Background: I am a high school teacher with a brand-new ConnectED K-12 account from ESRI for ArcGIS Online and am trying to figure out the very basics to use this for planetary science.
I have loaded maps of Mars, but my measurements are as if the lat/longs were on Earth.
What I've done so far:
Loaded the maps
When I turn on the measurement tool, the widths of common features (e.g. Olympus Mons) are about twice what you'd expect (checked vs JMARS), as if the lat/longs were on Earth rather than Mars.
How do I change (the size of) the underlying planet for measurements?

- basemap: ArcGIS Server - Mars MDIM2.1 Basemap
- layers: ArcGIS Server - Mars Global GIS Overlay Service
