"Radiation and thermal plumes are being analysed, and the thermal energy is changing, but very regularly."

"The results are in, and the radiation values and plume data are normal."

"Landing craft No. 1 just passed over a plume, and the data collector seems to have collected something, and the archangel has already begun to calculate."

"The systems are normal, the condition is good, and the destination is stable."

Although Elsa is not on the landing craft, her gentle voice keeps ringing on the landing craft, and as a good psychiatrist, she has a hundred ways to calm people in a tense state.

"Haha, Elsa, your voice is much better than that of the archangel."

"Elsa, that's it, you broadcast real-time data for us."

Although the archangels can also do this, for these astronauts who have been flying in space for more than a year, it is the human voice that calms and settles them down, especially now that they land on a strange planet.

Europa, the second closest moon to Jupiter, is Europa, it has a large ice crust, under which is a liquid ocean, and because of its proximity to Jupiter, Jupiter's gravitational pull has a large effect on it, making geological activity very active, resulting in a smooth surface of Europa, rarely with an altitude drop of more than a few hundred meters.

"The landing gear is ready, ready to land."

"Ladies and gentlemen, sit down and get ready to land."

"Lock your destination and count down to 30 seconds ......"

Everything was normal, but the landing module suddenly shook, which made the astronauts inside a little panicked.

"Oh my God!"

"Don't get an accident!"

"What's going on?" Gordon asked hurriedly.

Almost at the same time, Sidney, who was looking at the data, and Elsa, who was broadcasting, and the "archangel" all spoke.

"It looks like a hot gas vent suddenly erupted!"

"It's a hot gas vent!"

"The hot gas vent erupted suddenly, and we were right above it."

"Archangel takes full control, stabilizes the ship, and takes us out of here," Gordon said loudly, "Continue to land towards your destination, don't panic!" ”

"Understood!"

"Flying away from the hot gas vent, the course is slightly offset......"

"Ten meters, five meters from the ground, landing!"

The violently vibrating spacecraft boomed, and the spacecraft stabilized at once, and there was no more shaking.

"Success?" Beth asked, confused.

"Yes, it worked, wow! Bang Bang Bang! Sidney cheered and applauded.

"Archangel, report our bearings." Gordon asked.

"Current azimuth offset, 74 meters north of the intended destination, ice thickness ......"

As the archangel reported, more detailed data appeared on the screen in front of them, and they were relieved after reading it.

Although the hot gas vent was encountered just now, the landing craft was a little unstable and deviated from its position a little, but fortunately, it was not much, it was still in the safe zone, and it had little impact on the mission.

After confirming that there was no danger at the landing site, the four of them began to act separately, analyzing the data of the data, sorting out the items, reporting the task of reporting, and overhauling the landing craft.

The landing craft was sprayed just now, and the vibration when landing was so big, and the surface was not very flat, so it was inevitable that there would be problems, which was not only related to their sacred mission, but also related to their safety, and Mario's responsibility was great.

After checking everything, Mario looked at the list and said: "There is nothing wrong with the main body of the landing craft, only the ice impact scratches where it suffered a frontal impact, a landing bracket is a bit of a problem, and everything else is a minor problem, mainly the parts that hold the drill bit are impacted, but the problem is not big, you can replace the parts." ”

"That's good, if you can handle it, you don't need to use the No. 2 landing craft." Gordon said.

"In this way, Mario, you give priority to repairing the hollowing device, and you arrange the repair order of other things yourself, and we will complete the task as soon as possible and get out of here as soon as possible."

"No problem."

They have spare landing craft as part of the mission and safety, but this one is not a big problem, so there is no need to call that one down.

Space on the landing craft is limited, so the parts that are not very necessary are not prepared, but are stored in the form of materials that need to be printed out with a 3D printer.

Replacing the parts of the drilling device needs to be removed from the cabin, although the environment here is also harsh, whether it is the strong radiation from Jupiter or the extreme change in temperature, one-seventh of the home planet gravity can walk lightly, but as a professional engineer, Mario quickly completed the repair work of the drilling equipment.

Due to the limited equipment, it is a bit difficult to fix 100%, but there is no delay in drilling.

After the repair was completed, there was no delay, they immediately started the drilling work, although the calculation data said that it was safe here, but Europa has always been retracting and deforming under the gravitational pull of Jupiter, this change makes the possibility of a large crack here is not zero, and the task is completed early.

"The drill bit is ready, the arm extends normally......"

"Thermal ready to start ......"

"Let's go."

With the thermal drill bit disappearing from the ice, their quest for life in Europa finally begins.

The drilling time was very long, and it was expected to take nine hours to break through the ice, and they couldn't rest for nine hours, or they didn't dare to rest if they wanted to, because the ice was shaking all the time.

As a result, Mario clung to the handrail of the landing craft every time he left the capsule, and stopped work immediately as soon as it shook.

As previously calculated, Europa's ice does move very frequently, and their area is only relatively safe, and as they drill deeper, the more data they get, and the reality is much more complicated than they thought.

Fortunately, the situation is still relatively stable, and the ice has finally been pierced.

At this moment, even Mario suspended the maintenance work, and everyone gathered excitedly in front of the main screen, watching the picture transmitted back by the diving equipment.

The Sun is so far away that it is only a small spot of light in Europa's "sky", and the largest and brightest is Jupiter, but it is wrapped in a thick layer of ice, and the light does not reach the subglacial ocean at all.

Through the lights that come with the diving equipment, they found that the place where the ice connects to the sea water is very similar to the underwater scene of the ice in Antarctica, and they can even hear the sound.

"Whew-"

Everyone looked at each other, and Beth, a marine biologist, frowned and said, "Sounds like ...... The call of a sperm whale. ”

"Where did Europa get the sperm whales?" Mario looked confused. "And it's all under the ice."

"Maybe it's a cave." Gordon said calmly, and then asked Sidney, "How's it going, has the data changed?" ”

"The underwater radiation is very low," Sidney said as he looked at the data, "close to the level of the home planet ocean, and a heat source has been found, very close, it should be the one calculated earlier, so the situation here is better than we thought." ”

Just as they were studying the things, the archangel's voice suddenly rang out, and the monitor reacted quickly, and the bright green box framed an object.

"Discover the light source, discover the life reaction!"

"Huh?"

After only a moment of stunned effort, the originally unknown light source quickly approached, and when it got closer, everyone found that it was actually an octopus.

Or a glowing octopus!
