The International Astronautical Congress in Guadalajara (Mexico), No. 67, expectedly brought a sensation - Ilon Musk made plans to colonize Mars. The light of the Elon Musk generation for more than an hour and a half talked about "Through thorns to Mars" (who cares, follow the link):
Making Humans a Multiplanetary Species Squeeze (for 4 minutes) - this beautiful movie, a great presentation in the style of Apple.
All the "paragraph". Roscosmos again late to Mars. All Pro-Pro-Polymer ™.
About the concept:
Elon Musk intends to settle a million people on Mars in order to "Save humanity from imminent death."
Passengers to Mars will be delivered by a spacecraft specially created by SpaceX developers that is able to comfortably accommodate 100 people and 450 tons of cargo on its board. Musk promises that by 2035, his engineers will be able to reduce flight time to 80 days (Be sure to remember this number, it will come in handy), and each shuttle will be able to carry out 12-15 flights.
“We are finding out how to take you to Mars and build a self-sustaining city to become a truly interplanetary view.”- said Musk.
When using traditional methods, the cost of a flight to Mars will be $ 10 billion per person. Musk said that you need to reduce the cost of travel to “As many people as possible wanted to move”.
“We should proceed from more realistic numbers, for example, given the average cost of a house, which in the US is $ 200 thousand (the average price of a house in the US)”- explained the inventor.
Fine! - cried the whole enlightened world. And the most important Nobel laureate, inspired and abandoned classes in the gymnasium of the White House, even visited the launch complex of a 45-year-old Canadian-American businessman (magnate and inventor). True, it was before the Trump Gate.
I do not know about you, but for me (who is not a member of "progressive humanity") this presentation left a bewildering perplexity. I will try not to load with formulas, but simply, “on the fingers”, to crap the proposed technical solutions and characteristics of the devices.
Well, what "flew" ... to Mars?
The first shots cause frightened. The service tower (on the left) is smooth and polished. Ideal for wrapping aerodynamic object.
No technical devices, filling pipelines, elevators, cables. Only crowds of people walking in a truck on a beautiful glassed-in terrace. Real service towers in the warm US climate look like this:
Or in our "eternal" permafrost something like this:
What is basically the same thing. The laws of physics, chemistry, economics can not be fooled. And he? Futuristic strict rocket lines and HTEC (Engineering the future) service towers. Without diverted masts, pipelines TC, elevators, service sites battalions of airfield services, capters of the ubiquitous ensigns - as it happened (is) in reality.
Of course, it is technically possible to make such a construction. Japanese car designers will design a typical soap box in 5 seconds.
It is possible to fill both stages from the bottom, having stretched the pipelines of the second stage filling through the first, the control of the PH parameters can also be carried out from the stern. Pourquoi pas? Question: what about the fig?
No, of course, there are such precedents (partial):
On the Proton cables, for example, go to a special contact pad between the engines. From below. But:
- His ancestor is still fighting MBR UR-500.
- The fuel components there are high-boiling (and Ilon also has supercooled methane and oxygen, in the liquid phase).
And yet ... "Feel the difference."
This is the Proton launch vehicle:
Impressive? Compare with the ITS starting complex!
"Fly" further. The first (it’s the only one!) Acceleration-march stage (reusable and).
Forty-two first-stage engines !!!!
"It's a fakinish, oh fucking shit ..." - so would my first "friend" Dmitry Konanykhin (a writer, by the way, and an "engineer", but this is secondary).
In defense of the pasta monster Ilona Mask put in a word. Part of 1
In defense of the pasta monster Ilona Mask put in a word. Part of 2
And I would be on 100% rights. I even would not blather in defense. "Sho again"? ™
Again the project of the “big silly carrier” a la OTRAG?
The Soviet H1 super-heavy-duty class rocket mysteriously smiles from non-existence (from the beautiful past), mumbling "well, well, let's see, porzhem."
However, both H-1 and Saturn-5 "rest."
The 10 500 monster weighing tons, throwing tons of cargo (or fresh meat) on NOU 550, tank diameters 12 m (remember, Saturn-5 has only 10м).
Quote: Dmitry Konanykhin
And here comes His awesome Majesty - Railway Envelope. You cannot change bridges, crossings, contact lines along the entire length of the route from the factory to the launch complex, so you must enter the design in the maximum size of the 3.7 meter.Horror. It is even strange that Dima is silent.
We proceed smoothly to the next stage - the habitable module, the Martian reusable ship, the “Spey Shuttle”, which went over the steroids.
Handsome? What I see? Rather, I do not see! I see no signs of a rescue system.
In principle, this is logical for a "flight to Mars" one way “Kill the peacemaker” immediately “comes to mind” (Written by Volodykhin Dmitry).
