Not only is she a great scientist; she's an absolutely awesome writer.

"Space should be for everyone who lives on this singular planet, not a playground for the wealthy or a frontier to dominate. (...)
The more we learn about the Universe, the more we should cherish our perfect and irreplaceable home."

And unafraid to call it like it is:

"I’m leaving because I want to tell the truth."
