| Description |
The parachute for NASA's Mars Science Laboratory (MSL) passed flight-qualification after testing in March and April 2009 inside the world's largest wind tunnel at NASA's Ames Research Center. In this image, an engineer is dwarfed by the parachute, the largest ever built to fly on an extraterrestrial flight. It is designed to survive deployment at Mach 2.2 in the Martian atmosphere, where it will generate up to 65,000 lb of drag force. The parachute, built by Pioneer Aerospace, has 80 suspension lines, measures more than 165 feet in length, and opens to a diameter of nearly 51 feet. The wind tunnel itself is 80 feet tall and 120 feet wide -- large enough to house a Boeing 737. JPL is building and testing the MSL spacecraft, which is slated to launch in 2011. The mission will land a roving analytical laboratory on the surface of Mars in 2012. Image Credit: NASA/Ames Research Center/JPL |

…
11/2/09
| Description |
This view from the panoramic camera on NASA's Mars Exploration Rover Spirit shows the terrain surrounding the location called "Troy," where Spirit became embedded in soft soil during the spring of 2009. The hundreds of images combined into this view were taken beginning on the 1,906th Martian day (or sol) of Spirit's mission on Mars (May 14, 2009) and ending on Sol 1943 (June 20, 2009). Near the center of the image, in the distance, lies Husband Hill, where Spirit recorded views from the summit in 2005. For scale, the parallel tracks are about 1 meter (39 inches) apart. The track on the right is more evident because Spirit was driving backwards, dragging its right-front wheel, which no longer rotates. The bright soil in the center foreground is soft material in which Spirit became embedded after the wheels on that side cut through a darker top layer. The composition of different layers in the soil at the site became the subject of intense investigation by tools on Spirit's robotic arm. In recent weeks, Engineers have been using test rovers on Earth to prepare for extracting the sand-trapped Spirit rover. While amnesia-like symptoms in recent days might delay the start of planned drives by Spirit geared towards extricating it, the Mars Exploration Rover team remains hopeful. "If they are intermittent and infrequent, they are a nuisance that would set us back a day or two when they occur. If the condition becomes persistent or frequent, we will need to go to an alternate strategy that avoids depending on flash memory, " said Project Manager John Callas of NASA's Jet Propulsion Laboratory. In these amnesia events, Spirit fails to record data from the day's activities onto the type of computer memory -- non-volatile "flash" memory -- that can retain the data when the rover powers down for its energy-conserving periods of "sleep." Spirit has worked on Mars for more than 69 months in what was originally planned as a three-month mission. |

| Description |
This photograph shows the Mars Surveyor '98 Orbiter Color Imager, a high resolution camera that will be flown aboard a NASA orbiter in 1998. The camera will be built by Dr. Michael Malin of Malin Space Science Systems, Inc., San Diego, and the California Institute of Technology in Pasadena, Calif. This tiny instrument consists of two cameras with unique optics and identical focal plane assemblies, data acquisition system electronics and power supplies. The wide-angle camera will acquire daily weather maps of Mars with a surface resolution of 0.8 kilometers up to 7.2 kilometers (0.5 mile to 4.5 miles). The camera produces these maps in five spectral bands, including two ultraviolet bands that will characterize atmospheric ozone and provide global maps of other atmospheric phenomena such as clouds, hazes, dust storms and the polar hood. The medium-angle camera will be used to study selected areas of Mars with a resolution of 40 meters (131 feet) and observe alterations in the planet's surface over time due to changing atmospheric conditions and winds. Ten spectral channels will provide the ability to discriminate both atmospheric and surface features on the basis of composition. The Mars '98 Orbiter mission is tentatively scheduled for launch aboard a Med- Lite expendable launch vehicle in December 1998. The mission will be managed by NASA's Jet Propulsion Laboratory for NASA's Office of Space Science, Washington, D.C. ##### |

| Description |
This photo, taken during recent Mars Pathfinder testing, shows the lander opening its petals to expose the mini-rover (on left petal). Large air bags, deflated after landing, are seen below the petals. Pathfinder will spend about three hours after landing to reach this configuration. Once its petals are flush with the ground, two exit ramps will unfold to allow the rover easy access to the surface. By sunrise, the rover will be ready to stand up to its full height and take one of the two exit ramps off the lander and onto the Martian surface. There it will begin a week of science experiments on the surface of Mars. Pathfinder is managed by NASA's Jet Propulsion Laboratory and is scheduled for launch on Dec. 2, 1996. |

