Mars TOP STORY
Mars is peppered with craters. Scientists have deduced that the red planet is struck by around 200 meteoroids every year that dig out new craters.

Comet Siding Spring Next to Mars
This composite NASA Hubble Space Telescope Image captures the positions of comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet, which happened at 2:28 p.m. EDT October 19, 2014. The comet passed by Mars at approximately 87,000 miles (about one-third of the distance between Earth and the Moon). At that time, the comet and Mars were approximately 149 million miles from Earth.
Humans have long dreamed of traveling to Mars, hopscotching across the solar system and fanning out into the cosmos beyond.
Mars Exploration Rover Opportunity captured images of a comet passing much closer to Mars than any previous known comet flyby of Earth or Mars. The images of comet Siding Spring were taken against a backdrop of the pre-dawn Martian sky on Sunday (Oct. 19).
All three NASA orbiters around Mars confirmed their healthy status Sunday after each took shelter behind Mars during a period of risk from dust released by a passing comet.
Jared Espley and Michelle Thaller talk about the close encounter between Mars and Comet Siding Spring at the Oct 17, 2014.
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars.
This artist's concept depicts the early Martian environment (left) - believed to contain liquid water and a thicker atmosphere - versus the cold, dry environment seen at Mars today (right).
During an October 9 press briefing at NASA headquarters, panelists discussed the Earth and space-based assets that will be in position to observe the October 19 flyby of Mars by comet C/2013 A1, also known as comet Siding Spring. These assets include NASA's iconic Hubble Space Telescope and spacecraft orbiting and roving Mars.
NASA's MAVEN spacecraft has reached Mars and it is beaming back "First Light" images of the Red Planet's upper atmosphere. The data could help researchers understand what transformed Mars from a hospitable planet billions of years ago into a desiccated wasteland today.

Four possible landing sites are being considered for the ExoMars mission in 2018. Its rover will search for evidence of martian life, past or present.
Regional dust storm activities over Northern Hemisphere of Mars - captured by Mars Color Camera on-board Mars Orbiter Spacecraft from altitude of 74500 km on Sep 28, 2014 High resolution image.
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has obtained its first observations of the extended upper atmosphere surrounding Mars.
India's Mars Orbiter Spacecraft has captured its first image of Mars. The image was taken from a height of 7300 km; with 376 m spatial resolution. Larger image. Another image shows the limb of Mars.
India successfully placed its Mars Orbiter Mission spacecraft into orbit around Mars this evening - and in so doing it became the first nation to put something into Mars orbit on its very first attempt.
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars' orbit at 10:24 p.m. EDT Sunday, Sept. 21, where it now will prepare to study the Red Planet's upper atmosphere as never done before. MAVEN is the first spacecraft dedicated to exploring the tenuous upper atmosphere of Mars.
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is nearing its scheduled Sept. 21 insertion into Martian orbit after completing a 10-month interplanetary journey of 442 million miles.
