NASA International Space Apps Challenge 2026: the plan

Output of /hack-plan, phase by phase. Built from the corpus and the event's public rules; anything marked pending waits for the organizer's challenge statements or the team's approval.

Recon: NASA Space Apps Challenge 2026

14–15 November 2026 · hybrid (in-person and virtual Local Events + the virtual Universal Event) · theme “The Next Frontier!” · run 2026-09-14 · corpus slug nasa-space-apps-2026, prior nasa-space-apps-2025.

Intake assumptions (defaults — replace when the team is known)

Question Assumed
Team 4 people, may grow to 6 (the maximum): two web/full-stack developers, one data or science person, one design/story person
Pitch language English for the project page (required); Spanish or English for a live Local Event pitch
Local Event An in-person LATAM Local Event if one is near; otherwise the Universal Event
Hardware Laptops only
Hours The Local Event’s schedule within 14–15 Nov (up to 48 h)
Required tech At least one NASA data source or resource (expected, as in 2025)
Ideas already in mind None — and none may be worked on before the event (see rules)

Rules that change the harness

Rubric and lens weights

Criterion (stated) Lens Weight Stated / inferred
Impact impact 20% Stated for 2025; carried to 2026 until the Judging & Awards guide appears (2026-11-13)
Creativity originality 20% Same
Validity scientific-validity 20% Same
Relevance challenge-relevance 20% Same
Presentation storytelling-pitch 20% Same

Each criterion is scored 1–5 at every judging level. Equal weights are an assumption: no percentages are published. The organizer’s own advice (2024 guide) is that teams do well on the first four criteria and under-invest in presentation.

Judging funnel

Phase Who Output Team present?
1 Local Event or Universal Event judges Global Nominees (about 1 in 10 projects in the 2024 guide) Depends on the Local Event format
2 NASA and Space Agency Partner subject-matter experts 45 Global Finalists + Honorable Mentions (2025) No — they review the submission (inference)
3 Executive committee of agency leaders 10 Global Awards No (inference)

Implication: two of the three phases most likely judge the submission without the team in the room. The project page, demonstration link and project link are the pitch for the global phases; the live pitch matters only locally.

Prizes and lanes (2025 award definitions)

Award Definition Lens 2025 winner shape Fit for the default team
Best Use of Science Best and most valid use of science / scientific method validity Molecular dashboard on one GeneLab dataset (spacegenes-plus) Medium — needs a science lead
Best Use of Data Makes space data accessible or leverages it uniquely design, originality Exoplanet pipeline with false-positive checks (resonant-exoplanets) High
Best Use of Technology Most innovative use of technology technical depth Personal weather-risk app (skysense) High
Galactic Impact Most potential to improve life on Earth or in the universe impact Debris compliance platform (astro-sweepers) Medium
Best Mission Concept Most plausible concept and design validity, relevance Habitat survival simulator (pureflow) Medium
Most Inspirational Captures our hearts storytelling, impact National satellite broadband concept (photonics-odyssey) Medium
Best Use of Storytelling Communicates open data through storytelling storytelling Illustrated space-weather story (hercode-space) Medium — needs illustration
Global Connection Connects people around the world through technology impact Orbital data-center optimizer (gaia-leo) Low
Art & Technology Combines technical and creative skills design, technical depth Farming game on NASA imagery (zumorroda-x) Medium
Local Impact Greatest potential for local impact impact Andean reforestation for water security (quenaris) High for a LATAM team

Stacking: in 2025 each award went to a different team, so plan for one award per team (inference). Local Awards are separate and do not qualify a team for global judging.

Saturation and past editions

Domain data availability

NASA resources the 2025 winners named on their team pages: POWER API, Earthdata (Giovanni, GES DISC, earthaccess), DONKI space-weather database, GeneLab (OSD-288), MAST archive (Kepler, TESS, JWST, Hubble), Landsat and MODIS vegetation indices (NDVI, EVI, NDMI), FIRMS fire data, LAADS DAAC, the U.S. Drought Monitor, Orbital Debris Program Office tools (Debris Assessment Software, ORDEM), and the NASA Image and Video Library. Account setup and learning these APIs is general preparation, not challenge work.

