NILFiR

Jumpboy11j:

NILFiR stands for Neutron Induced Lithium Fission Reaction. So far as I know, I am the first to think of the potential that this reaction has in power generation (though I will retract this claim if anyone finds a citation for something earlier than March 3, 2008 on this topic). The reaction itself releases 16 MeV. Though not yet tested, this reaction looks very promising for power generation the world over, not least because it cannot possibly be used in a nuclear bomb. The reaction would most likely be in the liquid phase, with a mixture of pure elemental Lithium and Beryllium in a carefully controlled ratio. The reactor would involve fairly similar technology to a Molten Salt reactor.

==The Reaction==

Li-7+n->Li-8->Be-8->2 He-4

The reaction is caused by Lithium-7 absorbing a Neutron. This creates Lithium-8, which has a half life of about 838 milliseconds. This is one out of 2 reasons why this reaction could not be used in a nuclear bomb: 838 seconds after a uranium nuclear bomb goes off, it has already long exploded. This would mean that a nuclear bomb based on NILFiR would "fizzle" and prevent any serious detonation. The other reason is that the Beryllium involved in neutron production would take a significant amount of time, on the scales of a nuclear explosion, to generate neutrons.

The energy is released primarily in the reaction Li-8->Be-8. This is a beta decay reaction. It releases the 16 MeV in 2 forms: 13 MeV of it in a very high energy electron, and 3 MeV of it in a neutrino. The neutrino will in essentially all cases be lost to the rest of the universe without interacting with anything else. That leaves 13 MeV (technically, 12.9645 MeV. Close enough.). 90 further KeV are released in the reaction Be-8->2 He-4. However, in comparison to the amount of energy released through other means, this is very much negligible. It is enough energy to make the 13 MeV figure accurate, though.

===Radioisotopes===

In terms of radioactive isotopes, none are inherently created in this reaction. All light elements are involved, and any radioisotopes released in this reaction will decay to negligible levels literally within one minute of being in the reactor. The reactor vessel, however, is another matter. A neutron flux will inevitably lead to some level of radioactivity in the reactor vessel. However, this will be radiation of a more low level and would not pose a very serious risk to public health, provided that it is disposed of carefully. There is one instance in which the production of radioisotopes becomes possible, but I will expand upon that later.

It is possible that Beryllium-10 could be produced as a result of Beryllium-9 in the reactor absorbing a neutron. This will happen in a fairly small fraction of cases. At the optimal Be:Li ratio for neutron production of 1.68, 22% of neutrons will be absorbed by Beryllium instead of Lithium. It is also possible that fast neutrons, which are an intermediate in neutron production, could be absorbed by the Lithium nucleus, which would cause the release of a tritium nucleus.

Neither of these two isotopes are extremely dangerous. They both decay via beta decay. Beryllium-10 has a half life of 1.5 million years, and Tritium 12 years. A relatively small amount of shielding will keep both well contained.

==Neutron Production==

Next up is the reaction for neutron production. Pure lithium, when bombarded with low energy neutron, will generate 1 high-energy electron and 2 moderate-energy Helium-4 nuclei. Pure Lithium will not generate neutrons to make this a self-sustaining chain reaction unless some mechanism is added to create the neutrons. However (and this is important, and it seems, fairly often confused), by the addition of Beryllium to the Lithium, the high energy particles can cause the Beryllium nucleus to split. The reaction is:

Be-9-> 2He-4+n

This reaction absorbs, by my calculations, 1.67 MeV. I got this by subtracting the mass of a Beryllium atom from the mass of 2 Helium-4 atoms and a neutron. This is in approximate agreement with the number given on Wikipedia of 1.6 MeV per reaction. Since my number is higher and more precise, I am inclined to go with it. instead. This energy is obtained by a collision with a fission fragment with a high energy. These collisions can happen until the fission fragments have energies below 1.67 MeV, at which point neutron production from that particular reaction stops. By my calculations, when the Be:Li ratio (by number of atoms, not by mass) is 2:1, 3.64 neutrons will be produced per fission. However, a certain

NILFiR stands for Neutron Induced Lithium FIssion Reaction

This is the reaction:

Li-7 + N => Li-8

Li-8 => Be-8 + 16 MeV

Be-8 => 2 He-4 + 90 KeV.

