Just in case anyone's interested in the contents of the table I did a quick translation. If anything's incorrect don't hesitate to blame me!

If any space agency can pull this mission of it is JAXA, sample returns seem to be their specialty.

Coincidentally last weeks FISO podcast was about a manned mission to Phobo.

A robotic mission would be a prerequisite for this manned mission. If JAXA does it all the better for NASA.

Just checking, but under system components/elec-elec shouldn't it be (electrical propulsion)? The characters look the same as under system components/chem-elec. Thank you for the translation, by the way.

I think you are correct.  電気 means 'electricity'.
The symbol 電 represents a rain cloud with lightning coming out of it,
and appears in words like 'telephone' and 'electric train'.  :)

Apparently some JAXA representatives made a presentation about this mission at a recent COSPAR conference in Brazil. They primarily talked about science goals, but a colleague who was there said that it is a real mission.

I also met somebody who was brought in as a science adviser to them. The Japanese have a history of creating foreign science advisory teams to critique their plans. This person also said that it is a real mission.

I think that this is actually a good idea and a clever one. First, Japan already has experience with sample return, with both H1 and soon H2. So they have the technology and the operational experience. Second, if they do this mission they will do something that nobody else (not NASA, Russia, India or China) has done before. Third, by doing the mission it sets them up to participate in a future NASA-led Mars sample return mission. So there are a lot of positives to doing a Phobos sample return mission.

Sample return seems to becoming something of a speciality for JAXA these days. Scientifically it also sounds a very worthy goal.

Well, NASA has already done sample return (Genesis, Stardust), and will have new capabilities with OSIRIS-REx soon. We don't series produce science spacecraft, so there's no real standardization of hardware except for some sensors. I don't know anything about H2, but I can almost guarantee that it has significant differences compared to H1 because it was built later (and it should have them--H1 was lacking in redundancy). So we have to qualify things when we talk about hardware heritage. This is my sorta roundabout way of saying that their Phobos sample return mission will not be a H2 clone.

But what they have developed is the technology, and an understanding of how the technology works (and what does not work). And they also have developed the operational knowledge. H1 provided a number of great engineering lessons in what not to do. The Japanese know that now, and they won't do it with H2. And they'll gain even more knowledge with H2.

So, yeah, they have this capability and they are smart to apply it to Phobos. I hope they go through with that mission, because it is valuable from a scientific standpoint as well as a political partnership one.

Instead of returning a sample to earth via small capsule what about to cislunar space. Use a Orion mission to pick it up, would allow for a larger sample.

Actually, the sample would likely be smaller. While dispensing with the return capsule, now the spacecraft must carry much more fuel in order to slow down to enter orbit around the Moon. Direct Earth reentry is far more mass-efficient.

Also the cost associated with using an SLS launch to send an Orion capsule to retrieve the sample is prohibitive.

Agreed. There is an interesting proposal for doing this with Orion and a lunar sample called Orion-MoonRise. I rather like that concept, which allows for a much larger sample because Orion would be in the vicinity of the Moon to retrieve something boosted up from it. But coming back from outside the Earth-Moon system you might just as well go into the atmosphere and use that for braking.

Maybe it might be doable with a different launcher & space vehicle.

I wasn't think of dedicated Orion. If NASA was doing Cislunar mission just add pickup of sample to it.
As has been pointed out due to DV changes required, the sample may as well go straight to earth.

The design of the probe will be finished at the end of FY 2016. Launch is still planned for August 2022.

RELEASE 17-090
NASA Selects Instrument for Future International Mission to Martian Moons

NASA has selected a science instrument for an upcoming Japan-led sample return mission to the moons of Mars planned for launch in 2024. The instrument, a sophisticated neutron and gamma-ray spectrograph, will help scientists resolve one of the most enduring mysteries of the Red Planet -- when and how the small moons formed.

The Mars Moons eXploration (MMX) mission is in development by the Japan Aerospace Exploration Agency (JAXA). MMX will visit the two Martian moons, Phobos and Deimos, land on the surface of Phobos, and collect a surface sample. Plans are for the sample to be returned to Earth in 2029. NASA is supporting the development of one of the spacecraft’s suite of seven science instruments.

“Solving the riddle of how Mars’ moons came to be will help us better understand how planets formed around our Sun and, in turn, around other stars,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate (SMD) at Headquarters in Washington. “International partnerships like this provide high-quality science with high- impact return.”

The selected instrument, named MEGANE (pronounced meh-gah-nay, meaning “eyeglasses” in Japanese), will be developed by a team led by David Lawrence of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. MEGANE will give MMX the ability to “see” the elemental composition of Phobos, by measuring the energies of neutrons and gamma-rays emitted from the small moon. The elementary particles are emitted naturally as a result of the high-energy cosmic rays and solar energetic particles that continually strike and penetrate the surface of Phobos.

“With MMX, we hope to understand the origin of the moons of Mars,” said Masaki Fujimoto, director of the department of solar system science in JAXA’s Institute of Space and Aeronautical Sciences. “They may have formed as the result of a large impact on Mars, or they may be captured asteroids of a sort that may have brought a great deal of water to both Mars and Earth.”

MEGANE will be developed under NASA’s Discovery Program, which provides frequent, low-cost access to space using principal investigator-led space science investigations relevant to SMD’s planetary science program.

“We’ll see the composition of the region from which MMX collects its sample,” said Thomas Statler, program scientist for MMX at NASA Headquarters in Washington. “This will help us better understand what we discover in the laboratory when the mission returns the sample to Earth for analysis.”

The Discovery Program is managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama for SMD, which conducts a wide variety of research and scientific exploration programs for Earth studies, space weather, the solar system and universe.

Establishing a thread for JAXA's MMX mission, planned for launch in September 2024.

Mission's website: http://mmx.isas.jaxa.jp/en/index.html
PDF Roadmap of the mission: http://www.isas.jaxa.jp/en/topics/files/MMX170412_EN.pdf

While still in Phase A, I am excited for Japan's mission since it will investigate both moons with emphasis on (as well as sample return from) Phobos.
