Science Power Platform

The Science Power Platform (SPP; Russian: Научно-Энергетическая Платформа, Sci-Energy Platform, also known by Russian initialism NEP) was a planned Russian element of the International Space Station (ISS) that was intended to be delivered to the ISS by a Russian Proton rocket or Zenit rocket (it was originally designed to be part of Mir-2) but was shifted to launch by Space Shuttle as part as a tradeoff agreement on other parts of the ISS.

It would have provided additional power for the ISS as well as roll axis control capability for the orbital facility.

If the Science Power Platform had been delivered to the ISS, it would have been attached to the zenith port of Zvezda, a position currently occupied by Poisk.

The SPP's robotic arm (European Robotic Arm) was still added and is currently a part of the station, and launched together with the Russian Nauka Multipurpose Laboratory Module on 21 July 2021, after many delays.

The already-made pressurised hull of a static test article for this component is now being used for the Russian Mini Research Module 1, which launched on STS-132 in 2010.
