Russian technicians work on the module shortly after it completed a pressurization test. In the foreground is the forward portion of the module, including the spherical transfer compartment and its three docking ports. The forward port docked with the cornected Functional Cargo Block, followed by Node 1. Launched via a three-stage Proton rocket on July 12, 2000, the Zvezda Service Module serves as the cornerstone for early human habitation of the Station, providing living quarters, life support system, electrical power distribution, data processing system, flight control system, and propulsion system. It also provides a communications system that includes remote command capabilities from ground flight controllers. The 42,000-pound module measures 43 feet in length and has a wing span of 98 feet. Similar in layout to the core module of Russia's Mir space station, it contains 3 pressurized compartments and 13 windows that allow ultimate viewing of Earth and space.

Skylab's success proved that scientific experimentation in a low gravity environment was essential to scientific progress. A more permanent structure was needed to provide this space laboratory. President Ronald Reagan, on January 25, 1984, during his State of the Union address, claimed that the United States should exploit the new frontier of space, and directed NASA to build a permanent marned space station within a decade. The idea was that the space station would not only be used as a laboratory for the advancement of science and medicine, but would also provide a staging area for building a lunar base and manned expeditions to Mars and elsewhere in the solar system. President Reagan invited the international community to join with the United States in this endeavour. NASA and several countries moved forward with this concept. By December 1985, the first phase of the space station was well underway with the design concept for the crew compartments and laboratories. Pictured are two NASA astronauts, at Marshall Space Flight Center's (MSFC) Neutral Buoyancy Simulator (NBS), practicing construction techniques they later used to construct the space station after it was deployed.

DELAMAR DRY LAKE BED, Nev. -- The Boeing Company's CST-100 boilerplate crew capsule floats toward a smooth landing beneath three main parachutes after being released from an Erickson Sky Crane helicopter at about 11,000 feet above Delamar Dry Lake Bed near Alamo, Nev. This is one of two tests that Boeing will perform for NASA's Commercial Crew Program CCP in order to validate the spacecraft's parachute system architecture and deployment scheme, characterize pyrotechnic shock loads, confirm parachute sizing and design, and identify potential forward compartment packaging and deployment issues. In 2011, NASA selected Boeing during Commercial Crew Development Round 2 CCDev2) activities to mature the design and development of a crew transportation system with the overall goal of accelerating a United States-led capability to the International Space Station. The goal of CCP is to drive down the cost of space travel as well as open up space to more people than ever before by balancing industry’s own innovative capabilities with NASA's 50 years of human spaceflight experience. Six other aerospace companies also are maturing launch vehicle and spacecraft designs under CCDev2, including Alliant Techsystems Inc. ATK, Excalibur Almaz Inc., Blue Origin, Sierra Nevada, Space Exploration Technologies SpaceX, and United Launch Alliance ULA. For more information, visit www.nasa.gov/commercialcrew.

KENNEDY SPACE CENTER, FLA. -- Lowered on a movable work platform or bucket inside the payload bay of orbiter Endeavour, STS-88 Mission Specialists Jerry L. Ross (far right) and James H. Newman (second from right) get a close look at the Orbiter Docking System. At left is the bucket operator and Wayne Wedlake, with United Space Alliance at Johnson Space Center. The STS-88 crew members are in Orbiter Processing Facility Bay 1 to participate in a Crew Equipment Interface Test (CEIT) to familiarize themselves with the orbiter's midbody and crew compartments. Targeted for liftoff on Dec. 3, 1998, STS-88 will be the first Space Shuttle launch for assembly of the International Space Station (ISS). The primary payload is the Unity connecting module which will be mated to the Russian-built Zarya control module, expected to be already on orbit after a November launch from Russia. While on orbit during STS-88, Unity will be latched atop the Orbiter Docking System in the forward section of Endeavour's payload bay for the mating of the two modules. After the mating, Ross and Newman are scheduled to perform three spacewalks to connect power, data and utility lines and install exterior equipment. The first major U.S.-built component of ISS, Unity will serve as a connecting passageway to living and working areas of the space station. Unity has two attached pressurized mating adapters (PMAs) and one stowage rack installed inside. PMA-1 provides the permanent connection point between Unity and Zarya; PMA-2 will serve as a Space Shuttle docking port. Zarya is a self-supporting active vehicle, providing propulsive control capability and power during the early assembly stages. It also has fuel storage capability

CAPE CANAVERAL, Fla. – In NASA Kennedy Space Center's Firing Room 4, NASA management watch the console during the countdown toward launch of space shuttle Discovery on the STS-128 mission. Seated (starting second from left) are Robert Lightfoot, director of NASA's Marshall Space Flight Center; Bob Cabana, director of Kennedy Space Center; Janet Kavandi, deputy director of Flight Crew Operations at Johnson Space Center; John Shannon, Shuttle Program manager (leaning forward); Bill Gerstenmaier, associate administrator for Space Operations; and Chris Scolese, NASA associate administrator. Standing in front of the windows at right is Charles Bolden, NASA Administrator. Liftoff from Launch Pad 39A was on time at 11:59 p.m. EDT. The first launch attempt on Aug. 24 was postponed due to unfavorable weather conditions. The second attempt on Aug. 25 also was postponed due to an issue with a valve in space shuttle Discovery's main propulsion system. The STS-128 mission is the 30th International Space Station assembly flight and the 128th space shuttle flight. The 13-day mission will deliver more than 7 tons of supplies, science racks and equipment, as well as additional environmental hardware to sustain six crew members on the International Space Station. The equipment includes a freezer to store research samples, a new sleeping compartment and the COLBERT treadmill. Photo credit: NASA/Kim Shiflett
