Official Mars Mission patch
NASA explains it better below...
"It is true that Earth and Mars are converging (you're now 300 miles closer), but even at closest approach the two planets are separated by a gulf of tens of millions of miles. From such a distance, Mars looks like a star, an intense yet tiny pinprick of light, never a full Moon.
"Now, in August 2007, Earth is catching up to Mars from behind. Relative speed: 22,000 mph. In December, Earth overtakes Mars, still moving rapidly but never approaching the Red Planet any nearer than the gap between lanes: about 55 million miles.
"Mindful that the two planets are converging, NASA chose this time to send its Phoenix Lander to Mars. Launched in June 2007 from Cape Canaveral, Phoenix is slated to land in late May 2008 on a Martian arctic plain where Phoenix's robotic arm will dig in the dirt hunting for, among other things, habitats for microbial life. Only to Phoenix, when it gets very close to Mars next year, will the red planet actually rival the Moon in apparent size.
"So … you should forget about Mars on August 27th, right?
"Not so fast. While there won't be Two Moons on August 27th, there will be Two Eyes. At 3 o'clock in the morning on that date, Mars will rise in the eastern sky alongside the red giant star Aldebaran. The two red lights side-by-side will resemble two eerie, unblinking eyes. This is worth waking up for!
If you've been following the adventures of Spirit and Opportunity, you know that Mars is currently experiencing a planet-wide dust storm. Rust-colored dust is choking the air and dimming sunlight, causing problems for the two solar-powered rovers. During the past month, they've had to "stand-down"—no roving or digging or even communicating with Earth at times—in order to conserve power.
(And you're now 1000 miles closer to Mars!)
The Mars Hoax email first appeared in 2003. On August 27th of that year, Mars really did come historically close to Earth. But the email's claim that Mars "would rival the Moon" was grossly exaggerated. Every August since 2003, the email has staged a revival; it is as wrong now as it was then.
Nothing seen through the narrow corridor of a telescope's eyepiece feels or looks as large as a full Moon.
