As mentioned in this question the total budget of the Lunar X-prize was about US \$30 million, and that included some other prizes beside the winner. However the budget of Beresheet post-X-prize candidacy rose to about US \$95 million.
I'm guessing that the X-prize candidate mission's budget was targeted to roughly the size of the prize (though I could be wrong). Since then, what additional capabilities or factors have contributed to the final size of the budget? Is it just that the US $95 million is more realistic, or does the new mission include new thing, or are there other factors?
