Episode 617: Q&A 114: Why Isn't There A Microscope On Mars? And More... Featuring Stella Kafka from AAVSO

In this week's questions show, I explain why it doesn't make sense to send a microscope to Mars, how we could use a black hole to see a reflection of Earth and see dinosaurs, and why we don't just send a solar sail down to the Sun.
