The Mission summaries include a table of timekeeping values for each sol of the mission's landed operations.

What's in the table

Each row of the Mission time table includes time values and the sun's position specific to the rover's or lander's position at local true solar noon on that particular sol. See Time on Mars for details of the particular measurements. The columns are:

  • Sol - the sol count of the mission, beginning with landing. Clicking on a sol will open the Sol summary table to that sol.
  • HLST - Hybrid Local Solar Time (used by MER Spirit and Opportunity and by MSL Curiosity rovers).
  • LMST - Local Mean Solar Time (used by InSight lander).
  • SCLK - the master spacecraft clock counter.
  • UTC - the date and time on Earth, in Coordinated Universal Time.
  • Solar longitude - the solar longitude angle (generally written Ls or Ls), in degrees.
  • Solar Azimuth - the solar azimuth, in degrees.
  • Solar Elevation - the solar elevation, in degrees.
  • Sun distance - the distance to the sun, in astronomical units (AU).

Filtering and sorting the table

Some table columns can be filtered and sorted by clicking on the symbol in the column header and selecting from the available options. For example, you can sort a column in ascending or descending order. You might be interested in viewing rows after sol 1000, in which case you would select "Greater Than" and enter "1000" as the value before clicking the Filter button at the bottom (see the figure below).

To return the table to its original state, you can undo your sorting and filtering options, or simply click the "Reset table" button in the toolbar at the top of the window.

Exporting the data

You can export the table data to a PDF file or Excel-formatted spreadsheet. Click on the File button in the toolbar at the top of the window and select the desired output format. You may have to wait a few seconds as the data are compiled for output.
