The assembly of the Soyuz-2.1a rocket has been completed at the Vostochny Cosmodrome, which on May 27 at 00:14:51 will send the Kondor-FKA No. 1 radar Earth remote sensing satellite into orbit. Not only is the satellite the first of its kind, but this launch also has another feature - the use of naphthyl.
«This will be the second launch of the Soyuz-2 family rocket entirely on a new and highly environmentally friendly fuel - naphthyl - and the first for the Soyuz-2.1a modification. Naphthyl is an environmentally friendly type of hydrocarbon fuel with the use of polymer additives. Its advantages are reducing harmful emissions and a noticeable increase in the mass of the payload put into orbit», Roscosmos writes.
As for Kondor-FKA, this spacecraft is designed for round-the-clock all-weather radar remote sensing of the Earth in medium and high resolutions.
