NASA Television will provide live coverage of the undocking of ISS Progress 53 from the Zvezda Service Module on the International Space Station beginning at 4:45 a.m. EDT. Undocking is scheduled for 4:58 a.m.
Russian flight controllers will command the resupply ship to undock from Zvezda in a test of an updated rendezvous system that will be used for Progress resupply spacecraft in the future. The new automated system, known as Kurs-NA, will use a single antenna, which will allow four others to be removed. The Kurs-NA-enabled Progress will have only three antennas, half as many as the current versions. Kurs-NA also will use less power, improve safety and possess updated electronics.
