Episode 100 of Stories from Space is now Live!

Welcome all! This week’s episode is one that I consider very important. Since the Trump administration was inaugurated, people at NASA were understandably afraid. Uncertainty about the future can do that to people, especially when an unelected, unconfirmed member of government (Elon Musk) begins making seemingly arbitrary cuts to departments, jobs, and spending. Those fears were confirmed with the release of the White House’s Fiscal Year 2026 Budget Request (FY 2006).

In addition to deep cuts, the Budget also calls for the cancellation of programs that NASA has been pursuing for years as part of its “Moon to Mars” mission architecture. These include the Space Launch System (SLS), the Orion Spacecraft, and the Lunar Gateway, which are integral to the Artemis Program and plans to send the first crewed missions to Mars. The Budget also pushes privatization as the solution to every proposed cut, and very deliberately and specifically targets funding for “woke” programs that seek to increase representation in the STEM fields.

To call this Budget a disaster in the making only undersells it. If enacted, it could throw NASA’s entire future into jeopardy. Whereas the Budget specifies that NASA’s only priority should be beating China to the Moon and Mars, it will likely make that goal much harder to achieve. And it would almost surely compromise the agency’s longstanding reputation for leadership in space.

The release of this episode is also a milestone for me and the podcast I launched almost three years ago (July 12th, 2022). Its inception can be trace to an interview I had with the hosts of the Intersection of Technology and Society Magazine (ITSM), Sean Martin and Marco Ciappelli. The funny thing is, they wanted to interview me for an article I wrote for Interesting Engineering titled “Life in 2050: A Glimpse at Education in the Future.”

Afterward, I told them what my main subject was (i.e., space and spacey stuff), and they had me back on for two more episodes to discuss the future of space exploration and exoplanet studies. During the second interview, we announced that I was joining ITSP with a new podcast – Stories from Space!

As such, I wish this episode’s subject were less alarming or depressing. But I promise future episodes (knock on wood!) will be cheerier and feature better news!

Apollo, Vietnam, and Global Problems: A Question of Priorities

Apollo, Vietnam, and Global Problems: A Question of Priorities

Between 1961 and 1973, there was significant pushback from people who lamented the fact that so many resources were being directed toward sending astronauts to the Moon while poverty, social injustice, and inequality were still rampant. Neil Maher, a professor of history at the New Jersey Institute of Technology, addressed this in his 2017 book Apollo in the Age of Aquarius.

According to Maher, the Apollo space program was a source of division among Americans. Whereas supporters viewed it as a way of energizing a country that had lost its way, those opposed saw it as a huge waste of money that should have gone to solving societal problems. As Maher summarized it:

“There was a debate about what America was at the time. Was it a country to spend $20 billion to land two men on a dead rock in space or try to solve some of the problems closer to home on Earth? A lot of grassroots movements argued to use the [NASA] money to solve problems here.”

Episode 90 of Stories from Space is now Live!

This week’s episode asks the question, “Are Red Dwarf Star Systems Habitable?” Red dwarf stars, also known as M-type stars, are pretty controversial. For starters, they are the most common type of star in the Universe, accounting for 75% of stars in our galaxy alone. In addition, red dwarfs seem particularly good at producing rocky planets that orbit within their habitable zones (HZs). In fact, of the 31 potentially habitable exoplanets located within a 50-light-year radius of our Solar System, 29 are located within red dwarf star systems.

However, there are also downsides. For starters, red dwarf suns are variable and prone to flare-ups. While the most powerful are emitted from the poles and are unlikely to affect orbiting exoplanets, the fact that these exoplanets are tidally locked with their stars (where one side constantly faces toward the star) means they would still be bombarded by radiation. But then again, there’s research suggesting this radiation could be essential for life to develop. Like I said, it’s a controversial issue, and we simply don’t know… yet!

Episode 87 of SfS is now Live! “The Space Race: Part II”

Episode 87 of SfS is now Live! “The Space Race: Part II”

This week’s episode is the second installment in the Space Race. In the previous installment, we examined how the American and Soviet space programs were locked in a competition to “get there first.” This included sending the first satellites, animals, and astronauts/cosmonauts to space, in which the Soviets obtained an early lead. By the mid-60s, with the Gemini program, NASA surpassed its Soviet counterparts and was poised to make the Moonshot!

