The NASA-LMT was a 3 m (9.8 ft) apertureliquid-mirror telescope located in NODO's main dome. It consisted of a 3 m diameter parabolic dish that held 4 U.S. gallons (15 L) of a highly reflective liquid metal, mercury, spinning at a rate of 10 rpm, with sensors mounted above on a fixed structure. Due to the primary mirror's material, the NASA-LMT was configured as a zenith telescope. Using 20 narrowband filters, it cataloged space debris in Earth's orbit.[2] The telescope was initially completed in 1994 at NASA's Johnson Space Center, and moved to Cloudcroft the following year, where it operated routinely until June 2002.[3] The LMT was also used for the UBC-NASA Multi-Narrowband survey, which examined galaxies at moderate redshifts.[4] When it was retired, some of the components were used in the 6 m (20 ft) Large Zenith Telescope in British Columbia.
