SUDA: A SUrface Dust Analyser for compositional mapping of the Galilean moon Europa

Sascha Kempf

(CU/LASP)

The Surface Dust Analyser (SUDA) is a dust impact mass spectrometer onboard the Europa Clipper mission for investigating the surface composition of the Galilean moon Europa. The instrument is a Time-of-Flight (TOF) impact mass spectrometer derived …

Estimating the optical depth of Saturn’s main rings using the Cassini Langmuir Probe

Georgios Xystouris

(Lancaster University)

A Langmuir Probe (LP) measures currents from incident charged particles as a function of the applied bias voltage. While onboard a spacecraft the particles are either originated from the surrounding plasma, or emitted (e.g. through photoemission) …

Calibrating the Universe with a CANDLE

Susana Deustua

(NIST)

To obtain the precision necessary to meaningfully test dark energy models, or predict the habitability of exoplanets, modern astrophysical experiments have stringent requirements on the control of systematic uncertainties. Dark energy probes that rely on optical …

Study of Atmospheric Ion Escape From Exoplanet TOI-700 d: Venus Analogs

Tomoaki Nishioka

(LASP/University of Tokyo)

The recent discovery of Earth-sized planets in the habitable zones (HZ) of cool stars (M dwarfs) has focused attention on whether liquid water and life exist on these planets. These planets are exposed to stronger X-ray …

Recent spectroscopic observations of stellar flares and possible stellar mass ejections

Yuta Notsu

(LASP)

Flares are frequent energetic explosions in the stellar atmosphere, and are thought to occur by impulsive releases of magnetic energy stored around starspots. Large flares (so called “superflares”) generate strong high energy X-ray and ultraviolet emissions …

The Space Weather Operational Readiness Development (SWORD) Center: a new NASA center of excellence at CU

Thomas Berger

(CU Boulder)

The Space Weather Operational Readiness Development (SWORD) Center is a new international, multi-disciplinary focal point where space weather researchers, operational forecasters, industry partners, and the space weather community will collaborate on transformative research to improve forecasts …
