This is NASA’s best shot at finding life on Mars

NASA’s Mars rover, Perseverance, is on its way to the Red Planet with the goal of seeking out evidence of life there. How will we know that evidence if we see it? And how can we be sure we’re not “discovering” Earth microbes that hitched a ride with the rover? Here’s what NASA’s scientists, engineers, and their “planetary protection lead” have to say.

What do you think Perseverance will discover on Mars?

Didn’t David Bowie already sort this out?

[vhol]

She seems so excited with her job, that's always a positive sign !! :D

Finding a fish walking in Mars is what I would love to see.

You all have great passion for your jobs.. good luck with the mission.

Some alien is watching this mission like we look at a cave man who just made a shiney new club.

Life was just a horror movie. Let's not make it a documentary lol

Fun fact: "Jezero" means lake in many Slavic languages. It's like an Easter egg / inside joke by the person who named it like that.

Just finished watching the launch of the rocket now here i am lol

Loved hearing Moogega Stricker talk! She has an infectious passion for her job. Love it.

[dmkoslicki]

I love the passion that Dr. Stricker shows for her work! Great way to get people engaged in and excited about science!

Very informative video. Especially about the choice of location on Mars and the parallels that it has with fossilized records on Earth. Most other videos on this mission only focus on the rover, its instruments and how it's getting to Mars.

[PavelMiklyaev]

Ok, you've sent rover on Mars, but you could make video conference without glitches

[whatthefunction]

Today I learned that we have already sent life to Mars...

[ooooneeee]

That planetary protection officer is one of those unknown heroes not wearing a cape. Also she loves her job, which is heartening.

[arhamshafi]

Even just finding trails in martian sand would greatly raise scientists concern. That's how much we're obsessed with lifeforms.

[Neyney_]

Man, that rover got some mad rims on those wheels.

[yummysatay]

Noted. We will send praises when everything went well in the near future. Can't wait for results from this and the other two missions from UAE and China.

[CSABHOF]

Jezero means "lake" in Czech

Probability of living life on Mars now is greater than 0.5, , IMO.
