  • DART impact might have reshaped Hera's target asteroid
    on February 26, 2024 at 4:00 pm

    ESA’s Hera spacecraft for planetary defence is being prepared for a journey to the distant asteroid moon Dimorphos orbiting around its parent body Didymos. One of the first features Hera will look for is the crater left on Dimorphos by its predecessor mission DART, which impacted the asteroid to deflect its orbit. Yet a new impact simulation study reported in Nature Astronomy today suggests no crater will be found. The DART impact is likely to have remodelled the entire body instead – a significant finding for both asteroid science and planetary defence.

  • Harvesting Data from the NASA STI Repository
    on March 25, 2021 at 11:46 pm

    Harvesting Data from the NASA STI Repository The STI Repository promotes the dissemination of NASA STI to the widest audience possible by allowing information to be harvested. In support of these objectives, the upgraded repository has an OpenAPI to provide greater access to publicly available data and further flexibility for dissemination of NASA research results. The OpenAPI is the recommended mechanism for access to NASA’s public collection of STI, and is available along with the following API documentation and guidance:

    For Developers NASA API’s launch makes NASA data, including imagery, eminently accessible to application developers. The NASA STI Repository OpenAPI is the recommended mechanism for access to NASA’s public collection of STI, and is available along with API documentation and guidance. What is STI? STI (scientific and technical information) is defined as a paper, abstract, journal article, presentation, etc. that contains and delivers the results (the analyses of the data, facts, and resulting conclusions) of basic and applied scientific, technical and related engineering research and development.

    The NASA STI Program The NASA Scientific and Technical Information (STI) Program is a critical component in the worldwide activity of scientific and technical aerospace research and development. The NASA STI Program acquires, processes, archives, announces, and disseminates NASA STI and acquires worldwide STI of critical importance to NASA and the Nation. Collected from U.S. and international sources, STI is organized according to content prior to being added to the NASA STI Repository (NTRS) launch .
