Is there a good thread around here that's something like, "How inexpensive can an interplanetary mission be?"  It's an interesting topic, but deserves its own thread.

Somewhere around here is a slide showing the options for NASA's Mars 2022 orbiter mission. Anybody know where that thread/slide is? I cannot find it.

Mars Polar Lander and Mars Climate Orbiter were both relatively inexpensive.

Specifically, Phobos and Deimos are recommended as targets of opportunity.  Using SEP means that a Mars-focused spacecraft would spend a fair bit of time spiraling in and could make some flybys during that time.

I did, and I seriously hope it happens.  It would be the closest thing, outside of the Phobos encounters by MGS and Mars Express, to a dedicated spacecraft.  The next orbiter looks like it would be studying the moons visually, thermally (including infrared), and even with radar - all of which would vastly improve our understandings of the curious little moons.

There was some recent talk of Phobos in the human spaceflight threads, which in turn lead to mentions of a JAXA mission being considered.  I believe this was the mission in question: http://www.elsi.jp/ja/research/docs/Introduction-PDSR-IntlRv-151102.pdf

Given JAXA has some success with asteroids, not to mention I'm sure they'd wish to make up for the loss of their ill-fated Nozomi, this sounds like a great mission for them.

This appears to be an approved mission (it can be hard to tell for many space agencies).  NASA has issued an AO for an instrument for this mission.  (AO may be preliminary; I can't remember).

Well, you could look at the Indian Mars spacecraft for a start...

That is reassuring to hear, especially after how all 3 proposals in the Discovery selections lost.

The MERLIN Phobos lander almost made the finalist list -- it was judged to be fully qualified (not the term NASA uses) for selection.  Unfortunately, there were seven in this category, and NASA's managers felt they could only manage five finalists.  The other non-selected qualified proposal was the MANTIS asteroid survey.

Regarding the Martian moons and their role in the future, this conference in July may be wise to follow:

Agenda for the Conference on the Exploration of Phobos and Deimos:
Conference on the Exploration of Phobos and Deimos

It looks like the first day will be focusing on the moons' formation along with the Japanese and Russian/ESA missions.  I would love to hear a progress report on both; I wonder how certain the latter is given the uncertainty of the 2nd half of the ExoMars project.

Just over a week away now!  :)

And the Japanese haven't exactly covered themselves in glory with their recent science missions.

Last I heard was that ESA managers will now not put forward the ESA/Roscosmos Phobos sample return mission to ministers in December as planned, which means a decision will be delayed until at least the 2019 CoM.

So leaving just JAXA then?

Exomars is delayed two year, and the UK might leave the EU. Probably better to leave it for when things are settled down and the budget actually available. Specially if they happen to have an actual rover on Mars.

ESA is not an EU organisation. Although the UK will be leaving the EU, there's no suggestion of it leaving ESA.

I'll be at the conference on Monday.

That's grand to hear.  :)

Aside from the previously stated JAXA and ESA/Russia missions, I'm further curious about the NeMO orbiter since that allegedly would flyby the Martian moons en route to low orbit; at this point I'm guessing that will be the most to expect from an American contribution until an actual human expedition, which seems to still be pegged to happen in early missions.

Thinking aloud. There were reportedly discussions on there being an ESA sample capture and preparation module being attached to the 2022 Orbiter as an element in the MSR programme. Additionally ESA could later provide the Earth return vehicle. I also notice the lack of a discussion of the crucial piece of the programme that would likely come from NASA, the Mars Ascent Vehicle.

Would it be feasible to use the MSR infrastructure on a Phobos sample return "dry run"? Instead of the current mission plans a slightly simpler Phobos probe could eject the sample into the path of the 2022 orbiter instead of having to do the Earth return leg as well.  By sharing infrastructure might we get both quicker and cheaper?
