As we continue to develop and settle space, accidents and medical emergencies will happen. Soon or later, someone will need to do surgery in space.

Equipment and procedures for surgery in zero and reduced gravity have yet to be developed and tested (a fact that’s often overlooked by advocates of manned deep-space missions), but some work has been done in this field.

Dr. James Burgess, a neurosurgeon at Allegheny General Hospital in Pittsburgh and an adjunct faculty member at Carnegie Mellon University, has invented one such device. The Aqueous Immersion Surgical System is a transparent plastic box that can placed over a wound and pumped full of saline solution. Carefully designed openings keep fluid in while allowing access for for surgical tools. The saline solution is pressurized and controlled to reduce blood loss, which will be critical on space missions where blood for transfusions is limited or unavailable.

AISS is being developed by a team of biomedical engineers and doctors from CMU and the University of Louisville. Prototypes will be tested on four flights of NASA’s C-9 microgravity aircraft on October 2–5. Additional microgravity flights are planned over the next three years. If the tests are successful, AISS may then be tested on a suborbital flight, according to Dr. George Pantalos, professor of surgery and biomedical engineering at the University of Louisville.

The nature of surgical experiments requires hands-on access by the surgeon. This is another example of an experiment that can be performed on reusable suborbital spacecraft which cannot be performed on sounding rockets. The development of a robust commercial suborbital spaceflight may, therefore, be a crucial enabler for safe and effective deep-space exploration.

NASA James Webb Space Telescope
We were having lunch with an astronomer the other day when the subject of the James Webb Space Telescope came up. Somewhat to our surprise, he was not particularly interested in the JWST. Nor was his lack of interest simply due to the instrument’s enormous cost and uncertain schedule. He was much more excited more excited about the new PLANETS telescope being built in Hawaii.

Author J. K. Rowling claims that she turned down a chance to go into space. An article in the Independent, an Irish newspaper, quotes Rowling as saying, “I was offered a seat. For a mere £2 million I could have been on the shuttle, but I turned it down.”

This story belongs in the fiction section with Harry Potter.

NBC News analyst James Oberg reports that Russian cosmonauts are unhappy with accommodations aboard the International Space Station. The complaints surfaced during a post-flight press conference by cosmonaut Gennady Padalka on September 21.

The Russian segment of ISS provides each cosmonaut with about 1/7 as much living space as the American segment, according to the report. Padalka also stated that the Russian segment is cold and noisy, according to Oberg, and compared it to a tiny Krushchev-era apartment or khrushchevka.

Padalka also complained about aging equipment, which hasn’t been updated “in the 20 years since the foundation of the new Russia.”

The housing accommodations are of concern to citizen space explorers visiting ISS. Citizen explorers who travel to the station via Soyuz stay in the Russian segment. Living conditions are undoubtedly acceptable to short-term visitors, who have not complained in the past, but there may be other effects.

Padalka stated that extended one-year stays aboard ISS are unacceptable without major improvements to the Russian accommodations. One-year stays have been proposed in order to free up seats in Soyuz capsules for citizen explorers such as Sarah Brightman. If the cosmonauts revolt, Roskosmos may need to change its plans. If that happens, there may be no more Soyuz flights for citizen explorers.

The situation will become more complicated in a few years when American companies such as SpaceX, Boeing, and Sierra Nevada begin carrying NASA crew and citizen explorers to the space station. Those explorers will presumably stay in the American segment, although details have not been worked out yet. (Or if they have, they have not been made public.)

This points to the need for new facilities in orbit, such as the private space stations Bigelow Aerospace is working on. If those facilities are slow to emerge, the development of citizen space exploration in low Earth orbit may be hindered. Fortunately, a flourishing suborbital spaceflight industry will exist by that time and, unlike the orbital tourism industry, it will not be limited to multimillionaires.

“There’s a new word now for that old-school vision of California, and that word is – Texas!” Bill Whittle produced the following video about California’s economic problems and XCOR’s move to Texas.

