Depending on how 'clean' the spaceship is, there will be little

Never mind the spaceship it's the astronaut that will not be clean
enough; most of decomposition will happen because of the growth of
natural bacterias that people carry inside thir guts.

Assuming the body remains in pressurized environment it will decompose
unless the humidity is very low in which case it will mummify. If the
suit or ship is in near vacuum the situation is slightly different and
will lead to a different kind of mummification (freeze drying).
