Various NASA spokespersons, astronauts and directors are seeking a tenfold increase in flight safety standards for future astronauts. Many of these comments are referenced in an article, “NASA Clamors for Safer Launchers”, in Florida Today (November 29, 2009) by Todd Halvorson.
In addition, Wayne Hale, NASA Deputy Administrator for Strategic Partnerships went further speaking to the commercial space industry at the International Symposium for Personal and Commercial Spaceflight, (ISPCS) in October this year, saying most likely NASA would require a crew escape system on any services they contract for in crew transportation.
Due to the launch dynamics, achieving these new safety levels in vertical launch vehicles will be far more difficult than for horizontal launch vehicles. Crew escape from a vertical launch failure imposes the most significant risks, weight penalties and complexities of the escape system. For instance, the Apollo Command Module (CM) carried three crewmen, at a total mass of 6000 kg. The recovery parachutes and equipment to land the CM, amounted to 250 kg or 4.2 % of the CM’s total mass. The Launch Escape System (LES) necessary to lift the CM away from a launch failure weighed 4200 kg. This adds significant weight penalties to the launch vehicle, complexities and costs since the LES is expendable each flight. Just to protect the crew during launch, the vertical launch vehicle must carry the LES, adding weight penalties sixteen times that of the parachutes and recovery systems.
Utilizing aerodynamics in a horizontal launch vehicle eliminates the need of an escape tower (LES), by employing aircraft style flight safety characteristics. The other risks imposed by rocket propulsion, extreme speeds, altitudes and aerodynamic heating during the flight also warrants an escape system as identified by NASA. Current escape technology for aircraft will not meet the requirements for space flight or accommodate multiple individuals. By satisfying these escape needs for a space plane, we can avoid the severe weight penalties associated with escape towers and fly individuals to space in aircraft style safety and efficiency. Vertical launch vehicles are best suited for un-manned operations.
The Aircraft Escape Cabin (AEC) represents the first new escape technology in a decade. The AEC enables crew escape and recovery from supersonic speeds and extreme altitudes. In an emergency, the AEC separates and glides to the most desirable landing site on water or land. Equipped with light weight, simple devices and parachute technology, the AEC provides safe crew recovery from most any in-flight emergency.
The AEC’s modular feature also satisfies military crew survival needs and offers the economics and versatility of interchangeable modular sections. The primary markets for this modular technology are in new space, military operations and flight test vehicles. In addition, flight research is the first expenditure on new aerospace vehicles. Currently, no manned supersonic, high altitude, rocket powered, flight test vehicles are available. Targeting this market satisfies an urgent need and offers a valuable service for the development of new vehicles and propulsion systems.
The simplicity of the AEC technique enables it to be adapted to an existing aircraft. TAAS Company in Georgia, teamed with other aerospace companies, proposes to demonstrate a prototype AEC. Since it is relatively small, without propulsion or landing gear, the projected cost to fabricate and fly the AEC is less than $350,000. The prototype can subsequently be used with a rocket powered flight test vehicle.
High speed and altitude trajectories will change aviation as we know it. World transportation and access shrinks in time from double digits to two hours. Eventually, with additional speed, crew and passengers will be flying in orbit. Flight testing is the most urgent need and for this we need new escape technology.

Is all this space travel worthwhile? Will it really contribute to our civilization or our touchingly naive way of life? Will it even lift our spirits?
I cannot be sure about the first two, as I feel these might be permanently floating somewhere out there. But I have some space-sourced spirit lifting to share.
Japan’s Sapporo Breweries, the entity that brings you those large silver tins of beer to complement your rainbow roll, announced this week that it is launching space beer.
According to Reuters, Sapporo “Space Barley”, with its cute outer-space sparkling starred label, has been created using barley grown on the International Space Station.

An ad rolls before the newcast footage.
Toshiba, the giant electronics manufacturer, had already booked advertising time on television networks in Europe and Japan. Their must-stop-and-watch image commercial would feature an armchair rising from the ground to the edge of space, beautifully shot in high definition. It would be a creative way to market Toshiba’s new line of flat screen televisions. The only thing missing was the “money shot” — an arm chair hovering at the edge of space. Special effects was not an option because viewers would know it was fake. Sort of like the scene of the White House blowing up in the movie Independence Day. Everyone knows it’s not real.
NASA could probably put Toshiba’s little orange armchair in space, but that would take years of planning and cost millions of dollars. And their ad campaign was set to air in just weeks. The production company in charge of creating the ad is based in London, England. But even across the Atlantic Ocean, they had heard of a man who works out of a small warehouse in Rancho Cordova, a man who has flown science projects under helium balloons to the edge of space more than 100 times. When John Powell received the first email asking if he could fly a light-weight chair high above the Earth, his first reaction was “no one is going to be sitting in the chair, right?” Correct. Powell’s second reaction: “Yeah, we can do that. It sounds like a really fun mission.”
