Deep Space Industries (DSI) is an American company created with the objective to mine asteroids for metals and other materials.

DSI believes the human race is ready to begin harvesting the resources of space.  DSI Mission is the following: to build on the heritage of the first age of space exploration and harness the power of a new age of information to locate, explore, harvest and utilize the vast numbers of asteroids in Earth's community.  Deep Space Industries is playing the long game and will position itself to be the leader in space resource harvesting and utilization by developing a carefully planned track record of capability, credibility and expertise.

Skylon is a design for a spaceplane by the British company Reaction Engines Limited (REL).

It uses SABRE, a combined-cycle, air-breathing rocket engine, to reach orbit in a single stage. A fleet of vehicles is envisaged; the design is aiming for re-usability for more than 200 times.

As of 2012, only a small portion of the funding required to develop and build Skylon had been secured. The research and development work on the SABRE engine design is proceeding under a small European Space Agency (ESA) grant. 

AVATAR (from "Aerobic Vehicle for Hypersonic Aerospace TrAnspoRtation") was a concept development effort for a single-stage reusable spaceplane capable of horizontal takeoff and landing, by India's Defense Research and Development Organization along with Indian Space Research Organization and other research institutions.

The mission concept was for cheaper military and civilian satellite space launches. The idea was to develop a hyperplane vehicle that can take off from conventional airfields, collect air in the atmosphere on the way up, liquefy it, separate oxygen and store it on board for subsequent flight beyond the atmosphere. The AVATAR RLV was first announced in May 1998 at the Aero India 98 exhibition held at Bangalore. It was planned to be the size of a MiG-25 fighter and would be capable of delivering a 500 kg to 1,000 kg payload to low earth orbit at very low cost for an estimated vehicle life of 100 launches.

ASTOS is a Trajectory optimization and simulation tool for launch and re-entry missions, orbit transfers, design optimization and for re-entry safety assessments.

It solves Aerospace problems with a data driven interface and automatic initial guesses. Since 1989, the European Space Agency has developed, and improved this trajectory optimization environment to compute optimal trajectories for a variety of complex multi-phase Optimal control problems. ASTOS is being extensively used at ESA and aerospace industry community to calculate optimal launch and entry trajectories and was one of the tools used by ESA to assess the risk due to the ATV 'Jules Verne' re-entry. ASTOS is compatible with Windows, Linux and Mac OS platforms.

It is maintained and commercialized by ASTOS Solutions Gmbh for the European Space Agency.
