The first of the Planet Lab Dove CubeSats were deployed from the ISS on February 11, 2014 about 0831 UT
According to NanoRacks the deployment of the second batch of CubeSats from the International Space Station (ISS) will commence at 1700 UT on Tuesday, February 25, 2014. The CubeSats deployments were streamed live at http://m.ustream.tv/channel/live-iss-stream
ISS Kibo Japanese Experiment Module (JEM)
Earlier this month astronaut Koichi Wakata KC5ZTA successfully deployed the first part of the Flock-1 constellation comprising 16 Dove 3U CubeSats developed by Planet Labs. The remaining 12 Dove CubeSats along with the amateur radio CubeSats LituanicaSat-1, LitSat-1, ArduSat-2, UAPSat-1 and the 915 MHz SkyCube should be deployed in the second batch.
The amateur radio CubeSats may be deployed on Friday, February 28 at 0730 UT. Another amateur radio CubeSat the Peruvian Chasqui 1 was sent to the ISS on February 5, 2014. It is not yet clear if this will also be deployed on Feb. 28.
Eight NanoRacks deployers are installed on the Multi-Purpose Experiment Platform (MPEP). Each deployer has a capacity of 6U and so can hold up to six 1U CubeSats or two 3U CubeSats. They are carried by Japanese Experiment Module-Remote Manipulator System (JEM-RMS).
Two 3U CubeSats (6U total) can be deployed every one to two orbits to prevent collisions. For the first batch of Flock-1 CubeSats about two deployments took place each day.
