ArchAtlas is a web-orientated archaeological mapping and research project. It is developed at the Department of Archaeology, University of Sheffield, UK.

The ArchAtlas project aims to provide a visual summary of spatial processes in prehistoric and early historic times, such as the spread of farming, the formation of trade contacts, and the growth of urban systems, and to illustrate the locations of key archaeological sites. It uses GIS techniques to integrate georeferenced information on archaeological sites, cultural entities and contact routes with environmental data and satellite imagery.

The Society for Popular Astronomy is a national astronomical society based in the United Kingdom for beginners to amateur astronomy.

It was founded in 1953 as the Junior Astronomical Society.

The European Association of Remote Sensing Companies (EARSC) is a non-profit-making organisation which is actively involved in coordinating and strengthening the Earth-observation (EO) chain and promoting the European geo-information industry.

EARSC is open to corporative and observer members with deeply interest in providing services delivering information based on observations of the Earth and its environment.

Since 1989, EARSC has provided its Members technical expertise and policy guidance. The Association maintains close links with key European Institutions, including Industry, ESA and National Space Agencies, providing a key unified voice on wider European issues.

Esri  is a worldwide supplier of Geographic Information System (GIS) software and geodatabase management applications.

Esri is headquartered inRedlands, California, USA.

Pratt & Whitney Rocketdyne (PWR) was a United States company that designed and produced rocket engines that use liquid propellants.

PWR was a division of Pratt & Whitney. It was a provider of high-value propulsion, power, energy and innovative system solutions used in a wide variety of government and commercial applications, including the main engines for the space shuttle, Atlas and Delta launch vehicles, missile defense systems and advanced hypersonic engines.

Pratt & Whitney Rocketdyne was headquartered in Canoga Park, Calif., USA.

STEREO (Solar TErrestrial RElations Observatory) is a NASA solar observation mission.

Two nearly identical spacecraft were launched into orbits around the sun that cause them to respectively pull farther ahead of and fall gradually behind the Earth. This will enable stereoscopic imaging of the Sun and solar phenomena, such as coronal mass ejections.

LMSAL is a department of the Lockheed Martin Advanced Technology Center (ATC) in Palo Alto, CA, USA.

LMSAL gathers a group of scientists and engineers who design, build, and operate solar and astrophysical observing instruments. LMSAL and the Space Physics Lab comprise the ATC's Space Sciences Office.

The Interface Region Imaging Spectrograph (or IRIS) is a space probe, planned by NASA, to observe the Sun.

It is a NASA Small Explorer program mission to investigate the physical conditions of the solar limb, particularly the chromosphere of the Sun.

IRIS will observe how solar material moves, gathers energy, and heats up as it travels through a little-understood region in the sun's lower atmosphere. Tracking how material and energy move through this region is a crucial part of understanding the dynamics of the sun.

NASA announced on June 19, 2009 that IRIS was selected from six small explorer mission candidates^.

Nautilus-X is a multi-mission space exploration vehicle imagined by the Technology Applications Assessment Team of NASA.

The spacecraft was designed for long duration (one to twenty-four months) exo-atmospheric space journeys for a six-person crew. In order to limit the effects of microgravity on human health, the spacecraft would be equipped with a centrifuge.

Nautilus-X stands for Non-Atmospheric Universal Transport Intended for Lengthy United States Exploration.

The Space Launch System, or SLS, is a Space Shuttle-derived heavy launch vehicle being designed by NASA.

It follows the cancellation of the Constellation Program, and is to replace the retired Space Shuttle.
