Exo. Mars: a unique mission ! Exo. Mars 2020 constitutes a totally unique science mission, with the capability to address questions which were not even raised when the mission was conceived and designed: in particular with the fundamental change of paradigm presently being built, with respect to the question of unicity of the Earth (what time/space scale ? ) and of the life it harbors. The mere question of “habitability” is severely challenged and re-visited, while programs to search for life beyond the solar system are decided.

The mere question of “habitability” is severely challenged and re-visited, while programs to search for life beyond the solar system are decided. Exo. Mars 2020 uniqueness resides in particular in its capability 1. to decipher the composition of Martian samples, deeply drilled, down their microscopic scale, sequentially by three instruments spatially coregistered; 2. to identify the sample context by a unique suite of instruments mounted on the rover, and 3. to explore a site known to have (uniquely in the entire solar system) preserved the witness of the processes which sequentially operated over the first billion years of its history, during which Mars (and Earth !) might have hosted an “habitable” environment.
Exo. Mars: a unique mission ! The Micr. Omega team (through OMEGA and CRISM primarily) has played a key role within the LSS process. The entire ESWT should be involved at least to endorse the final proposed selection (November 8 and 9).
Exo. Mars: a unique mission ! The Micr. Omega team (through OMEGA and CRISM primarily) has played a key role within the LSS process. The entire ESWT should be involved at least to endorse the final proposed selection (November 8 and 9). Exo. Mars 2020 is timely, to characterize samples with distinct (than NASA Mars 2020) means (e. g. down to its microscopic scale, from deep subsurface, well characterized…), thus offering to contribute to the sample selection Mars 2020 will perform in caching samples for MSR: cooperative activities between Exo. Mars 2020 and Mars 2020 are more than required. I made proposals in this direction at the recent MEPAG meeting, suggesting in particular an exchange of scientists between the two teams to envision coupled operations, scientific investigations, joined decisions on what samples to be cached etc… The reaction was… moderate… A pro-active decision from Exo. Mars, towards our Project Scientist, to interact with Mars 2020 Project Scientist, should be strongly encouraged at this ESWT.

Fingerpointing the “wanted murder”, as if one had decided that the mission cannot be timely achieved, is not the optimized way to create a spirit of co-responsible partnership, towards jointly elaborating the best workaround solutions for the success of Exo. Mars.
Micr. Omega / Exo. Mars Development Status The Industry has a key responsibility in this “contractually-based” behavior, treating P/L as customers, contrasting with the spirit of partnership key for such missions. The demonstration that Exo. Mars cannot be achieved timely is a (unexpected dream) gift offered to those searching to transfer such optional programs to EU.

The demonstration that Exo. Mars cannot be achieved timely is a (unexpected dream) gift offered to those searching to transfer such optional programs to EU. We, scientists, have indeed a responsibility in the severe delays triggered by severe technical issues: the (scientifically required) level of performances at mission start was non realistic, and should have been descoped, when it became obvious that it was not achievable. ESA should not have followed Industry interest to maintain them (thus asking for more time (and money!) to solve them. Years ago already some of us proposed to sit and address this issue, in three directions: 1. accept/decide to get at Mars with the system and P/L as is, even with a descoped level of performances (e. g. at UCZ level !); 2. re-shuffle the EQM/FM/FS AIT plans for a 2020 launch, and reprioritize their sequencing. Was never accepted but : still on the table !
