Deep craters

I read that there are deep craters on Mars. I forgot what the depth of one of these craters is, but it is much deeper than any crater the rover has passed. It is speculated that the extreme depth of this crater make it possible for the air pressure to be more than on the surface. Again, speculation that the atmosphere could be closer to the atmosphere on earth. There is so much misinformation about Mars, that my first question is, are there really deep craters on Mars. This is one of few websites that is not a conspiracy website. It is actually science driven site, so I would appreciate if anyone can answer this question. Also, if it is possible that a crater can be extremely deep, is there a possibility that the speculation that the atmosphere would be different than the surface? If all of these are possibilities, is it possible to measure the atmospheric pressure on a future rover mission? Since the rover will not be able to travel to the extreme depth because of the terrain, is it possible for the rover to drop some type of instrument into the crater that would be able to measure and transmit data back to the rover and the rover can transmit data back to earth? If this entire scenario sounds ridiculous, please tell me it is. I won't be surprised. Thanks.

We have a ton of stuff to discover about Mars.Shure, deep metor craters. why not. We already have lava tube tunnels....the chance of being made into a habitat makes these very interesting....still.....Elon Musk seems worried that he may never get there, interesting.....Space,,,the Final Frontier.,,, Hello Jim..... on this forum messages sometimes (most times),,move slow..ive been here decades..seen it from the start..yes pure science here.(or at least we try). although none of us know enough...Welcome..

Hellas Basin located in the southern hemisphere of Mars is the largest known impact created in the solar system.

The average atmospheric pressure on Mars is 7 millibars. In the basin pressures average 13 millibars.

So many post, too little results. How about Images? How to we post them.

If you want to revive this forum, these conditions must be met.

There is a new upwelling of science. We must make this sight user friendly.


I replied to post Ten minutes ago. Still can not see the reply.

I called myself a weatherman on this forum. In fact I am a metrologist. A degreed individual indeed.

Would love to discuss the Levin experiments and microclimate phenomena

Yet here I am...


Maybe tomorrow...

That's so sad.

A great song.

Sorry I had to spell it out..

Sorry just got this post to keep pounding.
Vince gill sang, "nobody answered when I called your name."

Still have a few pearls as Winston would say lol.

Hello JM..... time moves much slower than Elon Musk on this board...... eventually someone on Mars,, may...(or may not read) read this... I see Barsoomer is absent..sad... times are sad with this virus...even bandwidth when its needed most may become scarce...the tunnels of mars..i guess will interest me till I die... I too have done some (not all!) of the research.. habitat/installation/dwelling???...Like Elon,,I worry that I may never know...anyway.... the curse of old age.....the way we (the World)are going with technology ....death will soon be and you and Horton,Winston,Ben,Barsoomer,,,,,
the ones here to keep a dream alive,,, sad but I feel Important.....SOOOOOOOOO then......we are commited to keep the dream alive... that Man may one day walk on another World!!!............oh,,I don't worry about my GOD...I take him with me in my heart, soul and body.

Recently lost my IP address ...scary.. Security is tight now.(the stuff I went thru to just get a PING)....steps I went thru with techs that couldn't disclose their location... I wonder about the alert level of our military...hmmmm
Thanks to the Server that keeps this Forum idea how it is managed....Richard...or whoever it is..My hats off to you..Sir or Madam

Slower than Elon Musk. Now that's funny right there I don't care who you are..

Appropriate for the deep craters topic, the rocks hundreds of feet below the ocean bedrock solid surface of the Pacific on Earth. Various locations discussed, various microbe types, various energy and 'nutrient' types.
Have to finish reading this to comment in detail.
Having difficulty here with the virus conditions. It seems to be in control currently. Hope all are well. Good to read some ongoing info.
