On Nov. 20, mating operations of microsatellites with their separation parts were continued. An Australian scientific satellite called FedSat was mated with its separation part on the 20th.
FedSat and the Whale Ecology Observation Satellite (WEOS), which was mated with its separation part on the previous day, are a 50 cm cube weighing approximately 58 kg.
By contrast, the primary satellite, the Advanced Earth Observing Satellite-II (ADEOS-II) is a 4m x 4m x 6m box weighing about 3.7 tons. Now you can see how small microsatellites are.
ADEOS-II is currently under preparation work for being attached to its separation part.
