"Uh, did any of you see my gloves?" Collins came out of Zhang Heng's side like a ghost holding a bowl of pork with baked potatoes that had not yet been hydrated.

"I don't know, but it seemed to float over my head a quarter of an hour ago." Zhang Hengdao.

"Did you just watch it fly away?"

"It seems so."

"Okay."

"You can go to the lunar module and see that it must have drifted in that direction."

"Collins, did you get the wrong toothbrush?" Armstrong also leaned over at this time, and said with a serious expression.

"Is there one? I obviously put my name on it. ”

"Yes, and you stuck it on my toothbrush." Armstrong paused, "Also, remember to clean the fuel cell, who's going to clean up?" ”

Zhang Heng raised his hand, "It's my turn." ”

"I'll do it anyway." Collins said, "You still have big things to do today, don't you?" After speaking, he patted Zhang Heng's shoulder again, "You must come back safely." ”

"Don't worry about me, Neil will come back safely." Zhang Hengdao.

Collins frowned, a little unsure of what Zhang Heng meant by this.

But at this time, the voice of the ground control center also came from the radio communication system, "Apollo 11, this is Houston, and you will enter the orbit around the moon in a quarter of an hour, and the call is over." ”

"Roger, Houston, we'll be ready, done." Armstrong said, then turned his head to Zhang Heng and said, "You haven't eaten breakfast yet, eat more, we have a lot of work to do after landing on the moon, and time will be very tight at that time." ”

Zhang Heng nodded, but he knew very well in his heart that he would not stay on the moon for too long, Zhang Heng looked down at the starfish in his hand again, there was only one minute left until 5:55, according to the time flow rate of reality and the copy, that is to say, he only had 4 hours left in this world.

That's why he told Collins that Neil would come back safely, and that he wouldn't step into the command/service module again once he left.

Twenty minutes later, all three of them suspended their work and came to the porthole, which happened to have a relatively clear field of vision and could see the surface of the moon, and the current Apollo 11 was only more than a hundred kilometers away from the lunar surface.

The Moon itself does not emit light, but it can reflect about 7% of visible light.

Through the porthole, the three of them could see the undulations and ravines on the surface of the moon, like the surface of a beehive, which Zhang Heng knew was plagioclase, a volcanic rock formed by the cooling of magma, which formed the lunar crust, while the moon mantle was made of stronger basalt, which had more iron than the mantle, and the innermost lunar core was melted iron, containing small amounts of sulfur and nickel.

"Well, that looks like we're heading." "We're going to part soon, and I hope you won't miss me too much," Collins said. ”

"Thanks, Michael, you can eat all the chicken salad while I'm away." Zhang Heng replied.

"I'm not going to take that as a joke." Collins pretended to think seriously for two seconds before saying, "You two take care, I'll be waiting for you here, and we'll go back to Earth together." ”

Armstrong remained as silent as ever, and just nodded.

Zhang Heng used the last time to prepare for the month, gave up those daily necessities, only brought the game props with him, put on the spacesuit, and then he and Armstrong entered the lunar module "Eagle", and Armstrong closed the hatch.

"Houston, this is the Eagle, David and I have entered the lunar module, the weight-bearing legs have been extended, and we are in good condition, and we are done."

"Eagle, this is Houston, please make sure your spacecraft is powered by ethylene glycerin line 1."

"This is the Eagle, we're on Line One, over." Zhang Hengdao.

At this time, the voice of Collins also came from the communicator, "This is the Columbia in the command/service module, all 12 pairs of latches are sealed, and then I will turn on the manual mode, and it is expected that the Eagle will be separated in twenty minutes." ”

"Roger."

"Good luck to you."

In order to reduce the weight as much as possible, there are no seats in the lunar module, Zhang Heng and Armstrong stand in front of the control panel, as the pilot of the lunar module, Zhang Heng will take on the main driving task next, he needs to drive the Eagle to land smoothly at the designated place.

This will be a challenge for him, but the more times like this, the calmer Zhang Heng's heart will be.

Armstrong was originally a little worried that Zhang Heng's training time was too short, but when he saw the latter's eyes, he knew that Zhang Heng was ready.

"OK, we're going to get started." After the countdown, Collins pulled the joystick, allowing the command/service module and the lunar module to complete the separation.

"This is Houston, please stay flying, Eagle, watch your fuel, continuous ignition time is up to 910 seconds."

"Roger, Houston." Zhang Heng carefully controlled the lunar module to land on the surface of the moon.

However, it didn't take long for them to run into trouble, and the alarm light on the dashboard suddenly flashed.

"The computer is overloaded, we lose the radar." Zhang Heng glanced at the indicator light.

"Roger, Eagle, please choose where to land."

"Roger, Houston." Armstrong replied.

But before the two of them could breathe a sigh of relief, another warning light came on the dashboard.

"Program alert," Zhang Heng frowned, "Error code 1202, what is this Houston?" ”

"1202, Roger, we're checking, Eagle."

Zhang Heng manually turned off the alarm, but less than half a minute later, another program alarm sounded, and at the same time, the altimeter also stopped at 4,000 feet and no longer worked, which meant that Zhang Heng could only land with the naked eye.

Things started to look bad, but the two had no other options at this point, and when they landed at about 2,500 feet, Zhang Heng and Armstrong realized that they had strayed from their target.

However, the real killer was the failure of the fuel meter next.

When Zhang Heng confirmed it for the last time, the remaining fuel of the propulsion system could still be ignited for about thirty seconds, and a huge deep valley appeared in front of the Eagle, and the radar failed, Zhang Heng didn't know how wide the deep valley was, and he didn't know what its depth was.

He needs to make a decision in the shortest possible time, whether to risk a forced landing in front of the deep ravine, or find a way to fly over the deep ravine in front of him.

And at this critical juncture, the wireless Bluetooth headphones of the AirPods that Zhang Heng and those game props put together suddenly started by themselves.

A familiar voice came from the communication channel, "Friendly reminder, you still have 23 seconds of fuel." ”
