A LARGE ASTEROID OR COMET NUCLEUS CAN DESTROY
LIFE ON THE EARTH ANY MOMENT
An example of a global catastrophe that occurred 65 million years ago

It took about 10 thousand years to restore the Earth's biosphere
WE CAN PROTECT HUMANITY AND BIOSPHERE OF THE EARTH
APPEAL TO HEADS OF STATES, ORGANIZATIONS
The threat of catastrophic collisions of asteroids and comet nuclei with the Earth is one of the most serious natural hazards for humanity. A large celestial body impact with our planet can immediately destroy humanity or take it back for centuries in its development. Since a collision of a celestial body with Earth can occur any time, the postponement of elaboration of countermeasures is unjustifiable. Many international and national organizations – the UN, the PACE, the OECD, the World Federation of Scientists, the United States Congress, the House of Lords in Great Britain, the Council of Federation of the Federal Assembly of the Russian Federation, and others – increasingly address this issue.
The current technology level makes it possible to create a Planetary Defense System (PDS) against the asteroid-comet hazard (ACH). The Citadel project is an option for creating an international PDS. The ESTR will constitute a basis for it, which can be created in the 5-7 years. It will protect the Earth from asteroids and small comet nuclei. The elaboration of protection from comet nuclei several kilometers in size will take more time and creation of new technologies.
Annual expenses will be about 1 billion US dollars, which is only one thousandth of the world's amount spent for armament. By cutting these expenses by 0.1 percent, we could use the released money not to destruction, but to saving the humanity.
Thee problem of ensuring protection from the ACH can be considered as a test for mankind’s ability to solve global problems. The PDS could become the first global project of mankind in the third millennium that would turn the Earth into an unassailable fortress – Citadel protecting us from space threats. For this purpose, we must recognise our common responsibility for saving humanity and the Earth's biosphere, as well as cultural, material, and other values, created by the labour of billions of people on Earth throughout millennia.
Asteroids and comets repeatedly collided with the Earth in the past
and every minute brings us closer to the catastrophe in the future.
But we can interrupt the suicidal process in the coming years, if we do not stay idle.
