Flying Over Spirit's Work Site
- March 13, 2007
Images of the "Columbia Hills" region inside Mars' Gusev Crater, taken by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter, provided detailed, three-dimensional information that was used to create this animation of a hypothetical flyover. NASA's Mars Exploration Rover Spirit has been exploring this range of hills since 2004.

Special-Effects Spirit on Flank of "Husband Hill"
- January 23, 2006
This synthetic image of the Spirit Mars Exploration Rover on the flank of "Husband Hill" was produced using "Virtual Presence in Space" technology. Developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif., this technology combines visualization and image-processing tools with Hollywood-style special effects. The image was created using a photorealistic model of the rover and a false-color mosaic. The size of the rover in the image is approximately correct and was based on the size of the rover tracks in the mosaic. The mosaic was assembled from frames taken by the panoramic camera on the rover's 454th Martian day, or sol (April 13, 2005); see PIA07855.
Because this synthesis provides viewers with a sense of their own "virtual presence" (as if they were there themselves), such views can be useful to mission teams in planning exploration by enhancing perspective and a sense of scale.

Aerial View of Spirit's Journey - June 03, 2005
This video clip shows a simulated aerial view of Spirit's journey through the "Columbia Hills" on Mars. The U.S. Geological Survey created the three-dimensional digital terrain model using images from the Mars Orbital Camera on the Mars Global Surveyor satellite. Released June 3, 2005, the route shows the rover's progress from martian day, or sol, 149 (June 3, 2004) through sol 502 (May 31, 2005), at which time the rover had traveled 3.9 kilometers (2.4 miles) since landing on Mars in January, 2004. The video was processed using a method called Incremental Bundle Adjustment developed at Ohio State University, which corrects traverse errors for improved rover positions.

Spirit's Trek to Bonneville - March 09, 2004
Early in her mission, Spirit was assigned the long-term goal of reaching the crater dubbed "Bonneville." On her way there, she's made multiple pit-stops to study curious rocks and image eye-catching geological features. In "Spirit's Trek to Bonneville," science team member Diana Blaney and rover engineeer Art Thompson talk about the intriguing and challenging journey across the martian surface.

3-D Perspective of Adirondack - Jan 19, 2004
This 3-D perspective "video" made from images taken by the panoramic camera onboard the Mars Exploration Rover Spirit shows "Adirondack," the rover's first target rock. Spirit traversed the sandy martian terrain at Gusev Crater to arrive in front of the football-sized rock on Sunday, Jan. 18, 2004, just three days after it successfully rolled off the lander. The rock was selected as Spirit's first target because it has a flat surface and is relatively free of dust - ideal conditions for grinding into the rock to expose fresh rock underneath. Clean surfaces also are better for examining a rock's top coating. Scientists named the angular rock after the Adirondack mountain range in New York. The word Adirondack is Native American and is interpreted by some to mean "They of the great rocks." Data from the panoramic camera's red, green and blue filters were combined to create this true color image.

Virtual Rover Drives Toward Rock - Jan 19, 2004
This video was rendered from the software used by
engineers to test and drive the Mars Exploration Rover Spirit.
The software simulates the rover's movements across the martian
terrain, helping to plot a safe course. Here, engineers simulated Spirit's first post-egress drive on Mars Sunday. The 3-meter (10-foot) drive totaled approximately 30 minutes, including time to stop and take images. The rover drove toward its first rock target, a mountain-shaped rock called Adirondack. The blue line denotes the path of the rover's "belly button," as engineers like to call it, as the rover drove toward Adirondack. The virtual 3-D world around the rover was built from images taken by Spirit's stereo navigation cameras. Regions for which the rover has not yet acquired 3-D data are represented in beige.

Rover Takes a Sunday Drive - Jan 19, 2004
This animation, made with images from the Mars Exploration Rover Spirit hazard-avoidance camera, shows the rover's perspective of its first post-egress drive on Mars Sunday. Engineers drove Spirit approximately 3 meters (10 feet) toward its first rock target, a football-sized, mountain-shaped rock called Adirondack. The drive took approximately 30 minutes to complete, including time stopped to take images. Spirit first made a series of arcing turns totaling approximately 1 meter (3 feet). It then turned in place and made a series of short, straightforward movements totaling approximately 2 meters (6.5 feet).
