The launch of the Angara A-5 launch vehicle from the Vostochny Cosmodrome has been postponed

Presumably the second attempt will take place in a day

The first launch of the Angara A-5 from the Vostochny Cosmodrome, planned at 12.00, was temporarily canceled for reasons unknown at this time. The rocket was to launch with an Orion upper stage and a test payload.

The rocket should replace the only heavy Russian launch vehicle Proton. It is distinguished from the Proton, which flew on harmful heptyl, because of its environmentally friendly fuel and modularity.

The family of Russian unified Angara launch vehicles with oxygen-kerosene engines includes carriers from light to heavy classes. The lightweight Angara-1.2 with a payload capacity of 3.5 tons (when launching a payload into low Earth orbit (LEO)) was launched in 2014.

The heavy (up to 25 tons for LEO) Angara A-5 first took to the skies also in 2014, and then successfully launched two more, the last time in 2021. All launches were made from the northern Plesetsk cosmodrome in the Arkhangelsk region.

Now we are waiting for the launch from Vostochny, located in the Amur region. The difference between launches from these cosmodromes lies in the launch capability: from Plesetsk, satellites can be launched into lower orbits, from Vostochny – into higher ones. In addition, the launch complex of the cosmodrome in the Far East is designed in such a way that it will allow manned missions to be sent into space in the future.

The developer and manufacturer of the Angara family of rockets is the State Space Research and Production Center named after M.V. Khrunicheva.
