In the frenzy to find life elsewhere in the solar system, Mars or the outer gas giant planets

Wouldn't surprise me one bit. Next to the Jovian icy moons Ceres should be a major sample & submersible rover target.

It does sort of surprise me. I've never considered life being on Ceres.

It's a minor planet that's estimated to have more total water than Earth has fresh water, about 200 million cu/km.

If its core is heated by radioactive decay a habitat could be under the surface ice. Add hydrothermal vents and chemosymthesis and you have an environment much like the vents under Earth's oceans, and they're loaded with critters.

Ceres has also been suggested as a refueling depot for a deep space infrastructure. Use solar or nuclear heat sources to break water down into hydrogen & oxygen and you can gas up.

It's rounded by its gravity... It's a planet.

I would classify it as such, but the same IAU pinheads that took away Pluto's planet status kept Ceres out too.

The last Metroid is in captivity at Ceres station.

I'm confused as to why Dwarf Planets are somehow immune from being counted alongside their larger brothers. There's a pretty clear natural definition between a planet that's round, and an asteroid that's odd shaped.

The International Astronomical Union (http://www.iau.org) makes those decisions, and a lot of people disagree with excluding the self-rounded "minor planets." One of the prime movers in getting them excluded was Neil deGrasse Tyson.

Roundness isn't the only thing though, otherwise all the moons would be considered planets.

Right, but there's a pretty clear difference between a planet that orbits the sun directly, and a moon, which orbits a planet.

Back on topic here.

 

Its good to know that life exists on other planets, but why do we care about it, if its just bacteria or micro organisms?

 

We get to say there is life outside our planet but that is all it really achieves.

 

Do we really think that finding bacteria on Ceres will help anything? 

Increase funding to find life - unlikely

Stop religions- unlikely

 

It seems like it is only for bragging rights for the country that does it first.

Abductee, Barney Hill, made a claim that there may be an alien base on Ceres.

If we find that life - of any form - exists on more than one body within our Solar System then it greatly increases the chances that life is common throughout the Universe, rather than life on this planet being an oddity and rare. The more common life is, the greater chance there is other intelligent life.

Count me as one that strongly disagrees with them.

you are correct for our lifetime, but future generations could benefit. What if we could get a sample of a life form (bacteria) for example? Could we use it for a cure? New medicine?  Of course there are some too who would want to know what kind of new weapons we can make.
