The US space launch company Orbital ATK Inc has said it hopes to announce within the next six to eight weeks its first contract for a new “in-space” service using a specialised spacecraft to dock with older satellites and keep them in orbit.The US space launch company Orbital ATK Inc has said it hopes to announce within the next six to eight weeks its first contract for a new “in-space” service using a specialised spacecraft to dock with older satellites and keep them in orbit.

Tom Wilson, vice-president of strategy and business development at Orbital ATK, said the company had invested tens of millions of dollars in the new capability, but gave no specific amount. He also declined to name the customer.Tom Wilson, vice-president of strategy and business development at Orbital ATK, said the company had invested tens of millions of dollars in the new capability, but gave no specific amount.

Wilson said each year about 70 satellites of the 380 communications satellites in orbit could potentially need servicing as they reached the end of the propellant that allows them to maintain their position in space.Wilson said each year about 70 satellites of the 380 communications satellites in orbit could potentially need servicing as they reached the end of the propellant that allows them to maintain their position in space.
Wilson said the company planned to launch its first ViviSat Mission Extension Vehicle (MEV) in 2018, and then carry out its first customer mission in early 2019 after an in-orbit checkout.Wilson said the company planned to launch its first ViviSat Mission Extension Vehicle (MEV) in 2018, and then carry out its first customer mission in early 2019 after an in-orbit checkout.
Orbital ATK eventually plans to operate 10 MEV spacecraft that will be able to dock with other satellites that are running out of fuel, repositioning and controlling them to continue serving their existing areas or move to new areas.Orbital ATK eventually plans to operate 10 MEV spacecraft that will be able to dock with other satellites that are running out of fuel, repositioning and controlling them to continue serving their existing areas or move to new areas.
In seven to eight years, as robotic technology advances, the spacecraft could eventually transfer fuel to ageing satellites, or deliver or swap their payloads, Wilson said, citing work on such capabilities by NASA and other agencies.In seven to eight years, as robotic technology advances, the spacecraft could eventually transfer fuel to ageing satellites, or deliver or swap their payloads, Wilson said, citing work on such capabilities by NASA and other agencies.
Each of the MEV satellites will be designed to last for 15 to 20 years, with the ability to dock and undock from other satellites 10 to 15 times, he said.Each of the MEV satellites will be designed to last for 15 to 20 years, with the ability to dock and undock from other satellites 10 to 15 times, he said.

The capability would eventually allow the government to send larger and heavier payloads into space since it could save the weight of fuel and send that up later.The capability would eventually allow the government to send larger and heavier payloads into space since it could save the weight of fuel and send that up later.
Wilson said the company had been open about its development of the technology, and he did not expect criticism from Russia or China about its potential use to damage other satellites.Wilson said the company had been open about its development of the technology, and he did not expect criticism from Russia or China about its potential use to damage other satellites.

The project was first begun by ATK in 2009, but got fresh momentum after Orbital merged with ATK 18 months ago. Orbital had a satellite that was ideally sized for the job and was docking to other satellites through its Nasa space station cargo resupply contract, Wilson said.The project was first begun by ATK in 2009, but got fresh momentum after Orbital merged with ATK 18 months ago.

Orbital also had a role on a secret US air force programme that was first disclosed last year and included docking capabilities, he said. He declined to provide any additional details.Orbital also had a role on a secret US air force programme that was first disclosed last year and included docking capabilities, he said.
