Mars and the sun are directly opposite each other in Earth's sky today, which is why the formation is known as an opposition of Mars. You can watch two live shows about the Mars opposition here on Space.com beginning at 7 p.m. EDT tonight.

Calling all space cadets: Earthwatch wants volunteers to help search for life on Mars in what has to be the most entertaining April Fools' joke you'll see this year.
31 March 2014, 02:48 PM ET
Red Mars' close encounter with Earth, a 'red moon' total lunar eclipse (visible from North America) and the Lyrid meteor shower will highlight the month of April 2014. Also, the mornings and evenings will showcase Jupiter, Saturn and Venus.
31 March 2014, 09:50 AM ET
Mars and Earth will only be 92 million miles apart at closest encounter in April 2014, called ‘opposition’. Mars will appear red-gold, glowing brighter than first magnitude stars. Only Jupiter, the Moon and Venus before sunrise will be brighter.
28 March 2014, 03:18 PM ET
Twice in the past two weeks the Mars rover Opportunity has experienced "cleaning events" that have blown some of the rusty powder away, allowing more sunlight to fall on the solar arrays, giving the six-wheeled rover a seasonal power-up.
27 March 2014, 03:09 PM ET
A new Hubble image, captured on March 11, shows what appear to be two jets of dust coming off the nucleus of Comet Siding Spring, which on Oct. 19 will miss Mars by just 84,000 miles — about one-third the distance between Earth and the moon.
27 March 2014, 07:11 AM ET
NASA's plan to capture an asteroid and park it near the moon is only one step on the way to Mars, NASA chief Charles Bolden said Wednesday (March 26). The space agency is planning an ambitious mission to send a robotic spacecraft to an asteroid.
