Many of us have visited the various displays of space shuttles around the US, and it's always a spectacular sight. The shuttle orbiter was huge, and seeing in any configuration is inspirational. Notably, the California Science Center is completing a display of the Endeavor in a launch configuration, which is unique among shuttle installations. But the very first shuttle mockup ever constructed will soon go on public display in its birthplace in Southern California, the city of Downey. This is where North American Rockwell, the builder of all the shuttles, was located until they were absorbed by Boeing decades ago. It was in the Rockwell facility that the first wood-and-aluminum mockup of the shuttle was built, and it's been stored until this day under the control of the Columbia Memorial Space Center. Of special interest: besides its uses as a technical simulator, this mockup was what closed the deal between NASA and Rockwell to build the shuttles and inspired many in Congress to support the program. The museum's Executive Director and President, Ben Dickow, joins us to talk about this magnificent, full-sized shuttle mockup, its history, and future plans. Headlines: • SpaceX's Crew-8 mission returned to Earth after a record-breaking 235 days in space, but one crew member remains in the hospital for additional medical checks • Boeing's Intelsat satellite broke up in geosynchronous orbit, creating around 5,000 pieces of space debris, posing potential long-term threats to other satellites • India announced plans for Chandrayaan-4, a lunar sample return mission targeting the Moon's south pole in 2027-2028 • Chinese company Deep Blue Aerospace aims to start offering space tourist flights by 2027 on a suborbital rocket and capsule that resembles a hybrid of SpaceX's Dragon and Blue Origin's New Shepard Main Topic - Interview with Ben Dickow: • The Columbia Memorial Space Center in Downey, California houses Inspiration, a full-scale wooden mock-up of the space shuttle built by Rockwell International in 1972 • Inspiration was used as an engineering tool and to help secure the shuttle contract for Rockwell, impressing both NASA and Congressional leaders who visited • The mock-up features highly detailed interiors, including a crew cabin, flight deck, and cargo bay • After being mothballed for years, Inspiration was recently moved to the Columbia Memorial Space Center for display in a new building • Southern California will soon have the first and last space shuttles on display, with Inspiration in Downey and Endeavour in Los Angeles • Ben emphasizes the importance of preserving the shuttle's history and using it as an educational tool to inspire future generations of engineers and scientists • The emotional power of seeing a space shuttle up close and the human stories behind its creation are key to the exhibit's impact Hosts: Rod Pyle and Tariq Malik Guest: Ben Dickow Download or subscribe to this show at https://twit.tv/shows/this-week-in-space.

This week, we're diving deep into some really clever and cutting-edge tech for Martian habitats... made from fungus! Dr. Lynn Rothschild of the NASA Ames Research Center has been working for years on how mushroom mycelia might be utilized as a habitat-building resource. It's quite fascinating--the organic material can be used to make bricks, to create shaped structures, and even to create an "astropharmacy" to supply certain compounds needed by the crew of a Mars excursion! And it is sufficiently enticing that NASA's NIAC innovation program has given her no less than five grants (which are not easy to get!) to study the possibilities. Join us for this really engaging and blue-sky conversation! Headlines: • ISS has been experiencing a slow air leak, increasing from 0.2 pounds per day to 3.7 pounds per day, causing concern for NASA's Office of the Inspector General • Jupiter's Great Red Spot has been shrinking and "pulsing" over time, as observed by the Hubble Space Telescope, with scientists predicting it will eventually stabilize as a smaller, circular storm • A rare G4-class solar storm triggered widespread auroras visible at much lower latitudes than usual, with NOAA issuing warnings to protect power grids and communication systems Main Topic - Living in Martian Mushrooms: • Dr. Rothschild explains synthetic biology as creating something new with biology, either by altering existing organisms or creating new ones from scratch • The concept of using fungal mycelium for off-world habitats originated from a student project to create a biodegradable drone body • Mycotecture involves growing habitats and structures using mycelium, which can bind various materials like sand, regolith simulant, and wood chips • The properties of mycelium-based materials can be tuned by adjusting the substrate and post-processing, ranging from styrofoam-like to hardwood-like consistencies • Dr. Rothschild's vision for a stable off-world habitat includes using cyanobacteria to process atmospheric gases and minerals, which would then feed the fungi used in construction • Cross-contamination concerns on Mars are addressed, with the lack of liquid water on the surface making it unlikely for introduced organisms to thrive • Additional applications of mycelium-based technology include biomining, water filtration, and even food production • Dr. Rothschild also discusses the Astro Pharmacy project, which aims to develop an on-demand drug production system for astronauts • While these technologies have significant potential for Earth-based applications, developing them for space allows for more freedom to explore revolutionary ideas without existing infrastructure constraints Hosts: Rod Pyle and Tariq Malik Guest: Dr. Lynn Rothschild Download or subscribe to this show at https://twit.tv/shows/this-week-in-space.

