There shouldn't have been a KaBoom!
Landing on that planet has not proven easy.
It's not a great day for space watchers. The European Space Agency's Schiaparelli Mars lander may have failed during its descent to the Red Planet. Meanwhile, NASA's Juno spacecraft orbiting Jupiter has gone into "safe mode" unexpectedly. The Schiaparelli lander was carried to Mars from Earth by the ESA's Trace Gas Orbiter ( …
Surely this could have been prevented if we had built another royal yacht Britannia. All those lazy scientists, or 'experts'... I've had enough of them! ...... smartypants
Talking of "experts"as we are, smartypants, and there are certainly more than enough of them littering and loitering practically everywhere and anywhere that has a see and virtual landscapes, here be a long read on what is gone wrong with them when they conspire and aspire to be an elite cult of an executive administrative organ ........ https://www.theguardian.com/business/2016/oct/20/alan-greenspan-cult-of-expert-and-how-it-collapsed ...... lording it with cunning stunts and dodgy deeds done dirt cheap and cheerful.
Latest reports say that the parachutes jettisoned too early and the rockets fired for 4 seconds instead of 30. So at least it won't need to use its drill to get under the Martian surface.
Hopefully Matt Damon's potato crop is not damaged.
The shoestring Beagle actually did a better job of landing, just the B&Q butt hinges on the panels were too stiff so they failed to open.
Seems to be obvious. Or was it the Brits calculating in imperial measures again?
Btw., years of reading online publications have resulted in me automatically scrolling past Twitter screenshots, and now it's compulsive. Would it really be so hard, if you write an article, to actually write it, and not just pass on the source data?

In news elsewhere 'The Brits', or rather their supposed leaders, are intent on totally fucking over the country and doing a blistering job of it so whilst NASA can roger a space craft they have nothing on us.... unless.
Oh, one notes that your user name, Herbert Fruchtl, appears to be a bit foreign. May one enquire what you are doing posting subversive messages to a UK website? Surely you have your own bit of the intertubes to play with and, as you should know, the #IPBill is going to let GCHQ sort you Foreign Johnnies out. God Save Mother Theresa. Rah! Rah! Rah! Tea and Biccies anyone. Jolly Hockey Sticks.
Gosh Toodle Pip.

I stand corrected. Yanks using imperial measures... Brits at least would have had an excuse. It was their empire at some point.
As to your insinuations about my name and certain political developments in this country: I signed up many years ago, in more innocent times, when "This is a tech forum. Why shouldn't I show my real name?" sounded entirely reasonable. The aforementioned developments would be a lot funnier if I didn't have my livelihood tied up on this island. Coming from a country that used to be (and still is) very good at xenophobia, I can tell you that it's not GCHQ that I am worried about. I can come up with a few bad scenarios, but let's not give them ideas.
The Internetworking of Things has moved on quite apace with AI in Cyber Command and Virtual Control of the Quantum Communications Space and IT Networks. Just ask if you dare win win the Office of Cyber Security and Information Assurance [email@example.com] to realise how far behind leaderships in the field the UKGBNI is. It is as well to be aware though that all such sorts of inquiries to those types of office places invariably trigger zero return response and another subject for listing and listening and watching on a no fly list. Such appears to be the very best that they can do with the intelligence and information being made and freely available to them and others too with briefs listening and watching for …… well, Great Game Changer Developments with Sublime Application Project Programming is something to consider is current and real/APT and ACTive and a Model Attacking Defence Force for Collapsed and Collapsing Star Systems/Corrupt Subversive and Perverted Coercive Executive Administrations, which you might like to view as right dodgy inept government of the masses wherever IT and Media is applied and responsible and unaccountable, and that be surely only subversive and coercive, corrupt and perverse whenever viewed through the lenses of paranoia and xenophobia.
