I ask you to build tractors, but you build rockets?

"Five thousand one hundred and forty...the error is 2.5%."

Deng Lei looked at the numbers on the laser rangefinder and picked up the GPS to confirm.

The 'Robin Hood' test explosion was located in the central area of ​​the mine. It used a semi-buried detonation, and its scope of action was mainly on the lunar surface.

The purpose of this is to test the great idea of ​​nuclear bombs to improve the landscape. Although this explosion cannot form a great plain, as long as the observation results are similar, it means that it is feasible to use nuclear bombs for infrastructure construction.

There are seven unknown experimental devices near the "Robin Hood" explosive device, four domestic, two Ami, and one Lucia.

All experts chose to ignore them when mentioning them, and just placed them according to the instructions and placed observation instruments everywhere outside the core area.

There are also two micro-satellites in the sky with specially enhanced protection, specially used to take pictures of explosions from space.

The ignition time is set at 20:15 pm on May 9, Beijing time. At that time, the Wutu Space Station and some important spacecraft are operating on the other side of the explosion surface, which can avoid most of the impact.

As for the impact on the earth's orbit, there is no need to worry. Since the tidally locked moon always faces the earth, the mine is located on the back side of the moon, and the impact is basically less than 380,000 kilometers away.

Next to Deng Lei was astronaut Tim, who was holding a handful of long objects tightly.

What he holds in his hand is the safe state release key, which needs to be inserted into the special groove of "Robin Hood" 8 hours before the explosion to unlock it. He is the only one who keeps it during the whole process. As for the detonation order, the Royal Air Force issued a delay one hour in advance. When the detonation command is given, it will ignite and trigger automatically when the time is up.

It was still nine o'clock, more than two hours before Tim went to plug in the key. He had stayed away from the group and was ready to receive orders from London at any time.

The atmosphere on both the moon and the earth is actually a bit tense and full of maturity. The cause is naturally Ami's sudden attack. Although it was suppressed, no one can guarantee that something will happen at the last moment.

Only at 19 o'clock, when the delayed detonation order was issued, everything was settled. To prevent the explosion, John would have to come to the moon to dismantle the nuclear bomb with his bare hands.

While waiting for Tim to release the key, all the seven astronauts who landed on the third batch could do was to take the trouble to check and chat about all kinds of things, but wisely avoided what had just happened on the earth. .

"Hey, Artemis 5 was supposed to assist us, but why did I hear it was delayed until the end of May?"

Claire's ambitious "Centaur" plan has long been announced to the public. After the launch of Artemis 4, the outside world expected Aramco to return to its peak and conduct a moon landing in two months. According to the schedule, Artemis 5 will naturally It should launch at the end of April.

However, on April 22, NACA suddenly announced that the Artemis V mission would be postponed to late May due to interference from the United Mining hydrogen bomb test explosion.

The outside world is still convinced, but everyone inside United Mining knows that Aramco originally planned to use Artemis 5 to send the test device over and perform a landing mission near the mine. The Aviation Development Committee also maintained its acquiescence in previous exchanges.

But who knew they suddenly gave up again, and it took a month.

Tomarsov, who couldn't sit still, asked the others curiously, and immediately received the answer from Nikolai Talal, the Russian astronaut and engineer:

"Ha, of course it's because ESA is out of food."

Talal is also a mid-level official within ESA and obviously knows a lot:

"The Orion spacecraft used in the Artemis project was jointly manufactured by NACA and ESA. Lockheed Martin was responsible for the command module. However, we originally only planned to produce six service modules. It took great efforts to produce the ones used in Artemis 4. .

They have not been able to find a way to replace the service module produced by ESA. This delay is also due to ESA's manpower shortage. We are making every effort to manufacture the Hermes space shuttle, which has the highest priority.

I also heard that Tim was originally selected as Artemis Four, but he let that unlucky guy Cole take over haha..."

"Talal, I passed the selection and entered the Canopy Mission very early. United Mining started buying insurance for me half a year ago!"

The two people from the Yu country and the Yi country started arguing on the radio without any pain. At first, they communicated in half-baked Chinese, but in the end they both spoke their own language at a speed that was completely inaudible.

Deng Lei ignored these two living treasures and connected to the channel of the Yushu base alone.

"I'm Li Wei."

"Are you and Xiaofu ready? Geological experts say it may cause an earthquake."

"Don't worry, the straight line is 200 kilometers long. We will all wear spacesuits. It's just that we won't be able to communicate so clearly for a while."

After the explosion of 'Robin Hood', it is foreseeable that the GPS and all-lunar call services composed of cube satellites and micro-satellites will definitely be hit hard. The fragile small satellites with an orbital altitude of a minimum of more than ten kilometers will be the first source of soft X-ray radiation and electromagnetic pulses. A round of sacrifice.

This set of GPS has been very popular among astronauts. Without it, it is like driving without looking at the map. They are always afraid of messing up something.

Deng Lei: "Soon we will also be able to pick up green glass on the moon. I remember that we have a special protective box in our supplies. I should be able to bring it."

Li Wei: "Then you have to file a report to apply for a disposable spacesuit first. By the way, don't forget to send the coordinates of the lunar rover when you leave. I'll have the explorer drive back."

The six new explorer robots carried by Dawn 2 were also aboard the Jiuzhang, and were unloaded together with the two new lunar rovers. They first helped complete the nuclear explosion preparation task, and then needed to be carried out by themselves when the Jiuzhang was evacuated. Rush back to the Yushu base and hide.

"I understand... don't tell me, it's really interesting for the spider robot to ride a motorcycle... It's over, please report any situation at any time."

"Wish you good luck, Captain Deng."

The follow-up of NX17 has nothing to do with David. Internally (within the earth), it is more appropriate to let a more professional intelligence agency do it.

Now David was sitting in front of a row of screens, and the fluctuating radio patterns were constantly changing.

This is a signal from several Mars probes, which are working hard to find signals that appeared in the M event.

As long as a signal is detected within at least 3 days and at most 7 days, it can basically prove that David's "energy threat theory" is established. Every time humans use nuclear bombs, they are lighting a match in the dark.

If the fastest speed is used, the current delay from the moon to Mars is 187 seconds. Assuming that the alien detection source is on Mars and immediately forwards the signal, it will take more than 6 minutes to be discovered by the Mars probe and transmitted back to the earth. The earliest The satellite warning can be received at 8:23 AM Central Time on the 9th.

David looked at the time. It was only 00:10 now. Tim should be plugging in the key and then quickly escaping back to the Nine Chapter spaceship and heading to the space station.
