Questions & Answers about Il y a moins d'apesanteur et plus de radiations sur Mars.

Why is it moins d'apesanteur and not moins de l'apesanteur?
Words expressing quantity, like moins (less/fewer) and plus (more), are followed by the preposition de (or d' before a vowel) without a definite article like le or la.
How is the word apesanteur (weightlessness) formed?
It is built with the privative prefix a- (meaning "without") attached to pesanteur (gravity, heaviness). It literally translates to "without gravity" and comes from the root verb peser (to weigh).
Why is radiations plural here, when the English translation uses the singular "radiation"?
When referring to the actual rays, emissions, or particles in space, French prefers the plural les radiations. The singular la radiation usually refers to the scientific process of emitting energy, rather than the energy itself.
Why do we use sur before Mars?
Planets take the preposition sur (on). Unlike countries or regions which usually take en or au, planets are treated as physical surfaces, so you say sur Mars or sur la Terre.