When Worlds are in Live Operational Virtual Environments, is everything different from ever before, and that makes the present a future with no past and a Brave New Orderly World Order to make with Global Operating Devices. Do you imagine a Bletchley v2.0 at ITs Work for REST and Play there? Or would such nowadays be a Private Pirate Operation and Renegade Rogue Enterprise which governments buy into with bond issues?
And those be simple enough questions, El Regers, which when ducked when asked of systems, are right royally able and enabled to fcuk you.
Roger that, Camilla Farquhar Farthington Smythe?
Oh, and the above strategy is for all foreigner landers and hard Brexiteers
I sincerely hope the ESA manages to recontact their lander and get it working. Whenever I feel the temptation of pride in NASA's scientific achievements (such as Mars landings), I remember that my professional reference library is full of papers and studies by colleagues from more countries on Earth that I can name.
It was my belief that the initial lander signal loss upon re-entry was due not to it being overwhelmed by "plasma noise", but rather to the plasma blocking signal propagation. A quick web search reveals a paper from the 1960s discussing ways to overcome the plasma blackout which suggests that the main issue is that the plasma strongly *refracts* radio signals so they do not reach the ground.
Any commentards have actual knowledge about this?
TGO and Mars Express successfully recorded transmissions from the EDM.
The following is taken from:-http://www.esa.int/Our_Activities/Space_Science/ExoMars/Schiaparelli_descent_data_decoding_underway
“In terms of the Schiaparelli test module, we have data coming back that allow us to fully understand the steps that did occur, and why the soft landing did not occur,”
and also of note:-
"The thrusters were confirmed to have been briefly activated although it seems likely that they switched off sooner than expected, at an altitude that is still to be determined."
However, I really would not take that as being definitely being the failure event. People will have been up all night analysing the data, and it's easy to miss something in the small hours.
Speaking as an engineer it's *very* positive that everything worked to get the telemetry back from the EDM during the descent. ESA knows a massive amount right now, less than a day after the event, much more than anyone does about the Beagle failure years later. That bodes extremely well for correcting the problem ready for the 2020 EXOMars rover mission.
I really like that way that NASA's Paranoid Programming Practices means that NASA doesn't even trust NASA, and so builds-in some fairly advanced watchdogs.
The 'Belt and Suspenders' approach, backed-up with Duct Tape and heavy-duty (under)pants.
It was though an experimental landing mechanism. The main mission is actually the satellite, the lander was only supposed to operate for a short period and establish if the landing tech actually works. Still, I agree it's a shame.
I hope they got some useful telemetry to unravel where it went wrong.
Come on guys show a little solidarity with your fellow rocket scientists\engineers..
Martian planetary defences do seem to be very efffective, Maybe once Brexit has gone through we could send Michael Gove on a trade mission to bring their tech back to defend the earth. Mind you sending Gove might improve this planet a bit anyway
I think it's just stupid clickbait. Schiaparelli is a test for the real probe which isn't due to land until 2020. In any case, like the recent Space X explosion, it just goes to highlight how difficult some of this stuff is, especially when you're doing it for the first time.
So I guess we'll be reading a lot more over the next few days over any telemetry that could be gathered and which, if any systems, survived the controlled crash.
"So I guess we'll be reading a lot more over the next few days over any telemetry that could be gathered and which, if any systems, survived the controlled crash."
Sorry to be a pedant, but a back of the envelope calculation based on secondary school maths and Martian gravity of 3.711ms-2, a drop time of 19 seconds, and an initial height of 1km indicates an impact speed of around 316km/h or 196mph.
If any systems have survived the crash, then they have exceeded the system requirements for impact velocity, probably by about 2 orders of magnitude.
(Height and time taken from the above referenced BBC article.)
Consider dropping a Mars bar (or confectionary of your choice) from waist height and dropping one from the top of the Shard. The Mars bar dropped at waist height will undergo a similar impact to the planned EDM lander impact after a 2 metre drop in martian gravity.
