Watchlist

Early-stage players we’re tracking — real enough to watch, too early to catalogue. Tech demos, first hops, filed constellations without an orbital track record yet. Each one joins the live catalogs the moment it clears the bar.

How something gets off the watchlist. The live catalogs (Constellations, Launch providers) track things that are actually flying or have a concrete deployment. The watchlist is everything one step before that.

For a filed constellation, that last step is automatic — the moment CelesTrak reports live satellites matching it, the entry drops off the watchlist and appears in Constellations on its own.

Constellations — filed, not yet flying

E-Spacefounded by Greg Wyler · France
Filed — 3 demo sats

A debris-resistant LEO network pitched at up to 300,000 satellites, filed via Rwanda — sustainability as the core differentiator.

Latest
May 2022 — 3 demonstration satellites launched; nothing operational since.
Next
No firm deployment date — “launching soon” per the founder.

Filed — ITU deadline at risk

A planned 600-satellite Ka-band “Outernet” for secure enterprise and government data, laser-meshed in LEO.

Latest
A $2.4B build contract with Terran Orbital (2023); an Outernet demo mission targeted for 2026.
Next
ITU rules required 144 satellites in orbit by June 2026 (unmet), with 144 more due by September or its spectrum priority lapses.

Filed — pre-hardware

A 791-satellite MEO/HEO “edge-computing” network, opening with a 32-satellite first phase (8 HEO + 24 MEO).

Latest
$135M raised (Series A led by Playground Global); UK service licence (2023). No satellites launched yet.
Next
Closing a Series B to finish payload design; service targeted 2026 (slipping).

Launch vehicles — pre-orbital & R&D

Orbital — maiden failed

Australia’s first home-built orbital rocket — Eris, a small-lift vehicle using hybrid propulsion.

Latest
29 Jul 2025 — Eris TestFlight 1 failed ~14 seconds after liftoff. Australia’s first orbital launch attempt.
Next
TestFlight 2 targeted late 2026; a suborbital hypersonic test may come sooner.

Reusable — suborbital hop

The automaker’s experimental reusable-rocket program — its first move into launch.

Latest
17 Jun 2025 — a 271 m hop-and-land test. First reusable-rocket test flight by a Japanese company.

JAXA RV-XJAXA · Japan
Reusable first-stage prototype

An experimental reusable-booster demonstrator; feeds the JAXA–France–Germany CALLISTO program.

Latest
11 Jul 2026 — first flight, an 11 m hop.
Next
Higher-altitude hop campaign → CALLISTO demonstrator.

JAXA already appears in Launch providers (H3, Epsilon); RV-X is R&D, not an operational vehicle.

Satellite platforms & other

Sat platform — demo 2027

A reusable, returnable satellite bus (Delphi, ~200 kg, ~25% payload) — a platform company, not a constellation operator.

Latest
Mar 2026 — $10M seed on top of a $4M pre-seed (Jun 2025); demo payload sold out.
Next
Delphi demo flight targeted Q1 2027.

Scope.The watchlist is deliberately small and hand-picked. Some pre-launch names already meet the bar for the live catalogs and live there instead — Reflect Orbital and Open Cosmos (concrete constellations, in Constellations), Skyroot (a company-level launch provider). This page is for the ones a step earlier than that.

How I count this

A hand-picked list of early-stage space players — filed constellations, pre-orbital / R&D rockets, and new satellite platforms — that are real enough to track but too early to catalogue as a live operator or launch provider. Each entry joins the live catalogs the moment it clears the bar.

  • Definition

    An entry is on the watchlist if it is an announcement, filing, or tech demo with no established flying operation and no concrete near-term deployment. Three kinds: a filed constellation (a spectrum filing / stated plan, no active satellites yet); a pre-orbital or R&D rocket effort (a hop test, a reusable-booster prototype, a failed maiden flight); and an early satellite-platform or other company that fits neither the operator nor the launch-provider catalog.

  • Source

    Entirely editorial and hand-curated in src/lib/watchlist-catalog.ts. Every entry carries a primary source link; the “latest”, “next” and funding figures are the companies’ own stated numbers, summarised — not independent estimates. The only live input is the CelesTrak active count for a filed constellation, used to detect when it joins the catalog (see below).

  • Joining the catalogs

    A filed-constellation entry is also held in the operator catalog and hidden from the Constellations directory while its active satellite count is zero. The moment CelesTrak reports satellites matching it, its count rises above zero and it moves to Constellations automatically — dropping off the watchlist in the same step. The display location is decided live by the data; the catalog entry never changes. Rocket and platform entries join the catalogs by editorial judgement (an orbital flight, a concrete constellation) into Launch providers or Constellations.

  • Includes

    Companies and programs with public, sourceable activity but no orbital track record yet, deliberately kept off the live catalogs so those stay a record of what is actually flying or concretely deploying.

  • Excludes

    Anything already flying or concretely deploying (that lives in Constellations or Launch providers), and speculative efforts with no sourceable activity. Some pre-launch names that do clear the bar — Reflect Orbital and Open Cosmos (concrete constellations), Skyroot (a company-level launch provider) — sit in the live catalogs, not here.

  • Limitations

    The list is intentionally small and selective, not exhaustive — it reflects editorial judgement about who is worth watching, and dates / figures can lag fast-moving early-stage companies. The automatic move to Constellations only fires if a filed constellation’s eventual satellite names match its pre-registered pattern; the first launch may need a one-time pattern tweak if the real object names differ.
