The spider lander uses eight mechanical feet to flexibly pass through the rugged roads along the way, and comes to the unexpectedly hot fountain without any danger.

As this thermal fountain continues to erupt, the surrounding ice layer is more unstable.

However, there are pros and cons, because during the eruption of the thermal fountain, a large amount of groundwater is brought to the ground, and these groundwater are condensed into ice by low temperatures near the nozzle of the thermal fountain.

Therefore, near the nozzle, an ice chimney like a crater is formed.

The ice chimney of this small thermal fountain has grown by about 71 meters upwards from the bottom of the valley and is still growing.

The ice chimney is similar to a crater, surrounded by a gentle slope. The mechanical foot of the spider lander is adjusted to a crawl mode. The mechanical foot uses sharp alloy spikes to bury on the ice surface of the gentle slope and crawl upwards.

However, the continuous eruption caused great snowfall around, and even mixed with hail.

As the spider lander advances, the body is constantly colliding with hail, and is moving forward with difficulty.

Although it is a small thermal fountain, the groundwater and water vapor emitted by this thermal fountain can actually rush up to 140 kilometers of outer space.

This is mainly because Europa's gravity is relatively weak, and its atmosphere is not that thick, and the pressure of the thermal fountain is very large, so it can erupt to an altitude of 140 kilometers.

Finally arrived at the chimney entrance, and at this time the spider lander was firmly fixed to the ice with mechanical feet, and could feel the continuous hot fountain.

The spider lander extended its sampling robot arm and collected more than a dozen samples of water vapor and groundwater, which were emitted by a thermal fountain.

The samples were sent into the testing equipment and preliminary analysis began.

Su Xiaoyu, who was at the Mars outpost, looked carefully at the pages of data fed back with an expectant look.

"Huh?" Su Xiaoyu saw a very valuable data and found an amino acid molecule in sample No. 7.

This discovery made him overjoyed. Although only one of the 12 samples contained amino acids, it means that there is a very likely existence of living organisms in Europa's underground ocean.

Continue to issue instructions to the Heather, let the spider lander continue to collect eruption samples from the hot fountain, hoping to find more organic evidence from it.

Sure enough, in the samples collected one after another, a lot of organic components were analyzed, and even a cell similar to cyanobacteria was found in sample No. 9527.

Various analyses show that Europa's underground ocean not only has abundant water resources and geothermal energy, but also strange organisms have been born.

In fact, the relevant research teams have speculated about the possibility that Europa may have life.

Because in Jupiter's orbit and in the adjacent asteroid belt, the probe found traces of amino acids and microorganisms in some ice-containing asteroids.

At first, researchers suspected that it was a microorganism from Mars, but as the research deepened and various samples were collected, the gene map was compared.

The researchers got an unexpected result, that is, the genetic sequences of some samples have little to do with Martian microorganisms.

Even if it is related to Martian creatures, the relationship between the two is that Martian creatures will appear later, which means that the creatures on Martian are most likely not "indigenous people" but alien immigrants.

So where did these alien immigrants come from?

After a series of investigations and analysis, the researchers discovered a phenomenon, that is, the closer the samples collected in the asteroid belt, the younger the genetic sequence of the samples are.

However, in the asteroid belt close to the orbit of Mars, the gene sequences found are relatively old.

According to distance, the younger the gene sequence, the closer the gene sequence is to the origin of the gene; on the contrary, the older the gene sequence, the further the location of the gene sequence is to the origin of the gene.

In other words, more outer areas such as Jupiter or Saturn are the birthplace of these creatures.

This is also the reason why the Ministry of Aerospace has worked so hard to send a detector to land on Europa, because it is very likely that this place will be the origin of life.

Now it seems that the researchers' speculation is correct. Among the gene samples collected by Europa, it is indeed highly consistent with the gene sequences found in the asteroid belt.

This discovery will help humans better understand the origin and evolution of life in the solar system.

It also proves that life may also be born in satellites of gaseous planets.

The next work of Heather Flower is to continue to collect more genetic samples and complete the life map of the solar system.

In addition to Europa, the Ministry of Aerospace has also launched a probe to another planet with a high probability of life, Titan (Titan), and is expected to arrive at Titan around July next year.

The traces of life have been discovered in various parts of the solar system, which has forced the Federal Sciences Institute of Cosmic Life Research Institute to further correct the reference indicators of the life planet.

At the same time, this has caused a lot of new debates within the academic community.

For example, the origin of life of Blue Star.

Is it that the Blue Star itself gave birth to life, or is the seeds of life of alien creatures taking root and sprouting on the Blue Star, or that the Blue Star itself gave birth to life, but alien creatures also entered the Blue Star, and the two hybridized.

Now more and more evidence shows that the last point is that Blue Star itself gave birth to local life, but later it was influenced by aliens one after another.

Especially the archaebacteria of Europa, which were mixed in asteroids during these billions of times, visited Earth-like planets such as Mars, Blue Stars and Venus.

During this period.

They reproduced and thrived on ancient Mars and once developed various microorganisms, single-celled organisms and small multicellular organisms.

We also work with the protists on the ancient blue star to transform the ecological environment of blue star. With the running-in of time, the two gradually merge together to form today's blue star ecosystem.

On Venus, they also use the rich light and heat conditions here to develop brilliant life. Unfortunately, at a certain moment, Venus underwent a drastic change, causing the planet's rotation to slow down, the magnetic field of the earth's core to fade, and finally become today's hell planet.

The reason why researchers know that Venus has life is that after the establishment of the floating city, some ancient biological fossils were discovered in a series of developments in the Venus Zone.

According to carbon 14 detection, these ancient biological fossils were all life 763 million years ago.

These evidences prove that 763 million years ago, Venus was still a planet with a climate suitable for life, and the destruction of all this may be a major change around 763 million years ago.

Since the three Earth-like planets in the inner layer of the solar system all have life (including those that once existed), Jupiter, Saturn, Uranus and Neptune in the outer layer of the solar system may also have life.

The results of Europa's investigation further prove this.

Judging from the situation in the solar system, the probability of other stellar systems having life planets will be raised to a very high level.

Even if the probability of intelligent life being born is relatively small, once the base of the life planet is larger, there will always be one or two lucky people.
