    Should you feel particularly ambitious about getting up early; Venus, Jupiter, and Mars are all visible in close proximity to each other before the the sky begins to lighten-up.

    (Note, I am on the east coast of the US. Posting here since I am unable to post on the Solar System News thread.)

    Speaking of Mars, want to calculate the distance to the red planet?

    Possibly a new thruster variant that will make interplanetary travel more practical:

    Still visible. It has been overcast for a while. Jupiter has now "risen" above Venus. Also have a full Moon now, making it a bit more difficult to see the planets.

    Why did Mars lose so much of its water?

    Unmentioned in the story (but hopefully mentioned by the researchers) is the lower surface gravity on Mars. That means the planet will cling to its atmosphere less tightly, so the same strength of solar wind would remove more atmosphere from Mars than from Earth.

    The Martian Moon Phoebus looks like it's very slowly being pulled apart by gravity http://www.space.com/31133-mars-moon-phobos-falling-apart.html