| Description |
Engineers recently tested these huge, multi-lobed air bags, which will envelope and protect the Mars Pathfinder spacecraft before it impacts the surface of Mars. The air bags, manufactured by ILC Dover of Frederica, Delaware, are composed of four large bags with six smaller, interconnected spheres within each bag. The bags measure 5 meters (17 feet) tall and about 5 meters (17 feet) in diameter. As Pathfinder is descending to the Martian surface on a parachute, an onboard altimeter inside the lander will monitor its distance from the ground. The computer will inflate these large air bags about 100 meters (330 feet) above the surface of Mars. The mission, managed by NASA's Jet Propulsion Laboratory, is scheduled for launch on Dec. 2, 1996. |

| Description |
This artist's rendering shows Pathfinder's unique descent to the surface of Mars. The spacecraft, enclosed in a cocoon of airbags, has just been severed from the tether which connected it to a huge parachute and Viking-derived heatshield used to slow the spacecraft's speed after entry in the Martian atmosphere. Once the spacecraft comes to a halt, the airbags will deflate and the spacecraft will stand itself right side up, then open its panels to expose its solar panels. As the sun rises over Mars, Pathfinder will power on, along with a miniature companion rover, called Sojourner, which sits on the inside of one of its panels. Sojourner will use one of two exit ramps to roll off the lander and drive onto the surface of Mars. There it will begin a week of science experiments on the surface of Mars, while the lander takes panoramic photographs of the Martian terrain. The Mars Pathfinder mission is managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, Washington, D.C., and is scheduled for launch from Cape Canaveral, Florida, atop a Delta II expendable launch vehicle on Dec. 2, 1996. ##### |

Two microprobes will hitchhike on the Mars Polar Lander, scheduled to be launched Jan. 3, 1999, aboard a Delta II rocket. The solar-powered spacecraft is designed to touch down on the Martian surface near the northern-most boundary of the south pole in order to study the water cycle there. The lander also will help scientists learn more about climate change and current resources on Mars, studying such things as frost, dust, water vapor and condensates in the Martian atmosphere. The Mars microprobes, called Deep Space 2, are part of NASA's New Millennium Program. They will complement the climate-related scientific focus of the lander by demonstrating an advanced, rugged microlaser system for detecting subsurface water.

The Sojourner rover and undeployed ramps onboard the Mars Pathfinder spacecraft can be seen in in this image, by the Imager for Mars Pathfinder (IMP) on July 4 (Sol 1). This image has been corrected for the curvature created by parallax. The microrover Sojourner is latched to the petal, and has not yet been deployed. The ramps are a pair of deployable metal reels which will provide a track for the rover as it slowly rolls off the lander, over the spacecraft's deflated airbags, and onto the surface of Mars. Pathfinder scientists will use this image to determine whether it is safe to deploy the ramps. One or both of the ramps will be unfurled, and then scientists will decide whether the rover will use either the forward or backward ramp for its descent. 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.

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.

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.

The Mars Surveyor '98 Climate Orbiter, which is entering the final stages of testing this summer at Lockheed Martin Astronautics, Denver, CO, is shown here during acoustic tests that simulate launch conditions. The orbiter will conduct a two- year primary mission to profile the Martian atmosphere and map the surface. To carry out these scientific objectives, the spacecraft will carry a rebuilt version of the pressure-modulated infrared radiometer, lost with the Mars Observer spacecraft, and a miniaturized dual camera system the size of a pair of binoculars, provided by Malin Space Science Systems, Inc., San Diego, CA. During its primary mission, the orbiter will monitor Mars' atmosphere and surface globally on a daily basis for one Martian year (two Earth years), observing the appearance and movement of atmospheric dust and water vapor, as well as characterizing seasonal changes of the planet's surface. Imaging of the surface morphology will also provide important clues about the planet's climate in its early history. The mission is part of NASA's Mars Surveyor program, a sustained program of robotic exploration of the red planet, managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, Washington, DC.

| Description |
This is one of the first pictures taken by the camera on the Mars Pathfinder lander shortly after its touchdown at 10:07 AM Pacific Daylight Time on July 4, 1997. The small rover, named Sojourner, is seen in the foreground in its position on a solar panel of the lander. The white material on either side of the rover is part of the deflated airbag system used to absorb the shock of the landing. Between the rover and the horizon is the rock-strewn martian surface. Two hills are seen in the right distance, profiled against the light brown sky. Pathfinder, a low-cost Discovery mission, is the first of a new fleet of spacecraft that are planned to explore Mars over the next ten years. Mars Global Surveyor, already en route, arrives at Mars on September 11 to begin a two year orbital reconnaissance of the planet's composition, topography, and climate. Additional orbiters and landers will follow every 26 months. 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). 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 |
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.

