Rassvet (ISS module)
List of ISS modules
Rassvet (Russian Рассвет " Dawn " ) is a research module of the International Space Station ( ISS) and a contribution of the Russian space agency Roskosmos. Other designations are as follows Docking Cargo Module ( DCM, Russian Стыковочно - грузовой модуль - СГМ ) or Mini Research Module 1 (MRM -1 or MIM -1). Rassvet was associated with the shuttle mission STS -132 to the ISS and docked on 18 May 2010 to the Zarya module.
Development
Similarly, the American space agency NASA, the Russian Space Agency Roscosmos is not able to launch all previously planned modules, due to various problems in the construction of the International Space Station. Therefore, in the current manifesto of the start of the research module Nauka is only provided aboard a Proton rocket in 2015. Due to the elimination of another similar module and the installation of the American Leonardo module on the nadir docking of Unity, the adjacent and currently used for transshipment supply ships at nadir Square Zarya would no longer can be controlled safely. As a solution to this problem is Rassvet is a kind of extension and coupling module, so that after the installation still stands a fourth coupling point of Russian design for the coupling of the Soyuz spacecraft and unmanned Progress- vans available.
To speed up the project and the construction of the module was included for the planning and construction on the already completed hull of the formerly planned and no longer needed Science Power Platform. For this purpose, the active coupling adapter type a second passive adapter of type " SSWP G4000 " was " SSWP -M 8000" (suitable for Zvezda, nadir and zenith ) by an active " SSWP G4000 " (fits to Zarya nadir), replaced (according to Progress and Soyuz ) and necessary for the discharge of supply vessels fuel lines installed. Rassvet has eight experimental workstations.
Start and Installation
Since Rassvet in contrast to most other modules Russian design does not have its own engines, was the launch aboard a space shuttle in the mission STS -132 on May 14, 2010. Conversely, the interior was Rasswets for the transport of American equipment reserved. On the outer skin breakpoints for the transport of an airlock, a radiator and spare parts for the European robotic arm ERA are installed beyond. The take-off mass of Rassvet was about 7.9 tons. The installation on the ISS was carried out exactly as the implementation of other modules with the big robot arm, Canadarm2. The entrained air lock for research purposes will be moved after installing Nauka at the free coupling point of MLMs and the radiator mounted on the outer skin.
On 7 December 2009, the new name of the module was known. Rassvet reached on 17 December 2009 with an Antonov An-124 Kennedy Space Center, where it was prepared for the start of the next few months.
Specifications
The empty weight of Rassvet is about 5 tons. It is made of about 6 meters long and made of aluminum alloys. Rassvet has a diameter of 2.35 meters and offers additional 17.4 cubic meters of storage space and 5 jobs for the astronauts.
