Space rocket made from nanocellulose

Nanocellulose is eight times stronger than steel if weight of steel and nanocellulose is compared. Perhaps nanocellulose can also be hardened with graphene.
Cellulose is wood pulp, so it is cheap, it is basically paper, but making nanocellulose is expensive, like anything that has “nano” in it.
But because cellulose is paper, space rocket can be basically build like cardboard that is used in cardboard boxes. Cardboard boxes have two-layer cell structure, similar simple two layer cell structure can be made from nanocellulose perhaps. Honeycomb etc. structures can be used, and that kind of structure that was used in Mosquito aircraft and other plywood aircrafts.
But basically outer surface skin of rocket and fuel tanks can be made from this nanocellulose cardboard, but in this case cardboard is stronger than steel. Making cardboard structure from wood pulp is easy. So building space rocket is also cheap, it is like space rocket made from cardboard.
No need to reuse rocket, perhaps rocket engines have their own heat shield and they return to earth but rest of the rocket burns when it enters atmosphere.
Outer skin of rocket can be protected from heat when rocket rises to space if outer skin of rocket is covered with ablative heat protecting material that burns away when rocket rises through atmosphere.

Only problematical thing is cost of nanocellulose, but it is possible that cost comes down if mass production of nanocellulose begins. Motorcycle is already build from nanocellulose, and car parts are planned to be made from nanocellulose. So it is possible that price becomes much cheaper than it is today.
Instead of making space rocket from metal or composite materials, simply making it from cardboard is possible. Construction of it from cardboard is also much simpler to build than using other materials. Raw material price (nanocellulose) is nowdays a problem but price may come down quite rapidly when mass production of nanocellulose really begins.
But sheer simplicity of ease of construction when space rockets can made from cardboard instead of composites or metals makes nanocellulose good opportunity, actual construction of space rocket should be ultra-super cheap if cardboard can be used in its nanocellulose form. Also other hardening materials like graphene can be used so it is then nanocellulose-composite.

If space rockets can be build from nanocellulose, perhaps satellites can be build too. Satellites and space structures made of nanocellulose. But nanocellulose is wood, and how wood behaves in outer space conditions, in vacuum and extreme heat/cold conditions? Nanocellulose is eight times stronger than steel when measured by weight. Nanocellulose is also expensive and it is manufactured only in small quantities, so making payload of space rocket made of nanocellulose is perhaps cheaper than making whole space rocket, minus rocket engines, from nanocellulose. But that depends how good or bad nanocellulose is in space, or is it suitable at all long duration in space. Cheap satellite structures are however possible if nanocellulose is used and its price drops. There are cubesats an all kinds of cheap satellites. I don t know how nanocellulose can make those cheap satellites more efficient if nanocellulose is used in their structures, or does it make them only more expensive? And if in big satellites or even space stations nanocellulose is used as structure material what advantage it has or is it worse than usual metals and composites used in them. But it is possible that price of nanocellulose drops so that even space rockets can be build made of nanocellulose. And perhaps space telescopes too, if nanocellulose is suitable for them, as structure material. But it is possible that nanocellulose is not suitable for long duration in space.
If nanocellulose is combined with some other material, it is then nanocellulose composite. For example graphene, if nanocellulose is combined with graphene it is then nanocellulose - graphene composite.
This is continuation of previous post “Ecological alternative to plastic” that is in Robin Hood Coop Discourse netpages.