LATAM public-sector data (via Croma) is only relevant if a 2026 challenge touches public services; not applicable yet.

Patterns: what won at the last edition, and how it differs from other events

Queries: crafterwiki event nasa-space-apps-2026, patterns --event-kind agency-open-data-challenge, patterns --event-kind student-major-league, patterns --event-kind open-source-community, three similar profiles (see 03-angles.md). Corpus state 2026-09-14.

Sample

n = 10 confirmed winners (the 2025 Global Winners), one edition, one event. Mechanism tags are mostly curator inference; organizer- and team-stated claims are labelled in each record. Treat every number below as a prior, not a law.

How this differs from other kinds of event

Signal Agency open data (n=10) Student major league (n=6) Open-source online (n=8)
Physical artifact 0 4 0
Cultural reference hook 0 4 0
Complete submission package (tagged) 1 0 7
Human stakes 5 2 1
Expert data made accessible 4 0 0
Top lens challenge relevance wow factor / technical depth impact / technical depth

Reading: the student-event playbook (hardware on the table, a pop-culture hook, a live “wait, it does that?”) does not transfer. At the agency challenge, winners answered the challenge closely, made expert data usable by a named person or place, and showed real depth — often without AI.

Similar situations

Angle shape Nearest winners (score) What they share
A · one-tap local decision skysense (0.68), quenaris (0.57), spacegenes-plus (0.38) earth observation; expert data for everyone; place specificity
B · stress test with live data resonant-exoplanets (0.64), pureflow (0.47) visible depth; cited evidence; live real-world proof
C · play the stakeholder zumorroda-x (0.79), hercode-space (0.46) familiar thing, new job; human stakes; storytelling lens

Every shape has a 2025 winner as its nearest neighbour: these shapes can win, and judges have seen them. The edge has to come from combination and specificity, not from the shape.

Crowded lanes

Unknown. With a winners-only roster the corpus cannot say how many of 11,500+ submissions built a weather app or a farming game. Curator inference: “personal weather/climate app” is the most obvious reading of Earth-observation challenges, so assume it is common and plan an edge.

Update: two editions (2026-09-14)

The 2024 Global Winners were indexed as a holdout after this file was written (docs/research/holdout-nasa-2024.md). Agency sample now n = 20.

Signal 2025 2024 Total
expert-data-for-everyone 4 8 12
visible-engineering-depth 5 5 10
human-stakes 5 1 6
place-based-specificity 3 2 5
Custom hardware 0 0 0
No AI in the product 5 4 9
LATAM award winners 3 3 6

Reading: accessible expert data and visible depth held; human stakes did not. The angle verdict in 03-angles.md is revised accordingly.

Pre-registered predictions for the 2026 Global Winners

Written 2026-09-14, before 2026 challenges exist. Grade in January 2027 by tagging the 2026 winners with the same taxonomy from NASA’s announcement and team pages. Baseline in brackets is the 2025 value.

# Prediction 2025
P1 At most 1 of 10 winners builds custom hardware 0
P2 At least 4 of 10 winners carry human-stakes or place-based-specificity 5
P3 At least 3 of 10 winners have no AI in the product 5
P4 At least 2 of 10 winning deliverables are a story, game or concept design rather than a conventional software product 3
P5 At least one challenge produces 2 or more Global Winners yes (3)
P6 At least 9 of 10 winner pages name specific NASA datasets and link a demonstration 10
P7 At least 2 of the 3 awards Best Storytelling, Art & Technology and Most Inspirational go to a story, game, concept design or crafted interactive experience rather than a data tool 3 of 3 (2024: 3 of 3)
P8 The Local Impact winner carries both human-stakes and place-based-specificity yes (2024: yes)

P7–P8 were added on 2026-09-14 after the 2024 holdout and before any 2026 challenge exists; P1–P6 are unchanged. P7–P8 test the award-first step proposed in 03-angles.md.

Context prior (not a harness claim): LATAM teams won 3 of 10 awards in 2025.

