As such, the rover only turned to face the future destination and bumped 4 inches 10 centimeters. Opportunity encountered an undisturbed collection of putative Martian dust, collecting in a small ripple field. On Sol Oct. Opportunity is ascending the northern edge of 'Solander Point' at the rim of 'Endeavour Crater. On the following sol, the rover continued driving with a nearly 33 feet meter drive toward another energy lily pad.
As of Sol Oct. Opportunity also fit in after the drive an atmospheric argon measurement with the APXS. Opportunity is ascending the northern edge of 'Solander Point' at the rim of Endeavour Crater. The rover is maintaining favorable northerly tilts for improved energy production as winter approaches. After completing a few sols of remote sensing, the rover headed south on Sol Oct.
On the next sol, a bump of 24 inches 60 centimeters was performed to put the surface science targets within reach of the rover's robotic arm. Opportunity is on the northern edge of 'Solander Point' at the rim of Endeavour Crater.
The rover is investigating the geologic contacts at the base of Solander Point. Opportunity is at the northern edge of 'Solander Point' on the rim of Endeavour Crater. The rover is investigating the geologic contact at the base of Solander Point. On Sol Sept. In the process the rover collected some Panoramic Camera Pancam color imagery of a ripple and completed a post-drive Navigation Camera Navcam panorama.
As of Sol Sept. Sol Sept. A short, 7 foot 2-meter bump followed, set the rover in position for some in-situ contact science on a surface target. A foot At the beginning of the drive, Opportunity looked back at target 'Wally Wombat' to acquire a filter Pancam image of the brushed target. On the next sol, the rover deployed the robotic arm to investigate the surface target named, 'Poverty Bush.
Then, the rover collected some calibration sky flat images with the Microscopic Imager MI. On the next sol, the rover continued driving another 74 feet Opportunity is at the base of 'Solander Point' on the rim of Endeavour Crater. The rover is investigating the geologic contact at the edge of Solander Point.
A seven-frame Navigation Navcam Camera panorama was also collected. The rover is investigating a scarp rock outcrop , called 'Coal Island. The rover began a survey of the scarp with multi-spectral Panoramic Camera Pancam imaging.
Opportunity continued the multi-spectral imaging survey of the scarp with more Pancam images over three sols. The rover is navigating around a large boulder field examining the geologic contacts in this area. On Sol Aug. Navigation Camera images of the rover tracks were also collected. On the following sol, the rover collected a measurement of atmospheric argon using the Alpha Particle X-ray Spectrometer. As of Sol Aug.
The rover is scouting a large boulder field. After remote sensing observations over the weekend, on Sol Aug. The rover is positioned in front of a large rock, called 'Tick Bush' for in-situ contact investigation with the instruments on the robotic arm.
Also on that sol, the rover took advantage of a celestial alignment and imaged the transit of both moons, Phobos and Deimos. A second Phobos transit was imaged on the next sol while the APXS continued to integrate on the rock target. The rover arrived at the edge of Solander Point with a series of drives on Sols and Aug.
Later, the rover will drive up onto the point and benefit from the north-facing slope there. Taking advantage of a surface target of opportunity within the robotic arm work volume, the rover performed two-sol 'Touch 'n Go' on Sols and Aug. On the first sol, Opportunity used the robotic arm to collect a Microscopic Imager mosaic of the surface target called 'Red Poker' and then place the Alpha Particle X-ray Spectrometer on the target for an overnight integration. On the second sol, the rover drove away, moving 15 feet 4.
Opportunity has been investigating an in-situ contact science target, a rock called 'Black Shoulder. On the morning of the second sol, the first set of Panoramic Camera Pancam images of Solander Point, as part of a long baseline stereo imaging campaign, were collected. With the work now complete at Black Shoulder, the rover drove about 33 feet 10 meters to the east on Sol July 31, , to set up for the second set of Pancam images of Solander Point, part of the long baseline stereo imaging campaign.
