Physical training doesn't have any strange equipment, but the intensity makes many people feel that basic rocket physics and space flight engineering techniques don't seem so boring.

Different from the previous theory class, this time the strong man named Anthony performed the best, the bench press and clean and jerk were the first, followed by Zhang Heng, and the young man who looked weak was ranked third.

The performance of high school students is not satisfactory, and he is still behind the middle-aged man who looks like an intellectual, but considering that he should be about to take the college entrance examination, it is not incomprehensible that the study task is repeated, even if he wants to exercise more, I am afraid that he will not have time.

In addition, the bottom is still fat, and his performance seems to prove once again why he was kicked out of the original team, and I don't know where he got his pride before, pull-ups can only do half of it and dare to let Zhen Kuang go first, but fortunately, Zhen Kuang still insisted on choosing the last one to enter the gym, but soon she regretted it.

Although she didn't have to participate in this training because of her broken foot, the captain said that he would spread the amount of training owed this time into the subsequent training, and Zhen Kuang was not idle after that, and the lower limbs could not be exercised but the upper limbs could be exercised.

After all the training content was tossed, it was already 11:50 p.m., and the seven people dragged their tired bodies and even more tired brains back to the conference seat upstairs again, and began to study non-stop flight lessons, because they were not Air Force pilots before, and according to the captain's requirements, they needed to board the T-38 trainer plane within a week to familiarize themselves with the flight.

This time, all players, including Zhang Heng, were completely exhausted.

Fortunately, the accommodation environment prepared by NASA for them is not bad, not only everyone has a room, but also the toiletries and changes of clothes are very complete, according to the usual Zhang Heng will check his character panel at the beginning of each new copy, but when he opened the door of his room at 2:15 in the morning, he didn't want to do anything except fall on the sheets.

Three and a half hours of sleep can't completely relieve mental and physical exhaustion.

But the alarm clock at the head of the bed still woke Zhang Heng up from his sleep on time, and he took a cold shower in the shower room in the shortest time, and then opened the curtains, so that he had time to take a look at the room he was in.

Zhang Heng doesn't know what other people are like, the overall area of his room is not too big, about forty square meters, but the furniture inside is readily available, including a single bed, a wardrobe, a writing desk, a sofa and a TV refrigerator and other things, it is worth mentioning that there was already a color TV in the sixties, of course, it is still a love action movie quality, and the digital TV of later generations cannot be compared, the appearance is also a little peculiar, it is actually square, with a thick frame, It's more like a microwave oven or an aquarium or something.

And on the wall behind the TV, there is also a poster of Elvis Presley, which should be from the song and dance romance movie "Pink World" starring him and Ann Margaret, and the two of them make backward movements towards the camera together.

Zhang Heng took out another clean NASA uniform from the closet and put it on, and also saw the note in the basket below - leave the clothes you need to change here.

Zhang Heng just left the previous uniform inside according to the note, and before he could check what was in the refrigerator, the captain's voice sounded again outside the door, "Assemble, I'll take you to visit the space center, eat at six twenty, and then start spacesuit training at half past six." ”

After the first day of torture, the players have been mentally prepared for this tight schedule, but they have not reacted much, of course, it may also be because they have not woken up or have become insensitive, only the high school students have a little anticipation on their faces when they hear the spacesuit training.

The spacesuit used in the Apollo mission was an upgraded A7L spacesuit based on the Gemini spacesuit, and there were improved versions for the later Apollo-Soyuz missions and Skylab missions.

Astronauts can often be seen in science fiction movies quickly putting on and taking off their spacesuits, but in reality this is simply not possible.

Taking A7L as an example, this spacesuit weighs nearly seventy pounds, including five main layers, a liquid cooling suit close to the skin, which is the innermost part worn by Zhang Heng, followed by a layer of nylon to ensure comfort, nylon is placed on a pressure airbag to facilitate the movement of joints, and outside the airbag is another layer of nylon, which is used to fix the airbag, and finally there is an outermost layer of mask, which is worn outside the pressure suit for heat insulation and protection, and the helmet and gloves are connected to the pressure suit through a closed metal ring.

And that's not all, Zhang Heng has to carry a portable life support system behind his back to provide oxygen that can be breathed after leaving the cabin, as well as a cooling function, and a VHF antenna on the upper left to support two-way voice communication.

This is also the reason why astronauts need good physical strength, the vast majority of ordinary people can't move at all after this set of things on board, of course, it will be much better after entering space, this kind of spacesuit NASA has prepared three sets for each person, one for the mission, one for training, and one for backup.

Zhang Heng put on the famous "fish tank" helmet with the help of the trainer, and the world suddenly seemed to be isolated at the other end, but the helmet was not completely quiet, he could hear a comfortable humming sound, as well as the sound of the fan turning, from the life support system.

The trainer helped Zhang Heng learn how to use the urine bag, and read the life support system control unit on the chest, where the liquid and electrical energy in the portable life support system can be monitored and regulated.

This is a very new experience for the seven people present, although it is still hard, but compared with the boring pure theoretical learning and high-intensity physical training, spacesuit training can undoubtedly bring a little fun.

In fact, if it weren't for the brutal survival pressure hanging over their heads, for 99.9999......% of the world's people, becoming an astronaut and riding Apollo 11 to the moon is an unprecedented extraordinary experience, you must know that in 2001, a wealthy American man paid a total of 20 million US dollars for a seat on the Soyuz in order to become a space tourist, in exchange for 8 days of sightseeing on the International Space Station.

However, Zhen Kuang noticed that Zhang Heng's eyes always fell on the clock not far away, intentionally or unintentionally, during training breaks, and he seemed to be waiting for something.
