Hints: NASA coordinate William Boynton Martian Mars gamma ray spectrometer

But they never got there. The first disappeared into deep space. Another missed its target when its coordinates were confused. One NASA control center was working in metric, the other in feet and inches, they never lined up and the probe exploded in the Martian atmosphere. William Boynton had lost precious equipment on both missions. But he decided to try one more time.
This is really my third attempt to get to Mars, and some of my colleagues were saying:" Bill, are you crazy? You are doing a third time? You know, why are you putting so much time into this?" And I just, I just couldn't say no, I, I think there was just a calling that I had to go back.
So once again, he set about designing an instrument to detect underground water on Mars. After the previous failures, the pressure was on.
The role my instrument has taken in the search for water on Mars is we have a device called a gamma ray spectrometer and it's designed to determine what elements are present on Mars that make up the surface, and probably the most important one of those is hydrogen 'cuz that's the main constituent element in water.
