The Roscosmos state corporation has announced a competition on development of the space observatory Arch intended for taking high resolution photos of the Sun, the document reads.
The satellite will be intended for examining objects of up to 100 km in size within the range inaccessible for recording from the Earth. In particular, it is expected to help scientists figure out mechanisms of the origin of solar flares.
The observatory will be put to the orbit of not less than 500 km high along with the launch of another spacecraft.
cording to the plan, the draft design of the satellite will be engineered by November, 2017 whereas detailed design documentation to models and trial products will be developed during the period from 2018 to 2020. Satellite models are planned to be made and tested in the same period. In 2019-2023 trial satellites are to be produced, with their complex tests carried out.
The assembly of a flight sample of the Arch satellite and its land experimental development are scheduled for 2021-2024. The launch and flight tests are planned for 2024-2025.
The Arch observatory will become the first Russian satellite for studying the Sun since the failure of the CORONAS-Photon satellite that operated at the orbit from February to November, 2009.
According to the Federal space program for 2016-2025, 2 billion 486 million rubles will be allocated into the Arch project.
