A Bibliometric Review of the INCOSE's Model‐Based Systems Engineering Roadmap

Systems Engineering, EarlyView.
ABSTRACT Over the past decade, model‐based systems engineering (MBSE) has gained attention as an approach for managing system complexity, offering a shift from a document‐based to a model‐based approach. The International Council on Systems Engineering (INCOSE) sparked increasing interest when it introduced MBSE and its roadmap as part of its systems ...

Impact of Spatial Scale on Optical Earth Observation‐Derived Seasonal Surface Water Extents

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Landsat‐derived products are the most prominent, publicly available sources of large‐scale surface water extent data. However, few studies have assessed the limitations of spatial scale on such products. Here, we mapped seasonal surface water extents utilizing high‐resolution (4.77 m) PlanetScope Basemap imagery and machine learning.

USU’s GASPACS CubeSat

, 2022
The Get Away Special Passive Attitude Control Satellite (GASPACS) is a 1U CubeSat technology demonstration mission designed to test inflatable structures in space. The project aims to present a possible solution to the limited capacities of spacecraft by providing an inflatable boom that can be packed into a small space and then expanded into something

Efficient and Reliable Solar Panels for Small CubeSat Picosatellites

International Journal of Photoenergy, 2014
CubeSat picosatellites have a limited area of walls for solar cells assembling and the available area has to be effectively shared with other parts, such as planar antennas, optical sensors, camera lens, and access port.

The Dominant Role of the Electron Isotropy Boundary in Controlling Earth's Outer Radiation Belt Electron Lifetimes

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Field‐line curvature scattering (FLCS) is believed to be the primary mechanism forming electron isotropy boundaries (IB) and can rapidly scatter relativistic electrons from the outer radiation belt. However, its direct and quantitative impact on controlling outer belt electron lifetimes has never been directly assessed.

The Deformable Mirror Demonstration Mission (DeMi) CubeSat: optomechanical design validation and laboratory calibration

, 2018
Coronagraphs on future space telescopes will require precise wavefront correction to detect Earth-like exoplanets near their host stars. High-actuator count microelectromechanical system (MEMS) deformable mirrors provide wavefront control with low size ...
