Before Earth, before humanity, before the mission changes everything—ARQSI and ARQSA begin their planetary journey at the small, scorched world racing closest to the Sun.
Age-band production: written specifically for ages 6–9 as a heavily illustrated science-adventure comic. Panels, dialogue and diagrams carry narrative weight, so prose density is intentionally leaner than a conventional chapter book. Use the approved ARQSI and ARQSA character sheets without redesigning their established appearance.
Black space. A thin silver signal line pulses across the page. ARQSI: “Navigation lock confirmed.” ARQSA: “Target: first inner world.”
A cratered planet slides into view. ARQSA: “It looks quiet.” ARQSI: “Quiet is not the same as gentle.”
ARQSI projects the Solar System. “Mercury is the closest planet to the Sun.”
ARQSA watches Mercury race along its orbit. “And it moves fast.” ARQSI: “One trip around the Sun takes only about 88 Earth days.”
ARQSA spins a hologram slowly. “Mercury rotates much more slowly than it travels around the Sun.”
ARQSI: “From one sunrise to the next, a solar day on Mercury lasts about 176 Earth days.” ARQSA: “Two Mercury years for one sunrise-to-sunrise day. That is wonderfully strange.”
The ship passes over sunlit rock. Surface warning bars flash. ARQSI: “Daytime can reach around 430°C.”
ARQSA: “Hot enough to destroy most equipment that was not built for it.”
The ship crosses into darkness. ARQSA: “Temperature dropping—fast.”
ARQSI: “At night, parts of Mercury can fall near –180°C.” ARQSA: “Hot enough to bake. Cold enough to freeze. Same planet.”
ARQSA: “Earth’s atmosphere helps move and hold heat. Mercury barely has an atmosphere at all.”
ARQSI: “It has an extremely thin exosphere—atoms scattered so widely they cannot act like a thick insulating blanket.”
Crater after crater fills the window. ARQSA: “This surface remembers impacts.”
ARQSI: “With little atmosphere to burn up incoming objects and little weather to erase old marks, many craters remain visible for immense spans of time.”
The scanners trace an enormous circular basin. ARQSI: “Caloris Basin. One of the largest impact features on Mercury.”
ARQSA: “A collision powerful enough to reshape a huge region—and leave evidence billions of years later.”
ARQSA scans the sky. “Companion search: none.”
ARQSI: “Mercury has no known moons.” ARQSA: “Then the Sun owns the view.”
A faint field appears around the planet in the ship display. ARQSA: “A magnetic field?”
ARQSI: “Weak compared with Earth’s, but real. Mercury has a large iron-rich core, and motion inside the planet helps generate magnetism.”
ARQSA highlights deep polar craters. “These floors never receive direct sunlight.”
ARQSI: “Some permanently shadowed craters contain water ice.” ARQSA: “Ice on the closest planet to the Sun. Distance is not the whole story.”
ARQSI: “Temperature depends on more than how close something is to the Sun.”
ARQSA: “Atmosphere, rotation, surface, angle, shadow—all of them change the result.”
The ship rises above Mercury. ARQSA: “A small planet can carry big lessons.”
ARQSI: “Observe first. Compare carefully. Never assume one fact explains everything.”
Navigation flashes: NEXT TARGET — VENUS.
ARQSA: “If Mercury is closest, Venus should be cooler.” ARQSI pauses. “That assumption will not survive our next stop.”
ARQSA records: “Mercury—fast year, slow spin, extreme temperatures, thin exosphere, no moons, cratered surface, weak magnetic field, polar ice.”
ARQSI adds one line: “Question every shortcut.”
The ship leaves Mercury’s orbit. ARQSA: “First world complete.” ARQSI: “Twenty-one mission signals remain.”
A new silver line points toward Venus. Caption: “MISSION EARTH — ISSUE 02: VENUS — THE HOTTEST WORLD.”
Reader prompts: Why is Venus hotter than Mercury even though Mercury is closer to the Sun? Why can ice survive in some Mercury craters? What evidence on Mercury tells scientists about its past?
