Canadarm 2 is one of the most sophisticated technologies currently used on the international space station. Since it was installed on the ISS on April 22nd, 2001, it has been in operation until date. Astronauts aboard the station uses this Canadarm 2 to conduct maintenance check outside the space station. In fact, the arm reduced the need of spacewalk, as it executes a lot of tasks outside the station. If we could build such a sophisticated technology in the early 21st century, imagine what the human civilization will be doing in space in 100 years from now. With the rapid progress made so far in the development of space technologies, may be talking of building technologies to reach the interstellar space in few centuries to come. Here’s how we may achieve interstellar travel in the future.
