Maunakea Spectroscopic Explorer (MSE) Update

(Cassiopeia – Spring/printemps 2017)

The MSE project continues to move ahead. The major focus of the MSE project office in the first quarter of 2017 has been to prepare for an extensive set of subsystem conceptual design reviews in Spain, Canada, Hawaii, and France in the second quarter of 2017. Components to be reviewed are the telescope structure, the enclosure, the high resolution spectrograph, the fibre transmission system, two fibre positioner system concepts, the top end assembly, and the low/moderate resolution spectrograph. A project-wide system conceptual design review and cost review will follow later in 2017.

On Maunakea, the geotechnical firm Fewell have completed drilling sample boreholes beneath CFHT to assess the structural strength of the soil; results are pending. The activity was monitored by ASM Affiliates for any archeological issues; none were found.

The MSE Science Advisory Group has been appointed. The SAG is charged with advising the MSE Project Scientist on any and all aspects of the science-related development of MSE. Its members are: Andrew Hopkins (Australia), Kim Venn and Sarah Gallagher (Canada), Zhao Gongbo and Peng Yingjie (China), Nicolas Martin and Olivier Le Fèvre (France), Brent Tully and Ken Chambers (Hawaii), Gajendra Pandey (India), and Arturo Manchado (Spain). The first charge to the SAG has been to review the MSE Science Requirements Document – available at – and prioritize the science capabilities for first light. Their report is expected for the April 3 meeting of the Management Group.
