Russia gets two contracts for Proton

The competition heats up: Russia has signed two new contracts using its newly announced Proton-Medium rocket configuration.

Both contracts are for the same launch. The primary payload will be a Intelsat communications satellite. The secondary payload will be Orbital ATK’s first Mission Extension Vehicle (MEV-1), which is actually more significant and somewhat ground-breaking.

The MEV-1 provides life-extending services by taking over the propulsion and attitude control functions. Satellites have an average of 15 years of life on orbit, before they need to be replaced. The vehicle itself has a 15-year design life with the ability to perform numerous dockings and undockings during its life span. “Rather than launching new satellites, operators can extend the life of healthy in-orbit satellites, providing enhanced flexibility through Orbital ATK’s scalable and cost-efficient capabilities,” noted Our simple approach minimizes risk, enhances mission assurance, and enables our customers to realize the maximum value of their in-orbit satellite assets.”

The launch of MEV-1 will involve in-orbit testing and a demonstration to be performed with an Intelsat satellite. MEV-1 will then relocate to the Intelsat satellite scheduled for the mission extension service, which is planned for a five-year period. Intelsat will also have the option to service multiple satellites using the same MEV.

If MEV-1 proves successful, Orbital ATK will have built, launched, and made money from the first robot repair satellite. While at first glance this success suggests that satellite companies will need to launch fewer satellites, thus reducing the market demand for rockets, what it will really do is make the orbiting satellite more useful and profitable, thus encouraging new players to enter the market. The demand for satellites will increase, thus increasing the demand for rockets.

Ain’t freedom and private enterprise grand?
