A NASA shuttle program manager recently proposed a new plan which would allow NASA to cut costs on moon travel. The plan revolves around a "shuttleless shuttle" concept that has been around NASA for years, but adds in a few new components.

Since even before the recession, people have continuously searched for opportunities to save money. Hunting for grocery coupons and exercising haggling skills stand as best practices in the lives of many. Tuesday, another approach at cutting costs was announced through the Associated Press; this attempt targeted the price tag on moon travel. 

John Shannon, NASA's shuttle program manager, recently presented a plan for cost-saving moon travel, known as the Shuttle-Derived Heavy Lift Launch Vehicle, to an independent panel. The panel, which holds responsibility for reviewing NASA’s expensive space travel plans, reacted positively to Shannon’s proposal.  

According to the Associated Press, Shannon’s plan revolves around a concept that has been around NASA for decades: the shuttleless shuttle. Under NASA’s permission, Shannon has been informally toying with this concept with a group of others over the last three years.

The model Shannon proposes would be comprised of the old space shuttle system, equipped with its large orange fuel tank and twin solid-rocket boosters, only with no shuttle. Instead, the rocket would have two items sitting on the external fuel tank: a generic cargo container, which would be the only new component, and an Apollo-like capsule, which would be located inside the cargo carrier and allow for astronaut travel. The capsule in this model would be the same as the new Orion crew capsule being designed for Constellation, NASA’s new moon program.

The cost-cutting model calls for hardware that already exists, which would save both time and money.   For example, if NASA were to move forward with the plan, they would not have to reconfigure the Kennedy Space Center launch site and use shuttle flight control systems, according to Shannon.

“The new system could also launch a year earlier, and fewer space workers would have to be laid off because of that,” Shannon said.

Although the proposed design is not as powerful as current designs, the new shuttle would still enable two astronauts to travel at one time to either the moon or the international space station. (Current architecture can hold around three to four astronauts.)

NASA is currently on course with a 4-year-old plan which costs $35 billion and is aimed at both constructing new rockets and sending astronauts to the moon over years to come. Shannon’s proposal provides an alternative to this plan and would cost roughly $6.6 billion.

Shannon’s plan does not stand as the only one of its kind. One panel chairman and longtime aerospace executive, Norman Augustine, mentioned liking a similar proposal from approximately 20 years ago.

Additionally, Michael Curie, a NASA spokesman, said that Shannon was encouraged to present in the spirit of sharing the options NASA has studied in the past.

Curie assured that Shannon's presentation does not reflect a lack of backing toward current NASA plans: "NASA believes the best plan is to fully fund the current architecture... This does not indicate a lack of confidence in or support for the current program," he said.

According to space experts, however, the plan illustrates that top officials in NASA do have concern regarding their chosen moon travel plan. As the Associated Press reports, experts are convinced that the panel’s reaction, along with the upper-level management’s fingerprints on Shannon’s proposal, suggest that NASA management may be shifting gears, or at minimum, signaling doubts regarding the more expensive plan.

Keith Cowing, a former NASA engineer who heads the Nasawatch.com web site, explained, "It clearly reflects some doubts among senior agency folks in the overall veracity of their current approach."

While all of this is occurring, the whole program of human spaceflight has been undergoing evaluations from an outside board, due to President Barack Obama’s science policy.

The one thing that irks me about today's space "exploration" is the massive risk concern. Guess what guys, it's the final frontier: there is going to be unimaginable risk. How did we get to the moon so quickly? By going for it full throttle, and not waiting around for endless red tape. Every astronaut I've heard or read about has said that they didn't mind the risks, they just wanted to get out there. I don't think they told Columbus that he couldn't go off to an unknown land with only a few ships. I don't think they told Polo that it was too risky to go chat with the Mongols. I don't think Erik the Red was chided for trying to expand Viking settlement.

In short, all great explorations have happened, and will continue to happen, with great risk. One can only reduce risk by reducing the unknown. However, the entire point of exploration is to make the unknown known.

Final question: Why, exactly, is the same risk amount allowed fifty years ago so much higher than that allowed today? Personally, I'm pretty sure the '40s-'60s accomplished far more significant things than we have today (stopping Nazis, building the bomb, going to the moon, etc).

Because these days we falsely believe that human lives are priceless. We also believe that progress at the expense of human lives is bad. Back in the 40's, 50's, 60's we wanted to be the best we didn't give a damn if the possibility of failure and certain death were 10%, we have a 90% chance of pulling it off and being the best. Now, we are a culture of wimps unwilling to take risks and unwilling to do all that is necessary to conquer the next milestone.

The difference then is we were afraid of the Soviets having a massive advantage where they could kill us all. With WW2 and the Japanese/Germans fresh in everyones mind still, and the terrible consequences of allowing another country to do that were well known. This motivated the USA to push forward with our space program and military programs at break neck pace to ensure we could match or beat any capability the Soviets had. After the cold war however, the national desire to do that soon wore off and we were back to the ultra pansy mindset of we're the best, let's kick back and enjoy it. With China now pushing ahead currently the way we were back in the 50's I'm somewhat surprised that we aren't as a nation getting motivated once again. It will eventually happen, but probably not until we end up in a conflict with China and they inflict considerable damage on us.
