This Boeing photograph shows the Node 1, Unity module, Flight Article (at right) and the U.S. Laboratory module, Destiny, Flight Article for the International Space Station (ISS) being manufactured in the High Bay Clean Room of the Space Station Manufacturing Facility at the Marshall Space Flight Center. The Node 1, or Unity, serves as a cornecting passageway to Space Station modules. The U.S. built Unity module was launched aboard the orbiter Endeavour (STS-88 mission) on December 4, 1998 and connected to the Zarya, the Russian-built Functional Energy Block (FGB). The U.S. Laboratory (Destiny) module is the centerpiece of the ISS, where science experiments will be performed in the near-zero gravity of space. The U.S. Laboratory/Destiny was launched aboard the orbiter Atlantis (STS-98 mission) on February 7, 2001. The ISS is a multidisciplinary laboratory, technology test bed, and observatory that will provide unprecedented undertakings in scientific, technological, and international experimentation.

The U.S. Laboratory (Destiny) module is the centerpiece of the ISS, where science experiments will be performed in the near-zero gravity in space. The Destiny Module was launched aboard the Space Shuttle Orbiter Atlantis (STS-98 mission) on February 7, 2001. The aluminum module is 8.5 meters (28 feet) long and 4.3 meters (14 feet) in diameter. The laboratory consists of three cylindrical sections and two endcones with hatches that will be mated to other station components. A 50.9-centimeter- (20-inch-) diameter window is located on one side of the center module segment. This pressurized module is designed to accommodate pressurized payloads. It has a capacity of 24 rack locations, and payload racks will occupy 13 locations especially designed to support experiments.

This photograph, taken by the Boeing Company,shows Boeing technicians preparing to install one of six hatches or doors to the Node 1 (also called Unity), the first U.S. Module for the International Space Station (ISS). The Node 1, or Unity, serves as a cornecting passageway to Space Station modules and was manufactured by the Boeing Company at the Marshall Space Flight Center from 1994 to 1997. The U.S. built Unity module was launched aboard the orbiter Endeavour (STS-88 mission) on December 4, 1998 and connected to the Zarya, the Russian-built Functional Energy Block (FGB).

From to left to right, bottom, are astronauts Daniel T. Barry, Julie Payette and Ellen Ochoa. On top are cosmonaut Valery I. Tokarev, along with astronauts Tamara E. Jernigan and Kent V. Rominger. Astronaut Rick D. Husband is between Rominger and Ochoa. Payette represents the Canadian Space Agency (CSA) and Tokarev is with the Russian Space Agency (RSA).

STS105-E-5109 (12 August 2001) --- Scott J. Horowitz (left), STS-105 commander, and cosmonaut Vladimir N. Dezhurov, Expedition Three flight engineer, move into Unity Node 1 during the initial ingress into the International Space Station (ISS) during the STS-105 mission. Dezhurov, accompanied by cosmonaut Mikhail Tyurin and astronaut Frank L. Culbertson, Jr., will be replacing astronauts Susan J. Helms and James S. Voss and cosmonaut Yury V. Usachev as the temporary residents of the ISS. This image was taken with a digital still camera.

STS088-332-010 (4-15 Dec. 1998) --- Cosmonaut Sergei K. Krikalev (left), mission specialist representing the Russian Space Agency (RSA), and astronaut Robert D. Cabana mission commander, plan their approach to tasks as they huddle at an internal hatch in the Russian built FGB, also called Zarya. All six STS-88 crew members were involved in tasks to ready Zarya and the now-connected U.S. Node 1, also called Unity, for their International Space Station (ISS) roles. Krikalev has been named as a member of the first ISS crew.

STS088-332-017 (4-15 Dec. 1998) --- From the left, astronauts Nancy J. Currie, mission specialist; Robert D. Cabana, commander, and Jerry L. Ross, mission specialist, go about various chores designed to put the United States-built Unity Connecting Module (Node 1) in readiness for its impending release in Earth-orbit. Currie talks with ground controllers while Cabana logs a note and Ross checks a supply bag. After devoting the major portion of its mission time to various tasks to ready the Russian-built FGB Module (Zarya) and the docked United States-built node, the six-member crew released the tandem from the Space Shuttle Endeavour’s cargo bay toward mission’s end.

iss073e0814466 (Sept. 18, 2025) --- NASA astronauts Zena Cardman and Jonny Kim, both Expedition 73 flight engineers, pose for a fun portrait inside the International Space Station’s Unity module shortly after the arrival of Northrop Grumman’s Cygnus XL cargo craft. The duo had just begun unpacking several tons of new science experiments, supplies, and hardware.

STS105-E-5175 (13 August 2001) --- Astronaut James S. Voss, retrieves a small tool from a tool case in the U.S.-built Unity node aboard the International Space Station (ISS). The Expedition Two flight engineer is only days away from returning to Earth following five months aboard the orbital outpost. The image was recorded with a digital still camera.

S96-E-5078 (31 May 1999) --- Flight Day 5 activity called for some of Discovery's crew members to work in the Unity node, part of the International Space Station (ISS). From the left are astronauts Tamara Jernigan and Julie Payette, along with cosmonaut Valery I. Tokarev. Payette represents the Canadian Space Agency (CSA) and Tokarev is with the Russian Space Agency (RSA). The photo was taken at 01:50:38, May 31, 1999.

ISS011-E-05163 (17 April 2005) --- Astronaut John L. Phillips, Expedition 11 NASA ISS science officer and flight engineer, poses for a photo with the ISS wet/dry vacuum cleaner assembly he used to catch floating debris from the top of a food can in the Unity node of the International Space Station (ISS).

In the Space Station Processing Facility, an overhead crane moves the Unity connecting module to the payload canister for transfer to the launch pad. Part of the International Space Station (ISS), Unity is scheduled for launch aboard Space Shuttle Endeavour on Mission STS-88 in December. The Unity is a connecting passageway to the living and working areas of ISS. While on orbit, the flight crew will deploy Unity from the payload bay and attach Unity to the Russian-built Zarya control module which will be in orbit at that time

In the Space Station Processing Facility, a worker places the nameplate on the side of the Unity connecting module, part of the International Space Station. Unity was expected to be transported to Launch Pad 39A on Oct. 26 for launch aboard Space Shuttle Endeavour on Mission STS-88 in December. The Unity is a connecting passageway to the living and working areas of ISS. While on orbit, the flight crew will deploy Unity from the payload bay and attach Unity to the Russian-built Zarya control module which will be in orbit at that time

In the Space Station Processing Facility, Joan Higgenbotham, with KSC's Astronaut Office Computer Support, checks placement of the nameplate for the Unity connecting module, part of the International Space Station.
