What you get

Questions this dataset answers

  • When is the next Starlink launch and from which pad?
  • What orbital launches are scheduled this week?
  • Which upcoming launches are 'go for launch' vs TBD?
  • Did the most recent Electron launch succeed?

Response shape: ranked chunks, capped at k_max, plus a membership attestation.

About this dataset

Orbital launch schedule corpus for agents: upcoming launches for the next 14 days (rocket, mission name, provider — SpaceX, Rocket Lab, ULA, ISRO, CASC and others — pad/location, NET time, go/slip status) plus recently-completed launches with outcomes. Built from the Launch Library 2 community API. Launch times slip constantly and statuses update in near-real-time; republish is event-driven on any NET or status change, and every published corpus root is anchored on-chain via AnchorRegistry, so recency is independently verifiable.

How to buy a query

Ask 'when is the next SpaceX/Starlink launch', 'what launches this week', or 'which launches are at risk (go for launch vs TBD)' for the schedule; ask 'did the recent Electron/Falcon launch succeed' for outcomes. NET times update whenever a launch slips.

Freshness

Update cadence
Continuous refresh; republished whenever a launch NET time or status changes (seller-claimed)
Cadence note
Cadence is seller-stated, not measured; republishing is content-gated, so no new version does not mean the pipeline is dead.

FAQ

Do I need an account?

No. Open a prepaid session, fund it, sign the receipt, and query. The listing page never asks for a login.

What do I receive?

Ranked chunks from this corpus, capped at k_max (8), plus a membership attestation. Document bytes are never listed here.

How do I verify freshness?

Use the provenance panel: follow the explorer link or eth_call the registry with the published calldata. Do not take this page as proof.

What is a chunk?

A chunk is a retrieved passage from the corpus — not a full document. Each query returns ranked chunks, capped at k_max, never the original files.

What is the historical coverage?

This listing covers 2026-09-01/2026-09-01. Version history below shows each published snapshot.

Are there rate limits?

Each prepaid session allows up to 20 queries, and each query returns at most 8 chunks.

Can I get a refund?

Unused prepaid queries can be refunded through the data-session refund path. Completed queries are not reversed.
