NASA Exoplanet Query

Tier: 3-Advanced

Since 1992 over 4,000 exoplanets have been discovered outside our solar system. The United States National Aeronautics and Space Administration (NASA) maintains a publicly accessible archive of the data collected on these in comma separated value (CSV) format.

The objective of the NASA Exoplanet Query app is to make this data available for simple queries by its users.

Requirements & Constraints

  • The Developer should implement a means of efficiently loading the exoplanet CSV data obtained from NASA to minimize any delays when the application starts.
  • Similarly, the Developer should utilize a data structure and search mechanism that minimizes the time required to query the exoplanet data and display the results.
  • The Developer will need to review the Exoplanet Archive documentation to understand the format of the data fields.

User Stories

  • User can see an query input panel containing dropdowns allowing the user to query on year of discovery, discovery method, host name, and discovery facility.
  • User can also see 'Clear' and 'Search' buttons in the query input panel.
  • User can select a single value from any one or all of the query dropdowns.
  • User can click the 'Search' button to search for exoplanets matching all of the selected query values.
  • User can see an error message if the 'Search' button was clicked, but no query values were selected.
  • User can see the matching exoplanet data displayed in tabular format in an results panel below the query panel. Only the queriable fields should be displayed.
  • User can click the 'Clear' button to reset the query selections and clear any data displayed in the results panel, if a search had been performed.

Bonus features

  • User can see the host name as a hyperlink to NASA's Confirmed Planet Overview Page for that planet
  • User can click on the host name to display the Confirmed Planet Overview Page in a new browser tab.
  • User can see icons (such as up and down symbols) in the column headers
  • User can click on the up symbol to sort the rows in the results panel in ascending order on the values in that column.
  • User can click on the down symbol to sort the rows in the results panel in descending order on the values in the column.
