How
to use Mars Mapper
The program always opens with the current Martian aspect presented
to Earth. You can step forward or backward in time (useful to
check recent images or sketches of Mars) in increments of one hour
or an Earth day (a Martian day is 24 hours and 37 minutes long),
or click the 'Reset to now'
button to return to the present. If you wish to display Mars for a
specific date (y/m/d
format) and time, simply enter the desired values and click the 'Recalculate' button to accept
them. Note: Mars Mapper
uses 24-hour format Universal
Time (UT), so UK-based observers should deduct one hour
from British Summer Time while it is in force. To preserve accuracy, you may only enter
dates and times between 1 May and 31 October 2018. |
