[单项选择]

Like the space telescope he championed, astronomer Lyman Spitzer faced some perilous moments in his career. Most notably, on a July day in 1945, he happened to be in the Empire State building when a B- 25 Mitchell bomber lost its way in fog and crashed into the skyscraper 14 floors above him. Seeing debris falling past the window, his curiosity got the better of him, as Robert Zimmerman recounts in his Hubble history, The Universe in a Mirror. Spitzer tried to poke his head out the window to see what was going on, but others quickly convinced him it was too dangerous.
Spitzer was not the first astronomer to dream of sending a telescope above the distorting effects of the atmosphere, but it was his tireless advocacy, in part, that led NASA to launch the Hubble Space Telescope in 1990. Initially jubilant, astronomers were soon horrified to discover that Hubble’s 2.4-metre main mirror had been ground to the wrong shape. Although it was only off by 2.2 micrometers, this
A. to commemorate his perilous and dangerous experience in his early days
B. to show how the astronomer made and realized his dream
C. to present an analogy to the hard experiences of the future space telescope
D. to reveal how his dream of sending a telescope into space has materialized
