Flight Manifest
The flight team consists of a total of six fliers divided between two flight teams. The
team members consist of students Ryan Darnell, Aaron Cranmore, Nolan Rap, Cody
Muchmore, and Dahmahnic Mace-Nocera and teacher Paul Fechtmeister. All team
members are first time flyers aboard the reduced gravity aircraft. There will be a ground
crew consisting of Karen Wagner, Georgia Moran and Thomas Bilodeau. The flight date
is April 5 & 6, 2011.
2.0 Experimental Background
The experiment is being flown as part of the High School Students United with NASA to
Create Hardware (HUNCH) program. It was designed, fabricated, and documented by
the students at East High School in Cheyenne, Wyoming. The reason for doing the
project is to determine the differences of rates of diffusion of a volatile organic
compound (VOC) in microgravity conditions compared to 1G. The experiment will test
the rate of diffusion of a volatile organic compound and the direction of diffusion under
microgravity conditions. The students will record the measured voltage from Figaro
TGS2602 general air contaminant sensors that are placed within a Lexan box and are
exposed at various distances and directions to a volatile organic compound. The rationale
for this experiment is to determine the nature of diffusion of volatile organic compounds
in microgravity in order to understand how scents will disperse on the ISS.
3.0 Experiment Description
3.1 Diffusion of Volatile Organic Compounds in Microgravity Background
The experiment was based on the idea that liquids diffuse differently in microgravity and
therefore, so will gases. The Rose Experiment that flew on shuttle in 1998 on STS-95
found that a rose sent to space produced a different scent than it did on earth according to
observers. The results of the Rose Experiment indicated that in low gravity the rose
actually produced fewer volatiles than it did at 1G.

3.2 Design
The experiment is contained inside a box constructed from Lexan, which will be placed
inside a NASA Reduced Gravity Office Glove Box to provide the double containment
and eliminate the need for a stress analysis. The experiment relies on Figaro volatile
organic sensors attached to a sensor board that reads changes in voltage across the
sensors when volatile organic compounds are sensed. A base for the Lexan box that
contains the sensors is constructed so that the box can be positioned horizontally,
vertically and at a 45 degree angle. There will be a fan at the top of the box to eliminate
the scent after each parabola. Pellets of charcoal will be used to help absorb the VOC
from the glove box. A Vernier LabQuest will be connected to the sensors and velcroed
inside the glove box to record data from each sensor in the box. The VOC will be
contained in sponge, contained in a sealed cavity away from the sensors at the bottom of
the box.

3.3 Hypothesis/Purpose
The purpose of this experiment is to determine if the rate of diffusion of a VOC varies
when measured in a gravity field as opposed to a zero gravity or microgravity
environment. Different orientations will be studied in order to better discern the
subtleties of diffusion rates. We think that in a reduced gravity environment, the VOC
will diffuse faster than in the effects of Earth gravity, because the VOC has mass and
may be visibly measurable with our sensors
3.4 Experiment Goals
Our experiment during reduced gravity periods will test the rate of diffusion of the VOC
for 3 different distances from the VOC and in 3 different orientations (horizontal,
vertical, and diagonal).
We will observe the readings of the voltage meter during reduced gravity conditions to
get accurate timings of when the sensors detect the VOC.

4.0 Equipment Description
The following is a list of the equipment that will be brought onboard the aircraft. All
equipment for takeoff and landing except for the charcoal container will be stowed in the
cargo container. During the parabolas all equipment will be stowed in a NASA approved
glove box for the entire flight except for the Vernier LabQuest which will be velcroed to
the glove box. Total weight of all system components for the experiment is
approximately 9 lbs, with charcoal weighing approximately 4.4 lbs. The final experiment
weight will be updated at the Test Readiness Review.

11.0 Hazard Analysis Report
The hazards associated with the experimental design are that the VOC (100% Cedarwood
oil) vapors can leak out into the plane’s cabin causing a scent that spreads throughout the
aircraft. The VOC liquid form has a flash point of greater than 93 degrees Celsius
according to its MSDS. If heated properly it becomes a combustible liquid. The results of
this hazard occurring would mean VOC could combine with a fire and aid it. Since the
15
components are always contained within the glove box there should be no threat to the
cabin environment. (Please see Hazard Analysis Appendix starting on page 19)

TEST PURPOSE
PURPOSE
The purpose of this document is to identify potential hazards associated with the
experimental protocol and hardware of the “Column Scents” experiment. This
experiment is being flown as part of the RGSFOP. This experiment was designed by the
students at East High School in Cheyenne, Wyoming as part of the High School Students
United with NASA to Create Hardware (HUNCH) program
A "hazard" is defined as any condition that has the potential for harming personnel or
equipment. As the experiment is carried out in hyper and microgravity fields, it is
important to minimize potential risks to the hardware and personnel.
SCOPE
This hazard analysis covers the hazards of handling and operating the experiment during
ground and flight operations. In addition, this analysis covers the general procedure
associated with the experimental protocol.
The following inputs were used to complete the Hazard Analysis documented in section
15.0 of the report. As mentioned above the classifications are also documented in
Johnson Space Center Document, JSC-17773.
SYSTEM PURPOSE
The experiment is being flown as part of the High School Students United with NASA to
Create Hardware (HUNCH) program. The experiment will test the diffusion rate and
direction of a VOC in microgravity. The students will observe and record the readings
from Figaro VOC sensors.
21
SYSTEM FUNCTIONAL DESCRIPTION
The experiment is contained inside a box constructed from Lexan, which will be placed
inside a NASA Reduced Gravity Office Glove Box to provide the double containment
and eliminate the need for a stress analysis. The experiment relies on Figaro volatile
organic sensors attached to a sensor board that reads changes in voltage across the
sensors when volatile organic compounds are sensed. A base for the Lexan box that
contains the sensors is constructed so that the box can be positioned horizontally,
vertically and at a 45 degree angle. There will be a fan at the top of the box to eliminate
the scent after each parabola. Granulated charcoal will be used to help absorb the VOC
from the glove box. A Vernier LabQuest will be connected to the sensors and velcroed
outside the glove box to record data from each sensor in the box. The VOC will be
contained in sponge, contained in a sealed cavity away from the sensors at the bottom of
the box.
