User description

Summary

  • Implemented a physics-based thermospheric air density ($\rho$) and satellite orbital decay calculation engine in backend/services/weather_service.py.
  • Added the /api/v1/weather/drag-estimator GET endpoint in backend/api/v1/endpoints/weather.py supporting customizable altitude ($h$), mass ($m$), area ($A$), drag coefficient ($C_d$), and $K_p$ index parameters.
  • Created the interactive DragEstimatorWidget.tsx frontend component with live slider controls and color-coded drag risk severity badges (NOMINAL, ELEVATED, HIGH, CRITICAL).
  • Connected SpaceWeather.tsx to live backend telemetry APIs (/api/v1/weather/status).
  • Fixed a minor endpoint decorator bug in backend/api/v1/endpoints/catalog.py ensuring clean server startup.

CodeAnt-AI Description

Add live space-weather monitoring and satellite drag-risk estimates

What Changed

  • Space Weather now loads live NASA telemetry for geomagnetic activity, CMEs, solar flares, storms, and radiation events, with fallback values when the service is unavailable
  • Added an interactive estimator for satellite altitude loss, atmospheric density, orbital speed, drag risk, and estimated orbital lifetime
  • Users can adjust altitude, mass, cross-sectional area, and drag coefficient and receive updated results and risk guidance
  • Expanded the dashboard with CME conditions, solar activity trends, telemetry source, and satellite operations impact indicators
  • Restored catalog object and space-object detail routes for reliable catalog access

Impact

✅ Live solar and geomagnetic activity visibility
✅ Satellite-specific orbital decay estimates
✅ Clearer drag-risk and orbit-maintenance guidance

Review Change Stack

📝 Walkthrough

Walkthrough

The PR adds a catalog-object route, a backend atmospheric-drag calculation and API, an interactive drag estimator, and live space-weather telemetry rendering.

Changes

Space Weather Telemetry and Drag Estimation

Layer / File(s) Summary
Drag estimator backend
backend/api/v1/endpoints/weather.py, backend/services/weather_service.py
The API validates orbital inputs, resolves a Kp value, and returns atmospheric-drag metrics. The service calculates density, drag, orbital decay, lifetime, and risk.
Interactive drag estimator
frontend/src/components/space-weather/DragEstimatorWidget.tsx
The widget provides orbital controls, backend retrieval, local fallback calculations, risk classification, metric cards, and advisories.
Live telemetry dashboard
frontend/src/pages/SpaceWeather.tsx
The page fetches live weather status, retains fallback metrics on failure, embeds the drag estimator, and renders updated solar, CME, and satellite-impact sections.

Catalog Object Retrieval

Layer / File(s) Summary
Individual catalog object route
backend/api/v1/endpoints/catalog.py
The catalog API adds a GET route for retrieving one object by catalog number.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to e5dac

The PR adds live space-weather telemetry and an interactive drag estimator, but deployed users may receive fallback/default data because the frontend targets a local backend address, while several displayed values can misrepresent live conditions and slider interaction can generate excessive backend requests. These concrete integration, accuracy, and availability risks should be addressed before merging.

Explanation

The PR implements the core requirements in [#206], including live telemetry, drag calculations, the estimator endpoint, and interactive controls. Compliance is incomplete because the issue requires a SEVERE risk level while the frontend uses CRITICAL, and integration with /api/v1/weather/all is not confirmed.

Suggestion: When kp_index is omitted, this endpoint synchronously calls get_current_status(), which performs four separate DONKI fetches. The widget invokes this endpoint on every slider movement, so a single user interaction sequence generates repeated external API calls, added latency, and possible DONKI rate limiting. Reuse cached weather status or accept the Kp value already fetched by the page. [performance]

Severity Level: Major ⚠️
- ⚠️ Slider interactions incur four external API calls each.
- ⚠️ Estimator latency depends on NASA DONKI responsiveness.

