Robotic Servicing Of Geosynchronous Satellites Program
DARPA's Robotic Servicing of Geosynchronous Satellites (RSGS) program leverages commercial space technology to inspect and repair aging or broken satellites in the geosynchronous Earth orbit (GEO), about 35,786 kilometers (22,236 miles) from Earth. Background According to DARPA, no options exist for visual diagnosis, upgrades, or repairs of a malfunctioning satellite's components, thus rendering these satellites space junk. In 2020, DARPA selected Northrop Grumman's subsidiary SpaceLogistics as its RSGS partner. The U.S. Naval Research Laboratory designed and developed the RSGS robotic arm with DARPA funding. The robotic arm has completed key tests and is on track to be launched to GEO in 2024 by Northrop Grumman's 3000-kilogram spacecraft. After launch in 2024, there will be a period for checkout and calibration activities. The DARPA robotic mechanic is anticipated to start making on-orbit service calls in space in 2025.

DARPA
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet Union, Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource The name of the organization first changed from its founding name, ARPA, to DARPA, in March 1972, changing back to ARPA in February 1993, then reverted to DARPA in March 1996. ''The Economist'' has called DARPA "the agency that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OSAM-1
OSAM-1 (On-orbit Servicing, Assembly, and Manufacturing 1) was a 2016-2024 conceptual NASA mission and spacecraft designed to test on-orbit refueling of satellites. The program was cancelled in 2024, two years ahead of its planned launch date. It was initially known as Restore-L. Originally scheduled to launch in 2020, its launch at the time of cancellation was planned for no earlier than 2026. The primary objective of the concept mission and spacecraft was the complex refueling of Landsat 7, a satellite launched in 1999, that was not designed for on-orbit servicing. This would have involved grasping the satellite with a mechanical arm, gaining access to the satellite's fuel tank by cutting through insulation and wires and unscrewing a bolt, and then attaching a hose to pump in hydrazine fuel. At the time the mission was conceived, it was expected to be the first refueling of a satellite in space, and a demonstration of the potential to repair some of the thousands of active sat ...

Robotic Satellite Repair Vehicles
Robotics is the interdisciplinary study and practice of the design, construction, operation, and use of robots. Within mechanical engineering, robotics is the design and construction of the physical structures of robots, while in computer science, robotics focuses on robotic automation algorithms. Other disciplines contributing to robotics include electrical engineering, electrical, control engineering, control, software engineering, software, Information engineering (field), information, electronics, electronic, telecommunications engineering, telecommunication, computer engineering, computer, mechatronic, and materials engineering, materials engineering. The goal of most robotics is to design machines that can help and assist humans. Many robots are built to do jobs that are hazardous to people, such as finding survivors in unstable ruins, and exploring space, mines and shipwrecks. Others replace people in jobs that are boring, repetitive, or unpleasant, such as cleaning, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
