How do I change (the size of) the underlying planet for measurements?

I am a high school teacher with a brand-new ConnectED K-12 account for ArcGIS Online and am trying to figure out the very basics to use this for planetary exploration.

 

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

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

both of these servers are from thare_USGS

 

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?
