LA

Dashboards are views containinga grid-layout of different widgets within which data is displayed. Many dashboards have been pre-defined in collaboration with the Instrument Teams.

Users can also create their owndashboards containing a customised collection of widgetsin their preferred layout.Users can choose to share thesedashboards with other team members.

BepiColombo: The Mission

It will arrive at Mercury in late 2025, including several flybys of the Earth, Venus and Mercury along the way.

It consists of two orbiters: - Mercury Planetary Orbiter (ESA/MPO) - hosting 11 scientific instruments - Mercury Magnetospheric Orbiter (JAXA/MMO or 'Mio') - hosting 5 scientific instruments.

BepiColombo is a joint ESA/JAXA mission that launched on

20th October 2018

About: BepiColombo Quick-Look Analysis (QLA)

The BepiColombo Quick-Look Analysis (QLA) system is a web-based application being developed by the Science Ground Segment (SGS) team forthe BepiColombo mission. The QLA provides a means to interactively visualise and assess the science and housekeeping data products soon afterthe telemetry has been received from the spacecraft. This allows a preliminary analysis of the science products produced by the instruments as well as continous monitoring of the spacecraft and instrument health.By providing quick visibility of the data the system aims to facilitate the monitoring of the completion of the observations with respect to the scientific objectives and to feed this back into the mission planning process.

Data VisualisationData is displayed in the QLA through a number of different dashboard views. Each dashboardcan contain multiple widgets showing different types of related data (huosekeeping, science)with various plot types.

Each widget in a dashboard is a container with a set of common functionality for visualisingand interacting with the data - such as widgets for displaying charts, images, maps or tables.

Data Export - Data can be exported to CSV files, images or PDFs.

Interactive Plots - Data is loaded into the web browser which allows real-time interaction with the data - Data values and metadata are displayed when hovering the mouse over data points - Plot widget types support zooming and panning. - Some manipulation of data is possible, such as changing axis type (linear/logarithmic)

Interactive data- scale, zoom, pan- modify axes- export data

Data Linking - Linking several widgets allows actions performed in one widget to be applied to the linked widgets, facilitating the comparison of data.

Customisable - widgets can be added to custom dashboards by dragging them in from a widget menu. - the layout of the widgets can then be modified as desired.- this allows a user to more easily comparedifferent data types and across different instruments.

Saveable and shareable- the given state of a dashboard, such as time range selected and data processing level, is stored in the URL in the browser.- options set on each widget can also be stored in the URL

- this URL can be bookmarked to return to the QLA on a givendashboard in a given state- this also facilitates sharing data of interest with colleagues!

Performance

Advancements in web technologies mean thatvisualising and manipulating data in a web browseris a valid possibility.Even so, displaying many thousands to millions of data points is still a challenge.

- to reduce strain on the browser and its memory, data can be downsampled on the server. Higherresolution data is retrieved when a user zooms in. - to reduce the memory footprint on the server, data is streamed to the client in batches via parallel processing threads.

Rapid Access to DataSoon after telemetry has been retrieved from the spacecraft, raw and calibrated products are available to be displayed.