If nanocellulose, which is eight times stronger than steel when measured by weight, is used for example to build space rocket (rocket engines can be recycled and engine compartment has its own heat shield and it returns to earth, other parts of rocket when enter back to atmosphere burn, nanocellulose is basically just wood pulp), space rocket outer surface needs some sort of heat protection against atmospheric drag heat, sort of ablative layer which erodes and protects rocket.
If satellites and space stations are build using nanocellulose, they too need some protective outer surface against conditions of outer space (heat, cold and vacuum). There are reflective surfaces used in space stations against heat of the sun, similar surfaces can be used in nanocellulose structure satellite or space station. This outer surface can have other properties too, not just heat protection, that protects satellite or space station in cold almost absolute zero temperature in shadow side in space and against vacuum if space station is build. The nanocellulose structure of satellite and space station can also be thick honeycomb structure, so that heat etc. only affects outer parts of satellite / space station honeycomb structure and rest of thick honeycomb structure not as much. This same principle can be when building space rockets made of nanocellulose, nanocellulose honeycombs are in thick honeycomb structure where distance between inner and outer surface of nanocellulose honeycomb structure in rocket skin can be several dozen cm but that honeycomb structure is lightweight because actual honeycomb cells have thin walls, so overall weight is not much. The further away honeycombs are from rocket outer surface less are they affected by atmospheric heat. Only those near outer surface are affected by heat but outer surface is protected by some ablative heat protection material.
Perhaps is possible to build space rockets and space stations and satellites made of nanocellulose.
It is perhaps also possible to mix nanocellulose with other materials, making nanocellulose-composites, with different heat-, cold-, vacuum resistant properties etc., and different strength etc. properties.

If space rocket is made of nanocellulose, eight times stronger than steel when measured by weight, it is perhaps possible that fuel tanks and outer surface of rocket is connected with honeycomb structure, this honeycomb structure fills empty gaps between outer skin of space rocket and fuel tanks, so whole rocket is one rigid structure, fuel tanks and rocket outer skin are one and same structure, outer surface of honeycomb structure is outer skin of rocket, inner surface is fuel tank walls, and in between are honeycombs made of nanocellulose or other material. There is some distance between fuel tanks and outer skin of rocket, but the space in between is filled with honeycombs or other geometric shape hollow structure. So rocket skin and fuel tanks are connected to each another, they are same rigid structure, honeycomb structure that connects outer surface of rocket and fuel tank walls. Outer skin of rocket is covered by some material (aluminum?, composite?) which is the normal material that is used in the rocket outer skin, or perhaps nanocellulose is also used to cover rocket skin and some heat protection material then covers it. Fuel tanks walls can be that material (aluminum?, composite?) that is usually used in rocket fuel tanks, or if possible they are nanocellulose too. But in between rocket skin and fuel tanks is honeycomb structure that makes whole rocket rigid structure, fuel tanks and rocket outer skin then are not separate structures. Other materials can also be used, not only nanocellulose, if is possible to make rigid honeycomb structure that covers rocket innards. But nanocellulose is wood pulp, practically just cardboard that is stronger than steel, so making cardboard structure that is the size and shape of space rocket is then the space rocket, with honeycomb or other type of hollow but rigid structure inside.
Other possibility is that innards of rocket between fuel tanks and outer skin is filled with foam that is made of nanocellulose. Similar like foam formed by blowing air on soap water. This rigid hollow foam forms the structure of space rocket, so that whole rocket is rigid structure from outer surface of rocket to fuel tanks, and this rigid foam fills all empty spaces inside space rocket, making structure light but strong. If honeycomb etc. structures are not used to fill the empty spaces of rocket.
Foam plastic is used in construction, in isolation of pipes etc. This is like foam plastic but made of nanocellulose. Which is eight times stronger than steel. Because nanocellulose is so strong material how then this foam structure can be formed inside rocket? Perhaps some kind of rocket-size mold is used and whole rocket is made using rocket-size mold. I don t know if nanocellulose which is stronger than steel, is it strong from the beginning or is it softer in the phase when it is only early forming stage. If it is soft then it can be perhaps blown like plastic foam to make structures with this lightweight foam. Or molded in mold to make honeycomb etc. shape structures.
Also airplanes can be build using nanocellulose, nanocellulose structures inside aircraft outer skin, using similar honeycomb etc. or hollow foam structures. Different composite materials can be perhaps made using nanocellulose as one component.
Perhaps aircrafts can be made using mold manufacturing, then aircraft size molds must be used.

