The European Satellite Operators' Association (ESOA) was formed in March 2002 to represent the interests of the industry with key European organisations, including the European Commission, Parliament, Council and the European Space Agency as well as other international organisations.

ESOA's goals include ensuring that satellites benefit from the appropriate political, industrial and regulatory environment to fulfil their vital role in the delivery of communications. ESOA is governed by a Board of Directors, made up of the CEO's of its Member Companies.

ESOA is a CEO-driven association representing 22 global and regional satellite operators. ESOA provides thought-leadership and is recognised as the representative body for satellite operators by international, regional and national bodies including regulators, policymakers, standards-setting organisations such as 3GPP and international organisations such as the International Telecommunications Union and the World Economic Forum.

The Iranian Space Agency (ISA) is Iran's governmental space agency.

Iran is an active participant in the Asian space race and became an orbital-launch-capable nation in 2009. 

The American Geophysical Union (AGU) is a nonprofit organization of geophysicists with the mission to promote discovery in Earth and space science for the benefit of humanity.

It is consisting of thousands of members from 144 countries, the members being individual scientists.

AGU's activities are focused on the organization and dissemination of scientific information in the interdisciplinary and international field of geophysics. The geophysical sciences involve four fundamental areas: atmospheric and ocean sciences; solid-Earth sciences; hydrologic sciences; and space sciences.

Philae is a robotic European Space Agency lander that accompanies its Rosetta spacecraft. It is designed to land on Comet 67P/Churyumov-Gerasimenko shortly after arrival in 2014. The lander is named after Philae island in the Nile, where an obelisk was found that was used along with the Rosetta Stone to decipher Egyptian hieroglyphic.

Just as the Philae(*) Obelisk and the Rosetta Stone provided the keys to an ancient civilisation, the Philae lander and the Rosetta orbiter aim to unlock the mysteries of the oldest building blocks of our Solar System - comets.

(*) Philae is the island in the river Nile on which an obelisk was found that had a bilingual inscription including the names of Cleopatra and Ptolemy in Egyptian hieroglyphs. This provided the French historian Jean-François Champollion with the final clues that enabled him to decipher the hieroglyphs of the Rosetta Stone and unlock the secrets of the civilisation of ancient Egypt.

The Deep Space Atomic Clock project (DSAC), will fly and validate a miniaturized, ultra-precise mercury-ion atomic clock that is orders of magnitude more stable than today's best navigation clocks.

DSAC: Key Mission Facts

• The Deep Space Atomic Clock will be orders of magnitude more stable than any other atomic clock flown in space, as well as smaller and lighter.
• This NASA Technology Demonstration Mission will shift paradigms for navigating spacecraft to distant destinations, enabling collection of more data with better precision; and enabling autonomous radio navigation for time-critical events such as orbit insertion or landing.
• This mission will deliver the next generation of deep-space radio science.

Precise radio navigation -- using radio frequencies to determine position -- is vital to the success of a range of deep-space exploration missions. Ground-based atomic clocks have long been the cornerstone of most deep-space vehicle navigation because they provide root data necessary for precise positioning. The Deep Space Atomic Clock will deliver the same stability and accuracy for spacecraft exploring the solar system. This new capability could forever change the way we conduct deep-space navigation -- by eliminating the need to "turn signals around" for tracking. Much the same way modern Global Positioning Systems, or GPS, use one-way signals to enable terrestrial navigation services, the Deep Space Atomic Clock will provide the same capability in deep-space navigation -- with such extreme accuracy that researchers will be required to carefully account for the effects of relativity, or the relative motion of an observer and observed objected, as impacted by gravity, space and time (clocks in GPS-based satellite, for example, must be corrected to account for this effect, or their navigational fixes begin to drift).

Over the past 20 years, engineers at NASA's Jet Propulsion Laboratory in Pasadena, Calif., have been steadily improving and miniaturizing the mercury-ion trap atomic clock, preparing it to operate in the harsh environment of deep space. In the laboratory setting, the Deep Space Atomic Clock's precision has been refined to permit drift of no more than 1 nanosecond in 10 days.

Now (Dec. 2013) the DSAC team is preparing a miniaturized, low-mass atomic clock -- orders of magnitude more accurate and stable than any other atomic clock flown in space, while still being smaller and lighter -- for a test flight in low-Earth orbit. The clock will make use of GPS signals to demonstrate precision orbit determination and confirm its performance, promising new savings on mission operations costs, delivering more science data and enabling further development of deep-space autonomous radio navigation.
The DSAC project currently is building a demonstration unit and payload to be hosted on a spacecraft provided by Surrey Satellite Technologies U.S. of Englewood, Colo. It will launch to Earth orbit in 2015, where the payload will be operated for at least a year to demonstrate its functionality and utility for one-way-based navigation.

Juno is a NASA New Frontiers mission to the planet Jupiter.

Juno was launched from Cape Canaveral Air Force Station on August 5, 2011 and will arrive in July 2016.

The spacecraft is to be placed in a polar orbit to study Jupiter's composition, gravity field, magnetic field, and polar magnetosphere. Juno will also search for clues about how it formed, including whether Jupiter has a rocky core, the amount of water present within the deep atmosphere, and how its mass is distributed. It will also study its deep winds, which can reach speeds of 618 kilometers per hour (384 mph).

The GSI Helmholtz Centre for Heavy Ion Research (German: GSI Helmholtzzentrum für Schwerionenforschung GmbH) is a federally and state co-funded heavy ion research center in the Wixhausen suburb of Darmstadt, Germany. GSI was founded in 1969 as the Society for Heavy Ion Research (German: Gesellschaft für Schwerionenforschung), abbreviated GSI, to conduct research on and with heavy-ion accelerators. 

The laboratory performs basic and applied research in physics and related natural science disciplines. Main fields of study include plasma physics, atomic physics, nuclear structure and reactions research, biophysics and medical research. The lab is a member of the Helmholtz Association of German Research Centres.

GSI operates a worldwide unique large-scale accelerator facility for heavy ions and currently employs about 1.100 people. In addition approximately 1.000 researchers from universities and other research institutes around the world use the facility for their experiments.

GSI is a limited liability company (Ger. GmbH). Associates are the German Federal Government (90 per cent), the State of Hessen (8 per cent), the State of Rhineland-Palatinate (1 per cent) and the Free State of Thuringia (1 per cent). They are represented in the board of directors by the Federal Ministry of Education and Research and the respective Ministries. GSI is a member of the Helmholtz Association, Germany's largest research organisation.

The goal of the scientific research conducted at GSI Helmholtzzentrum für Schwerionenforschung is to reach a better understanding of the structure and behavior of the world that surrounds us.

The Space Surveillance Telescope program (SST) is DARPA's ground based, advanced, optical system for detection and tracking of faint objects in space such as asteroids. It is also to be employed for space defense missions. The program is designed to advance, or expand, space situational awareness, and be able to quickly provide wide area search capability.

The large curved focal surface array sensors are considered to be an innovative design. It encompasses improvements in detection sensitivity, has short focal length, wide field of view, and improvements in step-and-settle abilities.  SST detects, tracks, and can discern small, obscure objects, in deep space with a "wide field of view system". It is a single telescope with the dual abilities. First the telescope is sensitive enough to allow for detection, also, of small, dimly lit objects (low reflectivity). Second it is capable of quickly searching the visible sky. This combination is a difficult achievement in a single telescope design.
