Accelerated Knowledge Discovery: A Vision for NASA Science
Abstract This paper introduces the sixth paradigm of scientific discovery: accelerated knowledge discovery (AKD). This paradigm is defined by the full integration of artificial intelligence (AI) into the research workflow as a tool augmenting cognitive capabilities of human scientists.

JWST/NIRSpec Reveals the Atmospheric Driver of Saturn's Variable Magnetospheric Rotation Rate
Abstract Past measurements of Saturn's upper atmosphere have allowed only a broad scale view of the temperature and ion density structures within the auroral region. However, Saturn's auroral currents include a planetary period current component that is produced by neutral atmospheric flows.

Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions
Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Abstract During Galileo's closest (“E12”) flyby of Europa, a brief burst of wave activity was recorded by the plasma wave instrumentation, PWS. This was speculatively interpreted by Jia et al. (2018, https://doi.org/10.1038/s41550‐018‐0450‐z) as a 2,100 cm−3 spike in plasma densities from a water plume encounter. While the plasma instrument, PLS, could

The Hubble Space Telescope will employ magnetic torque controllers, which make use of the Earth's magnetic field augmented by four reaction wheels. DC torques are easily allowed for, but variations, orbit by orbit, can result in excessive wheel speeds ...