Cellulose is a living material (woodpulp) , so if nanocellulose is made, perhaps is possible in the future that cellulose is put to some mould that has the shape of airplane structure or space rocket structure, and in this mould, using some process, cellulose is processed to nanocellulose, stronger than steel. And perhaps nanocellulose mixed with some other material so it is then composite.
Nanocellulose is made using mechanical or chemical process, and cellulose nanofibrils are those that are stronger than steel. If there would be some chemical or organic process that makes that strong type of nanocellulose, then cars, space rockets and aircraft structures could simply be “grown” instead of building them, grown in mould and then processing in the same mould so that structure inside mould becomes strong type of nanocellulose. So instead of building car-, aircraft- or space rocket structures, they are just grown in mould like in petri dish and processed in the same mould so that cellulose becomes nanocellulose.
Organic structures, that type like bones of birds, which have hollow bones, that are light and strong, can perhaps be grown to be car structures or aircraft or space rocket structures.
Organic prosthesis types are used in medical industry, made from biological materials, perhaps nanocellulose structures can be made using something similar manufacturing like organic prosthesis.
But making nanocellulose from dead organic wood pulp is the way that nowdays nanocellulose is made (or at least cellulose is not living material anymore when it is processed chemically or mechanically when typical nowdays nanocellulose manufacturing process is used), and that will work too, then nanocellulose is just like any other material, metal or carbon composite that is used to build airplanes and space rockets. But perhaps nanocellulose “cardboard” can be made, not so different than normal cardboard, but this cardboard is stronger than steel, so then paper factory can build cars, airplanes and space rockets using this nanocellulose cardboard, cheaply.
Other ways to use cellulose (woodpulp) is to make material from wood fibers that replace plastic in packing material, or actually those wood based materials can replace all plastic products altogether, and cotton in clothes: Arboform, Woodly, Sulapac, Paptic, BioGreen Bags India, UPM BioVerno, and ExpandFibre Project, New Cotton Project, Spinnova, Infinited Fibre Company, Biocelsol, Ioncell, Fortum Bio2 Textile, Kuura textile. And Leaf Republic in Germany, using palm leaves to replace plastic.

There are other organic materials that can be used to build space rocket, and that perhaps are cheaper than nanocellulose. From netpage AZoM com “Plastics that are stronger than steel” and “Can wood rival metal hardness?” From netpage hempfoundation net “Is hemp stronger than steel? How?”
So perhaps space rockets can be build using just wood or hemp or organic tulip-based material (processed) or some other cheap organic “plastic”. Perhaps even some sort of “plywood space rocket” can be made. If hemp is 2,5 times stronger than steel and its compressive strength is 6 times stronger than steel. Those other organic “plastics” mentioned in those net articles have perhaps even better properties.

