چکیده
Abstract In order to investigate the origin of Phobos and Deimos, Japanese Martian Moons eXploration (MMX) mission is scheduled for launch in 2024. MMX will make comprehensive remote-sensing measurements both moons return regolith samples from Earth. Geodetic gravity, shape, rotation parameter a body provides constraints on its internal structure reflecting evolution. Moments inertia are important parameters constrain mass distribution, but they have not been well determined yet. We discuss requirements related moments detect potential heterogeneity distribution inside Phobos. introduce instruments operational strategies meet requirements. present preliminary imaging strategy quasi-satellite orbit base shape model that expected be created at early stage mission. products including ephemeris, gravity field, Phobos, spacecraft importance only geodetic study, also interpreting data various selecting possible landing sites.

Art and science: geodesy in materials science.
A 3-dimensional model based on a molecular structural recipe having some unique and unexpected shape characteristics is demonstrated. The project was originally initiated to satisfy the aesthetic creative impulse to build a 3-dimensional model or sculpture. Further scientific investigation explained some important nanoscale structural observations that had been seen many years beforehand and mi...
متن کاملA clock network for geodesy and fundamental science
Leveraging the unrivalled performance of optical clocks as key tools for geo-science, for astronomy and for fundamental physics beyond the standard model requires comparing the frequency of distant optical clocks faithfully. Here, we report on the comparison and agreement of two strontium optical clocks at an uncertainty of 5 × 10(-17) via a newly established phase-coherent frequency link conne...
متن کاملBasic Science Investigations
18F-FDG is formed through radiochemical synthesis from cyclotron-produced 18F (K. Breslow, written communication, June 2000). Production of 18F is through proton bombardment of enriched 18O-water. 18F-fluoride is bound to 1,3,4,6-tetra-O-acetyl-2-O-trifluoromethanesulfonyl-Dmannopyranose (mannose triflate) under conditions of a stereospecific second-order nucleophilic substitution reaction, whi...
متن کاملEngineering Adaptive Digital Investigations using Forensics Requirements
A digital forensic investigation aims to collect and analyse the evidence necessary to demonstrate a potential hypothesis of a digital crime. Despite the availability of several digital forensics tools, investigators still approach each crime case from scratch, postulating potential hypotheses and analysing large volumes of data. This paper proposes to explicitly model forensic requirements in ...