The total energy gain is ~16.1 MeV. The energy density is about 2 MeV/AMU (193 trillion joules/ Kg) more than twice Uranium.

Now all of this so far is great, but you would need an expensive and power hungry external neutron source because this reaction doesn't produce any neutrons.

This is how I would alleviate this:

Deuterium contains a proton and a neutron. The binding energy per nucleon is about 1.25 MeV. That meant that to split it, and create a proton and a neutron, you need 2.5 MeV (actually 2.45, but close enough). The fission products (2 alpha particles) have 8 MeV each, so a collision with deuterium will be enough to split it. If bound up in LiD (Lithium Deuteride), I would think that about 3 neutrons per fission would be generated, although I have no real idea. Another possible way to generate neutrons is Beryllium. An alloy of lithium and beryllium would stay solid at higher temperatures and need less energy per neutron.

The cross section for the reaction is small, .05 Barns, but the high neutron yield per mass, and the fact that the lithium atom is small to begin with, should keep the critical mass small. It will also help that D is a neutron moderator. Another positive is that the most radioactive thing this reaction can POSSIBLY create is tritium, which isn't that bad.

Hab Consumable Masses in Mars Direct

2010-03-23T20:04:07Z

Jumpboy11j: /* References */

This is the page for estimating the masses of consumables in Mars Direct as part of the Tsiolkovsky Compendium Project. On page 92 of his book [[The Case For Mars]], Zubrin estimates them to be as follows:

*Consumables: 7.0 Tonnes consisting of (TCFM page 92):
**Oxygen: 160 kg total (1 kg/man*day at 80% reuse)
**Dry Food: 1600 kg total (.5 kg/man*day at 0% reuse)
**Whole Food: 3200 kg total (1 kg/man*day at 0% reuse)
**Potable Water: 0 kg total [?] (4 kg/man*day at 80% reuse)
**Wash Water: 2080 kg total (26 kg/man*day at 90% reuse)

=Oxygen=

==Consumption Rate==

On the space shuttle, Oxygen is used at a rate of .8 kg per person*day [3]. Zubrin's 1 kg per day seems reasonable, especially considering that astronauts will be using this Oxygen at a high rate. This reference [1] suggests that under a high metabolic load, such as that will probably exist for astronauts doing work on Mars, .96 kg per day is more reasonable. 1 kg per day is a good starting point considering margin necessities and losses.

==Reuse Rate==

Based on technologies pioneered on the ISS, 90-95% closure for oxygen seems reasonable [citation needed]. Assuming the lower number, that is 0.1 kg per day of oxygen. Over 600 days with 4 people, that is 240 kg. With 95% closure, that is 120 kg of oxygen. An intermediate value falls at 180 kg, right near Zubrin's 160 kg.

==Total Mass for 600 day Mission==

Based on the above, a figure of 180 kg of Oxygen is a reasonable estimate.

=Dry Food=
==Consumption Rate==

On the ISS, each crewmember needs 1.77 kg per day of dried food [2].

==Reuse rate==

Zubrin assumes a 0% reuse rate for food. This basically assumes no regeneration of food, and since food is basically not regenerated on any system, there is no reason this should change unless significant farming is to be implemented. In the opinion of the writer ([[user:jumpboy11j|Jumpboy11j]]), farming would be experimental as opposed to a staple in the mission, and for this reason it is unwise to count on farming to provide a significant part of the food allowance.

==Total Mass for 600 day Mission==

1.77 kilograms per day over 600 days is a total of 1,062 kg per person over the course of the mission. With the standard 4 person Mars Direct crew, that is a total mass of 4,248 kg of food. Zubrin uses the much lower estimate of just 1,000 kg total based off .5 kg per day. However Zubrin also includes whole (non-dehydrated) food in his launch manifest, which presumably makes up the difference (see the discussion of whole food below).

Based on the minimum possible energy content for totally dry food of 4 calories per gram, and a daily calorie intake of 2,500 calories, which is on the high side if the crew is mixed-gender [http://www.fatfreekitchen.com/weightloss/weightloss.html], each crewmember will need .625 kg/day of food. Since the food will also contain significant amounts of fats and proteins which have a higher specific energy, .5 kg/person per day for totally dehydrated food is theoretically possible. However, 1.77 kg per person*day is more realistic given that is what is used in real life.

