The division plays a key role in ensuring the effectiveness and efficiency of space operations, providing essential business support such as programmatic integration, strategic planning, information technology and cybersecurity leadership, stakeholder outreach, and administrative services.
Before her current role, Oglesby led the business management function for NASA’s Commercial Crew Program at NASA’s Kennedy Space Center in Florida. She had a front-row seat to history during NASA’s SpaceX Demo-2 mission, which successfully launched astronauts to the International Space Station in the first commercially built and operated American rocket and spacecraft, marking a significant milestone in NASA’s space exploration efforts.
“It was an honor of a lifetime,” she says, reflecting on her role in this historic achievement.
Oglesby’s ability to foster teamwork and genuine care for others has been a hallmark of her career, whether serving in NASA’s Commercial Crew Program or now guiding the Strategic Integration and Management Division.
While reflecting on her new role as division director, Oglesby is most excited about the people. As someone who thrives on diverse activities and complex challenges, she looks forward to the strategic aspects of her role and the opportunity to lead a dynamic team helping to shape NASA’s future.
The future is bright. We are actively building the future now with each choice as part of the agency's strategic planning and transition from current International Space Station operations to the new commercial low Earth orbit destinations.
Diana Oglesby
Director, Strategic Integration and Management Division, Space Operations Mission Directorate
“The future is bright,” said Oglesby. “We are actively building the future now with each choice as part of the agency’s strategic planning and transition from current International Space Station operations to the new commercial low Earth orbit destinations.”
While Oglesby is deeply committed to her work, she also believes in “work-life harmony” rather than a work-life balance, by giving her attention to the sphere of life she is currently in at that moment in time. She remains ever focused on harmonizing between her NASA duties and her life outside of work, including her three children. Oglesby enjoys spending time with her family, baking, crafting, and participating in her local church and various causes to support community needs.
Known for her positive energy, passion, and innovation, Oglesby always seeks ways to improve systems and make a difference in whatever project she is tackling. Her attention to detail and problem-solving approach makes her an invaluable leader at NASA.
NASA’s Space Operations Mission Directorate maintains a continuous human presence in space for the benefit of people on Earth. The programs within the directorate are the heart of NASA’s space exploration efforts, enabling Artemis, commercial space, science, and other agency missions through communication, launch services, research capabilities, and crew support.

Johnson Space Center Vibration Test FacilityNASA Nov. 14, 2024
NASA Johnson Invites Proposals to Lease Vibration Test Facility
NASA’s Johnson Space Center is seeking proposals for the use of its historic, but underused, Vibration and Acoustic Test Facility. Prospective tenants must submit facility walk-through requests by Monday, Nov. 18.
Final proposals are due by 12 p.m. EST Monday, Dec. 16, and must promote activities that will build, expand, modernize, or operate aerospace-related capabilities at NASA Johnson and help preserve the historic and iconic building through preservation and adaptive reuse.
NASA plans to sign a National Historic Preservation Act (NHPA) lease agreement for the facility, also known as Building 49, for a five-year base period and one five-year extension to be negotiated between NASA and the tenant. To request a walk-through, send an email to hq-realestate@mail.nasa.gov.
“This historic facility has been used for decades to ensure the success and safety of all human spaceflight missions by putting engineering designs and hardware to the ultimate stress tests,” said NASA Johnson Director Vanessa Wyche. “For more than 60 years, NASA Johnson has been the hub of human space exploration and this agreement will be a vital part of the center’s efforts to develop a robust and durable space economy that refines our understanding of the solar system and space exploration.”
All proposals must adhere to the guidelines detailed in the Agency Announcement for Proposals describing concept plans for development of the property, including any modifications proposed to the building; a statement of financial capability to successfully achieve and sustain operations, demonstrated experience with aerospace-related services or other space-related activities, and a detailed approach to propelling the space economy.
The nine-story building complex has a gross square footage of 62,737 square feet and consists of a north wing measuring 62 feet long, 268 feet wide and 106 feet tall, and a central wing about 64 feet long and 115 feet wide. Building 49 currently houses five laboratories, including the General Vibration Laboratory, Modal Operations Laboratory, Sonic Fatigue Laboratory, Spacecraft Acoustic Laboratory, and Spacecraft Vibration Laboratory. The south administrative portion of the building is not included in the property offered for lease.
