Mission Overview
Purpose: Study the feasibility of using superhydrophobic materials in the presence of high acceleration and vibrations for possible use on space missions.
Run an experiment for American Semiconductor Inc.
Mission Overview: Theory
When water is in contact with the superhydrophobic surface (diatomaceous earth) it is more attracted to its own surface tension than it is to the material. This is because the material works like a microscopic bed of nails. Diatomaceous earth is a new material developed by John Simpson at Oakridge National Laboratory and is exceptional due to its high contact angle with water and low price.
Mission Overview: Benefits
The goal of this launch is to prove that this diatomaceous earth can survive a rocket launch and still be functional post-flight.
This material could have many different benefits if it is shown to survive space travel. The SH material has already been shown to work in microgravity by NNU and NASA’s Reduced Gravity program. It is now being hypothesized that this material could reduce water entrapment in space craft piping or be able to separate liquids from gas without the need of moving parts.
Mission Overview: Success
Minimum success criteria: For this mission to be considered a success, the SH material needs to be recovered and tested post-flight.
Mission Overview: Concept of Operations
Due to most of the testing being done pre-flight and post-flight, during the flight the material just needs to stay contained. A g-switch will activate the accelerometers and American Conductor’s board which will both run for the entire duration of the flight.
Mission Overview: Expected Results
It is hypothesized that the material will survive the high acceleration and vibrations and still be functional in post-flight testing.

Budget
Item Amount Budgeted ($)
½ Can $7000.00 paid by American Semiconductors
Superhydrophobic Material Made by NNU for less then $50.00
Travel Funded by Idaho Space Grant
Facilities Provided by NNU
Preliminary Schedule
In contact with American Semiconductor to find out exactly what they want to send up.
The size of their plate will then determine exactly how much superhydrophobic material can be sent up.
Construction will then begin.
Important Notes
A double containment system will be used to make sure the pure water will not go into the rest of the canister
Our work with American Semiconductors will determine the specifics of the superhydrophobic experiment
Conclusions
Superhydrophic material is new and largely untested.
The possible application for future space missions makes this experiment on a rocket very valuable.
This experiment will not only provide valuable data on the superhydrophobic material but also help teach students how to do real research.
