What data do we get when we observe stars?
The dataset includes the date, the velocity we measured, the error on that velocity, and measurements of the star’s activity during that observation,” Burt says. “Nowadays, with access to public analysis software like Systemic, it’s easy to load the data in and start playing with it.”
How was the star map created?
The star map in celestial coordinates, at five different resolutions. This set of star maps was created by plotting the position, brightness, and color of 1.7 billion stars from the Hipparcos-2, Tycho-2, and Gaia Data Release 2 star catalogs, with help from the Yale Bright Star Catalog, UCAC3, and the XHIP Hipparcos cross-reference.

nasa database patents
Is there a searchable database of expired NASA patents?
In addition to the release of these technologies, a searchable database now is available that catalogs thousands of expired NASA patents already in the public domain.
What kind of Patents does NASA have?
NASA maintains a portfolio of patents with commercial potential and makes them available to the public through our patent licensing program
How many NASA patents are in public domain?
NASA Makes Dozens of Patents Available in Public Domain to Benefit U.S. Industry NASA has released 56 formerly-patented agency technologies into the public domain, making its government-developed technologies freely available for unrestricted commercial use.
What is NASA’s approach to intellectual property and data?
The intellectual property and data clauses provided in this manual reflect NASA’s basic approach that has evolved over the years for commonly encountered circumstances. However, since the Space Act permits flexibility in these matters, it may be desirable to modify the clauses to fit particular circumstances, within the following parameters.
nasa airfoil database
How are the airfoils listed in the airfoil data site?
The UIUC Airfoil Data Site gives some background on the database. The airfoils are listed alphabetically by the airfoil filename (which is usually close to the airfoil name). Answers to frequently asked questions are posted here Airfoils FAQ and for the most recent changes see the update history.
What’s new in NACA airfoil data?
Summary of Airfoil Data The historical development of NACA airfoils is briefly reviewed. New data are presented that permit the rapid calculation of the approximate pressure distributions for the older NACA four-digit and five-digit airfoils by the same methods used for the NACA 6-series airfoils.
