Steep Learning Curve!

We are learning a lot, and quickly, and moving very rapidly toward building the final high-altitude pressure Mathew l. and I fabricated two helmet mounting rings to work with our new, lightweight 'soft helmet'. More frequent updates are on the Pacific Spaceflight twitter account.

Silent Film of Pressure Suit Test!

Here is some silent video of a pressure suit test, I am in a Bell Jet Ranger helicopter going to just shy of 20,000 feet, but the suit is giving me pressure--through the 45-minute flight--that fooled my body to think that it was at just 11,000 feet! The suit held pressure, dumped my exhaled C02, maintained a good temperature, and gave me enough mobility to work the controls! All A-OK!

"The design of a book is the pattern of a reality controlled and shaped by the mind of the writer. This is completely understood about poetry or fiction, but it is too seldom realized about books of fact. And yet the impulse which drives a man to poetry will send another man into the tide pools and force him to try to report what he finds there..."

Developmental Biology and Human Space Settlement

Today I had occasion to work on a diagram addressing some reproductive issues in the prospect of human space settlement. In particular I feel that early developmental biology will be most likely to be upset by conditions different from Earth's one-g gravity field, which has shaped land animal reproductive biology for over 300 million years. This October, Elon Musk will reveal SpaceX's plan for a city on Mars. I say Bravo! Bold and important! But we will need to learn a lot about our biology on Mars, where 1/3 gravity of Earth will be sure to affect reproduction; and we may have to ensure the health also of our domesticates, plant and animal, who will accompany us to the Red Planet as well! All good reasons to begin research and planning now, as I'm doing in my forthcoming graduate-level technical book "Principles of Space Anthropology".

Immersion Test Photo

A recent immersion test; only the smallest leak from the helmet is visible as tiny bubbles rising from a fitting that just needs a little tightening; the rest of the bubbles are from safety divers. We learn a lot from every test, and so far I've spent 2.2 hours submerged in our various pressure suits!

Serial Explorer

This article in the June 2016 'Men's Journal' describes me as a 'serial explorer by nature'. That's OK with me.

H.J. Muller's 'The Uses of the Past'

I'm reading the most exciting and challenging book I have read for some years, HJ Muller's 'The Uses of the Past' (1952). Muller is a dispassionate historian commenting on the state of 'civilization' at his time, colored of course by his experience of WWII, but still remarkably separated from that catastrophe. His encapsulations of Greece, Rome and the Enlightenment are rich and erudite -- every few pages take me a few days to digest. Highly recommended (for those who can extract themselves from the navel-gazing present)! One passage:

"Science remains the author of our major problem, in its gift of tremendous power that has been terribly abused; but for the wise use of this power we need more, not less, of the objective dispassionate scientific spirit. For our philosophical purposes we need more of its integrity and its basic humility, its respect at once for the fact and the mystery."

Another informative passage:

"In short the Greeks were cribbed and cabined by their ideal of excellence...they lived in a tidy Euclidean world, finite, static, complete. They had no feeling for horizons, prospects or backgrounds, [having] such a horror of infinity that the idea was taboo...their colonies clung to the Mediterranean...Their ideal of excellence was a design for living in this small world, and included elements unsuited to our life as the Greek cornices on our early skyscrapers...In particular the city-state was a very small affair, whose administrative problems were negligible...We have not only created great nations but sought to enable the whole population to participate in the whole life of the nation. Now we have set up the idea of a United Nations...We are dealing with problems the Greeks hardly thought of."

And part of a review of one of his later books:

"[Muller argues that] the literary resentment of science is based on the belief that science conceives a universe of brute fact in which the sole principle of explanation is mechanism, in which the conception of human free will is impossible, in which mind is but the passive recorder of events and—perhaps most important of all—in which “values” have no validity. The literary philosophers conceive the alternative to scientific naturalism to be some form of religion, although in practice this is usually no more than a religiosity which takes its chief impulse from the ingrained, unconscious pragmatism of the “believer”—he needs a faith and will have it, for it does him good. At first glance, this literary hostility to science seems the continuation of a crisis in culture which began early in the nineteenth century. In actual fact, however, it is merely the vestige of that historical situation, ritualistically continued and maintaining the appearance of life by feeding on ignorance: Mr. Muller is polite but blunt in saying that literary men of philosophic bent know little about science. What they so courageously defy is the science of Tennyson’s “The Two Voices,” not science now in use."

