Overview & Mission
Statement
Mission Statement: To ascertain how blood
reacts to a near space environment.
To Test:
What are the conditions under which blood boils
in a near space environment?
What if there was an accidental tear or rupture
in a pressure suit around 85,000ft. (~26,000m)?
What are the differences between slow and
abrupt releases of pressure on blood at that
altitude?

Expected Results
A liquid boils when the barometric pressure in
the outside environment equals the vapor
pressure of the liquid. If we can keep the blood
near body temperature, then the atmospheric
pressure at which this phenomenon occurs should
be around 17.5mmHg. The Earth’s atmosphere
reaches this pressure at about 26km. We are
hoping to keep the heater close enough to the
blood so that its temperature will be at or above
37°C. This way, we can see if the predicted
altitude is accurate to calculation. We will find at
what altitude this occurs by comparing data from
our pressure sensor and the photographs we will
obtain during the flight.
