Schiaparelli lander is silent

So the US remains the only country to have successfully landed probes on the surface of Mars.

Russia - zero in 4 attempts*
ESA - zero in 2 attempts
Japan - zero in 1 attempt
US - 9 in 10 attempts **

* one Russian Lander communicated for 14 seconds before failing.

** We still have a rover that landed in 2003 working, so that is 20+ years of working craft on the surface.

NASA seems to have landing on Mars figured out, and perhaps other organizations should just leave getting their scientific instruments on the surface up to NASA.

In this case we lost a really good microscope on the surface of Mars that could have seen bacteria in the soil. That is a huge scientific loss.

On the positive side though the orbiter is fine, and should be able to methane gas in trace amounts, which while being an indicator of life won't be the final proof we are looking for. That microscope could have been.

Also they found the crash site for the lander.

It looks like they figured out what when wrong.

...basically, as Schiaparelli was coming in for touchdown its navigation computer miscalculated its altitude, leading the onboard computer to think that the lander was already safe and on the ground.



... I guess the swoopers here can related to that. The lander was under a good canopy but femur'ed on landing.

Someone should have stressed in ground school how it needs to hold its flare if does it too high.

Sheesh... Next thing you tell me you believe the "moon landing" was genuine too. :S
