NASA is launching DART (Double Asteroid Redirection Test) to space



The DART (Double Asteroid Redirection Test) vehicle's computer is equipped with multipurpose artificial intelligence that allows it to navigate to an asteroid. Then that probe shoots the asteroid by using kinetic energy arrows that can turn the asteroid out of its course. The thing in this kind of operation is to keep the asteroid in one piece. The DART is using the impact technique where the satellite is impacting the asteroid. Pushing it away from the trajectory. 

The idea is that DART itself will push the asteroid to another trajectory. But maybe the future versions of that kind of system are the darts. Small sub-probes that are impacting asteroid and then push it. When we are thinking about kinetic energy vehicles. Also, so-called dummy rockets can use for pushing asteroids away from their course. The rockets might equip with an impact cushion or gel head that makes the impact softer. At first, the manipulator's arm will throw the rocket into an asteroid. Then they would touch the surface of the asteroid. And that thing activates the rocket engines. 




There is there might be also the possibility to use soft-head rockets. Those are not penetrating the asteroids. If we think of the possibility that the system is used for asteroid mining. 

The penetration ammunition would be more useful if the purpose of the system is to cut the asteroid in pieces. The idea is that the penetrating ammunition would start to resonate in the asteroid. And that will break the asteroid to pieces. And those pieces can pull near Earth where they can drop to the ground by using return capsules. 

The small-size intelligent rockets can also use in ASAT or killer satellites. The idea of this kind of killer satellite is that it would shoot the lower orbiter satellites with its darts. And then it would push those satellites back to the atmosphere without breaking their core. The internal artificial intelligence makes it possible that the satellite can search the target satellites without communication between it and ground stations. So the satellite can be silent when it approaches its target and shoots the impact vehicle to it. 

When we are thinking about the kinetic energy systems that are just pushing asteroids away from the trajectory those systems might be useful for the killer satellites. If the satellite shoots the target by using the gel or some other impact cushion that keeps the target in one piece. 

But it makes it fall to the ocean. Keeping the target satellites in one piece is a very good idea because that keeps the orbiter clean from the debris. The killer satellites are suitable systems for destroying enemy communication and recon satellites. Also, things like orbiter lasers can turn away from their course by using the pushing impact ammunition. The rocket will simply push the laser weapon to the atmosphere.

Clementine lunar probe and the strange backgrounds of that spacecraft

Clementine spacecraft

In 1994 United States launched the new space probe to the Lunar Orbiter, and that probe got the name "Clementine". It was the first lunar mission of NASA after Apollo, and there were used many new kinds of sensors like CCD-cameras and another kind of systems, like radar, what mission was to look for the water on the moon. The clementine had the strange background because it was made by NASA and  BMDO (Ballistic Missile Defense Organization). 


The BMDO existence in this project has caused many rumors, that the real purpose of the "Clementine" mission was to look for Russian missiles or some other installations from the surface of the Moon. And the top of those rumors was of course, that the mission was made for locating the alien base from the Moon, and then the base could be intercepted by missiles, but this was of course only one hypothesis. 


There were many things, what was kept secret in the "Clementine" mission, and one of them was the reason, why BMDO took part in this project? Was there somebody, who believed, that there were sent secret nuclear weapons to the Moon by the Soviet Union? The nuclear systems could have the similar shape with Luna 16 probes, but I certainly hope, that those special nuclear missiles are only fiction. The Moon would be the perfect place for remote-controlled nuclear missiles, that can launch to the Earth and their targets by using remote control. The guidance of those weapons would be done with television and joystick. Or the warhead can use the image-identification system, what is brand new guidance method because it needs a quite much computer power. 


The reason, why BMDO was involved in this project is the mystery because that organization mission is to plane the ballistic missile defense tools like ABM-missiles and directed energy systems against ICBM. Above the text is a picture of "Clementine", and that spacecraft claimed to be different, and the real "Clementine" is mentioned be the football-shaped spacecraft, what would be covered the solar panels and light cells. The mission of those light cells would be that they can make 360 degrees image for the probe, what can use as the kinetic energy ammunition. 


Why I expect that is the vegetable "Clementine" is the ball-shaped thing and the spacecraft should have some connection with their names. And maybe the real "Clementine" was the ball, what mission was to demonstrate the way to make similar visibility as the bugs have. Another thing, what might be demonstrated could be, that could the CCD-chips replace the normal silicon panels, what makes the spacecraft more compact than using traditional structure. If the solar panels could also work as the cameras, they could warn the space probe incoming micro-meteorites.
