fish and Wildlife Service to reallocate land inside the Lower Rio Grande Valley National Wildlife Refuge to SpaceX to support Starship Operations.

Episode:1803 Things That Go Boom in the Night

Saison 18 · Épisode 328

jeudi 4 juin 2026 • Durée 01:06:22

The Talking Space Team gathers around the microphone once again to survey the horizon of spaceflight news—and what an eventful week it has been.

On May 26th, NASA announced a new wave of contracts for its moon base program, along with updates on the progress of Artemis III. We break down exactly what was said during the press event and what it means for humanity's return to the lunar surface.

SpaceX launched its highly anticipated Starship 12 mission on May 22nd, showcasing the brand-new Starship V3 vehicle. While some space news outlets were quick to stamp it as an unqualified success, the actual results were decidedly mixed. As far as debuts go, there is plenty of room for both applause and concern—and we dive deep into the launch.

The biggest, most shocking news of the week took place at Cape Canaveral Space Force Station in Florida. On Thursday, May 28th, a Blue Origin New Glenn rocket suffered a catastrophic explosion on Launch Complex 36, yielding the most powerful rocket explosion since the Soviet N1 moon rocket disintegrated in the late 1960s. This static-test accident sent shockwaves through both Blue Origin and NASA’s Artemis timeline. We attempt to begin picking up the pieces.

Decades ago, NASA's twin Pioneer spacecraft became some of the first human-made objects to chart a course out of the solar system. But as they crossed into deep space, a mystery emerged: both probes were mysteriously slowing down. The effect was later referred to as the . With assistance from the , our resident cosmic detective, Mark Ratterman, goes on the case to solve this historic deep-space puzzle.

Episode 1611: Dissimilar Redundancy

Épisode 319

vendredi 12 juillet 2024 • Durée 01:36:21

NASA has tried to get Extra Vehicular Activity Number Ninety underway since June 13th. The first attempt was thwarted by a space suit comfort issue, the second by a water leak that created a blizzard of ice inside the Quest airlock. Are the Shuttle-Era Extra Vehicular Mobility Units (EMU) or space suits finally showing their age? Also, what about Collins Aerospace and their recent withdrawal from their NASA contract to build the next generation of space suits for the ISS and the Artemis Lunar Program when they indicated back in February that all was going well? We discuss.

On June 17th, the FAA held a virtual public hearing to receive comments concerning SpaceX’s plans to use Launch Complex 39-A and NASA’s Kennedy Space Center to support Starship Super Heavy Launches. We discuss what occurred during the session and the fallout from statements put into the record by both Blue Origin and United Launch Alliance.

Talking Space continues our Boeing Space CST-100 Starliner Crewed Flight Test coverage. The team continues to examine the “Starliner is Stuck at the ISS” misconceptions and asks what NASA & Boeing Space could have done to alleviate such headlines. We also look at a posted on Twitter from Jim May, a Boeing Engineer who was part of the NASA-TV coverage, of why “Calypso” remains on the ISS. The basis of his discussion comes from the . Heather Smith mentions the observations of a NASA flight director and his of how Starliner performed during its first actual safe-haven exercise.

Episode 807: How to Sell a Used Space Station

jeudi 1 septembre 2016 • Durée 59:08

This episode takes off with the successful launch of a United Launch Alliance Delta IV rocket carrying the second pair of satellites for the U.S. Air Force’s Geosynchronous Space Situational Awareness Program (GSSAP). Looking ahead to the company’s next launch for the NASA mission OSIRIS-REX and even further to the test flight of Boeing’s CST-100 Starliner, we also discuss their not-quite-as-high-tech but welcome efforts to upgrade the company’s launch stream for the public. Continuing with the return of crewed spaceflight to American shores, we take a look at the results of the RS-25 engine firing test for NASA’s Space Launch System and upcoming tests for the program intended to take us to Mars. SpaceX’ launch of the JCSAT satellites rounds out a very busy August for the space industry before the month has even concluded. At the other end of the launch process, spacewalkers Jeff Williams and Kate Rubins successfully installed the first International Docking Adapter on the ISS to enable docking of a variety of spacecraft, including the upcoming commercial crew vehicles. As commercial access to the ISS increases there is an idea of extending the life of the station by selling it off when the space agencies involved end their cooperative agreements to keep the orbiting lab afloat. Is this feasible? Are there other options for using the station beyond the current plans and what would it take to make them happen? What is the future of not just the ISS but laboratories in orbit? In the even nearer future, Russia has announced their plans to reduce the amount of cosmonauts on station just after news broke of plans to invest in researching a trip to the moon. Again, is this feasible? We discuss the relationship between dreaming and pragmatism when it comes to space exploration, particularly in the two premier spacefaring nations. After all this speculation on the future of space exploration, we take a look back at the days when America was dreaming and preparing for all of this with the X-15. Mark brings our attention to the White Eagle Aerospace blog with just a little sample of the fascinating histories they are preserving over there. We highly recommend visiting the site, with a warning that you might not be able to pull yourself away for a few hours.

