Several have been the advances that we have seen in recent years in the exploration of Mars and the dispatch of a potential manned mission. One of the most striking achievements was that put on the red planet to the Curiosity Rover, the little robot Explorer that allowed us to enjoy new data and images of Mars.
NASA invested $ 2,500 million dollars in that mission and in the development and construction of this small vehicle. We can not visit Mars (at least, not short-term) or have in our hands a comparable robot, but the space agency has published plans that allow print the Curiosity Rover in 3D so that we can enjoy a replica of the same.
Other organizations, agencies and entities have also shared numerous designs so that any user can enjoy replica of certain objects in 3D (the British Museum or the Metropolitan Museum of Art are two good examples), but long NASA is one of the pioneers in this segment, and has already released several 3D designs so this type of printers users can enjoy them.
Drawings in STL format of the Curiosity Rover occupy 29.04 MB and have been published by the Jet Propulsion Laboratory. As perpetrators, the Mission of this robot was started on November 26, 2011 and its landing in the crater Gale occurred on August 6, 2012. It was a really accurate shot: the Rover finished just 2.4 km from the planned objective for its landing after a journey of more than 563 million kilometers.
