Viewing Gale Crater from Earth

Will it be possible on August sixth to view the landing of the MSL telescopically from Earth?

The Phoenix landing descent was imaged from the Mars orbiter MRO satellite with the HiRISE telescope onboard at a distance of 760 kilometers. The telescope was just able to 'see' the lander and parachute from that Mars position.

The landing will be imaged from the new MSL landing descent vehicle directly with onboard cameras, and certainly the MRO/HiRISE telescopic camera will be employed in catching views before, during, and after the landing.
Even large Earth based telescopes and the Hubble cannot resolve objects the size of automobiles on the Martian surface from the tens of millions of miles distance between the two planets.

With the landing scheduled for late night Aug 5, 2012, some release and coverage during the descent, and further images in the weeks following the landing will be available from the HiRISE search page by typing 'MSL', 'Mars Science Laboratory', or 'Curiosity' in the topmost search term textbox.

I should have added that the actual landing sequence will be on August 5, 2012, not the 6th as indicated in the topic here.
The landing will be late in the evening, from about midnight on the US East coast to about 10pm on the West coast. Other geographic timing adjustments can be made from that estimate, or, a search of the 'MSL landing time' should give a reliable source specific by time.

The YouTube JPL news collection of videos shows the technical challenge of the procedures being tested during landing, in this video of 5 minutes duration.

In regard to the topic question about the resolution of very small items in telescopic images, I also wait for further refinements of light based imaging resolution in the microscopy realm, where we are bound by at the limits to view of some of the available information with impressions blending to distortions. We are blocked from actually seeing the real image that exists, and there are always new machines being built that give an extension to more detail and hidden content. Satellite relay of imaging in orbiting telescopes is slower but very detailed.

Thank you very much Dana Johnson for the informative response!

To more correctly answer your question, this is a page from the Hubble space telescope returns from near Earth distance, and this is the JPEG large sized image view of Mars, with the Gale crater area in view at the lower left area.
Just visible are the linear aligned volcano peaks. The UV to infra-red views combined still give too non-delineated shading to allow even the highest peaks on Mars to be more than faint spots. Gale is so small it probably is just a couple pixels in this highest resolution view. The older laptop I am using today will not allow a sub-pixel alteration attempt to find the crater and MSL/Curiosity landing site.

This is about the best view from Earth thus far.

The landing:
"Curiosity's landing is expected to reach Earth at about 10:31 p.m. PDT on Aug. 5 (early Aug. 6, EDT and Universal Time), as originally planned.", from the article in, July 27, 2012, about the adjusted flight of the Odyssey orbiter spacecraft at Mars to allow for a direct observation and immediate transmission of the landing progress. This will be the first knowledge of the landing activity.

Odyssey has been retransmitting rover data from the MER rovers during the past eight years of what is now a ten year mission starting in October,2001. From the Odyssey site, "Odyssey relayed the first images from the Opportunity rover on landing day and has continued to send back 85% of all data from the twin rovers."

A link to the MSL - Curiosity mission page. A countdown timer is at the bottom of the page, and there is a link to advice on viewing the landing.

Our Curiosity is about write a new section on the natural history of Mars as it gives us an understanding of current human capabilities on the surface.

NASA TV link for watching the landing from some regions. Is this link working for non-US locations?

MRO/HiRISE will be a few minutes too late in orbital flight to see the actual landing, so we will miss the 'from a distance' parachute images we saw during the Phoenix mission.
Hopefully we can find the instruments on the early HiRISE imaging, with some viewers sub-pixel high resolution alterations.
Will the onboard cameras of Curiosity give a near real-time view transmitted through Odyssey?

Yes, Nasa TV works fine from my location in Norway, and i think the rest of the world.

With all the noise about localized 'benefits' being 'national' in calculation, and no way to 'auto-check' a page in distant sourcing I had to ask. Thanks, Mizar. Some in this country would have us believe we are always fighting a mysterious 'serpent' or unknown danger beyond national borders. People are quite fine natured unless they choose otherwise, nearly everywhere, but as with animals like dogs, the territorial impulse is one of the easiest localizing generators of a lack of humaneness. Science is always best and most accurate when it is universally agreed and applied. Pleased to know the world can see the landing on NASA TV and see the Curiosity results after this weekends landing.
The landing slow-down is rather impressive over a few minutes timing.
The nylon descender cord, can it be judged as not of full length, for an adjusted touchdown? As I understand it, the touchdown release happens as a product of a reduced weight measurement for the lander body, giving an uneven terrain control over descent travel. Two measures, one from the Skycrane as distance, and one from the Curiosity lander wheels would be a safe measure of touchdown, I would think, but, if only one of the two is scheduled, the lander weight would be measured from the Curiosity wheels to be safest as a machine judgement. Even some new automobiles on Earth have automated 'parallel parking' and backup avoidance guidance these days.
The actual weight judgement on Mars, not the nearly one ton Earth weight, but the Mars reduced weight impulse of approximately 750 pounds, will give a control to the separation action. Hopefully there will be no spinning or swaying motions.
Describing the Earth equivalent weight difference, with a stripped version of the lander. We have the benefit of reduction of gravity impulse on Mars, giving us a 'smarter' machine for the stresses of landing. More content in machinery for the efforts expended in landing on Mars.


Regardless of the slant taken in viewing results of past missions, this new rover landing is far more competent in all measures than the prior successes in roving Mars.
We have a number of rover models over the last fifty years.

A HiRISE/MRO view of the landing during the descent stage. Earlier, the claim was made that MRO would be about two minutes too late in orbital position to see the descent and landing.
Somehow they were able to give us a historical record of the parachute phase of the descent.

Now we can wit for detailed lander images which can show the instrument package.

If only we could solve all our Earth based problems this well.

No instruments as yet from the small closeup released. Altered to find a few wheels, possibly the microwave antennae at the shadowed rear lower corner of the body, and a general glare blur concentrated along the core and mast central area. The body is outlined somewhat. Need more wavelengths and better software for more detail.
HiRISE is 'down' today, so we will have to rely on the Tiffs released thus far.
Altered here, and about 3X. Converted to JPEG after attempting to reverse pixelation of the original. The view will improve perhaps.