=Whole Food=

== Consumption Rate ==

Reference [2] does not mention whole food, so presumably none is consumed on the ISS. However resupply missions do bring whole food with them to boost morale, so presumably we should be able to find some numbers.

== Reuse Rate ==

Not relevant (see discussion of dry food).

== Total Mass for 600 day Mission ==

One ISS crew member consumes in one day 1.77 kg of dry food (with 0.8 kg of water to hydrate it), and 1.62 kg of drinking water. One Mars Direct crew member consumes in one day 0.5 kg dried food, 1.0 kg of whole food, and 4.0 kg of drinking water.

If the same water/dried food mass ratios are used for Mars Direct as for the ISS, then 0.3 kg water is required to hydrate the dried food [0.5 kg MD dried food * (0.8 kg ISS water / 1.77 kg ISS dried food), conservatively rounding up to significant figures]. This totals to 1.8 kg [0.3 kg water + 0.5 kg dried food + 1.0 kg whole food] of whole food per crew member per day. As an ISS crew member consumes 2.6 kg of whole food per day (1.77 kg dried food + 0.8 kg water], Mars Direct's 1.8 kg is suspiciously low (67% of ISS consumption levels).

For a conservative estimate, ISS levels of food consumption should be assumed (which includes only dry food). [[The Case for Mars]] presents good arguments for the inclusion of whole food, however, so further research should be done find accurate assessments of whole food requirements and consumptions rates on real space missions.

Jumpboy11j:

[[Image:MarsDirect.jpg|thumb|200px|right|The Mars Direct mission sequence.]]

Mars Direct is a proposed mission architecture, developed by [[Robert Zubrin]] and [[David Baker]] at [[Martin Marieta]] in 1990. Mars Direct uses a reduced set of technologies to land a small crew on Mars for a long duration science mission. This plan was summarized in the book, [[The Case For Mars]], written by Robert Zubrin and Richard Wagner. Mars Direct was innovative for its use of in situ resource utilization ([[ISRU]]) and for its use of direct launch from Earth to Mars without orbital construction or Mars orbit rendezvous. Mars Direct relies on separate outbound and return vehicles, and a pipelined mission architecture for improved redundancy. It has inspired several later proposed mission plans, including NASA's [[Design Reference Mission]].

== Terminology ==

There has only ever been one one Mars Direct proposed mission architecture. However, in some circles "Mars Direct" has become shorthand for any mars mission profile which reduces payloads and costs with ISRU and direct launch trajectories, including variants that make use of [[nuclear thermal rocket|nuclear thermal rockets]] and NASA's [[Design Reference Mission]]. The term "Mars Semi-Direct" was coined by Robert Zubrin to describe otherwise similar mission architectures that employ of Mars orbit rendezvous.

This wiki article is about the original proposed mission architecture, and includes secondary discussion of only those variants described by the original authors, Robert Zubrin and David Baker.

== Cost ==

In The Case for Mars, Robert Zubrin estimated the cost of development and operation of 3 missions at $20 - $30 billion.

==[[Mass Components of Mars Direct|Mass Figures]]==

''To see a much-expanded article focusing specifically on this information, see the article [[Mass Components of Mars Direct]]''

[[Image:MarsDirect.jpg|thumb|200px|right|The Mars Direct mission sequence.]]

Mars Direct is a proposed mission architecture, developed by [[Robert Zubrin]] and [[David Baker]] at [[Martin Marieta]] in 1990. Mars Direct uses a reduced set of technologies to land a small crew on Mars for a long duration science mission. This plan was summarized in the book, [[The Case For Mars]], written by Robert Zubrin and Richard Wagner. Mars Direct was innovative for its use of in situ resource utilization ([[ISRU]]) and for its use of direct launch from Earth to Mars without orbital construction or Mars orbit rendezvous. Mars Direct relies on separate outbound and return vehicles, and a pipelined mission architecture for improved redundancy. It has inspired several later proposed mission plans, including NASA's [[Design Reference Mission]].

== Terminology ==

There has only ever been one one Mars Direct proposed mission architecture. However, in some circles "Mars Direct" has become shorthand for any mars mission profile which reduces payloads and costs with ISRU and direct launch trajectories, including variants that make use of [[nuclear thermal rocket|nuclear thermal rockets]] and NASA's [[Design Reference Mission]]. The term "Mars Semi-Direct" was coined by Robert Zubrin to describe otherwise similar mission architectures that employ of Mars orbit rendezvous.

