A report in Spaceflight magazine has claimed that the Boeing X-37B is probably spying on China’s Tiangong-1 spacelab as its orbit closely matches the Chinese one.
Spaceflight editor Dr David Baker said with their inclination of 42.78 degrees, both craft will migrate toward or against each other, converging or diverging, roughly every 170 orbits.
Others however thinks that the similar orbits are just a mere coincidence and the X-37B is focused on the Middle East.
