Judging from the current position of Phobos, after Callimos passes through Mars, it will pass by Phobos, and the closest distance between the two sides is no more than 10,000 kilometers, if Phobos is detonated in advance, the fragments of Phobos may even hit Callimos head-on, making the impact most powerful.

Ling Yu immediately made a decision in his heart: "Order, the explosion of Deimos is canceled, and everyone is on standby; Phobos waiting for the blast order! ”

"Yes!" Wang Tianyu agreed and immediately conveyed the order.

The men arranged by the fleet near Deimos immediately died down, and no one dared to stab at this time, even if they were unwilling in their hearts.

But to tell the truth, deep in the hearts of those people on Deimos, they were actually quietly relieved.

In the case of Phobos, on the other hand, everyone instinctively tensed their nerves.

On the main screen of the Nanzhou bridge, Ganymede, which is larger than Mars, is approaching Mars step by step, and various data is rapidly leaking on the auxiliary screen on the side.

"Report, Europa's gravitational pull is interfering with Mars, and Mars is drifting out slightly!"

Ling Yu's nerves were severe: "Are you going to start?" ”

"Here we go." Xu Moliang was solemn.

Ling Yu asked in a low voice, "XCMG, Ganymede Zero is so fast, and its mass is greater than that of Mars, how far can it be reduced with Mars?" ”

"I don't know." Xu Moliang said, "Speed, orbital altitude and timing of departure all have an impact. ”

Ling Yu nodded and continued to stare at the screen.

He had always worried that Callisto would send a fleet to escort him when it approached Mars, but the aliens didn't do that at all, and there wasn't even an alien spaceship in the vicinity of Callisto.

At this time, the distance between Ganymede and Mars was already very close, and Wang Tianyu suddenly let out an exclamation: "Mars, the speed of Mars is increasing, and it is now 24.15 per second...... 24.18…… 24.22, and it's still rising! ”

"Monitor closely, how's Callisto Zero's speed?"

"It's descending, the rate of descent is small, it's now 82.22 kilometers per second!"

"How long will it take to get out of Mars?"

"Between 240 seconds and 270 seconds!"

"Continue to monitor and report any situation at any time!"

"Yes!"

Ling Yu's eyes were fixed on the screen, and his heart became more and more uneasy.

From the end of January last year to the decision to implement the Mars program, to today's arrival of Europa, mankind has been preparing for this collision for a whole year, and the success of the impact will determine the fate of the earth.

The countdown in the corner of the screen jumps steadily, and at this time Callisto happens to be running to the other side of Mars, and the fleet and Callisto are separated on either side of Mars, if the fleet retreats some distance, you will see that Callisto is exactly behind Mars, and Mars is surrounded by half a circle of ice white like an annular solar eclipse.

The other half of the circle is obscured by the shadow of Mars, and the other half is the night of Europa.

The rare sight was fleeting, with Europa approaching from the outer side of Mars' orbit, and the Mars was moving faster and the position was clearly drifting outward.

Europa gradually flew in front of Mars, its gravitational pull acted on Mars, and the speed of Mars became higher and higher, but the speed of Europa was much faster than Mars, and the current situation was like Ganymede dragging Mars forward, the speed of Mars was coming up, and the speed of Callisto was gradually decreasing.

Callisto orbital data is also constantly being adjusted, with the latest data showing that the closest distance between Europa and Deimos is about 8,000 kilometers.

But now was not the time to detonate Phobos, Ling Yu's two hands were clenched into fists, and cold sweat was faint on his forehead.

Not only Ling Yu, the Fourth Fleet has one count, which one of them is not nervous?

"Thirty kilometers, Mars is orbiting at a speed of more than thirty kilometers!" Wang Tianyu yelled in a gaffe.

"Shut up!" Ling Yu snorted.

Wang Tianyu's sudden shout startled him, and he almost shouted the word detonation.

Now Europa is still in front of Mars, a few tens of seconds away from the sweet tipping point.

Half a minute later, Ganymede finally arrived at the best position, and Ling Yu immediately made a decision, and suddenly let out a loud roar: "Detonate!" ”

Although it is possible to get a better chance if he continues to wait, but at this time, Europa could fly away from Mars at any time, and Ling Yu could not wait any longer.

At the sound of an order, a hill on the top of Phobos suddenly collapsed and cracked, and dazzling light and countless dust burst out from the bottom of the mountain, and the hill was driven by the force of the explosion to separate from Phobos, and the super engine placed on the mountainside suddenly penetrated into the mountain.

The mountain and the super engine are closely connected together, and after two turns, the super engine starts, quickly stabilizes the attitude of the mountain, and then opens up at full power, pushing the hill weighing more than 100,000 tons towards Europa.

Behind the hill that flew away, several super engines ignited together, holding Phobos at an angle, and the other hill was aimed in the direction of Europa.

Another blast, and a second hill ran towards Europa.

Just like that, Phobos quickly fired four ammo, and the first hill was already flying close to Europa, and it was right in front of Callisto!

Europa was flying in an arc, but the hill's trajectory was a straight line, and the super engine behind the hill did its best to push the hill in an arc, getting closer and closer to Callisto.

The hill marked as Number 1 on the screen gets closer and closer to Europa, and everyone's hearts are lifted, and finally One crashes into the outside of Europa, plowing a trench hundreds of kilometers long on the surface of Callisto, and the ice and snow scatter along the way, although it causes a lot of damage to Callisto, but it is completely incomparable to the power of a frontal collision.

Everyone sighed in unison, and their voices were incredibly neat.

Before the impact, the driver of the super engine broke away through the escape system in time, and saw that the No. 1 mountain only hit the side of Europa, and the driver regretted it.

But it's too late to regret it at this time.

At this time, the second hill was already approaching, but it was even more biased, and it didn't even rub it, and it passed directly outside the atmosphere of Europa, and it didn't even startle half of the gas flower.

There was another neat lament on the bridge.

The first two mountains were floating from the outside of Europa, Ling Yu understood that this was his own urgency, if it was a little later, one of the two hills in a row would definitely be smashed in front of Ganymede, at this moment, he could only put his hope on the next few "ammunition".

Everyone's eyes fell on the third hill, which was in a very positive position from the star map, and as long as it continued to fly in its current orbit, it would be able to hit Ganymede head-on with unmistakable accuracy, completing the stated goal of the Mars program.
