Nuclear Hyper Speed Asteroid Interception Apparatus - HAIV
The work of the second phase of creating a unique spacecraft countering asteroid-type space objects begins. The HAIV program is a NASA program to save the planet from the destructive impacts of large asteroids, which will be able in the shortest possible time to deliver a nuclear charge into space with the subsequent destruction of an asteroid. A nuclear charge will deliver a hyper-velocity apparatus into the asteroid's interior. Once inside the asteroid, a nuclear charge will be triggered, which is calculated by a directed explosion, destroying or shifting the space alien from the trajectory of motion. Shards from an asteroid, as in a popular film, will scatter to the sides, which will minimize the risk of destruction of the planet.
If there are uncertainties and difficulties in the use of nuclear charge, then the nuclear vehicle delivery device itself deep into the asteroid should be the most effective means of combating small and medium-sized asteroids. The technologies used in the HAIV project will make it possible to quickly react to a space threat, unlike competitive projects - no more than 10 years.
The second phase is the development by the HAIV architecture specialists with the capabilities of the NASA project and other organizations. 100 thousand dollars (grant) has been allocated for its implementation. This is one of the 30 projects developed according to the NASA program and received grants to continue development.
HAIV Project Problems
The main problems are the lack of necessary technology. The approximate velocity of the approach of the vehicle to the asteroid is estimated from 10 to 30 km / s. This speed is not enough to defeat an asteroid only by kinetic impact. There is no technology for delivering cargo to hard rock at hyper speeds (the cargo will be destroyed).
Possible Solution
The device has a nasal detachable part, which will become a “cumulative bullet” and pierce the necessary “hole” in the asteroid. This hole will enter the main carrier with a nuclear charge. The estimated nuclear explosion is about six megatons.
prehistory
History starts with the asteroid Apophis. Previously, the fact of approaching was quite keenly interested in the world's population, but to date, almost no one remembers it. But "do not remember" refers to the common population, experts not only remember, but also work on the ability to resist the threat of the destruction of the planet by a space wanderer.
The asteroid was discovered by American astronomers. Asteroid is very dangerous. It is established that Apophis passes every seven years in near-Earth orbit and approaches the planet with each new passage. The estimated time of a possible collision with the Earth is 2036 year. The likely date is 13.04.2036 of the year. It is impossible to establish the exact location of the impact even theoretically, since many parameters and characteristics of both the asteroid itself and its motion are unknown. Even if the collision does not happen, the likelihood of this increases in the next seven years. According to research by NASA experts until the middle of the century, it may occur before 4 collisions of various asteroids with the planet.
The diameter of Apophis is relatively small - only about 300 meters, but the consequences for humanity can be the most deplorable. With a speed of 50 000 km / h, the collision of the Earth will hit 500 megatons. For comparison, the energy of the explosion equals the theoretical detonation of the entire nuclear stockpile. weapons available on earth. All other factors, except for radiation, will also be similar to the triggering stockpiles of nuclear weapons.
At this time, more than 800 space objects are being tracked, some of which are large in size. Collision with a huge asteroid is the complete destruction-destruction of the planet. Today, American experts are confident that the asteroid Apophis could be displaced from the trajectory of movement so that it does not fall under the influence of gravitational forces that can give it direction to the planet.
Other projects
NEO-Shield
European project. The estimated development time is three years. Financing - about 5 million dollars. The project participants are experts from 6 countries. Additional funding from European aerospace enterprises is about 2.5 million dollars. Implementation of the project "in metal" is not provided for. The essence of the project is an asteroid shield around the planet.
Russian projects
Creation of spacecraft reconnaissance and delivery of nuclear weapons on an asteroid. The Kaissa spacecraft is a reconnaissance vehicle for gathering information from an asteroid - chemical composition, structure, movement characteristics. KA "Kapkan" - the delivery vehicle of the KAZ (several warheads) on an asteroid.
Project from the company "SEI" USA
A rather interesting project is the delivery of small autonomous robots, for "biting" into its surface with a further ejection of the rock into space. This should change the asteroid's trajectory.
Infrared telescope from the B612 Foundation USA
Specialists of this non-profit organization suggest installing an infrared telescope in near-earth orbit to search for and track dangerous asteroids with a diameter from 150 meters. Location - 50-250 millions of kilometers from the planet. The time spent in space is about 5.5 years. The result is the detection of 90 percent asteroids. Estimated cost 200 million dollars.
Asteroid's “Paint” - AMTM
International project. Changes in the motion of an asteroid without the use of nuclear weapons. The essence of the project - painting a space object to change its reflectivity. Using the Yarkovsky effect. Apophis Mitigation Technology Mission is a mission developed for the Apophis asteroid. The first phase is the dispatch of a scout to determine the characteristics of the asteroid. The second phase is the dispatch of the apparatus with the equipment for painting the surface. The result is the deviation of the asteroid from the trajectory by 3 degrees.
