Why this is a PRD. The day NASA announces the Artemis III crew (2026-06-09), orrery's
static/data/missions/andstatic/data/fleet/contain only 5 forward-looking missions and 5 forward-looking fleet entries. Meanwhile, the architecture has reset hard since mid-2025: Gateway cancelled, Artemis III demoted to a LEO HLS-rendezvous demo, Mars Sample Return cancelled, VIPER revived on Blue Moon Mk1, China's crewed lunar program is hardware-validated for a 2030 landing, Tianwen-2 reaches Kamoʻoalewa today, and India / UAE / Korea / Brazil are all standing up flagship programs. Orrery's "what's planned next" surface is several quarters behind the world. This PRD locks the curated content additions for v0.8 so the implementation slices can start cleanly.
What
24 forward-looking missions + ~37 fleet entries + ~6 updates to existing entries, landing across 4 program-family PRs in v0.8. Curated for big future programs · novel approaches · welcoming newcomers rather than full enumeration. Source-of-truth research backlog lives in docs/research/forward-roadmap-2026-06-09.md (compiled from 5 parallel agency-scope research passes on 2026-06-09).
Out of the ~100 candidate entries in the research doc, the cut to 24 missions + 37 fleet is the minimum that:
- represents every major space-faring program (NASA, US commercial, CNSA, Roscosmos, ESA, JAXA, ISRO, UAE, KARI, AEB) with at least one flagship forward-looking entry,
- shows the architectural pivots (Gateway → surface base; Artemis III demoted; MSR cancelled; ROSS phasing; ILRS multinational expansion),
- foregrounds novel approaches (nuclear-electric SR-1 Freedom, Titan rotorcraft Dragonfly, Toyota/JAXA pressurised Lunar Cruiser, ISRU on Chang'e-8, asteroid-belt tour on MBR Explorer, Comet Interceptor's pristine-target ambush),
- welcomes newcomers (India private launch via Skyroot Vikram-1, Brazil's first orbital VLM-1, UAE asteroid belt + Rashid Rover 2, Korea's KSLV-III + lunar program, first Hong Kong + Pakistani astronauts on Tiangong, Vast's first independent commercial station).

Slice order
Slice 0 (foundation) — `surface-base` category wiring (schema + fleet index + /fleet UI filter + i18n label keys for en-US)
Slice 1 (architecture resets PR) —
· update artemis3 entry → demoted to LEO HLS-rendezvous demo
· add missions: artemis4 · artemis5 · lunar-surface-base-buildup · sr1-freedom
· add fleet: sls-block-1b · starship-hls · blue-moon-mk2 · sr1-freedom-asset · nasa-lunar-surface-base · lunar-reactor-1
· update fleet: new-glenn (LC-36 incident note) · htv-x (PLANNED → ACTIVE) · starship (cross-link to HLS variant)
· mark Mars Sample Return + Lunar Gateway HALO / I-Hab as cancelled / redirected (grep first to see what's there)
Slice 2 (China program block PR) —

· update fleet: tiangong (timeline events for 4th/5th/6th modules)
Slice 3 (newcomers + novel approaches PR) —

