The detailed proposal to add Angara-5V into the mix would have to be ready by November 2015. On April 30, Roskosmos issued a directive to GKNPTs Khrunichev, the Angara developer, to prepare a technical proposal to accommodate the man-rated Angara-5V vehicle within the Amur launch complex, which had been under development for Angara-5 and Angara-5P rockets since October 2013 at Russia's new space port in Vostochny. ( 745) According to the head of Roskosmos Igor Komarov, Angara-5V would be developed in cooperation between GKNPTs Khrunichev in Moscow, TsSKB Progress in Samara and RKK Energia in Korolev. In turn, the head of RKK Energia Vladimir Solntsev was quoted as saying that his company would complete a preliminary proposal for the integration of the PTK NP spacecraft with the Angara-5V within six months. On April 22, Yuri Koptev, the head of Scientific and Technical Council at Roskosmos, said that the preliminary proposal for the Angara-5V rocket would be ready by the end of the year. Under most optimistic scenarios in the Russia's long-term space strategy, the circumlunar mission based on Angara-5V vehicles could be accomplished around 2025 and the lunar landing around 2029. For comparison, NASA intended to rely on a single SLS super-heavy launcher to insert its Orion vehicle into the lunar orbit. Even more problematic, four such rockets would be needed to support an expedition to the surface of the Moon. With a projected payload capacity of 37.5 tons, it would take a pair of Angara-5V launchers to place the PTK NP into an orbit around the Moon or into the Earth-Moon Lagrangian points. The Angara would have no problem to insert the PTK NP into the low Earth orbit, however an orbital assembly would be required for practically any deep-space mission, which has been proclaimed as the main purpose of the PTK NP project. Since the agency simultaneously endorsed upgrading the medium-class Angara-5 rocket into an Angara-A5V (or Angara-5V for short) variant, engineers at RKK Energia, the PTK NP developer, attempted to fit the spacecraft and its missions into this much smaller rocket. The decision of the new leadership at Roskosmos at the beginning of 2015 to put off the development of the super-heavy Moon rocket beyond 2025 required finding the new launch vehicle for the new-generation spacecraft. ![]()
