To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts:

1. Legal Standing. 2. Safety Awareness. 3. Economic Viability. 4. Theoretical-Empirical Relationship. 5. Technological Feasibility.

In this post I will explore Economic Viability. I have proposed the Interstellar Challenge Matrix (ICM) to guide us through the issues so that we can arrive at interstellar travel sooner, rather than later. Let us review the costs estimates of the various star drives just to reach the velocity of 0.1c, as detailed in previous blog posts:

Interstellar Challenge Matrix (Partial Matrix)

Propulsion Mechanism Legal? Costs Estimates
Conventional Fuel Rockets: Yes Greater than US$1.19E+14
Antimatter Propulsion: Do Not Know. Between US$1.25E+20 and US$6.25E+21
Atomic Bomb Pulse Detonation: Illegal. This technology was illegal as of 1963 per Partial Test Ban Treaty Between $2.6E12 and $25.6E12 . These are Project Orion original costs converted back to 2012 dollar. Requires anywhere between 300,000 and 30,000,000 bombs!!
Time Travel: Do Not Know. Requires Exotic Matter, therefore greater than antimatter propulsion costs of US$1.25E+20
Quantum Foam Based Propulsion: Do Not Know. Requires Exotic Matter, therefore greater than antimatter propulsion costs of US$1.25E+20
Small Black Hole Propulsion: Most Probably Illegal in the Future Using CERN to estimate. At least US$9E+9 per annual budget. CERN was founded 58 years ago in 1954. Therefore a guestimate of the total expenditure required to reach its current technological standing is US$1.4E11.

Note Atomic Bomb numbers were updated on 10/18/2012 after Robert Steinhaus commented that costs estimates “are excessively high and unrealistic”. I researched the topic and found Project Orion details the costs, of $2.6E12 to $25.6E12, which are worse than my estimates.

These costs are humongous. The Everly Brothers said it the best.

Let’s step back and ask ourselves the question, is this the tool kit we have to achieve interstellar travel? Are we serious? Is this why DARPA — the organization that funds many strange projects — said it will take more than a 100 years? Are we not interested in doing something sooner? What happened to the spirit of the Kline Directive?

From a space exploration perspective economic viability is a strange criterion. It is not physics, neither is it engineering, and until recently, the space exploration community has been government funded to the point where realistic cost accountability is nonexistent.

Don’t get me wrong. This is not about agreeing to a payment scheme and providing the services as contracted. Government contractors have learned to do that very well. It is about standing on your own two feet, on a purely technology driven commercial basis. This is not an accounting problem, and accountants and CFOs cannot solve this. They would have no idea where to start. This is a physics and engineering problem that shows up as an economic viability problem that only physicists and engineers can solve.

The physics, materials, technology and manufacturing capability has evolved so much that companies like Planetary Resources, SpaceX, Orbital Sciences Corp, Virgin Galactic, and the Ad Astra Rocket Company are changing this economic viability equation. This is the spirit of the Kline Directive, to seek out what others would not.

So I ask the question, whom among you physicist and engineers would like to be engaged is this type of endeavor?

But first, let us learn a lesson from history to figure out what it takes. Take for example DARPA funding of the Gallium Arsenide. “One of DARPA’s lesser known accomplishments, semiconductor gallium arsenide received a push from a $600-million computer research program in the mid-1980s. Although more costly than silicon, the material has become central to wireless communications chips in everything from cellphones to satellites, thanks to its high electron mobility, which lets it work at higher frequencies.”

In the 1990s Gallium Arsenide semiconductors were so expensive that “silicon wafers could be considered free”. But before you jump in and say that is where current interstellar propulsion theories are, you need to note one more important factor.

The Gallium Arsenide technology had a parallel commercially proven technology in place, the silicon semiconductor technology. None of our interstellar propulsion technology ideas have anything comparable to a commercially successful parallel technology. (I forgot conventional rockets. Really?) A guesstimate, in today’s dollars, of what it would cost to develop interstellar travel propulsion given that we already had a parallel commercially proven technology, would be $1 billion, and DARPA would be the first in line to attempt this.

Given our theoretical physics and our current technological feasibility, this cost analysis would suggest that we require about 10 major technological innovations, each building on the other, before interstellar travel becomes feasible.

That is a very big step. Almost like reaching out to eternity. No wonder Prof Adam Franks in his July 24, 2012 New York Times Op-Ed, Alone in the Void, wrote “Short of a scientific miracle of the kind that has never occurred, our future history for millenniums will be played out on Earth”.

