The Good news:
Schiaparelli made down to mars
Heatshield worked
Parachute Worked
Landing radar worked
Seperation of Heatshield and Parashute worked.
Landing engines ignited

The Bad news:
Schiaparelli got in problems after Parachute phase and stop transmitting 50 second before landing

ESA and NASA try to communicate with lander by Mars orbiting satellite
MRO will take High Resolution picture of landing site in coming days.

In coming weeks ESA got analyst the 600 MB Data transmit by Schiaparelli to figure out what happen. 

In Mean time NASA got question over social media and press,  on Option to drive the Rover Opportunity to Schiaparelli site...

According to the BBC News site today, the parachute jettisoned far too early.

And not only that but the rockets fired for too short a time.  So it looks like the lander crashed on to the surface of Mars, but ESA are not giving up hope yet.

This was supposed to be a technology demonstrator to validate critical landing hardware prior to the launch of the Exomars rover.  I wonder if there will be delay to conduct a second landing attempt before launching the rover mission?

New's just in from ESA.  They have started to decode the data from Schiaparelli and is being analyzed by the scientists.

Maybe they can get Matt Damon to hike over and take a peek.

There are first (unconfirmed by ESA) information about what happen

Parachute deployment to early and it's jettison much earlier as program
Landing engines ignited and work for 3 seconds not 30 seconds
that means Schiaparelli hit the Mars soil, 50 second earlier as planned and that at far higher speed

seems if this Info is right, MRO will find a new manned made crater on Mars...

For Moment NASA is ask over Social media to send the Rover Opportunity to Schiaparelli impact site.

MRO imaging of the crash site.

Hope ESA goes ahead with the Rover 2020 mission component of ExoMars after the failure of Schiaparelli.

For the people on Twitter asking NASA to just send Opportunity over to look at the landing site, this is easily 40km away from Opportunity's current location.   That's basically the total distance that Opportunity has driven on Mars over the last12 years.

The MRO made picture of Landingsite
Acording NASA the Lander made a 40 by 30 Meter  big Black Spot on Mars surface...

News from Schiaparelli EDM lander
after they look true data, reveal a very disturbing fact
the lander had jettison the heat shield and parachute to early and stop landing  engine after 3 second
because the Computer come to conclusion it was landed !
it start the instrument up an transmit scientific data despite 50 second or 4 km over Mars surface

Schiaparelli EDM lander was build by French/Italian consortium  Thales Alenia Space
It use same Computer build into Trace Gas Orbiter
what imply that same team made software for both
if that true wie have repeat of infamous first flight of Ariane 5 with software of Ariane 4...

Just found this article about the crash site of Schiaparelli on the BBC News Site, on one of the pictures it clearly shows the parachute and rear heat shield.

http://www.bbc.co.uk/news/science-environment-37788444

And this from ESA.

News just in from ESA regarding Schiaparelli.  This is the first time that ESA has acknowledged that the lander crashed onto Mars.  Plus it is in full color.

More news from ESA about the Schiaparelli lander.  It seems that engineers are close to identifying the cause of the crash that destroyed the lander, ESA will have an interim report ready for member states in a fortnight.

This still makes me laugh each time I visit this thread.
