MARSFEVER / LETTERS FROM MARS

MARSFEVER POSTAL AUTHORITY · ROVER CORRESPONDENCE DESK

Your kid has a
pen pal on Mars.

Rusty is a rover — six wheels, one arm, seventeen cameras, strong opinions. He writes your kid letters by name: the blue sunsets, the tiny tornadoes that do his chores, the rock that lived in his wheel for a month. Real Mars science, smuggled inside a very funny robot. Delivered to your inbox, first one free.

MARSFEVER POSTAL AUTHORITY · TRANSMISSION 001 · SENT FROM MARS

Hello Maya! I'm Rusty. I live on Mars.

I'm a rover — a robot the size of a go-kart, with six wheels, one arm, and seventeen cameras. I have been driving around Mars taking pictures and poking rocks, and honestly? Best job in the solar system.

You should know some things about my planet, Maya: the sunsets here are blue (your planet got that backwards). My biggest mountain is almost three Everests tall. I am not allowed to climb it. It gets so cold at night that I dream in penguin.

Mission log: today I drove 40 meters, which is a rover marathon. I found a rock shaped like a slightly rounder rock. Classified it TOP SECRET. You're welcome, Maya.

Grown-up questions

The parent briefing

Where do the letters actually go?
To your inbox, addressed to your kid by name. We never email children directly — you decide when to share each letter, read it aloud at dinner, or print it and "deliver" it yourself.
Is the science real?
Every fact in Rusty's letters is real Mars science — blue sunsets, dry-ice snow, dust devils that clean solar panels, Olympus Mons, sols, Phobos and Deimos. Rusty himself is a fictional rover with a strong personality and a clean driving record (one donut, officially a "calibration maneuver").
What does it cost?
First letter free, and monthly transmissions are currently free while printed editions are in pre-launch. Free subscribers get first invites when keepsakes open.
What ages?
Roughly 5–11, read together at the younger end. The jokes run two layers deep on purpose — one for the kid, one for the grown-up reading over their shoulder.
How do we stop?
Reply STOP to any letter. Rusty will understand. He'll say something brave about it.
