The space-heads among you have undoubtedly heard about the Curiosity rover’s first significant discovery: the remnants of an ancient streambed on Mars, which would seem to indicate the presence of water in the planet’s history. This jagged pile of alluvial rock and dust may not look like much, but it brings to mind one of my favorite pieces of Martian historical arcana.
For a time in the late 19th century, it was believed that there were canals on Mars.
