| Description |
This photomosaic was taken by the Imager for Mars Pathfinder (IMP) camera on July 4, 1997 between 4:00-4:30 p.m. PDT. The foreground is dominated by the lander, newly renamed the Sagan Memorial Station after the late Dr. Carl Sagan. All three petals have been fully deployed. Upon one of the petals is the Sojourner microrover in its stowed position. The metallic cylinders at either end of Sojourner are the rover deployment ramps. Visible at the rear end (right) of the rover is the Alpha Proton X-Ray Spectrometer (APXS) instrument. Located to the right of the center petal is a dark, circular object and a bright, metallic object. Both are components of the high gain antenna. The black post, bull's-eye rings, and small shaded blocks in the far right portion of the image are components of the calibration targets. Terrain of the Ares Vallis region of Mars is in the background. The sections of soil and the large rocks surrounding the lander will provide the rover with numerous opportunities to employ the APXS. The prominent hills in the background will aid scientists in determining the exact site of the spacecraft. The dark blocks at the lower and upper left of the panorama represent gaps in the data transmission to Earth. Mars Pathfinder is the second in NASA's Discovery program of low- cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C. The Imager for Mars Pathfinder (IMP) was developed by the University of Arizona Lunar and Planetary Laboratory under contract to JPL. Peter Smith is the Principal Investigator. ##### |

| Description |
This picture taken by the IMP (Imager for Mars Pathfinder) aboard the Mars Pathfinder spacecraft depicts the rover Sojourner's position after driving onto the Martian surface. Sojourner has become the first autonomous robot ever to traverse the surface of Mars. This image reflects the success of Pathfinder's principle objective -- to place a payload on Mars in a safe, operational configuration. The primary mission of Sojourner, scheduled to last seven days, will be to use its Alpha Proton X-ray Spectrometer (APXS) instrument to determine the elements that make up the rocks and soil on Mars. A full study using the APXS takes approximately ten hours, and can measure all elements except hydrogen at any time of the Martian day or night. The APXS will conduct its studies by bombarding rocks and soil samples with alpha particle radiation -- charged particles equivalent to the nucleus of a helium atom, consisting of two protons and two neutrons. Mars Pathfinder is the second in NASA's Discovery program of low- cost spacecraft with highly focused science goals.

| Description |
The image was taken by the Imager for Mars Pathfinder (IMP) on Sol 4. The rover Sojourner has traveled to an area of soil and several rocks. Its tracks are clearly visible in the soft soil seen in the foreground, and were made in part by the rover's material abrasion experiment. Scientists were able to control the force of the rover's cleated wheels to help determine the physical properties of the soil. In this image, Sojourner is using its Alpha Proton X-Ray Spectrometer (APXS) instrument to study an area of soil. Sunlight is striking the area from the left, creating shadows under Sojourner and at the right of local rocks. The large rock Yogi can be seen at upper right. Mars Pathfinder is the second in NASA's Discovery program of low- cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C. JPL is an operating division of the California Institute of Technology (Caltech).

Deflated Airbags and Yogi

Deflated Airbags and Yogi |
| Description |
The left portion of this image, taken by the Imager for Mars Pathfinder (IMP) on Sol 3, shows the large rock nicknamed "Yogi." Portions of a petal and deflated airbag are in the foreground. Yogi has been an object of study for rover Sojourner's Alpha Proton X-Ray Spectrometer (APXS) instrument. The APXS will help Pathfinder scientists learn more about the chemical composition of that rock.
