PROJECT BAKTERIAK
CLASS OBJECTIVES
• To exceed 100,000 ft.
• To keep the payload under 800g
• To measure temperature and pressure
• To resolve malfunctions from the maiden voyage
• To meet all FAA and FCC unmanned air balloon regulations
• To successfully predict flight patterns
• To maintain an efficient budget
OUR OBJECTIVE:
TO SEND BACTERIA
INTO SPACE
But why?
MISSION STATEMENT
• Commercial Space Travel
• Sterilization of civilians and equipment is impractical
• Predicting bacterial behavior
BACTERIA
BACTERIA INFORMATION
Species:
• Escherichia coli (E. coli)
• Will survive extreme temp. changes
• Facultative anaerobe
• Easily replicated
• Easy to get ahold of
• Safe (is non-pathogenic)
• Practical
• Recommended by Dr. Ty White
• Thioglycollate Broth
OVERVIEW: Test bacteria
after retrieval to find
changes in growth patterns
In the payload
• “Thio” broth E. coli dilution
• 500 microliters
• Plenty of data
• Pure E. coli
Controls
• Freezing during flight
•
•
•
•
Control 1: broth dilution in freezer
Control 2: pure bacteria in freezer
Control 3: broth dilution at room temp
Control 4: pure bacteria at room temp
THE EXPERIMENT
HYPOTHESIS
Based on results from the NASA experiment,
Project MERCURRI, we postulate that the
E. Coli growth rate will be affected by the
drastic pressure and unknown cosmic changes
between the ground and the apex of the flight.
SAFETY CONCERNS
PRECAUTIONS:
• Rubber Gloves
• Medical Masks
• Bleach Baths
• Biohazard Bags
Will the Payload Land Near Civilians?
We will ensure that our payload will not fly
over heavily populated areas using our flight
path predicting technology.
• Biohazard Signs (for payload)
(Donated By Dr. Paul Rezich)
The bacteria species we are using are relatively safe to handle.
Very little danger is involved due to low virulence and pathogenic properties present in the bacteria.

PROJECT BAKTERIAK
IS SENDING BACTERIA INTO SPACE LEGAL?
IS SENDING BACTERIA INTO SPACE LEGAL?
Similar Experiments have been done by organizations such as
NASA and junior high schools successfully.
There are no laws or regulations preventing us sending our
bacteria into space.
BUT IS OUR PROJECT CONSIDERED A BIOLOGICAL WEAPON…?
IS OUR PAYLOAD CONSIDERED A
BIOLOGICAL WEAPON?
No it is not
Definition of Biological Weapon: a harmful biological agent (such as a pathogenic
microorganism or a neurotoxin) used as a weapon to cause death and disease.
Definition of Biological Warfare: the use of harmful living things (such as pathogenic
microorganism or a neurotoxin) as weapons in a war.
(Definitions provided by Merriam-Webster Dictionary)
Additionally…
IS OUR PAYLOAD CONSIDERED A
BIOLOGICAL WEAPON?
Nobel Prize Winner Dr. Joshua Lederberg: a pioneer research geneticist, professor and past president of
Rockerfeller University made a testimony to Committee on Foreign Relations Chair. The following is an
excerpt from an article from the CDC Emerging Infectious Disease Journal (Volume 7, Number 6) that
summarized Dr. Lederberg’s testimony.
(http://wwwnc.cdc.gov/eid/article/7/6/01-0636_article)
“I [Dr. Lederberg] define biological warfare as use
of agents of disease for hostile purposes.”

MEETING FAA REGULATIONS
ELECTRONIC CODE OF FEDERAL REGULATIONS: TITLE 14 - CHAPTER 1 - SUBCHAPTER F - PART 101 - SUBPART D
(E-CRF DATA IS CURRENT AS OF DECEMBER 1, 2014)
§101.33 Operating Limitations:
By our balloon will exceed 2.000 ft. altitude
By using a hotwire system as the secondary cutdown method
By the Meteorological Team ensuring that our balloon will be launched on a clear day
By the Meteorological Team ensuring that there will be little wind to blow our balloon
away only the football field for the first 1,000 ft. of ascent
• By our calculated descent acceleration and payload mass creating an impact force
that is not hazardous to people or personal property
•
•
•
•
MEETING FAA REGULATIONS
§101.35 Equipment and marking requirements
•
•
•
•
•
By using aluminum foil on the payload to reflect radar
By launching between the hours of sunrise and sunset
By using our fishing line and parachute chords that will break at 50lbs
By not using an alternative suspension device
By building a payload that is less than 4lb
• (Therefore we can neglect the weight:surface area restriction)
MEETING FAA REGULATIONS
§101.37 Notice requirements.
• Our representative will be giving the FAA the following information:
• The balloon identification
• The estimated date and time of launching, amended as necessary to remain within plus or minus
30 minutes
• The location of the launching site
• The cruising altitude
• The forecast trajectory and estimated time to cruising altitude or 60,000 feet standard pressure
altitude, whichever is lower
• The length and diameter of the balloon, length of the suspension device, weight of the payload,
and length of the trailing antenna
• The duration of flight
• The forecast time and location of impact with the surface of the earth
• Our representative will meet with the FAA the previous day to the launch.
MEETING FAA REGULATIONS
§101.39 Balloon position reports.
• The SPOT Tracker will give us the GPS coordinates of our balloon and our representative to the FAA will inform
them of the balloon’s position.
• Our representative to the FAA will forward to the FAA the following information one hour before descent:
•
•
•
•
The current geographical position
The balloon position
The forecast time of penetration of 60,000 feet standard pressure altitude (if applicable)
The forecast trajectory for the balance of the flight
• Our representative to the FAA will inform them of the balloon’s last known position if a two-hour window is missed
Our representative to the FAA will inform them when Project Bakteriak’s balloon has landed.

PROJECT BAKTERIAK
WHY SEND TWO TEST TUBES?
• Broth dilution tube
• Tests how the bacteria is affected when it is frozen in its growth process
• Pure bacteria tube
• Measures non-freezing related variables (pressure, gravity, radiation, and others)
• Non-dependent because normally, bacteria is frozen before culturing
