The recently published Interstellar Probe (ISP) study report describes a pragmatic mission concept with a launch window that starts in 2036 and is expected to reach several hundreds of astronomical units past the heliopause within a time frame of ≥50 years (https://interstellarprobe.jhuapl.edu/Interstellar-Probe-MCR.pdf). Following the ISP report, ...

In the summer of 2017, the Cassini mission concluded its nearly 13 years orbiting Saturn with a series of daring dives between the rings and the upper reaches of Saturn's atmosphere. This last phase of the mission, called the Grand Finale, revealed a highly variable equatorial ionosphere dominated by a large influx of ring material from Saturn's D ...

The Cassini spacecraft made in-situ measurements of Titan's plasma environment during 126 close encounters between 2004 and 2017. Here we report on observations from the Radio and Plasma Waves System/Langmuir probe instrument (RPWS/LP) from which we have observed, primarily on the outbound leg, a localized increase of the electron density by up to ...

A surprisingly strong influx of organic-rich material into Saturn's upper atmosphere from its rings was observed during the proximal obits of the Grand Finale of the Cassini mission. Measurements by the Ion and Neutral Mass Spectrometer (INMS) gave insights into the composition of the material, but it remains to be resolved what fraction of the inf...

Icy satellites of the outer solar system have become the primary target for planetary exploration because of their relevance to understanding of solar-system evolution and to the origin of life. Despite this importance, it remains unclear how different combinations of tectonic deformation, climate conditions, and surficial and interior processes ha...

During its thirteen-year long mission in the Saturnian system, the Cassini spacecraft routinely used Titan, Saturn’s largest moon, for performing its gravity assists. The problem of determining the gravity field of Titan by performing a precise fit of Cassini’s orbit to the available Doppler tracking data was reviewed in this study. The knowledge o...

L’histoire de la carte de France à l’échelle 1:80 000, souvent désignée carte d'état-major, débute en 1808. Malgré toutes les difficultés qui ont présidé à ses relevés, à sa gravure et à sa publication, cette carte constitue la souche de la cartographie de la France pendant plus d’un siècle. On en compte pas moins de 14 dérivés directs dont certain...

L'ingénieur Louis Capitaine est impliqué à plusieurs titres dans la production de la carte de Cassini. Il est actionnaire de la compagnie qui la publie et il dirige son exécution au cours des années 1780. Sur cette base, il obtient l’autorisation de produire une carte générale de l’ensemble du royaume, par réduction au quart de celle de Cassini en ...

The Saturn Kilometric Radiation (SKR) was observed for the first time during the flyby of Saturn by the Voyager spacecraft in 1980. These radio emissions, in the range of a few kHz to 1 MHz, are emitted by electrons travelling around auroral magnetic field lines. Their study is useful to understand the variability of a magnetosphere and its couplin...
