Become Top Student In A Second
Chapter 2927
The mimicry experiment started soon, and the shadow of the spaceship appeared on the large screen of the laboratory.
Then the spacecraft rose higher and higher, and soon entered the scheduled orbit.
At this moment, people hold their breath.
The spacecraft enters the predetermined orbit, which is the premise for the start of the orbit change test. If this step is not achieved, let alone the active orbit change. The whole experiment is a failed experiment.
One minute, two minutes, three minutes
"The spacecraft successfully entered the scheduled orbit." A clear rising tone sounded in everyone's ears.
Rail access successful!
Qin Luo clenched his fist excitedly. Although he had expected it, when he saw it with his own eyes, Qin Luo still could not contain his excitement.
It's a great success, and it has successfully entered the scheduled orbit. From this point of view, China's manned space flight has made a great stride 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 go around the earth." Zhou Minggang said: "and perigee will appear in 2 hours."
"The spacecraft will enter the active orbit change program in 1 hour and 50 minutes, and start the orbit change!"
"Professor Qin should know that throughout the world, the success rate of the perigee maneuver is the highest."
Qin Luo nodded, indicating that he understood.
Indeed, as Zhou Minggang said, the earth's gravity is the largest when it changes orbit at perigee, which is also the best place to implement the orbit change.
This has been verified by numerous 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 is greater than the centripetal force required by circular motion. Therefore, the spacecraft makes centripetal motion, and the orbits become elliptical.
When it reaches 2, due to the smaller distance between the spacecraft and the star, the gravitational force (centripetal force) becomes larger, and the spacecraft gradually drops toward the low orbit.
Active orbit change is really the beginning!
At this moment, all people including Qin Luo held their breath.
They know that now has ushered in the most important moment, once the spacecraft into low orbit, then can use the earth's gravity, successfully landing.
One minute, two minutes, three minutes
As time goes by, about ten minutes have passed in a twinkling of an eye.
Just when people thought the experiment was going to succeed, an accident happened.
I saw the spaceship shake suddenly, and then like a broken kite, it flew toward high-dimensional orbit.
At this moment, the whole laboratory was silent.
At the moment, either Zhou Mingli's head or that of his lab is silent.
The experiment failed once, and on the basis of previous failures, we made complete preparations.
Sure enough, manned space flight is the most brilliant pearl in the history of human development, and it is not so easy to succeed!
Qin Luo smiles, forcefully raises his spirit and claps: "Pa Pa Pa Pa ~"
the huge applause is like bursts of thunder, which directly makes people's heads hum.
They don't understand why Qin Luo clapped because the experiment has failed.
Isn't he sad at all?
"Professor Qin, are you?" Zhou Minggang frowned slightly and looked at Qin Luo with some doubts.
Then the spacecraft rose higher and higher, and soon entered the scheduled orbit.