It's a question that rivals the meaning of life itself: which is better, Star Trek or Star Wars? Of course, they are very different, and that's really the core of it--one is a sweeping fantasy adventure incorporating the "Hero's Journey," while the other is a science fantasy wrapped around a morality play. In the end, we love them both. But there is a bit of cultural (and perhaps generation) divide here, and someone has to put Tariq in his place. Join us for this civilization-shattering conversation! Headlines: NASA's Voyager 2 spacecraft, now 12.8 billion miles from Earth, had to shut down its plasma science instrument due to power constraints. The instrument was the last of its kind still functioning on either Voyager spacecraft. United Launch Alliance (ULA) successfully launched its second Vulcan Centaur rocket, despite an apparent nozzle failure on one of the solid rocket boosters. The rocket carried a mass simulator in place of the delayed Dream Chaser spaceplane. The Sun unleashed an X9.05 solar flare, the strongest directed at Earth since 2017. The resulting coronal mass ejection (CME) could potentially trigger intense auroras visible at lower latitudes this weekend. Main Topic - Star Trek vs. Star Wars: Rod and Tariq share their personal experiences with both franchises, discussing their first encounters with Star Trek and Star Wars and how the franchises have evolved. They compare the intellectual aspects of both universes, with Star Trek often focusing on morality plays and Star Wars being more of a fun, fantasy-driven space opera. The hosts discuss the acting in both franchises, highlighting standout performances and the impact of certain characters and actors. They examine the iconic spaceships from each universe, noting that Star Trek ships like the Enterprise are more recognizable and have had a more significant cultural impact compared to Star Wars ships, with the exception of the Millennium Falcon. Rod and Tariq argue that Star Wars has had a more significant impact on popular culture, while Star Trek has been more influential in inspiring real-life space exploration and scientific careers. They conclude that both franchises have their merits and have played essential roles in getting people excited about space and science fiction.

NASA's planetary exploration program is in trouble. The Mars Sample Return program is verging on cancellation, and the VIPER mission to the moon already has been. Both are critical precursors to human exploration of these places, as Dr. Jim Bell of Arizona State University will tell us. We need to know more about the surface of Mars--with direct, in-the-lab studies of Mars rocks--and we certainly need to understand where the volatiles--another name for water and other resources of value--are on the moon. And, if you're the US government, you'd like to do both before China does--which is likely not far off. Does it matter who achieves these things first? And specific to the US, what role might private companies and individuals play in the drama? Headlines: SpaceX's Crew-9 mission is set to launch two astronauts to the International Space Station on Saturday, September 28th, with the primary objective of bringing back the Starliner astronauts who have been on the station for an extended period. A Seattle-based company, Iradian Aerospace, has unveiled plans for a new reusable orbital spaceplane that will utilize a revolutionary two-mile-long sled launch system. Earth is set to temporarily capture a small asteroid, 2024 PT5, which will remain in close proximity to our planet from September 29th to November 25th, providing scientists with an opportunity to study a near-Earth asteroid up close as it performs a de-facto flyby. Main Topic - Discussion with Dr. Jim Bell: Jim Bell discusses his early fascination with space exploration, inspired by the Apollo missions and Carl Sagan's acclaimed 1980s series "Cosmos," which led him to pursue a career in planetary science. The decadal survey process is explained, highlighting how it helps align the scientific community's priorities with NASA's mission planning and funding decisions. The challenges faced by the Mars Sample Return mission are discussed, with Jim expressing optimism that NASA will find a way to overcome the current budgetary hurdles and complete this groundbreaking mission. The cancellation of the VIPER lunar rover mission is addressed, with the hosts and guest emphasizing the importance of this mission for future human exploration of the Moon and the need for more transparency in NASA's decision-making process. Jim shares his perspective on the increasing involvement of commercial space companies in planetary exploration, stressing the importance of developing sustainable business models to ensure the long-term viability of these ventures. The conversation touches on the balance between NASA's priorities, such as the Artemis program, and the funding allocated to robotic scientific missions, with Jim highlighting the need for better communication and collaboration between the human spaceflight and robotic exploration divisions of NASA.

