Positioning and Sensing in 6G: Gaps, Challenges, and Opportunities
Among the key differentiators of 6G compared to 5G will be the increased emphasis on radio-based positioning and sensing. These will be utilized not only for conventional location-aware services and for enhancing communication performance but also to support new use case families with extreme performance requirements. This article presents a unified vision from stakeholders across the value chain in terms of both opportunities and challenges for 6G positioning and sensing as well as use cases, performance requirements, and gap analysis. Combined, this motivates the technical advances in 6G and guides system design
The Saturn Ring Skimmer Mission Concept: The next step to explore Saturn's rings, atmosphere, interior, and inner magnetosphere
The innovative Saturn Ring Skimmer mission concept enables a wide range of
investigations that address fundamental questions about Saturn and its rings,
as well as giant planets and astrophysical disk systems in general. This
mission would provide new insights into the dynamical processes that operate in
astrophysical disk systems by observing individual particles in Saturn's rings
for the first time. The Ring Skimmer would also constrain the origin, history,
and fate of Saturn's rings by determining their compositional evolution and
material transport rates. In addition, the Ring Skimmer would reveal how the
rings, magnetosphere, and planet operate as an inter-connected system by making
direct measurements of the ring's atmosphere, Saturn's inner magnetosphere and
the material owing from the rings into the planet. At the same time, this
mission would clarify the dynamical processes operating in the planet's visible
atmosphere and deep interior by making extensive high-resolution observations
of cloud features and repeated measurements of the planet's extremely dynamic
gravitational field. Given the scientific potential of this basic mission
concept, we advocate that it be studied in depth as a potential option for the
New Frontiers program.Comment: White paper submitted to the Planetary Science and Astrobiology

A UV-to-NIR Study of Molecular Gas in the Dust Cavity around RY Lupi
We present a study of molecular gas in the inner disk (r ∼ 0.4± 0.1 au; {r(narrow,H₂)} ∼ 3± 2 au). The 4.7 μm ¹²CO emission lines are also well fit by two-component profiles ( {{r}broad,CO} =0.4± 0.1 au; {{r}narrow,CO} =15± 2 au). We combine these results with 10 μm observations to form a picture of gapped structure within the mm-imaged dust cavity, providing the first such overview of the inner regions of a young disk. The HST SED of RY Lupi is available online for use in modeling efforts
