Major changes are expected in the space environment due to imminent launch of NewSpace (sometimes Space 2.0) systems, particularly large low Earth orbit (LEO) constellations that will change operations environment. This new activity could overwhelm current flight safety processes. However, there many encouraging signs government, industry, and community acting address these issues although additional steps remain. These efforts described, some remain be explored discussed.
We sampled stream physical habitat, water temperature, and fish macroinvertebrate communities atmultiple paired watersheds before after BMP installation from 1993 to 1999 examine the responses ofstream quality watershed-scale implementation. Our results clearly demonstrated that watershed-scaleBMP significantly (p < 0.10) improved habitat quality, bank stability, instream cover forfish, catch of cool- coldwater fishes, all fishes. Stream benthic communityand temperature showed consistent...
Abstract Existing DOD and NASA satellite breakup models are based on a key laboratory test, the 1992 Satellite Orbital debris Characterization Impact Test (SOCIT), which has supported many applications matched on-orbit events involving older designs reasonably well over years. To update improve these models, Debris Program Office, in collaboration with Air Force Space Missile Systems Center, The Aerospace Corporation, University of Florida, conducted hypervelocity impact test using...
Satellites have limited awareness of nearby objects that might pose a collision hazard. Small, relatively inexpensive onboard optical local area sensors been proposed as means providing additional awareness. However, such often performance. Proposed are methods to increase the Local Area Awareness provided by classical and novel image processing techniques. The sensor platform is defined, for our purposes, sphere radius 500 km surrounding platform, or observing satellite. This analysis...
