I would encourage you to check out this post from Tilly Bridges. Her analyses of trans allegory in popular media are always fascinating! This one is absolutely spot on. For anyone not in the know: ‘Per aspera ad astra is a Latin phrase that translates literally as “through asperities (hardships, adversities, rigours) to the stars.”‘ (Wikipedia) Thus, Ad astra per aspera would roughly translate to “To the stars through adversity.”
Tilly promises a three-part series on the topic of this episode of Strange New Worlds. I’m looking forward to the rest of the series.
