Approximately Up Planets & Map Guide

Approximately Up is structured as a slow expansion across a planetary system: you begin on Earth, unlock Planet Stations as permanent garages, and push outward to worlds with different gravity, atmosphere, temperature, and visual hazards (oceans, clouds, thick air). Ship designs that work at home often fail one hop later if you ignore those differences. This guide explains the map philosophy, starting worlds, and how environment stats should drive thruster and sensor choices.

How the map works

You are not warping from a menu. You fly between bodies using ships you build at stations. Each planet typically offers one or more Planet Stations — landing pads with build zones and mission boards. First landing unlocks a station permanently, turning it into a new launch point for future routes.

That loop creates a literal map made of nodes (stations) and edges (routes you can fly). The objective log (press O) points you toward missions that encourage visiting new nodes. Over time your network looks like a spiderweb of garages rather than a linear campaign level select.

Demo players explored a large fraction of the system described in Steam marketing (15 unique planets in store copy). The full release shipped with developer targets around 17 planets — see Demo vs full release for historical scope.

Earth — tutorial gravity, full atmosphere

Earth is the default starting world: familiar gravity, dense atmosphere, and forgiving terrain for first crashes. Atmospheric thrusters operate at full efficiency here — they are S-tier for liftoff. Electric thrusters are not your launch workhorse on Earth unless you are experimenting.

Earth stations teach:

• Frame construction and cable routing
• Atmospheric climb and basic RCS orientation
• First delivery missions that unlock electric thrusters and advanced logic

Recommended instruments: velocity meter, altimeter, radar before long trips — see Sensors tier list. Run Thrust calculator with Earth gravity before hauling mission cargo.

Moon — low gravity, vacuum landing discipline

Earth’s Moon (and moon-like bodies in the roster) pushes vacuum propulsion and RCS-heavy landings. Atmospheric thrusters do nothing in vacuum; electric thrusters carry vertical burns. Community strategy mounts two electric thrusters vertically on center of mass, uses RCS tilt to point, and pulses vertical thrust to translate — similar to historical lunar lander profiles.

Moon differences that matter:

Factor	Earth	Moon (typical)
Gravity	High	Low
Atmosphere	Dense	Thin (atmospheric thrusters work low and slow)
Primary thrust	Atmospheric	Electric + atmospheric low-altitude
Landing style	Aerodynamic + retro	Pulse + RCS
RCS wear	Moderate	High on long approaches

Pack spare RCS blocks or wired maneuvering thrusters for multi-minute approaches. Dampers help touch-down without snapping legs. Use atmospheric thrusters for low-altitude lunar skims — a common surprise covered in the Moon Landing Guide.

Basalt and Solar Storms

Basalt is a post-Moon destination on many crew routes. Patch 1.0.008 reduced Solar Storm strength on the Moon → Basalt transfer so the trip is about 99% safe (a tiny burn chance remains). That matters for:

• The Solar Storm achievement — you can still encounter storms, just less often as an instant route-killer on this hop
• Power planning — keep critical radar / RCS / life-support on independent branches if you chase storm encounters
• Co-op briefings — update friends still flying pre-1.0.008 mental models of “Basalt = guaranteed fry”

Cross-check live balance on Patch Notes after every 1.0.x drop.

Oldara and Fred’s Star (demo finale history)

Oldara appears in the Fred’s Star demo finale added June 6, 2026 — Fred’s failed wormhole experiments, dead water-world biomes, and a descending blue star threaten the whole system. Mission flow uses scanner/tower objectives rather than simple pad delivery. Read Fred’s Star finale before flying there; bring Radar and co-op roles if possible.

Outer-system bodies — Aundara, Baobara, Outcast, Tenebra

Beyond the Moon/Basalt loop sits the outer-system progression chain every save eventually crosses. Treat it as a planning cheat sheet; deep per-planet details live in All Planets & Locations.

