Mars Express Configurations and Unmanned Kick, Coast Start for Nuclear Orion for 1% of Fallout or Less

The explosions for Orion that occur in the magnetosphere where the magnetic field lines lead back to earth is where fallout will come back down and be a problem.

We have already studied that reducing the fission component of any bomb and getting to higher fusion purity greatly reduces fallout and also a north pole launch reduces the fallout that returns to earth. Having a pile of conventional explosives for the first pulse also helps since the ground contact explosion is messier than the air bursts.

It would also seem best to send it up during a snow storm which would contain the fallout that coincides with a solar storm that flattens out the magnetosphere.

If you could not make the pure fusion bombs, which has not been done yet then another way to further reduce the radiation is for an unmanned high-G sprint start to a point outside the magnetosphere zone.

High-G Asteroid Interceptor

An unmanned Orion asteroid interceptor was designed. It would not need shock absorbers. Artillery arming, fusing, firing system for shells are regularly built to take 1000 Gs.

There was a three page paper: Nuclear explosive propelled Interceptor for deflecting objects on collision course with Earth. Johndale Solem, Los Alamos, proposed unmanned vehicle. No shock absorber or shielding. The pulse units were 25kg bombs of 2.5 kiloton yield.

Get to high velocities with only a few explosives and small shock absorbers or no shocks at all. Launch against a 100 meter chondritic asteroid coming at 25 km/sec. 1000 megatons if it hits. Launch when it is 15 million kilometers away and try to cause 10000km deflection. A minimal Orion weighing 3.3 tons with no warhead would do the job. 115 charges with a total of 288 kiloton yield. Launch to intercept in 5 hours. Ample time to launch a second if the first failed.

Sprinting out of the Magnetosphere
Notice the unmanned high acceleration configurations would reduce the number of charges to go through the atmosphere to about 1-3 charges. Instead of 200 charges to go to orbit with constant lower acceleration. Kick it hard with 3 or fewer 100G force acceleration charges. (charges would go off every half second for fast acceleration instead of 1.1 seconds for human safe acceleration).

It can head up at 100Gs. 980 m/s**2. So only 1-3 charges is enough to give escape velocity then coast. It is only a matter of containing the fallout from 1-3 low level charges. Plus 1-3 charges and that is it we have tens of thousands to millions of tons to start the space age.

Some of the Orion configurations were for 1000Gs of acceleration. At 100G’s in 10 seconds it would be almost 50 kilometers up. 20 shots assuming one every 0.5 second. In 20 seconds it would be almost 200 kilometers up.

Some more charges could be used to slow the Orion for a rendezvous with human passengers and acceleration sensitive cargo. They could then fly anywhere in the solar system at a leisurely pace without concern about fallout.

Mars Express
Another aspect of the fast acceleration that is possible is that an unmanned Orion go from earth or earth orbit to Mars (decelerate at halfway) and get to Mars in under one day going at 100Gs if Mars and Earth are in the close approach. If the unmanned version was going at 1000Gs (which was a design that is possible), then Earth to Mars could be done in a few hours. At about 300Gs and you would be looking at a Mars Overnight package delivery.

Mars comes to about 50 million kilometers (36 million miles) of Earth on close orbital approach. This is just over three times the asteroid intercept scenario.

It is possible to get fit people to safely endure 30gs for one minute.

High acceleration compensation.

Equally important are some experimental protective techniques for increasing +Gz tolerance, currently under investigation. These methods include :

Pulsating G suits, synchronized to the electrocardiogram. This technique would provide a pulse superimposed on the systolic pulse, producing a higher systolic pressure at head level.

Optimization of physical fitness training procedures. This may allow a more forceful straining manoeuver with less fatigue.

Drugs to increase head level blood pressure on a short-term basis.

A liquid immersed and liquid breathing (special oxygen supplying liquid) person could sustain 15-80Gs. All air voids would need to have liquid. Ears, lungs etc… The liquid immersion and liquid breathing method has not been developed yet, but could work in theory and would increase the sustained acceleration tolerance to some higher level.

You are correct; 6-month confidentialty is the norm. Suzanne must be a newbie.

Suzanne,

I did state that there is an average decline in well production from the initial rates. It is mentioned in about the 7th paragraph (so near the top). Plus it has a link to an entire article talking about decline rates for the Bakken. I do not see why you think initial production rates is misleading. The terms clearly indicate "here is what this thing is starting out" there would be no need for the term if "this is what starts at and it will stay the same".

In terms of the 6 month confidentiality. All companies take time to submit their financial information to regulators or state agencies. The 6 month period of confidentiality does not seem unusual to me.

I think that gold mines, diamond mines would have similar periods.

It would allow a company to still acquire nearby properties during that time.

A provisional patent filing gets 1 year from the time of filing before the information is made public. They also have that one year time to file a full patent.

"Initial rates" or "came on at" or "initial production" are very misleading terms. I know for a fact that several wells in the Bakken that have come on at high rates, between 2000 and 3000 have dropped off immediately to around 800-1000...sad when oil and gas guys are no better than used car salesmen to get investors all pumped up. And in ND since they can request confidentiality, we don't know the extent of the drop off until 6 months later. I'd never put my money in any company that "needs" confidentiality.

If Enron told me my hair was on fire, I might well wait to smell smoke before I reached for a bucket. I question the accuracy of the Enron Oil and Gas reports because I've seen how rife with fraud their reports in other energy fields are. I am insufficiently familiar with how EOG could be salting these reports to make specific accusations, but the disproportionately productive finds by EOG concern me.

Nevertheless, running in terror from the great demon "Peak Oil" does seem a bit excessive. If you have the coin to get off the grid, more power to you, so to speak. I just hope the energy pricing bubble we're in lasts long enough to capitalize more exploration and development of resources in the US.

We might even pressure Congress to get real, but that seems less of a risk than the "Peak Oil" demon fantasies.

On the first map, the county shown as Oliver is Mercer!

I disagree. The information in hundreds of posts under the energy heading explain why.

There would be a global peak in oil and related liquids when production falls consistently but we are making new highs in terms of more production. My mega oil projects article shows what production I expect to come online.

Demand growth has been higher than supply, but that is not peak oil.

If you want to comment more then read my energy articles first or at least my oil and oilsand articles.

Hmm...this won't help to offset Peak Oil, you know that right? I mean Peak Oil is here already. Nothing can save us, or preserve our way of life. You should get off the grid while ytou still can. I've been off the grid for 8 months now. I'm prepared. ONce the powerdown occurs.....technology goes right our the window. Become a survivor, not part of the dieoff.