As the home of Mission Control Center for the agency’s human space missions, astronaut training, robotics, human health and space medicine, NASA Johnson leads the way for the human exploration. Leveraging its unique role and location, the center is developing multiple lease agreements, including the recently announced Exploration Park, to sustain its key role in helping the human spaceflight community foster a robust space.
In the coming years, NASA and its academic, commercial, and international partners will see the completion of the International Space Station Program, the commercial development of low Earth orbit, and the first human Artemis campaign missions establishing sustainable human presence on the Moon in preparation for human missions to Mars.
Johnson already is leading the commercialization of space with the commercial cargo and crew programs and private astronaut missions to the space station. The center also is supporting the development of commercial space stations in low Earth orbit, and lunar-capable commercial spacesuits and lunar landers that will be provided as services to both NASA and the private sector to accelerate human access to space. Through the development of Exploration Park, the center will broaden the scope of the human spaceflight community that is tackling the many difficult challenges ahead.

Updates on NASA Field Campaigns
Snippets from The Earth Observer’s Editor’s Corner
PACE-PAX
PACE–PAX had as its primary objective to gather data to validate measurements from NASA’s PACE mission. A secondary objective was validation of observations by the European Space Agency’s recently launched Earth Cloud, Aerosol, and Radiation Explorer (EarthCARE) mission. The operations spanned Southern and Central California and nearby coastal regions, logging 81 flight hours for the NASA ER-2, which operated out of NASA’s Armstrong Flight Research Center (AFRC) in Edwards, CA, and 60 hours for the Twin Otter aircraft, which was operated by the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) at the Naval Postgraduate School (Monterey, CA) out of Marina Municipal Airport in Marina, CA – see Photo.

The Twin Otter aircraft operated out of the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) during the Plankton, Aerosol, Cloud, ocean Ecosystem–Postlaunch Airborne eXperiment (PACE–PAX) campaign. The image shows the Twin Otter aircraft missing the approach at Marina Airport to check instrument performance on the aircraft against identical instrumentation on an airport control tower. Photo credit: NASA NASA’s ER-2 aircraft flies at an altitude of approximately 20 km, well above the troposphere. PACE–PAX researchers used the unique high-altitude vantage point to make observations of the atmosphere, ocean, and land surface in a similar manner to that of PACE. In so doing, they can verify the accuracy of data gathered by the satellite in orbit. Meanwhile, the Twin Otter flew at a much lower altitude in the atmosphere (~3 km). The instrumentation onboard the Twin Otter was used to sample and measure cloud droplet size, aerosol size, and the amount of light scattered or absorbed by the particles. These aircraft observations are the same atmospheric properties that PACE observes from its broader vantage point in polar orbit. In addition to the PACE and aircraft observations, the R/V Shearwater operated 15 day trips out of Santa Barbara, CA, gathering additional surface-based observations along with other vessels and floats.
Field campaigns, such as PACE–PAX, are designed to collect measurements at different scales and conditions for comparison to satellite observations. When it comes to doing this successfully, timing is everything. PACE–PAX observations were carefully coordinated so that the two aircraft were in flight and taking observations at the same time, so observations were being obtained at the surface (e.g., on the ship) as well as the satellite passing overhead. This takes a tremendous amount of effort on the part of the organizers.
BlueFlux
BlueFlux was set up to study the wetland ecosystems of South Florida. Wetland ecosystems represent the ever-changing line between land and sea, and are exceptionally vulnerable to climate disturbances, such as sea level rise and tropical cyclones. As these threats intensify, wetland ecology – and its role as a critical sink of CO2 – faces an uncertain future.
BlueFlux observations will contribute to the development of a new, remote-sensing data product called “Daily Flux Predictions for South Florida,” which will help research teams led by Ben Poulter [GSFC] explain and quantify the changing relationship between wetlands and atmospheric greenhouse gas concentrations (GHG). The goal is to refine global GHG budget analyses and provide regional stakeholders with information to evaluate how Florida’s wetlands are responding to natural and anthropogenic pressures in real time.
