Chapter 2927 Hold Your Breath
The mimicry experiment started soon, and the shadow of the spaceship appeared on the big screen in the laboratory.
Then the spacecraft rose higher and higher, and soon entered the predetermined orbit.
At this moment, everyone held their breaths.
The spacecraft enters the predetermined orbit, which is the prerequisite for the orbit change experiment. If this step is not achieved, then let alone the active orbit change, the whole experiment will be a failed experiment.
1 minutes, 2 minutes, 3 minutes...
"The spaceship has successfully entered the predetermined orbit." A crisp boost sounded in everyone's ears.
Track access successful!
Qin Luo squeezed his fist excitedly. Although he had expected it, when he saw it with his own eyes, Qin Luo still couldn't contain his inner excitement.
It went to the sky very successfully and successfully entered the predetermined orbit. From this perspective, China's manned spaceflight has taken a big step forward!
"Professor Zhou, when shall we start the next experiment?" Qin Luo turned to look at Zhou Minggang.
"According to the speed of our spacecraft, it should take about 1.5 hours to orbit the Earth." Zhou Minggang said, "And the perigee will appear in 2 hours."
"The spaceship will enter the active orbit change program in 1 hour and 50 minutes and start orbit change!"
"Professor Qin should know that, looking at the experimental reports around the world, the success rate of orbit change at the perigee is the greatest."
Qin Luo nodded, indicating that he understood.
Indeed, as Zhou Minggang said, when the orbit is changed at perigee, the gravitational force of the earth is the greatest, and it is also the best place to implement the orbit change.
This point has been verified by countless experiments in the world.
In this way, after more than an hour of smooth operation, the spacecraft began to decelerate. At this time, the centripetal force provided by gravity was greater than the centripetal force required for circular motion, so the spacecraft moved centripetally, and the orbits became elliptical.
When it reaches 2, because the distance between the spacecraft and the star becomes smaller, the gravitational force (centripetal force) becomes larger, and the spacecraft gradually descends towards the low orbit.
The active track change has officially started!
At this moment, everyone including Qin Luo held their breath.
They know that now has ushered in the most important moment. Once the spacecraft enters a low orbit, it can use the gravity of the earth to successfully land.
1 minutes, 2 minutes, 3 minutes...
Time passed by every minute and every second, and ten minutes passed in the blink of an eye.
Just when everyone thought the experiment was going to be successful, an accident happened suddenly.
I saw the spacecraft trembled violently, and then flew towards a high-dimensional orbit like a kite with a broken string.
At this moment, the entire laboratory was silent.
Whether it was only Qin Luo, Zhou Minggang, or anyone in the laboratory, they all lowered their heads at this moment and remained silent.
The experiment failed again, and on the basis of the previous failures, complete preparations were made.
Sure enough, manned spaceflight is the brightest pearl in the history of human development, and it really is not so easy to succeed!
Qin Luo smiled slightly, forcibly lifted his spirits, and clapped vigorously: "Papapapa~"
The huge applause, like bursts of thunder, directly shook everyone's heads.
They couldn't figure it out, the experiment had failed, why Qin Luo still applauded.
Is he not sad at all?
"Professor Qin, who is this?" Zhou Minggang frowned slightly, and looked at Qin Luo with some doubts.
