sol 1051-1057, December 22, 2006: Spirit Tests New Computer Smarts, Studies Rocks and Terrain

Spirit is healthy and conducting scientific analysis of a rock target known as "Palma." During the past week, Spirit tested some new software sequences, including a "watch for dust devil" command and an automatic placement command.

On the rover's 1052nd Martian day, or sol, of exploring Mars (Dec. 18, 2006), Spirit ran part of the dust devil watch, acquiring six images during the process, but did not run the dust-devil detection part of the program. Rover handlers planned to rerun the test on sol 1058 (Dec. 24, 2006).

On sol 1053 (Dec. 19, 2006), Spirit terminated a test run of a command sequence for autonomous placement of the rover's robotic arm on a scientific target. The sequence involved touching a target with the Mössbauer spectrometer, changing tools to the microscopic imager and suspending it 10 centimeters (4 inches) above the target, changing tools to the alpha-particle X-ray spectrometer, and placing the alpha-particle X-ray spectrometer on the target. Spirit made preparations to run the test again on a new target on the same day that some Earthlings celebrate as Christmas Eve.

Sol-by-sol summary:

Sol 1051 (Dec. 17, 2006): Spirit turned to face a rock outcrop known as "Esperanza," acquired images with the hazard avoidance cameras and a 360-degree panorama with the panoramic camera, and scanned the sky for clouds with the navigation camera. The rover measured atmospheric dust, looked at the sky, examined the terrain, and completed a survey of individual rock grains, known as clasts, using the panoramic camera.

Sol 1052: Spirit conducted step No. 2 of the new capability to watch for dust devils and scanned the sky for clouds with the navigation camera.

Sol 1053: Spirit acquired microscopic images of Palma, conducted step No. 2 of the autonomous placement test, monitored dust in the atmosphere with the panoramic camera, scanned the sky and ground with the miniature thermal emission spectrometer, scanned the sky for clouds with the navigation camera, and monitored the rover mast for dust accumulation.

Sol 1054: Spirit scanned the sky and ground with the miniature thermal emission spectrometer and collected miniature thermal emission spectrometer data from a ground target known as "Melchior." The rover continued to measure atmospheric dust opacity and take images of the sky with the panoramic camera.

Sol 1055 (Dec. 21, 2006): Because the rover was not stationed at the appropriate distance from the target for the automatic placement test, Spirit prepared to run the test with the alpha-particle X-ray spectrometer a second time, followed by six hours of measurement with the instrument. Spirit was slated to scan the sky, ground, and a target known as "Druzhnaya" using the miniature thermal emission spectrometer as well as acquire frames for a dust devil movie.

Sol 1056: Plans called for four hours of analysis of Palma using the Mössbauer spectrometer, measurements of atmospheric dust with the panoramic camera, a check for changes over time in the miniature thermal emission spectrometer, and a scan of the ground and sky at various elevations using the miniature thermal emission spectrometer. Spirit was also to acquire panoramic camera and stereo images of a rock nicknamed "Orcadas."

Sol 1057 (Dec. 23, 2006): Plans called for Spirit to conduct an additional 3.5 hours of study of Palma using the Mössbauer spectrometer, measure atmospheric dust with the panoramic camera, check for drift (changes in time) in the miniature thermal emission spectrometer, scan the sky and ground with the miniature thermal emission spectrometer, check the calibration target of the same instrument, and use it to scan a rock target known as "Gueslaga."

Odometry:

As of sol 1054 (Dec. 20, 2006), Spirit's total odometry was 6,886.80 meters (4.28 miles).


sol 1043-1050, December 18, 2006: Relay Link Restored After Orbiter's Recovery

After Spirit drove on sol 1041 (Dec. 7, 2006), NASA's Mars Odyssey orbiter went into safe mode before the rover's could relay data to Earth about results of the drive. (Safe mode is a protective state during which only the systems essential to spacecraft health continue operating. This incident of Odyssey temporarily going into safe mode has been attributed to a burst of solar activity.) Since the rover team didn't have current information about Spirit's position and state, the rover spent eight successive Martian days, or sols, collecting untargeted remote sensing data.

