They go really fast
The rockets have heat cells on the rocket
It does to some extent. Rocky meteors typically burn up as they pass through our thick atmosphere. Nickel-iron meteors can burn up, but usually have the mass to punch through to some degree.
Most do burn up entirely but the very largest ones do not completely burn up.
It depends on the size and constitution of the meteoroid that burned up. Some will burn up in any layer of the atmosphere, some meterorites will make it to Earth's surface, and some meteroids will skip off the atmosphere and head back into space. However, meteor showers occur in the mesosphere.

The rockets have heat cells on the rocket
They're designed to withstand a great deal of heat and also be very aerodynamic to minimize drag. Of course when things go wrong, sometimes they do burn up – we saw that with the Columbia tragedy.
They burn up because of friction in the atmosphere
True. The vast majority of meteoroids burn up in the atmosphere, and reach the ground only as dust, after drifting around in the atmosphere for some time. (The stuff you wipe off the top of the TV set? Some of it is probably meteor dust.)

In the atmosphere
No. The atmosphere burns up the meteorite.
Most rockets are designed to jettison off before breaking the Earth's atmosphere. There are parts that comprise the secondary push, while in orbit, that burn up when falling back towards home. Anything else out there is littering the way that satellites and junk does.
They may burn up while travelling through the earth's atmosphere.
