Chelsea:
gravity  :-\

barman:
This gif is zero percent scence and 100 percent bullshit. First of all, rockets can produce continuous thrust, so you can leave any object at any speed as long as the net force points up. Second, even without continuous thrust, you don't need these speeds if staying in orbit is all you want. Low Earth orbit satellites move at about 8 km/s (17900 mph). 25031 mph is what you need to get out of our planet's gravitational well altogether.
And these rockets don't even represent the escape velocities written below the planets. Earth's is over twice as large as that of Mars, yet the rockets seem to be moving at roughly the same speed :-X

Chelsea:
haha :D

dunno why, but I knew, that gif is shit :D (like everything at demotywatory.pl) :D but wanted to know your opinion ;)

Wait, its an orbiting speed, not speed "fromwards" Earth.