If there is material that is stronger and lighter than steel or composites (weight to strength ratio) it can be used in space rocket construction. There are organic materials based on tulip, pearl, or hemp in netpage AZoM com “Plastics that are stronger than steel”, and in AZoM com “Can wood rival metal hardness?” is process that turns wood 23 times stronger than normal wood. If those wood, hemp or tulip based materials are stronger than than steel why they are not used in space rocket construction?
Even natural wood has about two times tensile strength of aluminum and natural wood has weight to strength ratio that only some composite materials can beat. But those materials improve wood strength or use tulip, hemp or pearl as material. If wood can have 23 times strength of normal wood, it then beats most if not all known composite materials in weight to strength ratio. Why not then building space rockets made of wood?
SpaceX first used composites, but then switched to steel for building space rockets. If processed wood has much better weight to strength ratio and purpose is to build space rockets then this new wood material is ideal space rocket building material. Hemp is 2,5 times stronger than steel and it is already used by car manufacturers in car parts. New tulip- or pearl based organic materials can also be used for building space rocket.
Using organic material means that building material can be grown, it is not like some metal or mineral whose manufacturing process is expensive and complicated . Perhaps molds can be used if building material is organic, space rocket structure molds, like construction of plastic structures uses molds.
Organic material can burn, so rocket outer surface must be protected with some heat protecting material, perhaps ablative, that prevents rocket from burning away when it rises through atmosphere when air drag heats it. Rocket engines can be recycled if they return to earth with their own re-entry heat shield.
SpaceX tries to build space rockets as cheap as possible, if instead of steel SpaceX would use some of those new organic materials space rocket would then be really cheap and have more payload because structure has better weight to strength ratio, so that way too payload price is cheaper.
Birch and other wood is used in aircraft construction even today in dozens of different airplane types, and plywood was used extensively in WW2 in aircrafts. Perhaps similar plywood that was used in WW2 aircrafts can be used in space rocket construction. But that new processed wood that is 23 times stronger than normal wood, and other organic hemp-, pearl-, tulip- etc. based materials are perhaps even better.
Not only space rockets, but also cars, trucks, houses, buildings, perhaps ships (wooden ships?) can be build using those new organic materials cheaply. Perhaps molds can be used building those structures. Cellulose (wood) is used as pulp to make cardboard and plywood, using molds. Nanocellulose is also strong material, but expensive. But if this new processing mentioned in AZoM com netpage makes wood 23 times stronger than normal wood, stronger than steel, then cardboard and plywood made using this same process has then 23 times strength of normal wood, stronger than steel?
So instead of making space rockets made of steel SpaceX could just go to some nearby forest and take from there some birch and build space rocket using it, if even normal natural wood has good strength to weight ratio. Or plywood is better. But best are those new organic materials that are much better than steel as building material with their weight to strength ratio, and probably cheaper too. Space rocket fuel tanks and other structures can perhaps be build using those materials, all structures except rocket engines and their plumbing.
Spider silk is also used in new wood based materials, making some sort of spider silk wood fiber composite. Googling searchwords “spider silk wood plastic Markus Linder”. Spider silk is very strong material. If spider silk based composite materials are among those organic materials that can be used to build space rocket.
But wood can also be used in consumer products, to replace plastic, wood based organic “plastics” can almost completely replace all plastic products, those “wood plastics” have trade names like Arboform, Woodly, Sulapac, Paptic, BioGreen Bags India, UPM BioVerno.
Also cotton can be replaced in clothes using wood based materials: ExpandFibre Project, New Cotton Project, Spinnova, Infinited Fibre Company, Biocelsol, Ioncell, Fortum Bio2 Textile, Kuura textile.
Also palm leaves etc. leaves can be made to food plates: firm Leaf Republic in Germany does just that.

