Tang Chao wants to sit on Mars, and the materials carried by that landing craft are not enough.

The manned module of the Mars lander can be used as their temporary living place, it has food, water, toilets, etc., and some seats can be turned into beds, and if you can't do it, you can go to the pressurized cargo compartment to sleep in a hammock.

All of these things add up to 6 of them to stay on Mars for 10 days.

In other words, they have to find a suitable base construction site in 10 days, and then land the living module to build a base.

If they can't find it, then they can only land another landing craft and "recharge" their temporary residency.

Add another 10 days, and if 20 still can't find a suitable base construction site, then they will have to retreat to the task of building a permanent base to establish a temporary base.

It's not that the spacecraft doesn't have enough supplies to temporarily consume for extended time, but because the chemical fuel they carry is limited.

In order to make the Spore spacecraft as compact as possible, they did not carry extra giant hydrogen and oxygen fuel tanks, so the hydrogen and oxygen fuel they carried were limited, so that the two Martian landing craft could only land and take off once, and the two Martian survival modules could only land once each.

Of course, the establishment of a temporary base does not mean that it will be abandoned after one use, but astronauts and scientific researchers will not be permanently stationed here, let alone develop a "Martian city" here.

Their role is like the relationship between human society and Antarctic research stations, although they cannot live for a long time, they can be used for scientific research.

The astronauts spent most of the day in the alien camp and returned to the landing craft in the afternoon.

This is the first time that humans have come into contact with aliens, and although the aliens are unexpectedly peaceful, it is the first day after all, and the two sides have limited understanding, so they still have to try to refrain from it.

And something is not right, there are big differences from the various mission plans discussed before, so they also need to go back and communicate with the other side of the earth.

Not only do they have to adjust their plans, but the little green men have to trim them up.

When they left, the little greens took off their helmets and stepped off the big mechs.

"Whew~ It's so tiring to play with the BOSS, it's all live, you can't be wrong at all."

"Of course, this is not the same as our experience of filming, there can't be the slightest NG shot, it must be passed."

"I feel that my performance this time is not bad, Bill, you are too nervous, fortunately you said that half of the time was changed to Kanxing language, which humans do not understand, pretending that Chinese has not been learned well."

"Captain, do you think I'm qualified for this performance? Can you get a Cansca little green man back to Canstar? ”

Linus smiled and nodded, "Everyone's performance this time is good, but there is still room for improvement, Valentina, I just noticed that your big mecha's right arm is out of order, obviously it wasn't repaired before, and if you fix it again, you can't do it again tomorrow." ”

"Bill, you're too nervous, if there is someone else next to the boss when you meet later, you can just say Kanxing language, and the boss can understand."

"Bob, you're not bad, but you're just too open, if it weren't for the fact that we're different from the human race, they'd definitely see that you're acting, so you'd better keep it in the back."

"That's it, what to do, rest after you're done, and I'm going to continue acting with the boss tomorrow."

"Okay, Captain."

The aliens are quiet here, but Tang Chao's side is very lively.

Back in the manned capsule, several people disarmed their power armor, took turns to go to the toilet, and then began to contact the other side of the earth.

Because of the delay problem, they will also discuss it themselves when they are waiting for information, but basically it is said by other people, Tang Chao listens, and occasionally says a word.

Compared with Tang Chao, others are really thinking about problems.

Since this contact with the aliens was very smooth, there was no fighting, so that some of the tactics they had prepared before were useless, and they just listened to the aliens speak Chinese.

Especially the fact that aliens speak Chinese really shocked them for a whole year.

It's a good thing that humans can communicate with aliens, but it's not a good thing that aliens know the language of humans, but humans don't understand the language of aliens.

Some of the initiative must be in the hands of humanity, so learning the language of the aliens is on the agenda.

There is also the matter of learning alien technology, they have carefully observed the alien spaceship, the alien spaceship is indeed more advanced than the human spaceship, just look at the original materials of the spacecraft and the human equipment materials used for later repair.

Although none of them are materials scientists, as astronauts, they deal with aerospace equipment every day, and they still have that bit of eyesight.

They also saw some symbols in the spaceship, if nothing else, it should be alien text, and if they want to learn alien technology, the text must be an obstacle.

Although aliens can speak Chinese, it is still the same sentence, the initiative must be in their own hands, so alien languages must be learned.

The good news is that through their observations, they found that the alien tech tree seems to be very similar to the tech tree that humans walk, and it is not the weird "alien tech tree" in science fiction movies, which should be more friendly to human learners.

Half of the astronauts who came this time were "combatants", and the scientific research and engineering personnel were geological and mechanical, so they had no say in the extraterrestrial environment, biology, chemistry and the like.

At the same time, the ground is also holding a meeting to discuss whether to let Tang Chao bring the aliens back as soon as possible, instead of on Mars.

Although Tang Chao said before why he stayed on Mars, some people said that it was not a problem, and after bringing the aliens back, he went directly to the scientific research institute, and he usually saw scientists and engineers, and no one could disturb them.

As long as the aliens are brought back, then it will be much easier for human beings to act, the information will not be delayed, and some key academic information will not need to be conveyed by laymen.

For this matter, the people on the earth obviously thought a lot, and they thought about it very thoroughly, Tang Chao was noncommittal about these things, but he also had his own plans, so it was impossible to go back so quickly.

So he said yes.

But in the end, I still have to ask the opinion of the aliens.

If the two sides really fought, and Tang Chao also killed or captured these four aliens, then it was naturally up to him to decide what to do.

But now that the two sides are not at war and have communicated smoothly, then the human side has to consider normal diplomatic relations.

Or the diplomatic relations between human civilization as a whole and extraterrestrial civilizations.

The key is Mars, although Mars is a planet in the solar system, Mars does not belong to humans, and even according to the "first come, first served" statement, aliens can land on Mars earlier than humans.

————

Therefore, if you want the aliens to move the place, you must consult with the aliens.

A busy day passed, and as soon as Tang Chao and the others arrived at the alien camp the next day, the aliens gave them a big gift.

"I heard that you are looking for a suitable base construction site, and it just so happens that we have fully explored the surrounding area during this time, and I think this resource marker map can help you."

As he spoke, Linus handed a tablet to Tang Chao, with resource marker information within five hundred kilometers of the surrounding area.

The others were stunned and thought, "Good guys, are aliens really coming? Is it really a win-win cooperation?"
