Creating a Program to Measure Meteor and Asteroid Impacts

Comets, meteors and asteroids sometimes fall to the ground. Every million years, one or two large cosmic bodies enter the Earth’s atmosphere and crash into the ground or the ocean with a great force. Some of 2,000 large near-Earth objects have orbits, which cross the Earth’s orbit and, theoretically, can strike us. Although the threat is real, the probability of falling of a large asteroid or meteor is negligible.

In the United States, the question about the creation of early warning and prevention programs of meteorite falls has already been raised by scientists, but there were funding issues. In 1991, NASA, at the request of Congress, called for the creation of an international system of survey Spaceguard, and with the help of ground-based telescopes and cameras space surveillance to detect dangerous objects for Earth. The U.S. Congress refused to finance the project in the amount of $10 million per year. NASA is spending $1 million a year for the creation and implementation of smaller search programs, which control about 10 percent of the sky in the month.

What should be done if astronomers discover a large object six months prior to its likely impact on the Earth? According to American experts, when a threat is detected early enough military planners could do the following:

  • Using lasers mounted on the Earth or the Moon cause heating and thus evaporation of gases and steam in the form of reactive stream capable of changing the course of movement of the meteor.
  • Try to break the object with the explosion and change its course.
  • Blow up the nuclear charge near the asteroid to change its trajectory.

European experts offer less bloodthirsty, but more expensive ways to avoid an asteroid apocalypse. One way is to build a space tug, capable of transporting an asteroid or meteor using capture tentacles. There are options of using the giant space sail with the solar wind pressure for changing the trajectory of the asteroid’s movement.

Programs monitor the set of points of objects on the map of uncertain future position of the asteroid, and some of these points may take several different dynamic ways. There are now multiple entries of asteroid positions with a possible risk of collision with the Earth until 2060.

Detection programs of near-Earth objects control not only the near-Earth space for the timely detection of cosmic threats. The dimensions of our solar system are enormous, so there is surveillance for asteroids and comets in the distant approaches as well.

Comets, meteors and asteroids sometimes fall to the ground. Every million years, one or two large cosmic bodies enter the Earth’s atmosphere and crash into the ground or the ocean with a great force. Some of 2,000 large near-Earth objects have orbits, which cross the Earth’s orbit and, theoretically, can strike us.
