Drop Dynamics Experiments

[On 1 January 2014, J. E. Tohline wrote ...] As I was putting this chapter together, I had difficulty documenting the various drop dynamics experiments that have been conducted by astronauts in various Earth-orbiting (zero g) environments. Here is the relevant information that I have found, to date:

  • Skylab (circa 1973-1974): Experiments showing the fission of liquid drops were evidently conducted during the Skylab 2, Skylab 3, and Skylab 4 missions.

According to the Teacher's Guide mentioned above, the activities shown in the above-referenced films were carried out by three teams of Skylab Astronauts:

  • Space Shuttle Flights (circa 1992): Experiments illustrating the fission of liquid drops were evidently also conducted during a couple of space shuttle missions. The experiments were performed with the aid of a "Drop Physics Module (DPM)" inside the "portable" United States Microgravity Laboratory (USML) that was housed in the shuttle's payload bay.
  • International Space Station (circa 2000):
