Millions of years from now, [[Phobos]] will disentegrate due to tidal forces and form a planetary ring. However, [[Terraforming]] would increase atmospheric drag on Phobos, potentially causing it to collide with Mars. Moreover, Phobos is a problem to the construction of a space elevator.

== Deorbit ==
One solution is to deorbit Phobos and allow it to collide with Mars.

 == Deorbit ==
 One solution is to deorbit Phobos and allow it to collide with Mars. This might be achieved by colliding a small asteroid into it. The initial energy of the asteroid relative to the asteroid belt is 0. An initial kick is all that is needed to move the asteroid into a Phobos intersecting orbit.
-When Phobos impacts the surface it might release a large amount of water ice or carbon dioxide, and this could be a first stage of terraforming. Alternatively, Phobos could kick up large amounts of dust, preventing sunlight from hitting the surface. This could also hinder the production of crops.

 == Boosting into a higher orbit ==
-Phobos could also be boosted into a higher orbit. Solar sails could be considered, but are probably too costly. A gravity tractor is a better idea, as it is not impeded by the rotation of Phobos. However, weather a thuster is a gravity tractor or surface based, it will likely not be powered by chemical rockets due to their inefficiency. An ion engine with sustained thrust over a long period of time could suffice. If there are volatiles inside phobos, such as water ice, they could be vaporised as propellant for a nuclear electric thruster. A mass driver could also be set up on the surface.

Phobos it tidally locked to Mars, making it easier to build a surface thruster and negating the need for a gravity tractor.