About space rocket made of wood: “Wood made foldable and stronger than steel”, “Researchers have now made wood that you can fold and mold”. If wood material is strong but it can be made to styrofoam type structure or soap bubble type light but strong structure it can be used to build space rocket or airplane. Other material but not wood: “New lightweight material is stronger than steel MIT news”.
Also: “Can space rocket be made of wood?”, “What spacecraft(s) incorporated real wood structural elements?” Googling “wooden satellite”, WISA Woodsat and “Japan sending wooden satellite to space”. Googling “wooden heat shield”. If wood is fire resistant and strong some kind of reusable rocket stage that returns to earth like space shuttle can be build, protected by heat shield (not wooden heat shield if wooden heat shield is too heavy, but returning to atmosphere rocket structural parts can be made of fire resistant wood), and SpaceX is planning rocket stage that returns to earth from space and needs heat protection, and this heat shield is steel. Or just space shuttle itself made of wood.
But rocket that launches satellites to space can be made of wood, not recycled except rocket engines, so only rocket engines need heat shield.
“Scientists have developed a way to make wood as strong as steel”, “Crushed wood is stronger than steel”, “Manufacturing of high strength plywood composites”, transparent wood Wikipedia article, “The case of high-strength composites in the reinforcement of structural timber”, freepatentsonline “High strength composite veneer articles”, “High strength, lightweight, co-extruded wood flour-polyvinyl”, “Dimensional stability and tensile strength of wood plastic composite” 2020, “High mechanical strength wood polymer”, “Eco-friendly wood fibre composites with high bonding strength”, “Bending strength of wood treated with propolis extract and silicon”, “The strength and stiffness of oriented wood and cellulose-fibre materials”, and chinese patents that refer to “High strength wood-plastic”.
If wood is part of some composite, another part may be graphene, so result should be ultra-strong wood that can be made to build space rocket or upper stage of space rocket if graphene is expensive. Nanocellulose can be used also but it is expensive also. The main point of wooden space rocket is that it is cheap, cheaper than space rocket made of composites or metal. If it has better weight to strength ratio than metals and composites it is even better. If rocket is non-reusable, then wood, modern “super wood” materials, or hemp-, tulip-, pearl- etc. super strong organic materials can be used. If organic material is both strong and fire resistant, then space rocket using organic materials can be reusable booster vehicle. Rocket outer skin can also be covered with some protecting material, perhaps ablative that protects from heat.
Also airplanes, such as jumbojets that are expensive to build, and cars and trucks can be build using strong but cheap organic materials. Perhaps ships also. Wooden structures are often build using rather unskilled labour, unlike workforce needed to build metal or composite structures, so building structures using wood (or other cheap organic material such as hemp etc.) is cheap that way too. So airplanes, cars and trucks can be cheaper than they are now.

If space rocket is made of nanocellulose, or “super wood”, or hemp-, tulip-, pearl- etc. based organic material that has good weight to strength ratio, and that organic material is reasonably cheap (including composites where this strong organic material is mixed with some other strong material, like graphene), it is perhaps possible to make some sort of foam like styrofoam (plastic foam) structure using this material, or soap bubbles- type lightweight but strong structure. This lightweight but strong foam structure can fill all empty spaces inside space rocket, fuel tanks, plumbing, rocket engines etc. excluded. When rocket rises through air to space those foam or bubble filled structures have air inside their foam bubbles. In high altitude outer air becomes thinner and in vacuum air pressure inside bubbles when compared to vacuum becomes substantial. This increasing air pressure can make structure stronger, internal air pressure plus structural strength of air bubbles/foam material keeps space rocket structure strong and light. Perhaps even one stage rocket can then reach orbit, if this foam is some very strong but light material.
Also space stations and rocket stages that go to Mars can perhaps use similar lightweight air/gas strengthened foam/bubble structures. Or this styrofoam type structure is blown in space in between two flexible plastic sheets that form the wall of space station (inner and outer wall) and plastic sheets are folded and packed when launched in rocket to space but in space super strong “styrofoam” is blown into those plastic sheets that when blown to full form mold of space station, so space station can be folded in payload bay and only when it is in space it is filled with super strong “styrofoam” and perhaps gaseous nitrogen, argon, or helium inside air bubbles. Nitrogen, argon or helium is in liquid form when rocket is launched to space and only in space made to gas that fills the air bubbles. It also must remain in gaseous form in cold space, so thermal insulation in outer plastic sheet wall of space station is needed.
The “styrofoam” must be some material that is woodpulp- or plastic foam in its liquid phase- like soft material first, but then it becomes strong, perhaps stronger than steel, when it fills the flexible plastic or composite two-layer mold of space station.
Also space rocket stages that go to Mars can perhaps be just blown in form in space using this soft mold + “styrofoam” filling. Rocket stage that goes to Mars is packed in folded mold form in booster rocket s payload bay, in space this flexible mold is filled with “stryrofoam” and it then becomes habitable Mars rocket stage.
Also only air/gas can be used to make “soft” folded in payload bay- space station, Bigelow Aerospace does just that, and perhaps Mars rocket stage can have similar soft extra habitats that Bigelow Aerospace does.
