What is Public Access

The Public Access initiative is part of the agency’s framework for increasing public access to scientific publications and digital scientific data.

OSTP Memorandum

The Public Access initiative follows the release of White House Office of Science and Technology Policy’s (OSTP) memorandum “Increasing Access to the Results of Federally Funded Research,” launch to ensure federally funded research is available to the public within one year of publication.

Public Access to Results of NASA-Funded Research

NASA answered the OSTP mandate by creating:

• An agency plan entitled “NASA Plan for Increasing Access to the Results of Scientific Research” launch
• Associated policy, NPD 2230.1, Research Data and Publication Access. launch

Together, they outline a framework for activities to increase public access to scientific publications and digital scientific data resulting from NASA-funded research.

Publication Management

All NASA-funded researchers (both civil servant and non-civil servant) are required launch to ensure that copies of publications and associated data are made available in NASA’s designated public access repository, PubSpace launch . This excludes patents, publications that contain material governed by personal privacy, export control, proprietary restrictions, or national security law or regulations.

PubSpace launch is NASA’s designated public access repository. It is a collection of NASA-funded scholarly publications within the STI Repository launch , aiming to increase access to federally funded research in accordance with NASA Public Access Policy launch . The collection enables free public access to NASA’s peer-reviewed scholarly publications, including accepted manuscripts and publisher version of record, after the designated publisher embargo period.  

NASA has entered into a partnership agreement with the Clearinghouse for the Open Research of the United States (CHORUS) publishing group, which serves as a component to the PubSpace Collection. NASA researchers who publish in a CHORUS member’s journal can now more easily satisfy the  Agency’s requirements for public access launch .

Guidance for how to locate publications in PubSpace and how to submit publications that are not available from CHORUS can be found on the Submit to PubSpace page launch .

Journal Article Versions Explained

• Preprint – The journal article version that is submitted to the journal publisher to request acceptance and publication.
• Accepted Manuscript – The version of the journal article that has been accepted for publication by a journal publisher and includes changes requested by the publisher and made by the author during the peer-review process. It typically includes the same content as the published article in the journal but frequently (not always) does not include the publisher’s form or format. This is the version collected for PubSpace.
• Reprint – The version that is published in the journal by the publisher. It will typically have the date of publication and volume number. Some Federal agencies and publishers also call these the Version of Record manuscript.

STI Compliance and Distribution Services Involvement

NASA STI Compliance and Distribution Services manages several areas of public access to research as part of our mission to support the advancement of knowledge and contributing to U.S. competitiveness in space science and aerospace research and development.

STI Compliance and Distribution Services supports public access to research by:

• Staffing the NASA Public Access Help Desk
• Providing support to NASA-funded researchers
• Maintaining a comprehensive collection of NASA-authored and NASA-funded peer-reviewed publications in the NASA STI Repository launch , including the PubSpace Collection

Efficient Estimation of the Number of Clusters for High-Dimensional Data

S. Kasapis, G. Zhang, J. Smereka, N. Vlahopoulos Published online December 6, 2023

The exponential growth of digital image data has given rise to the need of efficient content management and retrieval tools. Despite its popularity, the VRC method comes with two very important shortcomings: it only yields good results when the data dimensionality is low and it does not scale well for a high number of clusters, making it very difficult to use in computer vision applications. We propose an extension to the VRC method that works for increased cluster number and high-dimensionality data sets and therefore is fit for image data sets. Efficient Estimation of the Number of Clusters for High-Dimensional Data The Journal of Defense Modeling and Simulation: Applications, Methodology, Technology, December 2023.

Grid Topology for Time-Accurate Deployment Simulation of 2D Parachutes by using Navier-Stokes Equations

G. Guruswamy Published online October 31, 2023

A new grid topology approach suitable for body-fitted structured grids is presented to time-accurately simulate deployment of parachutes. The goal is to provide an alternate to the current use of Cartesian and unstructured grids that are less desired from turbulence modeling aspects compared to the body-fitted structured grids. Time-accuracy essential for the deployment is maintained, unlike in the quasi-steady loose coupling methods used elsewhere with the Cartesian/unstructured grids. The current paper establishes the new approach for a 2D case that can lead to 3D cases.

