NASA building space shotgun to blast asteroids
September 21 , 2015
NASA is developing world's first space shotgun that can blast asteroids into small pieces for collection as samples when a robotic spacecraft reaches near one such space rock in the near future.
Along with a Brooklyn-based company Honeybee Robotics, the US space agency is working on a shotgun - as part of its Asteroid Redirect Mission (ARM) - that will test the strength of an asteroid to determine if it is sturdy enough for sampling.
The ARM aims to chop off a massive chunk of an asteroid and shift it into the Moon’s orbit. Then, a manned spacecraft will collect samples and send these back to the Earth for further examination. (Source: IANS)
