InSight: NASA's Next Mars Lander to Begin Construction
The next NASA robot to touch down on the surface of Mars will soon begin taking shape.
The next NASA robot to touch down on the surface of Mars will soon begin taking shape.
NASA's InSight Mars lander, which is scheduled to launch toward the Red Planet in March 2016, passed a key design review Friday (May 16), clearing the way for construction of the spacecraft to begin.
"Our partners across the globe have made significant progress in getting to this point and are fully prepared to deliver their hardware to system integration starting this November, which is the next major milestone for the project," InSight project manager Tom Hoffman, of NASA's Jet Propulsion Laboratory in Pasadena, California, said in a statement.

"We now move from doing the design and analysis to building and testing the hardware and software that will get us to Mars and collect the science that we need to achieve mission success," Hoffman added.
The $425 million InSight mission - whose name is short for Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport - will measure heat flow from the planet's interior and study the motion of seismic waves generated by "Marsquakes" and meteorite impacts.
Mission scientists will also use the communications link between InSight and NASA's Deep Space Network antennas to measure the tiny wobble in Mars' rotation. Such information could reveal whether the Red Planet has a solid core or a molten one like Earth's.
The robot's two-year mission should shed light on how rocky planets such as Earth form and evolve, mission team members said.
"Mars actually offers an advantage over Earth itself for understanding how habitable planetary surfaces can form," InSight principal investigator Bruce Banerdt, also of JPL, said in a statement. "Both planets underwent the same early processes. But Mars, being smaller, cooled faster and became less active while Earth kept churning. So Mars better preserves the evidence about the early stages of rocky planets' development."
The InSight spacecraft is based heavily on NASA's Phoenix lander, which discovered water ice after touching down near the Martian north pole in 2008. But InSight will head to a spot near the Red Planet's equator. And there are other differences as well.
"We will incorporate many features from our Phoenix spacecraft into InSight, but the differences between the missions require some differences in the InSight spacecraft," said InSight program manager Stu Spath, of Lockheed Martin Space Systems Co. in Denver. "For example, the InSight mission duration is 630 days longer than Phoenix, which means the lander will have to endure a wider range of environmental conditions on the surface."

This artist's concept depicts the stationary NASA Mars lander known by the acronym InSight at work studying the interior of Mars. The InSight mission (for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) is scheduled to launch in March 2016 and land on Mars six months later.