Spectro-Polarimetric Properties of Sunquake Sources in X1.5 Flare and Evidence for Electron and Proton Beam Impacts

A. Kosovichev, V. Sadykov, J. Stefan Published online September 13, 2023

The first significant sunquake event of Solar Cycle 25 was observed during the X1.5 flare of May 10, 2022, by the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory. We perform a detailed spectro-polarimetric analysis of the sunquake photospheric sources, using the Stokes profiles of the FeI 6173A line, reconstructed from the HMI linear and circular polarized filtergrams.

Automatic Runtime Scheduling Via Directed Acyclic Graphs for CFD Applications

H. Torres, S. Murman Published online June 8, 2023

The order of execution of computational kernels for Single-Program, Multiple-Data (SPMD) programs is usually determined at compile time. These static predetermined schedules can lead to performance issues at runtime, and are difficult to implement for inhomogeneous situations, such as variable-order or multi-physics applications. It is especially challenging to generate performant schedules when it is unknown whether specific kernels require execution, as a function of user inputs, or the kernel execution time changes dependent on the hardware. This paper presents a solution to this problem by dynamically scheduling computational kernels at runtime using directed acyclic graphs to track the data dependencies between kernels.

Computational Study of Low-Speed Boundary-Layer Laminar-Turbulent over a 30-Degree Swept Plate in a Channel

M. Denison, J. Smith, J. Eppink Published online June 8, 2023

Reliable boundary-layer laminar-turbulent transition predictions are critical for the design of aircraft that use natural or controlled laminar flow to achieve low drag and better fuel efficiency. During cruise flight through low turbulence, the three-dimensional boundary layer over swept surfaces can transition prematurely due to stationary crossflow instabilities induced by surface roughness. Parabolized stability equations analyses have been successfully used to explain the different phases of the transition process under well controlled perturbations such as steps or discrete roughness elements.

Multi-Fidelity Computational Analysis of a Quiet Single-Main Rotor Helicopter for Air Taxi Operations

P. Ventura Diaz, D. Perez, S. Yoon Published online June 8, 2023

A multi-fidelity computational study has been conducted on NASA's quiet single-main rotor helicopter concept for urban air mobility using computational fluid dynamics and rotorcraft comprehensive analysis tools. Two approaches have been followed in order to simulate the rotor flows: (1) a rotor disk model, which models the rotors as source terms, and (2) a high-fidelity approach using high-order accurate schemes and dual-time stepping, which simulates the rotor with its individual rotating blade grids.

Nonzero Phase Shifts of Acoustic Waves in the Lower Solar Atmosphere Measured from Realistic Simulations and Their Role in Local Helioseismology

M. Waidele, J. Zhao, I. Kitiashvili Published June 2, 2023

Previous studies analyzing the evanescent nature of acoustic waves in the lower solar atmosphere, up to 300 km above the photosphere, have shown an unexpected phase shift of an order of 1 s between different heights. Those studies investigated the spectral line Fe Ιλ6173.3, commonly used for helioseismic measurements. Such phase shifts can contribute to a misinterpretation of the measured travel times in local helioseismology, complicating inferences of, e.g., the deep meridional flow. In this study, we carry out phase shift computations using a simulated, fully radiative, and convective atmosphere from which the Fe Ιλ6173.3 line is synthesized.

Statistical Study of the Correlation between Solar Energetic Particles and Properties of Active Regions

R. Marroquin, V. Sadykov, A. Kosovichev, I. Kitiashvili, et al. Published online March 10, 2023

The flux of energetic particles originating from the Sun fluctuates during the solar cycles. It depends on the number and properties of Active Regions (ARs) present in a single day and associated solar activities, such as solar flares and coronal mass ejections (CMEs). Observational records of the Space Weather Prediction Center (SWPC NOAA) enable the creation of time-indexed databases containing information about ARs and particle flux enhancements, most widely known as Solar Energetic Particle events (SEPs). In this work, we utilize the data available for Solar Cycles 21-24, and the initial phase of Cycle 25 to perform a statistical analysis of the correlation between SEPs and properties of ARs inferred from the McIntosh and Hale classifications.

