Mars Perseverance

Gotta love the fact that Perseverance appears on the environmental sub-forum (because it's nuclear powered?) of a Prius sub-forum!

Does the fact that it uses an RTG to charge a Lithium-Ion battery pack make it a 'hybrid'?

 

The actual videos from the spacecraft are cool of the landing process.
Damn we have to live 10 years to get the rocks back...I have to eat my Wheaties and live the good life in hopes to make it.

 

Anybody know for sure where Mars is in the sky these days? Does it matter where on the globe you are?

N’mind; not that tricky:

Had my scope on it Oct thru Nov due to close approach...lost it now it is tinier.

 

Maybe here on a car site, since rumor is that the first contact Perseverance received after landing was a call inquiring about its extended warranty.

 

Now they will raise taxes to pay for this stuff they call space.

Keep working humans, maybe one day you will live on mars.

You will have to leave this forum since you will not have a prius.

I spent too many years under water to want to fly several months for the privilege on living under ground on Mars.
Unless they noodle out how to generate a magnetopshere on Mars, the 'scenery' on Mars is going to be fairly uninteresting.....

People sometimes ask me if I've ever been under the the Artic ice pack, and if so what it was like.
I tell them that it's exactly like being on the equator or anywhere else in the ocean, and it looks like the inside of a submarine.

 

Just to add:

• 0.095 psi - Mars atmospheric pressure
• 14.7 psi - Earth atmospheric pressure
• ~154 difference

Given the earth 0{2} ratio is about 20%, we could with a 100% oxygen level:

• 0.095 psi - Mars atmospheric pressure
• 2.94 psi - 100% Earth atmospheric pressure
• ~31 difference

The pressure difference means the 'suit' would have to be substantial, close to a vacuum suit ... the interior of a shallow water submarine.

Personally, I would want an inner mesh of kevlar for pressure with an outer layer of reflective layers. The idea is to keep the 'cold' out and the 'warm' in. But there remains a ballistics problem.

If (when) a meteor hits Mars and reaches the surface (likely), there will be a substantial outflow from the crater that spreads planet wide. With any reasonable Mars surface material density, these particle will easily pierce the suit and occupant.