California needs companies like XCOR a lot more than the companies need California, but the state does not seem to realize that. California’s denial mirrors many of the statements we hear from politicians in DC about commercial space. Like the government of California, they think private enterprise needs the government (in this case NASA) more than the government needs private enterprise.

Masten Space Systems has released the following statement on the loss of the Xaero vehicle during flight test on September 11.

Last week we encountered a sub system failure in flight that necessitated turning the rocket off while still in the air. Landing at that point winds up considerably rearranging the rocket into rocket parts.

Consumer Reports has found that modern Pyrex glassware is less resistant to thermal shock than Pyrex which was made years ago. This is due to changes in the type of glass used to make Pyrex.

This mundane example reflects the problems engineers face when trying to recreate old systems. Components and materials that were used in the original design may no longer be available, and if they are still being manufactured, the new items may not be functionally identical to the original. That’s why it isn’t feasible to rebuild the Saturn V today, as some nostalgic space buffs have suggested. It’s not because NASA has lost the blueprints – that’s an urban legend – but because the supply chain for critical components no longer exists.

We attended the 100 Year Starship Symposium mostly out of curiosity. There’s not a lot of commonality between 100 Year Starship and Citizens in Space. We focus on making low-end, near-term applications of human spaceflight available to the average citizen. 100 Year Starship, on the other hand, is about as high-end and long-term as you can get. Still, we were curious to see how the 100 Year Starship organization was planning to approach such an audacious challenge.

The Discovery Channel has done a lot to make the public aware of the dangers of asteroid impacts, through numerous documentaries. Discovery Communications, which owns the Discovery Channel, is doing more than just scaremongering, though. Discovery has partnered with Lowell Observatory to build the 170-inch Discovery Channel Telescope, which saw first light in April of this year.

The Discovery Channel Telescope will spend part of its time looking for potentially dangerous near-Earth objects. It won’t be hunting alone, though. Planetary Resources and the B612 Foundation are planning space-based telescopes to search for near-Earth asteroids. It’s good to see so the private sector stepping up to the plate on this, since politicians have shown so little interest.

"Dressing For Altitude: US Aviation Pressure Suits from Wiley Post to the Space Shuttle" book cover

Dressing for altitude is a technical history that covers US pressure suits from the 1930’s up through the Space Shuttle program. The focus is on “aviation” pressure suits, so the book does not cover the Gemini and Apollo spacesuits, or the Shuttle EVA suit, which are covered well in other publications. It does, however, include the Mercury spacesuit, which was derived from a US Navy aviator’s pressure suit. The Shuttle launch and entry suits are, of course, covered.

This book will be of interest to anyone who’s concerned with commercial spaceflight safety. The ebook is available for free download from NASA.

Astronauts have lived and trained in Texas for 50 years, but no astronaut has ever flown into space from Texas. That will change in the next few years when XCOR Aerospace begins flights from a new spaceport in Midland, Texas.

Maureen Adams, a teacher and principal at West Ward Elementary School in Killeen, hopes to be among the first Lone Star astronauts.

Citizen Astronaut candidate Maureen Adams

Adams is an astronaut candidate who is part of Citizens in Space, a project of the United States Rocket Academy which has purchased 10 flights on the Lynx suborbital spacecraft (currently being developed in Mojave, California by XCOR Aerospace). Citizens in Space has already chosen its first four astronaut candidates, three of whom are from Texas: Maureen Adams and two others to be named later this year.

“It’s too soon to say where the flights will launch from,” Adams said. “It could be Mojave, Midland, Florida, or even Curacao. I’m hoping for Texas.”

XCOR expects Lynx test flights to begin early next year and continue for about a year before commercial operations begin. Citizens in Space will fly soon after that. “We’re expecting that our first flights will be in early 2014,” Adams.

