LRO and LCROSS are two space missions sent by NASA to Earth's Moon. LRO and LCROSS were launched together on an Atlas rocket from Cape Canaveral in Florida on June 18, 2009.

The Lunar Reconnaissance Orbiter (LRO) is a satellite that is now orbiting the Moon. LRO is mapping the Moon at very high resolution from a low orbit just 50 km (30 miles) above the lunar surface. These detailed maps will be used for planning of other upcoming robotic and human missions to the Moon. LRO is also searching for signs of water ice near the lunar poles and is studying radiation levels around the Moon, which will be important to know when astronauts return in the coming years.

The Lunar CRater Observation and Sensing Satellite (LCROSS) is designed to intentionally crash into the Moon on October 9, 2009. The goal of LCROSS is to detect signs of water ice in craters near the Moon's South Pole, if any is there. The Centaur upper stage of the rocket that launched LRO and LCROSS will crash into Cabeus crater, producing a huge plume of ejecta material. LCROSS will search for signs of water molecules within the ejecta cloud. Soon after the crash of the Centaur rocket, the LCROSS spacecraft will also smash into the Moon. Telescopes on Earth will observe both crashes.

LRO stands for "Lunar Reconnaissance Orbiter". LRO is in orbit around the Moon. It is taking very detailed pictures of the Moon's surface. These pictures will be used to make a better new map of the Moon. That map will help scientists plan other Moon missions that are coming up in the next few years. LRO is also searching for signs of water ice near the Moon's North and South Poles. LRO is also studying radiation near the Moon. That will be important to know about when astronauts go back to the Moon.

LCROSS stands for Lunar CRater Observation and Sensing Satellite. LCROSS will crash into the Moon on purpose! It will hit the Moon near the South Pole on October 9, 2009. LCROSS is trying to detect signs of water ice in craters near the Moon's South Pole, if any is there. The Centaur upper stage of the rocket that launched LRO and LCROSS will crash into a crater near the South Pole. Scientists think there might be water ice in that crater. The crash will create a large plume of material when the Centaur explodes upon impact. LCROSS will use instruments to search for signs of water molecules within the plume. The LCROSS spacecraft will also smash into the Moon soon after the Centaur rocket. Telescopes on Earth will watch both crashes.
