Water findings on the moon!
INVESTIGATION OF PRESENCE OF WATER ON MOON
-BY AKSHAY DEORAS
EVENT 1-
ANNOUNCEMENT 24/09/09
MISSION-CHANDRAYAAN-1
PAYLOAD- M3 <MOON MINERAL MAPPER>
EVENT 2-
APOLLO 15 CREW TOOK SAMPLES OF THE MOON ROCKS FROM THE VOLCANIC AREA NEAR MOON'S HADLEY.
MOON'S HADLEY AN AREA IN N.HEMISPHERE OF MOON.
NASA FINDS WATER <TRACE AMOUNTS> IN JULY 2008
EVENT-3
CASSINI-HUYGENS FLYBY MOON IN 1999
EVENT-4
NASA'S EPOXI SPACECRAFT FLYBY JUNE 2009
CONCLUSIONS FROM ALL 4 MISSIONS HAVE INDICATED PRESENCE OF WATER ON MOON
THE WATER IS NOT AS SUCH IT IS ON THE EARTH IN RIVERS,SEAS ETC.
MOON-
MOON IS THE NATURAL SATELLITE OF THE EARTH.IT WAS CONSIDERED TO BE DRY TILL DECADES. MOON HAVING RARE ATMOSPHERE IS LIKE OTHER PLANETS. ONE SIDE IS IN SUN;S LIGHT AND THE OTHER IN DARKNESS.
THE SIDE OF THE MOON WHICH IS IN DARKNESS HAS A GREATER POTENTIAL FOR INTERESTING FINDINGS.
MOON IS 5.145 DEGREE TILTED WITH ITS AXIS. THIS MEANS THE POLES OF THE MOON ARE NEVER EXPOSED TO THE SUN. AS A RESULT OF THIS THERE IS NO SUCH RISE IN TEMPERATURES IN THAT AREA.
CHANDRAYAAN-1 HAD A POLAR ORBIT OF 100 X 100KM. IT HAD A PAYLOAD OF NASA AT THE TOP KNOWN AS MOON MINEROLOGY MAPPER<M3>
the moon minerology mapper
IT FUNCTIONS ON THE STUDY OF THE REFLECTION OF LIGHT FROM THE MOON. ITS A KIND OF SPECTROMETER. THE SCALE WAS USED AFTER COMPARISON FROM THE SPECTROGRAPHS OF EARTH. M3 TEAM DISCOVERED THAT THE WAVELENGTHS OF THE LIGHT BEING ABSORVED WERE SIMILAR TO THAT OF THE O-H GROUP<HYDORXYL>
WAVELENGTH- DISTANCE BETWEEN THE ADJACENT CREST AND TROUGH OF THE WAVE OVER AND BELOW THE NORMAL TO THE WAVE.
CASSINI SPACECRAFT FOUND THE HYDROXYL GROUPS EVEN IN THE SUNLIT AREA BUT THE SIGNATURE OF <OH> WAS STRONG IN THE POLAR REGION.
THE RANGE FOUND WAS-
1000 water molecule parts-per-million could be in the lunar soil
THE TEAM RETURNED TO THE RESULTS OF THE SPACECRAFT EPOXI.
EPOXI EXPANDED THE RESULT THUS PROVING THAT THE HYDROXYL GROUP IS AFFECTED DUE TO THE SUNRISE,PHYSIOGRAPHY AND OTHER FACTORS OF MOON.
THIS IS THE WORKING OF THE MOON MINERAL MAPPER. ITS A STATE-OF-ART FOR NASA....
THESE ARE THE SPECTRAL LINES. A COMPARISON OF M3 IMAGE AND APOLLO IMAGE. THE LINES HELP TO DETERMINE SURFACE COMPOSITON.
THIS GRAPH SHOWS COMPARISON OF DIFFERENT OBSERVATIONS
THE IMAGE ON RIGHT SHOWS WATER MARKS ROUND A CRATER SEEN ON LEFT
ORIGIN OF WATER.
IT CAN BE SAID THAT WATER HAS ORIGINATED DUE TO IMPACT OF COMETS,METEROIDS ETC ON THE MOON

NOTICE.
DUE TO SOME MAINTANENCE WORK,
AKSHAY'S GYAAN AND METD WEATHER STATION IS EXPECTED TO REMAIN CLOSE FOR 6 DAYS
THE OFFICE WILL CLOSE FROM TOMORROW MORNING,08 SEPTEMBER 09 TO 13 SEPTEMBER 09
METD AND AKSHAY'S GYAAN WILL REOPEN ON MONDAY,14TH SEPTEMBER 09
THIS IS DUE TO MAINTANENCE AND OFF- WORK LOAD HOURS. AKSHAY'S GYAAN WILL BE BACK WITH FRESH ARTICLES THE NEXT WEEK
INCOVENIENCE IS DEEPLY REGRETTED

RELATION OF CYCLONES WITH JUPITER
RELATION OF CYCLONES WITH JUPITER
The vortices reveal themselves as large red, white or brown spots (ovals). The largest two spots are the great red spot (GRS) and Oval BA, which is also red. These two and most of the other large spots are anticyclonic. Smaller anticyclones tend to be white. Vortices are thought to be relatively shallow structures with depths not exceeding several hundred kilometers. Located in the southern hemisphere, the GRS is the largest known vortex in the Solar System. It could engulf several Earths and has existed for at least three hundred years. Oval BA, south of GRS, is a red spot a third the size of GRS that formed in 2000 from the merging of three white ovals.
Jupiter has powerful storms, always accompanied by lightning strikes. The storms are a result of moist convection in the atmosphere connected to the evaporation and condensation of water. They are sites of strong upward motion of the air, which leads to the formation of bright and dense clouds. The storms form mainly in belt regions. The lightning strikes on Jupiter are more powerful than those on Earth. However, there are fewer of them, and the average levels of lightning activity are comparable to those on Earth.
JUPITER'S GREAT RED SPOT IS AMAZING FEATURE THAT CAN BE SEEN FROM THE EARTH THROUGH TELESCOPES AS WELL.
ITS DIMENSIONS ARE- 24–40,000 km × 12–14,000 km. it is so huge that it can accumulate two or three planets of Earth's diameter. The maximum altitude of this storm is about 8 km above the surrounding cloudtops
this red spot has been active on jupiter since 1665. its period of rotation is of six days and is expected to remain a life long on jupiter