The “Daily Flux Predictions for South Florida” product will use retrievals of surface spectral reflectance captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA’s Aqua and Terra satellites to estimate the rate at which various gasses are exchanged between Earth’s surface and the atmosphere. Such flux measurements in coastal wetlands are historically limited on account of the relative inaccessibility of these ecosystems. To contribute to a more robust understanding of how Florida’s coastal ecology fits into the carbon cycle, BlueFlux conducted a series of airborne fieldwork deployments out of the Miami Homestead Air Reserve Base and the Miami Executive Airport in Miami-Dade County, which are adjacent to the eastern border of the Everglades National Park. The full study region – broadly referred to as South Florida – is narrowly defined by the wetland ecosystems that extend from Lake Okeechobee and its Northern estuaries to the saltwater marshland and mangrove forests along the state’s southernmost shore.
Flux measurements were made along each flight track using a payload known as the CARbon Airborne Flux Experiment (CARAFE) flying at between about 90 m and 3000 m. The researchers configured airborne observations, along with additional ground-based flux measurements, to match the spatial and temporal resolution of spectra collected by MODIS sensors, which produce surface reflectance retrievals at a 500 m daily resolution. Mirroring the scale of MODIS observations was necessary to both train the flux product’s underlying machine-learning algorithms and validate the accuracy of predictions made using satellite data alone. Data collected during BlueFlux fieldwork campaigns is available to the general public through NASA’s Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC). The “Daily Flux Predictions for South Florida” data product will also be accessible through NASA’s ORNL DAAC by early 2025.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Note: The following article is part of a series highlighting propulsion testing at NASA’s Stennis Space Center. To access the entire series, please visit: https://www.nasa.gov/feature/propulsion-powering-space-dreams/.
Contrary to the popular saying, work conducted by the propulsion test team at NASA’s Stennis Space Center is rocket science – and requires all the talent, knowledge, and expertise the term implies.
Rocket science at NASA Stennis, located near Bay St. Louis, Mississippi, has helped safely power American space dreams for almost 60 years ago. The accumulated knowledge and skills of the site’s test team continue to benefit NASA and commercial aerospace companies, thanks to new generations of skilled engineers and operators.
“The innovative, can-do attitude started with the founding of the south Mississippi site more than six decades ago,” said NASA Stennis Director John Bailey. “The knowledge, skills, and insight of a versatile team continue supporting NASA’s mission and goals of commercial aerospace companies by routinely conducting successful propulsion testing at NASA Stennis.”
Test team personnel perform facility data review following completion of a liquid oxygen cold-flow activation activity on the E-1 Test Stand at NASA’s Stennis Space Center on March 23, 2016. Activation of the test cell was in preparation for testing L3Harris’ (then known as Aerojet Rocketdyne) AR1 rocket engine pre-burner and main injector. The versatile four-stand E Test Complex includes 12 active test cell positions capable of various component, engine, and stage test activities for NASA and commercial projects. NASA/Stennis Operators at NASA’s High Pressure Gas Facility conduct a critical stress test Oct. 18-19, 2018, to demonstrate the facility’s readiness to support testing of the core stage of NASA’s powerful SLS (Space Launch System) rocket. The High Pressure Gas Facility was critical in producing and delivering gases needed for SLS core stage testing ahead of the successful launch of Artemis I. NASA/Stennis Test control center crews at NASA’s Stennis Space Center’s simulate full operations of core stage testing Dec. 13, 2019, for NASA’s powerful SLS (Space Launch System) rocket on the Thad Cochran Test Stand (B-2). NASA Stennis conducted SLS core stage testing in 2020-21 ahead of the successful Artemis I mission. NASA/Stennis A sitewide stress test at NASA’s Stennis Space Center on Dec. 13, 2019, simulates full operations needed during SLS (Space Launch System) core stage testing. The 24-hour exercise involved crews across NASA Stennis, including at the High Pressure Water Facility that provided needed generator power and water flow to the Thad Cochran Test Stand (B-2) during testing.NASA/Stennis The NASA Stennis team exhibits a depth and breadth of experience and expertise likely unsurpassed anywhere in the world.
