<p><strong>Introduction:</strong>  In its investigations of the planet Mercury, NASA’s MESSENGER returned an immense amount of data detailing the dynamic surface of our solar system’s innermost planet. As the European and Japanese space agencies prepared for the launch of BepiColombo, the next mission to explore Mercury, BepiColombo’s project science team asked NASA to produce a new portal within the Solar System Treks suite (https://trek.nasa.gov) featuring data returned by MESSENGER from Mercury. This new portal would be used both for mission planning and for public outreach by the BepiColombo mission. While initially populated with Messenger data, the portal is also being designed to facilitate visualization, analysis, and dissemination of data from BepiColombo after it commences science operations in orbit around Mercury. The initial release of the Mercury Trek in 2019 shortly followed the launch of BepiColombo on its journey to Mercury.</p> <p><strong>The Mercury Trek Portal:</strong>  The initial release of Mercury Trek in July 2019 featured data products from the Mercury Dual Imaging System (MDIS) instrument that operated aboard NASA’s MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) mission while in orbit around Mercury from 2011 to 2015. These products include the MDIS Global Mosaic, MDIS BDR Global Mosaic, MDIS Color Global Mosaic, MDIS MD3 Color Global Mosaic, MDIS Enhanced Color Global Mosaic, MDIS LOI (low-incidence angle) Global Mosaic, MDIS Global Digital Elevation Model (DEM), and MDIS Color Hillshade Global map derived from the DEM. An updated release in June 2020 featured enhanced search capabilities, an updated user interface, the option to have user interface control labels in either English or Japanese, and the addition of numerous new data products. These include high resolution MDIS mosaics, DEMs, and slope data for selected regions, and gravimetric maps including crustal thickness, gravity anomaly, gravity degree strength, and gravity disturbance. Also included are 1:5M geologic maps for the Beethoven, Discovery, Kuiper, Michaelangelo, Shakespeare, Tolstoj, and Victoria regions.</p> <p>Mercury Trek’s data visualization capabilities make it easy to stack and blend different data layers in order to optimize depictions of a wide variety of surface features. Data products can be viewed in equatorial, or polar projected views, or on an interactive 3D globe. The Trek interface allows the user to maneuver a first-person visualization of “flying” across the surface of the Mercury.</p> <p>Analysis tools make it easy to measure distances (either straight-line or along a user-defined path) and to create elevation profiles for surface features. Users can draw user-defined bounding boxes across Vesta’s terrain to generate STL or OBJ files for 3D printing. They can also draw a freehand path anywhere across the surface and have Vesta Trek return a QR code that can be scanned into a smartphone (Android or iOS). The smartphone can then be placed into a pair of inexpensive cardboard-compatible goggles. The user will then be able to fly their defined path in virtual reality.</p> <p>We intend to continue working with the BepiColombo mission and the greater planetary science community to enhance the new Mercury Trek portal with additional data products, and solicit suggestions from the community.</p> <p><strong>One Component in an Integrated Suite:</strong>  Mercury Trek is one of a growing number of portals in NASA’s Solar System Treks Project, available at https://trek.nasa.gov. NASA's Solar System Trek online portals for lunar and planetary mapping and modeling provide web-based suites of interactive data visualization and analysis tools to enable mission planners, planetary scientists, students, and the general public to access mapped data products from past and current missions for Mercury, the Moon, Mars, Vesta, Ceres, Titan, seven of Saturn’s smaller icy moons (Dione, Enceladus, Iapetus Mimas, Phoebe, Rhea, and Tethys), Ryugu, and Bennu. As web-based toolsets, the portals do not require users to purchase or install any software beyond current web browsers. These portals are being used for site selection and analysis by NASA and a number of its international partners, supporting upcoming missions.</p> <p><strong>Acknowledgements: </strong>The authors would like to thank the Planetary Science Division of NASA’s Science Mission Directorate, the Science Engagement and Partnerships Division of NASA’s Science Mission Directorate, and the Advanced Explorations Systems Program of NASA’s Human Exploration and Operations Mission Directorate for their support and guidance in the development of the Solar System Treks.</p>

Abstract. Since 2005 the Mars Advanced Radar and Ionospheric Sounding experiment (MARSIS) aboard Mars Express has acquired a unique dataset on the ionosphere of Mars made up of ionospheric soundings taken by the instrument working in its active ionospheric sounding (AIS) mode. These soundings play a role similar to those of modern Terrestrial digisondes in the analysis of our planet ionosphere and have allowed us to dramatically improve our knowledge about the Martian ionosphere. This paper describes this kind of data, which are available from the public Planetary Science Archive, and introduces the MAISDAT tool developed by the European Space Agency to analyze and derive the vertical profile of electron density. Comparisons with radio occultation profiles obtained from Mars Express Radio Science instrument are performed to validate the procedure used in this study.

Mars Express is the first planetary mission accomplished by the European Space Agency (ESA). Launched in early June 2003, the spacecraft entered Mars's orbit on Christmas day of that year, demonstrating the new European commitment to planetary exploration. Following a failed attempt in the mid-1980s, two valid proposals for a European mission to Mars were submitted to ESA's decision-making bodies in the early 1990s, in step with renewed international interest in Mars exploration. Both were rejected, however, in the competitive selection process for the agency's Science Programme. Eventually, the Mars Express proposal emerged during a severe budgetary crisis in the mid-1990s as an exemplar of a “flexible mission” that could reduce project costs and development time. Its successful maneuvering through financial difficulties and conflicting scientific interests was due to the new management approach as well as to the public appeal of Mars exploration. In addition to providing a case study in the functioning of the ESA's Science Programme, the story of Mars Express discussed in this paper provides a case study in the functioning of the European Space Agency's Science Programme and suggests some general considerations on the peculiar position of space research in the general field of the history of science and technology.

