2020 is set to see history made with the first ever servicing operation on an in-orbit satellite. Robotic orbital troubleshooters, which are expected to pave the way for a new era of space robotics, will one day shuttle malfunctioning spacecraft back and forth, refuel them, perform basic repairs or serve as temporary propulsion and steering units. The present paper looks at Space Logistics' MEV-1 (Mission Extension Vehicle-1) in particular, together with its mission to rendezvous with Intelsat IS901 and boost it into an orbit which will enable it to operate for a further five years. After five years, Intelsat IS901 will then be sent into a graveyard orbit and MEV-1 will move on to another satellite. Also mentioned is the work being carried out by Effective Space to carry out servicing and other life-extension services.
