The science of suspended animation


I sold my first non-fiction article!

Back in January, I got in contact with Tony Daniel, the senior editor of Baen books, sent an article proposal, and signed a contract. Around the same time I won the Jim Baen Memorial Short Story award. I think it took him a couple of weeks to realize he was communicating with the same person in the two different email chains. This article was originally going to be posted last month, but he felt it was best not to publish it the same month as my short story “Feldspar.”

Here is the link to the article on the Baen website: “Stasis: The Future of Suspended Animation.”

For this article, I managed to get an interview with Dr. John Bradford, the COO of SpaceWorks, who is pioneering the development of suspended animation techniques with NASA for future human expeditions to Mars.

Here is the full, unedited interview:

Me- “How long could hibernation theoretically be sustained?”

Bradford- “One initial comment that is a bit of semantics, but we like to always clarify. On the term ‘hibernation’: We can’t actually make people hibernate, so prefer terms like “human stasis”, “torpor inducing”, and “metabolic suppression”. Maybe in the distant future through gene therapy/modification, this can be achieved, but right now we are focused on artificially inducing a hibernation-like state via cooling and metabolic suppression. So, we are trying to mimic hibernation, but not achieve it.

We are in the process of evaluating how long we can sustain the low metabolic state. This will ultimately have to be determined through testing, but since we are starting with current practices for Therapeutic Hypothermia, we have a lot of data to evaluate on what is occurring in the body over short 2-4 day periods. Longer periods of up to 14 days has been achieved, but data there becomes much more limited. We also look at animal hibernators as sources of understanding (and inspiration). Bears are a great model since their core temperature doesn’t drop to the extreme conditions most hibernators experience. They can be in torpor for 4-5 month periods. In summary though, we don’t know what the theoretical limit is yet. For our approach, it would not be measured in years. We can benefit a lot in terms of space travel if we can achieve just a few weeks, but ultimately we are looking to achieve months.”

Me- “Are there any plans to test human hibernation in the near future?”

Bradford- “Eventual human testing is on our roadmap and plans. NASA’s NIAC program is not funding us for any medical testing though, only to evaluate if this is possible, identify how we would do this, and quantify the mission impacts if it is feasible (engineering analysis). However, we are getting inquiries from a few investors and looking at non-governmental funding sources to start some specific testing. Note again that we do have medical data from subjects undergoing TH over short periods already, but those were not controlled tests.”

Me- “What is a major medical/engineering hurdle that will have to be overcome before this technology can be implemented?”

Bradford- “I get asked this question a lot and my answer probably changes frequently depending on what aspect I’m currently working on or problem I’m trying to solve. There are certainly challenges, but we are coming up with a variety of solutions or ways to mitigate them, either via a medical approach or engineering it out. The ability to initiate human testing will certainly be a milestone – fortunately I hear from a lot of people that want to volunteer! Transitioning to space-based human testing would be the next big step.

Lastly, I’d say we believe human stasis represents one of the most promising approaches to solving the engineering and medical challenges of long-duration spaceflight. With this technology, a variety of new options can be introduced and applied that address major human spaceflight medical challenges and risk areas such as bone loss, muscle atrophy, increased intracranial pressure, and radiation damage. System-level engineering analysis has indicated significant mass savings for both the habitat and transfer stages. These savings are due to reductions in the pressurized volume, consumables, power, structures, and ancillary systems for the space habitat. This capability is potentially the key enabling technology that will ultimately permit human exploration to Mars and beyond!”

Writing Update- The 2017 Jim Baen Memorial Writing Contest


I am pleased to announce that my short story, “Feldspar,” won the 2017 Jim Baen Memorial Writing Contest. It is an honor to be chosen as the grand prize winner from such a pool of talented finalists.

The contest.

Baen books describes the contest as follows:

“Since its early days, science fiction has played a unique role in human civilization. It removes the limits of what “is” and shows us a boundless vista of what “might be.” Its fearless heroes, spectacular technologies and wondrous futures have inspired many people to make science, technology and space flight a real part of their lives and in doing so, have often transformed these fictions into reality. The National Space Society and Baen Books applaud the role that science fiction plays in advancing real science and have teamed up to sponsor this short fiction contest in memory of Jim Baen.”

If you follow my blog, you can tell why this contest came to my attention. I am a scientist, but my narrow field of research only satisfies a small portion of my fascination for science, space, and innovation. I decided some time ago that the only way I could make a real difference in science (beyond my own research) was to write about it. With any luck, my stories will inspire other scientists to invent what I do not have the time, intellect, or resources to create on my own. Winning this contest means a lot to me.

As the winner, I will be professionally published by Baen Books sometime in June. This will be my first professional publication, so it’s kind of a big deal for me. Along with publication, I will be given a year’s membership to the National Space Society, free admission to the 2017 International Space Development Conference in St. Louis, an engraved trophy, and tons of other prizes. Needless to say, as both a scientist and writer, I am most excited about attending the ISDC conference in May. It will give me the chance to speak to leaders in the field of space development about topics such as living in space, the space elevator, planet colonization, and innumerable other topics of mutual fascination. A previous Baen winner was able to sit next to Buzz Aldrin at lunch *cue two months of giddy excitement*. With any luck, I may be able to discuss my own scientific research and how it could help prevent the muscle atrophy associated with low gravity. I hope to come away from the conference with many new contacts as well as exciting story ideas.

The story.

“Feldspar” is the story of Blake, a lonesome rover operator in the city of San Francisco. With the help of the gaming industry, space exploration has boomed, and Mars has become the largest sandbox game in human history. Over a hundred rovers prowl the surface of the red planet, harvesting regolith for smelting. The iron wire they receive in return is used to 3D print any object these gamers desire.  But they aren’t the only ones on the red planet. When Blake comes across the footprints of a NASA astronaut over a hundred kilometers from the Eos Basecamp, he becomes her only hope of staying alive.

My thanks.

I’d like to thank Bill Ledbetter, the contest administrator, Michelle, the “slusher of doom,” and all the judges, including author David Drake, for choosing “Feldspar” from the slush pile. I worked on “Feldspar” for months, gathering feedback from friends, family, my writers group, and even my uncle Wade, a NASA employee. I appreciate their valuable feedback. This was my first short story contest, and it gives me hope that there is a place and perhaps a need for my unique voice in the world. I will diligently continue my writing, hoping that my vision for the future of space exploration will inspire scientists to make it a reality.