During the last five years, the term mobile commerce (m-commerce) has appeared in the vocabulary of business people and researchers. Historically and conceptually, m-commerce can be regarded a new phase in electronic commerce (e-commerce). Although the term was introduced without a clear meaning and it is still lacking a single widely accepted definition, most people would say that the term m-commerce refers to e-commerce activities performed by people while on the move. Thus, m-commerce involves e-commerce transactions where a mobile terminal and a wireless network are used to conduct them. Therefore, m-commerce takes advantage of the e-commerce infrastructure developed for Internet e-commerce. Although in some cases an m-commerce transaction might be an alternative to a regular e-commerce transaction (such as buying a book) performed using a workstation and wired network, in many cases this is not the situation. The limitations of the mobile device - for instance, user interface limitations - are such that it is not attractive to perform typical Internet e-commerce transactions on them. Wireless technologies, combined with so-called ‘Internet-enabled’ terminals, constitute an ideal platform to realize new types of e-commerce transactions that are not possible or reasonable for wired terminals. The small and light, yet powerful, mobile terminals are almost always carried by their owners, just like wallets or watches. They can indeed also store electronic cash, credit card information, tickets, certificates of the Public Key Infrastructure (PKI), and so forth. Thus, they can assume the role of an e-wallet, as well as function as authentication and authorization devices in various contexts.

Abstract. The Coastal Observing System for Northern and Arctic Seas (COSYNA) was established in order to better understand the complex interdisciplinary processes of northern seas and the Arctic coasts in a changing environment. Particular focus is given to the German Bight in the North Sea as a prime example of a heavily used coastal area, and Svalbard as an example of an Arctic coast that is under strong pressure due to global change.The COSYNA automated observing and modelling system is designed to monitor real-time conditions and provide short-term forecasts, data, and data products to help assess the impact of anthropogenically induced change. Observations are carried out by combining satellite and radar remote sensing with various in situ platforms. Novel sensors, instruments, and algorithms are developed to further improve the understanding of the interdisciplinary interactions between physics, biogeochemistry, and the ecology of coastal seas. New modelling and data assimilation techniques are used to integrate observations and models in a quasi-operational system providing descriptions and forecasts of key hydrographic variables. Data and data products are publicly available free of charge and in real time. They are used by multiple interest groups in science, agencies, politics, industry, and the public.

<p>NASA’s Solar System Treks program produces a suite of interactive visualization and AI/data science analysis tools. These tools enable mission planners, planetary scientists, and engineers to access geospatial data products derived from big data returned from a wide range of instruments aboard a variety of past and current missions, for a growing number of planetary bodies.</p><p>The portals provide easy-to-use tools for browse, search and the ability to overlay a growing range and large amount of value added data products. Data products can be viewed in 2D and 3D, in VR and can be easily integrated by stacking and blending together rendering optimal visualization. Data sets can be plotted and compared against each other. Standard gaming and 3D mouse controllers allow users to maneuver first-person visualizations of flying across planetary surfaces.</p><p>The portals provide a set of advanced analysis tools that employed AI and data science methods. The tools facilitate measurement and study of terrain including distance, height, and depth of surface features. They allow users to perform analyses such as lighting and local hazard assessments including slope, surface roughness and crater/boulder distribution, rockfall distribution, and surface electrostatic potential. These tools faciliate a wide range of activities including the planning, design, development, test and operations associated with lunar sortie missions; robotic (and potentially crewed) operations on the surface; planning tasks in the areas of landing site evaluation and selection; design and placement of landers and other stationary assets; design of rovers and other mobile assets; developing terrain-relative navigation (TRN) capabilities; deorbit/impact site visualization; and assessment and planning of science traverses. Additional tools useful scientific research are under development such as line of sight calculation.</p><p>Seven portals are publicly available to explore the Moon, Mars, Vesta, Ceres, Titan, IcyMoons, and Mercury with more portals in development and planning stages.</p><p>This presentation will provide an overview of the Solar System Treks and highlight its innovative visualization and analysis capabilities that advance scientific discovery.  The information system and science communities are invited to provide suggestions and requests as the development team continues to expand the portals’ tool suite to maximize scientific research.</p><p>Lastly, the authors would like to thank the Planetary Science Division of NASA’s Science Mission Directorate, NASA’s SMD Science Engagement and Partnerships, the Advanced Explorations Systems Program of NASA’s Human Exploration Operations Directorate, and the Moons to Mars Mission Directorate for their support and guidance in the development of the Solar System Treks.</p>

Many businesses use email as a medium for advertising and they use emails to communicate with their customers. In the email world, the most common issue that remains unresolved even now is spamming or in other terms unsolicited bulk email. Currently, there is no common way to regulate the practices of an email sender. This proposed system is to formulate a protocol common for all the ESPs or inbox providers and a centralized system that will easily find the spammers and block them. By this method, the Email Service Providers (ESPs) or Inbox Providers need not wait for the sender behaviour and then take actions on the sender or sender domain or sender IP address. Instead, they can get the sender history of reputation from blockchain where the ESPs or Inbox Provider provides a score based on the emails they have received from the sender. The ESPs can get the Public Sender Score(S3) from the mobile application or web application which provides the score management user interface and APIs. The email marketers can also monitor their score through the application.
