This is what Mr. Sqyres said on 27/4:
April 27, 2005

A note to all you Opportunity fans: Get used to the current scenery, because we're going to be here awhile.

We are very optimistic that we'll be able to get out of here, but we're really going to take our time doing it. The first rule in a situation like this is "do no harm", which means that you don't rush anything. We're going to take lots of pictures of all the terrain around the vehicle, to get a very complete picture of the situation. We're going to do lots of testing with the rovers that we have on the ground to simulate the situation on Mars. This testing will be aimed not just at finding a plan that will work, but at finding the very best plan that will work. We may try quite a few small maneuvers with Opportunity that aren't intended to do anything other then help us gather more information... perhaps followed by even more testing. All of this is going to take a lot of time. But this is a very precious vehicle up there, in excellent health, and there's no reason to rush anything. I'll try to provide updates as the process moves forward, but the main message for now is to be very, very patient. No apparent progress in the images doesn't mean anything other than that we're being very careful to do our jobs right.

Flight Dir: So, last night, was the software update successful?

MER Driver: Yes

Flight Dir: I was going over the new rover commands... what's that new parameter for the forward motion command? It's called !Ay Caramba!.

MER Driver: I'm testing it right now

Flight Dir: Uh... ok I guess

20 minutes later

MER Driver: Mmmm... that can't be good

Flight Dir: If somebody calls for me, I'll be in my office working on my resume.

Working hard to get out of the sand. This the last update by Squyres.

Opportunity on the move! Later today JPL hoped to have straightened the wheels ready for a 2m drive out on Thursday (12 May), then rest for a week before attempting further drives.

The drive on Thursday will be back along the way Opportunity came into the drift.

They're being more cautious than they originally told me - taking more time over this critical operation.

Finally some movements!!! The wheels are in a different position after all that preparation. I'm not sure of the results so far. The back wheels are now completely underground. See those before and after shots.

Growing up in northern countries, I'm familiar with vehicles being stuck in snow. When trying to get unstuck, the results of first the first few moves, may seems worst than the original problem. But it's hopefully just an adjustment before the BIG backtracking moves.

On a more positive note: The front wheels looks much better and I think two things will come out from this first attempt: First the results (if this situation was predicted) are now confirming the properties of the sand (material) around the rover. Second, they probably learned a great deal from this and the next move will be much more effective.

We have begun the extraction process at Meridiani. So far we've executed three sols worth of activity. On the first one we simply straightened the wheels, which worked fine. The next two sols were executed over the weekend, and each commanded two meters worth of wheel turns. We were pleased with the outcome of those, too. The rover moved more than a centimeter in the expected direction during each maneuver, which was just the kind of behavior we were hoping for. (In fact, the motion was actually more than I was personally expecting to see this early in the game.) We clearly moved some soil in the process, and there was an encouraging amount of clearing of caked-up debris from between cleats on some of the wheels.

If you 'string' together some of the latest images released on the JPL site of the Opportunity wheels you can see a mini-movie of the wiggle-waggle of the wheel as it straightens out.

Slow steady progress -if only a few centimetres. But I understand they were going try a 4 m drive on sol 466.

Well this was the situation at sol 463; also check this gif.

Fingers crossed and let's hope JPL MER drivers have some golf-cart experience.

Opportunity Mars Exploration Rover de-trenched after 38 sols of carefully planning and manoeuvring... All six wheels on firm Martian soil on sol 484! Congrats to the JPL MER-team!!!

Yep - that's good news for JPL .

Its good news for future rover designers since many lessons learned from this episode

This is great news! In my opinion it would have been a great news story for the networks... but I guess they'd rather tell us about Michael Jackson and Britney Spears.

Hats off to JPL. Incredible machines. I wish they'd put one on the Moon, maybe land it at the impact sight of the Eagle's ascent stage and then head for the Apollo 11 landing sight. MAYBE, that would make news coverage.

NASA has given Indian names to certain types of rocks on Mars.
NASA has given Indian names to a number of rocks. We shall disclose the names soon after NASA gives a clearance to make this classified information public," NASA planetary geologist Amitabha Ghosh, currently on a three-city tour to India said on 13th June 2005.

You know we're doomed when NASA is outsourcing "rock naming" to India.

This is the Flight Director's Report: Today Spirit is finishing a remote sensing on a rock called Rama-Naresh-Rajan-Vajrang-Manish-kumar...

And why exactly would the names of Mars rocks be classified? Embargoed pending approval, I can understand, but classified?

I wondered the same as David - its probably more an embargo on news information - since they may have wanted Indian organisations that they are visiting be the first to know? Just a thought.

It may also be a 'carrot' for possible co-operation on future NASA unmanned Mars missions with India supplying experiments?

This is a very good movie (quicktime) of Opportunity 'bulldozing' its way out of the 'sand trap'

Looking at the latest images of tracks left by Opportunity, it seems to be in another area of dune ridges where the wheels are sinking to a sizeable depth in the 'sand'.

Beautiful image! The best dust devil pic yet IMO.

BTW, it's been almost a month since any Rover press images were released.

I guess NASA's been busy with the Shuttle, but I sure did enjoy the press images releases.

They actually release new images (press images with captions, not raw) nearly every day. They just don't promote them much anymore.

Bookmark this site and check back daily for the new ones from MER and all the JPL missions

Cool! Thanks for the link Ben. I've been kind of frustrated myself with the lack of intersting updates on the MER page.

On the same topic, I had chance to attend a book signing by Steve Squyres last week at the local library. Steve gave a talk with a really good slideshow where he even had some very recent images from just the day before. He is a great speaker and hops around in front very excited about the images and it's easy to see that he loves his work. Very entertaining guy to listen to, and the question/answer time afterwards went on for about 45 minutes after. The talk was acutally for a local Cornell Univerity Alumni group, but I got told about it from a friend that works at the library since it wasn't a public event.

I wish I could find a job that I could get that excited about. *sigh*

Amazing dust-devil picture. Hard to believe it's happening in a near-vacuum.

Does anyone have the facilities to re-post the picture with the contrast enhanced to show greater detail in the dust vortex visible against the bright sky?

Impress us!

The ol' girl's made it - and the views are superb,spectacular and are probably some of the best space images we have seen since 1957 started it all !

You need to visit JPL's Mars MER site for Spirit images.

Some of the panoramas from Spirit sat atop Husband Hill on MArs are really fantastic.

They make good desktop images and a printed panorama will sit very nice on the wall.

Phill,

Do you have the new summit pics link handy? I looked and looked this morning at home and I couldn't find the summit images via this page. Is it a different page?

BTW, everyone, the new dust devil movies are not to be missed. Watch them all here.

There's even one Hazcam movie where a dust devil goes right over the rover!

There are several images - which can be stitched together - in the pncam section for latest sols.
