Nice list of instruments. Doing all that w/o a scan platform like Cassini?

That's something that would be interesting to know - turning a spacecraft with big solar arrays is more difficult than turning a spacecraft like Cassini. It would also be extremely interesting to know something about the instrument specs.

anybody knows the difference between the Gravity & Geophysics of Jupiter and Galilean Moons and the Planetary Radio Interferometer & Doppler experiments?
they look like both radio tracking experiments

For PRIDE it says there is no spacecraft component, just the VLBI, so maybe 3GM is only the spacecraft component?

I do miss a micrometeoroid-experiment. SUDA (SUrface Dust Analyser) not onboard? huh.gif

Does anyone know what the Irish involvement is? The ESA press release gives no details and they haven't replied to my query yet.

Not sure about Irish part, but I can provide info about Czech involvement if someone's interested.
Google translation of recent Czech Space Office announcement.

A Russian Ganymede lander in addition to the European JUICE orbiter ?

More detailed information on the instruments:

http://sci.esa.int/science-e/www/object/in...fobjectid=50073

In particular, the camera (JANUS) has a field of view of 1.3 degrees and carries 13 filters. This is a bigger field of view than the 0.3 degrees discussed earlier in this thread but the size in pixels is not shown (I'd love to see more detailed information on the camera specs). 2048x2048 wouldn't surprise me and would result in a resolution comparable to the Galileo camera. There's no mention of a wide angle camera and there's no information on whether pushbroom imaging is possible. One good thing about 1.3 vs. 0.3 is that global scale mosaics of Jupiter would have been a problem with a 0.3 FOV (huge number frames).

MAJIS is also a very interesting instrument - a hyperspectral imager from 0.4 to 5.7 microns with a top resolution of ~100 km for Jupiter and 25 m for Ganymede.

I found some additional information on the imaging experiment (JANUS) here:

http://meetingorganizer.copernicus.org/EPS...PSC2013-506.pdf

Not much new information on the camera itself though. The most interesting thing to me is that it has WAC imaging capabilities in addition to the 1.3 field of view and it's a framing camera. Reading between the lines it seems to me that the image size in pixels is ~2048x2048. This is not explicitly mentioned but the resolution numbers seem to imply something like this.

However, there is considerable information on the planned imaging coverage. In particular, compared to Galileo the coverage of Europa looks impressive to me since there are only two close Europa flybys.

More detailed information on the JUICE instruments is gradually becoming available. I recently found this interesting PDF document from the 45th LPSC (2014) conference:

http://www.hou.usra.edu/meetings/lpsc2014/pdf/2094.pdf

The most interesting new information to me is a list of the JANUS filters:

Airbus has won the 350.8 mln euro contract to build JUICE over Thales Alenia's competition.
