The Deep Phreatic Thermal Explorer, otherwise known as DEPTHX, is an autonomous underwater robot that was designed to explore water-filled sinkholes in Mexico. The machine is the brainchild of Bill Stone, an intrepid explorer/inventor who believes we can use such robotic probes to explore Europa, the watery moon of Jupiter. NASA funded the three-year, US $10 million project.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
