Try Landing InSight on Mars (Without Exploding)

NASA parked its InSight Landmark in Mars. Yes, Mars. It's a great infrastructure because Mars did not do any missions. No wonder Marsen missions have concerns.

For this particular mission, the Territory, protected by a warm heat, slowed the atmosphere of Mars. After that, he opened a high-speed parachute at high speed speeds. In the end, he traveled to the final part of the trip from the parasail to the final part of the trip to control the fall.

Now the real question, anyway: Can not handle InSight landing? If you made a manual landing, would the robot survive? Let's find out.

Before entering the game, we will go to the basic physicist. It's too manageable, I'm around the rocket part of the rocket for this task. During the descent of the dump, there are basically two forces to act there. The gravitational force is downward and the rising force of the spacecraft's rockets. Gravitational force depends on the local gravitational field and the bulk of the spacecraft. In Marsen, the gravitational area is slightly lower than the ground, with a value of 3.71 Newtons per kilogram (9.8 N / kg compared to the Earth). The gravitational area is always strong, close to Martha's skin.

Although the gravitational field is continuous, it is not a mass of space. When he uses his rockets, he loses mass (because the rocket's rifle fires). This means that the force of gravity changes slightly, but, of course, the nucleus is not fuel. The total mass of the fuel is around 16% of the total mass.

The variable mass of the spacecraft also affects its movement. According to the principle principle, the total force (gravitational plus rocket) is the same as the change in the momentary change of momentum. However, the torque is a product of mass and speed. Therefore, the constant net power of the spacecraft will be an impetus that will change the constant change. Yes, it's hard to do.

OK, leave in the game. Here's how it works.

  • You need to start with more than 50 meters of speed above the ground.
  • You get adjusting thrust momentum.
  • Changing the speed of the rocket depends on the number of boosts.
  • The rocket mass change also depends on the number of rocket boosts.
  • If you want to get a rocket to reach the ground, if you travel less than 1 m / s (it should be slower).

That's it. Click "to start" and then slide the slide below to boost the rocket. The program also displays the vertical speed and the number of fuel you left. This is basically the dimensional version of the classic Lunar Lander.

It seems more difficult. The problem is that we believe that it is a direct connection between forces and movements, that the force is moving faster. Aha! It's not so fast. In fact, a greater force makes a bigger change in movement. As you move forward, you need to increase strength to accelerate as you fall. But if you give us too much impetus, the landlord is slowing down, in fact, it starts to accelerate in the opposite direction. That's not landing, that's coming out.

Now to do housework. Get out on the ground (safely) in a short space of time. Now it creates the algorithm that controls the magnitude of the impulse (non-user) that is trying to land in the shortest time. It will be fun.
