Orbital Sidekick

Orbital Sidekick is a San Francisco-based hyperspectral satellite imaging company founded in 2016 operating a constellation of hyperspectral sensors optimized for infrastructure monitoring, environmental compliance, and resource exploration — providing customers with continuous spectral fingerprinting of pipeline corridors, industrial facilities, mining sites, and ecosystems that identifies material composition, chemical anomalies, and change events invisible to conventional multispectral or RGB cameras.

Orbital Sidekick's satellites carry hyperspectral imagers that capture reflected sunlight across 400+ narrow spectral bands spanning visible through shortwave infrared (SWIR) wavelengths (roughly 400-2500nm). This spectral breadth enables material identification through spectral fingerprinting: hydrocarbons (crude oil, methane, natural gas condensate) have distinctive absorption features in SWIR wavelengths that allow detection of pipeline leaks, tank farm spills, and flaring events from orbit without requiring ground sensors along the entire pipeline route. The company's AURORA constellation, initially deployed as hosted payloads through SpaceX rideshare and Loft Orbital platforms, provides recurring coverage of customer-specified areas of interest.

Pipeline monitoring is Orbital Sidekick's primary commercial market: oil and gas pipeline operators face regulatory requirements for leak detection monitoring across thousands of kilometers of right-of-way, much of it in remote terrain where traditional survey methods require helicopter or ground crew patrols at high cost and low frequency. Orbital Sidekick's spectrally-detected hydrocarbon anomaly mapping provides systematic monitoring at the cadence of satellite revisit (days rather than months), reducing both operational cost and environmental liability from undetected leaks.

Mineral exploration applications exploit hyperspectral geology mapping: SWIR wavelengths detect mineral species (kaolinite, chlorite, epidote, alunite, jarosite) associated with hydrothermal alteration zones that accompany economic mineral deposits. Exploration geologists use Orbital Sidekick data to prioritize ground sampling and drilling programs in large untested areas.

Methane detection leverages SWIR absorption at 1660nm and 2300nm to detect methane plumes from landfills, coal mines, livestock operations, and oil and gas facilities — supporting methane emissions monitoring programs under voluntary corporate sustainability commitments and evolving regulatory requirements. Competitors include GHGSAT (Canada, dedicated methane monitoring), Kuva Space, and Pixxel.
