After that, Hiten was put into a looping orbit which passed through the L4 and L5 Lagrange points to look for trapped dust particles: the then-tentatively observed Kordylewski clouds. The only scientific instrument on Hiten was the Munich Dust Counter (MDC), and no increase over background levels was found. On February 15, 1993, Hiten was placed into a permanent lunar orbit, where it remained until it was deliberately crashed[why?] into the lunar surface on April 10, 1993 at 34°18′S 55°36′E﻿ / ﻿34.3°S 55.6°E﻿ / -34.3; 55.6, between the craters Stevinus and Furnerius.[2][10]
