   Title: Space Robotics & Autonomous Systems Development

Description:

In the coming decades, autonomous systems (robotics, spacecraft, aircraft, etc.) will continue to change the way space is explored in even more fundamental ways, impacting both human and science exploration. Current research has been looking at developing autonomous spacecraft and UAVs which have, in effect, a ‘brain’ and the ability to follow commands given in system English rather than computer code. By being able to think for themselves, the satellites can then react to the environment around them, e.g. avoiding asteroids; and the technology may also, in time, reduce the need for humans to go into space for mere routine tasks. While development of autonomous UAV will give rise to a new age of   traffic monitoring and surveillance, emergency services assistance, photogrammetry and surveying.  This research theme covers a wide range of topics which include both the development of traditional AI technologies, core functionalities and their pragmatic integration with other technologies in a prototype experimental UAV system. In addition to this, it covers the kinematics, dynamics, control and verification of space robotic systems for manned and unmanned on-orbit servicing missions, theoretical modeling, simulation and experimental testing of autonomous systems using model spacecraft.

   Title: Launching Propulsion System Development

Description:

The Launch Propulsion Systems Technology Area (LPSTA) addresses technologies that enhance existing solid or liquid propulsion technologies or their related ancillary systems or significantly advance the technology readiness level (TRL) of newer systems like air-breathing, unconventional, and other launch technologies. Launch vehicle, in spaceflight, is a rocket-powered vehicle used to transport a spacecraft beyond Earth’s atmosphere, either into orbit around Earth or to some other destination in outer space. Launching systems include the launching vehicle, launching pad and the infrastructure. This thematic area is mainly focused on the overall system design, analysis and development of different launching systems and sub systems, design of efficient propulsion systems, selection of proper types of the propellants, develop new types of propellants, the physical and chemical properties of the propellants used for aerospace system and system miniaturization.
