So that’s it for today. ESA will make their next official statements about the Trace Gas Orbiter and the Schiaparelli lander at 9am UK time tomorrow.
For the TGO, everything is peachy. The spacecraft is in the expected orbit and functioning normally. For Schiaparelli things don’t look so good.
The signal was received for a good part of its journey through the Martian atmosphere but was lost before the lander reached the surface. This is confirmed by both the radio telescope tracking from Earth and the Mars Express spacecraft, which was recording the descent from orbit.
Although it would be a disappointment for the landing to fail at the last moment, the most important thing was that it happens now and not in 2020 when ESA send their life-detecting rover to the surface.
So all in all, today was a success. A fantastic new science mission is now in orbit around Mars and the landing test returned invaluable data for the engineers to make the 2020 landing safer.
And that seems like a good place to leave the blog. Thanks for joining us today. It’s been a good one for space exploration.
And with that, ESA brings the press conference to a end.
ESA’s director general Jan Woerner is saying that regardless of what happened to Schiaparelli, this test was a success. He says that they did this to get data about how to land on Mars with European technology - and that is what is downloading from Mars Express right now. Although he refuses to give up hope (he says, “Cross your fingers still”), no one is talking now about the hope of signals being received by Nasa’s MRO spacecraft.
Updated
The detailed diagnostic data from Mars Express is being downloaded now. That will be all received by midnight and then the engineers will work all night to understand what happened. Ferri says that they hope to have the story of what happened to the lander by tomorrow morning.
Updated
ESA’s Paolo Ferri, Head of Mission Operations Department at European Space Operations Centre says that this is not a good sign.
Updated
The Mars Express measurement confirms that the signal from the lander stopped before the landing.
ESA confirm that the signal from the lander stopped unexpectedly.
Now for some news about the lander.
Michel Denis, the ESA ExoMars flight director, says that the Trace Gas Orbiter is definitely in orbit around Mars. It is in a four-day orbit and is working well.
Updated
Here we go. ESA is back online to report on whether they have heard from the Schiaparelli lander.
Good to see that Twitter is doing its best to keep us entertained while we wait.

Today’s landing attempt was a rehearsal for 2020, when ESA plan to put a highly capable rover on the surface of Mars. According to their website:
The ExoMars rover will travel across the Martian surface to search for signs of life. It will collect samples with a drill and analyse them with next-generation instruments. ExoMars will be the first mission to combine the capability to move across the surface and to study Mars at depth.
Given the complexity and expense of the rover, ESA decided to add the Schiaparelli lander to the Trace Gas Orbiter as a test for the technologies that will be required in 2020.
Even if today’s landing failed at the last moment, as looks likely, the data collected will be invaluable in designing a better system to make sure that the rovers gets to the surface in one piece.
Updated
He has a point. Perhaps it’s days like today that show us how much work there is still to be done before we send humans to Mars.
Think about how worried space nerds are right now about #ExoMars, and then imagine a future when real people are at the end of that concern.

While it’s a tense wait to discover the fate of the Schiaparelli lander, ESA are reporting that everything is working well on the Trace Gas Orbiter. This is good because the orbiter is where 99% of the science from this mission is going to come from.
Updated
Clearly something did not go according to plan with the landing. If Schiaparelli does not communicate with Nasa’s MRO spacecraft during the upcoming pass that must be a strong indication of failure.

The Schiaparelli lander is named after the 19th century Italian astronomer Giovanni Schiaparelli. He was born on 14 March 1835, 181 years to the very day before the launch of the mission that bears his name.
During his career he observed Mars and named the major features that could be seen from Earth, calling them “seas” and “continents”. He also thought he saw “channels” on Mars. These are now known to be optical illusions but they sparked a popular idea that they were “canals” built by Martians in a desperate attempt to irrigate their dying world.
Updated
Woerner is still sounding hopeful that Schiaparelli is alive on the surface of Mars. The big test is coming in about one-and-a-half hours when the lander is programmed to talk to Nasa’s Mars Reconnaissance Orbiter.
Updated
Igor Komarov, the director general of Roscosmos, the Russian Space Agency, is speaking in very positive terms about the collaboration between Russia and Europe during this mission. He is looking forward to more collaboration in the future. ESA’s director general Jan Woerner returns the sentiments.