Adams has already proven she has the right stuff in a training program that includes high-g and zero-g aircraft flights, unpowered landings, and flight simulators. She was chosen as a citizen astronaut candidate in July 2009. At that time, the program was known as Teachers in Space. In 2011, Teachers in Space became Citizens in Space.

“We’ve broadened our focus to be more inclusive,” Adams said. “Our program will include informal educators, university students, and hobbyists, as well as teachers.

“We also have a new emphasis on citizen science. One of the complaints about Teachers in Space was that people didn’t know what the teachers would be doing during their flights.

“This isn’t just a joyride. Each of our flights will carry 10 to 12 citizen-science experiments. We’ll be operating experiments, working with researchers, and gathering new knowledge in areas of space science that have not been full explored.”

Adams emphasized the difference between citizen science and textbook experiments commonly performed in school classrooms. “These will be true experiments, not mere demonstrations of known principles. Citizen science is asking questions where the answers are not known.”

One of the experiments Adams may operate is a High Altitude Astrobiology investigation designed to capture microorganisms living at the edge of space. “Biologists have discovered there are living organisms at altitudes up to 100,000 feet or more, but we don’t have a good way to collect those organisms at present. Developing such a system is important for global epidemiology, bioprospecting, and other disciplines. That’s the sort of cutting-edge research we’ll be involved in.”

Other experiments may involve fluid physics, materials science, remote sensing, and astronomy.

“Students need to see teachers doing real scientific research,” Adams said, “And teachers need experience with real research so they can accurately teach the process to students.”

Masten Space Systems has posted a blog entry about today’s test flight, which didn’t go as well as planned.

Today, Masten Space Systems conducted a flight test of Xaero to 1 km altitude with the intention of testing flight controls at higher ascent and descent velocities. Our test objectives were met and initial results show the vehicle performed better than expected at altitude. However, the vehicle was lost during final approach to landing, and the initial cause appears to be a throttle valve failure. The most important thing is that our team is safe and with the data from this test, we expect to be flying again soon!

Thanks for your support!

That’s why they call it testing.

Spaceweather.com reports an explosion on Jupiter, which was detected by two amateur astronomers.

According to Spaceweather.com, the event occurred at 11:35 Universal Time on September 10. Dan Peterson of Racine, Wisconsin, observing through a 12-inch Meade telescope, observed a white flash lasting for 1.5-2 seconds. George Hall of Dallas, Texas was capturing a video of Jupiter at the time, which also captured the event.

It’s believed that the explosion was due to a comet or small asteroid collision. Similar events were observed in the past, in June and August 2010. These events underscore the continuing importance of amateur astronomy, as well as the need to discover potential impactors that could hit our own planet.

Safe, affordable pressure suits are a critical, enabling technology for commercial spaceflight. Cost reductions are especially important for suborbital spaceflight, where the ticket prices will be about an order of magnitude lower.

Some progress has been made in this area. Orbital Outfitters and the David Clark Company have produced prototype suits for suborbital spaceflight. A new company, Final Frontier Design, recently unveiled its prototype and even held a successful Kickstarter campaign.

This progress, while promising, is not sufficient. David Clark has a great of experience building pressure suits for NASA and the military, dating all the way back to the Bell X-1, but has never delivered a commercial spacesuit. (The company does have a great deal of experience delivering commercial products in other areas, however, especially its highly successful aviation headsets.) The other companies are startups, with a strong commercial orientation, but have not yet delivered a suit that’s actually flown in space.

A healthy industry needs to have multiplier suppliers for critical components like spacesuits. A single source would lead to monopoly pricing and leave the industry vulnerable to single-point failures due to a natural disaster, product recall, or business failure. Two suppliers are better, but a single failure would still put the industry right back in a monopoly situation. For the long-term health of the industry, at least three viable suppliers are preferable.

Right now, most impartial observers would put the number of proven suppliers at about one and a half.

One way to address this problem is a prize for low-cost spacesuit development.
