Mini-Research Module 2
is a module of the International Space Station
. It is basically the previously cancelled Russian Docking Compartment 2 (DC2). It is almost identical to Pirs
(which was only designed to be used for 5 years). It will be docked to the Zenith port of the Zvezda module, and will be launched on top of a modified Progress spacecraft on a Soyuz Rocket. MRM1
and MRM2, despite their names, appear to have little or no research capability.
No launch date has been given for this module. The module appears on this updated ISS diagram: http://fotki.yandex.ru/users/rushan-b/view/41888