Data transmission directly to Earth from Spirit on sol 1046 (Dec. 12, 2006) confirmed that Spirit was healthy. Odyssey recovered the following day and resumed relaying data from Spirit, transmitted from the rover to the orbiter in the UHF radio band.

Sol-by-sol summary:

Sol 1043 (Dec. 9, 2006): Spirit surveyed the rover's tracks using the miniature thermal emission spectrometer and measured atmospheric dust opacity with the panoramic camera. The rover surveyed the sky and ground with the miniature thermal emission spectrometer.

Sol 1044: Spirit surveyed the area where the rover spent the past Martian winter with the miniature thermal emission spectrometer and took panoramic camera images of the area.

Sol 1045: Spirit took thumbnail images of the sky with the panoramic camera and scanned the sky for clouds with the navigation camera. Spirit monitored the rover mast for dust and relayed the first bits of scientific data collected and stored on sol 1040 (Dec. 6, 2006).

Sol 1046: Spirit surveyed the rover's winter haven with the miniature thermal emission spectrometer and monitored atmospheric dust with the panoramic camera. The rover scanned the sky and ground with the miniature thermal emission spectrometer.

Sol 1047: Spirit collected miniature thermal emission spectrometer data from a soil target known as "Tyrone" and continued acquiring panoramic camera images of the rover's winter haven.

Sol 1048: Spirit acquired thumbnail images of the sky with the panoramic camera and scanned the sky for clouds with the navigation camera. The rover monitored atmospheric dust with the panoramic camera, and surveyed the sky, ground, and calibration target with the miniature thermal emission spectrometer.

Sol 1049: Spirit acquired navigation camera images in support of miniature thermal emission spectrometer measurements of the rover's surroundings. The rover monitored atmospheric dust with the panoramic camera and acquired panoramic images of the area ahead.

Sol 1050 (Dec. 16, 2006): Spirit's instructions call for scanning for clouds and dust devils with the navigation camera, surveying the mast for dust accumulation and observing the sky and ground with the miniature thermal emission spectrometer.

Odometry:

As of sol 1048 (Dec. 14, 2006), Spirit's total odometry was 6,885.62 meters meters (4.28 miles).


sol 1039-1042, December 08, 2006: Spirit Slowly Resumes Driving on Martian Terrain

Despite a non-functioning right front wheel, Spirit is healthy and on the move. The rover completed short drives on Martian days, or sols, 1039 (Dec. 5, 2006) and 1041 (Dec. 7, 2006) on its way toward a rock target informally named "Esperanza."

Sol-by-sol summary:

Sol 1039 (Dec. 5, 2006): Spirit drove 1 meter (3.3 feet) and acquired images after the drive using the hazard avoidance and navigation cameras. The rover took a super-resolution image with the panoramic camera and scanned the Martian sky for clouds with the navigation camera.

Sol 1040: Spirit scanned the sky, ground, and Esperanza using the miniature thermal emission spectrometer. The rover surveyed the sky and the horizon with the panoramic camera.

Sol 1041: Spirit turned in the direction of Esperanza, then drove another 1.5 meters (5 feet) toward the rock. Spirit acquired more detailed images after the drive with the hazard avoidance camera and a 360-degree view of the rover's surroundings with the navigation camera. The rover searched the sky for clouds with the navigation camera and took panoramic images of the "El Dorado" dune field and the Martian sky.

Sol 1042 (Dec. 8, 2006): Spirit panoramic camera took images for a full-color, 13-filter mosaic of the area studied by the rover during the last Martian winter. Spirit also scanned the area with the miniature thermal emission spectrometer.

Odometry:

As of sol 1039 (Dec. 5, 2006), Spirit's total odometry was 6,880.86 meters (4.28 miles).


sol 1024-1038, December 05, 2006: Spirit Slowly Begins Driving Again

Spirit is healthy and preparing to drive away from the rover's winter station after completing scientific investigation of a rock nicknamed "King George Island." The rock, according to principal investigator Steve Squyres, contains some of the best-rounded grains ever seen in a Martian rock. Scientists will try to determine how the grains formed -- perhaps with help from wind or water.

