Mysterious US Military Space Plane Begins Advanced Maneuvers in Orbit

In a cutting-edge milestone for orbital innovation, the U.S. military‘s secretive X-37B space plane has begun advanced aerobraking maneuvers to shift its orbit.

Launched on its seventh mission (OTV-7) in December 2023 via SpaceX’s Falcon Heavy rocket, the X-37B has been orbiting the Earth in a highly elliptical path, reaching well beyond the altitude at which satellites normally stay in sync with the planet’s rotation before rapidly closing in near Earth’s atmosphere.

Now, instead of relying on fuel, the space plane is using atmospheric drag to reduce its orbit gradually, a process that could extend mission durations significantly.

Although information has been released about the space plane’s capabilities, much about it remains a mystery, including exactly what it is used for.

Space Force chief: Timing of Chinese spaceplane launch “no coincidence”

China has launched its top-secret military spaceplane for a third time, days after the US military’s winged spacecraft was grounded for several weeks due to problems with its SpaceX rocket.

Observers believe China’s spaceplane looks much like the US military’s X-37B, a reusable craft that Pentagon officials are similarly tight-lipped about. But there’s a distinction in that US officials will publicly discuss, at least in broad terms, the purpose of the X-37B and release images of the spacecraft.

The US military has two X-37Bs in its inventory, each with a cargo bay that could fit a large refrigerator. They resemble small space shuttles, with dimensions about one-quarter those of NASA’s retired shuttle orbiters. The X-37B spaceplanes have flown in space six times, logging missions as long as two-and-a-half years, thanks to deployable solar panels that generate power for greater endurance.

The seventh X-37B flight was supposed to launch this week from Florida, but officials called off the launch to resolve technical issues with its Falcon Heavy rocket.

Then, on Thursday, China sent its own spaceplane aloft on a Long March 2F rocket from the Jiuquan launch base in northwestern China. The Long March 2F is typically used to launch Chinese astronaut crews into orbit but has been modified to accommodate China’s unpiloted robotic spaceplane inside its payload fairing.

Diminutive and mysterious, the Pentagon’s X-37B set to launch again

It’s an itty-bitty spaceplane, not quite 30 feet long and under 10 feet tall, with a pair of stubby wings and a rounded, bulldog-like nose. But despite its diminutive size — it looks like a miniature version of the space shuttle — the Pentagon’s most mysterious spacecraft, known as the X-37B, has built an outsize reputation.

Is it a secretive Pentagon weapon? Is it stealthy? Does it sneak up to satellites? What exactly does it do in space? And why is it up there for so long?

The Pentagon won’t say. And the veil of secrecy over the X-37B continues ahead of its launch Sunday at 8:14 p.m. Eastern on its seventh mission. But this time there are some clues that at least something is different.

The drone, which flies without anyone on board, is to be launched for the first time on SpaceX’s powerful Falcon Heavy, which is more powerful than the rockets that have launched it in the past. That’s led to speculation that the mission will be in a much higher orbit, which appears to be the case according to recent documents. SpaceX won the $130 million contract for the launch in 2018.

Still, what it might do in that higher orbit remains unknown.

The mission has “a wide range of test and experimentation objectives,” is the Pentagon’s official statement. “These tests include operating the reusable spaceplane in new orbital regimes, experimenting with future space domain awareness technologies.”

The reference about “space domain awareness” could mean that it will be keeping an eye on other satellites, potentially watching for threats. Having a better sense of what is going on in the vastness of space — where adversaries’ spacecraft are and what they are doing — has become a key mission of the U.S. Space Force. “Our space systems are threatened by a variety of growing antisatellite capabilities, and the joint force is threatened by increasingly sophisticated adversary space-based systems intended to target the joint force,” Gen. Chance Saltzman, the Space Force’s chief of space operations, said in a statement to Congress earlier this year.

At least one part of the mission is known. The vehicle will “expose plant seeds to the harsh radiation environment of long-duration spaceflight” in an experiment for NASA. In the past, the Pentagon has also used the X-37B to test some of its cutting edge technologies, including a small solar panel designed to transform solar energy into microwaves, a technology that one day could allow energy harnessed in space to be beamed back to Earth.

The Boeing built X-37B has also been used to deploy small satellites, but what those did was also a mystery.

In a surprise move, the military’s spaceplane will launch on Falcon Heavy

The US military’s reusable X-37B spaceplane will launch on the next flight of SpaceX’s Falcon Heavy rocket, scheduled for December 7, officials announced on Wednesday.

This was unexpected because the spaceplane’s six previous missions launched on medium-lift Atlas V or Falcon 9 rockets. This next mission, the seventh by an X-37B spaceplane, will fly on a heavy-lift launcher for the first time.

The payload for the next Falcon Heavy rocket was a secret before the military’s announcement on Wednesday. The mission was known simply by the designation USSF-52, and it will take off from NASA’s Kennedy Space Center in Florida.

In a statement, the Space Force said the seventh X-37B mission will have a “wide range of test and experimentation objectives.” The Pentagon wants everyone to know the X-37B spaceplane exists, but military officials are mum about the details of the vehicle’s missions. The Space Force’s statement Wednesday was similarly vague on details of the upcoming flight.

“These tests include operating the reusable spaceplane in new orbital regimes, experimenting with future space domain awareness technologies, and investigating the radiation effects on materials provided by NASA,” the Space Force said.

Shrouded in secrecy, the automated X-37B spaceplane can deploy small satellites, host experiments, and pursue other classified objectives. Flying without any astronauts on board, the vehicle generates electricity with a solar array and autonomously guides itself to a runway landing at the end of each mission.

The Space Force Has Created an “Orbital Warfare” Unit, and Now Has Its Own Spaceship

It’s not specifically a TIE fighter or X-Wing from the “Star Wars” series, but The Drive reported last week that Trump’s recently created Space Force is now in charge of the experimental X-37B spacecraft. A craft that was prior in the ownership of the Air Force, which should turn many heads.

The unit is also precariously known as Delta 9, according to the service. Military.com reports:

Space Operations Command was activated last month during a ceremony at Peterson Air Force Base, Colorado. Under the field commands are deltas and squadrons, according to the Space Force’s command hierarchy.

Delta 9’s Detachment 1 “oversees operations of the X-37B Orbital Test Vehicle, an experimental program designed to demonstrate technologies for a reliable, reusable, unmanned space test platform for the U.S. Space Force,” according to the unit’s fact sheet.

Delta 9 consists of three active-duty squadrons headquartered at Schriever Air Force Base, Colorado: 1st Space Operations Squadron, 3rd Space Operations Squadron and 750th Operations Support Squadron, along with Detachment 1. The three squadrons conduct “protect-and-defend operations from space and provide response options to deter and defeat adversary threats in space,” according to the chart.