The depth is built on decades of propulsion test experience. Veteran team members of today learned from those working during the Apollo era, who overcame various engineering, technical, communications, and mechanical difficulties in testing the Saturn V rocket stages that powered humans to the Moon. During 43 stage firings, the team accumulated an estimated 2,475 years of rocket engine test expertise.
Members of the Apollo test team then joined with new engineers and operators to test main engines that powered 30 years of space shuttle missions. From 1975 to 2009, the team supported main engine development, certification, acceptance, and anomaly testing with over 2,300 hot fires and more than 820,000 seconds of accumulated hot-fire time.
“NASA Stennis is unique because of the proven test operations expertise passed from generation to generation,” said Joe Schuyler, director of the NASA Stennis Engineering and Test Directorate. “It is expertise you can trust to deliver what is needed.”
A member of the Fred Haise Test Stand (formerly the A-1 Test Stand) operations team examines the progress of a cold-shock test on May 1, 2014. The test marked a milestone in preparing the stand to test RS-25 rocket engines that will help power NASA’s SLS (Space Launch System) rocket.NASA/Stennis In addition to depth, the site team also has a breadth of experience that gives it unparalleled versatility and adaptability.
Part of that comes from the nature of the center itself. NASA Stennis is the second largest NASA center in terms of geography, but the civil servant workforce is small. As a result, test team members work on a range of propulsion projects, from testing components on smaller E Test Complex cells to firing large engines and even rocket stages on the heritage Apollo-era stands.
“Our management have put us in a position to be successful,” said NASA engineer Josh Greiner. “They have helped move us onto the test stands and given us a huge share of the responsibility of leading projects early in our career, which provides us the confidence and opportunity to conduct tests.”
In addition, center leaders made a deliberate decision more than a decade ago to return test stand operations to the NASA team. Prior to that time, stand operations were in the hands of contractors under NASA supervision. The shift allowed the civil servant test team to fine-tune its skill set even as it continued to work closely with contractor partners to support both government and commercial aerospace propulsion projects.
An image from October 2022 shows NASA engineers preparing for the next RS-25 engine test series at NASA’s Stennis Space Center by monitoring the reload of propellant tanks to the Fred Haise Test Stand (formerly the A-1 Test Stand). RS-25 engines are powered by a mix of liquid hydrogen and liquid oxygen.NASA/Stennis An image from October 2022 shows test team personnel ensuring pressures and flow paths are set properly for liquid oxygen to be transferred to the Fred Haise Test Stand (formerly the A-1 Test Stand), pictured in the background.NASA/Stennis An image from August 2023 shows test team personnel inspecting a pump during an initial chill down activity at the E-3 Test Complex. The versatile four-stand E Test Complex includes 12 active test cell positions capable of various component, engine, and stage test activities for NASA and commercial programs and projects. NASA/Stennis An image from September 2023 shows test team personnel preparing for future SLS (Space Launch System) exploration upper stage testing that will take place on the B-2 side of the Thad Cochran Test Stand. NASA’s new upper stage is being built as a more powerful SLS second stage to send the Orion spacecraft and heavier payloads to deep space. It will fly on the Artemis missions following a series of Green Run tests of its integrated systems at NASA Stennis. The test series will culminate with a hot fire of the four RL10 engines that will power the upper stage.NASA/Stennis An image from September 2023 shows test team personnel preparing for future SLS (Space Launch System) exploration upper stage testing by conducting a liquid hydrogen flow procedure. NASA’s new upper stage is being built as a more powerful SLS second stage to send the Orion spacecraft and heavier payloads to deep space. The upper stage will undergo a series of Green Run tests of its integrated systems on the B-2 side of the Thad Cochran Test Stand at NASA Stennis.NASA/Stennis The evolution and performance of the NASA Stennis team was illustrated in stark fashion in June/July 2018 when a blended team of NASA, Defense Advanced Research Projects Agency, Aerojet Rocketdyne, Boeing, and Syncom Space Services engineers and operators test fired an AR-22 rocket engine 10 times in a 240-hour period.
The campaign marked the first time a large liquid oxygen/liquid hydrogen engine had been tested so often in such a short period of time. The test team overcame a variety of challenges, including a pair of lightning strikes that threatened to derail the entire effort. Following completion of the historic series, a NASA engineer who helped lead the campaign recounted one industry observer who repeatedly characterized the site’s test team as nothing less than a national asset.
