The planet Mars represents our actions, strength, force,  courage, and desires. It represents our sexual nature, and  men. Mars is ruled by the signs Aries and Scorpio, and it's manifestation can be constructive or destructive depending upon the nature of the aspect it is making in the natal chart.
 
Mars takes about two years to travel through the 12 signs of the zodiac, and stays in each individual sign for about 40 days.
 
On October 17, 2009, Mars entered  the sign Leo, where it will travel for the next eight months. Leo is the natural ruler of the fifth house of children, friends, love affairs and entertainment, so Mars in Leo will  relate to these matters in general, and there will be a focus relating to the issues of children on a collective basis.
 
Mars will retrograde at 19 degrees on December 20, 2009 until March 11, 2010.  At that time it will resume it's forward action completing it's cycle in Leo until June 6, 2010.
 
When Mars retrogrades people often complain of low energy, and subtle forms of manipulation can occur within personal relationships. Projects and situations can slow down, or be put on the back burner. When Mars slows down and become stationary retrograde, or when it begins to move forward after a retrograde, combative or combustive energy can occur. When Mars retrogrades it is a time to step back, and slow down the energy.
.
Mars goes stationary retrograde at 19 degrees of Leo on December 10- December 30, 2009, and if it is  creating a harsh angle to a personal planet in your chart between 16 and 21 degrees (planets in Leo, Scorpio, Aquarius, or Taurus) you may experience combustive or combative energy on a personal level.  Mars creating a hard angle in your chart  can also be responsible for accidents, sickness, colds, chills and fevers.
 
Mars retrogrades back  to 0 degrees on February 28, 2010 until March 21, 2010, and again if is creating a conjunction or harsh angle to a personal planet you will experience a lengthy period of stress or combative/combustive energy. Mars goes stationary direct on March 10, 2010 at 0 degrees it will only advance to 2 degrees by the end of the month.  Again, if this is hitting a personal planet in your chart between 0-4 degrees you will experience tension/stress or potential sickness and it is accident prone. By May 16, 2010 Mars will reach the 19 degree mark, where it went retrograde  in December, 2009.
