October 6, 2006 - The Fire Within, Part II: Making Metamorphic and Sedimentary Rocks
Learn to identify different metamorphic and sedimentary rocks, explore how they form, and relate their formation to plate tectonics and the rock cycle. The day will close by examining evidence of these types of rocks on other planets. Participants will receive extensive presentation materials on CD, reference materials, and lesson plans for hands-on classroom activities. Part I strongly recommended. Fee: $75, Credits: 6 CPE hours Audience: 5th –8th grade Teachers

Living and Working on the Moon
Teachers can invite students to design systems that will support living and working on the Moon. The challenge will be to design a combination of facilities that support arriving precisely, living adaptively and working efficiently that will make exploration possible on the Moon and can protect both the explorers and the Moon from contamination. NASA has a growing list of reading materials that will help you get started by visiting Lunar Outpost Design Challenge. If you have any questions you can write to Quest-Challenge@mail.arc.nasa.gov.

NASA introduces LCROSS
Modified from: In Search of Water, NASA spacecraft to hit the Moon
NASA recently announced that a small spacecraft has been selected to travel to the moon to look for precious water ice at the lunar south pole. The name of the mission is LCROSS, short for Lunar CRater Observation and Sensing Satellite. LCROSS is a secondary payload: It will hitch a ride to the moon onboard the same rocket as the Lunar Reconnaissance Orbiter (LRO) satellite due to launch from the Kennedy Space Center in October 2008. LCROSS will hunt for water by hitting the moon — twice — throwing up plumes that may contain signs of H2O.
Lunar Reconnaissance Orbiter and LCROSS are the first of many robotic missions NASA will conduct between 2008 and 2016 to study, map, and learn about the lunar surface to prepare for the return of astronauts to the moon. These early missions will help determine lunar landing sites and whether resources, such as oxygen, hydrogen, and metals, are available for use in NASA's long-term lunar exploration objectives.
There's a new crater on the Moon. It's about 14 meters wide, 3 meters deep, and NASA astronomers watched it form on May 2, 2006. The meteoroid hit the Moon's Sea of Clouds (Mare Nubium) with the same energy as 4 tons of TNT. The impact created a bright fireball which scientists video-recorded using a 10-inch telescope.
A ton of meteoroids may hit the Moon every day. For the Apollo astronauts, this wasn't much of a risk - the Moon's a big place, and they didn't stay long. For future long term bases on the Moon, however, things could be riskier. Following the Vision for Space Exploration, NASA is sending astronauts back to the Moon to stay longer and build bigger bases than Apollo astronauts ever did. The odds of something precious being hit will go up.
NASA scientists are using seismic lunar data to calculate the frequency of meteoroid impacts. Clues to how often and how hard the Moon is hit lie in data from four seismometers placed on the Moon by the Apollo 12, 14, 15, and 16 missions during 1969–72. They operated until NASA turned them off in 1977, recording moonquakes and meteoroid strikes. All these data were transmitted to Earth for analysis. In theory, scientists should be able to pick out tremors from objects as small as 10 centimeters (4 inches), weighing as little as 1 kg (2.2 lb). Four inches doesn't sound like much, but traveling at cosmic velocities, a four-inch meteoroid can blast a crater as wide as your desk. According to one model, such meteoroids hit the Moon approximately 400 times a year-more than once a day. The Apollo seismic dataset can test that prediction and many others.
The Dusty Universe
Modified from: A Massive Star's Death and the Dusty Universe
When the universe was only 700 million years old, some of its galaxies were already filled with lots of dust. But where did all of this dust come from? Astronomers using NASA's Spitzer Space Telescope think they may have found the source in type II supernovae, the violent explosions of the universe's most massive stars.
Cosmic dust is an important component of galaxies, stars, planets, and even life. Until recently, astronomers knew of only two places where dust formed: in the outflows of stars that are billions of years old, and in space through the slow condensation of molecules. Neither of these explains how the universe got so dusty only a few hundred million years after its birth. Astronomers have theorized that the missing dust might be produced in supernova explosions, but evidence for this has been hard to find.
Using the space-based Spitzer and Hubble Space Telescopes and the ground-based Gemini North Telescope in Hawaii, astronomers found a significant amount of heated dust in the remains of a massive star called supernova SN 2003gd. This work shows supernovae produce copious amounts of dust; supernova explosions could account for much of the dust in the early universe.
Modified from: Hard-nosed Advice to Lunar Prospectors
Did you know that as NASA moves towards a future colony on the Moon and Mars, mining and prospecting are going to be key skills for settlers? NASA can send settlers air and water and fuel from Earth, but eventually, they'll have to learn to live off the land, using local resources to meet their needs. On the Moon, for instance, mission planners hope to find water frozen in the dark recesses of polar craters. Water can be split into hydrogen for rocket fuel and oxygen for breathing. Water is also good for drinking and as a bonus it is one of the best known radiation shields. Unlike here on Earth, deposits on the Moon aren't so well understood. Is lunar ice widespread or patchy, deep or shallow? Does it even exist? It will take unmanned missions to find answers to these questions before we can even imagine sending humans to live there for extended periods of time.
