** Spektr-R status and RadioAstron science program **

Starting from 10 January 2019 Lavochkin association is unable to establish
communication with the Spektr-R satellite. Within organized control sessions
using the deep space network communication stations in Bear Lakes and Ussurijsk,
the onboard transmitter of low-gain antennas was not activated.

In the same time, there are good news. The RadioAstron tracking stations in
Pushchino (Russia) and Green Bank (USA) continue to detect a tone signal at 8.4
GHz from the Spektr-R 1.5-meter high-gain antenna. Moreover, the closed-loop
system locks in case if the 7.2 GHz tone signal is sent from the ground to the
space telescope. This indirectly indicates that there is power on board the
satellite, and the necessary conditions for maintaining the service and
scientific equipment are provided.

Preliminary estimates indicate that there is a hope to re-establish the
communication. The colleagues from Lavochkin association continue their efforts.

Astronomical observations of RadioAstron within the AO6 science program will
continue as soon as communication is restored.

The mission collects new proposals for the AO7 time period by 21 January 2019 in
order to form a strong science program of the RadioAstron interferometer.

В общем пока дело не безеф, но Юра полон оптимизЪма (хоть и несколько показного). Заявки на 7 наблюдательную сессию, собираются, лавочка обнадеживает.