From 1966 onward, both NASA and the Soviets pursued the same goal: sending crewed missions to the Moon. While NASA’s efforts were bold and public, the Soviets developed their own plans in secret. In 1969, history was made when Neil Armstrong and Edwin “Buzz” Aldrin became the first humans to set foot on the lunar surface. They would be followed by no less than six more Apollo missions and twelve astronauts.

With the Space Race officially over, both NASA and the Soviet space program began to set their sights on more long-term goals. They also entered into a new era of cooperation in space, which was demonstrated in the famous “handshake in space” and would eventually lead to the International Space Station (ISS).

Episode 85 of SfS – India’s Space Program – is now Live!

Episode 85 of SfS – India’s Space Program – is now Live!

Hello again! In keeping with the theme of non-western space programs, this week’s episode was dedicated to the Indian space program – the India Space Research Organization (ISRO). Much like China’s space program, which was covered in a previous episode, India’s progress was incremental between the 1960s and 1980s. Nevertheless, the progress they made was foundational and allowed for many impressive developments by the turn of the century.

In addition, like other national space programs, India’s road to space was tied to the development of nuclear technology and weapons. Like China, India has also been forced to develop a number of technologies independently due to non-proliferation agreements and sanctions associated with the country’s nuclear testing. Last but not least, the steps they are currently taking parallel those of NASA and the Soviet space program during the “Space Race.”

This includes the development of heavier and heavier launch vehicles, the deployment of satellites, and sending robotic explorers to the Moon through the Chandrayaan program (“Moon vehicle”) and to Mars through the Mangalyaan program (“Mars vehicle”). All of this has served as a build-up to the creation of a crewed space program.

In the coming years, the ISRO will attempt to send “vyomanauts” to orbit for the first time as part of the Gaganyaan (“celestial vehicle”) program. They intend to follow this with the deployment of a space station, the Bharatiya Antariksha Station, which will facilitate their ultimate goal: sending crewed missions to the Moon and beyond by 2040.

Episode 83 of Stories from Space – China’s Space Program – is now Live!

Episode 83 of Stories from Space – China’s Space Program – is now Live!

This week’s episode was dedicated to one of the fastest-growing space programs in the world. I’m talking about the China National Space Agency (CNSA), which has made several big strides in recent years. Like all major space programs, China’s was conceived amid the Cold War and was related to the development of nuclear weapons. A further incentive was provided when the Soviets and the U.S. began sending satellites and crewed missions to space.

Progress was slow during the latter half of the 20th century due in large part to the chaos caused by the Cultural Revolution (1966-1976). By the 1990s, with the Tiananmen Square Massacre and the collapse of the Soviet Union, the Chinese Communist Party instituted many reforms to ensure its survival. By the 2000s, this extended to its space program, and many bold programs were launched. This included a crewed space program, a robotic exploration program, and plans for a series of space stations.

This culminated in the deployment of the Tiangong modular space station (aka. Tiangong 3), several crewed missions to Low Earth Orbit (LEO), the Chang’e missions reaching the Moon, and the first Chinese mission to Mars (Tianwen-1). In the near future, China plans to create a permanent base in the Moon’s south pole region – the International Lunar Research Station (ILRS). In the coming decades, they also plan to send crewed missions to Mars.

Episode 81 of SfS – An Interview with Sir Peter Beck – is now Live!

This week’s episode was special. By chance, I was able to secure an interview with Rocket Lab founder and CEO Sir Peter Beck (yes, he was knighted!). For those unfamiliar, Rocket Lab is a New Zealand-based commercial space company poised to challenge SpaceX’s near-monopoly over commercial launches. Their first launch happened in 2009 and involved the sounding rocket (a test launch vehicle) Ātea-1 launching from their launch facility on the Māhia Peninsula in New Zealand.

This launch made them the first commercial space company in the southern hemisphere to reach space. Since then, Rocket Lab has launched over 50 smallsat missions using its small-launch Electron rocket and expanded its operations to the U.S. In the coming years, it will introduce the Neutron rocket, a medium-lift launch vehicle that will give them the capability to launch satellite constellations.

Episode 76 of SfS – Where is Everybody? The Waterworlds Hypothesis – is now Live!

Episode 76 of SfS – Where is Everybody? The Waterworlds Hypothesis – is now Live!

In this week’s episode, I returned to the ongoing segment about Fermi’s Paradox (“Where is Everybody?”), which focuses on another proposed resolution known as the Waterworlds Hypothesis. Basically, this theory takes the traditional “follow the water” and asks the question: could rocky exoplanets orbiting distant stars have too much water to be habitable? This theory is based on the current exoplanet census, which indicates that there are many rocky planets several times the size and mass of Earth but with lower densities.