| Description |
The Mars Polar Lander is shown on the surface of Mars. The spacecraft will travel 10 months from Earth to Mars to land near the southern polar cap in December 1999 and carry out a three- month mission to search for traces of subsurface water in this frozen, layered terrain. The lander carries three scientific packages: the Mars descent imager, furnished by Malin Space Science Systems, Inc., which will view the landing site at increasingly higher resolution, the atmospheric lidar experiment, provided by Russia's Space Research Institute, which will measure the presence and height of atmospheric hazes, along with a miniature microphone provided by The Planetary Society, to record the sounds of Mars, and the Mars Volatile and Climate Surveyor science package. The mission is part of NASA's Mars Surveyor program, a sustained program of robotic exploration of the red planet, managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, Washington, DC.

| Description |
NASA's Galileo spacecraft caught this volcanic eruption in action on Jupiter's moon Io on November 25, 1999. This mosaic shows Tvashtar Catena, a chain of calderas, in enhanced color. It combines low resolution (1.3 kilometers, or .8 miles, per picture element) color images of Io taken on July 3, 1999 with the much higher resolution (180 meters, or 197 yards, per picture element) black and white images taken in November. The molten lava was hot enough, and therefore bright enough, to saturate, or overexpose, Galileo's camera (original image is inset in lower right corner). The bright lava curtain (a chain of lava fountains) and surface flows shown in the color image were assembled as an interpretive drawing by Galileo scientists, based on their knowledge of how the camera behaves when saturated. The lava appears to be producing fountains to heights of up to 1.5 kilometers (5,000 feet) above the surface. Several other lava flows can be seen on the floors of the calderas. The darkest flows are probably the most recent. The elongated caldera in the center of the image is almost surrounded by a mesa that is about 1 kilometer (.6 miles) high. In places the mesa's margins are scalloped, which is typical of an erosional process called sapping. This occurs when fluid escapes from the base of a cliff, causing the material above it to collapse. On Earth, sapping is caused by springs of groundwater. Similar features on Mars are one of the key pieces of evidence that water flowed on Mars' surface in the past. On Io, the fluid is believed to be sulfur dioxide, which should vaporize almost instantaneously when it reaches the near vacuum at Io's surface, blasting away material at the base of the cliffs. North is to the top of the image and the Sun illuminates the surface from the lower left. The high resolution black and white image was taken at a distance of 17,000 kilometers (11,000 miles).

| Description |
This pair of images taken by NASA's Galileo spacecraft captures a dynamic eruption at Tvashtar Catena, a chain of volcanic bowls on Jupiter's moon Io. They show a change in the location of hot lava over a period of a few months in 1999 and early 2000. The image on the left uses data obtained on Nov. 26 and July 3, 1999, at resolutions of 183 meters (600 feet) and 1.3 kilometers (0.8 miles) per pixel, respectively. The red and yellow lava flow itself is an illustration based upon imaging data. The image on the right is a composite using a five-color observation made on Feb. 22, 2000, at 315 meters (1030 feet) per pixel. These are among the most fortuitous observations made by Galileo because this style of volcanism is too unpredictable and short-lived to plan to photograph. Short-lived bursts of volcanic activity on Io had been previously detected from Earth-based observations, but interpreting the style of volcanic activity from those lower- resolution views was highly speculative. These Galileo observations confirm hypotheses that the initial, intense thermal output comes from active lava fountains. Galileo's high-resolution observations of volcanic activity on Io have also confirmed other hypotheses based on earlier, low- resolution data. These include interpretations of slowly spreading lava flows at Prometheus and Amirani and an active lava lake at Pele. These tests of earlier hypotheses increase scientists' confidence in interpreting volcanic activity seen in low-resolution remote sensing data of Earth as well as Io. However, these data are still of insufficient resolution to adequately test the more quantitative models that have been applied to volcanic eruptions on Earth and Io. These images also show other geologic features on Io, such as the scalloped margins of the plateau to the northeast of the active lavas. These margins appear to have formed by sapping, a process usually associated with springs of water. Liquid sulfur dioxide might be the fluid responsible for sapping on Io. A better understanding of sapping on Io will influence how scientists interpret similar features on Mars (where the viability of carbon dioxide or water as the sapping fluid remains controversial).

Riding a Trail of Debris
| Title |
Riding a Trail of Debris |
| Description |
This image taken by NASA's Spitzer Space Telescope shows the comet Encke riding along its pebbly trail of debris (long diagonal line) between the orbits of Mars and Jupiter. This material actually encircles the solar system, following the path of Encke's orbit. Twin jets of material can also be seen shooting away from the comet in the short, fan-shaped emission, spreading horizontally from the comet. Encke, which orbits the Sun every 3.3 years, is well traveled. Having exhausted its supply of fine particles, it now leaves a long trail of larger more gravel-like debris, about one millimeter in size or greater. Every October, Earth passes through Encke's wake, resulting in the well-known Taurid meteor shower. This image was captured by Spitzer's multiband imaging photometer when Encke was 2.6 times farther away than Earth is from the Sun. It is the best yet mid-infrared view of the comet at this great distance. The data are helping astronomers understand how rotating comets eject particles as they circle the Sun. |

