Private space-junk probe gets up-close look at discarded rocket in orbit (photo)

Astroscale Japan has released yet more eye-watering imagery of space debris in Earth orbit.

The Tokyo-based company launched its Active Debris Removal spacecraft (ADRAS-J) atop a Rocket Lab Electron rocket on Feb. 18, 2024. ADRAS-J is designed to test safe methods of approaching and surveying space debris in orbit through what are known as Rendezvous and Proximity Operations, or RPO.

To test the spacecraft’s capabilities, Astroscale sent ADRAS-J to photograph the discarded upper stage of a ********* H-2A

that was launched in 2009. The company released a statement on July 9 showing off a new image of the debris as it floats lifeless above a blue-and-white

with the sun’s glare reflecting off of it.

ADRAS-J took the photograph sometime in June 2024 while just 165 feet (50 meters) away from the bus-sized H-2A upper stage, which measures some 36 feet (11 m) in length and weighs 3 tons.

Aside from taking photographs of the space debris, ADRAS-J used the RPO with the defunct upper stage to demonstrate its collision avoidance system, which includes autonomous operations. In fact, while making the close approach to the rocket body, Astroscale’s spacecraft initiated an autonomous abort when it experienced an attitude (orientation) anomaly.

ADRAS-J was then able to maneuver away from the debris, a capability that demonstrates the spacecraft “can maintain safety even while performing close approach observations of non-cooperative objects,” Astroscale wrote in

.

Remote proximity operations such as these are delicate maneuvers, due to the fact that many space debris objects such as the H-2A’s upper stage are not designed with such missions in mind.

) in which it plans to remove and deorbit a large piece of “non-cooperative” space junk — that is, one that was not designed with such a deorbiting mission in mind.

“This next phase holds significance in addressing the space debris issue and laying the foundation for a sustainable environment for future generations,” Eddie Kato, the president of Astroscale Japan, said in a
