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?

Orbital ATK to launch robotic servicing mission

The competition heats up: Orbital ATK has signed Intelsat to the first contract for a private robotic servicing mission to defunct commercial communications satellites.

Orbital ATK is offering the Mission Extension Vehicle (MEV), a spacecraft designed to rendezvous with a commercial satellite and dock to the nozzle of its apogee kick motor and surrounding adapter ring. The MEV would then take over propulsion and attitude control for the satellite, offering up to five years of extended life.

Intelsat has agreed to be the customer for the first MEV mission, named MEV-1 and scheduled for launch in 2018. MEV-1 will first dock with a retired satellite in a graveyard orbit above stationary orbit to test its systems, then dock with an active Intelsat satellite to extend its life for five years.

I like the concept. Unlike other much more complicated proposals, which propose to actually refuel the satellite’s original tank, this is simple, quick, and quite doable for relatively little developmental cost. Orbital ATK already as the technology to do the rendezvous, from its Cygnus freighter. All they need to refine is the specific technology to attach to the specific satellites.
