Orbital Vehicle is the temporary name of an Indian manned spacecraft in development. The capsule will be designed to carry three people, and a planned upgraded version will be equipped with a rendezvous and docking capability. In its maiden manned mission, ISRO's largely autonomous 3-ton capsule will orbit the Earth at 248 miles (400 km) in altitude for up to seven days with a two-person crew on board. The crew vehicle would launch atop of ISRO's GSLV Mk II, currently under development. It will be equipped with emergency mission abort and emergency escape that can be done at the first stage and second stage of the rocket. In spring 2009 the full-scale mock-up of crew capsule of OV was built and delivered to Satish Dhawan Space Centre for training of Indian astronauts. The OV is scheduled to be launched with astronauts into space around 2015.
O'Neill began researching high-energy particle physics at Princeton in 1954 after he received his doctorate from Cornell University. Two years later, he published his theory for a particle storage ring. This invention allowed particle physics experiments at much higher energies than had previously been possible. In 1965 at Stanford University, he performed the first colliding beam physics experiment.
While teaching physics at Princeton, O'Neill became interested in the possibility that humans could live in outer space. He researched and proposed a futuristic idea for human settlement in space, the O'Neill cylinder, in "The Colonization of Space", his first paper on the subject. He held a conference on space manufacturing at Princeton in 1975. Many who became post-Apollo-era space activists attended. O'Neill built his first mass driver prototype with professor Henry Kolm in 1976. He considered mass drivers critical for extracting the mineral resources of the Moon and asteroids. His award-winning book The High Frontier: Human Colonies in Space inspired a generation of space exploration advocates. He died of leukemia in 1992.
