Open meeting on "SMART-1 coordinated observations and impact", LPSC, 15 March, 12:30-13:30, Marina Plaza Ballroom, South Shore Harbour Resort &Conference Center, League City, Texas Dear colleague, Please find herewith the agenda for the next meeting on coordinated ground based observatories to support SMART-1 measurements and observe the final impact. Please indicate to me your interest for participation and if you want to present material.You are also welcome to send a written contribution in advance or if you cannot attend the meeting. We had a preparatory meeting at ESTEC on 8 March. Preliminary agenda (start 12:30 Marina Plaza Ballroom, LPSC) SMART-1 status and planned operations, Orbit predictions, uncertainties on impact date and time (B.Foing) Community requests for SMART-1 targeted observations Coordinated observations with SMART-1 in March- August - targets imaging - radiometric calibrations - spectrometric observations - merging of SMART-1 and ground based data - ground based detection of SMART-1 spacecraft and laser link experiment - radio detection and VLBI - opportunities for outreach and education Impact predictions (flash, ejecta, probe signatures, exospheric effects, crater) and science/exploration challenges Rehearsal/support of impact observations - SMART-1 observations of previous impact sites - Prior observations of site of impact in July and August - straylight rehearsal Impact observations - thermal infrared imaging of thermal flash - visible/infrared imaging of ejected clouds - spectroscopy - hydrazine flame detection - VLBI observations - accurate coordinates of impact crater - post-characterisation of ejecta - exospheric effects - follow up search for SMART-1 crater (in coordination with future lunar orbiters) Facilities and observing requests, Moon visibility conditions - ESO VLT and La Silla - La Palma (Galileo National Telescope, ING), Tenerife - European continental observatories - US Observatories (Kitt Peak, Palomar, Mc Donald, Lowell, etc..) - Hawaii observatories - Other international observatories Discussion Possible collaborations, Share of tasks Preparation/consolidation of modelling and observing proposals End meeting 13:30 Timeline for future actions and meetings March 15, 12h30: lunch meeting at LPSC dedicated to S1 impact April 3-7: EGU, Vienna, Smart-1 papers in sessions PS1 Exploration, PS2 Moon science (6 April), PS12 impacts (7 April pm) and splinter meeting on "SMART-1 low altitude operations and impact" May 8-12: ESTEC ESLAB on impact craters (discussions with craters and deep impact experts) end June: two delta V hydrazine maneuvers 10 June: Smart-1 perilune below 300 km 20 July: cross tracking SMART-1 perilune below 200 km 27 July: near side 3 Aug: perilune below 150 km 6 Aug: overflight of impact site (coordinated observations and impact observations rehearsal) 14 August: SMART-1 perilune below 100 km 10 - 24 Aug : farside 24 Aug New Moon and SMART-1 on disk edge 3 Sept 0:30 UTC (+-8 hours) intended impact (TBC) 18-22 sept , Berlin Europlanet meeting, including session on SMART-1 results and coordinated observations
