The U.S. Air Force's X-37B space plane has winged past 200 days in orbit on its latest clandestine mission.
That mission, known as Orbital Test Vehicle-5 (OTV-5), began Sept. 7, 2017, when the robotic spacecraft launched atop a SpaceX Falcon 9 booster from NASA's Kennedy Space Center (KSC) in Florida.
According to Air Force officials, one payload flying on OTV-5 is the Advanced Structurally Embedded Thermal Spreader, or ASETS-11, of the U.S. Air Force Research Laboratory (AFRL). This cargo is testing experimental electronics and oscillating heat pipes for long durations in the space environment.
Dual-use tech
"The X-37B has been and remains a technology demonstrator," said Joan Johnson-Freese, a professor in the National Security Affairs Department at the Naval War College in Newport, Rhode Island.
"Given that most space technology is dual-use, with the ever-increasing sway toward warfare in space, it's likely that the more militaristic uses of the space plane will be pursued more vigorously, and likely openly given the [presidential] administration's proclivity toward chest thumping," she told Space.com, expressing her personal view.
