Glenn’s Technology Demonstration Convertor (TDC) #13, a free-piston Stirling power convertor, achieved a milestone of 14 years of maintenance-free operation in the Stirling Research Laboratory in building 301. This technology is proving our capability to power spacecraft on longer-duration future scientific missions.

Assembly Milestone Reached as XVS Pallet Installed onto X-59

Following the successful installation of mounting brackets, technicians successfully installed the pallet for the eXternal Visibility System, or XVS, onto the X-59 Quiet SuperSonic Technology X-plane, also known as X-59 QueSST. The pallet installation marks an assembly milestone as the first NASA flight systems hardware to be installed onto the vehicle. X-59 will fly to demonstrate the ability to produce quiet thumps at supersonic speeds, instead of the typical, loud sonic booms associated with supersonic flight.

NASA Dryden director Kevin L. Petersen discusses the center's major milestones during its 60th anniversary celebration in November, 2006.

NASA's Dryden Flight Research Center marked its 60th anniversary as the aerospace agency's lead center for atmospheric flight research and operations in 2006. In connection with that milestone, hundreds of the center's staff and retirees gathered in nearby Lancaster, Calif., in November 2006 to reflect on the center's challenges and celebrate its accomplishments over its six decades of advancing the state-of-the-art in aerospace technology. The center had its beginning in 1946 when a few engineers from the National Advisory Committee for Aeronautics' Langley Memorial Aeronautical Laboratory were detailed to Muroc Army Air Base (now Edwards Air Force Base) in Southern California's high desert to support the joint Army Air Force / NACA / Bell Aircraft XS-1 research airplane program. Since that inauspicious beginning, the center has been at the forefront of many of the advances in aerospace technology by validating advanced concepts through actual in-flight research and testing. Dryden is uniquely situated to take advantage of the excellent year-round flying weather, remote area, and visibility to test some of the nation�s most exciting aerospace vehicles. Today, NASA Dryden is NASA's premier flight research and test organization, continuing to push the envelope in the validation of high-risk aerospace technology and space exploration concepts, and in conducting airborne environmental and space science missions in the 21st century.

SpaceX Recovery Training

On February 28, SpaceX completed a demonstration of their ability to recover the crew and capsule after a nominal water splashdown. This marks an important recovery milestone and joint test. The timeline requirement from splashdown to crew egress onboard the ship is one hour, and the recovery team demonstrated that they can accomplish this operation under worst-case conditions in under 45 minutes. Further improvements are planned to shorten the recovery time even more as the team works to build a process that is safe, repeatable, and efficient.

NASA Stennis Achieves Milestone in Preparation for Future Artemis Testing

Teams at NASA’s Stennis Space Center complete a safe lift and install of an interstage simulator unit needed for future testing of NASA’s exploration upper stage (EUS) in the B-2 position of the Thad Cochran Test Stand. The lift and install, completed over a two-week period that began Oct. 10, marks a milestone for testing the new SLS (Space Launch System) rocket stage that will fly on future Artemis missions to the Moon and beyond. The EUS will undergo a series of Green Run tests of its integrated systems prior to its first flight. During testing, the interstage simulator component will function like the SLS interstage section that helps protect the upper stage during Artemis launches.

Key Lunar Trailblazer Instrument Passes Milestone

The High-resolution Volatiles and Minerals Moon Mapper (HVM³), seen here, is one of two instruments that will be carried aboard NASA's Lunar Trailblazer. Launching in 2023, the small spacecraft – measuring only 11.5 feet (3.5 meters) wide with its solar panels fully deployed – will detect and map water on the Moon's surface to determine its abundance, location, form, and how it changes over time. HVM³ recently completed a significant milestone in a clean room at NASA's Jet Propulsion Laboratory in Southern California. The high-resolution spectrometer measures the infrared light (with wavelengths from 0.6 to 3.6 microns in size) that is absorbed by water. To make sure the instrument is properly aligned, the Trailblazer team cooled HVM3 down to temperatures it will experience in space and made tiny physical adjustments to make sure all the wavelengths of incoming light arrive at the correct locations on the instrument's detector. Figure A shows several members of the Trailblazer team surrounding the instrument – minus its radiator and electronics – mounted on HVM³'s optical bench assembly while undergoing cold alignment. The assembly was placed inside a thermal vacuum chamber and brought to a cold focal plane operating temperature of about minus 240 degrees Fahrenheit (minus 155 degrees Celsius). The team then measured light of different wavelengths across all of the detector's pixels. Based on the data recorded, the team calculated the small adjustments that needed to be made, took the instrument out of the chamber and made those changes, placed it back into the chamber, and then repeated the steps iteratively until HVM³ was in perfect alignment. With this important step complete, a radiator will next be installed to ensure the instrument maintains optimal operating temperatures while Trailblazer is in orbit around the Moon. Then, vibration tests will be carried out to make sure the spectrometer will stay in alignment after the extreme shaking of launch. Lunar Trailblazer was selected to be part of NASA's SIMPLEx (Small Innovative Missions for Planetary Exploration) program in 2019. The mission is led by Caltech in Pasadena, California, and managed by JPL. https://photojournal.jpl.nasa.gov/catalog/PIA25252
