Physical Characteristics
Mars has only a quarter the surface area of the Earth and only one-tenth the mass, though its surface area is approximately equal to that of the Earth's dry land because Mars no longer possesses oceans. The solar day on Mars is very close to Earth's day: 24 hours, 39 minutes, and 35.244 seconds.

“Life on board a pleasure steamer violates every moral and physical condition of healthy life except fresh air.... It is a guzzling, lounging, gambling, dogs life. The only alternative to excitement is irritability.”