UK astronaut Tim Peake says that the mission is extremely exciting. He is also talking about an experiment he performed during his time in space, when he remotely controlled an experimental rover on Earth from the International Space Station.
Astronauts controlling rovers from the orbit of the moon and Mars is seen as a very likely next step, and a way to link human and robotic exploration of the nearby worlds.
Updated
The Mars Express data from the Schiaparelli lander is being analysed now. There are clear signals of key moments, such as the parachute deployment, so it is clear that the lander passed successfully through the atmosphere but there is still a big question mark over whether it survived the touchdown. But, ESA say it is still too premature to draw conclusions about its fate.
From a vigil-like feeling in ESA’s mission control centre as spacecraft operators watched for the signal to return, there is now back-slapping, cheers and applause. The main science mission is ‘go!’.
The Trace Gas Orbiter is ‘very likely’ in orbit around Mars. The signal has re-appeared at the expected time.
ESA engineers are waiting for the TGO to make contact as it comes out of eclipse from behind Mars. If it phones home at close to the calculated time this will be an excellent indicator that it is in the correct orbit around Mars.
The ESA flight dynamics team will calculate the Trace Gas Orbiter’s orbit around Mars as soon as the signal is received in a few minutes time.

We are now just minutes away from discovering whether the Trace Gas Orbiter went into orbit around Mars successfully.
Mars is a difficult planet to land on because of a combination of factors. Firstly, it is a large planet and so has a strong pull of gravity that must be counteracted using retrorockets or parachutes. However: secondly, Mars has only a thin atmosphere and so heatshields and parachutes have only a limited effect.
The Trace Gas Orbiter is where the vast majority of the science of this mission was always designed to come from. It will orbit Mars for years looking at the atmosphere in more detail than anyone has ever done before.
Of particular interest is whether methane is found in Mars’s atmosphere. In 2003, Mars Express made a tentative detection of the gas, which sparked excitement because methane is a short-lived gas, and on Earth it is produced mainly by life forms.
In 2014, Nasa’s Curiosity rover also detected whiffs of the gas. This increased speculation that perhaps there were microbial communities still alive on Mars, producing the gas. However, there is also the chance that the methane is produced by geological processes.
The TGO is designed to help explore these different possibilities.
Updated
Even if the lander doesn’t work as planned, valuable lessons will be learnt from the attempt. The Mars Express spacecraft recorded data from Schiaparelli all the way down to the surface. That data is being transmitted back to Earth now for analysis. It is the equivalent of the data recorded by an aircraft’s ‘black box’ flight recorder.
Denis also confirms that the Schiaparelli data from Mars Express is being downlinked now. About half an hour from now, they hope to be able to say something about the lander’s fate. A key moment will then occur in about a hour from now when Schiaparelli is designed to wake up and send signals to Nasa’s Mars Reconnaissance Orbiter. It’s still all to play for!
Updated
Michel Denis says he is very confident that the TGO completed its orbit insertion manoeuvre. Confirmation should come in about 30 minutes.
This could be a reason for optimism. If the size of the Schiaparelli landing recording is consistent with the expected size it would seem to indicate that Schiaparelli worked as expected down to the surface. But the big question is: did it survive the landing?

