Thumbs up U.S. Air force’s x-37b space plane nears one year on orbit

CAPE CANAVERAL, Fla. — The fifth, and latest, mission for the U.S. Air Force’s (USAF) X-37B uncrewed space plane nears a milestone that all but one of its predecessors met (and exceeded): one year on orbit.

The secretive spacecraft — also called the Orbital Test Vehicle (OTV), which looks like a miniature Space Shuttle — launched atop a SpaceX Falcon 9 rocket on Sept. 7, 2017, from Launch Complex 39A at NASA‘s Kennedy Space Center, and marked the first time the USAF launched the OTV with a provider other than United Launch Alliance (ULA).

This fifth mission, officially designated OTV-5, had to compete with the weather for its launch window. Hurricane Irma, which would later graze the Florida coast and cause some damage to the launch complex, was targeted to hit the Cape Canaveral area and threatened to scrub the launch as conditions deteriorated ahead of the approaching storm.

Though much of the mission is shrouded in secrecy, some information has been made public. One of the payloads carried aloft is the second version of the Advanced Structurally Embedded Thermal Spreader (ASETS-II). The hardware, designed to test a thermal management system optimized for the space environment, was developed under a program managed by the Air Force Research Laboratory (AFRL) Space Vehicles Directorate at Kirtland Air Force Base in Albuquerque, New Mexico.

Additionally, the vehicle carried with it several small satellites as part of a ride share in order to demonstrate the opportunities that result from quick access to space.

Other information discovered about the mission has come from ground-based observations. As much as the USAF tries to hide the mission of its assets, both amateur and professional skywatchers are quick to figure out where the spaceplane is, even if not knowing what it is doing.

Initially, the spacecraft was deposited in an orbit with an altitude of 220 miles (354 kilometers), and inclined 54.5 degrees to the equator. The highest inclination for any previous mission had been 43.5 degrees, and shows that the USAF is making good on its statement that they will continue to push the boundaries of what the spacecraft can do. The craft has since lowered its orbital altitude to 201 miles (324 kilometers).

“The many firsts on this mission make the upcoming OTV launch a milestone for the program,” stated Randy Walden, the director of the Air Force Rapid Capabilities Office, in a release issued by the USAF. “It is our goal to continue advancing the X-37B OTV so it can more fully support the growing space community.”

Though its landing date has not been stated, it will likely follow the lead of OTV-4 and land at the Shuttle Landing Facility at KSC.

O Almighty Lord God, who neither slumberest nor sleepest; Protect and assist, we beseech thee, all those who at home or abroad, by land, by sea, or in the air, are serving this country, that they, being armed with thy defence, may be preserved evermore in all perils; and being filled with wisdom and girded with strength, may do their duty to thy honour and glory; through Jesus Christ our Lord. Amen.
