High School Student Eleanor Sigrest Takes a Ride in Zero-G to Slosh-Test Her Space Shuttle Tanks@Raspberry_Pi #PiDay #RaspberryPi
After winning Broadcom MASTERS with her her Zero-G parabolic flight Research Proposal Package, High School student Eleanor Sigrest went to the NASA Goddard Space Flight Center, where she met the scientists who peer-reviewed her project and got to experience zero-g go on her first parabolic flight. Here’s more Eleanor Sigrest from the Broadcom Foundation:
“On my first parabolic flight I experimented with a novel microgravity slosh mitigation technique. This is the research with which I qualified for ISEF this past year. The day before the flight, I conducted a test readiness review with the Zero-G Corporation. Then, I mounted my test apparatus into the plane and powered up the whole experiment to conduct an electromagnetic interference test. On the day of the flight, there was an ID check, then we loaded onto the plane. During the flight, there were 4 “calls”. “On the pull” is a 2-g climb towards the top of the parabolic arc. “Pushing over” is the plane transitioning at the top of the parabolic arc. “Release” is called when the plane achieves microgravity. And “Feet down, coming out” means the plane is exiting microgravity. Once the “Release” call was made, I would wait 5 seconds, then initiate an acceleration to the test apparatus using my push rod. The motion caused the fluid (aka water because hydrazine is extremely dangerous and difficult for a high schooler to get her hands on) to slosh, or move, around inside the tanks. Using Raspberry Pi’s and Pi Camera’s I recorded the sloshing of the tanks to review later. I also used hand-held GoPros as a redundant video collection system.”
