Falcon 1: The Launch That Reached Orbit

On September 28, 2008, SpaceX's Falcon 1 reached Earth orbit on its fourth attempt. It became the first privately developed, liquid-fueled rocket to do so.

A fourth attempt

SpaceX had tried to launch Falcon 1 into orbit three times before, without success. On September 28, 2008, its fourth flight lifted off from Omelek Island in the Marshall Islands. This time, the rocket reached Earth orbit.

What made the flight historic?

Falcon 1 became the first privately developed and funded liquid-fueled rocket to reach orbit. The flight demonstrated that a private company could build and launch an orbital rocket.

What did it carry?

The rocket carried a demonstration payload called Demosat, also known as Ratsat. It reached orbit, but the payload did not separate from the rocket's second stage.

Why September 28 matters

After three unsuccessful flights, Falcon 1's fourth launch marked a breakthrough for SpaceX and a milestone in commercial spaceflight. The launch happened in the Marshall Islands; its connection to U.S. history is the American company behind the rocket.

Orbit is different from reaching space

A rocket can rise above the atmosphere and still fall back without circling Earth. An orbital launch has to build sufficient sideways speed as well as altitude. Falcon 1’s fourth flight demonstrated that combined requirement, rather than merely reaching a high point.

A milestone with a specific scope

The description “first privately developed and funded liquid-fueled rocket to reach orbit” is deliberately narrow. It should not be shortened to the first private object in space or the first commercial space mission. The qualification identifies the vehicle and development achievement being commemorated.

What the payload proves

NASA’s launch record identifies Demosat, also called Ratsat, as a demonstration payload that remained with the second stage. Reaching orbit and deploying a payload are different outcomes. The launch achieved the essential orbital milestone even though this was not the delivery of a working communications satellite or a crewed mission.
