I believe it would be attached to the lander itself ( think the MER lander ) - as there are artists impressions that show the lander to not be a dead piece of hardware post-rover departure, but a standalone spacecraft of its own with solar panels etc.

That's right, the lander is supposed to operate (for a year, possibly) on its own after the big rover leaves. This little nanokhod will be tethered and will allow a little bit of extra exploration to be done at the landing site.

Any idea, whether this applies also to the 2016 EDM mission?

No. This is 2018. A Russian lander with a Russian nanorover ("based on a Russian concept"). The 2016 lander is just ESA.

Thanks, Doug & Phil. It's an exciting concept just as a tech demo on its own. Correct me if I'm wrong, but don't think anyone's tried to fly a tethered 'rover' of any sort since the Soviets back in the 70s.

Still wondering when they're gonna nail everything down in CDR, though. Time's starting to get short.

I've found it hard to get information on the Russian station that will operate from the ExoMars 2018 descent stage. The best I've been able to learn is that an announcement to select instruments is expected this year.

The rover sounds cool, but a careful reading of the abstract suggests that it may be one of the "instruments" to be proposed rather than a decided on component.

I'm hoping that the Russian station carries copies of InSight's seismometer and heat probe instruments. Both are European instruments, and that would help selection, and measurements from a second location would be useful. However, deploying them might require a dedicated arm that might be a capability to far for the station.

Yeah, it's a pity! Inside ExoMars - Quarterly Newsletter is abandoned and the Test Campaign Journal no longer updated. The same apparently happened to the BepiColombo Test Campaign Journal.

On Friday Jorge Vago talked about the two missions at the 8th conference on Mars about ExoMars 2016 and 2018. The Russian landing platform is in very early stage and the instruments and equipment is not selected yet. The EDL is already in a good shape and the instruments are selected and the structure is already built. He hinted that there might be a camera on the EDL, so lets wait what they come up with.

It is sad that there is no good updating of the documents for the public, but I see that most of the people who might know what should be written very involved to finish hardware, and in the decision to do hardware or documents I would also do the hardware.

According to this source, ExoMars will "likely" miss the 2018 launch window and if so, would have to wait for a 2020 launch/2021 arrival, and the mission is not guaranteed to occur at all.

At least the 2016 Trace Gas Orbiter launch is holding. I doubt the rover will be canceled, but I wouldn't be surprised to see a minor-to-moderate descoping of the payload in reaction to the funding problems.

Four landing sites for the ESA's Mars rover indicated on a new ESA page dated Oct 1, Mawrth Vallis, Oxia Planum, Hypanis Vallis and Aram Dorsum all close to the equator and all in areas with plenty of signs of flowing water in the early history of the planet.
The choice still to be decided but the text give a hint that Oxia Planum might be a favourite.

Interesting that the candidate landing site maps show landing ellipses for both 2018 and 2020 launches. It's good that they're ready for all contingencies.

I am trying to open the report but the "link to publication" at the ESA website doesn't seem to work for me. Could anyone open and download the report? Thank you.

ADMIN: It downloaded fine from the "link to publication" link for me. The file is 15.1mb and in PDF format. Make sure you have Acrobat available to read the file.

In the context of the discussion of wheel slip observed for MSL, here a video showing a "wheel walking" approach intended to overcome the slip in sandy terrain.
