The U.S. Air Force's robotic X-37B space plane has quietly passed the five-month mark on its latest secret mission in Earth orbit.

The unmanned X-37B spacecraft launched into space atop an Atlas 5 rocket from Florida’s Cape Canaveral Air Force Station on Dec. 11, 2012, kicking off a mission whose objectives and payloads are classified.

The winged craft is known as Orbital Test Vehicle-3 (OTV-3), since it is conducting the third mission of the Air Force's X-37B program.

What OTV-3 is up to on its confidential cruise remains unknown.

However, a network of vigilant skywatchers is monitoring the mission as it progresses.

"It’s certainly important not to forget about these programs," said Ted Molczan of Toronto, a leader in the worldwide community of satellite trackers.

"Careful observation over a long time may provide the clues to finally solve the mystery."

Molczan said that, even then, he suspects that any breakthrough in knowledge regarding X-37B’s orbital missions will more likely result from leaks by insiders to journalists.

"Hobbyist observations can provide corroboration and some interesting, even useful details, but seldom are sufficient to expose the big picture…especially with new programs," he reported. "With X-37B, we can only watch and wait."
