SPACE FORCE has been gearing up for the X-37B model plane to take it’s highest test flight to date.

The X-37B model plane has been dubbed a secret space plane and is set to launch using a SpaceX Falcon Heavy rocket on December 10.

The first five launches of the space shuttle were done using an Atlas V rocket, but has since switched to the Falcon system for trips six and now seven.

The Falcon Heavy has three Falcon 9 cores, with 27 engines in all generating five million pounds of thrust.

With the amplitude of this power, it is expected that X-37B will be taking its highest flight yet.

It is believed that there are two of these planes in existence.

Built by Boeing, the X-37B is similar to previous space shuttles in many mechanical and functional manners, but has a key difference.

This new model is considerably smaller, so small that it could fit in the payload bay of an older modeled space shuttle.

December 10 will mark the seventh launch for the space plane (OTV-7), its first having been in 2010.

OTV-7 of the X-37B is set to launch at 8:14 pm EST from the Kennedy Space Center in Florida.

With six successful launches, the X-37B has spent nearly 3,774 total days in space; 908 days being the longest consecutive day trip.

“This seventh flight of the X-37B continues to demonstrate the innovative spirit of the United States Space Force,” said Secretary of the Air Force Frank Kendall.

Official statements have revealed that “test new orbital regimes,” are planned to be tested as well.

Previous launches have had different focuses, including providing an “opportunity to launch a spacecraft designed and operated by cadets at U.S. Air Force Academy.”

Other launches have also used Naval Research Laboratory technology to test collecting solar energy and sending it to the ground.

X-37B space flights have also been used to study the “effects of long-duration space exposure,” on organic matter for Nasa research.

OTV-7 has been said to be testing more “space domain awareness technologies,” but the nature of those technologies is mostly classified.

It has been divulged that this trip intends to test the effect of radiation on materials provided by Nasa; some expect the materials to be seeds as a part of the Seeds-2 project.
