Opening Insights Microsatellites are redefining what’s possible in high-resolution Earth Observation (EO). Once the exclusive domain of large spacecraft, submeter imaging and hyperspectral data collection are now being delivered by compact, power-efficient platforms. These next-generation systems combine visible and near-infrared (VNIR and NIR) multispectral sensors with new optical architectures—bringing advanced imaging capabilities to a broader […]
Opening Insights Accurate surface reflectance data is essential for Earth Observation (EO) applications ranging from vegetation health monitoring to land use classification and hydrological modeling. However, atmospheric interference — including aerosols, water vapor, and variable solar angles — distorts the radiance captured by spaceborne sensors. This distortion can significantly degrade the scientific utility of raw […]
Opening Insights As nanosatellite and CubeSat missions grow more complex and ambitious, the demand for scalable, flexible satellite platforms has never been greater. From deep-space biological science to lunar surface monitoring and interplanetary maneuvers, nanosatellites are now performing missions once reserved for full-scale spacecraft. These advancements require architectures that can evolve with the mission — […]
Opening Insights Cloud detection remains a fundamental challenge in satellite-based Earth Observation (EO). With up to two-thirds of the Earth’s surface covered in clouds at any time, a significant portion of remote sensing imagery (RSI) becomes contaminated, reducing its utility and increasing data transmission loads. Traditionally, cloud coverage estimation has relied on thresholding, time-differentiation, and […]
Opening Insights Preparing a payload or small satellite for launch requires a precise, multi-phase process to mitigate risk and ensure mission readiness. Across the space industry, facilities are designed to support a spectrum of payloads from compact CubeSats to larger spacecraft requiring 5-meter fairings. These facilities manage the full range of pre-launch ground operations, including […]
Opening Insights Engineering cameras have become an indispensable component in modern space missions, serving as critical instruments for visual feedback. These systems provide invaluable support in environments where real-time human intervention is limited or absent. In the harsh conditions of space, where communication delays can hinder timely decision-making, engineering cameras supplement traditional telemetry with visual […]
Opening Insights The growing presence of resident space objects (RSOs), including active satellites and orbital debris, poses increasing challenges for space situational awareness (SSA). Traditionally, ground-based radar and optical methods have been the primary means of tracking space debris. These methods are constrained by atmospheric conditions, lighting variations, and the limitations of ground-based observatories. As […]
