The Space Sciences Laboratory (SSL) is an Organized Research Unit of the University of California, Berkeley.

It is located in the Berkeley Hills above the university campus. It has developed and continues to develop many projects in the space sciences.

SSL developed and maintains the SETI@home project which pioneered the application of distributed computing to the space sciences.
It created the related projects Stardust@home and BOINC.
It is home to the Space Physics Research Group, which does Plasma physics research.
It has developed many satellite missions and serves as a ground station for those missions. Some of the satellites it has developed are:

• The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) satellite
• The Time History of Events and Macroscale Interactions during Substorms (THEMIS) satellite constellation
• The Fast Auroral Snapshot Explorer (FAST)
• The Cosmic Hot Interstellar Plasma Spectrometer (CHIPSat)
• The Extreme Ultraviolet Explorer (EUVE)
• The Infrared Spatial Interferometer (ISI)

SSL does science education outreach via the Center for Science Education (CSE).

The CST-100 (Crew Space Transportation) crew capsule is a spacecraft design proposed by Boeing in collaboration with Bigelow Aerospace as their entry for NASA's Commercial Crew Development (CCDev) program.

Its primary mission would be to transport crew to the International Space Station, and to private space stations such as the proposed Bigelow Aerospace Commercial Space Station.

SC Modeler is a software for the conceptual design, visualization and analysis of satellite constellations.

It was written for aerospace engineers and other professionals involved in development of space-based communications systems, Earth observation systems, navigation systems.

SC Modeler provides an integrated modeling environment and all the necessary functionality for visualizing a satellite constellation and carrying out many tasks of constellation analysis including visibility studies and analysis of the geometry of communication links. The software includes a set of productivity tools which offers an efficient and convenient way of managing model properties, constellation parameters and design constraints.

AVM Dynamics is a software and consultancy company based in Miami, Florida, USA. 

The company proposes a softwar to help the conceptual design, analysis and visualization of a satellite constellation: SC Modeler software.

Grasshopper is an experimental technology-demonstrator, suborbital reusable launch vehicle (RLV), a vertical takeoff, vertical landing (VTVL) rocket announced in 2011 for low-altitude testing that began in 2012. 

Grasshopper is being developed and tested by Space Exploration Technologies (SpaceX) in order to assist development of the reusable Falcon 9 and reusable Falcon Heavy rockets, which will require vertical landings of the near-empty Falcon 9 and Falcon Heavy first-stage tanks and engine assemblies.

Grasshopper is one element of the multi-element SpaceX reusable rocket launching system test program, a program that includes both low-altitude, low-speed testing of the Grasshopper vehicle at SpaceX' Texas test site, as well as high-altitude, high-speed controlled-descent tests of post-mission (spent) Falcon 9 booster stages on Falcon 9 commercial missions beginning in mid-2013.

CSTS (Crew Space Transportation System) or ACTS (Advanced Crew Transportation System) was a human spaceflight system proposal.

It was originally a joint project between the European Space Agency (ESA) and the Russian Space Agency (FKA), but is now solely an ESA project. It aims to design a spacecraft for low earth orbit operations such as servicing the International Space Station but also capable of exploration of the Moon and beyond. This study was conceived as a basic strategic plan to keep a viable European human space program alive when NASA officials announced the NASA's Vision for Space Exploration Orion spacecraft.

CSTS had completed an initial study phase, which lasted for 18 months from September 2006 to spring 2008, before the project was shut down before an ESA member state conference in November 2008. 

O/OREOS (Organism/Organic Exposure to Orbital Stresses) is a nanosatellite of 5.5 kilogram, launched on November 19, 2010.

It is an automated laboratory that contains two separate experiments on board. It has been developed by the Small Spacecraft Division at NASA Ames Research Center, and successfully launched as a secondary payload on a Minotaur IV rocket from Kodiak Island, Alaska on November 19, 2010.

The O/OREOS satellite is NASA's first cubesat to demonstrate the capability to have two distinct, completely independent science experiments on an autonomous satellite. One experiment will test how microorganisms survive and adapt to the stresses of space; the other will monitor the stability of organic molecules in space.

Synoptic Optical Long-term Investigations of the Sun (SOLIS) is a new synoptic facility for solar observations over a long time frame that is funded by the National Science Foundation (NSF) and designed and built by the National Solar Observatory (NSO).

SOLIS will provide unique observations of the Sun on a continuing basis for several decades to understand the solar activity cycle, sudden energy releases in the solar atmosphere, and solar irradiance changes and their relationship to global change. 

SOLIS is composed of a single equatorial mount (right) carrying three telescopes. The first system is located on top of the Kitt Peak Vacuum Telescope building (left), and the NSO Long Range Plan calls for a global network of two more VSMs to enable continuous solar observations.

APCO Technologies is specialised in the design and manufacture of high quality mechanical and electromechanical equipment for the space, and nuclear industries. APCO Technologies is mainly project oriented and provides  solutions to customer's specific requirements.

APCO Technologies performs feasibility studies, thermal and mechanical analysis, detailed design, hardware development, as well as the manufacturing, integration and testing of the equipment it develops.

The Astronautical Society of India (ASI) was set up in 1990 to foster the development of astronautics in India.

ASI is engaged in the dissemination of technical and other information related to astronautics by conducting technical meetings, bringing out technical publications and organising exhibitions. The society is also playing an active role to promote the interests of other developing countries in the field of astronautics.
