Presentations from the 4th Europa Jupiter System Mission (EJSM) Instrument Workshop on July 26-29, 2010 are now available on the [[LINK||PAGE:europajupitersystemmissionejsm:2010ejsminstrumentworkshopproducts||OPFM Website]]. The workshop covered programmatic and technical aspects related to the EJSM mission, more specifically to both spacecraft (JGO and JEO). Among the topics addressed were: Jovian radiation models, the JEO system reliability model, radiation shielding modeling results, and the planned JEO and JGO architectures. In addition, two classes were offered as part of the workshop: a tutorial on the Jovian environments, and Planetary Protection considerations for instrument development. The presentations from this workshop provide relevant information to potential instrument providers who intend to respond to the Announcement of Opportunity (AO) for EJSM instruments, which is currently expected to be released in 2011.

NASA scientists revealed Friday a first-of-its-kind image from space showing reflecting sunlight from a lake on Saturn's largest moon, Titan.
It's the first visual "smoking gun" evidence of liquid on the northern hemisphere of the moon, scientists said, and the first-ever photo from another world showing a "specular reflection" -- which is reflection of light from an extremely smooth surface and in this case, a liquid one.

Dear Colleague, The Europa Jupiter System Mission (EJSM) was recently identified as the first priority mission for the Outer Planet Flagship Mission. EJSM involves the NASA Jupiter Europa Orbiter and ESA Jupiter Ganymede Orbiter. It might also involve other elements, such as a JAXA Magnetospheric Orbiter. In addition to the focus on Europa and Ganymede, substantial Jupiter and Jupiter system science will be conducted.

The Outer Planets Assessment Group (OPAG) met in Tempe, AZ on November 6-7, and was briefed on the two Outer Planet Flagship Mission candidates: Europa Jupiter System Mission (EJSM) and Titan Saturn Systems Mission (TSSM). The NASA and ESA leadership teams were present to make the presentations. Jim Green gave an overview of the Planetary Science Division. It was announced that Bill McKinnon is taking over leadership of OPAG from Fran Bagenal.
Following OPAG the two study teams met to finalize the NASA-ESA Joint Summary Reports on the two flagship concepts, which are to be released on November 15.

The Joint Jupiter Science Definition Team met August 13-14 2008 in Columbia, MD. Primary topics of discussion included new graphic tools to communicate the science concepts for the final report and presentations, tweaking of the science value matrix so that scores reflect the updated ("sweet spot") payload, and specifications for the instruments in the new planning payload. The group also discussed synergistic science to be accomplished with JGO - this will be developed more fully at the next (and final) SDT meeting in London in September.

The fifth meeting of the Titan Saturn System Mission (TSSM) JSDT chaired by Jonathan Lunine and Jean-Pierre Lebreton was conducted in Oxnard California just following the Ices Workshop. This JSDT session focused on finalizing the model orbiter payload and science scenarios for the Titan mission. A variety of issues were addressed, including the optimal strategy for mapping the currently poorly-understood middle atmosphere form 400-800 km altitude. Subgroups dealt with issues such as sensitivity of gravity mapping, radar altimetry versus sounding, and optimal landing sites for the Titan probe. The group also focused on defining payload and landing sites for the in situ elements. Further work by the group will continue to focus on orbiter science scenarios in situ payload.
