Maps caller-supplied Kp and Dst indices to geomagnetic storm severity bands (G0–G5) and combines them with geomagnetic latitude and infrastructure class to assess impact risk.

Analytically propagates two Cartesian states with constant velocity to compute time of closest approach and determine whether the miss distance falls within the combined hard-body radii of the two objects.

Validates observed weather conditions against caller-supplied launch safety limits and returns every failed rule

Propagates a circular two-body orbit from orbital elements and samples when a satellite is visible above the horizon from a specified ground station location.

Computes a bounded dark-fleet suspicion score for vessel tracks by combining AIS gap duration, unmatched satellite detections, night-observation fraction, and position discrepancy into a single normalized metric.

Estimates crop yield by computing mean NDVI and an OLS daily NDVI trend from time-series observations, then applying a caller-supplied linear model (intercept + mean_coefficient×mean_NDVI + trend_coefficient×daily_trend).

Computes a methane emission flux proxy and optional kg/h estimate from caller-supplied satellite pixel enhancement data, wind speed, plume orientation, and a mass conversion factor.

Labels four-neighbor connected components in a 2-D numeric grid above a caller-defined threshold, returning area, bounding box, peak, and mean value for each component.

Estimates altitude loss and time-to-reentry for a circular orbit using a simplified drag model with caller-supplied atmospheric density and ballistic coefficient

Fits OLS regression to VIIRS/DMSP night-light radiance observations over time, converts the slope to an annual radiance change rate, and applies a caller-supplied economic elasticity to estimate an economic index change.
