WASHINGTON — Blue Origin has added a fourth customer to its launch manifest for the still-in-development New Glenn rocket.

“We are honored to have SKY Perfect JSAT as a customer for an early New Glenn launch,” Bob Smith, Blue Origin’s chief executive, told SpaceNews. “They are the biggest commercial satellite operator in Asia and highly respected. The whole team at Blue thanks SKY Perfect JSAT for placing its trust in us to take them to orbit.”

The Jeff Bezos-owned company also announced March 12 that mu Space, a Thai startup, finalized its agreement for a geostationary telecom satellite launch, converting a previously announced memorandum of understanding into a binding contract.

“We are looking forward to taking mu Space’s satellite to [geostationary transfer orbit],” Smith said. “They are an innovative company who shares our vision of opening up space for all.”

Sky Perfect JSAT of Tokyo joins mu Space, French fleet operator Eutelsat, and low Earth orbit startup OneWeb in booking New Glenn launches. Counting OneWeb’s five reserved launches, Blue Origin now has eight commercial missions lined up for its New Glenn rocket slated to debut in 2020.

Like Eutelsat’s contract, Sky Perfect JSAT’s contract doesn’t specify what satellite will launch on New Glenn.

Mu Space has yet to select a manufacturer for its satellite, but on March 12 announced a capacity contract on two SES satellites — SES-8 and the yet-to-launch SES-12 — to start providing satellite broadband services in Thailand.

New Glenn is being designed to carry up to 45 metric tons to LEO or 13 metric tons to GTO.

Blue Origin is designing the two-stage New Glenn to provide more lift capacity than SpaceX’s Falcon 9, Arianespace’s Ariane 5, and International Launch Services’ Proton — the three rockets that orbit the majority of the world’s commercial telecom satellites. New Glenn will also have more lift capacity than Europe’s next generation Ariane 6, which debuts in 2020. Only the Falcon Heavy, United Launch Alliance’s Delta 4 Heavy and China’s Long March 5 have larger GTO lift capacities.

Blue Origin is designing New Glenn to be reusable, building on the progress the company has made with the suborbital New Shepard launch vehicle.

Blue Origin is upgrading Cape Canaveral Air Force Station’s Launch Complex 36 to support New Glenn launches, not far from the Florida factory Blue Origin is opening to build the rockets. The company plans to land the vehicle’s first stage on a seafaring drone ship similar to what SpaceX uses to recover its Falcon 9 boosters.
