Pentagon Issues Uncommon Update on X-37B Spaceplane Initiative

# The X-37B Spaceplane: Unveiling the Secrets of a Covert Mission

The X-37B spaceplane, a top-secret vehicle run by the U.S. Space Force, has been enveloped in intrigue for years. Details regarding its missions are seldom disclosed, and the Pentagon generally opts for silence during the operations of the spaceplane. Nevertheless, a recent statement from the Space Force has illuminated aspects of the mysterious vehicle’s latest mission, offering a rare insight into its functionalities and operations.

## A Craft That Keeps Rivals Uncertain

The X-37B is a reusable, autonomous spaceplane that has been engaged in confidential missions since its inaugural flight in 2010. This spacecraft is engineered for low-Earth orbit (LEO), yet its specific mission objectives have remained classified. What stands out is that the X-37B’s capacity to maneuver and alter its orbit renders it an invaluable tool for the U.S. military.

Among the prominent benefits of the X-37B is its unpredictability. A military spokesperson observed, “When it’s near the Earth, it’s sufficiently close to the atmosphere to change direction. Thus, our adversaries are left guessing—and this occurs on the opposite side of the Earth from them—where it will emerge next. And it’s well known that drives them crazy. And I’m quite pleased about that.”

This capability to shift its orbit and stay unclear is a crucial strategic benefit. The X-37B can vanish from radar and reemerge elsewhere, complicating adversaries’ efforts to monitor its trajectory and anticipate future endeavors. This unpredictability frustrates foreign nations, who remain uninformed regarding the spaceplane’s intentions and positions.

## Lifting the Veil: An Uncommon Update

The Pentagon’s choice to share an update about the X-37B during its seventh mission was unexpected. In the past, military officials have only provided minimal information ahead of a mission launch and then become tight-lipped until the spaceplane lands back on Earth. The ongoing secrecy surrounding the X-37B’s activities has spurred conjecture and fascination among enthusiasts and analysts of space.

However, in February, a significant breakthrough occurred when a satellite-tracking hobbyist detected the X-37B in orbit. By noticing sunlight bouncing off the spacecraft, the hobbyist was able to ascertain that the spaceplane was operating at a considerably higher altitude compared to earlier missions. Follow-up observations established that the X-37B was in a highly elongated orbit, ranging from 300 to 38,600 miles (186-by-23,985 miles) above the Earth, inclined at 59.1 degrees to the equator.

This marked a notable shift from the spaceplane’s earlier missions, which were limited to low-Earth orbit, just a handful of hundred miles above the surface. Discovering the X-37B’s new orbital route raised inquiries about the spacecraft’s activities in this altitude and how it would eventually return to its home planet.

## A Mission in an Elongated Orbit

The recent announcement from the Space Force clarified some details. Military officials stated that the X-37B’s current mission entails executing radiation effect experiments and assessing space domain awareness technologies in a highly elliptical orbit. This orbit leads the spaceplane through the Van Allen radiation belts, regions of intense radiation surrounding Earth, while intersecting several orbital zones populated by U.S. and international communications, navigation, and surveillance satellites.

The Van Allen belts pose substantial challenges to spacecraft due to elevated radiation levels. By traversing these belts, the X-37B is likely evaluating radiation effects on various technologies and materials, which could have significant implications for future space endeavors, particularly those involving human operators.

In addition to radiation studies, the X-37B is engaged in testing technologies dedicated to space domain awareness. This concept involves the capability to identify, monitor, and track objects in space, including satellites and debris. With the increasing number of entities in Earth’s orbit, maintaining situational awareness of the space environment is becoming increasingly vital for national security and safeguarding key assets in space.

## Experimenting with Advanced Technologies

The X-37B has a record of trialing advanced space technologies. In prior missions, the spaceplane has assessed a Hall-effect ion thruster, an electric propulsion mechanism that utilizes ions for thrust generation. This technology could be advantageous for prolonged space missions, offering greater efficiency than conventional chemical engines.

In addition to propulsion experiments, the X-37B has covertly deployed small military satellites into orbit. These satellites may serve various purposes, encompassing communications, surveillance, and reconnaissance. The ability to launch satellites from the X-37B adds further versatility to the vehicle’s operational capabilities.

