Episode 69 of SfS – Rendezvousing with an Interstellar Object (with Dr. Alan Stern) – is now live!

Hello all, it’s been a while, I know. Life has been crazy lately. Luckily, I’ve managed to find the time to podcast again. For this latest episode, I had a conversation with Dr. Alan Stern, an astrophysicist from the Southwest Research Institute (SwRI) and the Principal Investigator of NASA’s New Horizons mission. In a recent paper, Stern and his colleagues performed a concept study for an Interstellar Object Explorer (IOE), a mission that could rendezvous with interstellar objects (ISO).

In 2017, the first-ever ISO detected passed through our system – ‘Oumuamua – leaving astronomers intrigued and baffled. Based on the available data, the object defied classification, leading to some rather exotic explanations! Two years later, a second ISO (2I/Borisov) was detected, which was clearly identified as an interstellar comet. In the near future, the Vera C. Rubin Observatory will become operational and will begin detecting dozens of ISOs a year.

Hence the desire for a spacecraft that could rendezvous with the next ISO that graces us. As Stern and I discuss, an IOE mission could have profound implications for astronomy, cosmology, and astrobiology. Studying ISOs would tell us a great deal about other star systems without actually having to go there. And if just a tiny fraction of those happened to be debris from an extraterrestrial civilization, as Prof. Loeb has suggested, the implications would be astronomical (no pun!)

Episode 68 of SfS – The STASH Experiment and Hibernation Technology for Space, with Dr. Ryan Sprenger – is now Live!

Episode 68 of SfS – The STASH Experiment and Hibernation Technology for Space, with Dr. Ryan Sprenger – is now Live!

This week, I sat down with Dr. Ryan Sprenger, the Senior Research Physiologist at Fauna Bio Inc., a California-based biotech company specializing in genomics research. Sprenger and his colleagues have developed a new concept for testing hibernation in space, the Studying Torpor in Animals for Space-health in Humans (STASH) experiment. Their concept was selected by NASA’s Innovative Advanced Concepts (NIAC) program for Phase I development this year.

With NASA’s support, Sprenger and his team will develop a technology demonstrator that will be sent to the ISS. Their concept has the potential to revolutionize space exploration by allowing astronauts to enter synthetic hibernation during the long voyage to Mars and beyond. In essence, astronauts could sleep for the duration of long-term spaceflights, reducing the physiological impact of exposure to microgravity and radiation and the psychological impacts of months spent in a cramped spacecraft.

It will also reduce the amount of supplies missions need to bring along and the amount of waste produced. It will also have applications here on Earth, helping to mitigate aging, disease, and genetic disorders. Follow the links below to learn more!

Episode 66 of SfS – The Cosmic Philosopher: Konstantin Tsiolkovsky – is Now Live!

Episode 66 of SfS – The Cosmic Philosopher: Konstantin Tsiolkovsky – is Now Live!

This week’s episode is dedicated to the life, times, and enduring influence of Russian rocket scientist, philosopher, and cosmologist Konstantin Tsiolkovsky (1857-1935). To many, he’s known as the “father of rocketry and astronautics,” whereas others credit him with being one of the “forefathers,” alongside Hermann Julius Oberth, Robert Esnault-Pelterie, and Robert Goddard (namesake of the NASA Goddard Spaceflight Center).

Regardless of titles, Tsiolkovsky’s influence was immeasurable, and his contributions to science are still felt today. His many treatises on spaceflight, his famous “Rocket Equation,” and his designs for rockets and space stations remain foundational to spaceflight. His speculations about the future of humanity in space inspired generations of futurists, rocket scientists, and science fiction writers – in particular, Sergei Korolev and Werner von Braun, the lead Soviet and German-American rocket engineers during the Space Race.

In addition, Tsiolkovsky’s philosophical ideas were groundbreaking and anticipated future developments, such as the Search for Extraterrestrial Intelligence (SETI) and the Fermi Paradox (“Where are all the aliens?”). For those who believe humanity’s future lies in space, Tsiolkovsky was a pioneer and progenitor who was ahead of his time. As he famously said, “Earth is the cradle of humanity, but one cannot remain in the cradle forever.”

Episode 65 of SfS – Mars by 2040? Why Must We Wait? – is Now Live!

This week was a bit of a treat for me because it allowed me to talk about something that has been unfolding over at NASA for many years. As a science communicator, I have been privileged enough to watch it unfold and have had the opportunity to comment along the way. I am referring to NASA’s long-held plans for sending crewed missions to Mars in the next decade and the many decades’ worth of planning that went into it.

Since 2010, the plan has been to send missions back to the Moon in this decade, build habitats and other infrastructure there, and use it as a testing ground to prepare for Mars. The next step was to send the first crewed mission in 2033, followed by additional missions every 26 months (coinciding with Mars being at its closest to Earth). While there have been doubts for years that NASA could accomplish this goal in that timeline, it was announced this past summer that 2033 won’t happen.

