Traveling to the stars and other planets is the cherished dream of mankind, however, huge distances separate us from the goal. Many ways have been proposed to overcome them, but modern engines still do not provide an opportunity to fly far from the Earth.


Rockets and spaceships are propelled by liquid and solid propellant engines, and there are also electroreactive, and, hopefully, engines powered by nuclear energy are on the way. But they still cannot deliver us to other people's stars.

This test will allow you to find out how "in the subject" you are and whether you can become a spacecraft developer.


NASA planned to fly to Mars by the end of the 70s. For the flight, it was supposed to use this nuclear rocket engine. They also wanted to use it as the upper stage for the Saturn rocket.

The NERVA (Nuclear Engine for Rocket Vehicle Application) program was closed in 1972 - despite the fact that the engine passed many successful tests on the ground, and the program itself had strong political support.

The head of the Rosatom corporation once said that Russia is creating a nuclear engine that will make it possible to fly to Mars in 45 days. What is he talking about?

YaEDU, a joint project of Roskosmos and Rosatom, is being designed for a spacecraft with the working title "Transport and Power Module" (TEM), or simply "Space Tug".

The SuperDraco liquid propellant rocket engines installed on the Crew Dragon to provide rescue of astronauts in case of emergency situations, and the Draco orbit correction engines of the same spacecraft are powered by this fuel pair.

Fuel using monomethylhydrazine (fuel) and dinitrogen tetroxide (oxidizer) allows the engines to be restarted many times, including after a long time after refueling and starting the ship.

The flight module MTM (Mercury Transfer Module) of the BepiColombo mission is equipped with four such engines.

The T6 ion engines, created by the British company QinetiQ for the flight to Mercury, are the most powerful of such engines ever used in space.

In theory, this concept engine can develop the maximum thrust possible for a jet engine, allowing speeds close to the speed of light.

A photon, as you know, has an impulse; accordingly, when it flows out of the engine, it creates a jet thrust.

Photon Nuclear Pulse Engine Light Sail 6/10

The Orion project, developed in the United States in the middle of the last century, envisaged the creation of a manned spacecraft for the study of interplanetary and interstellar space. What engine should have sent him to the stars?

According to calculations, a nuclear-pulse engine would allow Orion to accelerate to a speed that would be equal to 5% of the speed of light.

NRE will have an extremely high specific impulse compared to modern engines. Which of these engines has a higher specific impulse compared to other nuclear engines?

It is believed that the specific impulse of a gas-phase nuclear rocket engine will be 30-50 thousand m / s. This is the highest among such engines.

The idea of ​​the concept of such an engine came to its author after watching the series "Star Trek".

In 1994, physicist Miguel Alcubierre proposed the concept of a space-bending engine that could allow a spacecraft to reach superluminal speed.

Liquid rocket engines were used for takeoff from the lunar surface in the Apollo program. What fuel components were used in it?

Extremely toxic dinitrogen tetroxide and aerosine are rocket fuel, which is a mixture of unsymmetrical dimethylhydrazine (UDMH) and hydrazine in a 1: 1 ratio (by weight).

TTRD, a solid-propellant rocket engine, uses solid fuel and an oxidizer as fuel. Where was the most powerful solid rocket engine ever used?

A pair of solid-propellant rocket boosters provided 83% of the launch thrust of the MTKK Space Shuttle.
