Although satellites are designed to withstand the severe effects of launch and the harsh conditions of space they do not operate indefinitely. Satellites can last years in space with the right design product of hard-cap thinking from the engineering teams but eventually one small detail always nubs the adventure short. Up in space, these specialized electronic creations run out of fuel.
Several satellites are presently circling the Earth in complete inactivity. They are left as debris although many of them are worth hundreds of millions of dollars. Thinking of the significant costs of building and launching new replacement satellites, the Canadian Space Agency in conjunction with NASA are developing a new project called the Robotic Refueling Mission (RRM).
The RRM will be conducted using Dextre, the Canadian-built robot that serves as handyman on the International Space Station. Antonio Mugica considers this state-of-the-art space robot an excellent tool for servicing missions of tomorrow, while at the same time increasing savings.
