The Boeing-made Inmarsat 5 F4 communication satellite costing up to $250 million, will dispatch from NASA's Kennedy Space Center on board a 229-foot-tall (70-meter) Falcon 9 promoter at 2321 GMT (7:21 p.m. EDT) on Monday, during a 49-minute dispatch window.
The company, which was described by SpaceX in the mission kit as a "leader and pioneer of mobile satellite communications, Inmarsat has been powering global connectivity for more than three decades", is hoping to provide high-speed broadband to government customers and aviation firms. But because of the size of this launch, the company was unable to do that. The fourth satellite adds further capacity to the GX network, as well as in-orbit redundancy that further upgrades the reliability and resilience of Inmarsat's service offerings. Over the next 90 days, the Inmarsat-5 will use its boosters to maintain its orbit above the Earth at an altitude of 22,300 miles.
Boeing, the American multinational company which manufacturers and sells satellites, has launched the fourth Boeing Inmarsat-5 satellite yesterday.
The mission initiated when the Falcon 9's engine ignited and the rocket achieved lift off.
The payload weighed some 13,500 pounds (6,100 kilograms), and the force needed to propel it to orbit would not leave enough fuel for the rocket to maneuver back to Earth.
Out of the six launches this year, SpaceX managed to recover the first-stage rocket four times.
"It's been a great afternoon and evening".
SpaceX is planning to launch the dragon spacecraft on June 1, which will carry important cargo to the International Space Station.