My webpage There, too, the Swiss Confederation got rid of ethno-abundances (all niggas, Latinos, Chinese and Slavs) of the planet Earth in such a costly way.
Mask designers are right here: SED for hundreds of people and the crew will be completely inadequately expensive, heavy and daunting. Unrealizable in principle. SED for passenger cabin liner seen? That's it. And if the crash at the start? It will be very offensive.
This is not even “Columbia” and “Challenger”:
The death of the shuttle Challenger and the seven astronauts NASA
The crash of the American shuttle "Columbia"
A minute of silence is not enough here, here the International Criminal Court clearly smells and smells of Fatu Bensuda. Okay. They know better.
Oh yeah, yet.
No heartburn? The spacecraft 21 century proportions and number of windows reminds fantastic projects of the dawn of space exploration:
Or a glass house in space:
For reference: in reality, engineers always spent their talents on making portholes as small as possible and less in surface area. Laminated glass (capable of withstanding vacuum and micrometeorites) weighs a lot. The coefficient of thermal expansion should be close to zero (and this is only a special quartz).
Visual история, as fought with portholes in the American lunar module:
Example: Dome (MKS module)
Mass during launch - 1 805 kg, glass thickness - 10 cm. Still, all the windows on the outside are equipped with automatic shockproof devices (dampers) to protect the module from micrometeorite and space debris.
Next, we dissect one of the strangest presentation frames.
I do not believe my eyes! The main and only (the most difficult) stage with 42 LRE "Raptor" returned to the launch complex, to the launch site. Wow! Fake? "Coincidence? I don't think so!"
I will explain my outrage with this crying jamb. As is known, the PH starts vertically, with a pitch angle in 90 gr. The task of the first stage is to quickly go through the dense layers of the atmosphere (gain altitude), then the pitch angle tends smoothly to 0 gr.
After all, it is necessary not only to raise the payload to the altitude from 150km (NOO), but to give it a speed close to the first comic (from 6 km / s -7 km / s).
According to my sentiments of the "experienced rocket", the separation of the Martian ship and the stage will occur somewhere on the meridian of Tenerife.
The argument is the launch route of the 51,6 PH Soyuz:
Now try to calculate the fuel costs of returning our stunted first stage to the 31 site. And all three? This is how much fuel you need to:
- to extinguish the linear speed in 6 000м / с, and then return the container (with such mid-section and such mass) to the starting point from the height 70-100km?
-and if you land on an expensive one (and you must give it away, e is beautiful), the launch complex will go wrong and it will blabahnet?
After all, it was already:
Monster to fly to Mars is still not
Quote: Dmitry Konanykhin
Macaroni Mask. This is a pasta! First, the return to the place of launch is a great loss of the payload. Secondly, why bother to sit in your own starting table? Saving time to transport the first stage? Well, do not make me laugh. Logistics is visible to a third grader.
Smoothly go to the "main dish". The idea of refueling in orbit is quite sensible. And long nurtured inquisitive cosmic minds. The only question is what to fill? According to the SpaceX presentation on the ship, there are Raptor engines operating on supercooled methane and oxygen (needed for a braking impulse when approaching Mars, maneuvering in orbit and landing, since the electric propulsion in 200kW does not roll here). So, all the time of the flight to Mars, the fuel components will be stored in the tanks for landing! In large space, in the zone of action of our star "by the name of the Sun" this is a big problem.
Many people think it is terribly cold, but no - it is terribly hot. The entire flow of solar wind heats the design of the spacecraft (Skylab remember, the guys almost boiled, umbrellas used, while the air conditioning system was restored). Proper heat to go no where. Let me remind you, the colonizers to Mars flies 100 heads, each body radiates (except for natural waste) 70-100 watts of heat. Where to go? There is no convection. Only radiation (temperature not those) or ablation (mass in short supply). It is very difficult to dump excess heat in a vacuum (Dewar flask). And without thermal insulation of tanks, supercooled methane and oxygen will heat up and evaporate. Drain somewhere.
That is why real spacecraft in deep space take with them stored in liquid form when room temperature nasty heptyl and amyl (or similar high-boiling muck), or Н2О2 at worst.
Recall Voyager: The official website of the Voyager program long summers to him, by the way. Cryogenic stages live in orbit at best for hours. Yes, tanks can technically be insulated, but it will be a huge loss of weight, money and useful volume.
We will virtually visit the RSC Energia museum and consider tanks for the Buran, in which liquid oxygen could be stored for weeks.
Bachek tiddly, insulation thickness is significant. And if not bachyok, and bachische? Need any comments?
Beautiful devil. Solar panels already in 200 kW.
