This will increase the risk of the station being lost if an unlucky chain of bad events happens. The system could start tumbling if a crew was not on it to apply corrections and there was a failure with remote systems to allow for correction. By The Next Big Future.
The Next Big Future describes how it would be easy to capture near earth objects and put them into orbits around the earth for easy mining. Some candidate objects need only 410 meter per second change in velocity for capture if done at the best time for least effort and also a post on the progress to a suitcase size nuclear generator for moon and mars space missions
An ancient star, in the constellation of Leo (The Lion), called SDSS J102915+172927 has astrophysicists scratching their heads, calling for a rethinking of the theory concerning star formation. By ZME Science.