Starliner is back and, by all accounts, could have returned with its crew had it been necessary. However, with NASA's "safety forward" approach prevailing, the spacecraft landed uncrewed on September 6, three months after it docked with the International Space Station. Now, the work begins to try to solve the problems- largely software changes, dealing with balky thrusters, and helium leaks- so that the Starliner Crew 1 can fly next year. But how did we get here? What's NASA's take on the latest Starliner mission? And, perhaps above all, how will Boeing approach the program moving ahead? We'll bring you the latest and greatest--and fear not, we have Tariq here to keep us fair--on what's going on with Boeing's Starliner CST-100 spacecraft. Headlines • For the first time, a commercial crew flew above low Earth orbit on SpaceX's Polaris Dawn mission, setting records for the highest spaceflight by female astronauts and the first commercial spacewalk by anyone. • The FAA says it won't clear SpaceX's Starship Flight 5 from Boca Chica, Texas until November due to environmental concerns, frustrating SpaceX as they aim to conduct orbital refueling tests and prepare for lunar missions. Starliner's Return and Future • Boeing's Starliner spacecraft finally returned on September 6th, three months after it launched, facing challenges such as thruster overheating, and in some cases outright fgailure, and a GPS dropout during reentry. • Rod and Tariq discuss the cultural differences between Boeing and SpaceX, with SpaceX embracing a more iterative, failure-tolerant approach that allowed them to innovate faster. • They debate whether Boeing's traditional aerospace culture and cost-cutting measures contributed to Starliner's issues and examined the effects of the company's lack of transparency during the mission. • Despite the challenges, Starliner demonstrated its ability to survive an extended mission and NASA remains confident that Boeing will fly out its Commercial Crew contract. • The future of Starliner may involve private missions to upcoming commercial space stations, but standardizing spacesuits across different spacecraft will be crucial for crew safety. • While Starliner faced setbacks, Rod and Tariq emphasize the importance of having multiple crew transportation systems to ensure continuous access to space.

It's been said that Mars ain't the kind of place to raise your kids, and that's certainly the assertion of the popular 2023 book, "A City on Mars" by Kelly and Zack Weinersmith. In fact, they question the future of settling humans off Earth in its entirety. Certainly, it will be challenging, but is it impossible? Are there reasons we should not go? We gathered together two of our favorite experts on the topic, Dale Skran, the COO and SVP of the National Space Society, and Mr. YouTube himself, Isaac Arthur—who has produced maybe 100 hours or more of well-regarded videos on the subject—to discuss the book and our prospects for rational, realistic space settlement plans. Join us! "A City on Mars" takes a skeptical and humorous look at space settlement, questioning our readiness for having children in space, building space farms, and creating independent space nations. Dale Skran wrote a comprehensive 40,000-word review of the book, acknowledging its depth while disagreeing with many of its conclusions. He believes the book represents the current stage of opposition to the increasingly realistic prospect of space settlement. The hosts discuss the potential benefits and resources available in space, with Dale and Isaac emphasizing the vast opportunities and the need for reasonable regulation to facilitate space development. The challenges of human reproduction in space are examined, with the hosts agreeing on the importance of further research and the need for artificial gravity experiments on space stations. The potential for conflict and war in space is explored, with Dale arguing that space settlements will likely be more resilient and less vulnerable than Earth-based cities due to their designed defenses against natural and artificial threats. The hosts critique the book's pessimistic view of space settlement and its suggestion to wait centuries until humanity has solved all its problems before venturing into space. They argue that space development and solving Earth's issues can and should happen concurrently. Dale Skran highlights an interesting idea from the book: the possibility of a dual life cycle for settlers, with reproduction occurring in 1G spin gravity settlements while adults spend much of their time working in low-gravity environments like the Moon or Mars.

