MAP starts its observations
Prof. Edward L. (Ned) Wright of UCLA Physics & Astronomy is the
data team leader on the
Microwave Anisotropy Probe
(MAP), which reached
its observing station at the second Lagrange point (L2) in the
Earth-Sun system on 1 Oct 2001 after a three month cruise following
launch on 30 June 2001.
MAP will measure the
temperature differences in the
cosmic microwave background (CMB) that reveal the structure of the
Universe at the time of recombination, a few hundred thousand years
after the Big Bang.
MAP will map the entire sky 4 times over the next 24 months, providing
a treasure trove of information about
