The GOES spacecraft continues its processing at the Astrotech Facility in Titusville, Fla. and fuel was loaded into the GOES-P spacecraft on Saturday, January 30. The fuel will keep GOES-P in orbit for about 14 years.
Just as you wouldn't want your car's gas tank to leak, engineers don't want a satellite to leak fuel. So, a team of engineers performed propulsion system pressurization and leak checks before fueling GOES-P. Those preparations were completed on January 22.
The GOES-P spacecraft was moved to the fueling stand and the team began fueling the spacecraft. The oxidizer was successfully loaded on January 28. Like a fire needs oxygen to burn, the spacecraft fuel needs the oxidizer to ignite in space, where there is no air. . The fuel was successfully loaded on January 30.
After carefully lifting and moving the fueled spacecraft, the team successfully mounted GOES P on top of the Delta IV Payload Attach Fitting (PAF). This was completed on February 1. The PAF is a conical shape structure that the spacecraft mounts onto inside the launch vehicle. The spacecraft rides on the PAF until it separates at approximately 22 thousand miles above the Earth's surface.
