WMAP satellite Trivia Questions

WMAP was a NASA mission developed by the Goddard Space Flight Center and Princeton University, with contractor support.

WMAP orbited the Sun-Earth L2 Lagrange point, about 1.5 million km from Earth—not around the Moon.

WMAP actually used passive radiators to cool its instruments, but no cryogens—though this statement is true! Wait, checking: WMAP did not use cryogens; it was passively cooled. So this is TRUE, not false. Let me correct.

WMAP's final analysis in 2012 gave the age of the universe as 13.772 billion years, with just 0.3% uncertainty.

MAP was renamed the Wilkinson Microwave Anisotropy Probe in 2003 to honor David T. Wilkinson, a key team member who died in 2002.

Gravitational waves from the Big Bang were not detected until BICEP2 (2014) and later Planck—WMAP lacked the sensitivity.

WMAP detected tiny variations in the CMB of about 0.0002 Kelvin, revealing seeds of galaxy formation.

WMAP's measurements of the cosmic microwave background showed the universe's geometry is nearly flat, with a density parameter very close to 1.
