Probing Dust and Water in Martian Atmosphere with Far-Infrared Frequency Spacecraft Occultation
Ananyo Bhattacharya, Cheng Li, Nilton O. Renno +2
Airborne dust plays an active role in determining the thermal structure and chemical composition of the present-day atmosphere of Mars and possibly the planet's climate evolution o…
Highly depleted alkali metals in Jupiter's deep atmosphere
Ananyo Bhattacharya, Cheng Li, Sushil K. Atreya +12
Water and ammonia vapors are known to be the major sources of spectral absorption at pressure levels observed by the microwave radiometer (MWR) on Juno. However, the brightness tem…
Revealing the Mysteries of Venus: The DAVINCI Mission
James B. Garvin, Stephanie A. Getty, Giada N. Arney +36
The Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission described herein has been selected for flight to Venus as part of the NASA Discover…
Jupiter's Temperature Structure: A Reassessment of the Voyager Radio Occultation Measurements
Pranika Gupta, Sushil K. Atreya, Paul G. Steffes +12
The thermal structure of planetary atmospheres is an essential input for predicting and retrieving the distribution of gases and aerosols, as well as the bulk chemical abundances.…
The Origin and Evolution of Saturn: A Post-Cassini Perspective
Sushil K. Atreya, Aurélien Crida, Tristan Guillot +5
The Saturn System has been studied in detail by the Cassini-Huygens Mission. A major thrust of those investigations has been to understand how Saturn formed and evolved and to plac…
Revelations on Jupiter's Formation, Evolution and Interior: Challenges from Juno Results
Ravit Helled, David J. Stevenson, Jonathan I. Lunine +7
The Juno mission has revolutionized and challenged our understanding of Jupiter. As Juno transitioned to its extended mission, we review the major findings of Jupiter's internal st…
Lightning generation in moist convective clouds and constraints on the water abundance in Jupiter
Yury S. Aglyamov, Jonathan Lunine, Heidi N. Becker +7
Recent Juno observations have greatly extended the temporal and spatial coverage of lightning detection on Jupiter. We use these data to constrain a model of moist convection and l…
The water abundance in Jupiter's equatorial zone
Cheng Li, Andrew Ingersoll, Scott Bolton +20
Oxygen is the most common element after hydrogen and helium in Jupiter's atmosphere, and may have been the primary condensable (as water ice) in the protoplanetary disk. Prior to t…
Deep Atmosphere of Venus Probe as a Mission Priority for the Upcoming Decade
James B. Garvin, Giada N. Arney, Sushil Atreya +7
This is a white paper submitted to the Planetary Science and Astrobiology Decadal Survey. The deep atmosphere of Venus is largely unexplored and yet may harbor clues to the evoluti…
Exploration of the Ice Giant Systems: A White Paper for NASA's Planetary Science and Astrobiology Decadal Survey 2023-2032
Chloe Beddingfield, Cheng Li, Sushil Atreya +9
Ice giants are the only unexplored class of planet in our Solar System. Much that we currently know about these systems challenges our understanding of how planets, rings, satellit…
Deep Atmosphere Composition, Structure, Origin, and Exploration, with Particular Focus on Critical in situ Science at the Icy Giants
Sushil K. Atreya, Mark H. Hofstadter, Joong Hyun In +3
A comprehensive exploration of Uranus and Neptune is essential to understand the formation and evolution of the giant planets, in particular, solar system, in general, and, by exte…
Key Atmospheric Signatures for Identifying the Source Reservoirs of Volatiles in Uranus and Neptune
O. Mousis, A. Aguichine, D. H. Atkinson +5
We investigate the enrichment patterns of several delivery scenarios of the volatiles to the atmospheres of ice giants, having in mind that the only well constrained determination…
Scientific rationale for Uranus and Neptune in situ explorations
O. Mousis, D. H. Atkinson, T. Cavalié +53
The ice giants Uranus and Neptune are the least understood class of planets in our solar system but the most frequently observed type of exoplanets. Presumed to have a small rocky…
The Origin and Evolution of Saturn, with Exoplanet Perspective
Sushil K. Atreya, Aurelien Crida, Tristan Guillot +3
Saturn formed beyond the snow line in the primordial solar nebula that made it possible for it to accrete a large mass. Disk instability and core accretion models have been propose…
Giant Planet Observations with the James Webb Space Telescope
James Norwood, Julianne Moses, Leigh N. Fletcher +8
This white paper examines the benefit of the upcoming James Webb Space Telescope for studies of the Solar System's four giant planets: Jupiter, Saturn, Uranus, and Neptune. JWST's…
New insights on Saturn's formation from its nitrogen isotopic composition
Olivier Mousis, Jonathan I. Lunine, Leigh N. Fletcher +4
The recent derivation of a lower limit for the N/N ratio in Saturn's ammonia, which is found to be consistent with the Jovian value, prompted us to revise models of S…
Scientific rationale of Saturn's in situ exploration
O. Mousis, L. N. Fletcher, J. -P. Lebreton +47
Remote sensing observations meet some limitations when used to study the bulk atmospheric composition of the giant planets of our solar system. A remarkable example of the superior…
Saturn's Exploration Beyond Cassini-Huygens
Tristan Guillot, Sushil Atreya, Sébastien Charnoz +2
For its beautiful rings, active atmosphere and mysterious magnetic field, Saturn is a fascinating planet. It also holds some of the keys to understanding the formation of our Solar…
