Re: Marsis to probe for subsurface water

This is very exciting to me. There is little doubt that there is frozen water on Mars. But permafrost is a difficult rock to work with.

There's some evidence of Martian volcanic activity in the recent (geologically speaking) past. I believe it likely there is liquid water near the surface of Mars.

If the Marsis antenna does find near surface liquid water, this will be very valuable information.

    Yes. I think Mars is more volcanically active than it's given credit for. And I wouldn't be surprised if liquid water still exists in large near-surface aquifers, too.
    I find it very exciting, m

Re: Marsis to probe for subsurface water

Much about this radar has been mentioned under the Mars express thread but ok it would seem that the first boom is out to be followed by others. Not to mention it did not kill itself from whipping as the simulator had indicated.

(looking in the Unmanned Probes topic...)  I see your April 29 post but don't have time right now to read the entire 10 page thread.
The Marsis antenna is only 1.8 kilograms. Seems like it'd be worthwhile to use something like it to probe the moon. Or asteroids & comets for that matter. We'll have to wait and see if it unfolds without a hitch.

The Oberg article is good. Thanks for the link.

Excellent!
    So far so good.

Re: Marsis to probe for subsurface water

The problem with the antenna array was its long length. I think 30 feet or something like that, which when it was to extend would whiplash about, but it appears that the fear was unfounded.
I hope it finds lots of sub surface deep pocket of water and soon.

Re: Marsis to probe for subsurface water

It appears that one of the segments did not fully deploy on the antenna as hoped it would.
Delay hits Mars radar deployment
or from Space.com
I guess we will be a wait and see mode for a while at least.
