Mercury was closer to the Sun. Venus is hotter. ARQSI and ARQSA enter a bright cloud world where a thick atmosphere overturns their first assumption.
Age-band production: written specifically for ages 6–9 as a heavily illustrated science-adventure comic. Dialogue, diagrams and panel action carry a large share of the narrative. The issue uses the approved ARQSI and ARQSA designs and a unique Opening Signal rather than reusing Issue 01 text.
Venus shines ahead like a pale lantern. ARQSA: “Second planet. Farther from the Sun than Mercury. Cooler, yes?”
Temperature alarms flash before they reach the clouds. ARQSI: “No. Much hotter.”
ARQSI overlays Earth and Venus. “Venus is close to Earth in size and rocky structure. That is why people sometimes call it Earth’s twin.”
ARQSA: “Twins can grow into very different worlds.”
The ship meets layers of yellow-white cloud. ARQSA: “Surface view: blocked.”
ARQSI: “These clouds contain droplets of sulfuric acid. We stay above and use instruments.”
ARQSI displays sunlight entering Venus’s atmosphere. “The atmosphere is mostly carbon dioxide.”
Heat arrows struggle to escape. ARQSA: “So the thick atmosphere traps heat.” ARQSI: “A powerful greenhouse effect.”
A probe simulation descends. Pressure numbers rise. ARQSA: “The air is not only hot. It is heavy.”
ARQSI: “Surface pressure is about ninety times Earth’s sea-level pressure.”
ARQSA watches a slow rotation animation. “One spin takes about 243 Earth days.”
ARQSI: “Yet Venus circles the Sun in about 225 Earth days. Its rotation period is longer than its year.”
The simulation reverses. ARQSA: “Venus spins opposite the direction of most planets.”
ARQSI: “From the surface, the Sun would rise in the west and set in the east.”
ARQSA sweeps the sky. “No moon detected.”
ARQSI: “Correct. Venus and Mercury are the only planets in our Solar System without natural moons.”
The visible-light camera shows clouds. Radar paints mountains and plains beneath them. ARQSA: “Different tools reveal different information.”
ARQSI: “Radar helped spacecraft map the hidden surface.”
Radar terrain shows broad volcanic rises and winding lava features. ARQSA: “This planet has been reshaped by volcanism.”
ARQSI: “Scientists continue studying how geologically active Venus is today.”
A terrain model rises. ARQSI: “Venus has highlands, mountains, valleys and thousands of volcanic features.”
ARQSA: “A whole rocky world hidden beneath clouds.”
ARQSI shows Earth and Venus side by side. “Both planets have greenhouse gases. On Earth, the natural greenhouse effect helps keep the planet warm enough for life.”
ARQSA: “On Venus, the thick carbon-dioxide atmosphere traps far more heat.”
ARQSA: “Our shortcut was: closer means hotter.”
ARQSI: “Mercury and Venus show why science checks more than one variable—distance, atmosphere, rotation, reflectivity and surface all matter.”
Mercury and Venus appear together on the screen. ARQSA: “One is nearly airless. One is wrapped in dense air. Their temperatures behave very differently.”
ARQSI: “Good explanations survive comparison.”
ARQSA records: “Venus—second planet, Earth-sized neighbour, thick carbon-dioxide atmosphere, sulfuric-acid clouds, hottest planetary surface, slow backward rotation, no moon.”
ARQSI adds: “Do not confuse brightness with gentleness.”
The ship clears the cloud tops. A blue point appears ahead. ARQSA: “Next target?”
ARQSI: “Earth.” A silver route line crosses the page. Caption: “ISSUE 03 — EARTH: THE LIVING WORLD.”
Reader prompts: Why is Venus hotter than Mercury? What makes a scientific shortcut dangerous? Why would radar help scientists study Venus better than an ordinary camera?
