A new study claims a recently discovered meteorite is a chunk of Martian crust that is like nothing else ever discovered on Earth.
The meteorite, known as NWA 7034, weighs just 11 ounces. It was discovered in the Moroccan desert in 2011 and eventually sold to a collector in the U.S.
'Black Beauty' meteorite reveals secrets of Mars' surface
The image shows part of the Arabia Terra region, which is scattered with craters of varying sizes and ages. The craters in this image, caused by impacts in Mars’ past, all show different degrees of erosion. Some still have defined outer rims and clear features within them, while others are much smoother and featureless, almost seeming to run into one another or merge with their surroundings.
This color image was taken by Mars Express’s High Resolution Stereo Camera on 19 November 2014, during orbit 13728. The image resolution is about 20 m per pixel.

IN SPACE - SEPTEMBER 2: In this handout image provided by NASA/JPL-Caltech/MSSS, and captured by NASA's Curiosity rover, a rock outcrop called Link pops out from a Martian surface that is elsewhere blanketed by reddish-brown dust, showing evidence for an ancient, flowing stream, September 2, 2012. The fractured Link outcrop has blocks of exposed, clean surfaces. Rounded gravel fragments, or clasts, up to a couple inches (few centimeters) in size are in a matrix of white material. Many gravel-sized rocks have eroded out of the outcrop onto the surface, particularly in the left portion of the frame. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. Water transport is the only process capable of producing the rounded shape of clasts of this size. (Photo by NASA/JPL-Caltech/MSSS via Getty Images)
IN SPACE - AUGUST 8: In this handout image provided by NASA and released on August 8, 2012, the four main pieces of hardware that arrived on Mars with NASA's Curiosity rover are spotted by NASA's Mars Reconnaissance Orbiter (MRO). The High-Resolution Imaging Science Experiment (HiRISE) camera captured this image about 24 hours after landing. The large, reduced-scale image points out the strewn hardware: the heat shield was the first piece to hit the ground, followed by the back shell attached to the parachute, then the rover itself touched down, and finally, after cables were cut, the sky crane flew away to the northwest and crashed. The relatively dark areas in all four spots are from disturbances of the bright dust on Mars, revealing the darker material below the surface dust.

IN SPACE - AUGUST 5: In this handout image provided by NASA/JPL-Caltech/MSSS, This color thumbnail image was obtained by NASA's Curiosity rover during its descent to the surface on Aug. 5 PDT and transmitted to Spaceflight Operations Facility for NASA's Mars Science Laboratory Curiosity rover at Jet Propulsion Laboratory (JPL) in Pasadena, California. The image from Curiosity's Mars Descent Imager illustrates the roughly circular swirls of dust kicked up from the Martian surface by the rocket motor exhaust. At this point, Curiosity is about 70 feet (20 meters) above the surface. This dust cloud was generated when the Curiosity rover was being lowered to the surface while the Sky Crane hovered above. This is the first image of the direct effects of rocket motor plumes on Mars and illustrates the mobility of powder-like dust on the Martian surface. It is among the first color images Curiosity sent back from Mars. The original image from MARDI has been geometrically corrected to look flat. The MSL Rover named Curiosity is equipped with a nuclear-powered lab capable of vaporizing rocks and ingesting soil, measuring habitability, and whether Mars ever had an environment able to support small life forms called microbe.

WINDJANA, MARS - APRIL/MAY 2015: In this handout composite provided by NASA/JPL-Caltech/MSSS NASA's Curiosity Mars rover used the camera at the end of its arm in April and May 2014 to take dozens of component images combined into this self-portrait where the rover drilled into a sandstone target called 'Windjana.' The camera is the Mars Hand Lens Imager (MAHLI), which previously recorded portraits of Curiosity at two other important sites during the mission. (Photo by NASA/JPL-Caltech/MSSS via Getty Images)

This image illustrates possible ways methane might be added to Mars' atmosphere (sources) and removed from the atmosphere (sinks). NASA's Curiosity Mars rover has detected fluctuations in methane concentration in the atmosphere, implying both types of activity occur on modern Mars. A longer caption discusses which are sources and which are sinks.(Credit: NASA/JPL-Caltech/SAM-GSFC/Univ. of Michigan)

According to the study by researchers from Brown University and the University of New Mexico, the meteorite, known as "Black Beauty," is about 4.4 billion years old.
When researchers first examined the rock, its chemical makeup confirmed it was indeed from Mars, but it was completely different from any sample ever discovered before.
The majority of the samples from Mars' surface are made from cooled volcanic material. Black Beauty, however, is made up of small fragments of different rocks all welded together - known as a breccia rock.
The planet has more than 400,000 impact craters of at least 1 km in diameter. Impacts of that magnitude are known to cause those brecciated rocks, leading researchers to believe this rock would be characteristic of much of the Red Planet's surface.
"If you went to Mars and picked up a chunk of crust, you'd expect it to be heavily beat up, battered, broken apart and put back together."
