Space flights are risky due to extreme environmental conditions, in addition to the high complexity of rockets, systems and subsystems. Additionally, there are personal and material risks that are due to the rocket launch operation. The cost for the execution of these projects and their respective tests, launching operation and eventual payload recovery, should also being taken in account. The Brazilian Space Agency (AEB) offers the national scientific community opportunities to access space to carry out experiments in a microgravity environment, by launching suborbital rockets. Given that the rate of launches of this type is low, the failures of the payload items cause significant delays in the project development and its constraints, like cost and schedule. This work proposes to apply the STPA technique (System-Theoretic Process Analysis), a method that is a systemic approach to safety analysis, based on the STAMP approach (SystemTheoretic Accident Model and Processes), a predictive risk assessment, to analyze scientific experiments onboard on payloads in suborbital rockets. As results, it is expected obtained safety constraints and recommendations that will contribute to the elaboration of safety requirements applicable to space scientific experiments. It is expected that the availability of systematized information to experimenters in the form of requirements, will contribute to the reduction of experiment failures, as well as simplify the validation process, reducing its subjectivity and interpretation problems.