Band of Rubble
| Title |
Band of Rubble |
| Description |
This artist's animation illustrates a massive asteroid belt in orbit around a star the same age and size as our Sun. Evidence for this possible belt was discovered by NASA's Spitzer Space Telescope when it spotted warm dust around the star, presumably from asteroids smashing together. The view starts from outside the belt, where planets like the one shown here might possibly reside, then moves into to the dusty belt itself. A collision between two asteroids is depicted near the end of the movie. Collisions like this replenish the dust in the asteroid belt, making it detectable to Spitzer. The alien belt circles a faint, nearby star called HD 69830 located 41 light-years away in the constellation Puppis. Compared to our own solar system's asteroid belt, this one is larger and closer to its star -- it is 25 times as massive, and lies just inside an orbit equivalent to that of Venus. Our asteroid belt circles between the orbits of Mars and Jupiter. Because Jupiter acts as an outer wall to our asteroid belt, shepherding its debris into a series of bands, it is possible that an unseen planet is likewise marshalling this belt's rubble. Previous observations using the radial velocity technique did not locate any large gas giant planets, indicating that any planets present in this system would have to be the size of Saturn or smaller. Asteroids are chunks of rock from "failed" planets, which never managed to coalesce into full-sized planets. Asteroid belts can be thought of as construction sites that accompany the building of rocky planets. |

Birth of an Earth-like Planet |
| Description |
This artist's conception shows a binary-star, or two-star, system, called HD 113766, where astronomers suspect a rocky Earth-like planet is forming around one of the stars. At approximately 10 to 16 million years old, astronomers suspect this star is at just the right age for forming rocky planets. The system is located approximately 424 light-years away from Earth. The two yellow spots in the image represent the system's two stars. The brown ring of material circling closest to the central star depicts a huge belt of dusty material, more than 100 times as much as in our asteroid belt, or enough to build a Mars-size planet or larger. The rocky material in the belt represents the early stages of planet formation, when dust grains clump together to form rocks, and rocks collide to form even more massive rocky bodies called planetesimals. The belt is located in the middle of the system's terrestrial habitable zone, or the region around a star where liquid water could exist on any rocky planets that might form. Earth is located in the middle of our Sun's terrestrial habitable zone. Using NASA's Spitzer Space Telescope, astronomers learned that the belt material in HD 113866 is more processed than the snowball-like stuff that makes up infant solar systems and comets, which contain pristine ingredients from the early solar system. However, it is not as processed as the stuff found in mature planets and asteroids. This means that the dust belt is made out of just the right mix of materials to be forming an Earth-like planet. It is composed mainly of rocky silicates and metal sulfides (like fool's gold), similar to the material found in lava flows. The white outer ring shows a concentration of icy dust also detected in the system. This material is at the equivalent position of the asteroid belt in our solar system, but only contains about one-sixth as much material as the inner ring. Astronomers say it is not clear from the Spitzer observations if anything is occurring in the icy belt, but they believe it could be a source of water later on for the planet that grows from the inner warm ring. |

Evidence for Strange Stellar Family |
| Description |
This artist concept depicts a quadruple-star system called HD 98800. The system is approximately 10 million years old, and is located 150 light-years away in the constellation TW Hydrae. HD 98800 contains four stars, which are paired off into doublets, or binaries. The stars in the binary pairs orbit around each other, and the two pairs also circle each other like choreographed ballerinas. One of the stellar pairs, called HD 98800B, has a disk of dust around it, while the other pair does not. Although the four stars are gravitationally bound, the distance separating the two binary pairs is about 50 astronomical units (AU) -- slightly more than the average distance between our sun and Pluto. Using NASA's Spitzer Space Telescope, scientists finally have a detailed view of HD 98800B's potential planet-forming disk. Astronomers used the telescope's infrared spectrometer to detect the presence of two belts in the disk made of large dust grains. One belt sits approximately 5.9 AU away from the central binary, or about the distance from the sun to Jupiter, and is likely made up of asteroids and comets. The other belt sits at 1.5 to 2 AU, comparable to the area where Mars and the asteroid belt sit, and consists of fine dust grains. |

Artist's Conception of Sedna |
| Description |
In this artist's visualization, the newly discovered planet-like object, dubbed "Sedna," is shown where it resides at the outer edges of the known solar system. The object is so far away that the Sun appears as an extremely bright star instead of the large, warm disc observed from Earth. All that is known about Sedna's appearance is that it has a reddish hue, almost as red and reflective as the planet Mars. In the distance is a hypothetical small moon, which scientists believe may be orbiting this distant body. |