While a flyby mission could occur that year, a crewed mission where astronauts land on the surface is not likely to happen until 2040 – and that would be an ambitious goal. Meanwhile, China is still hoping to make it there by 2033, and SpaceX wants to land there even sooner. But they aren’t in any position to promise that right now since they are dealing with similar challenges and delays. Check out the episode below to learn more about how we got here and what’s likely to follow:

Episode 64 of SfS – “The Europa Clipper Mission: A Conversation with Dr. Steve Vance” – is now Live!

In this week’s episode, I had the good fortune to sit down with NASA scientist and astrobiologist Dr. Steve Vance so we could talk about NASA’s upcoming Europa Clipper mission. This mission, which was decades in the making, will launch this coming October, sending a spacecraft to Jupiter to explore its satellite Europa. Ever since the Voyager probes flew past Jupiter and its moons in 1979, scientists have speculated that there might be an ocean beneath this moon’s icy crust.

The mission will arrive around Jupiter by 2030, where it will begin making flybys of Europa and studying its surface with an advanced suite of instruments. Among its objectives are the characterization of Europa’s surface, investigating surface plume activity, and determining the existence and chemistry of its interior ocean. Another major objective is the search for potential biosignatures, indications that this interior ocean may harbor life!

We got into all of that and a number of other things – including Europa’s depiction in Arthur C. Clarke’s famed Space Odyssey series. As Vance told me during our chat, Clarke played a role in the mission planning, and (contrary to the monoliths told humanity in his stories) we do have permission to “attempt a landing there.”

Episode 61 of Stories from Space – A Mars Sample Return Mission – is Now Live!

This week’s episode is focused on the upcoming Mars Sample Return (MSR) mission, a joint NASA-ESA venture to send a robotic mission to Mars to collect the Perseverance samples. This will constitute the first sample-return mission from Mars, something that scientists have been planning for decades. In 2028, the mission will launch and is expected to return the samples to Earth no sooner than 2033. Unfortunately, due to recent budget cuts, the mission may be delayed or scaled back significantly.

Meanwhile, China is planning its own sample-return mission as part of the Tianwen-3 mission. This mission will launch in 2028 but is scheduled to return by July 2031. As we enter the new Space Race, it is clear that the brass ring is the Red Planet! But regardless of who secures samples from Mars and returns them to Earth first, the scientific returns will be immeasurable. Much like the Moon rocks returned by the Apollo astronauts, scientists will be able to study these samples for generations using the most cutting-edge instruments available.

These studies could finally answer questions that have remained unresolved since the days of the Viking missions. Was there ever life on Mars? Is there life there today (and where can it be found)? When did it go from being a warmer, wetter environment to the freezing, desiccated world we see today? Check out the episode to learn more:

Episode 60 of Stories from Space – The Dark Universe – is now Live!

Episode 60 of Stories from Space – The Dark Universe – is now Live!

This week was a bit of a treat for me personally since I got to delve into something really astrophysical and theoretical! To break it down, in 1916, Einstein placed the finishing touches on his Theory of General Relativity (GR), which explained how gravity alters the curvature of spacetime, matter and energy are equivalent, and time and space are one. His theory was confirmed almost immediately, but by the 1950s and 60s, astronomers finally had the telescopes they needed to really test GR!

Ah, but there was a snag! When observing massive galaxies, astronomers noticed that their rotational curves suggested there was a lot more mass out there than what they could see. This led to the speculation that the Universe was filled with a mysterious invisible mass (“Dark Matter”) that interacted with “normal matter” only through gravity. The existence of this mass was needed for GR to be correct, which had been confirmed nine ways from Sunday by this point.

In the 1990s, the Hubble Space Telescope provided the most breathtaking and deep images of the cosmos. The primary mission of this observatory was to test Hubble’s Law – i.e., that the Universe is in a state of expansion. When looking back through space and time upwards of 10 billion light-years (or more), astronomers hit another snag. Essentially, the rate at which the cosmos was expanding (the Hubble Metric) was speeding up over time!

This led to speculation that Einstein’s theory about a force that “held back gravity” – the Cosmological Constant, which he described as the “biggest blunder of his career” – was actually correct. This unknown force, “Dark Energy,” became another mysterious phenomenon scientists needed to include in their cosmological models. To this day, neither has been confirmed directly. But next-generation telescopes are coming that could resolve this mystery.

Almost Done!

Almost Done!

Hey all! I have more in the way of novel-writing news. For starters, The Cronian Incident is now just a few chapters short of completion. After over a year of writing, editing, and back and forth with my prospective-publisher, the novel is just about finished. All told, it is now 31 chapters long and just over 85,000 words in length. I anticipate it will be about 100,000 by the time its finished, though I have been known to exceed estimates in the past!

And as per my agreement with my publisher, I have begun working on its sequel. Apparently, publishers like to know the people they sign have more books in them. And they prefer to release sequels within a few months of the first book, to ensure that any buzz they generate with the first release can be capitalized on. Lucky for me I had plans for a second and third novel before my publisher and I started talking, not to mention some spin offs.

