Alaska Aerospace Corporation (AAC)'s core business is space launch. It developed, owns, and operates the Kodiak Launch Complex, a spaceport on Kodiak Island, Alaska, that provides access to space for commercial and government interests. 

ARCA Space is a non profit organization with main objective being the exploration and colonization of space.

In order to reach these objectives, ARCA builds and launches cost effective space vehicles. ARCA Space is using technologies already existing, in an innovative ways.

The Kodiak Launch Complex (KLC) is a commercial rocket launch facility for sub-orbital and orbital space launch vehicles.

It is owned and operated by the Alaska Aerospace Corporation, a public corporation of the State of Alaska. The facility is located on Kodiak Island, Alaska.

The Kodiak spaceport has two launch pads with a mission control center with high-speed communications and data links. There is a clean room for preparing satellites for launch, a fully enclosed 17-story-tall rocket assembly building and two independent range and telemetry systems. 

Air Liquide S.A. is a French multinational company which supplies industrial gases and services to various industries ; this includes cryogenic propellants and cryogenic stages for launch vehicles.

Founded in 1902, it is currently (Nov. 2012) one of the world's largest suppliers of industrial gases by revenues, and has operations in over 80 countries. It is headquartered in Paris, France. It also has a major site in Japan, as well as in Houston, TX, and Newark, DE, USA.

Operator of the Apstar series of communications satellites in the Asia Pacific region, providing satellite services, including broadband media and television services.

APT launched its first satellite, APSTAR-1, in 1994.

APSTAR-V and APSTAR-VI is the new generation (as of Nov. 2012) of high-power and high-reliability communication satellites.

A Tracking and Data Relay Satellite (TDRS) is a type of communications satellite.

Such a satellite forms part of the Tracking and Data Relay Satellite System (TDRSS) used by NASA and other United States government agencies for communications to and from independent "User Platforms" such as satellites, balloons, aircraft, and the International Space Station. This system was designed to replace a pre-existing worldwide network of ground stations that had supported all of NASA's manned flight missions and unmanned satellites in low-Earth orbits. The primary system design goal was to increase the amount of time that these spacecraft were in communication with the ground and improve the amount of data that could be transferred. These TDRSS satellites are all designed and built to be launched to and function in geosynchronous orbit.

The NASA Visualization Explorer — a nice way to get stories about NASA's exploration of the Earth, sun, moon, planets and universe. Each story will take you on a remarkable journey into the science of NASA, brought to life.

NASA's Science Mission Directorate is organized into four disciplines: Heliophysics, Planetary, Astrophysics and Earth science. This project is putting imagery and data from this exploration at your fingertips.
