A new image of Schiaparellis intended landing site, captured by the Mars Reconnaissance Orbiters Context Camera on October 20th, shows several surface features that seem related to the wayward lander. According to a statement issued by ESA today, the bright spot in the southeast corner of the boxed area above is interpreted to be Schiaparellis parachute, while the darker, fuzzy splotch less than a mile north is probably an impact site following a much longer free fall than planned, after the thrusters were switched off prematurely.

(40,416 posts)First, it is really, really difficult to land safely on Mars. The atmosphere is very, very thin, so parachutes are both obligatory and nearly useless. And Mars' mass is too large to go without a parachute. You are basically screwn landing on Mars, which is why so many spacecraft have crashed attempting it. Plus, it helps if the lander knows the difference between metric and English units.
Second, by the time the lander is to set down, it is minutes in the past, even when Mars is close. So there is no real-time control. Google "seven minutes of terror" for an exemplar of the Curiosity rover's descent, all done with the JPL controllers absolutely blind and seven minutes behind, longer than Curiosity's descent!
Hopefully, ESO will get it together for their big launch to Mars.

Going to Mars or anywhere in space is a very difficult endeavor. Hopefully ESA will be able to nail down the reason for this loss and learn from it and go forward with another mission. 🚀🛰🚀

ESA's Schiaparelli Mars lander exploded on impact, Nasa images suggest
Hannah Devlin Science correspondent

The landing site of a European spacecraft that was supposed to make a historic touchdown on Mars this week has been identified in images that suggest the probe suffered a violent collision at the surface.
Images from Nasa Mars Reconnaissance Orbiter show a large fuzzy dark patch that scientists think was caused by huge plumes of dust thrown up in a high-speed crash - and may even indicate the probe exploded on impact. Theprobe is believed to have gone down with full fuel tanks far faster than planned because its retrorockets, intended to slow it down, fired for only a few seconds before switching off prematurely.
A second, brighter, surface feature is thought to be the 12-metre-wide parachute, which the Schiaparelli lander jettisoned during descent.
The latest observations confirm what most European Space Agency (ESA) scientists were already resigned to: that what was supposed to be a historic first scientific mission on Mars for Europe had been scuppered at the last moment. The rapid location of the craft is likely to come as a relief, however, and will help with the forensic analysis that is already underway.
