Miss Cheryl Peltz, high school student from Littleton, Colorado, discusses her “Cytoplasmic Streaming in Zero Gravity” experiment with Ed Armstrong (left) of the NASA Manned Spacecraft Center, and her advisor Charles Cothran (right) of the NASA Marshall Space Flight Center (MSFC). She was one of the 25 winners of a contest in which some 3,500 high school students proposed experiments for the following year’s Skylab Mission. Of the 25 students, 6 did not see their experiments conducted on Skylab because the experiments were not compatible with Skylab hardware and timelines. Of the 19 remaining, 11 experiments required the manufacture of equipment, of which Miss Peltz’s was one.
