Orbit's Critical Point Does Not Deviate
- Mineral
- Ozone
A satellite is above the terminator.
The terminator is the boundary between day and night on Earth — sunlight and shadow meet there, then separate. When a satellite flies above the terminator, one half is illuminated by sunlight at 120 degrees above zero; the other half is in shadow at 140 degrees below zero. Two hundred degrees difference, happening simultaneously on the same object.
This is the terminator’s most extreme aspect: not warmth and cold, but extremes coexisting. A critical point of an orbital period.
The perfumer watched a satellite launch at Kennedy Space Center. The rocket crossing the terminator takes only minutes, but those minutes’ temperature change exceeds any location on Earth. He said that feeling was not crossing, but “simultaneity” — sunlight and shadow coexisting, like an overexposed photograph.
Orbit, the fragrance, uses aldehydes.
Aldehyde molecular structure is R-CHO — a carbonyl connected to an organic group R. Different R gives aldehydes different scents: R=octyl is aldehyde C8; R=decyl is aldehyde C10; R=dodecyl is aldehyde C12. Aldehydes have a common characteristic: they smell like “air,” like “sunlight on metal,” like “clean cold.”
Clean and cold are two different things, but aldehydes make them one.
Top note is cold aldehyde. Not excessive aldehyde, but extremely low concentration aldehyde — evoking zero degrees but not ice. It is the cleanness in air, not the cleanness of water.
Heart note is paraffin. Paraffin is a product of petroleum distillation, one of the cleanest hydrocarbons. Its scent is “neutral” — neither fragrant nor foul, neither hot nor cold, closest to “absolute neutrality.” In this fragrance, paraffin simulates the satellite’s state on the terminator: not day, not night, but the boundary.
Base note is extremely minute metal. Metal’s scent comes from metal oxide — the film produced when metal reacts with oxygen in air. This film is only a few molecules thick, but it is the first layer of change when metal is exposed to air.
A satellite’s metal shell, in the terminator’s alternating heat and cold, slowly oxidizes. This is its life. Oxidation is time.
