In celestial mechanics, the Lagrange points, also called the Lagrangian points or libration points, are points of equilibrium for small-mass objects under the gravitational influence of two massive or

…the sphere. The telescope also measured the CMB's E-mode polarization, and foreground polarization. Its service life was 27 months; 3 to reach the L2 position, and 2 years of observation. The MAP mission was proposed to NASA in 1995, selected for definition study in 1996, and approved for development…