· add fleet: orel · angara-a5 (family entry: A5 / A5M / A5P) · ross · vostochny-1a
· (Luna 26 / 27 / 28 + Soyuz-5 + Venera-D + Yenisei optional follow-ups if Marko wants Russia coverage broader than ROSS)Recommended PR order: Slice 0 → 1 → 2 → 3 → 4. Slice 0 unblocks the new category; Slice 1 unblocks all cross-references to the architecture pivots; Slices 2–4 are independent program-family adds.
Time-box note: each program-family slice is one PR + one rebase pass + one preflight cycle. Estimate ~1 day each given the editorial care needed for credit strings, link curation, i18n key drops. The full v0.8 content track = ~5 working days of slice work plus this prep doc + i18n catch-up.
Done definition
Per-slice (1 / 2 / 3 / 4)
- All new mission and fleet entries land as proper JSON under
static/data/missions/{body}/{id}.jsonandstatic/data/fleet/{category}/{id}.json - Every entry has:
id,name,agency,country,status,first_flight(null if not yet flown),best_known_for,credit(1–2 sentences, sourced), at least 3links(Wikipedia / official program / supporting trade press),linked_missionscross-refs where applicable static/data/missions/index.json+static/data/fleet/index.jsonupdatednpm run validate-datagreen (schemas pass, no orphan refs, all cross-link IDs resolve)- en-US strings authored for every user-visible field; other 13 locales accept TODO placeholder or empty-loader-fallback per PRD-007 contract
npm run preflightgreen (typecheck + lint + test + validate-data + build)- Per-entry image/provenance work deferred — these can ship with
creditplaceholders and image-pipeline catch-up in a follow-up wave (don't block content adds on imagery)
v0.8 release acceptance bar
- All 4 slice PRs merged
docs/research/forward-roadmap-2026-06-09.mdkept as the source-of-truth research backlog (don't delete)- This PRD's status moves from "Draft (prep for v0.8)" to "Accepted (v0.8)"
/missionsand/fleetroutes both surface the new entries with working filter chips (surface-base filter chip live)- ≥ 1 entry per agency in {NASA, SpaceX, Blue Origin, CNSA, Roscosmos, ESA, JAXA, ISRO, UAE, KARI, AEB} is represented on the page
Out of scope (v0.8)
- The remaining ~75 entries enumerated in
docs/research/forward-roadmap-2026-06-09.md(CLPS deliveries, full Russia launcher family, ESA observatories beyond Comet Interceptor, all commercial LEO stations, 2026 launcher debut wave). These are deferred to v0.9+ with the research doc as the backlog. - Image curation / image-vision scoring for the new entries — landed via the existing Image Pipeline v2 cycle after content adds, not gated on this PRD.
- Full surface-base 3D rendering on
/moonand future/marssurface routes — separate scope (PRD-009 / PRD-006 extension), foreshadowed by this PRD's data but not implemented here. - Cross-link from
/sciencearticles to the new fleet entries — separate editorial wave under PRD-008. - Locale propagation to non-en-US for the new strings — picks up via the standard translation pipeline (Wave-23 or its successor), not blocked on per-slice merges.
- Roadmap revisions: this PRD's date stamp is 2026-06-09. Anything that shifts before the v0.8 cut (e.g., a confirmed Artemis III crew name announced today, a Tianwen-2 sample-cache event, an Artemis IV HLS provider decision) lands as an in-slice edit, not a separate PRD bump.
Risks
- Date drift. The research dates were accurate at compile time but most are moving targets. Recommend recheck of every "NET 2026 / 2027" date at slice-start time; flag any that have slipped > 6 months in the entry's
creditfield rather than silently shipping an obsolete date. - Newcomer entries with thin English-language sourcing. Vikram-1, VLM-1, Korean Lunar Lander, MBR Explorer's lander sub-element all have thinner public-source coverage than the NASA / SpaceX side. Per AGENTS.md / project memory ("Orrery celebrates global space programs, not just NASA"), the editorial bar is the same — accept that the
creditstrings may need to lean on agency press releases in source language + machine translation rather than Wikipedia. - Architecture re-resets between PRD draft and v0.8 cut. NASA's Feb 2026 reset is unlikely to be the last. If a major pivot lands during slice work (e.g., Artemis IV HLS provider firmed up, ROSS dependent on funded NEM hardware), the affected slice's entries get edited in-flight, not deferred.
- Surface-base category cold-start. It's the first new fleet category since v0.6's launcher / launch-site separation. Schema + filter UI + i18n key drops + ADR-002 pointer all need to be coherent before slice 1 references it. Slice 0 is the explicit guard against this.
surface-base↔stationambiguity for ILRS. ILRS phase-1 is robotic-precursor (basically a fleet of landers); phase-2 is multi-module habitat. Entry name + description must be clear it's a program, not an attempt to model the final base as the v0.8 entity. Same caveat applies to NASA Lunar Surface Base.
Source-of-truth backlog
Full per-agency research (citations + confidence per entry): docs/research/forward-roadmap-2026-06-09.md. Compiled 2026-06-09 from 5 parallel research passes. Use as the slice-time reference for entry copy (best_known_for, credit, links); do not re-derive content from training-data memory at slice time, since these missions are too current for cached knowledge.
