How did the probe accelerate that 2-kg lump of copper to 7,200 km/h (2 km/s)? Just asking if someone happens to know, didn't see it mentioned.

- Sharlin 7y agoThe impactor device was very similar to a HEAT warhead; a high explosive shaped charge lined with copper. Detonation of the shaped charge turns the copper lining into what's called an explosively-formed penetrator of EFP [1]. Note that the device was separated from the main probe before use and the probe itself was below the horizon when the impactor was fired in order to avoid damage from debris.