Spirit arrived at King George Island on Sol 1022 (Dec. 17, 2006) after a short bump (very short drive) from a disturbed soil target nicknamed "Bear Island." Upon arrival, Spirit took a mosaic of microscopic images of King George and collected data using the alpha-particle X-ray and Mössbauer spectrometers. Spirit then brushed the target with the wire bristles on the rock abrasion tool before collecting more alpha-particle X-ray and Mössbauer data for comparison with data from the unbrushed surface.

Spirit's next planned target is a rock aptly nicknamed "Esperanza," the Spanish word for hope. The first of several drives to reach that goal began on Sol 1037 (Dec. 3, 2006). On Sol 1030 (Nov. 25, 2006), the Mars Reconnaissance Orbiter used its high-resolution camera to acquire images of Spirit's "Winter Haven," where the rover has spent its second Martian winter, and of Spirit's lander, which arrived on Mars Jan. 4, 2004.

Sol-by-sol summaries:

In addition to Spirit's daily science observations, which include measuring atmospheric dust opacity with the panoramic camera, surveying the sky and ground using the miniature thermal emission spectrometer, and scanning the Martian sky for clouds using the navigation camera, the Mars rover did the following work:

Sol 1024 (Nov. 19, 2006): Spirit collected data about the Martian atmosphere using the alpha-particle X-ray spectrometer and monitored dust accumulation on the panoramic camera mast.

Sol 1025: Spirit acquired super-resolution panoramic camera images of the circular plateau-like feature known as "Home Plate" and measured the amount of light detectable at night and during Martian twilight.

Sol 1026: Spirit coordinated daily science observations with an overflight of the Mars Reconnaissance Orbiter. The rover measured surface reflectivity using the panoramic camera.

Sol 1027: Spirit acquired a mosaic of images of King George Island and collected data from the same rock target using the alpha-particle X-ray spectrometer.

Sol 1028: Spirit studied King George Island using the Mössbauer spectrometer.

Sol 1029: Spirit studied Esperanza and two other rock targets known as "Zhong Shan" and "Korolev" using the miniature thermal emission spectrometer.

Sol 1030: Spirit continued to assess King George Island using the Mössbauer spectrometer and investigated a distant rock outcrop known as "Oberth" using the miniature thermal emission spectrometer.

Sol 1031: Spirit brushed the surface of King George Island using the rock abrasion tool and acquired microscopic images and alpha-particle X-ray data of the freshly brushed surface.

Sol 1032: Spirit acquired Mössbauer data from the brushed surface of King George Island.

Sol 1033: Spirit acquired information about rock targets known as "Syowa" and "Wiltgen" using the miniature thermal emission spectrometer.

Sol 1034: Spirit collected microscopic images of two soil targets known as "Clarence" and "Deception" and recommenced analysis of the brushed surface of King George Island using the Mössbauer spectrometer.

Sol 1035: Spirit analyzed a spot on the same rock surface but offset from the target known as King George Island by acquiring microscopic images and collecting corresponding compositional data with the alpha particle X-ray spectrometer.

Sol 1036: Spirit acquired a 13-filter, full-color panorama of the soil target known as "Tyrone" and again analyzed Korolev and Esperanza from a distance using the miniature thermal emission spectrometer.

Sol 1037: Spirit stowed the robotic arm carrying scientific instruments and began driving toward Esperanza.

Sol 1038 (Dec. 4, 2006): Spirit tested new capabilities for automated placement of the robotic arm.

Odometry:

As of sol 1036 (Dec. 2, 2006), Spirit's total odometry was 6,877.63 meters (4.27 miles).


sol 1017-1023, December 04, 2006: More Remote Science for Spirit

Spirit is healthy. Downlink of information from the rover resumed after a 48-hour gap in downlink that resulted from NASA's Mars Odyssey releasing most of its Deep Space Network coverage earlier in the week to Mars Global Surveyor to support efforts to recover communications with Global Surveyor.

This week, Spirit changed robotic-arm targets from "Berkner Island" to "Bear Island" and executed a microscopic image mosaic, five hours of data collection with the alpha particle X-ray spectrometer and nearly 48 hours with the Mössbauer spectrometer. The engineering team planned and commanded Spirit's second drive of the season on sol 1022.

