Not of this planet

No I am not talking about some of the customers we get.

I came across this picture on the NASA web site and their copyright is acknowledged.

mars sunset

Spirit acquired this view of the Martian sunset from Gusev Crater on April 23, 2005. Using data from images such as this, scientists have learned that twilight on Mars is longer than on Earth, lasting for up to two hours before sunrise or after sunset. Dust high in the atmosphere scatters light to the night side of the planet. Similar twilights are seen on Earth following major volcanic eruptions.

Put’s the pictures the permanent lookers get of the railway into perspective, Mind you they would have to pay something to get to Mars to take the picture above, in the case of the railway all they have to do is get in the way and pay nothing.
