TUSCALOOSA, Ala. – During August Mars will be closer to
Earth than it has been in 60,000 years. Throughout the month the
planet will be fairly easy to find as Mars appears red or orange
as it rises in the night sky. On Aug. 27, Mars and Earth will
pass each other with just 34.65 million miles separating them.
“We will never have a closer look at Mars without getting
our feet off the ground,” said Dr. Bill Keel, professor of
astronomy at The University of Alabama. “The telescopic view
will show why people have spent decades arguing about what we do
and do not see on the Martian surface.”
However, as close as Mars will be – which is closer to
Earth than any other major planet, except Venus, can come –
the gap is still daunting. According to Keel, at its closest,
Mars still will be 150 times the moon’s average distance and
look smaller on the sky even though Mars actually is about twice
the size of the moon.
The two planets will pass each other because the Earth
travels around the sun faster than Mars does. The Earth rotates
once around the sun about every 365 days. It takes Mars 687 days
to make the same trip.
Keel said the proximity of the 2003 approach makes it an
especially good time to send landing craft to Mars, which
accounts for the two NASA rovers and a European mission.
There will be two public viewings of Mars, sponsored by The
University of Alabama astronomy department, through a 10-inch
refracting telescope on top of UA’s Gallalee Hall.
The first will be Tuesday, Aug. 26 at 8 p.m. Dr. Ron Buta,
professor of astronomy, and Keel will talk about the close
approach of Mars to Earth and then take everyone to the roof to
view the red planet. There will be an encore of this
presentation and viewing on Friday, Aug. 29 at 8 p.m. On both
dates, the program starts in room 227 of Gallalee Hall.
Gallalee Hall is located on the UA campus near the
intersection of Hackberry Lane and University Boulevard in
Tuscaloosa. For more information, contact UA’s department of
physics and astronomy at 205/348-5050.
This chance to view Mars up close is a perfect opportunity to
introduce children to astronomy, as well as thrill star-gazers
of all ages.
The department of
physics and astronomy is in the College
of Arts and Sciences, the University’s largest division
and the largest public liberal arts college in the state, with
approximately 5,500 undergraduates and 1,000 graduate students.
The College has received national recognition for academic
excellence, and the College’s students have been selected for
many of the nation’s top academic honors, including 13 Rhodes
Scholarships, 14 Goldwater Scholarships, seven Truman
Scholarships, and 15 memberships on USA Today’s Academic
All-American teams.
