Approach “black hole”

According to pre-defined program, under the guidance of automatic guiding system supported by supercomputer, the space exploring ship leaves the solar system and flies towards deep space.

"It is very busy in universe. As soon as we left earth, those UFOs have followed us." Says the ship commander while drinking tea inside the commanding office.

"That is true. Those aliens increase their activities in universe. This also proves that there are huge changes in universe. I guess that those huge changes in universe disturb their normal lives and drive them out to search for new survival places. " Says the science leader.

Day after day followed by UFOs, the space exploring ship flies towards the huge "black hole" which moves towards earth in high speed.

"This time, we are going to visit the huge "black hole". We must be very careful. We can only stay along the boundary of the "black hole" to collect information. We shall never be too close to the "black hole" so that we will not be pulled into the "black hole" eventually and never come back again." Says the instruction leader.

"I agree with you." Says the science leader.

Day after day, the space exploring ship flies towards the edge of huge "black hole" closer and closer while being followed by UFOs.

This morning inside the commanding office, people discuss present situation.

"Tell you a new situation. Although we are still far away from the huge "black hole", we are still affected by it." Says the pilot leader.

"It is true. Looking from far way, there are many asteroids moving towards the "black hole". This must be the effect from the huge "black hole"." Says the science leader.

"Look at those UFOs. They follow us all the time. They are our sincere friends." Says the communication leader.

There are more and more asteroids moving towards the huge "black hole" while the space exploring ship is closer and closer to the huge "black hole".

"Should we fly backward for a while to check if we are still capable of flying away from the huge "black hole"? Otherwise, if we cross a point, we will never be able to fly away from it." Says the monitoring leader.

"This is a reasonable doubt. We must define a program to check the flying away capability from the huge "black hole" for a period of time. In the case, we can be sure that we will not be pulled into the huge "black hole" eventually." Agrees the science leader.

"OK, I agree with you. Let the science leader and the pilot leader take preventive action to protect us from being pulled into the huge "black hole"." Says the ship commander.

In the following journey, the space exploring ship flies forward for a time and backward for a very short period of time to make sure that the space ship can fly away from the huge "black hole" to avoid being pulled into the huge "black hole".

"Hopefully, we will be safe in this way while flying towards the huge "black hole"." Says the environment leader.

"Tell you another new situation. About five day flying distance in front, there is an asteroid with the same size of our earth flies towards the huge "black hole"." Says the monitoring leader.

"This is a very interesting situation. What shall we do next?" The ship commander asks the science leader.

"We can catch it up from behind. We can even land on that asteroid to take a good look at it. Maybe, we can find something interesting there." Says the science leader.

"Any suggestions from anybody?" The ship commander asks everybody in the pilot controlling room.

When there is no more new suggestion, the ship commander gives the order to land on the asteroid in front. The instruction leader issues a series of instructions to related function teams to execute the order. Under the co-operations of the monitoring team, the communication team, the defense team and the pilot team, the space exploring ship approaches the asteroid with the same size of earth gradually. Of course, during this approaching process, the ship still flies backward to make sure that the ship still can fly away from the "black hole".
