ISS (Nauka)



The uncrewed Russian Multipurpose Laboratory Module (MLM) “Nauka” is safely in orbit following launch at 10:58 a.m. (7:58 p.m. Baikonur time) from the Baikonur Cosmodrome in Kazakhstan.

The MLM deployed its solar arrays and navigational antennas as planned. After Nauka completes eight days in free-flight to allow Russian flight controllers to evaluate its systems, the 43-foot long, 23-ton module will automatically link up to the port on the Earth-facing side of the Russian segment of the International Space Station, which will be vacated by the departure of Pirs. Docking is scheduled for 9:25 a.m. Thursday, July 29, with live coverage beginning at 8:30 a.m.

Nauka will serve as a new science facility, docking port, and spacewalk airlock for future operations. Pirs has been part of the space station since September 2001, functioning as a docking port for Russian visiting spacecraft and an airlock for Russian spacewalks.
