Han. As serious astronauts, this lunar landing is not only to test the performance of the Mars spacecraft, but also to undertake other scientific research tasks. It is not easy to go up once, and the necessary scientific research projects must be done. Although the moon is very close to the earth, it is not something that ordinary people can climb on.

If nothing else, the cost of this moon landing alone will cost almost two billion dollars. Because this moon landing is an additional mission, Tang Feng patted his head and decided, but the cost is not a lot.

Not to mention the training expenses and other expenses for astronauts, the chemical fuel consumed for the "Kunpeng" moon landing alone requires four or five additional launches of the "Starry Sky-3" heavy-series rockets; although the average launch cost of the "Starry" series of carrier rockets has now been reduced to more than $20 million per time, it will cost more than $100 million more just to refuel the "Kunpeng."

Coupled with the replenishment of the "Eagle Falcon" and the replenishment of various materials on the Mars spacecraft, roughly calculated, such a moon landing operation will consume two billion US dollars. And that's when the Martian spacecraft is already in place, and if it's the same as the first moon landing, it will cost tens of billions of dollars.

Therefore, this kind of aerospace operation is really a bottomless pit, and the fault is that Tang Feng has been tossing and turning hard in the past few years, and he has made a lot of money, otherwise he really can't support such a space program.

Han. They each have their own tasks, but Tang Feng, the big boss, does not have any tasks on his body.

However, Dr. Schmitz's refusal to assign a task to Tang Feng does not mean that Tang Feng himself does not have a task. Compared to Han. Just like the scientific research projects they are engaged in, Tang Feng's task is more important.

If you can really get in touch with the people of the Alexander family, then it may be a great opportunity for the entire human race. It's just that Tang Feng himself doesn't know if he can get in touch with it, and he doesn't know what kind of attitude the people of the Alexander family will have after contact.

Everything has to be tried.

In Alexandria. Comrade Borisov and the American Bob. With Arnold's help, Tang Feng unloaded the Mars rover in the "Kunpeng" that looked like an all-terrain vehicle.

This Mars rover, named "Exploration" by Tang Feng, is different from the "Spirit" and "Curiosity" rovers launched to Mars by the United States before, the latter two are unmanned small Mars rovers, once something goes wrong, it almost means the end of the rover's life.

However, the "Discovery" is different, this kind of rover can carry people, and can pull two people on the surface of Mars at a time at a maximum speed of 50 km/h. If nothing else, this speed alone is far from being comparable to "Courage" or "Curiosity".

Because of the "Kunpeng" with a larger payload, Dr. Schmitz is also full of confidence, coupled with the support of Tang Feng, so Dr. Schmitz's team will spend more than a year to develop this real Mars rover that can carry people on the surface of Mars.

The Discovery rover resembles an all-terrain rover, with a length of 3.1 meters, a width of 1.7 meters, and a height of 1.8 meters. It has four huge non-inflatable run-flat tires, and between these four tires is the cab of the Discovery.

When the driver and passengers enter the cab and lock the hatch, the life-support system will automatically inject gas mixed with oxygen into the cab, and within three minutes, the air pressure in the cab can reach more than 0.8. In other words, it only takes three minutes to enter the cockpit of the "Discovery" in an extravehicular spacesuit, and the astronauts can take off their helmets and move normally inside.

This life-sustaining system and air conditioning system can not only provide sufficient air pressure and oxygen to the cab, but also adjust the temperature in the cab to keep it at a constant temperature. It is precisely because of this advanced life support system and air conditioning system that the "Discovery" rover is even more comfortable than the car conditions on Earth.

The core energy source is eight radioisotope batteries made of plutonium oxide and molybdenum, that is, nuclear batteries, which can drive the "Explorer" to travel more than 5,000 kilometers under full load.

In addition to the eight nuclear batteries, there are also two folding solar wing panels on the back half of the roof of the "Discovery" airtight module. When extended, each of the two solar wings will be eight meters long and two meters wide. In fine weather, the use of these two solar wings to charge the on-board solar cells for more than five hours can allow the Explorer rover to travel more than 50 kilometers without interruption.

Of course, this solar cell is only used as an auxiliary energy source, and the main power comes from the eight nuclear cells.

Because it is equipped with too many batteries, the "Explorer" Mars rover still weighs more than two tons despite being made of aluminum-lithium alloy.

However, the payload of the "Discovery" is very large, it can not only pull two astronauts weighing less than 90 kilograms to move freely, but also can carry more than 300 kilograms of supplies with additional loads

Of course, these data are tested on Earth, and if you go to Mars, these values will increase dramatically, after all, the gravitational pull of Mars is much smaller than that of Earth.

And now, the "Discovery" rover, which was supposed to gallop on Mars, has contributed its first "place" on the moon. Women's Aviation".

Because of Han. Just because they each have their own tasks, and almost everyone knows that this Mars rover worth more than a billion dollars is actually a large toy that the big boss himself made for himself, so no one is interested in the Mars rover.

Therefore, when everyone else was busy, Tang Feng leisurely got into the cab of the "Exploration", and after the pressure in the cab returned to balance, Tang Feng still had the leisure to light a cigarette.

Because it is Tang's "exclusive mount", Tang Feng specially explained that Dr. Schmitz installed a set of smoke exhaust equipment in the cab of the "Discovery", in order to solve his own smoking problem. Of course, this particular smoke extraction device also cost Tang Feng millions of dollars.

Tang Feng is very addicted to smoking, and if he is not smoked for a long time, he would rather not go to Mars. But Mars is also related to the upgrade of the star core, so Tang Feng specially explained to Dr. Schmitz that in the "Discovery" and the wheel cabin and core cockpit of the Mars spacecraft, a small separate area was specially opened up for smoking when he was addicted to smoking.

Just to solve Tang's smoking addiction problem, Tang Feng spent no more than 100 million dollars!

To put it bluntly, this is a real loser (to be continued.) )
