(AP Photo/Gregorio Borgia) Europe’s experimental Mars probe hit the right spot—but at the wrong speed—and may have ended up in a fiery ball of rocket fuel when it struck the surface, scientists said Friday. Pictures taken by a NASA satellite show a black spot in the area where the Schiaparelli lander was meant to touch down Wednesday, the European Space Agency said. The images end two days of speculation following the probe’s unexpected radio silence less than a minute before the planned landing.
”Estimates are that Schiaparelli dropped from a height of between 2 and 4 kilometers (1.4-2.4 miles), therefore impacting at a considerable speed, greater than 300 kilometers per hour (186 mph),” the agency said.
It said the large disturbance captured in the NASA photographs may have been caused by the probe’s steep crash-landing, which would have sprayed matter around like a blast site on Earth.
”It is also possible that the lander exploded on impact, as its thruster propellant tanks were likely still full,” the agency said.
Schiaparelli was designed to test technology for a more ambitious European Mars landing in 2020. The European Space Agency said the probe’s mother ship was successfully placed into orbit Wednesday and will soon begin analyzing the Martian atmosphere in search for evidence of life.
”In my heart, of course I’m sad that we couldn’t land softly on the surface of Mars,” ESA chief Jan Woerner told The Associated Press. ”But the main part of the mission is the science that will be done by the orbiter.”
Woerner said engineers received a wealth of data from the lander before the crash that will prove valuable for the next attempt in four years’ time. He described the mission as ”a 96 percent success.” Italian Space Agency President Roberto Battiston holds a pamphlet reading in Italian ’Colonize Mars, Friday, Oct. 19, 2016, in front of a rendering showing the Schiaparelli Space Module and the planet Mars as they follow during an event organized by Italy’s Space Agency, the insertion of the Trace Gas Orbiter into orbit around Mars, and the landing of the Schiaparelli module on the surface of the planet.

Its resting place was photographed by NASA’s Mars Reconnaissance Orbiter, which also spotted Europe’s last ill-fated mission to the surface of the planet. The Beagle 2 probe landed on Mars in 2003 but failed to deploy its solar panels properly, preventing it from functioning.
There have only been seven successful robotic landings on Mars, all by NASA. The last landing was in 2012, when the Curiosity rover touched down in a Martian crater.
Landing on Mars is notoriously difficult because of the planet’s thin, dusty atmosphere. Inbound spacecraft hit the atmosphere at 12,000 mph (19,300 kph) and have only minutes to slow down and land.
With the loss of Schiaparelli, only two spacecraft are currently roaming the Martian surface—Curiosity and Opportunity, which landed in 2004.
ESA said that, according to what its scientists have been able to piece together so far, Schiaparelli suffered problems during the last 50 seconds of its descent through the harsh Martian atmosphere.
The picture taken by NASA’s orbiter shows two features that weren’t visible on the surface when the spacecraft photographed the area in May. The first is a bright spot of about 12 meters diameter, likely to be Schiaparelli’s parachute, ESA said.
The second was described as ”a fuzzy dark patch roughly 15 by 40 meters in size and about 1 kilometer north of the parachute” and is likely to be the lander. A model of Schiaparelli· the mars landing device , is on display at the European Space Agency, ESA, in Darmstadt, Germany Wednesday Oct. 19, 2016. Schiaparelli will enter the martian atmosphere at an altitude of about 121 km and a speed of nearly 21 000 km/h. Less than six minutes later it will have landed on Mars. The probe will take images of Mars and conduct scientific measurements on the surface, but its main purpose is to test technology for a future European Mars rover.

While Schiaparelli was able to beam back some 600 megabytes of data before the crash, scientists won’t get any of the close-up photos the probe took during its descent. Those were meant to be transmitted after the landing.
ESA said the other part of the ExoMars mission—the Trace Gas Orbiter—was ”working very well and will take science calibration data during two orbits in November.”
The spacecraft will then descend to an altitude of about 400 kilometers and begin its study of Mars next year. The orbiter is also going to act as a radio relay for the next stage of the ExoMars mission and other future attempts to land on the planet.
