MER-2 "Opportunity"

[X]

Sol-by-sol summaries:

Sol 467 (May 17):
Opportunity was commanded to rotate its wheels enough to have rolled 4 meters (13 feet) if there were no slippage. It advanced 2.1 centimeters (0.8 inch) through the loose material of the dune.

Sol 468:
A commanded motion of 8 meters (26 feet) was executed this sol. Forward progress was about 4 centimeters (1.6 inches).

Sol 469:
A 2-meter (7-foot) drive was commanded, and Opportunity advanced about 1 centimeter (0.4 inch).

Sol 470 (May 20):
The rover was sent commands for a 12-meter (39-foot) drive. This drive incorporates larger step sizes, lower current limits for the drive motors, and a lower bogie angle limit.

"If Opportunity gets free, its next task will be examining the site to give the rover team a better understanding of how this ripple differs from dozens Opportunity easily crossed," said Jim Erickson. He is project manager for the Mars Exploration Rover Project at NASA's Jet Propulsion Laboratory, Pasadena, Calif.



The rover has moved about 10 inches (27 centimeters) – though its wheels turned enough to travel 157 feet (48 meters) – which mission controllers say is good progress.


"We're only traveling about half a percent of what we're commanding," explained Jim Erickson, rover project manager at NASA's Jet Propulsion Laboratory. "So it's a very low number, but very consistent."

At the current rate, it may be two more weeks before Opportunity once again reaches safe ground, Erickson added.

We're out! The Sol 484 downlink from Opportunity just hit the ground, and all six wheels are on top of soil. More later when I've got some details, but I wanted to get the news out now while it's hot. We've been confident all along that this would happen but still... what a relief!

Хм, а тут фотки пока только за 483 sol, тут даже одно колесо совсем под песком скрылось :\

Sol 476 (beginning on May 26, 2005): 12 meters (39 feet) commanded, 5.5 centimeters (2.2 inches) progress.

Sol 477: 12 meters (39 feet) commanded, 11.2 meters (37 feet) executed, 4.9 centimeters (2 inches) progress. (Visual odometry indicated that the rover had gone farther than it had, and flight software stopped the drive early.)

Sol 478: 12 meters (39 feet) commanded, 5.2 meters (17 feet) executed (due to the same issue with visual odometry), 2.2 centimeters (0.9 inch) progress.

Sol 479: 12 meters (39 feet) commanded and executed, 5.9 centimeters (2.3 inches) progress.

Sol 480: 12 meters (39 feet) commanded and executed, 6.3 centimeters (2.5 inches) progress.

Sol 481: 20 meters (66 feet) commanded and executed, 12.9 centimeters (5.1 inches) progress.

Sol 482: 20 meters (66 feet) commanded and executed, 10.7 centimeters (4.2 inches) progress.

Sol 483 (ending on June 3, 2005): 20 meters (66 feet) commanded and executed, about 13 centimeters (5.1 inches) progress.



Since the rover began making its way out of the sand trap last month, it has driven enough to have moved 177.2 meters (581 feet) if there were no slippage, and has made actual forward progress of 93 centimeters (3 feet).

We're out! The Sol 484 downlink from Opportunity just hit the ground, and all six wheels are on top of soil.

...it's hard to describe how good it felt to check out the downlink this morning and see all six wheels back on solid ground again.

Скажите, а поворот колёс то работает или нет? Это он отказал или просто не работал оттого что колесо зарылось?

So what comes next? The first thing we're going to do is simply take a very hard look at the stuff we were stuck in. Much of the worst terrain was under the belly of the rover through all of this, down where we couldn't see it. From our new position, everything that was under us for all those weeks is now visible. So we're going to take a little while just to look at where we were. We may also turn to take a look at our tracks (or trenches, or whatever you want to call them) with some of the instruments on the arm.  

After that -- and there is no timetable for any of this -- we will begin a cautious set of moves to get us on our way again. And just so there's no doubt about it, this little incident is not going to deter us from continuing our southward exploration. South is where we think the best science is, and we're not going to turn tail and run because of one unfortunate episode. Now if we find after continued driving that the southward road is simply impossible, then it'll be time to start thinking about something else. But for now, south is where we plan to go.

The robot is now about 1,300 feet from its next probable target known as Erebus crater - a formation quite a bit larger than earlier impact sites visited.
