Abstract

Abstract 1:

Jennifer Jo Burden

UVA and UVB

The NASA Balloon Satellite, which is a balloon that is sent 100,000 feet into the upper atmosphere to collect data, and stream that data live to NASA webpage, will carry experiments that are part of a payload. My experiment will be a Neulog Sensor Logger that will collect data on the UVA and UVB exposure rate of light from the upper stratosphere and on the ground. Data measuring the exposure rate of the light will also be collected from robot welding cells or sections in which one robot will be measured in comparison to the six robots in another cell. The theory is that the UVA exposure does not change from the upper stratosphere to earth nor does the UVA exposure change no matter the number of robots. The UVB rays should decrease in exposure rate of the light as they enter into Earth’s atmosphere unlike the UVA. The significance with UVA and UVB radiation is that in dangerously high levels of radiation can cause damage to the cornea of the eyes.

The Effects of Low Atmospheric Pressure on Blood Chemistry and Cell Structure

The purpose of this research experiment is to study the effects that a large change in atmospheric pressure has on blood chemistry and cell structure. In this experiment, canine blood is being sent to near-space on a helium filled balloon for approximately two hours, and then parachuted back to the ground when the balloon bursts at an approximate altitude of 100,000ft. The blood will be kept from freezing to eliminate any effects of hemolysis (the bursting of blood cells) from this cause, as the lowest temperature reached is below -50oC. Two tubes of blood will be sent to near-space and two will be kept on the ground as controls. One of the tubes sent to near-space and one of the controls are for studying the changes in the blood’s cell structure and are in vacuumed sealed tubes containing an anticoagulant. The other two tubes are for studying the changes in the blood’s chemistry and are in vacuumed sealed tubes containing a different anticoagulant that is more suited for studying the blood’s chemistry. The blood will be analyzed at a professional laboratory for any changes or abnormalities. No changes are anticipated in the blood’s chemistry, but there may be shrinkage or rupture of the blood’s cell structure due to low atmospheric pressure.