If you saw the movie "Gravity," you have a sense of the dangers of orbital debris—and the risk is very real. More than 25,000 objects over four inches in diameter are tracked by the US Space Force, and millions of others are smaller or untracked—everything from derelict satellites to dead rocket stages to bits of shrapnel and even just chunks of frozen rocket fuel is there. And even something the size and mass of a paint chip, traveling at orbital speeds, can take out a window of a spacecraft. We're joined by Dr. John Crassidis from the University of Buffalo, an expert in orbital debris and its dangers. Look out below; this is going to be a hot one! Headlines: SpaceX Falcon 9 launch failure investigation underway after engine explosion during upper stage relight James Webb Space Telescope celebrates 2nd anniversary with new "Cosmic Penguin" image Boeing Starliner return date still uncertain as NASA and Boeing review data Mailbag: Zaheer Mohammed congratulates the National Space Society's Ad Astra magazine on winning the Marcom Awards in 2023 Main Topic: Orbital Debris Discussion with Dr. John Crassidis Orbital debris defined as anything in space that is no longer useful, ranging from paint flakes to rocket bodies Debris moves at extremely high speeds (17,500 mph), making collisions highly destructive Kessler Syndrome: cascading collisions could render low Earth orbit unusable within 50 years if debris growth is not slowed Approximately 47,000 tracked objects softball-size or larger, with millions more smaller pieces Challenges in tracking debris due to limited coverage, object tumbling, and modeling uncertainties Ownership and responsibility for debris removal complicated by lack of international agreements Current remediation techniques not feasible due to cost and technological limitations Urgent need for debris mitigation through international cooperation and improved satellite design Future threats extend beyond low Earth orbit, with debris already accumulating around the Moon Importance of investing in research to develop effective debris removal technologies Hosts: Rod Pyle and Tariq Malik Guest: Dr. John Crassidis Download or subscribe to this show at https://twit.tv/shows/this-week-in-space.

For many of us, dark matter and dark energy are two of the least understood areas of cosmology and astrophysics. This week, we invited Alina Kiessling and Jason Rhodes, both Research Scientists at NASA's Jet Propulsion Laboratory, to explain these concepts and their broader implications for cosmology, exoplanet research, and more. Both of them are working on major space telescope projects to research "dark physics," as they will explain. Guest co-host Isaac Arthur asks compelling, comprehensive questions about physics and cosmology while Rod asks things like "is dark energy dangerous?" because, let's face it, someone has to ask the dumb questions. Join us for the fascinating deep dive into dark forces! Headlines: Chinese rocket startup Space Pioneer accidentally launched a rocket during a static ground test, highlighting the unpredictable nature of rocketry. SpaceX and Jared Isaacman's Polaris Dawn mission, set for July 34th, 2024, aims to conduct the first private spacewalk and set a new orbital altitude record of 870 miles. NASA announced that Boeing's Starliner spacecraft is in good enough condition to stay at the International Space Station for at least 45 days despite ongoing investigations into malfunctioning thrusters and helium leaks. Main Topic - Understanding the Darkness: Guests Jason Rhodes and Alina Kiessling, both Research Scientists and Astrophysicists at JPL, share their backgrounds and how they met through their shared passion for cosmology.
