Dinosaur-killing asteroid might have sent life to Mars, study shows

The colossal asteroid impact that killed off the dinosaurs may have sent the seeds of life to other planets and moons, according to a new study. Lifeforms may have even hitched a ride to Mars along one of the 360,000 large rocks that have made their way from the Earth to the red planet after asteroid impacts.

So these "lifeforms" were the 1st astronauts sent to space from Earth .....Long, long time before NASA

What we know about survival of bacteria even what has been found in the last 40 years (thermophiles in hot vents, bacteria deep underground and on the edge of space), it really is a matter of time before they discover bacteria on Mars, just out of sheer contamination.

More likely the other way round...

How can an asteroid impact on Earth send rocks from Mars to Earth?

We've visited many planets and moons with satellites... there is no life out there. Anywhere. Not a peep. Yet our own planet has life in every corner, mountain, ocean bottom, etc. I believe if life is out there it originated from Earth. There's no evidence to the contrary.

Probably the most ignorant statement I have seen on this forum.

We haven't even completely searched our own planet let alone any other, and you say we haven't found anything 'out there' by just 'passing by' ?

Haha wow... How many planets have we stepped foot on? One. How many satellites have we set foot on? One.

Just because the moon didn't have any life (supposedly),doesn't mean life can't be light years away. The rover we sent to Mars doesn't even look for life, it looks for the building blocks of life to see if it is habitable.

The only reason life thrives here is because the climate and geography allow it to. And after billions of years of the relatively peaceful creation of Earth ,life has survived long enough to survive and evolve until now.

There are plenty of satellites with a liquid ocean underneath their ice sheets. Are our own voyaging spacecraft advanced enough to look under miles of ice?

You'll never know how many nuggets are in a stream until you start picking up rocks.

I was implying that an asteroid wiped out Mars and sent seeds of life here...