Alas, designers-designers have won over engineers again. Knots turning the solar panels are not observed. The systems of orientation of the Sat.
Which is easier (more energy efficient) to turn the tower tank on the target or the entire tank body? WoT players will support me. In the presentation, by the way, the ship ignores the direction to the Sun. Accordingly, solar radiation, too. A flight to Mars along a “non-Gomanov” trajectory (I remind you about 80 days) is a separate song. Why "non-Gomanovskaya", so the presentation can be seen. Everyone knows (I hope) why now interplanetary stations fly to Mars for half a year , instead of 115 days on average? It's very simple - the faster we want to fly, the more we need to spend fuel on it.
The most economical option is on the top left. Gomanov transition. Do you want faster - pay by the fact that instead of the payload you will have fuel.
And now the question - how fast and expensive flight will be combined with an affordable ticket to Mars (100 pieces of Baku for the head)?
And for dessert. Landing on Mars.
Oh, mom. All this zhlygu on Mars to plant? Solar powered, electric propulsion? Heat Shuttle / Buran, you know how much weighed?
Are they not watching their own films?
I recommend to have some fun: "Air retardation and landing difficulties in a rarefied atmosphere of Mars"
space simulator orbiter
The simulator emulates all possible errors - you can break the ship on Mars with a high vertical speed, fly back into space without a chance to return or approach the surface with a large horizontal speed and break the ship, despite the near-zero vertical speed.
In general, landing on Mars is more difficult than on a body without an atmosphere (like the Moon) or on a body with a "normal" atmosphere (like the Earth).
The atmosphere does not allow to occupy an arbitrary position, you have to fly forward with a fairing, and to have it with a certain angle of attack, roll, aerodynamic controlled surfaces, remote control are required. Everything should be "heat resistant."
On the other hand, it (the atmosphere) is not enough for the full change (deceleration) of the characteristic speed (delta-V) kilometers per second at 6 minimum and for the full performance of the wings and other aerodynamic surfaces. Mars has a very dystrophic atmosphere (and poorly understood). The average pressure on its surface in the area 0,5% of Earth. All kinds of storms. MCC no, Hydrometeorological Center is also not observed.
It is inconvenient to use it for braking, and it is impossible not to take it into account either.
The monstrous presentation Mask showed a typical manager project. Which, however, was enthusiastically received by the public and became a sensation.
Fresh news - hundreds of people write to SpaceX, wanting to fly to Mars, obviously believing in the possibility and availability of such a flight.
If we had this - I would have cried about the victims of the USE.
For reference: the primary task of the Mars Colonial Transporter was the delivery of the future colony to Mars. However, as Mask recently noted, the rocket can go further. Therefore, the rocket offered a new name: Interplanetary Transport System.
Ahead of us "waiting": JUPITER, ENCELADUS, EUROPA and even SATURN
I swear: the ship “Hermes” in the previously mentioned masterpiece “The Martian” is starting to look like a fully developed project: it has solar panels turning, there are heat exchange system radiators, a reactor and an efficient engine, and a quite adequate number of people in the crew. I won’t even remember about carto on excrement (entertaining and useful chemistry / biology).
But he started so well:
And this presentation resembles some salsa / salsa:
In the article I mentioned the methane-oxygen LRE of the closed cycle RAPTOR and electric propulsion engines. If there is interest, I will be happy to sort them out. But this project is more serious than ITS and is already working.
Carbon fuel tanks are not mentioned, and there really is progress:
Another giant SpaceX project also stayed behind the scenes: last week, SpaceX made another sensation by submitting a request to the Federal Communications Commission (FCC) for permission to launch 4425 satellites.
Meanwhile №1:It became known what policy Donald Trump intends to pursue in relation to the study of outer space. Emphasis will be placed on the study of deep space and the development of manned space flight. According to Trump's space policy adviser Robert Walker, the newly elected leader intends to devote more attention to deep space and the development of manned cosmonautics. One of the first reforms will be the re-establishment of the National Space Council, liquidated by Bill Clinton. The organization will oversee all American space projects that will be subordinated to one task - “the study of the entire solar system by man by the end of the century”. The first target is a manned flight to Mars.
What a Trump administration means for space
Meanwhile №2:The editors of Nature, one of the most authoritative general scientific journals, have declared plans to colonize Mars unviable.
Fed up of Earth? Try mars
By the way: on NASA's 2005 website, flash games are dangling, including the “Find the way back to Earth” puzzle and the Mars Rover simulator with three levels - “Mariner Valley”, “Polar Cap” and “Mount Olympus” and t .d
Shl. Those who were able to finish reading this to the end, cause me a true admiration.
