Tang Fengzhi is not too worried about safety issues, because the Americans are the most experienced in the world in landing on the moon.

So far, humans have successfully landed on the moon six times, all of which were done by the Americans, and a total of 12 humans have left footprints on the moon. From Apollo 11 in 1969 to Apollo 17 in 1972, except for Apollo 13, which returned to Earth early due to an accident in the spacecraft, the other six Apollo spacecraft have sent astronauts to the surface of the moon.

Later, although the Apollo program was too expensive for the Americans to stop the program, it is undeniable that the Apollo program gave the Americans the experience of landing on the moon that the rest of the world cannot match.

Compared with the Apollo program more than 40 years ago, human technology is now more advanced, the performance of the spacecraft is more stable, and the possibility of an accident like Apollo 13 is very small.

Now the most likely process to go wrong is at the stage of rocket liftoff. After all, when the huge "Starry Sky One" carrier rocket lifts off at full capacity, it carries several thousand tons of fuel. These fuels are even more awesome than antimony, and in the event of an accident and an explosion, the consequences are unimaginable.

However, Dr. Schmitz also made a very bold innovation about the safety of the rocket during liftoff, and after simulation experiments, this innovation can greatly improve the safety of astronauts.

Unlike the construction of a lunar spacecraft and a lunar lander in geosynchronous transfer orbit, the "Starry Sky No. 1" carrier rocket at that time was launched at full capacity every time it was launched, and it was necessary to carry various components of the lunar spacecraft and lunar lander and fuel into space, so naturally the load of the "Starry Sky One" carrier rocket could not be wasted.

But those things are inanimate things, although they are worth a lot. But even if the launch fails, it can withstand it. But if there is an accident in the process of manned liftoff of the "Starry Sky One" carrier rocket, resulting in the death of astronauts, especially if there is a Tang Feng on it, then the problem will be big.

It was based on this problem that Dr. Schmitz introduced catapult technology on the Star-1 launch vehicle for the first time. to ensure the safety of the functional compartment where the astronaut is located.

Because the launch of the "Starry Sky 1" only sent six astronauts to the lunar spacecraft in the geosynchronous transfer orbit and had no other payload, the payload capacity of the "Starry Sky 1" carrier rocket has a huge surplus. Moreover, the astronaut's functional chamber is located under the fairing at the top of the rocket, and there is a second-stage rocket separated from the first-stage rocket, so Dr. Schmitz specially installed a set of ejection devices for the manned launch vehicle.

It's as if a fighter pilot can pull the ejection device under the seat when the plane encounters an uncontrollable situation, allowing the pilot to escape. Dr. Schmitz also installed such a set of catapult devices with more powerful ejection between the manned functional compartment and the three-stage rocket.

This ejection device is completely automated, and the control program of the ejection device is controlled according to six high-sensitivity detectors installed in the fuel compartments of the first and second stages of the rocket. Whether it is a first-stage rocket or a second-stage rocket, three high-sensitivity monitors are installed in the fuel tank, once the fuel tank changes drastically, such as temperature and pressure changes, as long as it exceeds the detection range of the detector, then the detector will be within one hundredth of a second. An alarm is sent to the control system of the ejection device, and when the alarm is received by the control system. It will also eject the manned functional compartment within one hundredth of a second.

This strengthened catapult device weighs three tons, that is, because the "Starry Sky No. 1" carrier rocket has a huge surplus of load when it is carrying out manned liftoff, so this set of catapult device can be installed. Otherwise, this thing will not be applied to launch vehicles at all.

However, this device can eject a functional compartment weighing four tons out hundreds of meters in a very short time, coupled with the inertia of the functional compartment itself, so even if the rocket explodes, it is enough to ensure the safety of the astronauts in the functional compartment.

That is, Tang Feng is rich. to be able to carry out an additional launch for the sake of safety in such a big way. If it were NASA or other countries' space agencies, every time the rocket was launched, those experts would like to squeeze the load of the launch vehicle to the extreme, where would the surplus load make the rocket install such a heavy catapult device.

Of course, this catapult also has anti-mis-excitation measures, a detector warns, the catapult will not operate, only two or more detectors at the same time to warn, the catapult will carry out the operation, the function chamber ejection out.

With the existence of this thing, unless all six monitors fail, Tang Feng and them will hardly have safety problems.

Once in space, then there is no problem, don't forget, there is still a Nautilus parked in Tang Feng's star core space, in case something really happens that cannot be saved, the Nautilus will become Tang Feng's lifeline

However, with Dr. Schmitz and the current technology, the possibility of a catastrophic accident on a lunar spacecraft with a collection of top technology is very small unless someone deliberately sabotages it.

It is precisely because of this heavy insurance that Tang Feng is very relieved to prepare to enter space. In fact, with current technology, there is almost no difference in safety between going into space and flying from Asia to North America by plane, it is just a matter of flying a little higher

Tang Feng was trained in the astronaut training center with peace of mind, and he was absolutely no problem in terms of physical fitness, even the physical fitness of the other five astronauts could not be compared with Tang Feng. He just wanted to learn some other knowledge now, after all, after going to space, the six of them worked together together, and mastering a little more things would also be helpful for the entire moon landing operation.

But even so, Tang Feng watched the last launch of the "Xingkong-1" carrier rocket in Cape a week later, this time to send 21 tons of fuel and some supplies to the lunar spacecraft. When the refueling module and the lunar spacecraft are successfully docked, the fuel will be automatically injected into the fuel tank of the lunar spacecraft and the lunar module under the control of the program, and all the fuel will be replenished for the two big guys.

As for the supplies, they will also be carried by the robots parked inside the lunar spacecraft according to the program.

I have to say that the current technology is much more powerful than a few decades ago, not to mention anything else, the robot in the lunar spacecraft alone is far from being comparable to the Apollo program back then.

With the last successful launch and successful recovery of the Star-1 launch vehicle, the time is getting closer to the start of the actual moon landing (to be continued). )
