Possible Using Analysis of Laser Influence on Near-Earth Object.
A space base (a lunar base, in particular) to mitigate the asteroid-comet hazard for the Earth is investigated. The base is proposed to consist of three stations. First, this is an energy station. This station transforms the solar energy into the electric one, which is used to put into operation an astronomical observatory and a laser station. The observatory telescopes can detect near-Earth objects (NEOs) and discover an object, which impacts the Earth during its motion and can lead to the Earth catastrophe. In this case, the laser station is proposed to give a powerful laser effect on that near-Earth object to correct its orbit and deflect it from the Earth or destroy it. There is analyzed this laser effect at the Earth-Moon vicinity. The electric power of the energy station required and the area of solar panels at the energy station are evaluated. Possibility to use new low-energy Earth-to-Moon trajectories with capture by the Moon is shown for creation of the lunar base. Advantages and disadvantages of the laser effect are discussed. Conclusion is made that the international cooperation in designing, creation and operation of this space base is necessary.
