Atmospheric Subsystem

These spacecrafts are used to study the atmospheric condition of other planets and record the data. They are designed for a relatively short mission. The spacecrafts are carried to their destination by other spacecrafts. The atmospheric spacecraft separates from the main spacecraft when it approaches close to the planet. It is equipped with an aeroshell so as to protect it from atmospheric entry and a parachute to slow its descent. Data recorded is sent to the mother-craft where it is stored and later transmitted to earth.

Balloon package are atmospheric spacecraft and are equipped with a buoyant bag to float with the wind. It is used to study wind circulation patterns.
