Have you been to Mars??? Not? So, here are some awesome photos from NASA, great photos of mars

Yesterday’s announcement by NASA of the discovery of water ice on Mars by its Phoenix Lander probe made big news everywhere. The discovery involved the observation of water ice sublimating into the air - that is, the water went from solid to vapor state without reaching the liquid stage. The Martian atmosphere has perfect conditions for sublimation - extremely thin, dry and cold. How cold? Well, you can check the Live Martian Weather Report, with data from a station on board the Phoenix Lander. Today will see a high temperature of a toasty -26 degrees F.

This series of images is a false colour time-lapse sequence of the Martian sunrise. The bottom image is the first one taken just before sunrise. Notice how the Martian sky gets light before sunrise. This is due to all of the dust in Mars’ atmosphere. Light from the sun is caught and scattered in the dusty atmosphere making the sky light before the sun even rises.

High, wispy clouds cover a large portion of Mars, seen in this, the first true-colour image of Mars generated with the OSIRIS orange (red), green and blue color filters. The image was acquired by an instrument on the ESA’s Rosetta probe on Feb. 24, 2007 from a distance of about 240,000 km. Image resolution is about 5 km/pixel.

This is a true colour image of an actual sunset on Mars taken by Pathfinder. Twin Peaks can be seen on the horizon. The sky around the Sun is a pale bluish colour. The image was taken around 4pm.

This image is very similar to the one above except that the sun has already set. The image was taken as part of a twilight study which indicates how the brightness of the sky fades with time after sunset. It was determined that the Martian sky stays bright for as long as two hours after the Sun has set. Again, this phenomena is due to the height of the dust in Mars atmosphere, indicating that Martian dust extends very high into the atmosphere.

Mars’ northern orange sky and horizon, seen by NASA’s Phoenix Mars Lander. The lander’s solar panel and Robotic Arm with a sample in the scoop are also visible. The image was taken by the lander’s Surface Stereo Imager looking west during Phoenix’s Sol 16 (June 10, 2008), or the 16th Martian day after landing. The image was taken just before the sample was delivered to the Optical Microscope. (NASA/JPL-Caltech/University of Arizona/Texas A&M University)

Dust devil from above. This image taken by the Hi-RISE Camera aboard NASA’s Mars Reconnaissance Orbiter catches a dust devil blowing across the Martian surface. Dust devils generally form in the afternoon because the sunlight needs sufficient time to warm the surface. When this image was taken, the local time was about 3:08 p.m. The bright material is the dust within the vortex, and a dark shadow cast by the dust devil is visible to the left. The diameter of this dust devil is about 200 meters, but at the surface it is probably much smaller. Based on the length of the shadow in this image, the dust devil is on the order of 500 meters tall. (NASA/JPL/University of Arizona)

Martian skies seen above a rolling horizon in this image, part of a larger image called the “McMurdo” panorama, taken in the Martian winter of 2006 by NASA’s Mars Exploration Rover Spirit. The tracks in the soil are from Spirits wheels as it rolled through the area earlier. (NASA/JPL/Cornell)

Clouds above the rim of “Endurance Crater” in this image from NASA’s Mars Exploration Rover Opportunity. These clouds occur in a region of strong vertical shear. The cloud particles (ice in this martian case) fall out, and get dragged along away from the location where they originally condensed, forming characteristic streamers. Opportunity took this picture with its navigation camera during the rover’s 269th martian day (Oct. 26, 2004). (NASA/JPL)

Early Spring Dust Storms at the North Pole of Mars. Early spring typically brings dust storms to northern polar Mars. As the north polar cap begins to thaw, the temperature difference between the cold frost region and recently thawed surface results in swirling winds. The choppy dust clouds of several dust storms are visible in this mosaic of images taken by the Mars Global Surveyor spacecraft in 2002. The white polar cap is frozen carbon dioxide.

Higher in the Martian skies, we see one of its two moons. The HiRISE camera onboard the Mars Reconnaissance Orbiter acquired this dramatic view of the Martian moon, Phobos, on 23 March 2008, from a distance of 6,800 kilometers. The illuminated part of Phobos is about 21 km across. The most prominent feature is the large impact crater Stickney, in the upper left. With a diameter of 9 km, it is the largest feature on Phobos.

High ice cloud over Mars’ limb. This composite of red and blue Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) images acquired on 6 July 2005 shows an isolated water ice cloud extending more than 30 kilometers (more than 18 miles) above the Martian surface. Clouds such as this are common in late spring over the terrain located southwest of the Arsia Mons volcano. (NASA/JPL/Malin Space Science Systems)

What more do we know about Mars’ atmosphere? It’s hundreds of times thinner than Earth’s atmosphere and is made of 95% carbon dioxide, 3% nitrogen, 1.6% argon, and contains traces of oxygen, water, and methane. We also know, from observations that it can support dust storms, dust devils, clouds and gusty winds. With an amazing number of six current live probes exploring Mars (two rovers, a lander, and three orbiters), there are many thousands of images available. Only a few, however show atmospheric phenomena. Presented here are some of the best images of Martian atmosphere (and beyond) in action
