Small spacecraft stack compression
How far can power, thermal, computing, communications, autonomy, and safety cases compress into smaller spacecraft without losing reviewability?[1]
What is being pushed
The practical frontier is not only making spacecraft smaller; it is making small spacecraft evidence-rich enough that a personal or educational path can be reviewed safely.[1]
Why it is hard
Small spacecraft trade mass against power, thermal stability, communications margin, reliability, deployer rules, mission operations, and disposal constraints.
Key parameters
Relation candidates
| From | To | Type | Confidence |
|---|---|---|---|
| small spacecraft bus | reviewable personal path | capability_compression | medium |
| deorbit/disposal plan | public claim boundary | safety_gate | high |
Evidence signals
- NASA's state-of-the-art report provides a structured way to track small spacecraft subsystems and maturity.[1]
No RF settings, antenna construction, launch operations, propulsion methods, or authorization conclusions belong on this page.

Exoplanet biosignature evidence
Can future telescopes distinguish possible life signatures from atmospheric chemistry, stellar noise, and instrument ambiguity?[2]
What is being pushed
The scientific frontier is to turn distant light into cautious evidence about atmosphere, planet context, and possible biological signatures.[2]
Why it is hard
A biosignature candidate can have non-biological explanations, and atmospheric observations depend on telescope sensitivity, stellar behavior, chemistry models, and repeated confirmation.
Key parameters
Relation candidates
| From | To | Type | Confidence |
|---|---|---|---|
| atmospheric spectrum | biosignature candidate | evidence_context | medium |
| false-positive pathway | public claim boundary | caution_gate | high |
Evidence signals
- NASA frames the search for life around careful interpretation of exoplanet signals and biosignature evidence.[2]
Do not write discovery claims, certainty language, or story lore as if a biosignature has been confirmed.

Dark universe measurement frontier
What measurements can make dark matter, dark energy, black holes, and the early universe less invisible?[3]
What is being pushed
The frontier is to connect gravitational waves, high-energy observations, cosmic expansion, and precision surveys into a clearer physics picture.[3]
Why it is hard
The core objects are not directly visible in everyday terms. The evidence comes through indirect measurement, model comparison, and long-baseline observation.
Key parameters
Relation candidates
| From | To | Type | Confidence |
|---|---|---|---|
| survey depth | model constraint | measurement_context | medium |
| gravitational-wave event | black-hole population | messenger_evidence | medium |
Evidence signals
- NASA's Physics of the Cosmos program centers these measurement questions as active astrophysics frontiers.[3]
Keep speculative story ideas separate from measured astrophysics and label inference strength clearly.
