Balloons and Activities ------------------
 A
Helium-filled Balloon Ascending with External Sensors.
This balloon was released from a parking lot in Treynor, Iowa. The sensors
attached to the balloon collect data so that we may plot temperature,
air pressure and relative humidity.
The balloon reaches an altitude of roughly 100,000 feet. This altitude
on earth approximates the air pressure that is recorded on the surface
of Mars! (Check the information on ARES, a Mars airplane.)
The balloon is released from a pre-determined site and the landing location
is calculated by taking into account the wind velocity. The balloon
rises until it finally breaks, begins it's descent and the payload parachutes
to the ground. The payload contains a GPS (Global Positioning System)
unit which transmits back to the search team. The payload also consists
of a temperature sensor, a relative humidity sensor and an air pressure
sensor. The data is collected and analyzed.
Part of the initial problem is to calculate where the balloon will land.
The wind vector will dictate the balloon's flight path. How is this
done? What is important to know? Wind velocity? Wind direction? Make
yourself a practice problem and show how you could explain the balloon's
flight path to a classmate or a parent.