The High Resolution Imaging Science Experiment (HiRISE) camera is the most powerful imager in orbit around Mars. Capable of resolving objects less than a meter wide on the surface of the Red Planet while attached to NASA's Mars Reconnaissance Orbiter (MRO), HiRISE has brought us unparallelled views of Martian landscape, geology, active erosion processes and even our own surface missions.
After nearly 8 years of orbiting Mars, HiRISE has amassed a huge archive of observations and, in many cases, observations can be combined to provide a unique insight to the planet's topography -- an observation that can be difficult to make with a single top-down snapshot.
Therefore, the HiRISE team use "stereo pairs" of observations from different orbital passes (and therefore different viewing angles) of the same locations on the Martian surface. This can produce topographical maps of surface features accurate to within 10s of centimeters in height. These high resolution digital terrain models, or DTMs, provide an incredible scientific insight as well as constructing an aesthetically pleasing perspective of an otherwise "flat" vista. In all images a color spectrum of purple-white is used, where the purple/blue hues are the lowest lying land and the red/white hues are the highest. Here are some of our favorite DTM images.
Shown here are the stunning "moving dunes" of Nili Patera (catalog number: ESP_017762_1890)
Elevation range: 55 meters (purple/blue - lowest) to 275 meters (red/white - highest) above mean Mars surface elevation.
DTMs can be very useful when trying to understand the morphology of craters on the Martian surface. This is Raga Crater, featuring very steep crater slopes in its interior (ESP_014011_1315).
Elevation range: 1,311 meters (purple/blue - lowest) to 1,966 meters (red/white - highest) above mean Mars surface elevation.
This is one of the stereo pairs of images used to compose the DTM of Raga Crater (see previous slide). Although this HiRISE image provides incredible high-resolution imagery of the feature, there is little elevation data, something the DTM provides through its topographical color spectrum (ESP_014011_1315).
The rim of Endeavour Crater in Meridiani Planum. Since 2011, Mars rover Opportunity has been extensively studying the crater's rim, turning up exciting evidence of past water on the Martian surface. The HiRISE DTMs have played a key role in mapping the rover's drive in the region (ESP_018701_1775)
Elevation range: -1,695 meters (purple/blue - lowest) to -1,380 meters (red/white - highest) below mean Mars surface elevation.
The barchan dunes on Mars can be monstrous structures. This example is nearly 300 meters high and features a steep slip face where there appear to be obvious signs of avalanches having taken place (PSP_006899_1330).
Elevation range: 1,031 meters (purple/blue - lowest) to 1,321 meters (red/white - highest) above mean Mars surface elevation.
This may look like a shooting star cartoon, but it's actually an old impact crater plus ridge of dunes in Athabasca Valles. The "tail" of material is likely caused by prevailing winds shaping the landscape (PSP_002661_1895).
Elevation range: -2,611 meters (purple/blue - lowest) to -2,441 meters (red/white - highest) below mean Mars surface elevation.
Victoria Crater in Meridiani Planum, a crater explored by Mars Exploration Rover Opportunity from September 2006 to August 2008 (PSP_001414_1780).
Elevation range: -1,453 meters (purple/blue - lowest) to -1,373 meters (red/white - highest) below mean Mars surface elevation.
Small cones in an ancient volcanic region of mars, formed by molten lava flowing over ice or water (ESP_018747_2065).
Elevation range: -3,262 meters (purple/blue - lowest) to -3,196 meters (red/white - highest) below mean Mars surface elevation.
A deep channel formed by the ancient flow of water in the Tartarus Colles Region. A small island is evident in the meandering channel (ESP_012444_2065).
Elevation range: -3,301 meters (purple/blue - lowest) to -3,189 meters (red/white - highest) below mean Mars surface elevation.
Zooming in on Gasa Crater reveals gullies formed through erosion (ESP_021584_1440)
Elevation range: -704 meters (purple/blue - lowest) to 581 meters (red/white - highest) above mean Mars surface elevation.
The "inverted valleys" near Juventae Chasma were once the floor of valleys. But over time, the topographic low regions, which are composed of material resistant to erosion (likely cemented there by water sedimentation), become ridges as the softer material around them eroded below the ancient valley floors (PSP_007627_1765).
Elevation range: 2,128 meters (purple/blue - lowest) to 2,234 meters (red/white - highest) above mean Mars surface elevation.
A well-preserved 3 kilometer-wide impact crater (ESP_012991_1335).
Elevation range: 1,114 meters (purple/blue - lowest) to 1,742 meters (red/white - highest) above mean Mars surface elevation.
A mound in Ganges Chasma. Using the topographical color reference, this feature is approximately 800 meters high from base to peak. The arcing structure around the mound may be a wind-blown ridge of material surrounding the obstacle (ESP_017173_1715).
Elevation range: -3,716 meters (purple/blue) to -2,711 meters (red/white) below mean Mars surface elevation.
Inside a crater in Western Arabia Terra with stair-stepped hills and dunes.
Elevation range: -2,575 meters (purple/blue) to -2,259 meters (red/white) below mean Mars surface elevation.
A fresh impact crater. Newly formed craters on Mars have smooth ridges and are often circular. Older craters undergo atmospheric erosion processes, often causing the ridges to appear broken, frayed and slumped (PSP_005837_1965).
Elevation range: -4,304 meters (purple/blue) to -3,658 meters (red/white) below mean Mars surface elevation.
Layered surface deposits of material in the north polar region of Mars leave a step-like pattern (ESP_018870_2625).

A deep fissure scars the Martian surface, a possible source of ancient floodwater (PSP_010361_1955).
Elevation range: -2,747 meters (purple/blue) to -1,577 meters (red/white) below mean Mars surface elevation.
At the base of shield volcano Ascraeus Mons' slopes in the Tharsis Region, ancient river and tributary channels carve up the landscape (PSP_002486_1860).
Elevation range: 6,432 meters (purple/blue) to 6,675 meters (red/white) below mean Mars surface elevation.
A distributary channel -- a river that branches off and flows away from a main channel -- can be seen flowing down the base of Ascraeus Mons (ESP_011373_1865).
Elevation range: 6,568 meters (purple/blue) to 6,766 meters (red/white) below mean Mars surface elevation.