Suggestion: The fallback fixes Kp at 3.0 and therefore removes the live geomagnetic-storm density scaling used by the backend. During backend/API failure, a storm can be reported as nominal with an understated decay rate and lifetime instead of matching the normal estimator behavior. Preserve the current Kp value when calculating locally or avoid presenting the fallback as live weather-aware output. [api mismatch]

Severity Level: Major ⚠️
- ⚠️ Fallback density ignores live geomagnetic conditions.
- ⚠️ Storm-time decay and lifetime are understated.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win

Cache the live Kp lookup on the drag-estimator path.

get_current_status() performs six upstream NASA DONKI requests (GST, FLR, CME, SEP, RBE) with a 20 s client timeout each, and it does not cache. kp_index is optional, and DragEstimatorWidget.tsx never sends it, so every slider change triggers this full upstream fan-out. Slider interaction produces request bursts, so response latency can reach tens of seconds and the sync-endpoint threadpool can saturate.

Add a short-lived cache for the current status, or fetch only the geomagnetic-storm feed for the Kp default.

♻️ Example: fetch only the Kp source for the default
     if kp_index is None:
-        status = weather_service.get_current_status()
-        kp_index = float(status.get("kp_index", 3.0))
+        gst = weather_service.fetch_geomagnetic_storms(days_back=3)
+        kp_index = float(gst[-1].get("kp_index") or 3.0) if gst else 3.0

The estimator uses fallback values, and the dashboard retains default metrics. Use VITE_API_URL ?? "/api/v1" or a relative /api/v1 path in both files.

Replace the hardcoded 127.0.0.1:8000 base in the fetch request within
DragEstimatorWidget.tsx with the shared VITE_API_URL ?? "/api/v1" configuration.
Apply the same URL-base change to the request in SpaceWeather.tsx so both API
calls use the Vite proxy or configured backend.

Debounce the effect and discard stale responses.

The effect refetches on every slider step. The altitude slider has step="10" across 200–1000, so one drag can start dozens of requests. Each request makes the backend call get_current_status(), which fans out to the NASA DONKI API. Responses can also resolve out of order, so the displayed metrics can belong to an earlier parameter set.

Debounce the input and abort superseded requests.

♻️ Proposed fix
   useEffect(() => {
-    fetchEstimates();
+    const controller = new AbortController();
+    const timer = setTimeout(() => {
+      fetchEstimates(controller.signal);
+    }, 250);
+    return () => {
+      clearTimeout(timer);
+      controller.abort();
+    };
   }, [altitude, mass, area, dragCoef]);

Pass the signal into the fetch call and ignore AbortError in the catch block, so an aborted request does not trigger the local fallback.

-  const fetchEstimates = async () => {
+  const fetchEstimates = async (signal?: AbortSignal) => {
     setLoading(true);
     try {
       ...
-      const res = await fetch(`.../drag-estimator?${query}`);
+      const res = await fetch(`.../drag-estimator?${query}`, { signal });
       ...
     } catch (e) {
+      if (e instanceof DOMException && e.name === "AbortError") return;
       console.warn("Backend API unavailable, using local calculation fallback:", e);
     }

95 - 97, Update the useEffect that calls fetchEstimates to debounce changes to
altitude, mass, area, and dragCoef, abort the previous request when inputs
change or the effect unmounts, and pass the AbortSignal through the underlying
fetch call. Ignore AbortError in the catch path so superseded requests cannot
update metrics or trigger the fallback; retain existing handling for other
errors.

Correct the model attribution.

The text states the calculator is "powered by NRLMSISE / Jacchia density models". The implementation uses a single exponential density model with a linear Kp scale factor, in both the backend and this local fallback. The claim overstates the model fidelity to operators who read the panel.

Describe it as an exponential thermospheric density approximation.

Associate each label with its slider.

Each <label> has no htmlFor, and each <input type="range"> has no id. Screen readers announce the sliders without a name, so keyboard and screen-reader users cannot identify which value they change.

Add matching id and htmlFor values, or add aria-label to each input.

Replace the hardcoded values in the live sections, or label them as sample data.

The page header states "Live Space Weather Intelligence", but the flare trend bars, the peak flare class M1.2, the CME velocity ~650 km/s, the propagation vector, and the +15% Density Boost are static literals. weatherStatus already carries live flare and CME counts, and status.events in the backend response carries the CME speeds and flare classes.

Operators cannot distinguish these values from live telemetry. Bind them to the fetched events payload, or mark the section as illustrative.

weatherStatus data, using appropriate fallbacks when unavailable; alternatively
label the entire section as illustrative sample data. Update the relevant JSX
near the trend visualization and associated metric sections.
