Chapter 880: Limitations of the Launch Window
However, it is only the beginning of June, and the formation of extreme weather in the sea near the Great Tamu volcano is generally in August or even September, because only during this time period is the hottest time of the year in the northwest Pacific Ocean, and it is also the time when extreme weather such as typhoons are most likely to form.
There are still more than two months to go, and Tang Feng can afford to wait, but in order to paralyze those observers, Tang Feng simply controls the Great Tamu Volcano and stops the eruption now.
Aren't you observing? Let's float at sea for two months
The matter of the Great Tamu Volcano can be put aside for the time being, but the matter of outer space cannot be taken lightly by Tang Feng.
Since its successful landing on the moon last May, Star Exploration has made a name for itself on the planet, although there are still people in the United States such as Elon Anderson. Elon Musk's SpaceX, Larry. Paige, Eric. Schmidt, James. Cameron co-invested in private companies such as Planetary Resources, but in the face of strong star exploration, these originally famous private space companies are overshadowed.
Elon. Although Musk's SpaceX has a strong technical advantage in rocket recovery, SpaceX was the most powerful private space company in the world before the emergence of Star Explorer, and even obtained a series of rocket launch contracts with NASA.
However, with the successful recyclability of the Starry Sky series of heavy-lift launch vehicles, SpaceX's advantage in this regard has been lost.
Compared with the Starry Sky heavy launch vehicle, Mascu's Falcon family of launch vehicles is simply weak
Since the successful implementation of the moon landing operation, Dr. Schmitz and his team have used the "Star" heavy-lift carrier rocket to transport more than 200 tons of materials and equipment to the geosynchronous transfer orbit in this year. The Starry Sky 1 rocket, which had been on a mission to launch the lunar operation, lifted off again 10 times, sending seven sets of equipment modules and necessary supplies and personnel to the lunar spacecraft.
Now in geosynchronous transfer orbit, the lunar spacecraft that landed on the moon last year has changed dramatically, and with the addition of seven other functional chambers, the current lunar spacecraft has become a medium-sized space station.
At the time of the lunar landing last year, the lunar spacecraft already had three functional compartments. From beginning to end, there are ion engine functional compartments, small nuclear power plant functional compartments and the core lunar spacecraft functional compartment, if you count the "Eagle Falcon" landing compartment, the entire lunar spacecraft used in the lunar landing operation has a total of four functional compartments.
The main body of the Mars spacecraft designed by Dr. Schmitz is composed of the lunar spacecraft's functional compartment as the core, with 13 additional functional compartments and 12 wheel compartments with a radius of 75 meters.
The assembly of the wheel cabin was put last by Dr. Schmitz, and now the main body of the Mars spacecraft is assembled. Therefore, in the past year or so, the "Star-1" heavy-lift carrier rocket has lifted off again 10 times, and delivered another seven functional warehouses and related equipment and materials to the Mars spacecraft.
It is worth mentioning, in addition to NASA. Both the Huaxia and Russian space agencies have joined in the formation of the spacecraft, but they are transporting crews to the spacecraft. After all, assembling a Martian spacecraft and assembling a lunar spacecraft are completely different in terms of difficulty and workload. The lunar spacecraft can be directly docked through computer control, but the Martian spacecraft has a lot of work that needs to be carried out extravehicular operations.
Therefore, astronauts who carry out extravehicular operations are indispensable.
Like Han. Zheng, Du Yun and another astronaut entered space again after New Year's Day and stayed on the Mars spacecraft for about three months before returning to the ground.
Russian cosmonaut Alexander Murray, who once carried out the moon landing operation with Tang Feng. Borisov, together with another Russian cosmonaut, also worked with Han Anderson. Zheng, Du Yun and an astronaut under Tang Feng. The six of them stayed together on the Martian spacecraft for more than three months.
As for the other two American astronauts who followed Tang Feng on the moon landing operation, George . Anthony and Robin. Coroso, after returning from the moon. After only resting for more than two months, with the cooperation of another American astronaut and three astronauts from Star Exploration Company, they also entered the Mars spacecraft and stayed on it for more than four months.
Thanks to the support of these astronauts, the Mars spacecraft was built faster than Dr. Schmitz's plans.
At present, the main body of the Martian spacecraft has ten functional compartments and a "Falcon" landing spacecraft. From beginning to end, there is the auxiliary ion engine functional cabin, the auxiliary small nuclear power plant functional cabin, the cockpit, which is the core of the lunar spacecraft, the communication module, the spare fuel tank, the electronic equipment cabin, the main living materials reserve cabin, the water and oxygen manufacturing cabin, the second main fuel tank, and the auxiliary living materials reserve cabin, with a total length of more than 100 meters.
At present, the main body of the entire Mars spacecraft is still missing a main nuclear reaction fuel tank, a rotating functional compartment behind the main fuel compartment and a rotating body connected to the main spacecraft, a functional compartment for the main small nuclear power plant, and a functional compartment for the main ion engine.
Once all four functional chambers are in place, the main body of the entire Martian spacecraft will be built, followed by the most complex construction of the rim cabin.
The construction of the main body of the Martian spacecraft alone will take at least a year and a half. As for the construction of the twelve wheel cabins, it will take two years. So for now, the entire Martian spacecraft is only about a third of the way through.
However, Tang Feng is not in a hurry now, one is that the star core still needs time to upgrade, even if the Mars spacecraft is built now, Tang Feng will not carry out a manned Mars exploration plan now. After all, Tang Feng invested heavily in this plan, but the factor of the star core occupies an extremely important aspect, and if the star core is not well prepared, Tang Feng will definitely not set off.
Of course, there is another unavoidable factor is the limitation of the launch window, for the launch vehicle itself, there is no too strict launch window limit, and it can be launched at any time, but when the launch vehicle is used to launch a spacecraft, it cannot be launched at any time.
As we all know, the orbital period of the Earth is 365 days, the orbital period of Mars is 687 days, and the period of the conjunction is 779.9 days. Due to the non-uniformity of the planet's rotation, it can be said that the interval between the encounters at the closest point is about 780 days, that is, at the time point of 2 years and a month, which is also called the launch window of Mars, and if we miss the window, our rocket will be empty. Because we are far away from Mars, there is a time difference, we can launch the rocket in advance, the speed can be controlled to the appropriate one, if it is postponed, we will accelerate to catch up, so this time has a certain span.
Thus, the Mars launch window is as long as 780 days. The closest launch window is in the middle of next year. Next year's launch window is obviously too late, and the Mars spacecraft has not yet been built at that time, so we will have to wait for the next launch window, which is from now on, and it will take about three years to do so (to be continued). )
