6 FAQs about [Asteroid deflection space based solar power]
Can a multi-spacecraft system deflection a asteroid?
This paper presents the design of a multi-spacecraft system for the deflection of asteroids. Each spacecraft is equipped with a fibre laser and a solar concentrator. The laser induces the sublimation of a portion of the surface of the asteroid, and the resultant jet of gas and debris thrusts the asteroid off its natural course.
Can a solar spacecraft deflect an asteroid?
It also enabled the performance of a space-based laser system to be reassessed. The capability of a moderately sized, conventional solar powered spacecraft was evaluated by its ability to deflect a small and irregular 4 m diameter asteroid by at least 1 m/s. Deflection had to be achieved with a total mission lifetime of three years.
Can solar energy be used for asteroid deflection?
The strategies of using solar energy for asteroid deflection have been proposed in past studies. A well-known one is a solar collector, which deflects an asteroid by focusing sunlight onto its surface and sublimating the surface material to generate thrust [ 2, 17 ].
Can a solar pumped laser be used to deflection asteroids?
Conclusion This paper presented the multidisciplinary design of a formation of spacecraft equipped with solar pumped laser for the deflection of asteroids. The paper demonstrated that the use of multiple spacecraft is an optimal solution to maximise the deflection while minimizing the mass of the overall system.
Can laser ablation be used to deflection near Earth asteroids?
Analysis gained from a series of experiments has demonstrated the effectiveness of laser ablation for the low thrust, contactless deflection and manipulation of Near Earth Asteroids. In vacuum, a 90 W continuous wave laser beam has been used to ablate a magnesium-iron silicate sample (olivine).
What is asteroid de-spin & deflection?
As a consequence of the asteroid de-spin, the attitude of the asteroid is under the control of the attached solar sail. This capability can ensure the effective asteroid deflection/disruption operations proposed in past studies. Fig. 1. Concept of asteroid de-spin and deflection using a solar-sail spacecraft.
