Overview and Mission Statement
Mission Statement: To ascertain how blood reacts to a near space environment.
We wish to test the conditions under which blood boils in a near space environment, based on previous tests recorded on the Internet. We understand that safety is imminent for individuals traveling to around 100,000ft., and therefore must test what will happen to blood in the body if there is an accidental rupture or tear in a pressure suit at this altitude.
Through this experiment we plan to discover the differences between slowand abrupt releases of pressure on blood at around 85,000ft.
Hardware Required
We plan to use a basic stamp BS2-IC which has 16 input output pins for multiple switches motors and servos and can withstand temperatures from -40°C to 85°C, servo controlled valves for exposing the blood to different pressures, blood containment equipment to encase the blood and the tubes to prevent spilling and contamination, polycarbonate sheets that can withstand temperatures from -100°C to 120°C and incredible impact forces, a HOBOdata logger for storing and recording internal and external temperature, two still digital camerasused to take pictures of the outside environment of near space and inside the satellite to monitor the blood experiment, an external heat sensor which will be integrated with the HOBO system, a heater to keep the internal temperature above 0°C and keep the blood from freezing, foam core will provide the overall external structure and support, plastic tubing will be used as a protective layer for the flight string being strung through the center of the balloon sat, plastic tubing will be used as the main structural column through the center of the balloon sat and will house the flight string, and other electrical components such as switches, LEDs, wires, timing circuits transistors, capacitors, etc.

Testing
We will be doing the mandatory tests such as the whip test where we swing the satellite around and test if it will survive the flight, the drop test where we will drop the sat from a height of 15ft. to test a 10mph impact, the cooler test where we see if the internal temperature of the balloon sat stays above 0°C, the subsystems test to check the programming accuracy of the basic stamps and determine that everything is integrated properly, the functional test to see if the balloon sat continues to function, the mission simulation to test if the balloon sat will complete everything that it is supposed to do, and the drag test to see if the structure will withstand the landing of the balloon sat. Besides mandatory tests, we’ll debug the program, and test mechanical aspects rigorously.
Launch Program
We will run through a safety check list to make sure every component of our balloon sat is working correctly. Then we must put the flight string through the center of the balloon sat and secure it to the string with a knot on each of its sides. We will activate the systems by turning on a series of switches.A designated member of the team will then hold the balloon and run along with it until the satellite has successfully left the ground.
Safety
To ensure the safety of all individuals on the team and those around us, we will make sure that the blood stays in the container, wear surgical gloves at all times around the blood, keep a first-aid kit ready, and wear safety goggles when necessary. No horse play will be allowed around tools or the balloon sat. Special care will be takenaround power tools, the soldering iron, and the hot-glue gun. Also, we will make sure to pay attention to the task at hand without risking the safety of ourselves and others by overreaching our abilities by multi-tasking.
Special Features
Our balloon sat will have a 360-degree camera, polycarbonate observation dome, and blood testing equipment. The 360-degree camera will be a regular still digital camera that will rotate in a complete circle taking multiple pictures that can be stitched together to create a panoramic view of the sky. This camera will be housed in a transparent polycarbonate dome protruding from the bottom of the balloon sat. The polycarbonate dome will protect the camera and stay intact upon high velocity impacts with other balloon sats and the ground as well as provide an unobstructed 360-degree view of the horizon.
Events on Launch Day
On the morning of launch day we will wake up, to be ready by 5:15. We will bring the satellite and any extra parts that we might need. Before Launch we will go through a safety checklist, then, switch the satellite on and make sure it works. Finally launch our satellite. Once the satellite lands retrieve satellite and take it back to campus. Last, retrieve the data and analyze the information.
Schedule

Thursday, October 12, 2006 – Prototyping of the structure will be completed.
Thursday, October 26, 2006 – Have balloon sat flight ready and starting tests.

Saturday, November 11, 2006 – Have all systems working and debugged. Flight-ready.
Requirements
1)Our payload will consist of vials of blood that we will expose to different atmospheric pressures, discovering at what altitude blood boils.
2)Our second camera will be a 360-degree panoramic camera.
3)We’ll have spare parts and extra blood so the mission can be ready to run again.
4)We’ll use a plastic tube running through the center of our box and tie knots in the rope to prevent sliding.
5)Will use three 5 watt ceramic resistors, and hand warmers.
6)Our mass of 780 grams is less than 800 grams.
7)The GPS will give our altitude.
8)Our design includes space for one 68x48X19 Hobo.
9)Design includes the external temperature cable.
10)Our balloon satellite will be made of foam core
11)The flight string will run through the center of our balloon satellite and dome.
12)$226.02 is the cost of our project, below the $275 limit for the mission.
13)There is $48.08 left for spare parts out of the cost limit.
14)Contact information, Flag, and Biohazard symbol will be on the side of balloon satellite since it contains blood.
15)Our units are metric.
16)Based on our schedule the satellite will be fully operational by launch day.
17)Use common sense, and seek professional advice of experiment.
18)We’ll have one accountant who will buy all the equipment, keep the receipts, and manage the budget.
19)We’re using blood.
20)Blood isn’t a complete living thing so technically we aren’t sending any major living things in our balloon satellite.
21)We’ll have a video camera on launch day.
