4th launch for mysterious X-37B mini-shuttle

I’ve said it before (here here here here): you can never have too many robot space planes.

Space.com reports that the 4th mission of the X-37B will launch from Cape Canaveral on May 20.  Statement reveal a little more leg this time – if you believe the statement.

The X-37B’s payloads and specific activities are classified, so it’s unclear exactly what the spacecraft does while zipping around the Earth. But Air Force officials have revealed a few clues about the upcoming mission.

“The Air Force Research Laboratory (AFRL), Space and Missile Systems Center (SMC) and the Air Force Rapid Capabilities Office (AFRCO) are investigating an experimental propulsion system on the X-37B on Mission 4,” Capt. Chris Hoyler, an Air Force spokesman, told Space.com via email.

“AFRCO will also host a number of advance materials onboard the X-37B for the National Aeronautics and Space Administration (NASA) to study the durability of various materials in the space environment,” Hoyler added.