This wiki article is about the original proposed mission architecture, and includes secondary discussion of only those variants described by the original authors, Robert Zubrin and David Baker.

== Cost ==

In The Case for Mars, Robert Zubrin estimated the cost of development and operation of 3 missions at $20 - $30 billion.

==Mass Figures==

On page 93 of [[The Case For Mars]] Zubrin gives the following numbers for the masses of each component. These are the masses to Mars's surface and not to orbit. Basically all of the mass is assigned either to the Hab or to the ERV.

[[Image:TsiolkovskyCoin.jpg|thumb|A Russian Ruble coin with Tsiolkovsky on it]]This page is the introduction and entry point to the Tsiolkovsky Compendium (TC), the evolving record of an ongoing effort to collect, organize, and make accessible scientific and engineering results relevant to near-term space exploration and permanent space settlement. The long term goal of the Tsiolkovsky Compendium is to create a comprehensive database of the scientific and engineering data required to design, simulate, implement, and operate manned exploration missions and settlement initiatives.

=Guidelines for Inclusion=

The threshold for inclusion in the Tsiolkovsky Compendium is scientific and engineering validity. In science and engineering, validity generally refers to the extent to which a concept, analysis, conclusion or measurement is well-founded and corresponds accurately to the real world. Validity can be definitively established by experiment, or tentatively established by thorough and reasonable analysis or analogous demonstration.

Every piece of data, every analysis, and every result included in the Tsiolkovsky Compendium must be cited, preferably from multiple sources. Data, analysis, and results from peer reviewed journals, prior missions, and primary accounts (from reputable sources) are given more weight than non-reviewed articles, original research, or secondary accounts.

It is okay to have works-in-progress that are not fully cited yet, as long as over time progress is made to track down those references.

It is also okay to contribute your own work or estimates, however you must be explicit when you do so and cite references for any assumptions made. One's own work is anything not constrained exactly by simple physical laws with no estimation involved.

All internet sources should be cited with a link. For sources that are not online, Title and Author will suffice, although an online summary would be a nice addition.

As a side note, anyone who works on this project is called a TCer, which is almost universally vocalized and written out as "Tracer".

=Editing and Formatting Guidelines=

This information should be posted the best and clearest way that the Tracer's wiki-code skills allow. I suggest a quick read of one of the relevant wikipedia entries. In addition, LaTeX is enabled on this wiki, so if you know how to use it, feel free.

Each page edited by a Tracer should be put in the category Tsiolkovsky Compendium. This can be done by putting the text:

'''<nowiki>[[Category:Tsiolkovsky Compendium]]</nowiki>'''

At the bottom of the page.

=Current Projects=

This is a short description of each general area that the Tsiolkovsky Compendium is working on right now. For a full list of all the pages that are part of the Tsiolkovsky Compendium, please go to the [[Tsiolkovsky Compendium Category Page]].

==Mars Direct==

Our first project is finding specific engineering information about [[Mars Direct]]. If anyone can find the specific masses of all of the components that would be very helpful.

Mars Direct

2010-03-17T03:16:17Z

Jumpboy11j:

[[Image:MarsDirect.jpg|thumb|200px|right|The Mars Direct mission sequence.]]

Mars Direct is a scenario, devised by [[Robert Zubrin]] and [[David Baker]], that uses current technology to land a small crew on Mars. This plan was summarized in the book, [[The Case For Mars]], written by Robert Zubrin and Richard Wagner. At the time it was proposed, Mars Direct was innovative for its use of in situ resource utilization ([[ISRU]]) and for its use of direct launch from Earth to Mars without orbital construction or Mars orbit rendezvous. It also relies on multiple vehicles for improved redundancy. In the book, Zubrin estimated the cost of the mission at $20 - $30 billion. It has inspired several later proposed mission plans, including NASA's [[Design Reference Mission]].

Technically, there is only one Mars Direct design. However, in some circles "Mars Direct" has become shorthand for any mars mission profile which reduces payloads and costs with ISRU and direct launch trajectories.

Scott Davis has written a simulation, based on Zubrin's scenario, called [http://mars-sim.sourceforge.net/ Mars Simulation Project]
