Conservation of mass was an equally universally true and fundamental
assumption until a couple of decades ago.

More then that. The rediculasly poor return on such projects. I.E. it could
be decades to centuries to get back any info. Puts them in an uncomfortable
catch-22. If you really want the info, your not going to be that patient.
If your not in that much of a hurry. Why not wait a couple more deacades
(or centuries) for the launches?
