Du Xiaosheng shook his head and said calmly: "This is not a joke, and it is not a crazy act of giving up his life in order to obtain the name of the first person to walk on Mars. ”

"Rationally, my spacesuit can provide me with oxygen for six hours of work, and the parachute bag for the Mars rover, as well as the propulsion device, are enough for me to land safely on the surface of Mars."

"For this Mars landing, hundreds of thousands of us spent 16 years of preparation time and invested more than tens of billions of dollars. Now just because we suspect that these devices have been damaged, we will abort this mission, and no one will be reconciled. ”

While speaking, Du Xiaosheng patted the space shuttle seat under his buttocks and said: "Our spacecraft can resist the gravitational pull of Mars, and after completing the inspection work, if the landing fails, in the worst case, I can use the propulsion device to rise to an altitude of about 3,000 meters, and when the time comes, you can take over, and the entire mission may not fail." ”

Du Xiaosheng's analysis is indeed no problem, he has extremely rich experience in skydiving, and skydiving at a height of 40,000 meters is not an unchallengeable thing, but the risk of the entire task is borne by Du Xiaosheng.

Whether it is the parachuting link or the rescue link, there must not be a slight mistake, otherwise, whether it is a lack of oxygen or a disaster in any detail, Du Xiaosheng will die on Mars.

"It's too dangerous, I don't agree with it!" As a risk assessment expert, Christina shook her head again and again, in her opinion, this is simply impossible, and Du Xiaosheng is likely to die in vain by doing so.

Paul groaned for a moment and said to Du Xiaosheng: "If you take down the Mars rover and bring you another set of spacesuits and two oxygen cylinders, then your time for working on the ground will be extended to 24 hours." If something happens, the chances of survival are much greater. ”

Christina didn't expect that Paul, who has always been steady, actually supported Du Xiaosheng's move, and her face immediately turned to Zhao Yunhan, trying to get support from Du Xiaosheng's wife.

However, Zhao Yunhan didn't deny it, she just looked at Du Xiaosheng and asked softly, "How sure do you think you are to do this?" ”

Christina couldn't understand the current situation, and she directly rebuked: "Incredible, are you all crazy? This will not work! ”

Du Xiaosheng smiled slightly, he looked at Paul and Zhao Yunhan, and said with a smile: "Although I haven't done that, I'm sure." ”

This is not groundless, the spacesuit provides Du Xiaosheng with the necessary protection, temperature, and oxygen, and the parachute bag carrying the explorer mechanical vehicle also has a super fast parachute opening speed, which is enough to cope with the pressure of one percent of the Martian atmosphere below the surface of the earth.

"This is just theoretical, Du Xiaosheng, no one has ever done a parachute jump on the surface of Mars, and none of us have even landed on Mars."

Du Xiaosheng had made up his mind at this time, ignoring Christina's concern, he said directly to Paul: "Go and prepare, bring me the parachute bag on the explorer, and I will go to the airlock cabin to change clothes now." ”

"Yes, Captain." When Paul heard this, he immediately turned around and went to prepare.

Christina cursed under her breath, "What the hell, you lunatic. Then he turned and walked quickly towards the preparation module.

Du Xiaosheng couldn't help but ask, "Why are you going?" ”

"Prepare the necessary kits, medical supplies, water and oxygen cylinders for you." Christina said without looking back.

Du Xiaosheng was stunned for a moment, then showed a smile and turned his head to look at Zhao Yunhan.

There were only the two of them left, and Zhao Yunhan floated over and hugged Du Xiaosheng.

Gently stroking Zhao Yunhan's back, she said softly: "This will be the most dangerous thing, you will use the jet behind the backpack to fly to the edge of the Martian atmosphere at 41,000 meters, I don't know how fast it will be to jump off on Mars, but I know that on Earth, this falling speed will reach 1281 kilometers per hour, which is faster than many fighter jets, and a small sonic boom will be formed around you!" ”

"And this is Mars, the atmospheric pressure is lower, and you will be many, many times faster! No one knows when to open the parachute, and you have to slow down with the help of jets to land safely. ”

Listening to Zhao Yunhan's nagging, Du Xiaosheng did not interrupt.

Of course, he knows that once he exceeds 1,200 kilometers per hour, his speed will be 3 times the speed of sound.

On Earth, in 2012, his friend Felix did it once at such a high altitude, and in 2014, the limit was raised to 41,000 meters.

And Du Xiaosheng will break this record on Mars.

This is almost impossible, and even with the power of a nation, less than half of the 44 exploration missions have a chance of success.

Du Xiaosheng gently patted Zhao Yunhan's back and said softly: "Don't worry, my spacesuit is specially made, and this time I will carry two parachutes, one of which is a spare parachute." ”

"I need to rely on you, using the satellite to report my altitude and speed. Remember to help me stream. Du Xiaosheng kissed Zhao Yunhan's forehead gently, and then said with a smile: "I promise you that I will go back with you." ”

Paul shouted at this time, "Du! I'm ready. ”

Du Xiaosheng kissed Zhao Yunhan's forehead, raised his head and responded, "I'll come to the airlock cabin to change clothes." ”

At this time, the ground command center heard that Du Xiaosheng was going to use the Martian parachute method to complete the exploration of the Martian surface carrier module alone, and they were all shocked and speechless.

It is said that the fighting national art master is bold, but compared with Du Xiaosheng, he is even more crazy!

Inside the airlock cabin.

Du Xiaosheng said with a smile while getting dressed at this time, through the live broadcast signal: "Hello viewers all over the world, I am Du Xiaosheng, and where I am now is the atmosphere on the periphery of Mars, we can see that the earth under our feet is the immigrant planet Mars in our dreams of all mankind." ”

"There's not very good news to report to everyone."

"The originally planned Mars landing plan is probably going to be canceled today."

"We had a little problem, we had a little problem with the fuel tanks, the drilling tanks, as well as the nuclear power tanks due to the landing failure."

"Now, I am volunteering for a personal landing on Mars, challenging an altitude of 45,000 meters to parachute to Mars, where the atmospheric pressure is less than 1 percent of the Earth."

"Note that this is not a free send-off plan, I will personally land and complete the judgment and repair work of three cabins. Once the repair is successful and the fuel tank is confirmed to be ready for use, we will restart the landing program. ”

AS HE SPOKE, DU XIAOSHENG WIPED THE SWEAT FROM HIS FOREHEAD IN THE AIRLOCK CABIN AND SAID TO GOPRO: "FELIX, I KNOW YOU'RE WATCHING MY LIVE BROADCAST, I CAN'T THINK OF IT!" I'm going to break your skydiving record on Mars. ”

"May I resist an impact far greater than four times the speed of sound, and pray for me!"