The Mars bar dropped from the top of the shard will be going *slower* than the Schiparelli lander on impact, partly due to the 3 order of magnitude difference in the thickness of our atmosphere compared to that of Mars. (i.e. the height of the Shard makes up for the difference in the local value of G, but this effect is counteracted by our pesky air.)
I used the term "controlled crash" deliberately because of the thin Martian atmosphere and that landing, at least as we know it on earth, isn't really an option yet.
I think they were testing a new "delivery" method. Success or failure may be determined by the amount of data they get back. Systems could have failed to work properly à la Philae, or everything could have worked well but they just landed in a shit place.
So what if you drop one of those mini-cornetto things, and it falls point-down? How would you calculate the odds that a seagull might swoop down and carry it off?
This is beginning to sound like a plot from Tales of the Unexpected. Suppose I attach the cornetto to a helium balloon, with a slow-burning match suspended beneath both of them on a metal chain, and the cornetto is doused in petrol. Could I use this to murder my unfaithful partner?
That's why I read The Register. I want to know *everything*.
""Hey! What's this thing suddenly coming toward me very fast? Very, very fast. So big and flat and round, it needs a big wide-sounding name like . . . ow . . . ound . . . round . . . ground! That's it! That's a good name- ground!
I wonder if it will be friends with me"
And the rest..... .....was silence"
DNA has an apposite quote once again....
"On ground" planetary exploration / investigation is very, very difficult compared to remote analysis from
And frankly I'm impressed the remote "from above" operations have the success rate they do given the difficulty of the task of getting there & deploying sensors, sending data back (without the worry of landing).
The amazing performance & longevity of the Mars rover craft seems to have led people to think the "on ground" task is far easier than it is.
(full disclosure - relative of mine worked for NASA & has lunar crater named after them)
The lander was supposed to fuck up. That's what the boffins said before hand. It was being used as a test bed for the real lander in 2020.
The fact it probably made a new crater and from above the shiney bits will glint in the sun looking like water won't confuse any of Mars orbiters in the slightest though !!!!
No, the lander was supposed to land and validate the whole technology, and not fail that early. Once again, an ESA lander utterly failed because one or more components didn't work as expected (Huygens too had a computer error that caused the loss of half the data). That means they can't be sure the 2020 lander will work, now. They didn't test a critical part of the technology.
It is clear there are big issues in how ESA validates its systems, and attempting to hide the dust under the carpet is just dangerous, more failures to come, this way.

Really? That doesn't seem at all clear to me. In fact having a test vehicle sounds a lot wanting to validate its systems before trashing even more expensive components. The success rate across all Mars missions thus far leaves a lot to be desired but I can't think of many recent ESA specific failings.
"Retro rockets didn't fire for as long as expected", I suppose at that point the lithobraking came into play and the "crushable structure" became a 100% crumple zone.
But it was a test run and I hope they get the data they need to avoid a rerun with their Armageddon drill probe in 2020. Landing a probe on another planet can't be easy.
Glad to see the main mission is going to plan.
Pints still due.
This plasma wake disrupts signals, therefore it lasted longer than anticipated, the craft didn't deploy the Chute in time, so once it reached it's desired release altitude it let go (early), the rockets were meant to fire for 30secs, but as the ship was travelling faster than expected it reached 2m early and cut the engines, BOOM!
The landing sequence is pre-programmed onto the onboard systems, which are radiation hardened and won't have noticed the plasma. Or at least, we know the on board computer, networking and the radio weren't affected, because they were functioning during entry and we've got the telemetry back.
Some engineers at least will regard their contribution to the lander design to be a resounding success...
When the entry tube/airlock thing blows up wiping out the entire Martian ecology, the explosion is presaged by a few frames of film showing a whitish jet of something coming into the tube.
Is this explicable or just a cock-up/necessary error (if the jet went out of the tube, as it surely would, we film-goers wouldn't see it).?
Damon says he blew up the tube but did he?
