The Surface Stereo Imager onboard NASA's Phoenix Mars Lander observed clouds drifting across the horizon in the early morning on the 119th sol, or Martian day, since landing (September 25, 2008). Clouds were observed each night after Sol 80 (August 15, 2008) as the atmospheric temperature decreased.
How long is a day on Mars? Great question! There are two ways to determine the length of a day on any celestial body. The sidereal day and the solar day. A sidereal day on Mars is the length of time that it takes the planet to rotate once on its axis. A sidereal day on Mars lasts 24 hours 37 minutes and 22 seconds. The solar day is how long it takes the Sun to return to the meridian. This position changes slightly each day, but a solar day on Mars lasts 24 hours 39 minutes and 35 seconds.

Looking more habitable by the day
somebody shoot a rocket with some seeds to mars and see if anything sprouts.

Remember when NASA wanted us to believe Mars had a red sky?
"Look folks, the images show a red sky on Mars!" - cut to decades later - Oh sorry about that image of a blue sky folks, we weren't trying to mislead you, we just used a red filter to highlite the details on Mars that's all."
G-damn liars is what they are, I physically can't force myself to believe anything they tell me anymore, makes me ill.