As of Sol July 31, , the solar array energy production was watt-hours with an atmospheric opacity Tau of 0.
Opportunity has arrived in the region near the base of 'Solander Point. However, the science team will now begin the exploration of the various outcrops, contacts and units that make up the Solander Point geology, prior to ascending the point for winter energy production. On Sol July 18, , the rover advanced about feet 60 meters towards a region to the northeast of Solander Point to investigate the unusual terrain there. Sols and July 20 and 21, , were a 2-sol Touch 'n Go activity.
The rover performed robotic arm in-situ contact science with the Microscopic Imager MI and the Alpha Particle X-ray Spectrometer APXS on the first sol, then picked up and drove over feet 50 meters on the second sol.
On Sol July 23, , Opportunity bumped 12 feet 3. Before the drive on Sol , the rover took the opportunity to image a Deimos moon transit of the Sun with the Panoramic Camera. As of Sol July 23, , the solar array energy production was watt-hours with an atmospheric opacity Tau of 0.
Opportunity is in good health. We are now within a few hundred feet, or meters of the 'Solander Point' destination.
However, the team doesn't need the northerly tilt that Solander Point offers yet, so they decided to use a few of the margin sols accumulated to investigate an area of interesting terrain and gypsum signatures. The Sol July 13, drive began veering to the Southeast and then to the East in the Sol July 16, drive. The team sequenced a multi-sol drive in the three-sol plan of July July 15, However, though the first sol drive of feet 80 meters on July 13, completed nominally, the second sol drive on Sol July 14, , was precluded due to exceeding a pitch-limit at the end of the first sol of driving.
This was as a result of a safety check specifically designed for multi-sol drives, which worked as intended as Opportunity happened to find herself in a shallow depression at the end of Sol July 13, drive. In total, Opportunity drove feet meters in three drives for this period. As of Sol July 16, , the solar array energy production was watt-hours with an atmospheric opacity Tau of 0. On Sol June 27, , the rover drove over feet over meters , heading toward 'Solander Point' on the rim of Endeavour Crater.
Also on that sol, a set of diagnostics were performed on the Joint 3 elbow potentiometer on the robotic arm. This potentiometer is a sensor that can indicate if the arm has moved. Arm movement is not intended during a drive. Preliminary analysis indicates that the readings from the potentiometer were anomalous and that the arm did not move.
The project is masking those readings in the rover's flight software so that anomalous readings will not halt a drive. In a two-sol plan, Opportunity performed a 'touch 'n go,' using the robotic arm one sol and driving the next sol, on Sols and , June 28 and June 30, , using the Pacific Daylight Time date at noon of the sol; no sol's noon fell on June On the first sol, the Microscopic Imager MI collected a mosaic of a surface target.
On the second sol of the plan, the rover drove over 98 feet over 30 meters. On Sol July 2, , Opportunity completed another long drive, over feet over meters. In preparation for the long Fourth of July holiday period, two sets of three-sol plans were developed to keep Opportunity busy while the flight team had time off.
The first plan covered sols to July 3 to July 5, A foot meter drive was sequenced for the first sol, with a special automatic stop to use rover tilt and achieve maximum power generation for later activities. It conducted routine remote-sensing measurements on the third sol. With the drive results from Sol July 3, received in time for planning the next three-sol plan, the flight team sequenced another drive for Sol July 7, after a special observation of both of Mars' moons.
Opportunity imaged Phobos and Deimos with the Panoramic Camera Pancam very early on the morning of that sol, using that extra energy from the rover's favorable tilt. After the observation finished, the rover drove feet 42 meters. It spent the final sol of this three-sol plan recharging batteries with some light remote-sensing observations.
