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

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

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

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.

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

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

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.
