asteroid deflection

  • Various asteroid deflection strategies have been proposed, as early as the 1960s.
  • A similar application is the proposal to use nuclear explosives for asteroid deflection.
  • All were interested in contributing to the proposed creation of an asteroid deflection capability.
  • It has conducted two lines of related research to help detect asteroids that could one day strike the Earth, and find the technological means for asteroid deflection.
  • The discovery of the potential impact heightened interest in asteroid deflection strategies.
  • The October 2001 asteroid deflection workshop participants created the "B612 Project" to further their research.
  • B612 is one of several organizations to propose detailed dynamic surveys of NEOs and preventative measures such as asteroid deflection.
  • This innovative propulsion technique named Ion Beam Shepherd has been shown to be effective in the area of active space debris removal as well as asteroid deflection.
  • Although various Spaceguard projects monitor the Solar System for objects that might come dangerously close to Earth, current asteroid deflection strategies are crude and untested.
  • Analysis of the uncertainty involved in nuclear device asteroid deflection shows that the ability to protect the planet does not imply the ability to also target the planet, which is the case with all non-nuclear alternatives, such as the controversial gravity tractor technology.
  • The fact that the beam can be generated on a "shepherd" spacecraft placed in proximity of the target without physical attachment with the latter provides an interesting solution for space applications such as space debris removal, asteroid deflection and space transportation in general.
  • In the 2000s the European Space Agency (ESA) began studying the design of a space mission named Don Quijote, which, if flown, would have been the first intentional asteroid deflection mission ever designed.
  • It also assisted the Association of Space Explorers in helping the United Nations establish the International Asteroid Warning Network, as well as a Space Missions Planning Advisory Group to provide oversight on proposed asteroid deflection missions.
  • The space observatory's objective would be to accurately survey NEOs from an orbit similar to that Venus, creating a large dynamic catalog of such objects that would help identify dangerous Earth-impactors, deemed a necessary precursor to mounting any asteroid deflection mission.
  • The European Space Agency (ESA) is studying the preliminary design of two space missions for ~2020, named AIDA (spacecraft) & the earlier Don Quijote, and if flown, they would be the first intentional asteroid deflection mission ever designed.
  • Possible asteroid deflection strategies include "painting" the surface of the asteroid or focusing solar radiation onto the asteroid to alter the intensity of the Yarkovsky effect and so alter the orbit of the asteroid away from a collision with Earth.
  • The Foundation evolved from of an informal one-day workshop on asteroid deflection strategies during October 2001, organized by Dutch astrophysicist Piet Hut along with physicist and then-U.S. astronaut Ed Lu, presented at NASA's Johnson Space Center in Houston, Texas.
  • The foundation also proposes asteroid deflection of potentially dangerous NEOs by the use of gravity tractors to divert their trajectories away from Earth, a concept co-invented by the organization's CEO, physicist and former NASA astronaut, Dr. Ed Lu.
  • He is also responsible of the Work Package on numerical simulations of collisions and asteroid deflection by a kinetic impactor in the European Consortium NEOShield funded by the FP7 program of the European Commission (2012-2015).
