Assertion: moon's surface | /r/HasProperty | exposed to solar wind
Facets:
value: directly
type: MANNER
Source sentences:
text: The hypothetical mechanism of water transport / trapping (if any) remains unknown: indeed lunar surfaces directly exposed to the solar wind where water production occurs are too hot to allow trapping by water condensation (and solar radiation also continuously decomposes water), while no (or much less) water production is expected in the cold areas not directly exposed to the Sun.