So here’s the commercial description for the proposed sequel (i.e. what you’d read on the back of the dust jacket), as well as a rundown on some other ideas I’m working on:

The Jovian Manifesto:

The Solar System is in the midst of a crisis. In the Jovian and Cronian systems, the populations are up in arms, thanks to an inflammatory document that has appeared on the local nets. Known as “The Jovian Manifesto”, this document details how a powerful faction in the Inner Solar System conspired to seize control over the moons of Callisto and Titan and forcibly alter them. Behind the leak is a mysterious personality known only as Clio, who is threatening to release all the details unless the guilty parties come forward.

Back on Venus, a former analyst named Valéria Gallego is called before the Solar Assembly to investigate the Manifesto and its author. In this, she is assisted by Kadera, an infiltration specialist who can get in and out of any location in the Solar System. If they can determine its authenticity, perhaps they can prevent open conflict. But if not, the Inner Worlds may have no choice but to send armed forces to the Outer Worlds to ensure peace and stability.

Meanwhile, a string of violent acts has threatened to bring things ever closer to the brink. For Gallego and all those who are seeking the truth, time is running out…

Luna Invictus:

Now this is a book that doesn’t come with a commercial description, just a general one. But it is set in the same universe as The Cronian Incident and The Jovian Manifesto. Here’s what I am thinking. Basically, I wanted to do a story set on the Moon, ca. the 22nd century, when the Moon is now effectively colonized,,,

Between the European Space Agency (ESA), NASA, the Russians (Roscosmos), India (the ISRO), and China (CNSA), the lunar surface now has multiple permanent settlements. Whereas the ESA and NASA have established themselves at the southern polar region – in a domed settlement in the Shackleton Crater – and the Chinese have established a colony in the northern polar region, the Russians and Indians have claimed the mid-latitudes, where stable lava tubes have allowed for the creation of underground cities.

And on the “Dark Side” of the Moon – that is to say, the side looking away from Earth – are a series of installations known as the Unrestricted Zones. It is here that all kinds of weird research, development and experiments take place. Nanotechnology, biotechnology, quantum computing, and man-machine interface – anything goes in these places! Ever since the explosion in learning that took place during the previous century, places all over Earth and the Moon have become dedicated to pursuing technological progress and integration without restriction.

And it is here that a young man named Frankling Houte is seeking to go. Years ago, his sister – named Constant Houte – chose to undergo a procedure where her organic brain would be augmented by merging it with quantum components. But after all contact ceased, he is determined to find her and return her home. But whereas Franklin fancies himself a brave rescuer, it is his sister who will come to save him.

Transverse:

This story will take place entirely in a generation ship that is making its way towards the nearby star system. Within the confines of this self-contained world, thousands of humans have committed to waiting and working for generations as their massive ship – the Traverse Velocity, which in astronomical terms refers to the speed at which a star moves perpendicular to our line of sight – transports them to an Earth-like world outside of our Solar System.

The location of that world is up for grabs at the moment, mainly because new discoveries are being made all the time. Did you hear about the latest exoplanet discovery, located about 39 light years away and already said to be the “best place to look for signs of life beyond the Solar System”? Between that and new findings that claims how previous discoveries are not likely to be habitable after all, I’ve decided to leave the destination blank until I actually start writing it!

But of course, no story would be complete without some intrigue and big ol’ inciting event! And the way I see it, things begin to go awry when the Captain and crew get notification that one of the passengers has awakened from cryosleep prematurely and disappeared into the ship. Shortly thereafter, one of the crew is found dead in what appears to be a sabotage attempt gone wrong. A ship-wide search begins to find the culprit while the atmosphere quickly devolves into one of paranoia and suspicion.

To make matter worse, the crew becomes aware of another ship that is threatening to catch up and overtake them. It seems that another faction from the Solar System, which was also intent on settling (insert exoplanet here) is now trying to get their ahead of them. What began as a journey to a new world, characterized by hopes and dreams, has become a race to lay claim to a planet. And it appears that the planet may have inhabitants of its own, ones which are not interested in welcoming the intruders.

New Movie Trailer: The Martian

the_martianThe latest trailer for the The Martian has just hit cyberspace! And as you can see, its quite the doozy. Based on the novel by Andy Weir, The Martian tells the story of Mark Watney – a botanist and space engineer who is part of a manned mission to Mars. When an unexpected storm strikes in the course of that mission, Watney is lost during evacuation and presumed dead.

However, the crew soon learns that Watney survived the storm and has been living on the planet ever since. With a return mission expected to take years before it can reach him, NASA must struggle with a terrible dilemma – risk the lives of many astronauts to save one, or let Watney die alone on a distant planet?

I will definitely seeing this movie, but not before I read the original novel! And I can proudly say that after learning about this movie, I ordered a copy of the book a few weeks back and it now sits on my nightstand. I still got finish a few things before getting to it, but I plan to have it read before the movie comes out in October. There is no way in hell I’ll be waiting for this movie to come out on DVD or Netflix!
