Many have been sent, although only around a third of missions actually got there. However, the number that were sent is around 42, with several planned by various agencies for 2010-2011 and beyond.
More missions have been attempted to Mars than any other place in the solar system, except the moon. Most of the attempts have failed. There have been 35 past missions. There are six active missions, and two future missions planned.
The U.S. has sent a number of space probes to the planet Mars. Several have been orbiting camera platforms, while others have been rovers or lander.
No manned missions to Mars have been sent, only unmanned ones.
no not yet .but only the probes have been sent there.
No living creature of any kind has been sent to Mars, not even microbes (all components of a spacecraft that will land on another body are sterilized before assembly).
none no rocket has ever flown to mars as it is to humid but nasa sent satellites over there many times and have sent rovers , little robots with cameras roaming around it, many ofd them are called mars rover then are named with a specific botname
Although several spacecrafts have been sent to Venus, no alien spacecrafts have been discovered on its surface.
N.a.S.A sent spacectafts to mares called mariner spacecrafts.

We have sent rovers to Mars but there have been no manned missions.

N.a.s.A sent the Apollo spacecrafts in space.
Probes, satellites, and rovers have been sent to the planet Mars. These devices have been able to gather data, pictures, and materials from the planet.
so far about 2-3 and some people might say there might still be life because the spacecrafts never went in some of the areas but most people believe that no life is ON mars!!!
You seem to be misinformed. The first US spacecraft was Mariner 10. This was followed by Messenger. There have not been others.
