The first year of the Milky Way, December 19, Blue Star Time.

At eight o'clock in the morning, Fang Tianbo and Masashi Kishimoto, who were woken up by the alarm clock, started their day's work.

This time, in addition to the 510 tons of mass that was used to transport the satellite, they had 1,490 tons of carrying capacity, of which 1,030 tons were parts of 21 standard compartments.

The remaining 460 tons of mass are 50 tons of living materials, a 48-ton Mars landing spacecraft, a 26-ton Martian ground standard cabin, a batch of 41-ton probes, and the remaining 295 tons are all kinds of equipment and maintenance parts.

The second task of the first team of the Space Expeditionary Force is to build a Mars synchronous orbit space station, which is a modular space station construction technology that is very mature.

Fang Tianbo and Masashi Kishimoto are proficient in operating space operation robots, splicing together the parts of standard cabins, and No. 9527 is also helping to build a space station.

They are very fast, they can build a standard module in an average hour, and by about 18:12 in the evening, the Mars synchronous orbit space station consisting of nine standard modules has begun to take shape.

At 19:24, Fang Tianbo held a short meeting.

Fang Tianbo looked around at everyone and said: "Now that the Mars synchronous orbit space station has been preliminarily completed, from tomorrow onwards, our work will be assigned again, Yuri and Commissioner Lin will continue to take turns to guard the cockpit of the Lunar Chase to develop and monitor the orbit around Mars and the Blue Star communication work." ”

"No problem." Yuri replied.

Lin Lei also nodded in agreement.

"Zhengshi, you and the 9528 robot continue to build the Mars synchronous orbit space station." Fang Tianbo continued to command.

"Hey!" Masashi Kishimoto nodded and replied.

"I'm going to start the specific exploration work on Phobos and Deimos from tomorrow."

Exploration of Mars is their third mission, and the exploration of Mars is not only about Mars itself, but also about its two natural satellites.

December 20th.

The exploration work of Phobos presided over by Fang Tianbo has officially kicked off, and two geological satellites have already surrounded the big potato of Phobos.

There are two types of "photographic" instruments (called sensors) on the geological satellite, one is a reflective tube television camera, similar to a television camera; The other is a multispectral scanner, which can record the electromagnetic waves reflected from the ground separately by wavelength.

The two geosatellites placed on Phobos will obtain information on electromagnetic waves in various bands radiated or reflected by ground objects, and then send this information to the Ritisonate spacecraft.

Since the reflection of each object in different spectral frequency bands is different, after the spacecraft receives the satellite signal, the supercomputer of the Day-by-Day spacecraft will process and interpret this information according to the spectral characteristics of various substances it has mastered, so as to obtain detailed information such as the characteristics, distribution and state of various resources.

Phobos is an irregular moon, very small, the size of Phobos is only about 26.6 kilometers×22.2 kilometers× 18.6 kilometers in size, the shape is a bit like a potato, the average distance from the center point of Mars is 9378 kilometers, about 6000 kilometers from the Martian surface.

In addition, there is a huge meteorite impact crater on Phobos, like a large potato being bitten, this meteorite impact crater is called the Stickney impact crater.

Fang Tianbo looked at the data fed back by the spectrometer of the geological satellite, and he said to himself:

"The Phobos feedback spectrum contains moderate absorption at ultraviolet wavelengths below 0.4-0.5 microns, while at longer wavelengths there is no noticeable feature but slight reddening. In the vicinity of the wavelength of 3 microns, there is a feature called water absorption, which indicates the presence of water on Phobos. It is a distinctly C-type asteroid. ”

The spectrum of the so-called type C asteroids is very similar to that of carbonaceous chondrites (CI and CM types), except that they do not contain hydrogen, helium and volatiles, and their chemical composition is almost the same as that of the Sun and the original solar nebula, and there are also hydrated (aqueous) minerals.

Fang Tianbo observed the spectral feedback of the Stickney impact crater, and said to himself in some surprise: "Huh! There is a metallic reaction in the center of the impact crater, and it appears that the meteorite that hit Phobos is an S-type (iron-iron) asteroid or an M-type (iron-nickel) asteroid, although the details need to be explored by landing. ”

After completing the remote sensing of the geosatellite, he sent a small sampling spacecraft to Phobos, which used an ion engine to easily land on the surface of Phobos, where its gravitational pull was negligible because Phobos was so small.

The sampling spacecraft selected six locations on Phobos, using 10 copies for each location, and the drilled samples were quickly sent to a laboratory chamber on the Mars geosynchronous orbit space station, which was isolated from the space station.

The isolation of the sampling and laboratory chamber from the space station or spacecraft is also a dead rule of safety regulations, after all, no one knows that these asteroids do not contain deadly viruses or bacteria that are difficult for humans to immune, so all materials collected from alien planets must be isolated.

The direct close contact of human workers or scientists in science fiction movies with alien matter of unknown origin is strictly forbidden in the Human Innovation Alliance, after all, this kind of behavior may bring unpredictable risks.

Soon the laboratory chamber began to perform a comprehensive and detailed assay analysis of the samples.

"All the samples generally contained crystal water, and the content was quite high, the highest was 31.6%, the lowest was 4.3%, and the average water content was about 18.71%."

"In the central area of the Stickney impact crater, the silica content is 14%~16%, the calcium carbonate is 34%~35%, and there is about 3% crystal water, 27%~28% iron oxide, about 3% nickel, and the remaining 10% is other inorganic salt impurities. It appears that the asteroid that hit Phobos to form the Stickney crater is an S-shaped stone-iron asteroid. ”

"No biological reactions were detected, which is good news." Fang Tianbo said to himself while looking through the test report.

In the next week, Fang Haibo successively completed the preliminary exploration work of Phobos and Deimos, and launched a landing spacecraft to the equatorial region of Mars to establish a Mars forward base.

Masashi Kishimoto and 9527 have also completed the construction of the Mars geostationary orbit space station.

The first year of the Milky Way, December 28, Blue Star Time.

"Yuri sent a message to the Blue Star side that the Riturgy spacecraft will depart for Blue Star at 10:20 this morning." Fang Haibo commanded.

"Roger." Yuri hurriedly operated the communication system to send a message to Blue Star, and it took about 17 minutes for Blue Star to reply and communicate.

"Captain, the new Chang'an space station has agreed to our return to Blue Star."

"Okay, let's get into the anti-load cabin."

The four of them entered the life support capsule, and as soon as the time was up, the spacecraft left the Mars synchronous orbit space station and headed for a distant starry sky.

At this time, the distance between Mars and Blue Star has become a little larger, reaching about 143 million kilometers, more than 10 million kilometers farther than before.

However, for a sub-light spacecraft, it was just over two hundred seconds more, and after the acceleration phase of the Sun-Chasing with the condensed matter shield, it increased its speed to a cruising speed of 13.8% of the speed of light.

At around 4816 seconds, the spacecraft entered a deceleration phase, which also marked that it was about to enter the Blue Star region.
