High-Level Project Summary
Our target is increasing the distance that the balloon can reach to 60 Km. The mesosphere has bad weathering: huge storms, strong rains, and low temperature. From previous researches, the material of balloon can bear these changes, but we want to strengthen the material of balloon to avoid risks. We made layer of graphene under the layer of nylon laminated to polyester can withstand enormous pressures, much higher than those at the bottom of the deepest ocean about 200 times stronger than steel.Second method: we increase the temperature of the gas inside the balloon, it leads to increase the volume of the gas. When the volume increase and gas extend it makes balloon reach higher altitudes.

Detailed Project Description
we decided to work on this challenge to make some modifications to increase the quality of Stratospheric balloons and increase their tasks in space by increasing the distance that Stratospheric balloons can reach to allow it explores other phenomena.
Our target is to increase the distance to 60Km, reach to mesosphere layer. The differences between the stratospheric layer and mesosphere are in weather conditions. The mesosphere has bad weathering: huge storms, strong rains, and low temperature. We want to strengthen the material of the balloon to bear the huge internal pressure at a 60Km distance to avoid risks. We made a layer of graphene under the layer of nylon laminated to polyester that can withstand enormous pressures, much higher than those at the bottom of the deepest ocean about 200 times stronger than steel.
Graphene is a tiny balloon made from the one-atom-thick carbon material.
Second method: we increase the temperature of the gas inside the balloon, which leads to an increase in the volume of the gas. When the volume increase and gas extend it makes the balloon reach higher altitudes, according to Archimedes’ principle.
Space Agency Data
we used the website of NASA to recognize the challenge, know more about high altitude balloons, recognize the mechanism of HAB, and laws that are used to make HAB. we also used it to know the parts of high altitude balloons and the function of each part. it inspired us by knowing more details about the materials that are used for making HAB, we identify the cons of HAB, so we start to think of ways to increase the efficiency of HAB by increasing the distance that it can reach (from 45Km to 60Km), and increase the strengthening of the material of the balloon.
Hackathon Journey
it is a useful experience, each of us gains new information. we learn more about satellites and high-altitude balloons.
there are two reasons that inspired us to choose this challenge:
1- It is the cheapest way to reach near space, it cost 10% of the satellites’ budget to reach space.
2- Saving time, it needs days and few weeks to complete its expedition in space unlike satellites, which need months to finish its expedition.
we worked on two methods to modify HAB:
1- Increasing the strength of the balloon to bear high internal pressure at long distances far from sea level, by adding a layer of graphene inside the balloon.
2- increase the distance that the balloon can reach to to allow it explores other phenomena, by increasing the volume of helium gas inside the balloon.
Most problems were in the values of density, pressure, and temperature. we try to solve all these setbacks and challenges by using Ballon Performance Calculator to have accurate values.