Sol-by-sol summaries:

Sol 1017 (Nov. 12, 2006): Spirit used its microscopic imager to take exposures for a stereo mosaic of target Bear Island, then placed the alpha particle X-ray spectrometer on that target. After the Mars Odyssey pass, the rover took a tau (atmospheric clarity) measurement and then began a five-hour reading with the alpha particle X-ray spectrometer.

Sol 1018: The panoramic camera took thumbnail images of the sky, and the navigation camera scanned for clouds. The team changed tools to the Mössbauer spectrometer and used it for a 10-hour integration on Bear Island.

Sol 1019: In the morning, the miniature thermal emission spectrometer assessed the sky and ground, and the panoramic camera examined the sky. The miniature thermal emission spectrometer then stared at target "Baudoin." Some engineering maintenance was done and then the Mössbauer spectrometer was restarted on target Bear Island.

Sol 1020: In the morning, the miniature thermal emission spectrometer assessed the sky and ground, and the panoramic camera examined the sky. The rover restarted the Mössbauer data-collection on Bear Island for a 23-hour, overnight integration.

Sol 1021: Spirit's miniature thermal emission spectrometer assessed light-toned material in the rover's tracks in the morning. The Mössbauer spectrometer was restarted on Bear Island. The panoramic camera conducted a light experiment by taking multiple images throughout the day. The miniature thermal emission spectrometer assessed target "Allan Hills" during the communications pass with Mars Odyssey. After the Odyssey pass, the Mössbauer observation was completed and the panoramic camera took a tau measurement at sunset.

Sol 1022: Spirit's arm was stowed before the rover began a short drive to a nearby outcrop. After the drive the navigation and hazard avoidance cameras took images. A tau measurement was taken as well.

Sol 1023 (Nov. 28): The panoramic camera took images of targets "El Dorado" and "Prat" as well as thumbnail images of the sky. The miniature thermal emission spectrometer conducted a sky and ground observation.

Odometry:

As of sol 1023, Spirit's odometry is 6,877.63 meters (4.27 miles).


sol 1013-1016, November 13, 2006: Spirit's 'Arm' Busy Checking New Targets

After Spirit's successful 0.71-meter (28-inch) bump on sol 1010, the team has new targets in the robotic arm's work volume for the first time in 204 sols. There is some interesting light and dark material within arm's reach and this week the team planned a robotic arm campaign including a microscopic imager mosaic, four hours of alpha particle X-ray spectrometer integration and 43 hours of Mössbauer spectrometer integration. Spirit is receiving a little over 320 Watt-hours now and is able to occasionally use the Mössbauer or alpha particle X-ray spectrometer overnight.

Sol-by-sol summary:

Sol 1013 (Nov. 8, 2006): This sol began with the usual engineering block tau (atmospheric clarity) measurement, then a calibration of the miniature thermal emission spectrometer before that instrument was used to stare at the sky and ground. Spirit then used its front hazard avoidance cameras to look at the robotic arm's work volume, then unstowed the arm and took a stereo microscopic image of target "Berkner Island." The rover then placed the alpha particle X-ray spectrometer on Berkner Island and integrated for four hours. Spirit used its miniature thermal emission spectrometer to stare at target "Davis" during the afternoon when NASA's Mars Odyssey spacecraft passed overhead.

Sol 1014: The rover changed tools to the Mössbauer spectrometer and integrated for 23 hours.

Sol 1015: During the morning of this sol, Spirit conducted dust monitoring of its panoramic camera mast assembly (its neck and head). The rover then restarted the Mössbauer on target Berkner Island for a 10-hour integration. A panoramic camera tau measurement and a miniature thermal emission spectrometer observation of sky and ground were conducted around the Odyssey pass.

Sol 1016: On this sol, Spirit took images with its navigation camera. It then restarted the Mössbauer spectrometer on Berkner Island for a 10-hour integration. Total integration time is 43 hours at this target. The rover then conducted a panoramic camera sky observation.

Odometry:

As of sol 1016 (Nov. 11, 2006), Spirit's odometry is 6,876.89 meters (4.27 miles).



sol 1006-1012, November 07, 2006: Spirit Passes 1000 Sols and Continues its Winter Campaign

Spirit is healthy and is starting to stir from its winter resting spot.