Problems and angle shapes

Rule-limited phase. Teams may not work on 2026 challenges before 14 November, and the challenges are not public yet. This file holds problem families and structurally different angle shapes keyed to the award lanes — not solutions. On 2026-09-17 map each family to a challenge summary; drop families with no match.

Problem families (≥ 6)

# Person · moment it hurts · consequence Team proximity NASA data
1 A smallholder farmer deciding when to plant or irrigate; a dry spell or heat wave wipes out the season LATAM agriculture context NDVI/EVI (MODIS, Landsat), POWER, drought monitors
2 A water utility or community in an Andean city watching springs dry up as vegetation cover is lost LATAM, direct precedent (quenaris) MODIS/Landsat indices, Earthdata
3 A family or school near a fire-prone area deciding whether to evacuate or close; smoke arrives before warnings Seasonal fires in South America FIRMS, air-quality products
4 A delivery rider, outdoor worker or event organizer planning the day; heat or storms hit mid-shift Urban LATAM gig work POWER, Earthdata weather variables
5 A teacher or student trying to make sense of space science data (exoplanets, space biology, space weather) Education and community events MAST, GeneLab, DONKI
6 An operator or regulator in low Earth orbit facing debris risk or connectivity gaps in remote regions Business-framed challenge; 3 awards in 2025 Orbital Debris Program Office tools, Space-Track
7 A pilot, grid operator or GNSS-dependent farmer affected by a solar storm without understanding it Space-weather challenges recur DONKI

Killed now: any family that needs custom hardware (no 2025 precedent and no hardware assumed), and any “platform for everything” without a named person.

Evidence pass

Angle shapes

A · One-tap local decision

Field
One sentence (template) “For [person] in [place], we turn NASA [dataset] into [one decision], with the evidence.”
Moment (live or on video) A judge enters their own city and date and gets the decision, the dataset and its date, and how sure it is — in under 20 seconds
Human stakes A named local user whose season, shift or water supply depends on the decision
Mechanisms expert-data-for-everyone, place-based-specificity, one-sentence-clarity, cited-evidence-trust
Nearest neighbours skysense (award winner): personal weather decision · quenaris (award winner): one named place and causal chain
How it must differ SkySense’s decision UX plus QUEÑARIS-level place specificity plus an explicit “how sure are we” — neither winner made uncertainty the feature
Lens fit Impact 4 · Creativity 3 (seen before) · Validity 4 if uncertainty is shown · Relevance 5 on Earth-observation challenges · Presentation 4
Must work One real query over one NASA dataset for one region, fast
Cut list Accounts, notifications, chat assistant, many regions

B · Stress test with live data

Field
One sentence (template) “Design or predict [thing], then hit it with today’s NASA [feed] and see whether it holds.”
Moment The latest event from a live NASA feed changes the result on screen: a design fails, a false positive is rejected
Human stakes A crew, operator or scientist about to make a costly decision
Mechanisms live-real-world-proof, visible-engineering-depth, cited-evidence-trust
Nearest neighbours resonant-exoplanets (award winner): false-positive checks · pureflow (award winner): live space-weather stress test
How it must differ The failure is the demo: show it happen and explain it in one visual
Lens fit Impact 3 · Creativity 4 · Validity 5 · Relevance 3 (fits only some challenges) · Presentation 3–4
Must work Live fetch plus a deterministic evaluation, with a cached fallback
Cut list 3D polish, scenario editors

C · Play the stakeholder

Field
One sentence (template) “You are [person]; real NASA data decides what happens to you.”
Moment A judge plays 30 seconds and a real satellite image or data point changes the outcome
Human stakes The character’s livelihood or safety
Mechanisms familiar-thing-new-job, human-stakes, expert-data-for-everyone, place-based-specificity
Nearest neighbours zumorroda-x (award winner): farming game · hercode-space (award winner): children’s story
How it must differ The player’s own place drives the level; otherwise it reads as a repeat of 2025
Lens fit Impact 3 · Creativity 3–4 · Validity 3 · Relevance depends on a story/game challenge · Presentation 5
Must work One playable scene on real data
Cut list More levels, art beyond one scene

Judge panel (Gate 1)

Personas

  1. Local judge (mentor at a LATAM Local Event) — rewards a clear pitch, a working demo, local relevance.
  2. Earth-science SME — rewards correct data use, stated uncertainty, a checkable method.
  3. Heliophysics / space-operations SME — rewards physical plausibility.
  4. Executive committee member — rewards stakes and memorability among 45 finalists.
  5. Science communicator — rewards a page and video that explain it in a minute without the team.

