After breaking out of the earth's atmosphere, into the dark and cold of space....for example if you are heading for the moon....what is the temp?

Current background microwave radiation suggests its about 3° Kelvin

There is no temperature in space. Temperature is a property of matter, and space being a vacuum can therefore not have a temperature.
An object in space will have a temperature, but that will depend on many factors, not the least of which being its own thermal properties. In sunlight objects can warm up in space, but in shadow they will get very cold. Of course, for a three-dimensional object this causes problems because one side is always shaded and getting cold while the other is warming up in sunlight. On the Apollo spacecraft they got around this by having the whole spacecraft slowly rotate so it was heated evenly. They also gave it a highly reflective outer skin so it would reflect heat rather than absorb it, thus slowing its warming.
So whether your object will get cold or hot depends on where your object is and what it is made of.

Temperature is a measure of heat and heat can only exist in matter. Space is a vacuum so no Temp can be measured. Total absence of heat.
Absolute zero.

If you are not exposed to the Sun, almost zero kelvin, if you are exposed to the Sun, about 400 kelvin.