The experienced site workforce now tests RS-25 engines and propulsion systems for NASA’s Artemis campaign, including those that will help power Artemis missions to the Moon for scientific discovery and economic benefits. The NASA Stennis team also supports a range of commercial aerospace propulsion test activities, facilitating continued growth in capabilities. For instance, the team now has experience working with oxygen, hydrogen, methane, and kerosene propellants.
“The NASA and contractor workforce at NASA Stennis is second to none when it comes to propulsion testing,” Schuyler said. “Many of the current employees have been involved in rocket engine testing for over 30 years, and newer workers are being trained under these seasoned professionals.”

MuSat2 at Vandenberg Air Force Base, prior to launch. MuSat2 leverages a dual-frequency science antenna developed with support from NASA to measure phenomena such as ocean wind speed. Muon Space A science antenna developed with support from NASA’s Earth Science Technology Office (ESTO) is now in low-Earth orbit aboard MuSat2, a commercial remote-sensing satellite flown by the aerospace company Muon Space. The dual-frequency science antenna was originally developed as part of the Next Generation GNSS Bistatic Radar Instrument (NGRx). Aboard MuSat2, it will help measure ocean surface wind speed—an essential data point for scientists trying to forecast how severe a burgeoning hurricane will become.
“We’re very interested in adopting this technology and pushing it forward, both from a technology perspective and a product perspective,” said Jonathan Dyer, CEO of Muon.
Using this antenna, MuSat2 will gather signals transmitted by navigation satellites as they scatter off Earth’s surface and back into space. By recording how those scattered navigation signals change as they interact with Earth’s surface, MuSat2 will provide meteorologists with data points they can use to study severe weather.
“We use the standard GPS signals you know—the navigation signals that work for your car and your cell phone,” explained Chris Ruf, director of the University of Michigan Space Institute and principal investigator for NGRx.
Ruf designed the entire NGRx system to be an updated version of the sensors on NASA’s Cyclone Global Navigation Satellite System (CYGNSS), another technology he developed with support from ESTO. Since 2016, data from CYGNSS has been a critical resource for people dedicated to forecasting hurricanes.
The science antenna aboard MuSat2 enables two key improvements to the original CYGNSS design. First, the antenna allows MuSat2 to gather measurements from satellites outside the U.S.-based GPS system, such as the European Space Agency’s Galileo satellites. This capability enables MuSat2 to collect more data as it orbits Earth, improving its assessments of conditions on the planet’s surface.
Second, whereas CYGNSS only collected cross-polar radar signals, the updated science antenna also collects co-polar radar signals. This additional information could provide improved information about soil moisture, sea ice, and vegetation. “There’s a whole lot of science value in looking at both polarization components scattering from the Earth’s surface. You can separate apart the effects of vegetation from the effects of surface, itself,” explained Ruf.
Hurricane Ida, as seen from the International Space Station. NASA-developed technology onboard MuSat2 will help supply the U.S. Air Force with critical data for producing reliable weather forecasts. NASA For Muon Space, this technology infusion has been helpful to the company’s business and science missions. Dallas Masters, Vice President of Muon’s Signals of Opportunity Program, explains that NASA’s investments in NGRx technology made it much easier to produce a viable commercial remote sensing satellite. According to Masters, “NGRx-derived technology allowed us to start planning a flight mission early in our company’s existence, based around a payload we knew had flight heritage.”
Dyer agrees. “The fact that ESTO proves out these measurement approaches – the technology and the instrument, the science that you can actually derive, the products from that instrument – is a huge enabler for companies like ours, because we can adopt it knowing that much of the physics risk has been retired,” he said.
Ultimately, this advanced antenna technology for measuring ocean surface wind speed will make it easier for researchers to turn raw data into actionable science products and to develop more accurate forecasts.
“Information is absolutely precious. When it comes to forecast models and trying to understand what’s about to happen, you have to have as good an idea as you can of what’s already happening in the real world,” said oceanographer Lew Gramer, an Associate Scientist with the Cooperative Institute For Marine And Atmospheric Studies and NOAA’s Hurricane Research Division.
