and Russian-built Zarya, which means Sunrise when translated to
English, is a U.S. component of the station although it will be
built and launched by Russia. The module was built by the
Khrunichev State Research and Production Space Center (KhSC) in
Moscow under a subcontract to The Boeing Co. for NASA. Only weeks
after the Zarya reaches orbit, the Space Shuttle Endeavour will
rendezvous with it and attach a U.S.-built connecting module
called Node 1. The Zarya module will provide orientation control,
communications and electrical power attached to the p./img/assive Node
1 for several months while the station awaits launch of the third
component, a Russian-provided crew living quarters and early
station core known as the Service Module. The Service Module will
enhance or replace many functions of the Zarya. Later in the
station's assly sequence, the Zarya module will be used
primarily for its storage capacity and external fuel tanks.
control module, also known by the technical term Functional
Cargo Block and the Russian acronym FGB, will be the first
component launched for the International Space Station and
provide the station's initial propulsion and power. The
42,600-pound pressurized module is scheduled to be launched on a
Russian Proton rocket in November 1998.
The Zarya module is 41.2 feet long and 13.5 feet wide at its
widest point. It has an operational lifetime of at least 15
years. Its solar arrays and six nickel-cadmium batteries can
provide an average of 3 kilowatts of electrical power. Using the
Russian Kurs system, the Zarya will perform an automated and
remotely piloted rendezvous and docking with the Service Module
in orbit. Its side docking ports will accommodate Russian Soyuz
piloted spacecraft and unpiloted Progress resupply spacecraft.
Each of the two solar arrays is 35 feet long and 11 feet wide.
The module's 16 fuel tanks combined can hold more than 6 tons of
propellant. The attitude control system for the module includes
24 large steering jets and 12 small steering jets. Two large
engines are available for reboosting the spacecraft and making
major orbital changes.
Construction of the Zarya module began at KhSC in December 1994.
It was shipped to the Baikonur Cosmodrome, Kazakstan, launch site
to begin launch preparations in January 1998. The three-stage
proton rocket will launch the module into a 137 by 211 statute
mile orbit. For launch, the module's systems will be in an idle
mode to conserve battery power. After reaching the initial
elliptical orbit and separating from the Proton's third stage, a
set of preprogrammed commands will automatically activate the
module's systems and deploy the solar arrays and communications
antennas. After several days of operational tests, the module
will be commanded to fire its engines and circularize its orbit
at an altitude of about 240 statute miles, the orbit at which
Endeavour will later rendezvous and capture the spacecraft to
attach it to the U.S.-built Unity connecting module.
