NASA major announcement on Thursday about life on the red planet

Do you know how long they can remain dormant for?

Space is the perfect freeze drier.

If they are frozen inside a rock at say minus 200 degrees
& are protected from most of the radiation.
Why couldn't they last forever?

You won't get any moisture inside a porous rock.

How would envision they would get protection from radiation

They could be inside some block of rock and ice floatin around out there

How would envision they would get protection from radiation

Inside a large rock containing iron - like so many meteorites -
they would have some protection from radiation.

Remember - there could be billions of microbes inside a rock &
only one would have to survive to multiply when it landed in some nice warm water.

Forever is a long time and the law of phyics indicate that everything will decay over time.... includign every atom if we keep expanding forever.

I don't know what is the microbes you refer. I expect that cells will not survive very well by organic molecules will, e.g. RNA and imno acides ...etc.

I was thinking it would be something like an underground shopping mall, or similar.

You know, something cool, to entice tourism.

But women get their eggs frozen all the time for use later in reproduction techniques.
Sperm is also frozen from donors.
I see no reason why microbes frozen for millions of years could not come back to life -
well at least some of them - & it takes only one to reproduce to create a billion more very quickly.

If we do find microbes on Mars it is quite likely that they originally came from Earth.
Maybe our whole Milky Way galaxy has been seeded this way?
