Carnival of Space Week 51

Carnival of Space Week 51 is up at astroengine.

I contributed my article on the Finnish solar wind riding electric sail, which is nearing readiness for flight testing

Centauri Dreams talks more about the electric solar space sail.

Colony Worlds talks about the need for ants for space colonies. Bees could have problems with the different or lack of magnetic fields. Ants might be needed to take the place of Bees for pollination.

Ethan Siegel ponders what it would take to destroy the Universe. Using a particle accelerator with a radius that would span 10**14 kilometres (or from Earth to the nearest star system) might be able to do it)

Go to astroengines for a lot more.
