New Hubble images of the Red Planet

Right: An animation of Mars showing four hemispheric views at 90 degree intervals as seen by the Hubble Space Telescope between April 27 and May 6, 1999.
The telescope's Wide Field and Planetary Camera 2 snapped these images between April 27 and May 6, when Mars was 54 million miles from Earth. From this distance the telescope could see Martian features as small as 12 miles wide. The telescope obtained four images, which, together, show the entire planet. Each view depicts the planet as it completes one quarter of its daily rotation.

is centered near another volcanic region known as Elysium. This area shows many small, dark markings that have been observed by the Hubble telescope and other spacecraft to change as a result of the movement of sand and dust across the Martian surface. In the upper left of this image, at high northern latitudes, a large chevron-shaped area of water ice clouds mark a storm front. Along the right limb, a large cloud system has formed around the Olympus Mons volcano.
features a dark area known as Syrtis Major, first seen telescopically by the astronomer Christiaan Huygens in the 17th century. Many small, dark, circular impact craters can be seen in this region, attesting to the Hubble telescope's ability to reveal fine detail on the planet's surface. To the south of Syrtis is a large circular feature called Hellas. Viking and more recently Mars Global Surveyor have revealed that Hellas is a large and deep impact crater.
See for yourself
If you would like to see Mars for yourself on the 4th of July, it's easy! After sunset (or around 9:30 p.m. local time) the Red Planet can be seen approximately 30 degrees above the southwestern horizon from mid-latitude sites in the Northern hemisphere. The "Red Planet" will appear just over 5 degrees to the left of the bright bluish star Spica. Mars, shining brightly at magnitude -0.4, has a distinctive pumpkin color. You won't discern as much detail as the HST, but it's still a satisfying sight.