Episode 806: Objects In Motion

vendredi 12 août 2016 • Durée 01:10:51

On our own return to flight episode, we discuss several upcoming events ; NASA’s Osiris Rex, a sample return mission to the asteroid Bennu is scheduled for launch on 8 September 2016. The team looks at the mission objectives and the unique configuration of the United Launch Alliance (ULA) AtlasV carrying the spacecraft. SpaceX too is making news with two upcoming commercial launches out of Cape Canaveral Air Force Station. OrbitalATK is also returning it’s Antares booster to flight next month launching the Cygnus cargo craft from the Mid Atlantic Regional Spaceport at NASA Wallops. We also explore a SpaceNews piece indicating that the USAF awarded two National Reconnaissance Office Launch Contracts for the DeltaIV rocket in 2020 and 2023 with SpaceX mysteriously not even filing a protest. The NASA Advisory Council met during the final week of July and issued a warning concerning the Commercial Crew Program and the dangers of the program falling behind schedule. It may impact US ISS crew access. We also explore completely the recent Government Accounting Office Report on NASA’s Space Launch System and Orion Exploration Vehicle, criticizing budget estimates and schedule. Don’t forget about the Upcoming Pleiades Meteor Shower, peaking on August 11th and 12th If you are inclined, take a look at a Kickstarter project to help restore the observatory at the Lowell Observatory in Flagstaff Arizona where Clyde Tombaugh discovered the dwarf planet Pluto.

Episode 805: Changing of the Guard

Saison 1 · Épisode 1

samedi 16 avril 2016 • Durée 59:54

The Kepler Spacecraft ran into trouble last Friday but thanks to heroic effort by the team at NASA’s Jet Propulsion Laboratory, Kepler’s search for Exoplanets can resume. We discuss the SpaceX Dragon Cargo Resupply Mission 8 and it’s cargo specifically the Bigelow Expandable Activity Module (BEAM) to be attached to the International Space Station. SpaceX also proved at least part of their business model by landing the first stage of their Falcon 9 booster on a drone ship. We discuss the implications. At the 32nd Space Symposium, United Launch Alliance and Bigelow Aerospace announced a partnership to loft Bigelow’s B330 expandable modules in 2020, thus creating a new independent space station separate from the ISS without NASA. The team looks at this groundbreaking deal. ULA was also making news this week at the Northeast Astronomy Forum (NEAF), presenting it’s blueprint for a cis-lunar economy once more independent of NASA. All of this looks at space not just a place for exploration but economic opportunity, the team discusses and explores what a future could look like.

In the second half of the show, the team opens up part one of it’s NEAF roundup with of the and of The second half of our NEAF roundup will be coming up in Episode 806.

Episode 804: What Price The Moon?

lundi 4 avril 2016 • Durée 47:08

A new episode and a new crew make their way to the international space station, we highlight the members of Expedition 47 and Astronaut Jeff Williams who will assume command of the station under Expedition 48, and break the US endurance record for time in space during this increment. Only weeks after they have wrapped up the OA4 mission, OrbitalATK is is poised to launch the Cygnus cargo craft the SS Rick Husband to the ISS. We profile one of its experiments the Spacecraft Fire Experiment or SAFFIRE which will study how fires develop and spread in a confined space. Could the US establish its own lunar base by 2022? NASA Ames Astrobiologist Chris McKay seems to think so, and do it for $10 Billion, about the price of a US Aircraft Carrier. The base according to Dr. McKay’s would be established under the McMurdo Antarctic base model, and could be set up rather quickly. Dr. McKay’s paper was first published in the New Space Journal and in light of ESA’s Lunar Village concept we discuss the merits of both ESA’s and Dr. McKay’s vision.

