The Pioneer spacecraft is launched directly from the ground, so the spacecraft is attached to the launch stand in an upright position, enters the inner compartment of the spacecraft, and comes to the bridge position, that is, the cockpit needs to rely on a special gangway to climb up, and then fix the body in the seat at 90 degrees.

As the captain, Su Yichen's seat is in the center, and on the right-hand side is the assistant position, which is held by astronaut Lin Guodong, who has worked on the International Space Station and Tiangong-1 and is an experienced veteran astronaut.

On the left hand side of Su Yichen is the standby astronaut Mo Liwen, as a standby astronaut does not mean that Mo Liwen's ability is not enough, mainly because Mo Liwen's space stay time is slightly shorter than the previous candidate, so he was brushed down as a reserve candidate, who would have thought that such a thing happened temporarily, Mo Liwen, who thought that he had no chance, was ready in the shortest possible time after receiving the emergency order.

Fortunately, Gu Chen, the astronaut in charge of medical care on the Pioneer, did not have an accident, otherwise the launch of the Pioneer would not have been postponed. Gu Chen's importance in the Pioneer is second only to Su Yichen and Lin Guodong, and he mainly plays the role of the Pioneer's doctor, and is also responsible for some research work on creatures, animals and plants in space.

Gu Chen and Gao Jian's position was at the back, and their job was basically just waiting when they took off. Opening the control platform, Su Yichen first connected to the communication of the base center and made the final preparations.

"Vanguard, please note that the last 30 minutes before takeoff are ready."

"Pioneer received, last 30 minutes to take off and prepare."

Su Yichen replied, and at the same time switched communication, assistant Lin Guodong temporarily maintained communication with the base center, and he contacted the spaceship's intelligent core, that is, Su Li.

"Su Li, report on the overall situation of the spaceship."

"The spacecraft self-test is intact. The controllable thermonuclear fusion engine is normal, and the auxiliary power rocket is normal...... Ready for takeoff. Due to Su Yichen's request, Su Li did not show humanity as usual, but reported step by step.

"Monitor at all times to make sure it's correct."

"Understood."

Su Li replied simply and concisely, and Su Yichen finally confirmed the situation of Luo Yan's hibernation device. Luo Yan's hibernation device is placed in a special cabin of the Pioneer, although it is very safe and reliable, but after all, uncertainties may arise at any time during the launch, and he must be foolproof.

Thirty minutes passed in the blink of an eye, and the personnel in the center of the base were fully prepared, and everyone was glued to the big screen for the upcoming launch of the Pioneer spacecraft.

“29…… 28…… 27…… 26……。 ”

The emotionless electronic countdown reminds everyone that the final launch is approaching, and when the final number returns to zero, the auxiliary power rocket ignition begins. The Long March 7A launch vehicle bundled with the Pioneer spacecraft began to ignite, and the launcher was ready to separate.

The ground shook slightly, and a large cloud of smoke and dust was sprayed from under the Long March 7A carrier rocket, which shrouded the area of nearly 100 meters around the launch frame in just a few tenths of a second, and then a little flame light at the tail of the rocket lit up, which became brighter and brighter, and the entire Pioneer spacecraft began to take off, and the flame light at the tail of the rocket stretched longer and longer in the night sky. The smoke and dust below churned like clouds swept by a storm, and in the blink of an eye, the Vanguard made a striking mark against the night background and rushed into the sky.

Tian Lao's eyes were firmly fixed on the Pioneer's flight. Whether it is a rocket launch or other spacecraft launches, including the current Vanguard, this is the most dangerous time. In that year, the Americans' space shuttle Challenger failed to take off, and the tragic destruction of the guide plane and the death of people occurred, which was only a dozen seconds after the ignition and launch. When witnessing the Pioneer ignite and take off. Tian Lao's heart was lifted, he couldn't help but clench his hands, and even held his breath as he watched the Pioneer flying into the air with a scorching tail flame on the big screen began to change its intended direction.

"Turn to normal!"

"Auxiliary power rocket feedback is normal!"

"Acceleration is normal!"

"The engine of the first stage of the power rocket is ready to shut down and separate ......."

"The shutdown separation is complete, and the second node is fired...... Ignition is normal! ”

"Altitude control zhì normal ......."

The whole control zhì center. The staff continued to report the situation of the Pioneer after liftoff, and lifted to a certain height, that is, about 100 seconds after the launch of the Pioneer, about 70 kilometers above the ground, at this time looking up at the sky with the naked eye, it was still possible to clearly see that the first engine of the tail section of the Pioneer auxiliary power rocket that had become a small bright spot was shut down and separated, and at the same time the second section of the rocket began to ignite, and the two eye-catching dots one gradually dimmed and fell, while the other became brighter and brighter. With the Pioneer spacecraft, it continued to go into space with extremely high acceleration.

"Section 2: Preparing for Shutdown and Separation...... The separation is normal, and the third node fire is normal ....... ”

When the second section separated, the naked eye could no longer see the Pioneer in the dark night, but the operation status of the Pioneer could still be seen on the large screen in the center of the base. As an auxiliary power rocket, it is not that the more sections it has, the better, but the average person always feels that the more sections it has, the greater the propulsion capacity of the rocket, and at the same time, it can also run for a longer time. This view is actually wrong, because don't forget that every time each section of the rocket is shut down and separated, it must face the problem of re-ignition of the next section, and once the number of rocket sections is increased, each additional section will increase various uncertainties and possible failures in flight, and these problems are geometrically increased according to the calculation of probability.

The Long March 7A launch vehicle used by the Pioneer is currently the most advanced and reliable rocket in China, due to the large hull of the Pioneer and the required acceleration requirements, the Long March 7A launch vehicle has only three sections, these three rockets will provide the Pioneer to propelle to the near-Earth space orbit, and when it reaches a certain altitude, the last rocket will automatically shut down and separate, and then the Pioneer will start its own controllable thermonuclear fusion engine to continue to accelerate away from the earth's gravity and fly into space.

"The predetermined orbit has been reached, and the third section is ready to be shut down and separated...... The separation is normal, and the Vanguard engine starts...... The engine starts normally! The engine starts normally...... Pioneer has broken through low earth orbit! Breakthrough in low earth orbit! Acceleration is normal! Acceleration is normal! ”

When the final rocket was shut down and separated, Vanguard's controllable thermonuclear fusion engine began to start, and after a qiē showed normal, there was a cheer from the center of the base, indicating that the Pioneer had been fully launched. When the Pioneer controllable thermonuclear fusion engine was activated 10 seconds later, the exterior of the Pioneer spacecraft flying away from the Earth's near-Earth space orbit began to rotate, and the base also received an echo from the Pioneer.
