WASHINGTON — The U.S. Air Force Research Laboratory has opened a lab focused on developing materials for new deployable space structures.
Construction on the Deployable Structures Laboratory, or DeSel, began in December 2019 and opened Oct. 29, 2020. Scientists and engineers moving into the $4 million lab at Kirtland Air Force Base, New Mexico, will continue the work of the Spacecraft Component Technology Center of Excellence, which has a history of developing spacecraft structure materials.
DeSel contains specialized equipment and a climate-controlled, vibration-isolated laboratory capable of testing spacecraft structures up to 20-by-15 meters, allowing AFRL to further research and develop high-strain composite materials.
“I'm excited to have a facility that was specifically built for testing novel deployable space structures,” Benjamin Urioste, research engineer and lead for the Integrated Structural Systems team, said in a statement. “With the push toward hybrid architecture and smaller satellites, high packing efficiency structures and the ability to bring large satellite capability to small satellites is more important than ever.”
“This new class of high strain composite enabled structures requires new ground test facilities,” he added. “Satellite deployments are nerve-wracking, one-shot endeavors and the high-fidelity ground testing that will take place in the DeSel is critical to ensuring on-orbit success.”
Spacecraft Technologies Division chief Mark Roverse said the structures, made possible by high strain composites, "will enable new mission paradigms for the U.S. Space Force.”
“AFRL has led development of high strain composites for deployed spacecraft structures, and we are excited to see the new mission capabilities that are being enabled,” Roverse added.
One spacecraft in development that will benefit from these new structures is AFRL's Space Solar Power Incremental Demonstration and Research project. With the SSPIDR project, the lab wants to build a spacecraft capable of collecting solar energy on orbit and then transmitting that energy to forward-operating bases via radio frequency.
Northrop Grumman was awarded a $100 million contract to support space-based experiments informing SSPIDR's development.
The Space Force is testing that technology on the X-37B, the service's secretive spacecraft, but DeSel's work will provide the materials needed to build the SSPIDR craft.
“This innovative research will help us to deliver the essential energy our warfighters need at the right place at the right time,” explained Col. Eric Felt, director of the AFRL's Space Vehicles Directorate. “Some of the first structures that we look forward to testing in this new lab are those required for our Space Solar Power Incremental Demonstration and Research (SSPIDR) project, one of our top priority programs.”

By: Ben Werner ARLINGTON, Va. – Balancing the desire to build the Navy the nation needs with the ability to fight with the fleet the nation has is at the core of the mission of U.S. Fleet Forces Command mission, its commander said on Thursday. The Navy's high-end warfare plan – dubbed Distributed Maritime Operations (DMO) – relies on fleet commanders considering future technologies, integrating new capabilities into existing systems and provided the right level of manning. In the meantime, commanders need to fight with the equipment and manning they currently have, a task complicated by uneven funding levels Fleet Forces commander Adm. Christopher Grady said at the Surface Navy Association Symposium. “Seventy five percent of the fighting force today will be what we fight with in 2030,” Grady said. “We must sustain what we have now to defend our interests in the future.” Grady said the demand for maintenance capability is outpacing the industrial base's growth rate. At risk, he said, is the industrial base's ability to build new ships while keeping current ships in operations. “Right now, the industrial base is optimized for cost efficiency,” Grady said. In an era of renewed great power competition the Navy and industrial base needs to rethink how to work some flexibility into how quickly shipbuilders and maintainers can adjust their operations, Grady said. “At issue is how do we grow our capacity for both maintenance and modernization,” Grady said. “This is challenging.” As an example, many of the critical parts the Navy relies on are from sole-source suppliers, Grady said. Then there are the firms that could bid on Navy projects but don't because of various barriers making it difficult or impossible to submit competitive bids. Since 2000 the entire defense industrial base lost more than 20,500 contractors, according to a Pentagon report released in September. The shipbuilding industry took a particularly hard hit and growing that sector is key to building the 355-ship fleet, the report said. “Expanding the number of companies involved in Navy shipbuilding is important to maintaining a healthy industrial base that can fulfill the 355-ship fleet and support the Navy's long-range shipbuilding plan,” the report said. Changing how the industrial base and Navy interact is a critical part of solving the building and maintenance capacity issues, Grady said. He wants the Navy's interaction with industry to seen as a partnership. One example he proposed was buying portable dry docks that could be moved and leased to shipyards. More shipyards could bid on work by removing what Grady said is a significant barrier to entry into the marketplace – the significant capital investment required to handle Navy maintenance work. “The ideal would be to come to the table and share notes,” Grady said. “What can we do for each other that's good for the nation.” https://news.usni.org/2019/01/17/navy-and-industry-must-balance-new-construction-with-maintaining-existing-platforms
