Die on Mars

thump……

thump……

thump……

thump!

Ophiopogon japonicus could clearly hear her own heartbeat, which was beating tenaciously and powerfully in her chest.

Logically speaking, sound waves in the surrounding vacuum cannot propagate, and the universe should be completely silent. However, Ophiopogon japonicus can actually hear many sounds, including his own heartbeat, the sound of water sloshing in the drinking water bag, the rustling of hair against the inner helmet, and the sound of music in the headphones. There is the noise of electricity, the hum of the life support system of the extravehicular suit, and the trembling sound of the superarm working.

These subtle movements are inaudible under normal circumstances, but they stand out against the silent background, blending together like a symphony that has failed to blend in.

Speaking of which, the universe itself is not silent. There is not nothing in the vacuum. It is actually filled with radiation, energy and particles that are invisible to the human eye.

From neutrinos, microwave background radiation, to ubiquitous energy fluctuations, and the ripples caused by gravity in space, if humans can perceive these things, then in the eyes of humans, the universe will be a boiling soup pot with background radiation It is the red bottom of the pot, and the fluctuations of quantum energy are the bubbles that rise and burst on the water.

The universe is like a radio station with no one speaking, full of noisy white noise all the time.

It turns out to be a noisy and anxious world.

Maidong stood at the end of the super-big arm, holding the lock of the safety rope in her hand. The white Eagle spacecraft expanded rapidly in her eyes, like an oncoming train.

At this time, only the upper stage of the Eagle spacecraft was left. The command module cargo compartment and rocket engine together were four or five meters long. Maidong saw the emergency escape hatch of the command module, which was a small circular hatch. , there are two doors on the left and right sides of the back of the Eagle spacecraft, used for emergency escape of astronauts.

Under normal circumstances, the crew enters and exits through the passage at the bottom of the command module, and when docking with the space station, the emergency escape hatch is generally not used-unless there is a fire in the cabin. These two hatches are connected to the body through explosive bolts. Once an accident occurs and the crew in the cabin issues an emergency escape command, the hatches will be thrown far away. In other words, these two doors cannot be closed when they are opened.

In the non-activated state, the emergency escape hatch is almost nailed to the body and is very strong, because this thing does not have any complicated opening and closing hinges and locking mechanisms. It is opened directly by explosion, which is simple and crude.

What Laomao wants is simplicity and crudeness. The lander has used its convulsive computer to prove that the more complex something is, the more likely it is to go wrong at critical moments.

Facts have proven that the simpler and cruder things are, the more reliable they are in more urgent situations.

There is a handle on the emergency escape hatch. After thinking about it, Old Cat thought that there were only two places on the Eagle spacecraft where the safety rope could be fastened - the edge of the docking port could actually be fastened with safety ropes, but Old Cat I doubt the docking port can withstand such a huge pulling force.

After the safety rope clasps the Eagle spacecraft, Lao Mao will tighten the rope, pull the lander, and reduce its relative speed to zero. This is like using a rope to forcefully stop a sliding rear eight-wheel trailer. , a huge pulling force will be generated in the process. For the sake of safety and security, the old cat must of course tie the rope to the winch or bumper instead of the license plate.

Laomao finally used the docking port as a backup option. If Ophiopogon japonicus failed to grab the emergency escape hatch, it would use the docking mechanism instead.

"Ten seconds." Lao Mao's voice sounded in Maidong's headphones.

Maidong slowly held his breath.

"Five seconds."

The Eagle spacecraft was within easy reach.

It is really counter-intuitive to witness such a big guy flying over silently. Maidong always subconsciously feels that something is pushing it.

The old cat stared at the screen closely.

It turned on the camera on the super arm, and the old cat could see the figure wearing the extravehicular suit, and he could also see the approaching Eagle spacecraft.

The lander is already very close.

But it's not time yet.

The relative speed between the Eagle spacecraft and the space station is six meters per second. This speed is too high. A lander weighing more than ten tons flies at a speed of six meters per second. The energy it carries is quite terrifying, and Not to mention a direct collision, even a scratch would be unbearable.

The train has not yet arrived at the station, and the old cat is waiting.

It's waiting for the lander to enter the great circle, a great circle with a radius of seventy meters - the range of motion of the superarm.

"Three seconds!"

The Eagle spacecraft passed by Mai Dong's eyes, just like a locomotive rumbling past the passengers waiting on the platform.

The train is coming into the station!

"The arms are set to the same length! Start rolling! Countdown to five seconds——!" The old cat slammed on the keyboard and shouted loudly, "Ophiopogon japonicus——!"

The super big arm received the command and the gyroscope stabilized the attitude! Motors and motors on! It was like a rocker used to set up a camera when filming a movie. It began to move in the same direction close to the Eagle spacecraft. The direction was locked, and the moving line was a very strict straight line. In the next five seconds, Ophiopogon japonicus and the Eagle spacecraft The relative speed of the spacecraft is zero!

Maidong leaned forward and struggled to reach out to the shell of the lander - the emergency escape hatch was right in front of her, so close that she could reach it at her fingertips. As long as she grabbed it, she could grab the Eagle spacecraft and her own destiny. !

The girl suddenly froze.

She couldn't touch the Eagle ship.

She couldn't reach it.

Ophiopogon japonicus's hands were shorter, and there was still a small error when measuring distances and angles. The error was only an insignificant five centimeters. Under normal circumstances, this is completely understandable. After all, humans are not machines, and a small error is harmless.

But at this moment, there is only five centimeters between Maidong's hand and the Eagle spacecraft.

Sometimes there is only five centimeters between life and death.

The super arm moves synchronously with the Eagle spacecraft. They move within this large circle with a radius of seventy meters. The big arm will soon be unable to keep up with the speed of the lander. The synchronization time between the two is only five seconds.

How long is five seconds?

The lungs can relax twice and inhale 600 milliliters of air.

The heart can beat five times and pump out 375 milliliters of blood.

The brain can imagine the voice, face, and smile of a loved one, and then directs the hypothalamus and pituitary gland to secrete dopamine.

Sound can travel 1,500 meters.

The earth can move one hundred and fifty kilometers.

Light can travel 1.5 million kilometers.

The universe can expand 1.5 million light years.

Five seconds in the universe is enough for the birth of ten thousand stars, and five seconds for one person is enough for him to fall in love with another person.

Or make a decision.

How many decisions in this world that can change history are made in five seconds?

"Mr. Cat!" Maidong yelled through gritted teeth, "Unlock the platform!"

The old cat was taken aback, and without saying a word, he immediately unlocked the lock and said, "Unlocked!"

The girl clutched the safety rope tightly and used all her strength to leap toward Mars, toward the vast deep space, and toward the Eagle spacecraft!
