Interesting link Grey Havoc, that is the first time that I have seen Exomars in that configuration. Let's hope that the lander succeeds this time where Beagle 2 failed.

Keeping Up With TGO

Editor’s note: This week’s blog update comes courtesy of TGO Spacecraft Operations Manager Peter Schmitz at ESA’s ESOC mission control centre in Darmstadt, Germany. The ExoMars Trace Gas Orbiter (TGO) has been conducting a complex and challenging aerobraking campaign since March 2017, using the faint drag of Mars’ upper atmosphere to slow it and lower it into its final science orbit, eliminating the need to have carried along hundreds of kilogrammes of fuel on its journey to the Red Planet. Aerobraking is expected to end around March 2018, after which TGO will perform some additional manoeuvres to achieve its final, near-circular, science orbit of about 400 km altitude.

Proof of life on Mars may be just months away as EU probe begins fly-bys

“If we find traces of methane that are mixed with more complex organic molecules, it will be a strong sign that methane on Mars has a biological source and that it is being produced – or was once produced – by living organisms,” said Mark McCaughrean, senior adviser for science and exploration at the European Space Agency.

“However, if we find it is mixed with gases such as sulphur dioxide, that will suggest its source is geological, not biological. In addition, methane made biologically tends to contain lighter isotopes of the element carbon than methane that is made geologically.”
“We will look at sunlight as it passes through the Martian atmosphere and study how it is absorbed by methane molecules there,” said Håkan Svedhem, the orbiter’s project scientist. “We should be able to detect the presence of the gas to an accuracy of one molecule in every 10 billion molecules.”

If the methane is found to be biological in origin, two scenarios will have to be considered: either long-extinct microbes, which disappeared millions of years ago, have left the methane to seep slowly to the surface – or some very resistant methane-producing organisms still survive underground. “Life could still be clinging on under the Martian surface,” said Svedhem.

However, if the gas is found to be geological in origin, the discovery could still have important implications. On Earth, methane is produced – geologically – by a process known as “serpentinisation” which occurs when olivine, a mineral present on Mars, reacts with water.

“If we do find that methane is produced by geochemical processes on Mars, that will at least indicate that there must be liquid water beneath the planet’s surface – and given that water is crucial to life as we know it, that would be good news for those of us hoping to find living organisms on Mars one day,” said McCaughrean.

Red Planet rover set for extreme environment workout

A representative model of the ExoMars rover that will land on Mars in 2021 is beginning a demanding test campaign that will ensure it can survive the rigours of launch and landing, as well as operations under the environmental conditions of Mars.

An interesting photo Flyaway. One thing though is the ExoMars rover bigger or smaller than NASA's Curiosity rover?

~1/3 the weight. Won't be needing the sky crane landing technique.

Thank's fredymac. Will be interesting to see if it succeeds where Schiaparelli failed.

Please keep in mind as it points out in the article above the landing system will be supplied by Russia.

Rover test: What's it like to ride a rocket to Mars?

So, if you spend a billion euros on a space mission, you better be sure it can survive the rocket ride off Earth.

UK PM Theresa May with ESA Exomars Rover at Farnborough Airshow 2018

The Rt Hon Theresa May, Prime Minister of the UK, examines the ESA ExoMars rover in the Space Zone at the Farnborough International Airshow, accompanied by ESA Director General Jan Wörner, ESA astronaut Tim Peake and Chief Executive of the UK Space Agency Dr Graham Turnock, 16 July 2018.

Wanted: Inspiring name for Europe's 2020 Mars rover

Here's your chance to name the European rover that will go to Mars in 2020.

Currently called ExoMars, the six-wheeled robot needs something a bit more engaging and inspiring for when it lands on the Red Planet.

Astronaut Tim Peake is leading the hunt for a great moniker.

He wants everyone to go to a special website set up for the purpose and enter a suggestion. But don't think "Spacey McSpaceFace" is a goer because this is not an online poll.

All ideas will be put before an expert panel and it is they who will make the final choice.

The last time they try that naming poll in Britain for a polar research vessel
They ended up with RRS Boaty McBoatface...

Finally it became the RRS Sir David Attenborough


for my part label ExoMars as "H.G. Wells: Invader of Mars"

The full parachute system that will help deliver the ExoMars rover and a surface science platform to the martian surface has completed a full-scale high-altitude deployment sequence test, although unexpected damage to the main parachutes occurred.

Meanwhile, the main elements of the descent module hardware, including the heat shield that will protect the lander as it enters the atmosphere of Mars, have been delivered to Thales Alenia Space in Turin, Italy, this week. The European carrier spacecraft that will carry the mission from Earth to Mars, and the Russian landing platform named Kazachok already arrived in Italy earlier this year. The rover, named Rosalind Franklin, is currently being fitted with hardware and its scientific payload in Stevenage, UK. Once fully integrated, the hardware will be tested to ensure it is ready for the journey to space, and operations on Mars.

The May test went largely to plan, with all four chutes deploying in their desired sequence, but both main chutes sustained damage along the way. The same was true during the new round of testing, but ESA notes that it appears that the damage occurred prior to the larger chute fully inflating.

“It is disappointing that the precautionary design adaptations introduced following the anomalies of the last test have not helped us to pass the second test successfully, but as always we remain focused and are working to understand and correct the flaw in order to launch next year,” ESA’s Francois Spoto said in a statement. “We are committed to flying a system that will safely deliver our payload to the surface of Mars in order to conduct its unique science mission.”

So what happens if the next test fails as well (worst case scenario)? Would that mean the rover would miss it's launch window completely, and would ESA have to reschedule the launch for the mid-2020's?

The problems with the parachutes may be worse than has publicly been reported, however. Ars has learned of at least one other parachute failure during testing of the ExoMars lander. Moreover, the agency has yet to conduct even a single successful test of the parachute canopy that is supposed to deploy at supersonic speeds, higher in the Martian atmosphere.

Efforts to obtain a comment from the European Space Agency about this information, or the likelihood of a slip past present 2020 launch date, were unsuccessful. After a spokeswoman with the European Space Agency offered to look into the matter on September, 4, there has been no further response.