Episode 803 Two Deserts, One Sky

lundi 14 mars 2016 • Durée 51:00

In a departure from our usual fare of space news and policy, this week we took some time to contemplate the skies. Danielle Adams, a doctoral candidate at The University of Arizona in the School of Middle East and North African Studies with a minor in the School of Anthropology stopped by to discuss her current project with us. Two Deserts, One Sky is a project in cultural astronomy connecting the present day desert sky in Arizona across time to the desert skies observed by Arab cultures between the 9th and 12th centuries CE. Danielle weaves the stories recorded by these past cultures in with instructions on how to view the asterisms in the night sky with naked eye observing. In this episode, we speak with Danielle both about Two Deserts, One Sky and how her interest in astronomy and Arab culture led her to the pursuit of this project.

We often speak about the importance of NASA in the community on our show, and this episode provided us with an opportunity to showcase how NASA supports not only those in the STEM fields, but important social science research as well. Two Deserts, One Sky is funded as an outreach project by NASA through the Arizona Space Grant Consortium, along with The University of Arizona’s School of Middle East and North African Studies and the School of Anthropology.

Episode 802: Ripples on the Cosmic Pond.

mardi 23 février 2016 • Durée 51:56

This week we take a journey from the halls of Congress out through our solar system, and then journey out to a point 1.3 billion light years away from home. On February3rd, the Space Subcommittee of the House Committee on Science, Space, and Technology met to discuss the current status of NASA’s Journey to Mars, and how it may survive past the current presidential administration. We examine the winners and losers in the 2017 NASA budget proposal. NASA announces the Exploration Mission 1 Launch Director and we discuss the Cygnus OA-6 Mission launch delay.

The Year In Space increment on board the International Space Station is coming into the home stretch, while back on Earth, the primary mirror of the James Webb Space Telescope (JWST) is completed.

European Space Agency’s Rosetta mission continues, but without the Philae lander that made landfall on Comet 67P in November. There has been no response from Philae since July and ESA has announced they will stop trying to contact the spacecraft. We discuss some of the highlights and lessons learned from this milestone mission. NASA releases a terrain map of Pluto’s ‘heart’ region, based on New Horizon’s spacecraft data , revealing a few big surprises.

The final story: the discovery of gravitational waves from the collision of two massive black holes. These waves reached our own planet this past September and were detected by the freshly-upgraded advanced providing the first proof of parts of Albert Einstein’s theory of general relativity. What does this mean and why is it so exciting? We break it down for you

Episode 801: Not to Mention...

vendredi 5 février 2016 • Durée 01:01:58

This season premiere kicks off with a look at the past, starting with the NASA tragedies that still loom large today, particularly with the 30th anniversary of STS-51L last week. Moving a bit closer to the present, we go over some of the most notable stories of 2015 and discuss what they might mean for the future, from the dazzling images of Pluto from New Horizons to the (sometimes literal) highs and lows of commercial spaceflight. Over our hiatus, SpaceX in particular had some major accomplishments as well as another attempt to land on their ocean barge, Of Course I Still Love You (OCISLY), to learn from, and we speculate on what this could mean for their future. Meanwhile, the omnibus spending bill for 2016 passed and was signed into law, and for once there was a lot of good news for NASA. We delve into some of the details, how this happened, and what this means for NASA missions and the American space industry moving forward. This brought us into this year and the extraordinary efforts by the team building and testing the James Webb Space Telescope a couple of weeks ago.

Also in January, our own Kassy Tamanini and her partner and special guest John Wood were among the first to participate in a Meteorite Hunting Boot Camp, led by good friend of the show and past guest Geoff Notkin. Love meteorites and always wanted to know the nitty gritty details of the experience? These neophytes share what they learned, how it felt, and what it’s like to visit your first strewn field. If this convinces you to try it yourself, you can sign up for the next Boot Camp, coming up this May (spaces are running out quickly, though, so get on it or sign up for Aerolite emails to learn about future events, and don’t forget to tell them we sent you).
