Answer

Brief Explanations:

  1. A satellite is mainly made up of a payload (the equipment for its mission - like cameras or scientific instruments), a bus (the structure that supports and provides power, attitude control etc.), and a launcher is used to send it into space but is not part of the satellite itself. The other options have elements that are either incorrect parts of a satellite or not the main elements.
  2. The loss of the Mars orbiter was due to a calculation units mismatch. One team used English units while another used metric units in the navigation software, leading to incorrect trajectory calculations.

Answer:

  1. Payload, Bus, Launcher
  2. Calculation units mismatch
