6 FAQs about [Electrical power systems for unmanned spacecraft]

Why do we need a space power system?

NASA’s future missions of science and human exploration require abundant, reliable and affordable energy generation, storage and distribution. Power needs grow exponentially as we look at extending human presence beyond near earth. Problem: Today’s space power systems limit our ability to conduct human exploration beyond LEO.

Can a spacecraft use a live electro-explosive device?

Except for bridgewires, live electro-explosive devices (EEDs) used to initiate such spacecraft functions as boom and antenna deployment shall be replaced by inert EEDs. When that is not possible, special safety precautions shall be taken to ensure the safety of the spacecraft and its operating personnel.

What are the key driving requirements for spacecraft power systems?

Current spacecraft power systems key driving requirements become even more critical as we look at meeting growing power needs. Custom systems created from one-of-a-kind components. Limited or no growth potential. Require extensive infrastructure for verification and operation. Limited or no autonomous operation.

How should a spacecraft data system be designed?

The spacecraft data system shall be designed to protect critical data from loss in the event of selected anomalies (e.g., transient power outage). The design process should include an analysis showing that protected critical data is transmitted to Earth after an anomaly as soon as practical.

Can a model spacecraft be considered a system?

Model Spacecraft W ith Subsystems Although the emphasis is at the spacecraft or system level, if a single assembly or experiment is relatively large , it also could be considered as a system, and the grounding architecture considerations discussed here could be applied to it separately.

How should support equipment be used to test a spacecraft?

Support equipment used for testing the spacecraft should be constructed to maintain the grounding architecture for the spacecraft. In general, all interfaces between flight hardware and support equipment should be isolated. 4.5 Heritage Spacecraft . Spacecraft programs studied to establish these guidelines include those listed in table V.
