Yo AWASH,
they take into account the gravity both both planets which determines the angle of ejection & entry.
The rockets give off huge amounts of gases which by Newtons third law generate a thrust and propell the rocket up the ground,through the atmosphere.
The computers controll the ejection of gases in the right amount and direction.

NASA has sent two robots to mars .
They are Spirit rover and opportunity. These are the robots. They are operated manually from advanced computers.
These two robots take the photographs of Mars and send it to the Earth. With this help, astronomers and scientists study about Mars, and it's surface.
MER-A (Mars Exploration Rover - A), known as Spirit, is the first of the two rovers of NASA's Mars Exploration Rover Mission. It landed successfully on Mars on 04:35 Ground UTC on January 4, 2004, three weeks before its twin Opportunity (MER-B) landed on the other side of the planet. Its name was chosen through a NASA-sponsored student essay competition.
MER-B (Mars Exploration Rover - B), known as Opportunity, is the second of the two rovers of NASA's Mars Exploration Rover Mission. It landed successfully at Meridiani Planum on Mars on January 25, 2004 05:05 Ground UTC (circa 13:15 local time), three weeks after its twin Spirit (MER-A) had landed on the other side of the planet.[1] Its name was chosen through a NASA-sponsored student essay competition.

To answer your question: Physics!
To make a joke at NASA's expense:
How many astronauts does it take to pilot the Space Shuttle?
One and a fifth

manual or auto-pilot.
but with current propulsion technology they will reach mars in 6 months time.
