THE SAIL
Two hundred metres of aluminised polyimide, thinner than a soap bubble. Unfurled in silence, it turns sunlight itself into thrust.

SLINGSHOT
The probe falls toward a rust-coloured world and lets its gravity bend the fall into speed — 9.2 km/s stolen from a planet that will never know.
“Trajectory is poetry written in falling. Today we rhymed.”
— Dr. Elena Vasquez, Navigation Lead

THE APPROACH
The sun is no longer a star among stars. It is a wall of white weather, and PERIHELION sails straight into its breath.
- SAIL TRIM +2.0° — THERMAL COMPENSATION
- HULL 412°C — REFLECTIVITY 91%
- FLUX 27× EARTH — CAMERA SHUTTERS 12%
- THERMAL LIMIT 96% — HOLDING
“Every watt it survives is a watt that pushes it faster. The fire is the fuel.”

PERIHELION
Chapter 07 · Epilogue
AFTER THE LIGHT
Contact with PERIHELION was lost 41 minutes after closest approach, as predicted. The last full data frame arrived 8.3 light-minutes later: a spectrum of the corona no instrument had ever tasted from the inside.
The probe did not die there. Models say the sail held. Falling outward now, still accelerating on borrowed starlight, PERIHELION will cross the orbit of Mars in eleven months — mute, whole, and faster than anything we have ever made.
MISSION CONTROL
“We didn’t lose a probe. We gained a comet of our own making.”
Dir. Amara Okafor — Flight Director
“The last packet was clean. She wanted us to know she made it.”
Rin Takahashi — Communications
“Four hundred days of whispers, and the loudest thing she ever said was goodbye.”
Dr. Elena Vasquez — Navigation Lead
“Thermal held to 96 percent. The sail was singing. I could hear it in the telemetry.”
Dr. Yusuf Adeyemi — Thermal Engineer
