It is a long way to get there.Let me give u a critical command sequence that I was involved in many years ago.We are trying to cut off some TwT to save power . I don't remember but I think it was 273 so u transmit that command to the satellite and it took 15 min for it to get there . To avoid any mistakes the satellite transmits the command back to me. so to round trip it it has taken 30 minutes. So now I sent the execute tone while holding the original command in the satellite. Now the satellite receives the execute command and transmits that info to me. So 1 hour later I have executed a critical command.

there are several reasons for that-
1) mars is far, far away...still in our solar system but the distance still runs into millions of km
2) limited speed of the satellite.......satellites might work on solar power or liquid fuel. any how, it can only reach a limited speed. if for example, the satellite travelled at the speed of light, it could already be there by the time i started writing this answer. however, in the history of science, technology and aeronautics, man has never been able to reach the speed of light or anywhere even near it....therefore, it takes a long time for a satellite to reach mars from the earth.

The distance is so great that even at light speed it would take an hour or four. Since we haven`t broken that law yet it will take. I believe a year or two to get there at the speeds we are now capable of.

Because Mars is about 300 million miles away, and a spacecraft maxs out at about 70,000 Mph?

Its kinda far away. It takes approx 20mins for radio waves to go between earth and mars so it would take much longer for us to go as we would be going slower(so we wouldn't die horrible deaths on the way)

Because of the distance from earth.

Because of the speed limit in space!!!

because of the mass of the satelite, and the laws of intertia and gravity.

Because it is really far away
