Elon Musk has sounded the approximate cost of moving to Mars

According to the founder and head of the private space company SpaceX, once the flight to Mars will be available a lot number of people. Suffice it to sell their homes on the Land and invest the money in space move. In addition, Musk even offered a bonus for those who still dare: the ability to return back to the Earth will be completely free. If survive.

To a question from his readers «on Twitter» how expensive it will be worth the opportunity to go to the moon/Mars with the use of missiles for multiple launch, Musk said that everything will depend on the volume of most of these launches.

"I'm sure that one day moving to Mars will cost less than $ 500,000, and maybe even less than $ 100,000", — wrote a Masque.

According to the head of SpaceX, this cost will mean that most people from developed economies can, if desired, having sold his house to Finance moving to another planet.

Such available space travel Elon Musk wants to do with Starship – fully reusable spacecraft, designed for a comfortable delivery the centurion person to Mars in one launch, and in the future and beyond. Recently, the company has already conducted the second test firing of the significantly upgraded engine Raptor that will be used for suborbital test flights. They plan to start in March this year.

In the same Twitter Musk said that a rocket engine for spacecraft Starship ahead of the RD-180 on the pressure level in the combustion chamber.

"According to the plan, the thrust must be at least 170 tons. The engine has reached 172 tonnes, and the pressure in the combustion chamber reached 257 bar," explained Musk.

A Little later he added that that the pressure has exceeded 268,9 bar that allowed SpaceX to break the record of Russian RD-180 engine.

the RD-180

Of Course, such a statement could not stay away. The words of Elon musk decided to comment on the chief designer of NPO "Energomash" and also the developer and manufacturer of the family engines RD-180 Petr Levochkin, whose words are given on the official website of the state Corporation «»:

"the Company creates a SpaceX Raptor engine components at oxygen and methane, or as is customary in the Russian classification scheme "gas-gas". In such schemes a level of pressure in the combustion chamber is not something outstanding — in their designs for these schemes, we are laying the pressure level in the chamber is more than 300 atmospheres. And the parameter is the pressure in the chamber is not the output characteristic of the engine, such as thrust and specific impulse.

However, Mr. Musk, without being too technical, does not consider that the RD-180 engine for rocket vehicle Atlas will use a completely different fuel scheme — "oxygen-kerosene", and that other parameters of engine operation. It's like comparing diesel and gasoline internal combustion engine. But if you consider that "Energomash" has certified the engine with a 10% margin, the pressure in the combustion chamber of the RD-180 is higher than 280 atmospheres.

Despite the fact that our companies are competitors, we as engineers welcome the first successes of colleagues from SpaceX in the field of rocket propulsion. Indeed, when developing the Raptor engine American engineers reached a record level of pressure in the chamber. This indicates a fairly high level of developments and production processes in SpaceX".

In the future, SpaceX intends to create a universal version of Raptor, which will be used in the booster for space launch vehicles, and the vehicles for reaching the desired orbit and maneuvers. This will not only save development time, but reduce the cost of Assembly and launch.
