Geodetic imaging data from Interferometric Synthetic Aperture Radar (InSAR) are used to measure crustal deformation related to tectonic motions and displacements on earthquake faults. NASA's UAVSAR project and related efforts are creating large catalogs of data products. The user base of these data products is also growing, introducing the need for downstream tools to support computationally expensive...
Honeybee Robotics Spacecraft Mechanisms Corporation has developed a Control Moment Gyroscope product suitable for small spacecraft. Each individual CMG exhibits a nominal angular momentum of 56 mNm-s with a peak of 86 mNm-s, and corresponding output torques of 112 mNm and 172 mNm respectively. Each unit measures 48 × 48 × 91 mm and weighs 600 grams. The control electronics are capable of driving 4...
KySat-2 is a 1U CubeSat launched on the NASA ELaNa IV mission on November 19, 2013. The Command & Data Handling (C&DH) architecture for KySat-2 leverages aspects of the Space Plug-and Play Avionics (SPA) standard developed by the Air Force Research Laboratory (AFRL) and adapts it to the constraints of the CubeSat form factor. The design eases interfacing commercial-off-the-shelf (COTS) and...
The optical vortex coronagraph (OVC) has great potential both for carrying out high-contrast exoplanet searches around nearby stars, and for reducing the size of the space telescopes needed for exoplanet imaging and spectral characterization missions. This is because using a coronagraphic mask to modify the phase of a focal-plane stellar point spread function, instead of its intensity, leaves transmissions...
What would happen if archaeology and aerospace joined forces to test and develop new technology? Not only would it be the basis for an epic movie, there is considerable need in emerging fields of archaeology, like cultural heritage diagnostics, where a fruitful partnership could be forged. Both cultural heritage diagnostics and engineering groups share needs for multi-dimensional and multi-spectral...
