    The Astrophysics Research Knowledgebase (ARK) is a service provided by NASA's High Energy Astrophysics Science Archive Research Center (HEASARC) designed to create a user database of results related to the archival data hosted by the HEASARC. ARK provides a web interface to submit and search information stored in the database. ARK is also used for the HEASARC's Remote Proposal System, supporting a variety of missions.

    Registration is required to access the service. Users are given permissions to submit to and/or search specific tables in the database based on their needs. If a group of users wants to collaborate and share results via ARK, contact our <& /akbar/lib/contact_url.mas, text => "help desk" &>.