Scores (1–5, equal weights)

Criterion A B C Justification (persona)
Impact 4 3 3 (4) A names a person and a place; B’s stakes are indirect; C’s are fictional
Creativity 3 4 3 (2) A is the obvious reading; B’s live failure is less common; C repeats 2025
Validity 4 5 3 (2) A holds only if uncertainty is shown; B is built around it; C simplifies
Relevance 5 3 3 (1) A fits most Earth-observation challenges; B and C fit fewer
Presentation 4 3.5 5 (5) C tells itself; B needs the failure to be visual
Mean 4.0 3.7 3.4

Seen-before check

All three shapes have a 2025 award winner as nearest neighbour (skysense, quenaris; resonant-exoplanets, pureflow; zumorroda-x, hercode-space). That proves the shapes win, and it means the SMEs have seen them. Crowding among submissions is unknown (winners-only roster).

Biggest objections

Persona Objection Neutralizer
Earth-science SME “Another weather app.” Make trust the feature: show when the data should not be believed
Executive “Why this place?” One named community with a number that matters to it
Communicator “I can’t tell what it does from the page.” First line of the page is the one sentence; video opens on the decision
Local judge “Does it work or is it a mockup?” Real query on stage; recorded fallback disclosed as such

Verdict

Revision after the 2024 holdout (2026-09-14)

The verdict above was tested on the 10 NASA Space Apps 2024 Global Winners, indexed after the hypotheses were written (docs/research/holdout-nasa-2024.md).

Target award What won in both 2024 and 2025 Start from
Local Impact a named person and place (grow-team-io, quenaris) A
Best Storytelling · Art & Technology · Most Inspirational a story site, game, concept design or crafted interactive experience (6 of 6) C
Best Use of Science an overlooked angle on expert data (skyshield-wmpgang, spacegenes-plus) A, with B’s check
Galactic Impact · Global Connection a hard method shown on the page (visible engineering depth, 4 of 4) B-style depth
Best Use of Data · Best Use of Technology · Best Mission Concept no consistent pattern decide on the challenge

Revised verdict

Demo script: local decision with a live validity check

Template for the merged angle. Bracketed parts are filled on 14 November, once the challenge is chosen.

One sentence

“For [person] in [place], we turn NASA [dataset] into [one decision] — and show when not to trust it.”

Repeatability test: a judge should be able to say it to another judge without the words API, model or dashboard.

Stage plan

Global judging variant (the submission wins without you)

Mirror the section order every 2025 winner used on its team page:

  1. Summary — first line is the one sentence; then person, place, decision, and why the data can be trusted.
  2. Project Demonstration — link to a short video that opens on the decision (length and format per the 2026 Project Submission Guide, published 2026-11-13; do not assume).
  3. Project — live site or repository that still works after the event.
  4. Project Details — how it works, the validity check, tools, what is next.
  5. Use of Artificial Intelligence — tool by tool, what each did and what the team built (the 2025 Best Use of Technology winner is a good model).
  6. NASA Data — every dataset, named and linked.
  7. Space Agency Partner & Other Data — everything else, named and linked.

Checklist: English throughout (subtitles for other languages) · at least one NASA resource linked · AI disclosure and watermarks · no NASA branding · all members registered at the same Local Event.

Rehearsal checklist

Architecture: Gate 2 is closed

Status: not approved, by design. Gate 2 needs the team’s approval of a concrete angle, and the event forbids working on challenges before 14 November; the challenge statements arrive on 28 October. This file therefore records only the constraints any demo-path architecture must meet. The actual design is made at the start of the hackathon, after the team approves the angle.

