The Air Force’s mysterious X-37B space plane is now readying for its third space mission, slated to begin in October. And perhaps not surprising for the hush-hush orbital drone, the third time into space remains as secretive as the first two.
Next month, the X-37B will blast off again aboard an Atlas 5 rocket from Cape Canaveral Air Force Station in Florida. The exact timing of the October launch is unknown and subject to change due to weather conditions, and there’s no telling how long the drone will stay in orbit. ”Preparations for launch at Cape Canaveral have begun,” Major Tracy Bunko, an Air Force spokesperson, told Space.com.
While it’ll be the third flight for the robotic space plane program as a whole, it’s only the second for this particular craft. Four months ago, X-37B’s second of two planes returned from its first flight and a record-breaking 469 days in orbit – more than double the first mission’s total.
Will the OTV-3 try to break that record? The military, naturally, hasn’t said; calls to the Air Force were not immediately returned. Nor does the public know what exactly it’ll be doing once it’s up there. Its mysterious mission has fueled speculation it could be a spy. China fears it could be an experimental weapons platform or a means to disable satellites.
What we do know about the X-37B is that it’s a smaller, unmanned version of the now-retired space shuttle and is ostensibly used for Air Force research missions of an indeterminate nature. The manned space shuttle, we know, was retired last summer and just completed a three-day ferry flight across the United States. The X-37B is like a lighter robotic version, and can stay up for more than a year at a time — far longer than the manned shuttles ever could. The drone measures 29 feet long and 15 feet wide, weighs 11,000 pounds and is about a fourth the weight of the space shuttle, and launches into orbit on a conventional rocket but glides back down to Earth like a plane. Inside the plane is a payload bay roughly the size of a pickup truck bed. It costs around an estimated billion dollars.
The done has also received attention from secretive sources. The National Reconnaissance Office (NRO), America’s secret spy satellite agency, has shown interest in using reusable launch vehicles like the X-37B to carry sensors. Right now the X-37B happens to be the only reusable space plane currently in service by the U.S. military, which narrows the NRO’s options. Via Air Force’s Secret Space Plane Prepped for New Launch