That review excerpt is from this source.

Weekend Work

A busy weekend building the actual flying machine -- no more simulators! -- with team member Ben Wilson. Feels great to be getting ready to fly!

In the photo, Ben is contemplates the framework, and we stand in the gondola frame with two (of four) fuel tanks. Ben has been with the project ince 2013 and has work the pressurize suit for some 22 hours in many tests.

New Evolution Book In Production

I am working on my forthcoming, graduate-level technical book, 'Principles of Space Anthropology: Establishing a Science of Human Space Settlement" (Springer 2018). This book will introduce space-settlement planners to the evolutionary process, and all that it has to to teach us about the large (and I think inevitable) settlement of places beyond Earth. Here is a quotation from the preface:

"Space settlement will require novel biological and cultural adaptations to support populations of humans, on multigenerational timescales, in environments so far unfamiliar to our species even after 100,000 years of human cultural and biological adaptation to myriad Earth environments. The new field of anthropology that studies such adaptive efforts is space anthropology or exoanthropology, exo- referring to 'beyond Earth', in the same way it is used in the term 'exobiology'."

You can read the larger text of the preface, if you're still interested, posted on Paul Gilster's Cebtauri Dreams site.

HERA Simulated 30-Day Asteroid Intercept Mission

NASA's HERA project is a simulation of a 30-day space flight; my buddy, Air Force aviator Casey Stedman, is aboard, and reporting here. From his blog:

"Continuing my goals of playing a role in human spaceflight, I recently applied to and was accepted as a participant in the Human Exploration Research Analog (HERA) campaign.

HERA is a “high-fidelity research venue for scientists to use in addressing risks and gaps associated with human performance during spaceflight.”...It is a project operated by NASA’s Human Research Program, or HRP, located at Johnson Space Center in Houston, Texas.

Like my experience in the HI-SEAS analog...I will be serving as a subject for NASA’s investigation into mitigating the risks of future space missions. As a “stand-in” for an astronaut, I will be simulating the duties and tasks necessary to conduct a long-duration spaceflight. Whereas in HI-SEAS the mission was one of Martian exploration, this time I will be simulating the launch and flight to a nearby asteroid.

After a several decades of learning to live and operate in Low Earth Orbit (LEO) using the Skylab, Space Shuttle, and International Space Station, NASA is beginning to plan for deep space exploration missions again. There are a number of mission concepts and targets proposed, with all choices eventually leading up to human landings on the planet Mars. But before a rocket carrying astronauts can reach the red planet a number of milestones need to [be] met."

Three More Exoplanets

By my buddy, Paul Gilster, author of the fantastic 'Centauri Dreams: Imagining and Planning Interstellar Exploration':

"About forty light years from Earth in the constellation Aquarius is the star designated 2MASS J23062928-0502285, which as of today qualifies as perhaps the most interesting ultracool dwarf we’ve yet found. What we learn in a new paper in Nature is that the star, also known as TRAPPIST-1 after the European Southern Observatory’s TRAPPIST telescope at La Silla, is orbited by three planets that are roughly the size of the Earth. We may have a world of astrobiological interest — and conceivably several — orbiting this tiny, faint star."

"But bear in mind that at least the inner two planets are probably tidally locked, with one side perpetually facing the star, the other turned away from it. Hence there may be regions near the terminator that receive daylight but maintain relatively cool temperatures. Given that the third planet may turn out to be entirely within the habitable zone, we have a fascinating test case for upcoming attempts to characterize the atmospheres of each of these Earth-sized worlds."
