About

Vissiniti is the website of Margaret McMurphy*, an amateur planetary scientist and aspiring screenwriter.

She has three ambitions over the next year: to finish her screenplay, to work with other writers, and to embark on a PhD in planetary science [well, maybe not…not next year anyway]. Beyond that, she is open to suggestions. The moons of Mars, perhaps.

She hosts this site for her own entertainment where she talks about planetary science, sci-fi and anything where she can weave in a circumventous route back to asteroids, comets, meteoroids, meteors and meteorites, in fact or fiction.

Her exploration of space rocks in science fiction has seen her compile the Index of Moving Pictures about Asteroid and Comet Threats, and since planetary scientists are obsessed with acronyms, you can call it IMPACT.

But science fiction isn’t science fiction forever. You only have to read a few classic Robert Heinlein novels to realise that, or listen to Elon Musk talk about going to Mars (…please take me with you).

If you don’t find the subject of asteroid spectral types and taxonomies too tedious, she has written a popular essay covering the half a century of asteroid classification systems, a read that might just keep you busy for the same length of time.

Prior to that, she undertook a deep dive into the compositions of spinel group minerals in meteorites that took many months to compile, but shelved it due to lack of inspiration (actually, it defeated her, but it may resurface one day).

One flew east, one flew west…recalling what another McMurphy said, “a little change never hurt, a little variety,” so you may see articles on this website on subjects completely unrelated to planetary science and wonder what on earth they are doing here.

Her current script is as much psychological thriller as it is science fiction.
