The mysterious X-37B, a secret U.S. military space plane, continues to capture the imagination of the public and aerospace experts. Since its inaugural launch, the device has carried out missions long kept secret by the Pentagon. Now, a rare update from the Space Force reveals fascinating details about an innovative maneuver that could redefine our understanding of military space capabilities. This article explores the implications of this new mission, the strategic importance of the X-37B and its role in the evolution of military space technologies.
A technical feat: the aerobraking maneuver
The aerobraking maneuver performed by the X-37B represents a major technological milestone. By using the drag of Earth’s atmosphere to reduce its orbital speed, this spaceplane manages to save a significant amount of fuel. This technique, often used by scientific missions such as those of NASA around Mars, is being applied for the first time in a military context. The X-37B, after spending more than nine months in a highly elliptical orbit, will begin to plunge into the upper layers of the atmosphere to gradually descend towards Earth.
This process, described as an “innovative space maneuver” by the Space Force, allows the components of the service module to be disposed of in complete safety. Indeed, the X-37B, although designed to land like an airplane, carries a disposable service module that must be disposed of before re-entry. The success of this maneuver highlights the Space Force’s commitment to adopting space-friendly practices by limiting the creation of space debris.
By bringing innovations to the way military spacecraft manage their orbit, the X-37B paves the way for new in-orbit mobility capabilities. This flexibility is crucial for future missions that will require movement between different orbital altitudes and inclinations without relying solely on fuel.. Mastering aerobraking could thus transform the way in which satellites and other space vehicles are managed and deployed.

The mysteries of the current mission
Although the Space Force has provided details about the aerobraking maneuver, the overall objectives of the X-37B’s current mission remain largely shrouded in mystery. Since its launch, the craft has conducted experiments on the effects of radiation and tested space awareness technologies. These activities take place in a highly elliptical orbit that crosses various orbital regimes, including the Van Allen radiation belts.
The secrecy surrounding the X-37B fuels speculation about its true mission. Some experts suggest the device could play a role in monitoring communications, navigation and surveillance satellites, both American and foreign. By flying at altitudes unprecedented for its previous missions, the X-37B demonstrates its ability to operate in varied and potentially hostile environments.
The X-37B’s ability to secretly deploy small military satellites into orbit adds to the aura of mystery surrounding this spacecraft. This versatility, combined with its ability to conduct extended missions without refueling, makes the X-37B a valuable asset to the Pentagon. With flights lasting up to 908 days, this space plane remains a strategic tool with no known equivalent.

The technology behind the X-37B
Built by Boeing, the X-37B is a reusable space vehicle that measures 30 feet long, about a quarter the size of a NASA space shuttle. Although not designed to carry passengers, its advanced design allows for many military applications. The X-37B is equipped with solar panels to generate electricity and has cargo space comparable to the size of a pickup truck bed.
The X-37B’s advanced propulsion technology includes the use of Hall effect motors, which have already been tested on previous missions. These engines provide increased energy efficiency, allowing the device to remain in orbit for extended periods without requiring constant refueling. This autonomy is enhanced by the X-37B’s ability to adjust its orbit using aerobraking, thereby reducing its dependence on fuel reserves.
The X-37B’s ability to carry out varied missions is also explained by its cargo doors, which can open in space to reveal equipment or deploy satellites. This operational flexibility allows the X-37B to fulfill a wide range of tasks, from reconnaissance to technological experimentation. Its robust and adaptable design makes it an essential component of American military space strategy.

Strategic implications for the Space Force
The development of the X-37B capabilities is part of a broader Space Force strategy to enhance the mobility and flexibility of space operations. By allowing spacecraft to move freely between different orbits, the Space Force seeks to ensure strategic superiority in space. This approach aims to minimize constraints imposed by fuel reserves and maximize operational capabilities.
The use of aerobraking as part of this strategy represents a significant step forward. By reducing reliance on traditional thrusters, the Space Force can deploy more complex and adaptive missions. This ability to “maneuver without regret” allows for greater responsiveness to potential threats and changes in the space environment.
Mastery of advanced propulsion technologies and aerobraking techniques could also have civilian applications, particularly in the field of space exploration. By sharing its expertise with scientific missions, the Space Force could contribute to advances in understanding our solar system and beyond. This collaboration between the military and scientific spheres promises to unlock new opportunities for space exploration.
Towards a future of extended missions
The Space Force’s recent announcement marks a turning point in how military space missions are planned and executed. With a focus on sustainability and efficiency, the X-37B is an example of how emerging technologies can transform space operations. By enabling extended missions without refueling, this spaceplane opens the way to new possibilities for the future of military and scientific exploration.
Lessons learned from the X-37B missions could also influence the design of future space missions, both military and civilian. By exploring new techniques to reduce resource consumption while maximizing operational capabilities, the Space Force is committed to promoting a more sustainable approach to space exploration.
As the Space Force continues to expand its capabilities, one question remains: Could the technologies and strategies implemented today in the X-37B missions one day be adapted for larger-scale civilian and scientific use? ? This intersection between military and civilian could well shape the future of space exploration in unprecedented ways.