Demo path (shape only)

flowchart LR
  Q[Place + date + question] --> F[Fetch NASA dataset for the region]
  F --> C[(Cached snapshot for the demo region)]
  F --> D[Deterministic decision logic]
  C --> D
  D --> V[Validity check: agreement, staleness, coverage]
  V --> O[Decision + evidence + confidence]

Constraints decided now

  1. Only the demo path gets built. One region, one person, one decision. Everything else is a slide.
  2. No language model in the live decision path. If an LLM is used, it only phrases the explanation, a deterministic answer exists without it, and it is disclosed.
  3. A cached snapshot for the demo region ships with the build; the live fetch is attempted first.
  4. The team’s known stack, chosen in the first 30 minutes of the hackathon — no stack debates.
  5. Evidence travels with the answer: dataset name, date and link are part of the output, not a footnote.
  6. Validity check is a component, not a slide: it must run on the demo query.

Spikes for the first two hours of the hackathon

Spike Question Kill criterion
Data access Can we get the chosen dataset for the demo region in the event network? No data in 60 minutes → switch dataset
Latency Does the query return in under 5 seconds? No → precompute for the region
Validity signal Is there a real way to show when the data is unreliable (cloud cover, gaps, disagreement between sources)? No → reconsider the merged angle

Build plan

Two parts: legitimate preparation until 13 November (no challenge work), and the plan for the hackathon itself.

Part 1 — Preparation (now → 13 November)

When Do Not allowed
This week Register; choose a Local Event (all members the same); read the Participant Terms & Conditions, including any rule on pre-existing code
17 Sep Read challenge summaries; shortlist three that fit the angle shapes; team formation opens — recruit the missing roles Starting any solution
Sep–Oct Skill drills on past data: each member creates an Earthdata login and pulls one dataset listed in 01-recon.md (POWER, MODIS/Landsat indices, FIRMS, DONKI) into a throwaway notebook Building toward a 2026 challenge
Sep–Oct Prepare team tooling: shared drive, AI-use log template, screen-recording setup, a generic submission checklist Designing screens for a challenge
28 Oct Read full challenge statements; pick the challenge; list problems on paper Code, designs or data pipelines for it
2 Nov Join Space Apps Connect; ask Local Lead about schedule, venue network and judging format
13 Nov Read the Project Submission and Judging & Awards guides; update 01-recon.md (rubric, video rules) and this plan

Part 2 — Hackathon (relative hours; fit to the Local Event schedule)

Hour Milestone
H0–H1 Lock the challenge; fill the one sentence; run the judge-panel check again on the real challenge
H1 Gate 2 with the whole team: sentence, moment, script summary approved
H1–H3 Spikes from 05-architecture.md (data access, latency, validity signal)
H3–H14 Core demo path; page skeleton started in parallel
H14–H18 Integration on the demo region; fallback snapshot saved
H18–H24 Sleep in shifts — nobody works more than one shift through the night
H24–H30 Validity check visual; polish only what is on the demo path
H30 Code freeze on the demo path
H30–H32 Rehearsal 1 (timed, network off once); fix
H32–H35 Record the demonstration video; write the page sections
H35–H36 Rehearsal 2; final page read-through by someone who did not build it
≥ 2 h before 23:59 local Submit — then verify the page, links and video play from another device

Roles from hour one

Role (4-person team) Owns
Data lead Dataset access, snapshot, validity signal
App lead Demo path and deployment
Story/design lead One sentence, page, video, visuals, AI disclosure log
Pitch/PM lead Timeline, rehearsals, Local Event pitch, submission checklist

With 5–6 people add a science reviewer (checks every claim on the page against the data) and a video editor.

Bottleneck check

Single point Mitigation
One Earthdata account or API key Every member has their own account before the event
One laptop with the video editor Export drafts to the shared drive every hour after H30
One presenter Second presenter runs rehearsal 2
Live data feed or venue network Cached snapshot + recording, disclosed if used
One person writing the page Page sections assigned by owner at H3

After the event

Run wiki-curate to record planned vs actual: which angle shape was used, what changed at Gate 2, and the outcome at each judging phase. Grade the predictions in 02-patterns.md when the 2026 Global Winners are announced.
