Space Force’s X-37B will Perform “Never Before-Seen Maneuvers” in Orbit

The X-37B Orbital Test Vehicle (OTV) has been shrouded in mystery since its maiden flight in 2011. Designed by Boeing and operated by the U.S. Space Force (USSF), this remotely operated, reusable space plane is designed to operate in Low-Earth Orbit (LEO), 240 to 800 km (150 to 500 mi) above the Earth, and test reusable vehicle technologies that support long-term space objectives. On December 29th, 2023, the X-37B began its seventh mission (OTV-7) and has reportedly been conducting experiments on the effects of space radiation and testing Space Domain Awareness (SDA) technologies.

As part of this mission, the X-37B will soon begin executing a series of novel maneuvers to change its orbit around Earth. These maneuvers will consist of the spacecraft brushing against Earth’s upper atmosphere to shed speed and lower its orbit without expending much fuel—a technique known as “aerobraking.” This is the first time the X-37B has performed such a maneuver, which will help it evade detection by potentially hostile nations and perform undetected low passes over Earth during future missions.

Falcon Heavy Launches Space Force’s Mysterious X-37B Space Plane

Launch of the X-37B Space Plane aboard the Falcon Heavy

Rocket launches seem to have become a bit mundane for many these days yet the odd launch captures peoples imagination. One such launch took place on 29th December when a SpaceX Falcon Heavy rocket carried an uncrewed and autonomous craft into orbit. The configuration of the Falcon Heavy was such that the boosters landed safetly but the central booster was setup as expendable to carry the plane to its heighest altitude yet but its mission remains a mystery.

China Has its Own Secret Space Plane, and it Just Landed

A lot has changed since the last Space Age. Unlike the days of Sputnik, Vostok, Mercury, and Apollo, the current era is not defined by two superpowers constantly vying for dominance and one-upmanship. More than ever, international cooperation is the name of the game, with space agencies coming together to advance common exploration and science goals. Similarly, there is the way the private space sector has become a major participant, providing everything from launch services and commercial payloads to satellite constellations and crews.

But in some ways, old habits die hard. Since the turn of the century, China has emerged as a major power in space, to the point of becoming a direct competitor with NASA’s human space programs. For the past few years, China has been developing a reusable autonomous spaceplane to compete with the X-37B Orbital Test Vehicle (OTV). Known as Shenlong (“divine dragon”), this spaceplane recently concluded its second test flight after spending 276 days in orbit. Though the details are scant, the Chinese state media company Xinua declared the flight a breakthrough for the Chinese space program.

The X-37B is Back After 908 Days in Orbit. What was it Doing up There? That's Classified

At 5:22 AM Eastern Time on November 12, the Space Force’s (and Air Force’s) X-37B spaceplane landed back on Earth after two and a half years in orbit. The secretive spaceplane has now performed 6 missions, and the latest, OTV-6, was the longest flight yet. Details about the X-37B’s purpose are scarce, though it is clear that the vehicle is designed to serve as a testbed for advanced spaceflight capabilities. Here’s what we know about the latest mission.

China’s New Reusable Spaceplane Lands After 2 Days in Space

On Friday, Sept. 4th, China launched a new and mysterious spacecraft from the Jiuquan Satellite Launch Center. The nature (and even appearance) of the spacecraft remains unknown, but according to statements made by Chinese authorities, it’s a reusable spaceplane. This vehicle is essentially China’s answer to the USAF/USSF X-37B Orbital Test Vehicle (OTV), which made its sixth launch to space (OTV-6) back in late-May.

Russia Just Tested an Anti-Satellite Weapon

The United States and Russia/USSR have been adversaries for a long time. Their heated rivarly stretches back to the waning days of WW2, when the enormous Red Army was occupying large swathes of eastern Europe, and the allies recognized the inherent threat.

The Cold War followed, when the two nations aimed an absurd number of nuclear warheads at each other. Then came the Space Race, when both nations vied for the prestige of making it to the Moon.

The US won that race, but the rivalry didn’t cool down.

The Navy is Testing Beaming Solar Power in Space

Solar power has become a focal point of the battle to mitigate climate change. The potential of solar power is massive – Earth receives as much solar energy in an hour as all of humanity uses in a year. Even with that much energy hitting the Earth, it is only a tiny fraction of the sun’s overall output. Some of that other solar energy hits other planets, but most is just lost to the void of deep space.

There are a number of groups that are leveraging various technologies to capture some of that lost energy. One of the most common technologies being pursued is the idea of the power satellite. Recently, one of those groups at America’s Naval Research Laboratory (NRL) hit a milestone in the development of power satellite technology by launching their Photovoltaic RF Antenna Module (PRAM) test satellite.

Space Force is Starting to Train its Soldiers to Fight… in Space?

On February 19th, 2019, the US Space Force (USSF) was officially created with the signing of Space Policy Directive–4. This effectively broke off from the US Air Force Space Command (AFSC) and made into the sixth and youngest independent branch of the armed forces. Since then, the USSF has established a headquarters, taken on staff from the US Air Force, and even produced a recruitment video!

In their latest announcement, the US Space Force stated that it will begin training soon to develop their staff’s “space warfighting skills.” This will include training personnel to specialize in orbital warfare, electronic warfare, military strategy, and others. The immediate aim is to produce personnel who can control US space infrastructure and protect it from physical, electronic, or digital attacks.

There has been quite a bit of buzz in the past few years about the US Space Force (USSF), especially now that they are recruiting! The sixth and youngest branch of the US Armed Forces, Space Force was created in 2019 when the Air Force Space Command (AFSC) was broken off from the US Air Force (USAF) and made into an independent service branch.

There’s been even more buzz about the USAF’s X-37B Orbital Test Vehicle (OTV), a reusable robotic spaceplane whose official purpose is still highly classified! And now, the USAF and the U.S. Space Force have come together to launch the X-37B on its sixth mission (OTV-6). In just two days, this spaceplane will take off from Cape Canaveral Air Force Station in Florida to perform a number of tasks (some of which we know about!)

The X-37B, the US Air Force’s experimental, Orbital Test Vehicle (OTV) has come back down to Earth after 780 days. It landed at the Kennedy Space Center Shuttle Landing Facility on Oct. 27, 2019, at 3:51 a.m. after breaking its own record for time in space. The X-37B has now spent 2,865 total days in orbit.

The question is, what’s it doing up there?
