Angara in Vostochny


Vostochny's processing area features new architecture

At the future Russian space center in Vostochny, all preparations of rockets and spacecraft before their roll out to the launch pad will be conducted at a special facility identified as Technical Area, or Tekhnicheskaya Pozitsiya, TP, located at Site 2. Although it has been a traditional feature for many launch sites around the world, the processing facility at Vostochny was conceived to have a truly innovative architecture.

The rocket and spacecraft preparation facility

Traditionally, Russian launch sites had separate processing and assembly facilities for each type of rocket. In many cases, a full complement of support infrastructure would have to be built even for individual launch pads. These large and expensive facilities were often sprawling over a considerable area, all requiring their own roads, communications lines, personnel and residential areas. In contrast, for Vostochny, developers at OAO Ipromashprom, (the main architectural contractor on the project), designed a single centralized processing and assembly hub, which would consolidate all preparation activities of the space center. Rockets of various sizes and their payloads would still be prepared inside their custom-built work sites, or modules, however they would all be located next to each other and linked by a single hallway known as "transborder gallery". Such an innovative solution promised to minimize the volume of each individual building, eliminate the duplication of support infrastructure, keep all spacecraft preparation activities under one roof and enable future expansion of the facility.

Rocket assembly building, MIK RN


The main building of the processing complex, MIK RN, is dedicated to the assembly of launch vehicles. The main assembly hall has an area of 9,000 square meters. It is equipped with with a pair of dual cranes spanning 40-meter width of the facility and capable of lifting up to 100 tons each. The cranes move just below the ceiling of the building 27 meters above the floor. On the floor, the building has a total of 510 meters of rail lines.

On one end, the processing building is connected to the rocket stage storage facility, on another to the transborder gallery. The main hall of the building is flanked by several floors of administrative, support and testing rooms.

According to Spetsstroi, the main contractor on the building, the ventilation system inside the facility provided R9-class air for the clean-room environment inside the building with a total processed air volume of one million cubic meters per hour. The climate-control system was designed to to maintain temperature from 18 to 25 degrees C and humidity of 80 percent, Spetstroi said.

Spacecraft processing building, MIK KA


The spacecraft processing building has specialized work sites for processing and handling various satellites, upper stages and payload sections integrated under the payload fairing. The facility was equipped with high level of climate control and filtration systems to ensure clean environment for sensitive sensors onboard the spacecraft.

A pair of 50-ton cranes built in St. Petersburg was located 34 meters above the floor and span 42 meters.

The main assembly hall of the building was flanked by seven floors of administrative and support rooms.

Fueling and neutralization station, ZNS

On the opposite end from the transborder gallery, the spacecraft processing building is flanked by the the ZNS station. It was designed specifically for fueling of the spacecraft prior to their mating with the launch vehicles, which required to include this facility into the first phase of construction to be completed before the end of 2015. In addition to storage for hazardous propellants, the ZNS building also included means for collecting and neutralization of industrial waste and hazardous vapors. Floors of the three-story, climate-controlled facility were paved with special acid-resistant tiles.

Transborder gallery


The main transfer hallway (transborder gallery) also designated GP-12 and developed at KB Motor had a total area of 10,000 square meters. It would sport a pair of giant movable platforms or "transborders." Weighing 200-ton and measuring 6 by 28 meters, this truss structures would shuttle back and forth along rail tracks on four dual bogies. After a spacecraft or a rocket component had completed the processing inside its work site, it would roll onto the platform, which would then transfer it to the main assembly hall for final integration.

According to the original plans approved in 2010, the half-a-kilometer-long transfer hallway would be connected to the south sides of four processing buildings:

  • The satellite, upper stage and payload section assembly building, or MIK KA, RB and KGCh;
  • The manned spacecraft processing complex, MIK TK PPTS;
  • The assembly and maintenance complex, MPK, for the PTK NP spacecraft and its launch and docking module, SSB;
  • The launch vehicle assembly building;

In addition, the same transfer hallway was to be connected to the north sides of five support buildings with storage rooms, fueling and power stations.

However, when the development of the processing complex in Vostochny finally reached the construction phase in May 2012, visuals gleaned from reports in the official media revealed that only around a half of the original design had survived the reality check. According to a statement from the Spetsstroi contractor, a total of 24 buildings and facilities were included in the first phase of the general plan.

Scheduled for completion at the end of 2015, the scaled down complex still sported a cavernous 180 by 60-meter launch vehicle assembly building. It was originally intended for Rus-M rockets, but after the cancellation of the project in 2011, the facility was re-purposed for a smaller Soyuz-2 and Soyuz-2-1v launch vehicles. The rocket assembly building was flanked by a spacecraft processing facility, which would now house work sites for unmanned satellites.

Most importantly, the innovative centralized architecture of the overall complex has been retained, with the foundation of the transfer hallway clearly visible on satellite photos of the construction site in 2012. Publicly available blueprints also hinted at the plans to expand the transfer hallway westwards in order to accommodate a new processing area for the Angara family of rockets in the second phase of development in Vostochny. Optimistic plans of 2012 apparently aimed to bring Angara to Vostochny as early as 2018 to carry manned missions from the site.

Support facilities

Along with main processing complex for rockets and spacecraft, Site 2 would be home to various support facilities such as a fire station, a complex belonging to the Ministry of Emergency Situations and a propellant storage.

Roskosmos scheduled the preliminary design for the support facilities to take place from May 2011 to March 2012. Proposed support infrastructure included:

  • Fueling and neutralization station, ZNS;
  • Oxygen and nitrogen production plant, KAZ;
  • Physics and chemistry lab, FKhL;
  • Rocket propellant storage complex and means of its transportation, KKh KRT ST.

The project relied on already completed designs for the Rus-M rocket. The construction was to be split into two phases: the first stage with a completion date in 2015 and a second stage with a completion in 2018.

Construction activities at Site 2

The construction at Site 2 started roughly in parallel with the work at the Soyuz launch pad in the spring and summer 2012. According to the official press, foundations for a total of 15 facilities of the technical complex had to be finished by the end of 2012. Signs posted at the construction site of the processing complex quoted completion dates as September and December 2015.

Residential area

Simultaneously, construction was picking up at various secondary locations beyond Site 2. By the beginning of 2013, Dalspetsstroi (the main local contractor), reported the completion of renovation at five formers barracks capable of accommodating more than 1,000 workers.

Ledyanaya train station

The Ledyanaya train station at the junction between the main railway artery of the space center and the federal railway line was also under renovation, along with the construction of power lines, railway and automobile roads. Workers also broke ground at the industrial support zone located southeast of Site 2.
