Purpose of the flight and payload description
This balloon flight has been carried out under the umbrella of the Honghu Special Project (Near Space Science Experiment System) a strategic pilot technology program launched by the Chinese Academy of Sciences on March 2018. It focuses on the exploration and study of the near space environment, and relies on multi-type platforms to carry out the comprehensive detection of the near space with the most complete range of parameters possible.
Combined with multi-source data, the objective is to deeply describe the atmospheric environment, electromagnetic environment and radiation environment in the near space, and greatly improve the cognition and prediction of such realm. The aim of the program includes carrying balloon-based experiments in physics, chemistry, biology, optics, planetary space environment and remote sensing detection.Most of the balloon flights under the initiative made use of multi-instrumented platforms on which were performed experiments for all the disciplines mentioned above in a single flight.
Balloon launch operations are in charge of the Aerospace Information Research Institute.
