okay but whoa 

peridot is chemically unstable on the earth’s surface

Homeworld gems have been there, they know which gems can’t handle earth for long.

her mission was to gather data and transmit it back.

nobody answered her distress signals.

she’s using her gem’s energy really quickly (explosive energy attacks?)

the data on the cluster and the cluster experiment itself are probably highly illegal

if so, she’s a loose end 

I don’t think she was meant to make it back alive.
