A control moment gyroscope (CMG) is an attitude control device generally used in spacecraft attitude control systems. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor's angular momentum. As the rotor tilts, the changing angular momentum causes a gyroscopic torque that rotates the spacecraft. CMGs differ from reaction wheels. The ISS employs a total of four CMGs as primary actuating devices during normal flight mode operation. The objective of the CMG flight control system is to hold the space station at a fixed attitude relative to the surface of the Earth.

The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. A GPS receiver calculates its position by precisely timing the signals sent by GPS satellites high above the Earth. Each satellite continually transmits messages that include the time the message was transmitted and, satellite position at time of message transmission. The receiver uses the messages it receives to determine the transit time of each message and computes the distance to each satellite using the speed of light. Each of these distances and satellites locations defines a sphere. The receiver is on the surface of each of these spheres when the distances and the satellites locations are correct. These distances and satellites locations are used to compute the location of the receiver using the navigation equations. This location is then displayed, perhaps with a moving map display or latitude and longitude; elevation or altitude information may be included.

The HTV is about 9.8 m long (including maneuvering thrusters at one end) and 4.4 m in diameter. Total mass is 10.5 tons, with a 6,000 kilograms (13,000 lb) payload. The baseline configuration uses one pressurized and one unpressurized segment and can carry 7,600 kg of cargo in total and is 9.2 m long. When two pressurized units are used together the cargo decreases slightly to about 7,000 kg, and the overall length is reduced to 7.4 m.
HTV-X is a robotic cargo spacecraft designed by JAXA to replace the HTV in delivering cargo to the ISS. It will load the unpressurized cargo on top of the spacecraft instead of inside like the HTV. The HTV-X has a length of 6.2 m, or 10 m with the unpressurised cargo module fitted. The payload fairing adaptor and payload dispenser have been widened from 1.7 m to 4.4 m to allow the pressurized cargo module to be swapped out for alternate modules, to add increased structural strength, and to accommodate the side hatch. The simplification of the overall structure will allow the launch mass of HTV-X to be dropped to 15,500 kg from HTV's 16,500 kg, while the maximum weight of cargo will be increased to 7,200 kg (net weight 5,850 kg excluding support structure weight) from HTV's 6,000 kg (net 4,000 kg).

Pressurized Mating Adapters: The International Space Station (ISS) uses three PMAs to interconnect spacecraft and modules with different docking mechanisms. The first two PMAs were launched with the Unity module in 1998 aboard STS-88. The third was launched in 2000 aboard STS-92. All the PMAs on the ISS are identical but used slightly differently, and all three perform the same basic function of connecting a common berthing mechanism (CBM) port of an ISS module to the Androgynous Peripheral Attach System (APAS) docking port of another module or visiting spacecraft. For this the PMAs carry a passive CBM port and a passive APAS port. They are pressurized and heated from the inside and through docking rings as well as external connections allow for power and data communications transfer.

The reusable Tethered Satellite System (TSS) was made up of a satellite attached to the Shuttle orbiter by a super strong cord which should be reeled into space from the Shuttle's cargo bay. The tether - which looked like a 12-mile-long (19.3 km) white bootlace - was scheduled to have electrically-conducting metal strands in its core. The conducting tether should generate electrical currents at a high voltage by the same basic principle as a standard electrical generator - by converting mechanical energy. The Tethered Satellite System had five major components: the deployer system, the tether, the satellite, the carriers on which the system was mounted and the science instruments.

The Wake Shield Facility is an experimental science platform. It was a 3.7 meter (12 ft) diameter, free-flying stainless steel disk. The WSF was deployed in the wake of the Space Shuttle at an orbital altitude of over 300 kilometers (186 mi), within the thermosphere, where the atmosphere is exceedingly tenuous. The forward edge of the WSF disk redirected atmospheric and other particles around the sides, leaving an ultra-vacuum in its wake. The resulting vacuum was used to study epitaxial film growth. These included gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs) depositions.
