Shortly after launch, Lunar Flashlight separated from the Falcon 9 to begin an approximately three-month journey that will carry it into a fuel-conserving orbital trajectory 42,000 miles beyond the moon. Gravity from the moon, Earth, and Sun will ultimately bring it into a path that will come within nine miles of the lunar surface.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EOnce in its science orbit around the moon, Lunar Flashlight will shine four lasers into perpetually-dark craters near the lunar South Pole. Each laser operates at a slightly different frequency, and the reflected light acts like a spectral fingerprint that identifies the material that it illuminated. If ice is there, the near-infrared light from the lasers will be absorbed by the water. If the light reflects back to the Lunar Flashlight, that will indicate the absence of ice. Data from the spacecraft will be radioed to NASA\u0026rsquo;s Deep Space Network and received by student controllers on the Georgia Tech campus, who will then share it with the Lunar Flashlight Science Team.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ESurface water ice may be a treasure trove of water from different sources such as volcanic outgassing and meteorite impact, so knowing where it resides will help point future assets to examine it at the surface. If sufficient amounts exist, the precious liquid may be used to help meet the drinking water needs of future lunar colonies.\u0026nbsp;Water molecules from potential ice reservoirs in the South Pole craters could also be split to provide a source of oxygen for breathing and hydrogen for rocket fuel.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EBig Capabilities in a Small Spacecraft\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EDespite its small size, Lunar Flashlight \u0026ndash; which was designed by \u003Ca href=\u0022https:\/\/www.nasa.gov\/feature\/jpl\/nasa-s-lunar-flashlight-ready-to-search-for-the-moon-s-water-ice\u0022\u003ENASA\u0026rsquo;s Jet Propulsion Laboratory\u003C\/a\u003E \u0026ndash; has big capabilities.
