FoundationWhat is a spacecraft flyby?
Need a small nudge?

The name suggests passing a target rather than staying around it.

UnderstandingWhat is a major advantage of an orbiter compared with a single flyby?
Need a small nudge?

Think about what becomes possible when a spacecraft remains gravitationally bound to the target.

ApplicationA planet is hidden beneath thick, persistent clouds, and scientists want to map its solid surface from orbit. Which technique is especially useful?
Need a small nudge?

Choose a technique that can penetrate cloud cover more effectively than ordinary visible-light imaging.

InterpretationA spacecraft records how sunlight reflected from a planetary surface varies with wavelength. Scientists want to identify minerals in that surface. Which method are they using?
Need a small nudge?

Minerals interact with light differently at different wavelengths.

ConnectionScientists want both a global map of the surface beneath a cloud-covered planet and direct measurements of how its atmosphere changes with altitude. Which mission concept best matches both goals?
Need a small nudge?

Match each scientific goal to the tool that can answer it: hidden global surface and vertical atmospheric profile.
