Working in the Mobile Operations Facility at NASA’s Armstrong Flight Research Center in Edwards, California, NASA Advanced Air Mobility researcher Dennis Iannicca adjusts a control board to capture Automatic Dependent Surveillance-Broadcast (ADS-B) data during test flights. The data will be used to understand ADS-B signal loss scenarios for air taxi flights in urban areas.

Researchers will use the data to understand Automatic Dependent Surveillance-Broadcast (ADS-B) signal loss scenarios for air taxi flights in urban areas. To prepare for ADS-B test flights pilots and crew from NASA Armstrong and NASA’s Glenn Research Center in Cleveland, ran a series of familiarization flights. These flights included several approach and landings, with an emphasis on avionics, medium altitude air-work with steep turns, slow flight and stall demonstrations.

Based out of NASA’s Glenn Research Center in Cleveland, the Pilatus PC-12 is flying over the compass rose in the Roger’s Dry Lakebed at NASA’s Armstrong Flight Research Center, in Edwards, California. The compass rose is more than 4,000 feet in diameter and aligned to magnetic north, to test navigation equipment on aircraft. The Pilatus PC-12 tests communications technology for the emerging Advanced Air Mobility ecosystem. Pilots and crew from both centers perform familiarization flights to prepare for Automatic Dependent Surveillance Broadcast (ADS-B) systems tests between the aircraft and ping-Stations on the ground at Armstrong Flight Research Center. These flights are the first cross-center activity with the Pilatus-PC-12 at Armstrong Flight Research Center.

Equipped with state-of-the-art technology to test and evaluate communication, navigation, and surveillance systems, NASA’s Pilatus PC-12 flies over the Mojave Desert near Armstrong Flight Research Center in Edwards, California. Based at Glenn Research Center in Cleveland, the Pilatus PC-12 runs a series of familiarization flights for NASA Armstrong pilots before a test series evaluating ADS-B or Automatic Dependent Surveillance Broadcast systems for advanced air mobility applications in the desert flight test range on Sept. 18, 2024. Airborne work during familiarization flights includes several approach and landings, with an emphasis on avionics, then medium altitude air-work with steep turns, slow flight, and stall demonstrations to qualitatively understand the handling characteristics of the aircraft. The flights lasted about 60 to 90 minutes on average.

Preparing to Test for Deep Space

A structural steel section is lifted into place atop the B-2 Test Stand at NASA’s Stennis Space Center as part of modification work to prepare for testing the core stage of NASA’s new Space Launch System. The section is part of the Main Propulsion Test Article (MPTA) framework, which will support the SLS core stage for testing. The existing framework was installed on the stand in the late 1970s to test the shuttle MPTA. However, that framework had to be repositioned and modified to accommodate the larger SLS stage. About 1 million pounds of structural steel has been added, extending the framework about 100 feet higher and providing a new look to the Stennis skyline. Stennis will test the actual flight core stage for the first uncrewed SLS mission, Exploration Mission-1.

LADEE Spin Test

During preparations for NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) observatory launch on Sept. 6, 2013, the spacecraft went through final preparations and close-outs, which included checking alignment after its cross-country shipment, checking the propulsion system for leaks, inspecting and repairing solar panels, and final electrical tests. After these activities were completed, more challenging portions of the launch preparations began: spin testing and fueling. To make sure that the spacecraft is perfectly balanced for flight, engineers mounted it onto a spin table and rotate it at high speeds, approximately one revolution per second. The team measured any offsets during the spinning, and then added small weights to the spacecraft to balance it. Once the spacecraft was balanced dry, the team loaded the propulsion tanks with fuel, oxidizer, and pressurant. The spin testing was performed again "wet," or with fuel, in order to see if the balance changed with the full fuel tanks. Engineers from NASA's Ames Research Center in Moffett Field, Calif., have now successfully completed launch preparation activities for LADEE, which has been encapsulated into the nose-cone of the Minotaur V rocket at NASA's Wallops Flight Facility in Virginia. LADEE is ready to launch when the window opens on Friday. Image Credit: NASA ----- What is LADEE? The Lunar Atmosphere and Dust Environment Explorer (LADEE) is designed to study the Moon's thin exosphere and the lunar dust environment. An "exosphere" is an atmosphere that is so thin and tenuous that molecules don't collide with each other. Studying the Moon's exosphere will help scientists understand other planetary bodies with exospheres too, like Mercury and some of Jupiter's bigger moons. The orbiter will determine the density, composition and temporal and spatial variability of the Moon's exosphere to help us understand where the species in the exosphere come from and the role of the solar wind, lunar surface and interior, and meteoric infall as sources. The mission will also examine the density and temporal and spatial variability of dust particles that may get lofted into the atmosphere. The mission also will test several new technologies, including a modular spacecraft bus that may reduce the cost of future deep space missions and demonstrate two-way high rate laser communication for the first time from the Moon. LADEE now is ready to launch when the window opens on Sept. 6, 2013.

NASA Pilatus PC-12 soars over NASA’s Armstrong Flight Research Center in Edwards, California on Sept. 18, 2024.

NASA’s Pilatus PC-12, based out of NASA’s Glenn Research Center in Cleveland, is seen flying over NASA’s Armstrong Flight Research Center in Edwards, California. On Sept. 18, 2024, NASA pilots and crew from both centers flew the PC-12 over the Mojave Desert in a series of familiarization flights. Familiarization flights involve egress training, preflight walkaround, interior preflight, engine start, taxi, and takeoff.
