Sounds like they haven't received confirmation that the lander has landed successfully. My hunch is that it hasn't.

Landing stuff on Mars is not easy. The ESA only tried once before - Beagle 2 - and look what happened there.

Good point, the eternal optimist in me.

Beagle landed ok though to be fair

Or the one that went awol due to metric/imperial mishap.

Odd production, they have the runners doing this instead of getting the tea.

We have a 1 hour wait to see if any signal can be picked up.

No, That was NASA's Mars Climate Orbiter.

Beagle 2 is believed to have failed due to an improperly opening solar panel blocking antenna deployment after landing

It wasn't very polished - that's for sure.

More a commentary on failed attempts at Mars. There have been a few.

According to ESA on Twitter the data from Mars Express is inconclusive so they still don't know the status of the lander.

Now waiting for a pass from MRO to see what they can find.

It will be a big shame if the landing didn't go to plan - not sure what that will mean for the planned rover.

"The carrier signal from Schiaparelli recorded by Mars Express abruptly ended shortly before landing, just as the beacon tone received by a ground-based radio telescope in India stopped in real-time earlier today.

Paolo Ferri, head of ESA's mission operations department, just gave an update on the situation.

"We saw the signal through the atmospheric phase -- the descent phase. At a certain point, it stopped," Ferri said. "This was unexpected, but we couldn't conclude anything from that because this very weak signal picked up on the ground was coming from an experimental tool.

"We (waited) for the Mars Express measurement, which was taken in parallel, and it was of the same kind. It was only recording the radio signal. The Mars Express measurement came at 1830 (CEST) and confirmed exactly the same: the signal went through the majority of the descent phase, and it stopped at a certain point that we reckon was before the landing.

"There could be many many reasons for that," Ferri said. "It's clear these are not good signs, but we will need more information."

The newly-arrived Trace Gas Orbiter recorded detailed telemetry broadcast by Schiaparelli -- not just the beacon signal -- and that data should be beamed back to Earth overnight, he said.

"This is fundamental because we should remember that this landing was a test, and as part of the test, you want to know what happened," Ferri said.

Officials hope to share more on what they know about Schiaparelli's fate in a press conference tomorrow at 0800 GMT (4 a.m. EDT)."

My theory - the braking rockets fires asymetrically and flipped it over - which is why the carrier signal ceased abrubtly.

Hopefully the telemetry will rule out it hitting the ground e.g. landing radar altimeter data

Ha, that old chestnut. The answer will be 'maybe'.
It didn't even get that far.

Imagine a lander weighing half a ton that can not only land but then work for years! Oh look, we did that in 1976. https://en.wikipedia.org/wiki/Viking_program. Copy that and put some new gubbins in it.

I'm wondering how much intensive testing ESA have been doing on their landers. I get the feeling it just hasn't been as rigorous as the testing NASA have done on theirs.

As for copying Viking - this lander was not intended to emulate Viking. It was a "proof of technology" device which would only do very limited science. ESA plans to leapfrog Viking and go straight to a Curiosity style rover. I think they just aren't doing their homework.

And just been announced that the parachute opened too early during the descent. That would have caused the chute to shred and disintegrate.

Was it deployed too early or discarded too early? I read it as discarded too early - meaning it didn't do its job for long enough. Plus the rockets only firing for 3 seconds