Sols 1006 through 1009 were spent working on winter campaign observations; Spirit is entering the final phase of these observations.

Sol 1010 saw Spirit stir from its winter resting spot with a 33-degree turn and a 0.71-meter (28-inch) bump. This was done so that Spirit could reach the bright soil pushed up by its right front wheel when the rover arrived here about 200 sols ago.

On Sol 1011 Spirit performed a coordinated experiment with NASA's Mars Reconnaissance Orbiter. This test was performed to characterize performance of the orbiter's UHF Electra radio. Mars Reconnaissance Orbiter will provide data relay services for NASA's Phoenix Mars Lander, which is scheduled to arrive at Mars in May 2008.

Sol-by-sol summary:

Sol 1006 (Nov. 1, 2006): Spirit assessed atmospheric clarity (a "tau" measurement) with its panoramic camera, calibrated its miniature thermal emission spectrometer and then used that instrument to stare at the sky and ground. The rover's microscopic imager was used to image the rover's magnet array and a solar panel. During the communication window with NASA's Mars Odyssey, the rover again used the miniature thermal emission spectrometer to look at the sky and ground. After the Odyssey pass, the panoramic camera imaged the sunset.

Sol 1007: In the morning of this sol, Spirit's miniature thermal emission spectrometer measured a dust spot. A tau measurement was taken by the panoramic camera and the miniature thermal emission spectrometer checked out the sky and ground. The microscopic imager took images for stereo mosaics and the miniature thermal emission spectrometer was calibrated.

Sol 1008: This morning Spirit used its navigation camera to look for clouds and then used its miniature thermal emission spectrometer to look at the sky and ground. The rover then used its panoramic camera to do a tau measurement before the miniature thermal emission spectrometer was used again. The microscopic imager was then used on targets "Palmer" and "Mawson." The arm was stowed and then the panoramic camera did a light check before it imaged the sunset.

Sol 1009: Spirit used its navigation camera this morning to look for clouds and then took thumbnail images of the sky with its panoramic camera. The panoramic camera also surveyed the horizon. The miniature thermal emission spectrometer completed a sky and ground observation before the Odyssey pass. During the communication window with Odyssey, the spectrometer stared at target "Casey Station." After the Odyssey pass the rover did a tau measurement with the panoramic camera and began to use the alpha particle X-ray spectrometer on "Argon."

Sol 1010: During the morning of this sol, Spirit used its panoramic camera to image "El Dorado." The hazard avoidance cameras were aimed at some fine ripples to assess them. The miniature thermal emission spectrometer stared at some Martian dust and the panoramic camera assessed the atmosphere. Again, the miniature thermal emission spectrometer was used to stare at the sky and ground. The rover was commanded to do a "bump," or very short movement. Post-bump images were taken with the navigation camera and the hazard avoidance cameras.

Sol 1011: Spirit used its panoramic camera to have a look at the sky before it began to take a large panoramic image. The miniature thermal emission spectrometer was used to look at the sky and ground before Spirit interacted with its Martian partner overhead, the Mars Reconnaissance Orbiter.

Sol 1012 (Nov. 7, 2006): On this sol, the panoramic camera was used to finish the panorama it began "yestersol." The panoramic camera took a tau measurement before the miniature thermal emission spectrometer had a look at the sky and ground.

Odometry:

As of sol 1010 (Nov. 5, 2006), Spirit's total odometry is 6,976.89 meters (4.34 miles).



sol 982-987, October 16, 2006: Approaching Solar Conjunction

As Spirit enters a period known as solar conjuction, when the sun interferes with transmissions between Mars and Earth, mission planners sent a complete set of plans for science activities during solar conjunction to Spirit on the rover's 982nd sol, or Martian day, of exploring inside Gusev Crater (Oct. 7, 2006). During that time, the rover will achieve a new milestone: exploring Mars for 1,000 consecutive days.

Solar conjunction will begin on sol 991 (Oct. 16, 2006) and end on sol 1015 (Nov. 10, 2006). During this period, both NASA rovers, Spirit and Opportunity, will not receive any new command loads, but they will send daily downlinks to Earth, averaging 15 megabits of data per transmission. The data will be relayed to Earth via NASA's Mars Odyssey spacecraft in orbit above Mars.

