Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade
Radio Science, Volume 60, Issue 7, July 2025.Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 769, April 2025 Part B.The evolution of wind gusts is difficult to observe because gusts are short‐lived phenomena that can originate at higher altitudes. During the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL), novel ground‐based remote‐sensing methodologies were applied to measure wind with Doppler lidars in order to provide the ...

Remote Sensing in Ecology and Conservation, Volume 11, Issue 2, Page 133-155, April 2025.This paper presents an interdisciplinary perspective of the next generation of spaceborne remote sensors applied to wildland fire management. We highlight the potential improvements in fuel characterization at large scale arising from the use of new spaceborne instruments with near‐global, freely‐available data.