Therefore, we need to communicate to the theoretical physics community that they need get off the Theory of Everything locomotive and refocus on propulsion physics. In a later blog posting I will complete the Interstellar Challenge Matrix (ICM). Please use it to converse with your physicist colleagues and friends about the need to focus on propulsion physics.

In the spirit of the Kline Directive — bold, explore, seek & change — can we identify the 10 major technological innovations? Wouldn’t that keep you awake at night at the possibility of new unthinkable inventions that will take man where no man has gone before?

PS. I was going to name the Interstellar Challenge Matrix (ICM), the Feasibility Matrix for Interstellar Travel (FMIT), then I realized that it would not catch on at MIT, and decided to stay with ICM.

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts:

1. Legal Standing. 2. Safety Awareness. 3. Economic Viability. 4. Theoretical-Empirical Relationship. 5. Technological Feasibility.

In this post I will explore Safety Awareness.

In the heady rush to propose academically acceptable ideas about new propulsions systems or star drives it is very easy to overlook safety considerations. The eminent cosmologist Carl Sagan said it best “So the problem is not to shield the payload, the problem is to shield the earth” (Planet. Space Sci., pp. 485 – 498, 1963)

It is perfectly acceptable if not warranted to propose these technologically infeasible star drives based on antimatter and exotic matter, as academic exercises because we need to understand what is possible and why. However, we need to inform the public of the safety issues when doing so.

I do not understand how any physicist or propulsion engineer, in his/her right mind, not qualify their academic exercise in antimatter propulsion or star drive with a statement similar to Carl Saga’s. At the very least it gets someone else thinking about those safety problems, and we can arrive at a solution sooner, if one exists.

We note that the distinguished Carl Sagan did not shy away from safety issues. He was mindful of the consequences and is an example of someone pushing the limits of safety awareness in the spirit of the Kline Directive, to explore issues which others would (could?) not.

We have to ask ourselves, how did we regress? From Sagan’s let us consider all ancillary issues, to our current let us ignore all ancillary issues. The inference I am forced to come to is that Carl Sagan was a one-man team, while the rest of us lesser beings need to come together as multi-person teams to stay on track, to achieve interstellar travel.

In interstellar & interplanetary space there are two parts to safety, radiation shielding and projectile shielding. Radiation shielding is about shielding from x-ray and gamma rays. Projectile shielding is about protection from physical damage caused by small particle collisions.

I may be wrong but I haven’t come across anyone even attempting to address either problems. I’ve heard of strategies such as using very strong electric fields or even of using millions of tons of metal shielding but these are not realistic. I’ve even heard of the need to address these issues but nothing more.

Safety is a big issue that has not been addressed. So how are we going to solve this? What do we need to explore that others have not? What do we need to seek that others would not? What do we need to change, that others dare not?

Previous Post in this Debunking Series.

Why is it necessary to debunk bad or unrealistic technologies? If don’t we live in a dream world idealized by theoretical engineering that has no hope of ever becoming financially feasible. What a waste of money, human resources and talent. I’d rather we know now upfront and channel our energies to finding feasible engineering and financial solutions. Wouldn’t you?

We did the math required to figure out the cost of antimatter fuel one would require just to reach 0.1c and then cost at that velocity, never mind about reaching Alpha Centauri.

The table above compiled from various sources shows that the cheapest cost of just reaching 0.1c velocity is of the order of $125,000,000,000,000,000,000. This so unthinkably large even I don’t know how to conceptualize it, and by comparison, conventional rockets appear realistic!

Also note that the large variations in the estimates of the amount of antimatter required combined with the larger variations in the mass of the spacecraft antimatter engines could propel. That is no one reallys has a handle on what this would take.

But wait, let me quote EJ Opik, “Is Interstellar Travel Possible?” Irish Astronomical Journal, Vol 6, page 299.

The exhaust power of the antimatter rocket would equal the solar energy power received by the earth — all in gamma rays (and Opik quotes Carl Sagan, Planet. Space Sci., pp. 485–498, 1963) “So the problem is not to shield the payload, the problem is to shield the earth

I don’t need to say more. Debunked.

Andrew Skolnick drew my attention to this great article by John Eades, a CERN senior scientist, about antimatter engines and weapons.

Antimatter Pseudoscience by John Eades in the Skeptical Inquirer http://www.csicop.org/si/show/antimatter_pseudoscience/

We, Andrew Skolnick and I, did the calculations and showed that it would cost 42,876x our 2011 World GDP to use antimatter as a propulsion fuel to get to Alpha Centauri!!

John Eades goes one better and shows that it is not technologically feasible, ever. His article is facinating reading, and shows that we cannot base our hopes to leave Earth on antimatter drives.
