Requirements for lunar and deep space exploration

1 Scope

China's national requirements for piggyback payloads carried on lunar and deep space probes. A piggyback payload rides on a mission whose purpose is something else - an instrument, a small satellite, a technology demonstration - and gets to deep space for a fraction of what its own launch would cost. The arrangement has produced a great deal of science, and it creates a specific engineering relationship that these requirements govern. The host owes the payload an interface, a mass and volume allocation, power, data and a release or operation opportunity. The payload owes the host the guarantee that it will not endanger the mission: that it cannot draw more power than allocated, cannot interfere electromagnetically, cannot outgas onto the host's optics, cannot shift the centre of mass unexpectedly, and above all cannot fail in a way that propagates. The last is why the requirements exist as a standard rather than a per-mission negotiation.

This document specifies the general requirements, mission division, Requirements for onboard input documents, onboard workflow, interface safety requirements, and possible pressure vessels, batteries, radioactive sources, and propellers. Safety requirements for hazardous sources such as propellants and pyrotechnic devices. This document applies to the mission matching, interface coordination and safety control of the lunar and deep space probe payloads. It is used for reference in carrying on other space vehicles such as global satellites.
