Walkabout the Galaxy
Astrophysics and Astronomy | Physics
We explore an exoplanet system where the orbits of the planets are at right angles to each other. A chunk of rock trailing the Earth around the Sun may be a chunk of the Moon, and we take a look at some of the more interesting ways of getting into space and traveling long distances once we're there.
If you don’t have the time to wait around for that coarse-grained gabbro to cool from magnesium rich and iron rich magma, try basalt for a chemically equivalent fine-grained and fast-cooling solution. Simply take the handy pouch of low-viscosity mafic lava, remove from its planetary heat source, and watch its low-viscosity spread over your desired surface before it quickly and efficiently cools in place. Whether you need more lunar mare, Venusian plains, or a generic Mars rock, reach for basalt. Basalt: Full spectrum – full synergy (Porsche).