Each day during conjunction, Spirit will spend 3 hours analyzing dust collected on the rover's filter magnet using the Mössbauer spectrometer and 24 minutes conducting a variety of early morning science observations. The morning science activities are designed to monitor the atmosphere and to search for any possible surface changes. The workload will make optimum use of solar power levels available with the retreat of Martian winter.

Spirit is healthy and continues to make progress on the winter science campaign of experiments. The rover's solar energy levels continue to rise slowly. Solar power is currently about 300 watt-hours. One hundred watt-hours is the amount of electricity needed to light one 100-watt bulb for one hour.

Sol-by-sol summary:

Sol 982 (Oct. 7, 2006): Spirit measured atmospheric dust opacity with the panoramic camera and surveyed the sky, ground, and dark soil in the rover's tracks using the miniature thermal emission spectrometer. Spirit took panoramic camera images of the rover's tracks and analyzed rock targets known as "Gueslaga" and "Tor" with the miniature thermal emission spectrometer. The rover measured the brightness of the morning sky in the west using the panoramic camera.

Sol 983: Spirit measured atmospheric dust opacity with the panoramic camera and surveyed the sky, ground, and dark soil in the rover's tracks using the miniature thermal emission spectrometer. Spirit took a look at the elemental chemistry of the atmosphere with the alpha particle X-ray spectrometer. The rover acquired super-resolution panoramic camera images of a target called "Mitcheltree Ridgecrest 11."

Sol 984: Spirit measured atmospheric dust opacity with the panoramic camera and surveyed the sky, ground, and soil in the rover's tracks using the miniature thermal emission spectrometer. Spirit analyzed a rock target dubbed "O'Higgins" with the miniature thermal emission spectrometer and referenced instrument measurements to the calibration target on the rover. The rover scanned the sky for clouds with the navigation camera, measured morning sky brightness with the panoramic camera, and monitored dust on the panoramic camera mast assembly.

Sol 985: Spirit measured atmospheric opacity using the panoramic camera, surveyed the sky and ground with the miniature thermal emission spectrometer, and restarted analysis of dust collected by the filter magnets using the Mössbauer spectrometer. Spirit scanned the sky for clouds using the navigation camera and acquired thumbnail images of the sky with the panoramic camera.

Sol 986: Spirit measured atmospheric opacity using the panoramic camera, checked for drift (changes with time) in the miniature thermal emission spectrometer, and surveyed the sky and ground with the miniature thermal emission spectrometer. Spirit scanned the sky for clouds using the navigation camera and acquired thumbnail images of the sky with the panoramic camera.

Sol 987 (Oct. 12, 2006): Spirit measured atmospheric dust opacity using the panoramic camera, checked for drift in the miniature thermal emission spectrometer, and surveyed the sky and ground with the miniature thermal emission spectrometer. The rover restarted Mössbauer analysis of dust on the filter magnets. Spirit surveyed the sky during high sun using the panoramic camera.

Odometry:

As of sol 986 (Oct. 11, 2006), Spirit's total odometry remained at 6,876.18 meters (4.27 miles).


sol 977-981, October 13, 2006: Spirit Studies Layers of Volcanic Rock

Spirit is healthy and continues to make progress on a winter science campaign of experiments.

In parallel with normal planning, a special team has been developing plans to be executed during solar conjunction, when the sun obscures the line of sight between Earth and Mars and severely limits radio communication. Rover handlers will upload the plans to be executed by Spirit during solar conjunction prior to the beginning of conjunction. This year's solar conjunction period begins on the rover's 991st Martian day, or sol, (Oct. 16, 2006) and ends on sol 1005 (Oct. 30, 2006). Planning for future activities on sols 1006 and 1007 (Oct. 31 to Nov. 1, 2006) will resume Oct. 30.

Spirit continued to produce atmospheric profiles of dust, temperature at different heights, ice, and water vapor, as well as surface and sub-surface temperatures using the miniature thermal emission spectrometer. Plans also called for a scan of the sky for clouds, which, if found, could be incorporated into a multi-frame movie for observing cloud movement.

Spirit acquired super-resolution panoramic camera images of volcanic outcrops called
