A new NASA report describes the potential dangers that electrical environments of asteroids could pose for astronauts in future space missions. NASA scientists are now attempting to create models that will successfully predict dangerous electrical interactions between an approaching spacecraft and an asteroid. The report begins with a brief, surprising description of space rarely seen in official press releases.

It's the same problem with Comets they are negatively charged and will give off a power surge when approached by a positively charged satellite or in the case of the Rosetta mission which will launch a vehicle to land on the surface. The only problem is there will be a transfer of energy between the two differently charged bodies with electricity jumping between the objects damaging the electronics of the lander and maybe knocking it out of commission (another waste of millions) This was first seen to happen with the washing machine-sized "impactor" that collided with Comet Tempel 1 at a relative speed of 37,000km/h,

Preliminary data indicated two successive flashes.

"What you see is something really surprising. First, there is a small flash, then there's a delay, then there's a big flash and the whole thing breaks loose.

The smaller flash was the comet discharging electricity into the impactor. A bit like a welding rod flash.
