How would decomposition work in space?

[Grand Lander]

Kind of a strange question but yer.

Here's a scenario.

You land on the moon and you cant get back (for what ever reason) and you die on the moons surface in your suit.

How would decomposition take place?

[Nibb31]

There are bacteria in your body and inside the suit, so I suppose they would be able to perform some of the decomposition work until the seals on the suit degrade due to the thermal cycles and any atmosphere is vented.

Depending on whether your corpse is in the shade or in direct sunlight, you will either freeze or roast or go through thermal cycles of both. After a while, you will probably end up looking like a frozen carbonized chicken