This suggests that volatile elements (such as water) make up a significant fraction of these planets’ mass. If true, this would indicate that these rocky worlds are completely covered in deep oceans. If they don’t possess a dense atmosphere, they would likely consist of an icy outer shell, an interior ocean, and a rocky and metallic core. This is similar to what we see in our own Solar System, where many satellites orbiting the gas giants are thought to have interior oceans beneath their icy crusts.

Like Jupiter’s moon Ganymede, the depths and pressure conditions in these oceans would lead to the formation of an ice layer between the ocean and the rocky, metallic core. If true, this would mean that the very things that could support the emergence of life – hydrothermal activity at the core-mantle boundary – would be missing. Based on the fossil record, this is how scientists believe life emerged on Earth (around deep-sea vents) and what is believed to be happening inside Jupiter’s moon Europa.

However, this does not mean that all Waterworlds can’t support life. In fact, there’s also research that indicates that planets lacking continents and plate tectonics could still support life, perhaps in the form of “space whales“! Still, using Earth as a template, the lack of continents and land masses could mean that evolution would be restricted, and tool-using species may not emerge. So it begs the question: If rocky planets with too much water are the norm, and Earth is an outlier, could this be why we haven’t heard from any extraterrestrial civilizations yet?

Episode 75 of SfS – “The Grand Tour: The Legacy of the Voyager Probes” – is Now Live!

This week’s episode was dedicated to the Voyager 1 and 2 probes, and it was a long time in the making! Launching in 1977, these two probes explored the outer Solar System and accomplished many firsts. This included obtaining the first evidence that Jupiter’s moon, Europa, could have an interior ocean. They also examined Saturn’s rings and got the first close-up look at Saturn’s moon, Titan, and its dense hydrocarbon atmosphere, which led to speculation that liquid methane lakes might exist on its surface.

While Voyager 2 became the first mission to visit Uranus and Neptune, a feat which has not yet been repeated, Voyager 1 conducted the Pale Blue Dot campaign, obtaining the best-known image of Earth. And, of course, they both carry the Voyager Golden Records, which contain sounds and images of Earth and simple diagrams indicating the location of Earth and the Solar System. These records could be the first interstellar message sent by humanity to another civilization or a time capsule for future generations of humans.

The two probes are now in interstellar space, where they continue to operate and return data on the interstellar medium. Regardless of how much time has passed, the Voyager probes will forever remain iconic and their accomplishments legendary. Check out the episode below:

Episode 70 of SfS – The Crisis in Cosmology: What is the Hubble Tension? – is now live!

Episode 70 of SfS – The Crisis in Cosmology: What is the Hubble Tension? – is now live!

This week’s episode deals with a rather pressing matter for astronomers and cosmologists. Shortly after Einstein revealed his Theory of General Relativity in 1916, scientists began pondering how it predicted that the Universe was either expanding or contracting. The debate was settled when Georges Lemaitre and Edwin Hubble confirmed that it was expanding (in 1927 and 1929, respectively). In honor of their accomplishments, the rate at which the cosmos is expanding was named the “Hubble-Lemaitre Constant” (or more commonly, the “Hubble Constant”).

As the field of astronomy expanded and telescopes improved, scientists were able to make distance measurements for objects located farther and farther away. However, these observations were restricted to objects within 4 billion light-years due to the way Earth’s atmosphere distorts light. Depending on the distances involved, astronomers relied on different methods, which came to be known as the “Cosmic Distance Ladder.” In addition to determining the age and size of the Universe, these measurements allowed astronomers to refine their estimates of the Constant.

The Hubble Space Telescope revolutionized astronomy by gradually pushing the boundaries of the “observable Universe” to less than 1 billion years after the Big Bang (13 billion light years!) That’s when scientists noticed some discrepancies. Not only did they learn that the rate of expansion had accelerated over time, but distance measurements to objects located 13 billion light-years away (the earliest galaxies) yielded different values than local measurements. This came to be known as the “Hubble Tension” or the “Crisis in Cosmology.”

While it was hoped that the James Webb Space Telescope would resolve this crisis, its observations have only confirmed that Hubble was right on the money! The crisis endures, and scientists are seeking answers. Is Einstein’s Theory of General Relativity, which is foundational to our cosmological models, wrong? Or are there additional physics/forces at work that we haven’t yet accounted for? Once we know that, we’ll know how just about everything in the Universe works!
