Solar System Missions Division ILWS Science in the Solar System Hermann J. Opgenoorth Solar System Missions Division Research and Science Support Department ESA - ESTEC Solar System Missions Division Ulysses Milestones Launch: 6 Oct 1990 by space shuttle Discovery Polar Passes: 1994 (south) / 1995 (north) 2000 (south) / 2001 (north) 2006/7 (south) / 2007/8 (north) End of Prime Mission: 30 Sep 1995 ESA Extensions of Scientific Operations : Jun 1993 SPC: 1 Oct 1995 31 Dec 2001 (6.2 yrs) Jun 2000 SPC: 1 Jan 2002 30 Sep 2004 (2.75 yrs) Feb 2004 SPC: 1 Oct 2004 31 Mar 2008 (3.5 yrs) Solar System Missions Division Ulysses 3rd round over the suns poles Solar System Missions Division SOHO - our eye on the Sun Solar System Missions Division 10 Years of SOHO > 2500 refereed papers by > 2300 scientists > 140 Ph.D. theses > 1000 comets > 2,000,000 command blocks sent to the spacecraft > 100,000,000 exposures MDI > 16 TB in SOHO archive > 85 TB of data served > 275,000,000 web page requests served Solar System Missions Division SOHOs Future Current mission extension until 12/2009 Joint programs with HINODE and STEREO 08/2008: Launch of next-generation SOHO: SDO 2009: cross-calibration of MDI/EIT with SDO > 2010: reduced automated mission (Bonus/Bogart mission) (coronagraphs, TSI,) Solar System Missions Division magnetopause cusp lobe magnetosheath solar wind plasma sheet bow shock Scientific regions visited by Cluster: dayside February Solar System Missions Division magnetopause cusp lobe magnetosheath solar wind plasma sheet bow shock Scientific regions visited by Cluster: nightside September Solar System Missions Division Cluster milestones Cluster I launched by Ariane 5 (failure): 4 June 1996 Cluster II first Launch: 16 July 2000 by Soyuz Fregat (first ESA spacecraft from Baikonour) Second launch: 10 August 2000 by Soyuz Fregat End of Prime Mission: 1 February 2003 First extension: 1 Feb Dec full orbit coverage Cluster active archive startup: Feb nd extension: 1 Jan Dec (mid-term review end 2007) Solar System Missions Division C1,C2,C3 C3,C4 cusp tail C1C1 C2C2 C3C3 C4C4 d Separation distances changed every 6 months 50km! Multiscale ESA Support to Hinode ESA, in sub-contractual collaboration with the Norwegian Space Centre, provides one additional downlink contact to Solar-B for each of the 15 orbits per day This support considerably improves the overall scientific data return and the cadence of observations from the Solar-B mission The European scientific community is catered with processed data through a dedicated Solar B data centre at the University of Oslo MoU with JAXA two European members on the Hinode SWT were appointed this spring. Solar System Missions Division Reasons: Possibility to track all 15 orbits per day Antenna redundancy, and also strong Norwegian interest in the mission. Svalbard Ground Station for Hinode Solar System Missions Division Aurora at Earth Jupiter Saturn Solar System Missions Division Mars plasma environment ASPERA Characterisation of the planetary wind composition (atomic & molecular O + ) away from the solar wind. Solar wind scavenging of the atmosphere down to 270 km altitude, representing a major mechanism in neutral atmospheric degassing and past climate change. Planetary heavy ions accelerated up to very high energies. For the first time, radiation of fast atoms is observed at Mars. Current escape rate of Martian atmosphere (solar minimum).
