Questions addressing the energy requirement for space/orbit/interplanetary missions.

All missions are limited by the amount of energy available to the vehicle, and mission instruments. This is particularly acute in spacecraft because of the large amount of energy needed to make it to the edge of Earth's atmosphere.

Sources of energy may be

  • Chemical E.g. Battery
  • Nuclear E.g. RTGS
  • Solar E.g. Photovoltaics

When a question or it's description addresses or attempts to address acquiring/fulfilling the energy requirements of

  • Mission propulsion
  • Mission instruments
