What is lost with Peregrine mission destruction?

The Peregrine spacecraft had its work cut out for itself. It was launched with the goal to become the first private craft to perform a controlled landing on the moon, and had accordingly, carried onboard the instruments to measure the conditions on the lunar surface. “Astrobotic’s current hypothesis about the Peregrine spacecraft’s propulsion anomaly is that a valve between the helium pressurant and the oxidizer failed to reseal after actuation during initialization,” Astrobotic representatives wrote in a statement – as reported by Space.com . “This led to a rush of high pressure helium that spiked the pressure in the oxidizer tank beyond its operating limit and subsequently ruptured the tank.”