After the holiday, Opportunity continued to push closer to Solander Point with a drive on Sol July 9, that exceeded feet As of Sol July 10, , the solar array energy production is watt-hours with an atmospheric opacity Tau of 0. Opportunity is in good health, although the robotic arm elbow joint potentiometer is acting up. On Sol June 22, , the rover continued the trek toward 'Solander Point' with a foot meter drive due south. On the next sol, Opportunity exceeded 23 miles 37 kilometers of odometry with a feet meter drive.
On Sol June 25, , a long drive was planned, but was terminated after only feet 63 meters when the potentiometer on the robotic arm elbow indicated an unexpected motion, stopping the drive. This potentiometer is a sensor that can indicate if the arm has moved, which is not intended during a drive. Investigation of the joint and the use of before and after images showed no joint motion. A drive was planned on Sol June 26, , and stopped almost immediately due to an even larger anomalous reading of that same potentiometer.
The plan ahead is to conduct a set of diagnostics on the joint potentiometer. As of Sol June 26, , the solar array energy production was watt-hours with an atmospheric opacity Tau of 0. As of June 21, , Opportunity has been on Mars for five Martian years. The project successfully recovered the rover from the flash-memory write error induced reset on Sol June 12, , which left the rover without a running master sequence.
The initial recovery attempt on Sol June 13, , was not successful because the rover did not wake earlier enough to receive the recovery commands, although it was understood that this was a possibility due to variability in the morning wake-up time.
Opportunity was successfully recovered over Sols and June 14 and 15, The second sol also included a foot meter drive. That drive contained the first part of a two-sol test of multi-sol autonomous driving. The rover drove again on Sol June 18, , with a foot meter drive which contained the second part of the multi-sol autonomous driving. On Sol June 20, , the science team decided to head east toward the feature called 'Nobbys Head' for a closer look with the rover driving just under feet 33 meters.
The plan ahead is to turn south and make a direct beeline to 'Solander Point' still over a kilometer away. As of Sol June 20, , the solar array energy production was watt-hours with an atmospheric opacity Tau of 0. Opportunity is continuing her push to reach 'Solander Point,' still over 1. The rover drove only two of the last seven days sols due to the long holiday weekend. Opportunity drove on Sols and May 23 and May 29, , totaling feet meters , continuing in the southeasterly direction.
The plan ahead is more driving as the rover moves towards Solander Point. As of Sol May 29, , the solar array energy production was watt-hours with an atmospheric opacity Tau of 0. Opportunity has begun the departure from 'Cape York' and started the push to reach 'Solander Point' over 1. The rover drove five out of the last seven days sols. Opportunity drove on Sols , , , and May 16, 18, 20, 21 and May 22, , totaling over 0.
Atmospheric opacity tau has been decreasing after it spiked from the passing of a regional dust storm. Opportunity benefitted from a modest solar array dust cleaning event between Sol and May 17 and 21, The plan ahead is more to drive as the rover pushes towards Solander Point.
As of Sol May 22, , the solar array energy production was watt-hours with an atmospheric opacity Tau of 0. Opportunity has set a new off-world driving record for a U. Early analysis seems to confirm that this is a clay that had been intensely altered by relatively neutral pH water - representing the most favorable conditions for biology that Opportunity has yet seen in the rock histories it has encountered. A local dust storm had cause us some concern as we saw the atmospheric opacity tau increase to the neighborhood of 1.
Solar array energy on Sol May 15, , was watt-hours with an atmospheric opacity Tau measurement of 1. All systems are nominal. Opportunity is feverishly working to complete analysis of 'Esperance,' believed to be a phyllosilicate-rich target, before departing for her winter haven at 'Solander Point' to the south. Complicating the satisfactory completion of the rock Esperance analysis was the growth of a regional dust storm nearby, which drove the atmospheric opacity or tau to 1.
The tau on Sol May 8, , slightly decreased to 1. If atmospheric opacity stabilizes or continues to decrease, we hope to complete instrument deployment device IDD work and begin driving away by Sol May 15, Maintaining Favorable Tilt for Sunshine.
