Years after the demise of the Soviet lunar program, shrouds, tanks and other pieces of the giant N-1 rockets remain scattered around Baikonur, serving as storage, gazebos and playgrounds. Copyright © 2000 by Anatoly Zak

The N1-L3 complex was developed for the ill-fated Soviet effort to land a man on the Moon.

HARDWARE

At the beginning of the 1960s, the OKB-1 design bureau led by Sergei Korolev started work on a super-heavy rocket booster, later designated N1. Originally proposed as a multipurpose vehicle for a variety of military and scientific tasks, the N1 evolved into a project with a single mission -- to beat America to the Moon. However, the N-1's catastrophic failures during four test launches in 1969-1972 doomed the Soviet effort to land a man on the Moon and left the ill-fated rocket under a veil of secrecy for decades.

N1 test launches:

Feb. 21, 1969: The first test launch of the N-1 rocket (Vehicle No. 3L) failed 68.7 seconds after liftoff.

July 3, 1969: The second test launch of the N-1 rocket (Vehicle No. 5L) failed immediately after liftoff.

June 27, 1971: The third launch of the N1 rocket (Vehicle No. 6L) failed at 50.1 seconds after liftoff from the left pad of the Site 110 in Baikonur.

Nov. 23, 1972: The fourth launch of the N1 rocket (Vehicle No. 7L) failed about 107 seconds after liftoff.
