Status of Chinese Participation in WSO/UV

1. Status of Chinese Participation in WSO/UV Maohai Huang National Astronomical Observatories, CAS On behalf of Chinese WSO Working Group WIC meeting in Moscow Maohai Huang, NOAC

2. Areas of possible participation • Long Slit Spectrograph • (Large) Ground Stations • Science Operations Center • Launcher and launch service • Tracking, and Mission Operation support • Science WIC meeting in Moscow Maohai Huang, NOAC

3. Long Slit Spectrograph • Proposal sent on March 15, 2006 by NIAOT • Still preliminary • three possible layouts • based on layout by Gersberg and Terebizh (2004) and specifications by Terebizh (2005) • performance study showed good results (0.4”) • Investigated providers of gratings • International collaboration needed • CNSA expressed strong willingness to fund WIC meeting in Moscow Maohai Huang, NOAC

4. Large Ground Stations • A 50meter and a 40meter antenna with backend will be ready for operations in 2007 • Built and operated by National Astronomical Obs., CAS • Can be used for WSO/UV as a major high-speed station WIC meeting in Moscow Maohai Huang, NOAC

5. Science Operations Center • Based on experiences from • participation of ESA’s Herschel Ground Segment • Implementation of the Science Ground Segment of Chinese lunar orbiter project • WSO SOC in China will be capable of supporting observatory-type operations • Proposal handling • Operation planning • Data calibration, archiving, and distribution • Seamless transition between project phases • Help the general astronomical community using WSO WIC meeting in Moscow Maohai Huang, NOAC

6. Launcher and Launch Service • During the China-Russia meeting in Beijing (May 2006) CNSA made official statements: • At the moment CNSA cannot afford to launch WSO/UV all by itself; • It prefers providing commercial launch service, the cost of which is shared by all participating countries. • can provide the part of launch cost that is proportional to china’s share (excluding launch) in WSO/UV.

7. Tracking, and Mission Operation • TT&C and mission operation support from China is largely connected to the provision of launch service • How much could china contribute WSO in this are is uncertain at the moment • Sharing long-term mission operation can still be considered WIC meeting in Moscow Maohai Huang, NOAC

8. science • Key scientific objectives (reionization, extrasolar planets, accretion disks ...) • Definition and Implementation of science road map of WSO • Principles and policies • Definition of road map • Legacy programs • Implementation • Get organized • Make plans • Carry out activities WIC meeting in Moscow Maohai Huang, NOAC

9. What CNSA wants to have in order to fund Chinese WSO/UV participation • Clarify China’s responsibilities and benefits if CNSA is to participate WSO/UV • LSS • Ground Stations • SOC • Etc • this information is needed to put WSO in the high level meeting between Chinese and Russian governments in September 2006.
