Although the article doesn't make it clear, note that even if you set
aside the fact that there's no useful payload, there is *no* proof that
anything was really accelerated to escape velocity. The "two pellets" was
just a statistical guess as to what the explosion of the charge would
probably have accomplished, based on assumptions of uncertain accuracy.
The explosion was observed, yes, but not the trajectories of individual
pellets; there was no practical way to track anything that small.
