Mars 2003 with The Albuquerque Astronomical Society

What Makes This Summer so Special?

Since Earth is closer to the Sun, and orbits faster than Mars, Earth orbits past Mars about every 25 months.  This close pass is called Opposition. 

This year's opposition occurs at a time when, because of its elliptical orbit, Mars is closest to the Sun.  This is called Perihelion. 

In addition, Earth's elliptical orbit is at it's furthest point from the Sun in July.  This is called Aphelion

It is this nearly simultaneous combination of Aphelion, Perihelion, and Opposition that makes this year's event special.

When Does it all Come Together? 

At 3:51 a.m. MDT on August 27, 2003, Mars will be within 
34,646,418 miles (55,758,006 kilometers) of Earth.

Will I Really Notice a Difference?

To the casual viewer looking up in the night, Mars will become the brightest object in the night sky (other than the moon), growing to a magnitude of -2.9.

Looking through a telescope, the view of Mars will certainly be the best since our last opposition in 2001, and theoretically better than ever before,

Where Can I See Mars With a Telescope?

TAAS offers two public viewing events, specifically geared towards watching Mars.

• Mars Madness at UNM - Friday, August 22, at the UNM Campus Observatory
• Mars Madness at Oak Flat - Saturday, August 23, at the Oak Flat Picnic Grounds

Each event is free, and begins at dusk.  TAAS astronomers will provide their personal telescopes for you and your family's viewing pleasure.  Each event is subject to weather.
