[Like Kurt Gödel and Alan Turing] I am also besotted with mathematics… I am absolutely struck with the power of mathematics, and that’s why I’m a theoretical physicist. If I want to answer questions, I love that we can all share the mathematical answers. It’s not about me trying to convince you of what I believe or of my perspective. We can all agree that one plus one is two, and we can all make calculations that come out to be the same, whether you’re from India or Pakistan or, you know, Oklahoma.
Magnificent On Being interview with cosmologist and theoretical physicist Janna Levin, who studies black holes, is the author of a bewitching novel about Kurt Gödel and Alan Turing, and has written beautifully about the relationship between genius and madness. (via explore-blog)
You may remember that back in February, four crew members lived and worked inside our Human Research Exploration Analog (HERA). That crew, made up of 4 women, simulated a 715-day journey to a Near-Earth asteroid. That 30 day mission helped our researchers learn how isolation and close quarters affect individual and group behavior. Studies like this at our Johnson Space Center prepare us for long duration space missions, like a trip to an asteroid or even to Mars.
We now have another crew, made up of four men, living and working inside the HERA. This is the spacecraft’s 10th crew. The mission began on May 3, and will end on June 1.
The crew members are currently living inside this compact, science-making house. But unlike in a normal house, these inhabitants won’t go outside for 30 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to internet. The only people they will talk with regularly are mission control and each other.
The HERA X crew is made up of four males selected from the Johnson Space Center Test Subject Screening (TSS) pool. The crew member selection process is based on a number of criteria, including the same criteria for astronaut selection. The four would-be astronauts are:
Ron Franco
Oscar Mathews
Chris Matty
Casey Stedman
Lisa Spence, the Human Research Program’s Flight Analogs Project Manager, explained that ideally they would like the four-person crews to be two males and two females. Due to the applicant pool, HERA IX was an all female crew, and HERA X (this current mission) is all male.
What will they be doing?
The crew will test hardware prototypes to get “the bugs worked out” before they are used in off-Earth missions. They will conduct experiments involving plants, brine shrimp, and creating a pice of equipment with a 3D printer. After their visit to an asteroid, the crew will simulate the processing of soil and rocks they collected virtually. Researchers outside of the spacecraft will collect data regarding team dynamics, conflict resolution and the effects of extended isolation and confinement.
How real is a HERA mission?
When we set up an analog research investigation, we try to mimic as many of the spaceflight conditions as we can. This simulation means that even when communicating with mission control, there will be a delay on all communications ranging from 1 to 5 minutes each way, depending on how far their simulated spacecraft is from Earth.
Obviously we are not in microgravity, so none of the effects of microgravity on the human or the vehicle can be tested. You can mimic isolation to some degree – although the crew knows they are note really isolated from humanity, the communications delays and ban from social media help them to suspend reality. We mimic confinement and the stress that goes along with it.
Scientists and researchers use analogs like HERA to gather more data for comparison to data collected aboard the space station and from other analogs so they can draw conclusions needed for a real mission to deep space, and one day for a journey to Mars.
A few other details:
The crew follows a timeline that is similar to one used for the ISS crew.
They work 16 hours a day, Monday through Friday. This includes time for daily planning, conferences, meals and exercises.
They will be growing and taking care of plants and brine shrimp, which they will analyze and document.
Past HERA crew members wore a sensor that recorded heart rate, distance, motion and sound intensity. When crew members were working together, the sensor would also record their proximity as well, helping investigators learn about team cohesion.
Researchers also learned about how crew members react to stress by recording and analyzing verbal interactions and by analyzing “markers” in blood and saliva samples.
In total, this mission will include 22 individual investigations across key human research elements. From psychological to physiological experiments, the crew members will help prepare us for future missions.

Also, while this is on my mind. In my master’s-level food toxicology class today we discussed various genetically modified crops and watched part of a documentary about them, and as someone with a food science degree I would like to be clear about the following:
The only health risk that has been shown to us throughout twenty plus years of having genetically modified crops as part of the food system is that there is a possibility of introducing proteins that could cause allergic reactions. New strains are required to be tested for this, of course, but that is a practical risk that needs to be closely monitored.
The objection to GM in general should be the patenting of genes and other legal matters; there are a number of crops that have been saved from blight and overall extinction via modification in the past two decades, and much like putting up inaccessibly expensive paywalls to scientific journals, patenting of genes within crops limits our ability within universities, small research companies, etc to make significant breakthroughs to further the scientific progress of humanity.
Furthermore. People think of organic crops as the environmentally-friendly option. If you believe this, please pay attention to what I’m about to say. Current regulations dictate that to have a crop classified as organic the land on which the crop is grown has to have been pesticide-free for a significant amount of time. There is no interim label available to farmers. So what do they do? Do they use no pesticides and take the losses from disease and insects for a decade, waiting for a time in which they are allowed to reclassify their crops in such a way that they can sell them for more money?
Of course they don’t. It isn’t practical. You can say what you like about how the system is structured; I’d personally like to see an interim classification come into play. But what farmers actually do, and states like Montana are feeling the full effects of this–they clear-cut forests and plant their organic crops on entirely new land.
You want to tell me that clear-cutting forests is environmentally friendly? It’s not. Hell, for all that people make a big deal about saving the environment by limiting how much paper they use, paper production is done in a more sustainable manner (because the paper farms replant their trees in a regular cycle so as to not deplete their sources; they don’t just go out and cut down random trees).
There are objections to be had in regards to GM crops on a legal basis. On a scientific one, there isn’t much. Call them frankenfoods all you want; look up what most commercially-sold produce truly looks like in the wild with no modification and you will learn very quickly that all foods have been modified in some way over the years through conventional breeding. We just think of that differently.
Biotechnology is not the enemy. Pseudoscience tells us that this is the case. Pseudoscience also tells us that we should seek out natural supplements instead of medicine, and, well… that’s a rant for another day, but suffice to say it’s an even more dubious proposition.
Don’t buy into it.

Device Rids Buses of Dangerous Pathogens The best place to enjoy a breath of fresh air may be a city bus, if Rice Univ. students have their way. A team of graduating seniors has created a system for public transit that would continually clear the air of pathogens that can lead to tuberculosis (TB), flu and pneumonia. The CityBusters – Joseph Spinella, Jerry Lue, Sundeep Mandava, Grace Ching and Shidong Chen, all seniors – have installed a $500 device on a METRO bus in Houston that has proven effective at killing 99.8 percent of the pathogens that circulate through the air-filtering system. The device, called FluProof, incorporates high-powered ultraviolet lamps that sterilize the air on the fly.