Mars landing: what we know so far
- The Schiaparelli lander has fallen silent during the last moments of its decent to Mars.
- It was being tracked from Earth by the Giant Metrewave Radio Telescope (GMRT), located in Pune, India.
- During its descent through the atmosphere, the GMRT saw several “jumps” in the signal that correspond to key events taking place correctly on the lander, such as the parachute being deployed.
- Flight controllers at ESA are refusing to “jump to conclusions”, preferring to wait until they can analyse the data recorded by the Mars Express spacecraft, which was in detailed communication with Schiaparelli all the way to the surface.
- The Mars Express data is being returned to Earth now and the analysis is expected to take several hours.
- Meanwhile, the Trace Gas Orbiter has been firing its engine to reduce its speed from 12,000km/h to 5000km/h.
- The orbiter is now in eclipse behind Mars but will be back in contact with Earth at around 17:30 UK time.
- Once contact is re-established, the flight dynamics team can confirm whether TGO is now in orbit around Mars.
Updated
There can be no doubt that Nasa has dominated Mars exploration. To date they are the only space agency to successfully land and return science from Mars.
The Soviets were the first to receive signals from the surface on Mars in December 1971. Their Mars 3 mission landed on the surface but worked for just 14.5 seconds, sending back a static filled image that defies analysis to this day.
Worried that the spacecraft may have been swallowed by Martian quicksand, Nasa programmed their 1976 Viking mission to take an image of the landing pads as soon as they touched down. The image of footpad 3 is therefore the first clear image to be taken from the surface of Mars.
Since then, Nasa have successfully landed on Mars six more time.
ESA’s 2003 Beagle 2 lander never phoned home, and so was presumed to have crashed. However, in 2015 it was discovered to have landed successfully, but not deployed its antenna.
Updated
Meanwhile high above Mars, the Trace Gas Orbiter is still firing its main engine to be captured by Mars’s gravity. The spacecraft is now behind the planet and so out of contact with the ground but this was expected. It will be in view of Earth again at around 17:30 UK time, when flight controllers will be able to confirm whether or not it achieved orbit.
So, it looks like we are in this for the long haul. Using the Indian radio telescope was always a long shot and something of an experiment - the Schiaparelli lander was never designed to transmit directly to Earth.
The main route to confirming the landing was always designed to be by analysing the data recorded by the Mars Express spacecraft. That orbiter is now getting ready to point to Earth, rather than at the Schiaparelli lander, and relay its recordings to Earth, where they will be analysed.
Updated
Andrea Accomazzo saying that finding the signal in an “ocean” of noise is not going to be quick. It is going to take hours, not minutes, to determine if the mission landed successfully.
Updated
Still no signal it seems from the surface of Mars. ESA are saying “let’s not jump to conclusions”. This might not mean disaster, but it looks increasingly as if we will have to wait for the main recordings from Mars Express to be sent back to Earth and analysed by the flight dynamics team.
Updated
The mission flight director is in conversation with the Head of the Communication Office at ESA’s Operations Centre (ESOC). Hopefully some official news will be coming soon.
Still waiting for a signal to confirm successful touch down. Schiaparelli was designed to drop the final few metres to the surface. A “crushable structure” rather like the crumple zones on a car was designed to absorb the final shock of touchdown.
Updated
ESA report that they are still waiting for a touchdown signal.
All the indications are good so far, but there is clearly tension in the ESA main control room as we wait for more signals from Schiaparelli to say what is going on.
The Schiaparelli decent module uses a heatshield, a parachute and thrusters to stop itself from crashing into the surface.
Good news so far.

Schiaparelli is descending through the Martian atmosphere. Very tense faces in ESA mission control.
Andrea Accomazzo, ESA Spacecraft Operations Manager, says that the atmosphere at ESA’s control centre is “very tense” as they wait for signals.

But it takes just under 10 minutes for the signals to travel across space and be received on Earth.

We are just minutes from the Schiaparelli lander hitting the atmosphere of Mars. The critical part of this mission – the entry, descent and landing (EDM) – is now very close.
Nasa call the entry, descent and landing “seven minutes of terror” because of all the things that can go wrong. ESA are playing it calmer. Michel Denis, ESA ExoMars flight director said earlier that he just thinks of it as “waiting”.

This is all you need to see to know that your spacecraft is alive.

The Trace Gas Orbiter and Schiaparelli were launched on 14 March this year from Kazakhstan. Russia became partners in the mission after Nasa pulled out of the collaboration in the wake of the credit crunch.

