(CNN)The European Space Agency (ESA) has confirmed the Schiaparelli spacecraft, which was expected to land on Mars on Wednesday, has been lost.

During a press conference on Thursday, scientists said that Schiaparelli stopped transmitting around 50 seconds before the expected landing.
The agency suspects something went wrong when the parachute was jettisoned: "The ejection itself appears to have occurred earlier than expected, but analysis is not yet complete," it said in a statement.
ESA's Director General, Jan Wörner, said Schiaparelli's primary role was to test whether they could successfully land a probe on Mars.
"Recording the data during the descent was part of that, and it is important we can learn what happened, in order to prepare for the future," Wörner said.

David Parker, ESA's Director of Human Spaceflight and Robotic Exploration said it's what they wanted from a test.
"We have data coming back that allows us to fully understand the steps that did occur, and why the soft landing did not occur," he said.
The probe was equipped with nine thrusters that were due to be activated for the last 30 seconds to help cushion the landing. But while they were confirmed to have been briefly activated, the agency believes they switched off sooner than expected.
The anxious wait
Scientists with ESA were anxiously waiting for news from Schiaparelli yesterday.
After a high-speed, fiery descent through the Martian atmosphere, scientists at mission control in Darmstadt, Germany, did not get a signal back from the 1,272 pound (577 kilogram) probe.
 
NASA just can't stop rubbing it in with those high res crash site pics

Speaking of rovers, their main problem apparently is the sand clogging up their solar panels.

How hard would it be to put on a cleaning arm on their back that would sweep the dust off them? Is it just not worth it? Or are they simply not meant to last that long?
 
They don't need to use additional equipment to clean the panels, nature always finds a way.

Informative, but I'm not sure I would wager a many million dollar piece of tech on nature's randomness. Perhaps NASA's martian weatherman is just so better than Earth's own ones, but I would rather be safe than sorry with such a precious piece of tech.
 
The NASA rovers were designed to operate for 90 days, the amount of time their engineers figured it would take for dust to render the panels inoperable. Anything after that is gravy. Bear in mind that the Opportunity rover has been operating for 12 years now, Spirit only failed because it became trapped in sand and was still able to continue as a stationary research station for several more years before we lost contact with it, and Curiosity will probably operate for years to come.

I wonder why they don't design them to last that time to begin with. Its not like its easy to get to Mars so they should take the most of what they can with every opportunity.
 
The two biggest limiting factors for space travel are weight and cost. The more something weighs, the more expensive it is to put into the space and the more fuel you need to break once you reach your destination. That's why New Horizons was a fly by mission instead of an orbiter, at the speed it was moving it would have needed an obscene amount of fuel to slow down enough to be put into orbit.

Also bear in mind that Spirit and Opportunity were built as part of the Discovery Program, which was NASA's attempt to create "cheap" missions with high science returns.
