WSO/UV is an international space observatory for carrying out WSO/UV is an international space observatory for carrying out astronomical observations in ultraviolet spectral range (91-350 nm). astronomical observations in ultraviolet spectral range (91-350 nm). Such observations can’t be provided from the Earth surface. The Such observations can’t be provided from the Earth surface. The WSO/UV observatory includes the telescope with primary mirrorWSO/UV observatory includes the telescope with primary mirror aperture of 170 cm and scientific astronomical instruments – of 170 cm and scientific astronomical instruments – imaging field cameras and 3 spectrometers (resolving power imaging field cameras and 3 spectrometers (resolving power ranges between 2000 and 60000). Launch of the spacecraft is ranges between 2000 and 60000). Launch of the spacecraft is presently scheduled for 2009.presently scheduled for 2009.

WSO/UV mission model

Telescope: 1.7 m diameter (T-170 Russian model; PSF(550 nm) 0.2 arcsec

Spectrographs: primary 110 - 340 nm. (HIRDES German model) with R5-6 x 104; as well as R 2000 (Long Slit – India?).

Imaging: 115 - 340 nm with quality ~ 0.1- 0.3 arcsec (MCP based Israelian model); 2 UV Imagers: one for max. spatial resolution; one for max. sensitivity; and one Imager for visual domain

The United Nations is also participating, as is the multinational European Space Agency (ESA) on a limited advisory basis.

On participation of India in WSO/UV

• Indian astronomers expressed their interest in participation in the Project. Long Slit Spectrometer’s electronic was suggested as possible contribution of India

• Federal Space Agency has invited ISRO to join the project.

(see letter of Mr.Polishchuk to Dr. G.Madhaven Nair

of September 14, 2004)

• Dr. Narayanan (the Paris based representative of ISRO) participated in the WSO/UV Spectrograph meeting 7-9 December 2004, Tuebingen, Germany. Dr. Narayanan is expected to report in detail on the proceedings of this meeting and convey the conclusions and detailed proposals to ISRO to his Headquarters.

Conclusions

The current meeting seems to be a good opportunity to establish ways for deeper discussions on the mutual interest of Russia and India in the international Project WSO/UV
