In one system, the U axis is directed toward the Galactic Center (l = 0°), and it is a right-handed system (positive towards the east and towards the north galactic pole); in the other, the U axis is directed toward the galactic anticenter (l = 180°), and it is a left-handed system (positive towards the east and towards the north galactic ...
After a brief test program in Waco to partially expand the flight envelope and perform post-maintenance checks, the aircraft was moved on May 31, 2007, to NASA's Armstrong Flight Research Center at Edwards Air Force Base. The first phase of loads and flight testing was used to check the aircraft characteristics with the external telescope ...
Test; Inspection; Demonstration; Similarity (although Similarity is a form of Analysis, in most space applications, it is recommended to highlight it as its own category) Being qualified means demonstrating with margin that the design, and the implementation of the design, meets the intended preset requirements.
The National Aeronautics and Space Administration (NASA / ˈ n æ s ə /) is an independent agency of the US federal government responsible for the United States' civil space program, aeronautics research and space research.
As of 2024, nearly 80 different government space agencies are in existence, including more than 70 national space agencies and several international agencies. Initial competencies demonstrated include the funding and nomination of candidates to serve as astronauts, cosmonauts, or taikonauts with the countries/organizations executing human spaceflight solutions.

The original Sloan Extension for Galactic Understanding and Exploration (SEGUE-1) obtained spectra of nearly 240,000 stars of a range of spectral types. Building on this success, SEGUE-2 spectroscopically observed around 120,000 stars, focusing on the in situ stellar halo of the Milky Way, from distances of 10 to 60 kpc.
It is part of NASA's Explorers program, which designs low-cost spacecraft to study heliophysics and astrophysics. The mission will study exotic astronomical objects and permit mapping of the magnetic fields of black holes , neutron stars , pulsars , supernova remnants , magnetars , quasars , and active galactic nuclei .