Doctors Caution Breakdancers About Possible “Headspin Hole” Injury Hazards

### Breakdancing and the “Headspin Hole”: An Uncommon Injury in the Dance Realm

Breakdancing, often referred to as breaking or b-boying, has transformed from its origins on the streets of New York City in the 1970s into a worldwide cultural sensation. From grassroots competitions to its official inclusion in the 2024 Summer Olympics, breakdancing has enthralled dancers and spectators across the globe. Nevertheless, the dance style’s physically challenging moves and energetic performances introduce a distinctive array of obstacles for its enthusiasts, including a unique injury known as the “headspin hole” or “breakdance bulge.”

This ailment, marked by a noticeable bump on the scalp, results from repeated headspins, a highly recognizable and physically demanding power move in breakdancing. A recent case study featured in the *British Medical Journal* (BMJ) provides insights into this rare yet increasingly acknowledged injury, exploring its origins, frequency, and potential treatments.

### The Growth of Breakdancing and Its Physical Challenges

Breakdancing is an energetic dance genre that fuses acrobatic maneuvers, detailed footwork, and gravity-defying rotations. Among its most visually striking techniques are power moves, which typically involve the dancer rotating on various body parts, including their head. Headspins necessitate that the dancer balance their entire weight on the crown of their head while spinning at rapid speeds. Although this maneuver is a crowd favorite, it also imposes significant stress on the scalp, skull, and neck.

As breakdancing has surged in prominence, the frequency of dancers suffering from overuse injuries has also increased. These injuries often arise from repetitive strain on certain body areas, especially the head, neck, and shoulders. A 2009 German study involving 106 breakdancers indicated that 60.4 percent of those surveyed reported overuse injuries to the scalp as a result of headspins. Among these individuals, 31.1 percent experienced hair loss, 23.6 percent developed bumps on their heads, and 36.8 percent faced scalp inflammation. A more current 2023 study focusing on 142 breakdancers discovered that those practicing headspins more than three times weekly were significantly more prone to hair loss.

### The Illustration of the “Headspin Hole”

One particularly notable instance of headspin-related injuries is featured in a recent case study authored by Mikkal Bundgaard Skotting and Christian Baastrup Søndergaard from Copenhagen University Hospital in Denmark. This case involved a male breakdancer in his early 30s, who had been honing his craft for 19 years. His training was rigorous, with sessions lasting 90 minutes, five days a week. Headspins were routinely included in his workouts, with each session comprising intervals of spinning on his head lasting anywhere from two to seven minutes.

Over the past five years, the dancer observed a significant bump forming on the top of his head, along with increasing tenderness. Worrying about the escalating size of the lump, he sought medical assistance. An MRI scan indicated considerable thickening of the scalp tissue and skull in the impacted area, leading the medical team to propose surgical intervention.

During the operation, doctors excised the mass and examined it. The results confirmed that the lump was the consequence of recurrent trauma to the scalp and skull due to the dancer’s frequent headspins. The thickened tissue and bone were likely the body’s reaction to the relentless pressure and friction, resulting in what is now termed the “headspin hole.”

### Comprehending the “Headspin Hole” Phenomenon

While the “headspin hole” may appear to be an atypical injury, it is not entirely unexpected considering the mechanics involved in the headspin maneuver. During this move, the dancer’s head makes direct contact with the flooring, often lacking adequate cushioning or protection. The friction between the scalp and floor, combined with the spinning motion, may result in irritation, inflammation, and ultimately, thickening of the tissue.

With prolonged exposure, this recurrent stress can cause a protruding lump to form on the scalp, which may become uncomfortable or tender. In certain situations, the bone beneath may also thicken, as observed in the case presented by Skotting and Søndergaard. This condition resembles other overuse injuries experienced by athletes, such as “runner’s knee” or “tennis elbow,” where consistent movements lead to localized damage and alterations in the tissue.

### Preventing and Addressing Breakdancing Injuries

Although breakdancing injuries like the “headspin hole” are relatively uncommon, they underscore the necessity for injury prevention and effective training practices among dancers. Here are several strategies that can aid in minimizing injury risks:

1. **Protective Equipment**: Utilizing padded headgear or specialized caps can lessen the friction and strain on the scalp during headspins. This can help avert irritation and reduce the likelihood
