Joseph Prahl, an alternate payload specialist on STS-50, has passed away 19 April 2018. He was 75 years old. His association with Cleveland’s NASA Glenn Research Center began in 1970; he took a leave of absence from the university from 1990 to 92 to work as a payload specialist at NASA Marshall Space Flight Center in Huntsville, Alabama.That included the 13-day Columbia mission in June 1992, when Prahl helped with more than a dozen experiments in areas such as crystal growth, fluid physics, combustion, bioprocessing, space-acceleration measurement and the effects of extended duration orbit on the human body. He also assisted in experiments in combustion, surface tension, droplet dynamics and crystal growth. His background in surface-tension-driven flows and combustion played a role in his selection by NASA as a payload specialist for the mission. His NASA work wasn’t limited to Columbia. He also worked with support from NASA Glenn Research Center on studies in tribology and oil-free turbomachinery; in the chemical kinetics of hydrogen-oxygen and propane-air systems; and in the use of mechanical seals for turbomachinery and space craft docking systems. |

This is sad news. A few years back when I knew I was visiting Cleveland, OH I contacted Professor Prahl about visiting him at CWRU. He replied quickly, that he could not meet because he spent his summers on his boat in Lake Eerie. Nevertheless when I was in Cleveland, I popped by the university and saw where his office was. He had many pictures and decals of his space activity. One included Georgi Grechko who I think he had met or even worked with on an experiment. Seems like he was well respected and very well liked at the University. Great professors, never retire, just carry on until the end. Still a bit too soon. RIP. |

Joe was one of my professors during my undergraduate years at Case Western. He was instrumental in ensuring that I graduated on time with my class after a scheduling snafu threatened to extend my time at Case. For that alone, I am eternally grateful. Later, after I entered the space industry, our paths crossed again and I enjoyed resuming a collegial relationship at the professional level. Joe was always easy-going and approachable. He was one of the good guys. I will miss him. |
