By Bradley Hicks AEDC Public Affairs

Thanks to advancements made in the wake of then U.S. Air Force captain and test pilot Chuck Yeager shattering the sound barrier in 1947, a new generation of aircraft was pushing the speed enve- lope like never before by the mid-1960s. The benefits of such progress were obvious but also gave rise to new con- cerns. Engineers were working with never-before-seen speeds and configura- tions. The question of whether munitions could be safely released from faster-than- ever aircraft needed to be answered, es- pecially with America in the midst of the Vietnam War. The weapons themselves were also changing. The use of gravity-guided “dumb bombs” was giving way to guided bombs, allowing increased accuracy. To aid in the development of new weapons and to ensure stores could be released safely from high-speed aircraft, a new wind tunnel was constructed at Arnold Air Force Base. That addition to the Flight Systems Combined Test Force reached a major milestone earlier this year.

By Deidre Ortiz AEDC Public Affairs

As part of an educational outreach effort during Inter- national Bat Week held Oct. 24-31, U.S. Fish and Wild- life Service and Arnold Air Force Base biologists held presentations at the Hands-On Science Center in Tullaho- ma and on base to provide information on bats and how they play a vital role in the environment. The 2018 theme for International Bat Week asked ev- eryone to “Be a Bat Hero.” Many federal agencies, uni- versities and nonprofit organizations celebrated around the nation and internationally to share the plight of imper- iled bats and explain how everyone can “be a bat hero” and help bats locally and globally. Leslie Hay, a USFWS biologist at Arnold, along with Sarah Harrison, USFWS Tennessee Field Office biolo- gist, and Shannon Allen, chief of National Environmental Policy Act, Natural and Cultural Resources, worked with Arnold Science, Technology, Engineering and Math- ematics (STEM) director Olga Oakley to provide a “Cel- ebration of Bats” to a group of homeschooled students recently visiting the HOSC. “The students learned about bat ecology, bat conser- vation, threats to bats such as White-Nose Syndrome, and activities that families can do to help bats, like construct- ing bat houses and planting bat gardens,” Hay said. “Ten- nessee Wildlife Resources Agency, another partner in Leslie Hay, U.S. Fish and Wildlife Service liaison at Arnold Air Force Base, shares information with Arnold the fight for bat conservation, provided a ‘Bat Education team members during International Bat Week by setting up a display at Café 100 in the Administration and Engineering Building on Oct. 31.

EDWARDS AIR FORCE BASE, Calif. – There’s no better way to learn about testing com- plex things than visiting Edwards AFB. That’s why the 412th Test Wing hosted a forum to discuss space test and evaluation Oct. 29. The day-long discus- sions included colonels from Air Force Space Command, Air Force Test Center, 412th TW, Arnold Engineering and Develop- ment Complex (in Tennes- see), U.S. Air Force Test Pilot School and Head- quarters, Air Force Test and Evaluation. The focus of the visit was the requirements need- ed for test and evaluation of Air Force space-based assets and what collabora- tion opportunities can exist between Air Force Space Command and the Air Force Test Center located at Edwards. “Acquisition of space- based assets requires de- Frank Dones, 412th Range Squadron director of operations (right), discusses the squadron’s capabilities with Air Force colonels vis- tailed test and evaluation in iting Edwards to gain insight on test and evaluation execution and education, as well as how they can work with Edwards on future order to field systems that space test and evaluation programs.

By Laura Rochol NASA

CAPE CANAV- ERAL, Fla. - The pow- erhouse that will help NASA’s Orion spacecraft venture beyond the Moon is stateside. The Europe- an-built service module that will propel, power and cool during Orion flight to the Moon on Exploration Mission-1 arrived from Germany at the agency’s Kennedy Space Center in Florida on Tuesday to begin final outfitting,- in tegration and testing with the crew module and other Orion elements. The service module is integral to human missions to the Moon and Mars. After Orion launches on top of the agency’s Space Launch System rocket, the service module will be responsible for in-space maneuvering through- out the mission, includ- ing course corrections. The service module will also provide the powerful burns to insert Orion into lunar orbit and again to get out of lunar orbit and return to Earth.