A. Ali, V. Sadykov, A. Kosovichev, I. Kitiashvili, et al. Published online March 9, 2023

Solar Energetic Particle (SEP) events and their major subclass, Solar Proton Events (SPEs), can result in unfavorable consequences to numerous aspects of life and technology, making them one of the most prevalent and harmful effects of solar activity. Garnering knowledge leading up to such events by studying proton and soft X-ray (SXR) flux data to alleviate the burdens they cause is therefore critical for their forecasting.

Modeling Stellar Jitter for the Detection of Earth-Mass Exoplanets via Precision Radial Velocity Measurements

S. Granovsky, I. Kitiashivili, A. Wray Published online January 20, 2023

The detection of Earth-size exoplanets is a technological and data analysis challenge. Future progress in Earth-mass exoplanet detection is expected from the development of extreme precision radial velocity measurements. Increasing radial velocity precision requires developing a new physics-based data analysis methodology to discriminate planetary signals from host-star-related effects, taking stellar variability and instrumental uncertainties into account. In this work, we investigate and quantify stellar disturbances of the planet-hosting solar-type star HD121504 (G2V spectral type) from 3D radiative modeling obtained with the StellarBox code.

3D Realistic Modeling of Solar-Type Stars to Characterize the Stellar Jitter

I. Kitiashivili, S. Granovsky, A. Wray Published online January 20, 2023

Detection of Earth-mass planets with the radial velocity method requires a precision of about 10cm/s to identify a signal caused by such a planet. At the same time, noise originating in the photospheric and subphotospheric layers of the parent star is of the order of meters per second. Understanding the physical nature of the photospheric noise (so-called stellar jitter) and characterizing it are critical for developing techniques to filter out these unwanted signals. We take advantage of current computational and technological capabilities to create 3D realistic models of stellar subsurface convection and atmospheres to characterize the photospheric jitter. 3D Realistic Modeling of Solar-Type Stars to Characterize the Stellar Jitter 241st Meeting of the American Astronomical Society, Seattle, WA, January 8-12, 2023.

Advances in Space Launch System Booster Separation CFD

J. Meeroff, D. Dalle, S. Rogers, A. Burkhead, D. Schauerhamer, J. Diaz Published online January 19, 2023

The Space Launch System (SLS) employs two Space Shuttle derived Solid Rocket Boosters (SRBs) which separate from the SLS core while still experiencing appreciable aerodynamic loads. Creating an aerodynamic database for this phase of flight can be challenging due to the large number of independent variables needed to fully constrain the problem and the complex flow induced by exhaust plumes of the booster separation motors (BSMs) and core main engines impinging on other parts of the vehicle. This paper details recent efforts in generating aerodynamic databases for SLS during the booster separation event using viscous Computational Fluid Dynamic (CFD) simulations obtained using NASA's FUN3D solver.

Launch Vehicle Ascent CFD for the Space Launch System

D. Dalle, S. Rogers, J. Meeroff, A. Burkhead, D. Schauerhamer, J. Diaz Published online January 19, 2023

This paper will discuss the use of Computational Fluid Dynamics (CFD) for the Space Launch System (SLS) Program to model the ascent phase of flight. The ascent phase begins shortly after the vehicle clears the launch tower and extends to the first staging event. To model SLS’s ascent, over one thousand numerical solutions of the Navier-Stokes equations are solved, and this analysis has been repeated for five different SLS configurations. To manage this demanding ascent CFD task, the SLS program has developed the Computational Aerosciences Productivity & Execution (CAPE) software, which is introduced in the paper.