• Aundara — a small reddish dot visible from the Moon; sits about 95M m from the Moon after the 1.0.005 distance tweak. Light gravity (~0.3 g), thin but real atmosphere, so atmospheric thrusters still bite for landing. Pair with Solar Panels for free cruise power on the 2-hour transfer.
• Baobara — the ocean planet that finishes the submarine arc; deep trenches including Green Trench. Bring a sealed hull and RCS assist — see Submarine Build. Unlocks the next planet via a space scanner block once all Baobara missions are complete.
• Outcast — distant red-dwarf body tied to the See You Next Week achievement; long Aundara ↔ Outcast leg punishes skimpy batteries. Pack spare RCS, a second Autohemisphere Solar Panel, and radar for the small-body approach.
• Tenebra — the farthest named world (Edge Of The Known achievement); expect heat-resistant frames, redundant cooling, and an abort burn capability. Most pilots unlock Tenebra after most other planets and the Saving The Twins story beat.

If you cannot find a planet, slow your ship and rotate until both radar bearing angles stop drifting in the same direction — community testers confirm the next-destination dot is real but subtle.

Sun, black hole, and sandbox routes

The system map includes a Sun and a black hole behind it — optional exploration, not required for Moonstep progression. Community pilots use trajectory curvature meters and velocity integrators to avoid direct Sun headings (ships heat-break around 330 million meters on straight Sun lines). Treat these as advanced sandbox goals; full release may expand hazards on later planets.

Planet Stations as checkpoints

Stations are more than lore markers:

1. Build zone — assemble or repair ships without returning to Earth.
2. Mission hub — pick deliveries, experiments, and unlock rewards locally.
3. Fast travel anchor — once unlocked, you can launch from there forever.

When planning a route, ask: If I crash halfway, where is the nearest unlocked station? Early players chain Earth → nearby moons → back to Earth for parts. Mid-game players leave specialized hulls parked at stations (atmo-only skimmers vs vacuum tugs) instead of one-ship-for-all.

Gravity and ship design

Higher gravity increases weight for the same mass, lowering TWR unless you add thrust or shed blocks. Low gravity forgives heavy frames but makes fine control harder — small RCS taps overshoot.

Rules of thumb:

• High-gravity worlds — prioritize thrust margin and sturdy dampers; avoid decorative window spam.
• Low-gravity moons — prioritize RCS symmetry and electric vertical thrust; atmospheric parts are dead weight.
• Mixed routes — hybrid ships or station-stored swaps beat single designs.

Always recalc TWR when jumping between worlds; Moon success does not imply outer-planet success.

Atmosphere and thruster selection

Atmospheric density determines whether atmospheric thrusters produce meaningful force. Thick atmospheres favor them for takeoff and skim flight. Vacuum legs require electric or future fuel engines teased for full release.

Cloud layers and weather visuals can block sight lines — radar jumps to S-tier on cloudy planets. Ocean worlds raise questions about surface landing vs station pads; scan mission text and use external cameras when previewed in full release.

Temperature and special hazards

Steam marketing highlights temperature and exotic mission payloads — experimental power sources, heavy submarines, ticking crystals. Planets with extreme temperature may push heat-resistant frames and power cooling in the full game. Demo players already see mission variety that stress-tests thrust and cabling; expect harsher biomes on later planets.

Treat hazard text in missions as map metadata: if a world hosts “unexpected power outages mid-flight,” pack redundant batteries and simplify logic.

Soundtrack and exploration flavor

Each planet ships with a dynamic soundtrack reacting to exploration beats — not a mechanics stat, but a cue that you entered a new biome worth scouting. Use audio shifts as feedback that your ship crossed into different design territory (thicker air, open vacuum, ocean glare).

Building your personal map

Keep a simple player journal (or co-op shared doc):

• Station unlock order
• Gravity/atmosphere notes per stop
• Which hull is parked where
• Mission rewards unlocked at each node

Wiki pages cannot replace your save-specific network, but Updates will add named planet entries as dataminers and explorers publish verified details post-launch.

Route planning checklist

1. Start gravity and atmosphere known?
2. Vertical TWR acceptable on departure world?
3. Vacuum thrust planned for vacuum legs?
4. Radar/altimeter visible to pilot?
5. Nearest backup station identified?
6. Co-op roles assigned — Co-op guide