Can you call a headlong plunge into the Martian atmosphere “falling gently”? I guess you can if you’re ESA and this is just what you do. :)

This is where it is all happening today: ESA’s main control room in Darmstadt, Germany. This is where flight controllers are currently waiting and monitoring both the TGO and Schiaparelli to confirm orbit insertion and landing.
Updated
The Trace Gas Orbiter will be firing its main thruster for 139 minutes to slow itself down and be captured by Mars. The spacecraft will be back in contact with Earth around 5:30pm UK time to report whether or not it successfully entered orbit.
Updated
ESA’s previous Mars mission, Mars Express, is now recording signals from the Schiaparelli lander as it heads for the surface of Mars. The recording will be transmitted back to Earth and ready for analysis roughly one-and-a -half hours after the landing.
Updated
The Trace Gas Orbiter continues to burn its engine to lose speed and be captured by the gravity of Mars. ESA report that so far, this is going well.
This is where the Schiaparelli module is heading this afternoon. The shaded orange ellipse is the target area. It is part of a plain on Mars called Meridiani Planum. The ellipse is 100km x 15km.
The region has been well studied from orbit and shows good evidence of once having been covered in water.
Here’s what will be happening on Mars during today’s landing attempt.
Referring to the simultaneous landing of Schiaparelli and orbit insertion of the Trace Gas Orbiter, ESA’s ExoMars flight director Michel Denis has just said, “This is the European way: do two things at a time and be successful at both!”
It’s a bit early to say that, but you have to admire the confidence.
Updated
Good news, the radio telescope in Pune, India, has picked up the Schiaparelli signal. The lander is alive and functioning, and on its final approach to Mars.
.@ESA_EDM ACQUISITION OF SIGNAL at #GMRT! A faint trace on the screen shows us that @ESA_EDM has woken up on schedule #ExoMars
— ESA Operations (@esaoperations) October 19, 2016
So far, there is no clear signal from the GMRT from Schiaparelli. ESA say they are not concerned. Picking up the signal from Earth was always an outside chance. The lander will be tracked from the spacecraft in orbit around Mars as original planned.
ESA are now hoping to pick up the Schiaparelli lander’s faint radio beacon using the Giant Metrewave Radio Telescope (GMRT) in Pune, India. Schiaparelli was not designed to transmit directly back to Earth, it was supposed to communicate only through the other spacecraft at Mars, so the GMRT may not hear it. But it would be good if it does!
The Trace Gas Orbiter, which carried the Schiaparelli lander, is one of the largest satellites to be sent to Mars.
“It is an order of magnitude step up in scientific quality. The sensing of the trace gases is a real fundamental step forward in terms of the global exploration of Mars. It is a big scientific payload. It’s more like taking the atmospheric instruments that we have on Earth Observation satellites, and taking them all the way to Mars and putting them in orbit around Mars,” says David Parker, ESA’s director of human spaceflight and robotic exploration.
Designed to sniff out methane in the Martian atmosphere, it could put us on the trail of whether there is life on Mars.
Updated
Here we go! The Mars Orbit Insertion Manoeuvre is taking place right now. The Trace Gas Orbiter has arrived at Mars travelling at 12,000km/hour. It needs to shed almost half that speed to be captured by Mars’s gravity. This engine burn is happening now and everything is looking good. This manoeuvre is separate from the Schiaparelli landing.
Updated
The animation shows this afternoon’s trajectory of ESA’s spacecraft. Schiaparelli heads directly for the planet, while its ‘mothership’ the Trace Gas Orbiter goes into orbit around Mars to begin its scientific mission. The orbit of ESA’s previous mission, Mars Express, is also shown.
This afternoon the European Space Agency (ESA) will make a landing attempt on Mars. The Schiaparelli module is due to touch down at 3:48 UK time, although confirmation that all has gone well is likely to take several hours.
This is an important moment for ESA. Their previous landing attempt on Mars, back in 2003 with the UK-led Beagle 2 lander did not go as well as hoped. Although the lander reached the surface safely it failed to transmit anything back to Earth.
Today’s landing is designed to show that ESA can now land safely on Mars, in preparation for an ambitious rover mission in 2020 that will look for past or present life on Mars.
So, it’s all to play for! Whatever happens today it is going to be an important one for ESA and the world’s exploration of Mars.
We’ll be covering the events as they happen live.
