If NASA had that many failures while working on a program explicitly not intended to experience failures and it wasn't being run by Boing, Lockmart or any other defense contractor that has Congress in its pockets, yeah, they'd be getting hell from Congress. But, NASA did used to work on regular old development programs akin to Starship, where perceived failure was completely acceptable to push understanding. For example, there were the Ranger series of lunar impactors, the first 6 of which all failed in various ways, and of course they blew up plenty of rockets and rocket engines back then too. The issue isn't "burning tax dollars". Congress is too busy selling out the country's future to give a shit about that. The issue is that they'd already rather not be giving any money to NASA in the first place. They'd just give the defense contractors tax payer funded 'donations' directly if they could.
