It seems like you want to discredit NASA now ("shouldn't melt") vs some imagined possibility("won't melt" but it does). With the amount of design, analysis, testing, and independent review and verification of the systems, backup systems, triply redundant systems, and autonomy, we can be as sure of it not melting as we can be sure of anything. And we certainly spent a large amount of money on this (about 1/10th of the World Cup), but in performance and value per $, it's a great deal.
