Excerpt: The successful transport microbes would be dependent on three major factors: protection of the corpse, its storage, and the corpse’s flight time.
The body would have to be encased in a spacecraft for the microbes to survive passage through the atmosphere.
Along with this, it would need either to be kept in above-freezing temperatures that would allow for liquid water, or freeze-dried.
And, longer time spent floating in space will subject the corpse to higher amounts of cosmic radiation, limiting microbial survival.
Even if all microbes are killed, scientists say the corpse could spark new life if it landed on a planet which already hosts certain fundamental molecules, like the DNA building blocks triphosphates.
And, a new genesis would have a much better chance if entire ill-fated crew landed in the right environment.

The sun pushes out a lot of radiation, not only would the microbes be damage (maybe beyond saving), wouldn't any other cells/DNA be damage too?
There was a gentleman name Hirochi Ouchi who was working at the Tokaimura nuclear powerplant in 1997 which had a nuclear meltdown, causing Ouchi to be exposed to 17 sieverts (Sv) of radiation. At 8 Sv, it's considered fatal to a human, but he withstood it. Not only was his body severely burned, losing limbs and his skin literally melting off, his chromosomes were broken down within the cells. He did pass, unfortunately but he was kept alive for 83 days.
What I'm getting is what would the radiation measure if someone were to be suspended in space? Would it be higher/lower than the 17 (Sv) that Mr. Ouchi was exposed to? Could researches use the data collected from examining Mr. Ouchi to determine if this hypothesis could be justified?
BTW...there is a book written about Mr. Ouchi when he was hurt.

This sounds like the plot to a space zombies movie SPC Britanny *Winnie* Balthaser.
As somebody who went through the chemical-induced stopping of my heart which was electrically started 8 to 12 hours later, I recognize that life is not something to be toyed with and dead matter cannot be reanimated by mere humans no matter how brilliant.
In accordance with Einstein's theory of relativity, if the space vehicle travels faster than the velocity of light aging will be reduced; but, that won't help somebody already dead.
I concur with PO1 (Join to see)'s response in that unshielded radiation as the space vehicle passed by stars much brighter than our own sun would cause tremendous damage to body tissue.
