After confirming that aliens were okay and would not engage in any armed confrontation, the Martian astronauts who landed changed shifts with the astronauts in the Spore floating in orbit.

After all, at the beginning, in order to prevent aliens from attacking astronauts, the astronauts who landed were basically armed with a greater value than the scientific research value, and now that it is safe, of course, the scientific researchers with a greater scientific research value must be replaced to raise the scientific research capability of the Mars base.

The aliens and the Merrikens are all gone, and they are not in a hurry to study the alien spaceship, so they all return by car.

After going back, Tang Chao went to report the situation to the Earth Command Center, and the others began to formulate the alien spacecraft research plan starting tomorrow, and at the same time chatted about today's events.

"We also received them to the highest standards, and they turned around and took the aliens away, which is really not a thing."

"That's it, I thought those two astronauts had the same lofty ideals as us, but I didn't expect that they were completely puppets played by politicians, and they could do whatever they wanted."

"Hey, in fact, they can't help it, let's not say a word, we are just lucky, we met a team leader like Mr. Tang, let's talk about how to study alien spaceships."

"Mr. Tang didn't talk to aliens in vain before, he has already compiled a rough technical outline, this time we have the real thing, the direction of the research should be very accurate, and there will be no crooked path."

"I found out that Merrican stole some dispensable things, and the large modules can't be removed, I can understand, but why hasn't the storage module that recorded all the information removed?"

"Doesn't this fully show that the aliens were coerced, it is estimated that the aliens fooled them, and they may also feel that it is enough to capture the aliens, after all, there are two scientists and an engineer among the four aliens, and Mr. Linus is also an assistant scientist to the chief scientist, so he should know a lot of scientific and technological information."

"The aliens were kidnapped, and it is not so easy to get them to cooperate, and now Mr. Tang is reporting the situation to the headquarters, hoping that the country will quickly unite with other countries to put pressure on the Merrican side......"

After a while, Tang Chao completed the report and told the situation to the earth.

There's not much to say, the main event is that Merrican kidnapped the aliens, and then the spaceship was basically completed and stayed.

It's what the aliens repaired before, and what they are basically the same now.

The Merricans didn't cause any more damage to the ship when they left, only dismantling a few small things that didn't matter, so it could be carefully studied by researchers up and down, back and forth, inside and out, which is a blessing in misfortune.

Telling Tianxia and the Navigator Joint Command Center is telling them that "it's okay to scare people".

Before the aliens return to Earth, they can also pull all the countries except Merrican together to scare Merriken, and they must not be allowed to "swallow" the aliens alone.

There are a few months to do this.

And he himself would take the Spore to pursue the Enterprise.

He himself knew that he would definitely chase it, and everything was under his control, but what he said to the ground was "hope to catch it", showing a certain pessimism, so that the "firepower" on the ground could be more violent.

It's just that when he goes, the scientific researchers on Mars will not have an emergency escape spacecraft, not only can they not leave the surface of Mars, but they will not be able to return to Earth.

Spore carried a total of two landing craft, the first for the first landing, and after establishing a base in the area provided by the aliens, the first landing craft brought the armed personnel back to the Spore, and then the second landing craft brought the scientists down.

Therefore, the second landing craft only has one take-off fuel, and the two landing craft only have this one chance to take off, and when Tang Chao leaves, the scientific researchers will not want to touch the Martian sky again in a short time.

...... in this regard The scientists didn't care.

There is a Martian environment and alien spacecraft for them to study, and there is no media, no politicians, no capitalists to disturb their research, and they wish they could do research here for a lifetime.

Compared with the two Merrican astronauts who have no dreams and ideals that they complained about, they have a lot of dreams.

Of course, Tang Chao, who has greater ideals, will not let them have no security here.

First of all, the two survival modules are the first guarantee, even if one survival module fails, there is another survival module that can be used, there is a survival module as a "foundation", and there is a powerful power spacesuit, which is enough for them to repair the other survival module.

And in space, another spacecraft is already on its way.

Previously, it was a "Mars probe", but because of the characteristics of the super ion thruster trial type, 32 tons of mass, and multi-functional module combination, it became an "unmanned Mars exploration spacecraft".

Yes, it is the exploration spacecraft carrying the "large Mars unmanned helicopter" and the "large Mars unmanned rover", although the cargo it carries has been messed up by aliens, but its propulsion module is still circling in Martian orbit, honestly waiting for the take-off of the sampling rocket.

Later, the manned Spore came, and the propulsion module of the unmanned exploration spacecraft could not be wasted like this, so Tang Chao let it return.

After returning to Earth's orbit, researchers and engineers modified it and replaced it with a more efficient solar wing in the orbital maintenance module of the Tianting Space Station, so that the power of the ion thruster could be increased to be higher, so that it could carry more cargo.

An unmanned probe to Mars was relaunched, or now an unmanned cargo spacecraft would be more appropriate, with an overall mass of 90 tons.

Yes, it's almost three times as much as before, and if it's in the Earth's environment, the thruster will definitely not be able to fly, but it's different in space.

There is almost no gravity and no drag in space, and with a little push, the object can keep flying forward.

The benefit of an ion thruster is this, it consumes very little "fuel", it can accelerate for a long time, and with enough time, it can propel the ship to a very fast speed.

The Navigator's thrusters are more sophisticated, and they can have a lot of thrust at the beginning, so even if there is only one thruster, even if the current position of Mars is not close to the Earth, it can still fly to Mars within two months.

What's more, with some modules of the Heavenly Court Space Station, the Navigator can also play bigger.

It is to load two liquid fuel thrusters onto the cargo ship, directly give the cargo ship a violent initial velocity, and when the speed comes up, they can break away from the spacecraft, use the rest and then slow themselves down, and then wait for the "space three jumpers" to pick up themselves by the way when they come to collect garbage.

After getting back to the orbital maintenance module, do a little maintenance, no problem, and continue to use it next time.

With a high muzzle velocity, the ion thruster re-opening not only saves fuel, but also reduces acceleration time, which is very useful.

The mass of 90 tons includes the dead weight of the propulsion module, a standard Martian landing vessel, and an orbital supply silo.

This supply compartment is very important, if there is an accident at the base, the astronauts can take a landing ship to Mars orbit, and they can use the supplies in it for a month or two after docking this supply warehouse, enough for the earth to send a spacecraft to rescue.

Now the unmanned cargo spacecraft is flying towards Mars, although Mars is now a little far away from the earth, and when the spacecraft arrives, it will be farther away from each other, but the longer the distance can make the spacecraft accelerate for a longer time, so that the spacecraft can gain faster speed, so the time required to arrive is not much more.

Within a month or two at most, scientists on Mars could once again be fully secured.

In fact, as long as they follow the operation process, the two survival pods are enough for them to toss, there is really nothing on Mars that can hurt them, the Merrican people with bad character are gone, and the biggest damage of the legendary sandstorm is to make the base run out of power, and the matter of blowing up stones and smashing the base only exists in science fiction works.

By the way, there is also a "one in 10,000" probability of being hit by a meteorite, that ...... There was really no choice but to run.

Relatively speaking, the Crimson Base is not only safe, but also very "luxurious", at least much more luxurious than the Mars landing originally envisioned by mankind.

On the other hand, the arrival of four aliens has made the already frugal Enterprise even worse.
