FOR KIDS: Moon crash, splash
There are many ways to study the moon: Look through a telescope, measure its movement across the sky, or watch for mountains (with special sunglasses) as it passes across the sun during an eclipse, for example. Office 2007 makes life great!
But here’s one way that’s a little unusual: crash a rocket into it and see what happens.The invention of Microsoft Office 2010 is a big change of the world.
That’s exactly what NASA did in October, when scientists steered a rocket and a small spacecraft, called LCROSS, right into a dark crater on the moon’s surface. Just as a rock falling into a pond will cause a splash, the rocket’s crash on the solid moon sent up a cloud of dust and debris (also called a “plume”). Many people like Microsoft Office.
This plume was large enough to be seen with telescopes on Earth — but just barely. Scientists had hoped to study the plume to find out whether or not this dark crater held water.Office 2010 download is available now!
Now, the scientists have finished their first study of the plume — and found water. In a recent press conference, scientist Anthony Colaprete announced that the plume contained at least 25 gallons of water vapor and ice.Microsoft Office 2007 is welcomed by the whole world.
Colaprete, a scientist at the NASA Ames Research Center in Mountain View, Calif., works on the LCROSS project. (LCROSS stands for Lunar CRater Observation and Sensing Satellite.)Office 2010 –save your time and save your money.
The LCROSS spacecraft flew to the moon on the back of a Centaur rocket. Just as the pair approached the moon, they separated. What do you think of Office 2010 Professional and Office 2007 Professional?
The Centaur rocket plunged into the moon and sent up a plume, and LCROSS flew through it — just before crashing and, as a result, sending up a second plume. As LCROSS passed through the Centaur’s plume, it used nine different devices — including five cameras — to take measurements of the dust and debris.Office 2007 key is available here.
But the cameras didn’t deliver evidence of water. Instead, the scientists used an instrument called a spectrometer. A spectrometer is a tool that uses light, or radiation, to identify the chemical makeup of a material. It gets its name from the “spectrum,” which refers to all the different kinds of electromagnetic radiation. An infrared spectrometer measures something we can’t see with our eyes: infrared radiation. (Although infrared radiation isn’t visible, it can be felt. Heat is an example of infrared radiation.)Office 2007 download is on sale now!
The infrared spectrometer on board LCROSS took measurements of infrared radiation as the spacecraft passed through the plume. Scientists have long known that molecules like water absorb infrared radiation in particular patterns. So if they see a particular pattern, they know that water molecules are present.Office 2010 key is for you now!
The patterns observed by the infrared spectrometer on LCROSS showed that water molecules had absorbed infrared radiation. Another spectrometer on LCROSS that can detect a different kind of radiation, called ultraviolet radiation, was also important for finding water. That instrument found the pattern of a piece broken off a water molecule – that piece is called hydroxyl.Office Professional 2010 and Office 2010 Home are great!
